Intravenous Vitamin C as Cancer Chemotherapy

Intravenous Vitamin C as Cancer ChemotherapyIntravenous Vitamin C as Cancer Chemotherapy

by Jeffrey Dach MD

Susan is a new patient who wants hormone replacement for relief of menopausal symptoms.  While chatting during her first visit, Susan mentioned that her OB/Gyne doctor has been following her for a “pelvic mass” which was noted on a pelvic sonogram 6 months ago for fullness and discomfort in her lower abdomen.  So, before doing anything else, we sent Susan for a follow up sonogram.  Sure enough, the mass had increased in size over the last 6 months.  This is highly suspicious, so Susan was sent back to her OB/Gyne for laparoscopic surgery which revealed Susan has ovarian cancer which had already spread to the peritoneal cavity.  The surgeon then did a complete hysterectomy and debulked the peritoneal metastatic deposits.  Susan recovered quickly from surgery and was then scheduled for chemotherapy with an oncologist.

Sister Recommends IV Vitamin C For Susan

Susan’s sister told her about Intravenous vitamin C for cancer patients.   So, Susan called one of my colleagues in Boca Raton who offers IV vitamin C for cancer patients.  However, when she mentioned the IV vitamin C to her oncologist, he blew up in front of her face and practically hit the ceiling.   He was very opposed to it, saying the Iv vitamin C would reduce the effectiveness of the chemotherapy.

IV Vitamin C Makes Ovarian Cancer More Chemo-Sensitive and Reduces Adverse effects of Chemo.(26-28)

Susan’s oncologist is quite wrong about this. This question has been studied over the last 20 years, revealing that quite the opposite is true.  High dose intravenous IV vitamin C actually synergies and augments conventional chemotherapy, making the chemo drugs more effective.  This is especially true for ovarian cancer chemotherapy.  A study by Jeanne Drisko in the 2003 Journal of the American College of Nutrition (27)  and a more recent study by Yan Ma in 2014 Science Translational Medicine (28) are to this point.  They state :

“High-dose parenteral ascorbate enhanced chemosensitivity of ovarian cancer and reduced toxicity of chemotherapy.”(27-28)

Intravenous High Dose Vitamin C : Safest and Most Valuable

After reviewing the medical literature on high dose IV vitamin C for cancer patients,   Dr Michael J González and Hugh D. Riordan state in their 2005 article (29) :

“AA Ascorbic Acid (Vitamin C) is one of the safest and most valuable substances available to the physician for treating cancer.”(29)

Overwhelming Evidence

In this article we will pull together a huge volume of published studies on high dose intravenous vitamin C for the cancer patient, and demonstrate the overwhelming evidence that not only is this safe and effective along with conventional chemotherapy,  IV Vitamin C may also be regarded as an effective stand alone chemotherapy agent , killing cancer cells through a well described pro-oxidative mechanism.

Lymphoma Cells are especially sensitive to IV Vitamin C at low serum concentrations (LD50 ∼ 0.5 mmol/l) .(83-84)  Downregulating the dual anti-oxidant system with Auranofin (which inhibits thioredoxin reductase system) and a second agent such as celecoxib(87) which attenuates glutathione levels, potentiates the cytotoxic effects.(85-86)(87)

Vitamin C Mechanism  Deferentially Kills Cancer Cells

The mechanism by which high dose vitamin C kills cancer cells selectively while leaving normal cells unharmed has been extensively studied.  (see below diagram by Beuttner)(7)

Intravenous Vitamin C as Cancer Chemotherapy

Above figure from Beuttner Garry Redox Biol 2016. (7)  Fig 8(7)

Vitamin C is a pro-oxidant which produces hydrogen peroxide toxic to cancer cells which have reduced levels of the catalase enzyme needed for degradation of hydrogen peroxide.(7-8)  Extracellular spaces and normal cells contain plenty of catalase enzyme which promptly degrade the hydrogen peroxide, explaining why normal cells are unharmed.

Vitamin C Targets Cancer Stem Cells

The cancer stem cell problem is the inability of conventional cancer chemotherapy to kill cancer stem cells which are not actively replicating.  This explains the transient remissions after chemotherapy with relapse at frequent intervals after completing treatment.  Unlike conventional chemotherapy,  Vitamin C actually attacks cancer stem cells which may result in complete cure with no further relapse.(45)  Dr. Bonucelli studied the effect of Vitamin C on Breast Cancer cell cultures and states in a 2017 article in Oncotarget:(45)

“Vitamin C has two mechanisms of action. First, it is a potent pro-oxidant, that actively depletes the reduced glutathione pool, leading to cellular oxidative stress and apoptosis in cancer cells. Moreover, it also behaves as an inhibitor of glycolysis, by targeting the activity of GAPDH, a key glycolytic enzyme.

Here, we show that Vitamin C can also be used to target the CSC Cancer Stem Cell population, as it is an inhibitor of energy metabolism that feeds into the mitochondrial TCA cycle and OXPHOS.

A breast cancer based clinical study has already shown that the use of Vitamin C, concurrent with or within 6 months of chemotherapy, significantly reduces both tumor recurrence and patient mortality.”(45)

Cancer Cells Have Large Amounts of Iron – Artemisinin

In addition to lacking catalase, cancer cells contain larger amounts of iron which react with the peroxide to produce damaging ROS (Reactive Oxygen Species).(3)(46-49)  This is called Ferroptosis and is augmented with concomitant use of Artemisinin which contains an endoperoxide bridge also delivering oxidative therapy to the cancer cells.(3)

The IV version of artemisinin is Artesunate, widely available and recommended by WHO (world Health Organization) for first line treatment for severe malaria treatment of malaria.  See this poster for preparation and dosing of IV Artesunate, courtesy of  Medicines for Malaria Venture (MMV).(73-74)   Artesunate IV Dose is 2.4 mg per kg for adults.

