This study found that administration of 500 mg/kg of L-ascorbic acid to athymic nude mice bearing human mammary carcinoma inhibited tumor cell growth. Treatment with L- ascorbic acid was also found to induce cellular DNA strand breaks and DNA crosslinks. When L-ascorbic acid was removed from cell cultures, researchers witnessed an immediate onset of spontaneous repair of single or double stranded DNA breaks. Reintroduction of L-ascorbic acid reversed this process.

This study found that guinea pigs fed high vitamin C diets experienced a significantly less mutagenic effect after being injected with K2Cr2O7 than those fed a vitamin C- deficient diet. Vitamin C-deficient animals also suffered greater mutagenic and toxic effects from hexavalent chromium. High vitamin C-guinea pigs experienced no mutagenic effects in the bone marrow or changes in microsomal enzymes in the liver following exposure to bichromate. In interpreting their results, the authors suggest that vitamin C’s protective effects likely consist in the enhanced extracellular and intracellular reduction of hexavalent chromium in the less toxic and less mutagenic trivalent chromium.

Ascorbic acid and dehydroascorbic acid have both been shown to favor ATP C+ cell multiplication in vitro at low doses and inhibit it at high doses. Ascorbic acid was found to be more effective in determining both sets of effects than dehydroascorbic acid. Fractioned rather than single administration of both substances proved to the most efficient method for inhibiting cell multiplication.

This article examined the results and methodology of a controversial case-control study involving the treatment of 100 incurable patients with 10g a day of vitamin C. The study has received criticism for not being conducted on a randomized, double-blind basis (out of ethical considerations). Instead, test cases were studied against historical controls. Results found that patients receiving vitamin C outlived controls by an average of 255 days (671%). This author considers the various criticisms the study has received, yet concludes that vitamin C is likely to have increased survival time, an average of 100% in cancer patients who had failed to respond to previous treatments.

This study found that cancer patients suffered from a decreased level of ascorbic acid relative to non-cancer patients in addition to showing that such decreases correlated with an increase in blood concentrations of malonic and pyruvic acids. When cancer patients were given 1.5 g of ascorbic acid daily over a period of 7 days, blood levels of ascorbic acid returned to almost normal and lactate and pyruvate levels exhibited a decrease. In addition to these changes, ascorbic acid deficiencies were found to result in an increased risk of postoperative complications. This risk was decreased by increasing the levels of ascorbic acid in the blood of deficient patients.

The effect of high doses of ascorbic acid (100 mg/kg daily) on tyrosine metabolism and clinical course of acute lymphoblastic leukemia was studied in nine children. Ascorbic acid administration was shown to prevent or to considerably lower the excretion of a blastogenic metabolite of tyrosine-phydroxyphenylpyruvic acid. The treatment improved clinical blood count indexes, prevented hemorrhage and was followed by an earlier onset of complete remission after chemotherapy. Although chemotherapy suppressed p- hydroxyphenylpyruvic acid excretion, its level was inordinately high as late as on day 12. It is concluded that although the effects of ascorbic acid and cytostatic drugs on p- hydroxyphenylpyruvate hydroxylase level are similar, that of ascorbic acid is more specific and is followed by a complete recovery of tyrosine metabolism.
