[Disorders of intestinal absorption in patients treated with cytostatic chemotherapy].
We have investigated the acute and chronic side effects of cancer chemotherapy on the intestinal absorption of adult patients with neoplastic diseases. D-xylose absorption was reduced by 35% in 34 of 50 patients within 48 hours after one course (p less than 0.001), while the vitamin B12 absorption was diminished by 41% in 27 of 38 patients (p less than 0.001). The serum digoxin level fell in 7 of 8 patients by 43% at the first day (p less than 0.01) and normalized after one week. Electron microscopy of the jejunal biopsy specimens revealed damages of the microvilli and defects in the glycocalix. Chronic effects, which were measured after several courses and a pause of four weeks, showed a diminished D-xylose absorption of 36% in 16 of 19 cases (p less than 0.01). Vitamin B12 absorption was reduced by 37% in 11 of 13 patients (p less than 0.01). Microscopical investigations of the jejunum revealed a shortening of the villi and a destruction of microvilli. Acute and chronic malabsorption after cancer chemotherapy should be considered in patients, who are treated with enteral medication and nutrition.