See my previous article on artemisinin as highly effective anti-cancer agent.

Hyperbaric Oxygen or Ozone Sauna

Concomitant use of Hyperbaric oxygen or Ozone Sauna therapy augments the Pro-Oxidative Effect of IV vitamin C. (2)(54-57)

Alpha Lipoic Acid Augments Killing Effect  of Vitamin C

Alpha Lipic Acid Jeffrey DACh MDAs mentioned in my previous article, the addition of Alpha Lipoic Acid (left image) to the IV vitamin C augments the cancer cell killing effect at lower serum concentrations of vitamin C.  Alpha Lipoic Acid increases the electron flux through the mitochondria of the cancer cell, an intolerable state of affairs which triggers mitochondrial induced apoptosis of the cancer cell.(51-52)  The alpha lipoic acid (for injection) is usually given in a chaser bag to follow the IV Vitamin C infusion.  Dr Zeigler reports that daily IV infusions of 600 mg Alpha Lipoic Acid for three weeks is safe.(71-72) Drs Casciari and Riordan studied the combination of high dose IV vitamin C with alpha lipoic acid, and they write in 2001 (51) :

Lipoic acid synergistically enhanced ascorbate cytotoxicity, reducing the 2-day LC 50 in hollow fibre tumours from 34 mM to 4 mM. Lipoic acid, unlike ascorbate, was equally effective against proliferating and non-proliferating cells. Ascorbate levels in human blood plasma were measured during and after intravenous ascorbate infusions. Infusions of 60 g produced peak plasma concentrations exceeding 20 mM with an area under the curve (24 h) of 76 mM h. Thus, tumoricidal concentrations may be achievable in vivo.”  (51)

Menadione vitamin K3, Ubiquinol, PQQ

Agents like Alpha Lipoic Acid which also increase electron flux through the mitochondrial electron transport chain include Vitamin K3 (39-43), CoQ10, PQQ, etc.(29)(60)  As expected, these all synergize and augment the cancer cell killing effects of IV vitamin C.  These are all very safe vitamins, so they can be added to the IV vitamin C program.(39-44)

Chinese Skullcap Oroxylin A

The botanical plant, Chinese Skull Cap, contains oroxylin A (Baicailin see left diagram) which acts as a glycolysis inhibitor in cancer cells, and is recommended as a safe  treatment for the cancer patent.  Researchers found Oroxylin A inhibits glycolysis and the binding of hexokinase II (HK II) with mitochondria in human breast carcinoma cell lines, thus inducing apoptosis. Chinese skullcap was also effective as an anti-cancer agent  in lung cancer, AML leukemia, and glioblastoma cell models.   See my previous article on this topic for references.  Scientific Name for Chinese skullcap is : Scutellaria baicalensis Georgi available on at Elk Mountain Herbs.

Mebendazole and Ivermectin.

One may safely add add FDA approved anti-parasitic drugs Mebendazole and Ivermectin to the anti-cancer program, as they have been studied, found safe and effective as anticancer agents. See my previous article on this topic for references.

Doxycyxline and High Dose IV Vitamin C -Lethal Combination for Cancer Stem Cells

The common antibiotic Doxycycline works by blocking bacterial ribosomal protein production.  Mammalian mitochondria are remarkably similar to bacteria. The famous cell biologist, Lynn Margulis originated the endo-symbiotic theory, the idea that mitochondria evolved when bacteria where incorporated into eukaryotic single celled organisms in a symbiotic relationship. If so, then many of the routine antibiotics which target bacteria can be expected to also target mitochondrial functions in cancer cells with an added bonus of targeting cancer stem cells.  This has been found to be the case by Michal Lisanti’s goup in an elegant 2015 study entitled, “Antibiotics that target mitochondria effectively eradicate cancer stem cells, across multiple tumor types: treating cancer like an infectious disease.Oncotarget 6.7 (2015): 4569-4584.

This explains the ability of Doxycycline antibiotics to induce clinical remission in many cases of periorbital and gastric MALT lymphomas  treated with Doxycycline.  Dr. Michael Lisanti’s group published a study using in vitro breast cancer cell model showing Doxycycline and High Dose IV Vitamin C is a lethal combination for eradication of cancer stem cells.(70)

Intravenous Vitamin C For Septic Shock

Dr Paul Marik published his findings in CHEST 2016 showing that IV vitamin C is curative for septic shock patients in the ICU. (75-80)  Hydrocortisone and Thiamine was also given.  See:  Marik, Paul E., et al. “Hydrocortisone, Vitamin C and Thiamine for the Treatment of Severe Sepsis and Septic Shock: A Retrospective Before-After Study.” CHEST Journal (2016). Hydrocortisone Vitamin C and Thiamine for Sepsis Marik Paul E CHEST 2016

Safety of High Dose IV Vitamin C

Safety of IV vitamin C has been evaluated in Phase One Clinical trials in three patients with B cell lymphoma (75 grams IV ) with serum ascorbate level of greater than 15 with no adverse events.(8).  A second Clinical Trial in 35 lung cancer patients with high dose IV vitamin C , three times a week for 4 weeks, likewise showed no adverse effects.  Ascorbate serum levels were recorded in the range of 15-20 mMoles/L.(88)  Both trials showed excellent safety profile with no adverse effects.

