WASHINGTON (Reuters) - Vitamin C supplements may undercut the effectiveness of cancer drugs including Novartis’ Gleevec, a U.S. study published on Wednesday showed.
ADVERTISEMENTWhen used on human cancer cells treated with a form of vitamin C in lab dishes, chemotherapy drugs killed 30 percent to 70 percent fewer tumor cells than usual, the scientists wrote in the journal Cancer Research.
Dr. Mark Heaney of Memorial Sloan-Kettering Cancer Center in New York and colleagues also implanted human cancer cells into mice, and found that when mice got vitamin C supplements two hours before chemotherapy, the tumors grew more quickly.
