Primary adenocarcinoma of small intestine with peritoneal dissemination treated with S-1 and CPT-11 combination chemotherapy
Abstract
A 62-year-old woman was admitted for epigastralgia, nausea and tarry stool.Abdominal CT showed a tumor to the jejunum from the duodenum, and peritoneal dissemination.Gastroduodenoscopy showed a type 2 tumor, and the histopathological examination revealed a well-to moderately-differentiated adenocarcinoma.Accordingly, she was diagnosed with primary adenocarcinoma of the small intestines and underwent surgery.The first-line chemotherapy with S-1/CPT-11 was started after surgery, and the tumor marker returned to normal.The treatment of 14 courses was continued until PD due to the enlargement of the peritoneal dissemination.Second - and third-line chemotherapy were performed; however, she died 20 months after the initial treatment.Although the incidence of primary adenocarinoma of the small intestines is relative- ly low, and there is no established chemotherapy at present, this case suggested that S-1/CPT-11may be an effective regimen for advanced primary adenocarcinoma of the small intestines.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