Conclusion:

It is quite obvious high dose intravenous vitamin C is an extremely safe and beneficial therapy for cancer patients which selectively kills cancer cells while leaving normal cells unharmed. In fact, it should be offered routinely on all hospital oncology wards along with the chemo infusions.   The fact that main stream oncology has rejected and ignored  this inexpensive, safe and effective therapy that should be a routine therapy on all oncology wards is simply astounding.  You can change things by giving your doctor a copy of this article.

vitamin C IV for Cancer

1)  Mastrangelo, Domenico, et al. “Cytotoxic effects of high concentrations of sodium ascorbate on human myeloid cell lines.” Annals of hematology 94.11 (2015): 1807-1816.

The effect of high doses of intravenous (sodium) ascorbate (ASC) in the treatment of cancer has been controversial although there is growing evidence that ASC in high (pharmacologic) concentrations induces dose-dependent pro-apoptotic death of tumor cells, in vitro. Very few data are available on the role of ASC in the treatment of acute myeloid leukemia (AML). Ascorbate behaves as an antioxidant at low (physiologic), and as pro-oxidant at pharmacologic, concentrations, and this may account for the differences reported in different experimental settings, when human myeloid cell lines, such as HL60, were treated with ASC. Considering the myeloid origin of HL60 cells, and previous literature reports showing that some cell lines belonging to the myeloid lineage could be sensitive to the pro-apoptotic effects of high concentrations of ASC, we investigated in more details the effects of high doses (0.5 to 7 mM) of ASC in vitro, on a variety of human myeloid cell lines including the following: HL60, U937, NB4, NB4-R4 (retinoic acid [RA]-resistant), NB4/AsR (ATO-resistant) acute promyelocytic leukemia (APL)-derived cell lines, and K562 as well as on normal CD34+ progenitors derived from human cord blood. Our results indicate that all analyzed cell lines including all-trans retinoic acid (ATRA)- and arsenic trioxide (ATO)-resistant ones are highly sensitive to the cytotoxic, pro-oxidant effects of high doses of ASC, with an average 50 % lethal concentration (LC50) of 3 mM, depending on cell type, ASC concentration, and time of exposure. Conversely, high doses of ASC neitherdid exert significant cytotoxic effects nor impaired the differentiation potential in cord blood (CB) CD34+ normal cells. Since plasma ASC concentrations within the millimolar (mM) range can be easily and safely reached by intravenous administration, we conclude that phase I/II clinical trials using high doses of ASC should be designed for patients with advanced/refractory AML and APL.

Compared to control, ascorbate and H2O2 both caused a significant decrease in cell count both at 24-h (p<0.05 and p<0.0001 for ascorbate and H2O2, respectively) and 48-h (p<0.0001 for both ascorbate and H2O2) time points.  It may be possible to improve therapeutic outcomes by compounding  the oxidizing effect of artemisinin and certain supplements, pushing cancer cells toward oxidative overload (14).  We hypothesize that ascorbate acts more like a pro-oxidant in cancer cells due to their higher cytoplasmic iron levels.

We report a case of regression of multiple pulmonary metastases, which originated from hepatocellular carcinoma after treatment with intravenous administration of high-dose vitamin C. A 74-year-old woman presented to the clinic for her cancer-related symptoms such as general weakness and anorexia. After undergoing initial transarterial chemoembolization (TACE), local recurrence with multiple pulmonary metastases was found. She refused further conventional therapy, including sorafenib tosylate (Nexavar). She did receive high doses of vitamin C (70 g), which were administered into a peripheral vein twice a week for 10 months, and multiple pulmonary metastases were observed to have completely regressed. She then underwent subsequent TACE, resulting in remission of her primary hepatocellular carcinoma.

ascorbate seems to behave differently not just according to its dose, but rather according to the target cell, being an antioxidant for normal cells, and pro- oxidant for cancer cells.
Almost a hundred years ago, Paul Erlich, the founder of modern chemotherapy, who received the Nobel Prize for Physiology and Medicine, hypothesized the creation of the “magic bullet” for use in the fight against human disease, thus inspiring generations of scientists to devise new powerful anticancer agents: today we know that the “magic bullet” is here; ascorbate, in vitro is extremely effective and selective, as we have demonstrated in leukemic cells lines and their normal counterpart [36] … to the clinical oncologists the endeavor and responsibility to translate these wonderful data in a clinical (revolutionary) reality!.

We have previously shown that the extracellular flux of H2O2 generated by the P-AscH in the medium will increase the intracellular steady-state levels of H2O2.  Kinetic models indicate that catalase is the major antioxidant enzyme involved in the removal of H2O2 at concentrations greater than 10 µM, leading us to investigate the catalase activity in the tumor cell lines

PURPOSE:To determine the safety and the appropriate dose of intravenous l-ascorbic acid (AA) in conjunction with chemotherapy for patients with relapsed lymphoma.
PATIENTS AND METHODS:Patients with relapsed CD20-positive B-cell non-Hodgkin’s lymphoma, who were going to receive the CHASER regimen as salvage therapy, were enrolled and treated with escalating doses of AA administered by drip infusion after the 2nd course of the CHASER regimen. The target plasma concentration immediately after AA administration was >15 mM (264 mg/dl).
RESULTS: A serum AA concentration of  >15 mM was achieved in 3 sequentially registered patients, all of whom had received a 75 g whole body dose. No obvious adverse drug reaction was observed in the patients. The trial was therefore successfully completed.
CONCLUSION:Intravenous AA at a whole body dose of 75 g appears to be safe and sufficient to achieve an effective serum concentration. A phase II trial to evaluate the efficacy of intravenous AA in relapsed/refractory lymphoma patients will now be initiated.

