title: [Clinicopathological Study of Small Intestinal Carcinoma].
abstract: We analyzed the clinicopathological characteristics, preoperative diagnosis, surgical operations, chemotherapy regimens, and prognoses of 6 patients with primary small intestinal carcinomas that were resected at our hospital between January 2004 and December 2014. The patients(3 men and 3 women)were 65 to 77 years old(mean: 70 years old). We were able to diagnose 3 patients pathologically before surgery via double balloon endoscopy and endoscopy of the large intestine. We performed partial resection of the jejunum in 3 patients, partial resection of the ileum in 1 patient, laparoscopic ileocecal resection in 1 patient, and right hemicolectomy in 1 patient. The histological type was well-differentiated adenocarcinoma in 2 patients, moderately differentiated adenocarcinoma in 2 patients, papillary adenocarcinoma in 1 patient, and poorly differentiated adenocarcinoma in 1 patient. The tumor depth was T2 in 1 patient, T3 in 2 patients, and T4 in 3 patients. The pathological stage was I in 1 patient, II A in 1 patients, II B in 2 patient, III A in 1 patient, and III B in 1 patient. The postoperative median duration of follow-up was 44 months(range: 10-127). Regarding prognosis, 5 patients are alive without recurrence, and 1 patient died of peritoneal dissemination. The overall 5-year survival rate was 75%. We suggest that it is very important to perform radical resection with lymph node dissection for patients without distant metastases.
