[Blood cholesterol in patients with cancer].

Cholesterolaemia values have been investigated in a simple of colon cancer patients and in two control samples consisting of age and sex corresponding subjects suffering respectively from peripheral arteriopathy and minor pathologies (hernias and varices). The study was extended subsequently to a sample of subjects suffering from thyroid neoplasia and two similarly constituted control samples. Cholesterolaemia was significantly lower in colon cancer patients than in the control samples whereas in subjects suffering from thyroid cancer, statistical significance was not attained even though a similar reduction was recorded. The reduction in cholesterol in cancer patients is, in the light of the most recent studies, an effect of cancer on cholesterolaemia, thus giving the lie to the theory that low blood cholesterol is a factor favouring the onset of cancer, and is a finding with by no means indifferent repercussions on the study of the behaviour and physiopathology of cancers.