IV site irritation may occur at the infusion site when given in a vein and not a port. This can be caused by an infusion rate exceeding 1.0 gram/minute. The protocol suggests adding magnesium to reduce the incidence of vein irritation and spasm.

Eating before the IVC infusion is recommended to help reduce blood sugar fluctuations.

IVC should only be given by slow intravenous drip at a rate of 0.5 grams per minute. (Rates up to 1.0 gram/minute are generally tolerable, but close observation is warranted. Patients can develop nausea, shakes, and chills.

We presently use a sodium ascorbate solution, MEGA-C-PLUS®, 500 mg/mL, pH range 5.5-7.0 from Merit Pharmaceuticals, Los Angeles, CA, 90065.

We advise patients to orally supplement with at least 4 grams of vitamin C daily, especially on the days when no infusions are given, to help prevent a possible vitamin C “rebound effect.” Oral alpha lipoic acid is also recommended on a case by case basis.

Vitamin C as anti-viral agent

Background: Many natural compounds were tested for the ability to suppress viral replication. The present manuscript details an analysis of high dose vitamin C therapy on patients with EBV infection.
Material and Methods: The data were obtained from the patient history database at the Riordan Clinic. Among people in our database who were treated with intravenous vitamin C (7.5 g to 50 g infusions) between 1997 and 2006, 178 patients showed elevated levels of EBV EA IgG (range 25 to 211 AU) and 40 showed elevated levels of EBV VCA IgM (range 25 to 140 AU). Most of these patients had a diagnosis of chronic fatigue syndrome, with the rest being diagnosed as having mononucleosis, fatigue, or EBV infection.
Results: Our data provide evidence that high dose intravenous vitamin C therapy has a positive effect on disease duration and reduction of viral antibody levels.
Plasma levels of ascorbic acid and vitamin D were correlated with levels of antibodies to EBV. We found an inverse correlation between EBV VCA IgM and vitamin C in plasma in patients with mononucleosis and CFS meaning that patients with high levels of vitamin C tended to have lower levels of antigens in the acute state of disease.
In addition, a relation was found between vitamin D levels and EBV EA IgG with lower levels of EBV early antigen IgG for higher levels of vitamin D.
Conclusions: The clinical study of ascorbic acid and EBV infection showed the reduction in EBV EA IgG and EBV VCA IgM antibody levels over time during IVC therapy that is consistent with observations from the literature that millimolar levels of ascorbate hinder viral infection and replication in vitro.

Human pharmacokinetics data indicate that i.v. ascorbic acid (ascorbate) in pharmacologic concentrations could have an unanticipated role in cancer treatment. Our goals here were to test whether ascorbate killed cancer cells selectively, and if so, to determine mechanisms, using clinically relevant conditions. Cell death in 10 cancer and 4 normal cell types was measured by using 1-h exposures. Normal cells were unaffected by 20 mM ascorbate, whereas 5 cancer lines had EC50 values of <4 mM, a concentration easily achievable i.v. Human lymphoma cells were studied in detail because of their sensitivity to ascorbate (EC50 of 0.5 mM) and suitability for addressing mechanisms. Extracellular but not intracellular ascorbate mediated cell death, which occurred by apoptosis and pyknosis/necrosis. Cell death was independent of metal chelators and absolutely dependent on H2O2 formation. Cell death from H2O2 added to cells was identical to that found when H2O2 was generated by ascorbate treatment. H2O2 generation was dependent on ascorbate concentration, incubation time, and the presence of 0.5-10% serum, and displayed a linear relationship with ascorbate radical formation. Although ascorbate addition to medium generated H2O2, ascorbate addition to blood generated no detectable H2O2 and only trace detectable ascorbate radical. Taken together, these data indicate that ascorbate at concentrations achieved only by i.v. administration may be a pro-drug for formation of H2O2, and that blood can be a delivery system of the pro-drug to tissues. These findings give plausibility to i.v. ascorbic acid in cancer treatment, and have unexpected implications for treatment of infections where H2O2 may be beneficial.

Ascorbic acid is an essential nutrient commonly regarded as an antioxidant. In this study, we showed that ascorbate at pharmacologic concentrations was a prooxidant, generating hydrogen-peroxide-dependent cytotoxicity toward a variety of cancer cells in vitro without adversely affecting normal cells. To test this action in vivo, normal oral tight control was bypassed by parenteral ascorbate administration. Real-time microdialysis sampling in mice bearing glioblastoma xenografts showed that a single pharmacologic dose of ascorbate produced sustained ascorbate radical and hydrogen peroxide formation selectively within interstitial fluids of tumors but not in blood. Moreover, a regimen of daily pharmacologic ascorbate treatment significantly decreased growth rates of ovarian (P < 0.005), pancreatic (P < 0.05), and glioblastoma (P < 0.001) tumors established in mice. Similar pharmacologic concentrations were readily achieved in humans given ascorbate intravenously. These data suggest that ascorbate as a prodrug may have benefits in cancers with poor prognosis and limited therapeutic options.

