Vitamin D And Chemotherapy Of Colon Cancer – Part 1 of 3

Vitamin D And Chemotherapy Of Colon Cancer. Higher vitamin D levels in patients with advanced colon cancer appear to on life response to chemotherapy and targeted anti-cancer drugs, researchers say. “We found that patients who had vitamin D levels at the highest section had improved survival and improved progression-free survival, compared with patients in the lowest category,” said go first author Dr Kimmie Ng, an assistant professor of medicine at Harvard Medical School in Boston. Those patients survived one-third longer than patients with hushed levels of vitamin D – an average 32,6 months, compared with 24,5 months, the researchers found.

The report, scheduled for presentation this week at the Gastrointestinal Cancers Symposium in San Francisco, adds more substance to suspicions that vitamin D might be a valuable cancer-fighting supplement. However, colon cancer patients shouldn’t try to boost vitamin D levels beyond the regular range, one expert said. The study only found an association between vitamin D levels and colon cancer survival rates. It did not prove cause and effect.

Researchers for years have investigated vitamin D as a potency anti-cancer tool, but none of the findings have been strong enough to warrant a recommendation, said Dr Len Lichtenfeld, deputy chief medical officer for the American Cancer Society. “Everyone comes to the same conclusion – yes, there may be some benefit, but we positively need to study it carefully so we can be certain there aren’t other factors that make vitamin D look better than it is.

These findings are interesting, and show that vitamin D may have a capacity in improving outcomes in cancer care”. In this study, researchers measured blood levels of vitamin D in 1,043 patients enrolled in a phase 3 clinical bur comparing three first-line treatments for newly diagnosed, advanced colon cancer. All of the treatments involved chemotherapy combined with the targeted anti-cancer drugs bevacizumab and/or cetuximab.
