Vitamin C and the role in cancer care

Laboratory studies have shown the following:

Treatment with high-dose vitamin C slowed the growth and spread of prostate, pancreatic, liver, colon, malignant mesothelioma, neuroblastoma, and other types of cancer cells.
Combining high-dose vitamin C with certain types of chemotherapy may be more effective than chemotherapy alone:
Ascorbic acid with arsenic trioxide may be more effective in ovarian cancer cells.
Ascorbic acid with gemcitabine may be more effective in pancreatic cancer cells.
Ascorbic acid with gemcitabine and epigallocatechin-3-gallate (EGCG) may be more effective in malignant mesothelioma cells.
Another laboratory study suggested that combining high-dose vitamin C with radiation therapy killed more glioblastoma multiforme cells than radiation therapy alone.
However, not all laboratory studies combining vitamin C with anticancer therapies have shown benefit. Combining dehydroascorbic acid, a particular form of vitamin C, with chemotherapy made it less effective in killing some kinds of cancer cells.