Early clinical studies showed that high-dose vitamin C, given by intravenous and oral routes, may improve symptoms and prolong life in patients with terminal cancer. Double-blind placebo-controlled studies of oral vitamin C therapy showed no benefit. Recent evidence shows that oral administration of the maximum tolerated dose of vitamin C (18 g/d) produces peak plasma concentrations of only 220 μmol/L, whereas intravenous administration of the same dose produces plasma concentrations about 25-fold higher. Larger doses (50–100 g) given intravenously may result in plasma concentrations of about 14 000 μmol/L. At concentrations above 1000 μmol/L, vitamin C is toxic to some cancer cells but not to normal cells in vitro. We found 3 well-documented cases of advanced cancers, confirmed by histopathologic review, where patients had unexpectedly long survival times after receiving high-dose intravenous vitamin C therapy. We examined clinical details of each case in accordance with National Cancer Institute (NCI) Best Case Series guidelines. Tumour pathology was verified by pathologists at the NCI who were unaware of diagnosis or treatment. In light of recent clinical pharmacokinetic findings and in vitro evidence of anti-tumour mechanisms, these case reports indicate that the role of high-dose intravenous vitamin C therapy in cancer treatment should be reassessed.

Also striking was the report, in a subsequent paper by Cameron, Campbell and Jack, of two vitamin C-induced complete remissions in the same patient of a stage IVB non-Hodgkins lymphoma.12 The patient was a 42 year-old truck driver who developed fever and constitutional symptoms in 1973, and was found to have a right pulmonary infiltrate. Two months later the infiltrate had evolved into mediastinal and hilar enlargement, and a pleural effusion was present. The clinical diagnosis of lung cancer was made and no treatment offered. However, when the patient then developed hepatosplenomegaly and extensive peripheral lymphadenopathy, a lymph node biopsy was carried out and the diagnosis of non-Hodgkin’s lymphoma was made. The accuracy of this diagnosis was later confirmed by expert pathologists.5,10 Although the plan at that time was for radiotherapy and cytotoxic chemotherapy, an administrative delay in obtaining the patient’s transfer to a referral center and his poor clinical condition motivated his physicians to administer intravenous vitamin C. The response was so strikingly favorable that all indications for standard lymphoma therapy promptly disappeared. Within a few days the patient experienced a return of well-being associated with complete regression of lymphadenopathy and hepatosplenomegaly. The pleural effusion resolved and the chest x-ray became normal. After three months vitamin C therapy was tapered and stopped. Four weeks after stopping vitamin C, the patient’s constitutional symptoms returned and a repeat chest x-ray again showed right hilar enlargement and a pleural effusion. The patient was started on oral ascorbic acid, but it was ineffective in preventing further clinical deterioration, so he was admitted to hospital for an intravenous ascorbic acid infusion (20 g/day for 14 days) followed by oral ascorbic acid. A slow but sustained clinical improvement resulted. As of 1979, the patient, still on vitamin C, remained in complete remission.5

Ascorbate (vitamin C) was an early, unorthodox therapy for cancer, with an outstanding safety profile and anecdotal clinical benefit. Because oral ascorbate was ineffective in two cancer clinical trials, ascorbate was abandoned by conventional oncology but continued to be used in complementary and alternative medicine. Recent studies provide rationale for reexamining ascorbate treatment. Because of marked pharmacokinetic differences, intravenous, but not oral, ascorbate produces millimolar concentrations both in blood and in tissues, killing cancer cells without harming normal tissues. In the interstitial fluid surrounding tumor cells, millimolar concentrations of ascorbate exert local pro-oxidant effects by mediating hydrogen peroxide (H(2)O(2)) formation, which kills cancer cells. We investigated downstream mechanisms of ascorbate-induced cell death. Data show that millimolar ascorbate, acting as a pro-oxidant, induced DNA damage and depleted cellular adenosine triphosphate (ATP), activated the ataxia telangiectasia mutated (ATM)/adenosine monophosphate-activated protein kinase (AMPK) pathway, and resulted in mammalian target of rapamycin (mTOR) inhibition and death in ovarian cancer cells. The combination of parenteral ascorbate with the conventional chemotherapeutic agents carboplatin and paclitaxel synergistically inhibited ovarian cancer in mouse models and reduced chemotherapy-associated toxicity in patients with ovarian cancer. On the basis of its potential benefit and minimal toxicity, examination of intravenous ascorbate in combination with standard chemotherapy is justified in larger clinical trials.

new body of data that evidences the chemotherapeutic potential of ascorbic acid

Hydrogen peroxide is most likely generated intracellularly during ascorbate’s metabolic oxidationto dehydroascorbate. Hydrogen peroxide reduces cel-lular levels of thiols and can initiate membrane lipidperoxidation.

There is a 10- to 100-fold greater content of catalase in normal cells than in tumor cells.

the combination of megadoses of IV ascorbate togetherwith oxygen, vitamin K, lipoic acid, coenzyme Q10,and small doses of copper may seem logical as part of anontoxic treatment protocol for cancer.To ascorbate’s advantage, tumor cells have an increased requirement for glucose.104To compensate for this increased need for glucose, tumor cells increase their quantity of glucose transporters.105  This action greatly enhances the entrance of either ascorbate or its oxidized form,

dehydroascorbate, into the cancer cell. This facilitates the action of ascorbate as a selective, nontoxic (to normal cells) chemotherapeutic agent.  Since AA and glucose have similar molecular structures, cellular intake of vitamin C is favored in malignant cells.

Lipoic acid (thioctic acid), an aqueous and lipid-soluble antioxidant that recycles vitamin C, decreased the dose of vitamin C required to kill 50% of tumor cells from 700 mg/dL to 120 mg/dL.

