Abstract

Parasitological examination of feces was carried out for 55 patients with diagnosed colorectal cancer before chemotherapy. Except for Cryptosporidium sp., no other intestinal parasites were found in the specimens; moreover, only the patients with watery diarrhea were Cryptosporidium sp.-positive by enzyme immunoassay. Prevalence of infection in the group of patients with diarrhea (23 persons) was 43.5%, whereas it was 18% for the entire group of patients under study. Coproantigens of this parasite were detected primarily in the patients with tumors located on the left side (in the sigmoid and descending colon).

摘要

对55例确诊为结直肠癌的患者在化疗前进行了粪便寄生虫学检查。除隐孢子虫属外，标本中未发现其他肠道寄生虫；此外，仅腹泻水样便的患者通过酶免疫测定隐孢子虫属呈阳性。腹泻患者组（23人）的感染率为43.5%，而整个研究患者组的感染率为18%。这种寄生虫的粪便抗原主要在左侧肿瘤患者（乙状结肠和降结肠）中检测到。
