本文重点介绍肿瘤与腹泻的关系. 一、病因与发病机制 (一)肿瘤伴发感染性腹泻〔1～5、7～10〕 1.肿瘤患者因全身及局部防御功能降低,免疫功能缺损,容易被多种感染因子或致病微生物侵袭,尤其是入侵肠道.致病的微生物包括细菌、真菌、病毒和寄生虫,可引起肠道特异性炎症而致感染性腹泻.某些人体常在菌及某些毒性较弱的微生物,于机体防御功能减退时可转变为致病菌,穿通机体的防御屏障引致病情较重且难治的“机会感染”.由于肿瘤患者属消耗性疾病,可发 This article focuses on the relationship between cancer and diarrhea .A etiology and pathogenesis (A) of the tumor associated with infectious diarrhea 〔1 ~ 5,7 ~ 10〕 1. Tumor patients due to systemic and local defense function decreased, immune function defect, easy Infection by a variety of infectious agents or pathogenic microorganisms, especially the invasion of the intestine.Pathogenic microorganisms, including bacteria, fungi, viruses and parasites, can cause intestinal inflammation caused by infectious diarrhea.Some people often bacteria And some of the less toxic micro-organisms, in the body’s defense function can be reduced to pathogenic bacteria, penetrate the body’s defense barrier led to severe and refractory “opportunistic infections.” Because the tumor patients are wasting disease can be made