To assess the relationship between plasma vitamin C, dietary intake and subsequent survival.
METHODS:Patients with advanced cancer were recruited from a large hospice. Data were collected on demographic details, physical functioning and smoking history. An estimate was obtained of the number of weekly dietary portions consumed equivalent to 40 mg of vitamin C, the recommended daily intake. Plasma vitamin C was measured by a single blood sample. The study had local ethical approval.
RESULTS:Fifty patients were recruited (mean age 65.2 years, 28 female). Plasma vitamin C deficiency was found in 15 (30%). Dietary intake of vitamin C was correlated to plasma vitamin C (r=0.518, P<0.0001). Low dietary intake, low albumin, high platelet count, high CRP level and shorter survival were all significantly associated with low plasma vitamin C concentrations (<11 micromol/L). There was no correlation between plasma vitamin C, smoking history or physical functioning.
CONCLUSION:Vitamin C deficiency is common in patients with advanced cancer and the most important factors determining plasma levels are dietary intake and markers of the inflammatory response. Patients with low plasma concentrations of vitamin C have a shorter survival.

High-dose ascorbate sensitizes NSCLC and GBM cells to radio-chemotherapy
•O2⋅− and H2O2 increase labile iron causing cancer cell-selective ascorbate toxicity
•Therapeutic levels of ascorbate are achievable and well tolerated in GBM and NSCLC
•Cancer cell oxidative metabolism can be targeted with ascorbate for cancer therapy

Pharmacological ascorbate has been proposed as a potential anti-cancer agent when combined with radiation and chemotherapy. The anti-cancer effects of ascorbate are hypothesized to involve the autoxidation of ascorbate leading to increased steady-state levels of H2O2; however, the mechanism(s) for cancer cell-selective toxicity remain unknown. The current study shows that alterations in cancer cell mitochondrial oxidative metabolism resulting in increased levels of O2⋅− and H2O2 are capable of disrupting intracellular iron metabolism, thereby selectively sensitizing non-small-cell lung cancer (NSCLC) and glioblastoma (GBM) cells to ascorbate through pro-oxidant chemistry involving redox-active labile iron and H2O2. In addition, preclinical studies and clinical trials demonstrate the feasibility, selective toxicity, tolerability, and potential efficacy of pharmacological ascorbate in GBM and NSCLC therapy.

High-dose chemotherapies to treat multiple myeloma (MM) can be life-threatening due to toxicities to normal cells and there is a need to target only tumor cells and/or lower standard drug dosage without losing efficacy. We show that pharmacologically-dosed ascorbic acid (PAA), in the presence of iron, leads to the formation of highly reactive oxygen species (ROS) resulting in cell death. PAA selectively kills CD138+ MM tumor cells derived from MM and smoldering MM (SMM) but not from monoclonal gammopathy undetermined significance (MGUS) patients. PAA alone or in combination with melphalan inhibits tumor formation in MM xenograft mice. This study shows PAA efficacy on primary cancer cells and cell lines in vitro and in vivo.

High-dose ascorbic acid (AA) is an anti-carcinogenic, minimally toxic, metabolic therapy that targets tumor cell metabolism via an oxidative stress (OxS) mechanism. At pharmacological levels (achieved i.v.), AA delivers H2O2 to tumorous tissue upon oxidation, initiating cell death. High-dose AA has shown significant anticancer effects in vitro, in vivo, and in small-scale human reports at concentrations nontoxic to normal cells, thus having great potential as an adjuvant to the standard of care. Hyperbaric oxygen therapy (HBOT) is another non-toxic, pro-oxidative, metabolic therapy that delivers 100% oxygen at elevated barometric pressure, elevating tissue pO2 and oxygenating hypoxic tumor cells, which, when coupled with high levels of reactive oxygen and nitrogen species present in cancer cells, can further augment OxS and lead to cell death. We hypothesized that AA would induce ROS-dependent OxS and that this would be further augmented with HBOT. This study’s aims were as follows (1) to examine the anticancer effect of AA in vitro, (2) to evaluate the mechanism of AA-induced OxS, (3) to determine if HBOT and AA are synergistic.
To characterize the anticancer effects of AA in vitro, we measured cell viability and proliferation following treatment with graded concentrations of AA in mouse brain tumor-derived VM-M3 cells. We found that AA mediates cell death in a concentration-dependent manner, and that concentrations great than or equal to 0.5mM AA significantly induced cell death compared to control. We also found that concentrations > 0.05mM AA inhibit cell proliferation compared to control and 0.01mM AA at 72 and 96 hours of growth. To investigate the role of OxS in AA-induced cytotoxicity, we measured VM-M3 cell viability in the presence of AA and antioxidant N-Acetylcysteine (NAC), and found that treatment with 0.5 and 5mM NAC attenuates the OxS-induced cytotoxic effect of AA. To determine if HBOT can enhance the therapeutic effect of AA, we measured VM-M3 cell viability following treatment with HBOT and AA. We found that HBOT significantly enhanced the cytotoxic effect of 0.3mM AA.
This data indicates that AA exhibits anti-cancer effects in vitro through an OxS mechanism and that HBOT can enhance this therapeutic effect. Evidence supports the use of these minimally toxic, pro-oxidative, metabolic therapies as adjuvants to the current standard of care.

To determine if HBOT can enhance the therapeutic effect of AA, we measured measure VM-M3 cell viability following treatment with HBOT and AA. We found that HBOT significantly enhanced the cytotoxic effect of 0.3mM AA (p<0.001). To complete this aim, we will measure VM-M3 cell proliferation following treatment with HBOT, HBOT pre-treatment, and AA.

