The effects of cisplatin plus etoposide chemotherapy (PE) on the structure of proximal intestine villi and brush border were investigated in 10 patients with lung cancer. The day before starting chemotherapy (time 1); 8 days after its initiation (time 2), and one month after the 3rd course of PE (time 3) they underwent esophagogastroduodenoscopy and three biopsies were taken from the descending duodenum.

Abstract

The effects of cisplatin plus etoposide chemotherapy (PE) on the structure of proximal intestine villi and brush border were investigated in 10 patients with lung cancer. The day before starting chemotherapy (time 1); 8 days after its initiation (time 2), and one month after the 3rd course of PE (time 3) they underwent esophagogastroduodenoscopy and three biopsies were taken from the descending duodenum. Intestinal villi were examined by light microscopy; brush border by transmission electron microscopy. No significant histological changes of villous pattern were observed at times 2 and 3. The height of microvilli was reduced in seven patients at time 2 (P < 0.05). Microvilli abnormalities (i.e. rarefaction and/or heterogeneity in their height) were present in nine patients at time 2 (P < 0.05). Brush border appearance at time 3 did not differ from that at time 1. PE chemotherapy seems to have short-term toxic effects on small intestine brush border, but does not cause chronic enteropathy.
