[Low serum cholesterol level and the risk of cancer of the colon].

The study aimed at assessing a degree of low serum cholesterol relationship to carcinoma of the colon. The study involved 137 patients with carcinoma of the colon and 54 patients serving as a control group. Serum cholesterol and total proteins levels were assayed and nutritional status of the patients was analysed. It was found that serum cholesterol was significantly lower in patients with both advanced and mild cancer of the colon in comparison with a control group. Similar tendency was noted in the group of female patients with cancer of the colon but the difference between the patients with not advanced cancer and control group was statistically insignificant. Serum total proteins did not differ in patients with cancer of the colon and control group. In the group of male patients (with both stages of the cancer) in whom low serum cholesterol was noted (below 5.2 mM/L) a risk of cancer was 3-7 times higher. In female patients relative risk of cancer was significantly higher only in the advanced stages of the disease.