This data indicates that AA exhibits anti-cancer effect in vitro through an OxS mechanism and that HBOT can enhance this therapeutic effect. These non-toxic, pro-oxidant metabolic therapies should be further investigated as adjuvants to the current standard of care.

Effects of Ascorbic Acid on Death of Human Lymphoma Cells.
Human lymphoma cells (JLP-119) were studied in detail to determine the
effects of ascorbate on cell death. Lymphoma cells were selected
because of their sensitivity to ascorbate (Fig. 1A), the suitability of these cells for nuclear staining to characterize the mode of cell
death (16, 19, 28), and the report of a positive clinical response of
lymphoma to i.v. ascorbate (14) (unpublished work). Cells were
incubated for1hwith 0.1–5 mM ascorbate and washed, and Hoechst

PI nuclear staining was performed 18 h later to determine
the amount and type of cell death (Fig. 2 A). Ascorbate induced
concentration-dependent cell death, which was nearly 100% at 2
mM. As ascorbate concentration increased, the pattern of death
changed from apoptosis to pyknosis  necrosis, a pattern suggestive
of H2O2-mediated cell death (19). We determined the time nec-essary for cell death after exposure to 2 mM ascorbate for 1 h (Fig.2B). Apoptosis occurred by 6 h after exposure, and cell death by pyknosis was
 90% at 14 h after exposure. In contrast to lymphoma cells, there was little or no killing of normal lymphocytes and monocytes by ascorbate (Fig. 2 C)

In this paper we demonstrate that patients treated with chemotherapy and/or hematopoietic stem cell transplantation (HSCT) have highly significant reduced serum ascorbic acid (AA) levels compared to healthy controls. We recently observed in in vitro experiments that growth of both T and NK cells from hematopoietic stem cells is positively influenced by AA. It might be of clinical relevance to study the function and recovery of immune cells after intensive treatment, its correlation to AA serum levels and the possible effect of AA supplementation.

Vitamin C or ascorbic acid (AA), an essential water-soluble vitamin with many functions [1], [2], has a crucial role in cellular immune responses [3]. Patients treated with intensive chemotherapy and/or hematopoietic stem cell transplantation (HSCT) have low immune cell counts for weeks to months [4]. Meanwhile, patients are highly susceptible to infections resulting in morbidity and mortality. We recently observed that in the presence of AA, early hematopoietic progenitors commit and mature into T cells and proliferate faster [5]. Moreover, we showed that AA enhances proliferation and maturation of NK cells [6]. As AA has a major influence on (re)generation of immune cells in vitro, we executed an observational study in which AA serum values of patients with hematological malignancies treated with and without HSCT were compared with those of healthy volunteers to see if low AA levels should be considered of importance regarding immune recovery of these patients.

Vitamin C (ascorbic acid, ascorbate) has a controversial history in cancer treatment. Emerging evidence indicates that ascorbate in cancer treatment deserves re-examination. As research results concerning ascorbate pharmacokinetics and its mechanisms of action against tumor cells have been published, and as evidence from case studies has continued to mount that ascorbate therapy could be effective if the right protocols were used, interest among physicians and scientists has increased. In this review, high-dose vitamin C therapy in cancer treatment is re-evaluated.

As published by Chen et al.[51], lymphoma cells are much more sensitive to direct exposure to exogenous H2O2 as compared to normal B cells. Accordingly, lymphoma cells are among the most sensitive to L-ascorbate (LD50 ∼ 0.5 mmol/l), which generates exogenous H2O2[51]. Despite the high sensitivity in vitro, the antilymphoma activity of high dose parenteral L-ascorbate in vivo is limited [54].

Human pharmacokinetics data indicate that i.v. ascorbic acid (ascorbate) in pharmacologic concentrations could have an unanticipated role in cancer treatment. Our goals here were to test whether ascorbate killed cancer cells selectively, and if so, to determine mechanisms, using clinically relevant conditions. Cell death in 10 cancer and 4 normal cell types was measured by using 1-h exposures. Normal cells were unaffected by 20 mM ascorbate, whereas 5 cancer lines had EC50 values of <4 mM, a concentration easily achievable i.v. Human lymphoma cells were studied in detail because of their sensitivity to ascorbate (EC50 of 0.5 mM) and suitability for addressing mechanisms. Extracellular but not intracellular ascorbate mediated cell death, which occurred by apoptosis and pyknosis/necrosis. Cell death was independent of metal chelators and absolutely dependent on H2O2 formation. Cell death from H2O2 added to cells was identical to that found when H2O2 was generated by ascorbate treatment. H2O2 generation was dependent on ascorbate concentration, incubation time, and the presence of 0.5-10% serum, and displayed a linear relationship with ascorbate radical formation. Although ascorbate addition to medium generated H2O2, ascorbate addition to blood generated no detectable H2O2 and only trace detectable ascorbate radical. Taken together, these data indicate that ascorbate at concentrations achieved only by i.v. administration may be a pro-drug for formation of H2O2, and that blood can be a delivery system of the pro-drug to tissues. These findings give plausibility to i.v. ascorbic acid in cancer treatment, and have unexpected implications for treatment of infections where H2O2 may be beneficial.

