Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    What is the effect of vitamin D blood levels on colon and rectal cancer?

    Low vitamin D status has long been implicated in colorectal cancer.

    This study looks at the relation between blood levels of vitamin D and the risk of colon, colorectal, and rectal cancer in men and women.

    First, the details.

    • 179 men with colorectal cancer were compared to 356 similar men but without cancer.
    • These results were combined with previously published results from the Nurses? Health Study, a large group of women.

    And, the results.

    • After pooling the findings from the 2 groups, higher plasma 25(OH) vitamin D blood levels were significantly associated with a lower risk of both colorectal cancer and colon cancer.
    • Interestingly, opposite relationships were found between plasma 25(OH) vitamin D blood levels and the risk of rectal cancers in men (higher levels lead to greater risk) and women (higher levels lead to lower risk).

    The bottom line?
    The authors note that the major deficiency of the study is that conclusions are based on just one vitamin D blood level taken from each patient.

    We probably haven’t gotten to the bottom line yet.
