I agree. This is only a case. Vitamin C in Cancer is a controversial topic. There were studies that it did not help end stage patients at all. However, in this case Vitamin C helped to avoid recurrence and progression and for most BC this is the most important.
But my view is enforced by Dr. Lamm who suggests taking high doses of vitamin supplements:
"Vitamin Supplementation
Epidemiologic, in vitro, and animal model studies have suggested that various vitamins, including vitamins A, B6, C, and E, may have a protective or even therapeutic effect in many cancers, including bladder cancer. Immunotherapy can markedly alter vitamin metabolism. In patients given interleukin-2 immunotherapy, serum vitamin C levels were depressed to undetectable levels in 12 of 15 patients [38],and 60% of patients were found to be hypovitaminemic for vitamin A, 80% for beta-carotene, 90% for vitamin B6, and 45% for folate [39].
We evaluated long-term administration of recommended daily allowance (RDA) multivitamins alone vs RDA multivitamins plus high doses of vitamins A, B6, C, and E in 65 BCG-treated patients with superficial transitional-cell carcinoma, one-third of whom had CIS. In this randomized double-blind study, high-dose vitamin administration (Oncovite, Mission Pharmacal) was associated with a 40% long-term reduction in tumor recurrence (P < 0.02) [40]. While natural killer cell activity was not significantly elevated following BCG therapy in patients receiving RDA vitamins, it was significantly increased in those receiving high-dose vitamins [40].
These remarkable results, which exceed the benefit currently reported with intravesical chemotherapy in superficial bladder cancer, need to be independently evaluated, but I currently recommend high-dose vitamin supplementation for all my bladder cancer patients. "
