Could vitamin C help fight tumor cells? That's what a new study suggests, renewing a long-controversial theory. Tests in mice and in human patients suggest that a special intravenous form could help boost chemotherapy's efficacy, while reducing side effects. A study by a team of scientists from the University of Kansas focused on 25 woman with advanced ovarian cancer and found that treating them with ascorbate in addition to chemo seemed to kill cancer cells more effectively than chemo one. Their findings suggested, the researchers said, that it would be worth trying the approach on more patients. Still, the study's findings could be controversial, given the mixed results in trials using vitamin C, also known as ascorbate.
