The influence of radiotherapy and chemotherapy on the vitamin status of cancer patients.
The influence of external abdominal irradiation and cytostatic therapy on the vitamin status was studied in patients with cancer of the uterus, bladder or prostate and in patients with malignant lymphoma. It was found that the vitamin status of these patients at the beginning of therapy in general was adequate, though vitamin A and vitamin D levels were reduced. During radiotherapy decreases of vitamin E, vitamin C, vitamin B12 and folic acid levels were observed. Chemotherapy caused a decrease of the folic acid levels after a few months. No clinical symptoms of vitamin deficiency were observed.
