Abstract
A limited number of case histories was analyzed and verified to examine the effect of a very low fat, moderately high fiber, and moderately reduced calorie diet on the survival and quality of life of patients with primary cancer of the pancreas, metastatic stage D2 prostate cancer, and other nutritionally linked cancers. The retrospective study of pancreatic cancer patients disclosed that 1-year survival was higher among those who modified their diets than in those for whom there was no evidence as to diet alteration. For patients with metastatic prostate cancer (stage D2), a case control study demonstrated a statistical association of dietary modification with longer survival and improved quality of life. A retrospective study utilizing questionnaires supported such dietary modifications as a useful tool in the management of nutritionally linked cancers.