Tumor cells generate substantial amounts of reactive oxygen species (ROS), engendering the need to maintain high levels of antioxidants such as thioredoxin (Trx)- and glutathione (GSH)-dependent enzymes. Exacerbating oxidative stress by specifically inhibiting these types of ROS-scavenging enzymes has emerged as a promising chemotherapeutic strategy to kill tumor cells. However, potential redundancies among the various antioxidant systems may constrain this simple approach. Trx1 and thioredoxin reductase 1 (Txnrd1) are upregulated in numerous cancers, and Txnrd1 has been reported to be indispensable for tumorigenesis. However, we report here that genetic ablation of Txnrd1 has no apparent effect on tumor cell behavior based on similar proliferative, clonogenic, and tumorigenic potential. This finding reflects widespread redundancies between the Trx- and GSH-dependent systems based on evidence of a bypass to Txnrd1 deficiency by compensatory upregulation of GSH-metabolizing enzymes. Because the survival and growth of Txnrd1-deficient tumors were strictly dependent on a functional GSH system, Txnrd1-/- tumors were highly susceptible to experimental GSH depletion in vitro and in vivo. Thus, our findings establish for the first time that a concomitant inhibition of the two major antioxidant systems is highly effective in killing tumor, highlighting a promising strategy to combat cancer.

This unique feature of tumor cells can be exploited for “selective toxicity” using the redox modifiers like l-buthionine sulfoximine (BSO), ascorbic acid, arsenic trioxide, imexon, phenethyl isothiocyanate, and motexafin gadolinium that selectively kill the tumor cells by perturbing the redox homeostasis (10).

B-cell malignancies are a common type of cancer. One approach to cancer therapy is to either increase oxidative stress or inhibit the stress response systems on which cancer cells rely. In this study, we combined non-toxic concentrations of Auranofin (AUR), an inhibitor of the thioredoxin (Trx) system, with non-toxic concentrations of buthionine-sulfoximine (BSO), a compound that reduces intracellular glutathione (GSH) levels, and investigated the effect of this drug combination on multiple pathways critical for malignant B-cell survival.

AUR interacted synergistically with BSO at low concentrations to trigger death in multiple malignant B-cell lines and primary mantle cell lymphoma (MCL) cells. Additionally, there was less toxicity toward normal B-cells. Low AUR concentrations inhibited Trx reductase (TrxR) activity, an effect significantly increased by BSO co-treatment. TrxR over-expression partially reversed AUR+BSO toxicity. Interestingly, the combination of AUR+BSO inhibited NF-κB signaling. Moreover, synergistic cell death induced by this regimen was attenuated in cells over-expressing NF-κB proteins, arguing for a functional role for NF-κB inhibition in AUR+BSO-mediated cell death.

Together, these findings suggest that AUR+BSO synergistically induce malignant B-cell death, a process mediated by dual inhibition of TrxR and NF-κB, and such an approach warrants further investigation in B-cell malignancies.

Here we show that mantle cell lymphoma (MCL) cells exhibit dramatically reduced viability following combined exposure to AUR and BSO, even at low concentrations of both agents.

There is much interest in the potential use of Cox-2 selective inhibitors in combination with other cancer therapeutics. Malignancies of hematopoietic and non-hematopoietic origin often have increased expression of cyclooxygenase-2 (Cox-2), a key modulator of inflammation. For example, hematological malignancies such as chronic lymphocytic leukemia, chronic myeloid leukemia, Hodgkin’s lymphoma, non-Hodgkin’s lymphoma and multiple myeloma often highly express Cox-2, which correlates with poor patient prognosis. Expression of Cox-2 enhances survival and proliferation of malignant cells, while negatively influencing anti-tumor immunity. Hematological malignancies expressing elevated levels of Cox-2 potentially avoid immune responses by producing factors that enhance angiogenesis and metastases. Cellular immune responses regulated by natural killer cells, cytotoxic T lymphocytes, and T regulatory cells are also influenced by Cox-2 expression. Therefore, Cox-2 selective inhibitors have promising therapeutic potential in patients suffering from certain hematological malignancies.  Cox-2 selective inhibitor celecoxib, at a dose of 400 mg/day.  More recently, our laboratory has examined the effects of both celecoxib and OSU03012 on B-CLL, as well as B cell lymphomas [21]. Treatment with either drug significantly attenuated glutathione levels. Glutathione controls damaging reactive oxygen species (ROS) production and low levels of glutathione were associated with decreased malignant B cell viability.

Ascorbic acid (AA) infusion and modulated electrohyperthermia (mEHT) are widely used by integrative cancer practitioners for many years. However, there are no safety and pharmacokinetics data in Chinese cancer patients. We carried out a clinical trial to evaluate the safety and pharmacokinetics of those methods in patients with stage III-IV non-small cell lung cancer (NSCLC). Blood ascorbic acid in the fasting state was obtained from 35 NSCLC patients; selecting from them 15 patients with stage III-IV entered the phase I study. They were randomized allocated into 3 groups, and received doses 1.0, 1.2, 1.5 g/kg AA infusions. Participants in the first group received intravenous AA (IVAA) when mEHT was finished, in the second group IVAA was administered simultaneously with mEHT and in the third group IVAA was applied first, and followed with mEHT. Pharmacokinetic profiles were obtained when they received solely IVAA and when IVAA in combination with mEHT. The process was applied 3 times a week (every other day, weekend days off) for 4 weeks. We found that fasting plasma AA levels were significantly correlated with stage of the disease. Peak concentration of AA was significantly higher in the simultaneous treatments than in other combinations with mEHT or in solely IVAA-managed groups. IVAA synergy with simultaneous mEHT is safe and the concomitant application significantly increases the plasma AA level for NSCLC patients.
