目的探讨胃肠道类癌的诊断和治疗方法及影响预后的因素。方法回顾分析我院1980年1月至2005年1月收治的胃肠道类癌49例的临床资料。结果49例患者中,胃类癌13例,直肠类癌16例,阑尾类癌7例,结肠类癌12例,回肠类癌1例。术前误诊71.4%,其中胃类癌、阑尾类癌和回肠类癌全部误诊,直肠类癌25.0%、结肠类癌83.3%误诊。肿瘤直径在2cm以内、无肌层侵犯和淋巴结转移者1、3、5年累计生存率为100%、100%和96.9%;肿瘤直径超过2cm、侵犯肌层或有淋巴结转移者累积1、3、5年累计生存率为70.3%、62.3%和58.4%。结论胃肠道类癌术前误诊率高,预后主要取决于肿瘤的大小、有无肌层侵犯或淋巴结转移。
Objective To investigate the diagnosis and treatment of gastrointestinal carcinoid and prognostic factors. Methods A retrospective analysis of our hospital from January 1980 to January 2005 admitted to gastrointestinal carcinoid 49 cases of clinical data. Results Among the 49 patients, there were 13 cases of gastric carcinoid, 16 cases of rectal carcinoid, 7 cases of appendix carcinoid, 12 cases of colon carcinoid and 1 case of ileal carcinoid. Preoperative misdiagnosis of 71.4%, of which stomach cancer, appendix cancer and ileal carcinoid all misdiagnosed, rectal carcinoid 25.0%, 83.3% of colon carcinoid misdiagnosed. The cumulative survival rates at 1, 3 and 5 years were 100%, 100% and 96.9% for those with tumor diameter less than 2 cm and no myometrial invasion and lymph node metastasis; those with tumor diameter more than 2 cm and those with muscle invasion or lymph node metastasis had a cumulative 1,3 The 5-year cumulative survival rates were 70.3%, 62.3% and 58.4%. Conclusion Gastrointestinal carcinoid preoperative misdiagnosis rate is high, the prognosis mainly depends on the size of the tumor, with or without myometrial invasion or lymph node metastasis.
