2340例胰腺癌临床病例分析

目的 探讨提高胰腺癌治愈性切除相关因素和获得更佳疗效。方法 中国抗癌协会胰腺癌专业委员会回顾性分析了8省2市14大医院的1990年-2000年诊治的2340例胰腺病例。多因素生存分析采用Cox比例风险模型找出可能影响胰腺癌病人预后的独立因素。单因素生存分析用寿命表法计算,以生存曲线描述生存率,并进行Gehan比分检验。结果 COX单因素分析表明在a=0.05水平上有意义的有年龄、职业、病程、肿瘤部位、手术方式、术后胰瘘、术后肝衰、化疗、TNM分期、免疫治疗、有无肝转移、肠系膜上血管有无侵犯等变量。COX多因素分析表明在a=0.05水平上有意义的有患者年龄、手术方式、术后胰瘘、术后肝衰、化疗、免疫治疗等变量,这些变量为影响胰腺癌预后的独立因素。根治性手术者相对于未手术者,以及化疗、免疫治疗均为保护性因素。其中40岁以上的占了92.91％,40岁以下的仅占7.09％。胰头癌根治性手术组中位生存时间为 17.11个月,1年、3年和5年生存率分别为54.36％、13.47％、8.47％。结论 有必要将40岁以上的人群视为高危人群,能及时发现早期病例。各种综合治疗措施的结合都将有助于改善胰腺癌患者的生活质量和延长生存期。

Clinical analysis of pancreatic cancer: A report of 2340 cases

Objective To investigate the factors related to curable resection and efficacy of pancreatic cancer. Methods A uniform questionnaire for national survey on clinical epidemiology of pancreatic cancer was designed by Committee of Pancreatic Cancer, CACA from January 1, 1990 to December 31, 2000. A total of 2340 cases were included. Survival analysis was conducted for selected cases with complete data. Cox regression was used to screen out single and multiple risk factors. Cumulative survival rate was calculated by life table and Gehan score test. Results COX single factor analysis revealed that significant variables at α=0.05 level included age, occupation, duration of disease, location of neoplasm, operation type, postoperative pancreatic fistula, postoperative hepatic failure, chemotherapy, TNM stage, immunotherapy, liver metastasis, invasion of superior mesenteric vessle. COX multifactor analysis demonstrated that significant variables at α=0.05 level were age, surgical procedures, postoperative pancreatic fistula, postoperative hepatic failure, chemotherapy, immunotherapy. These were independent factors for the prognosis of pancreas carcinoma. Among these factors, age less than 70 years, radical operation, chemotherapy and immunotherapy were all protective factors. 92.91% of the patients were more than 40 years of age. Only 7.09% of those were less than 40. The median survival time of group of radical resection of carcinoma in head of pancreas was 17.11 months and the 1-, 3-, 5-year survival rates were 54.36%, 13.47%, 8.47% respectively. Conclusion For early diagnosis, an effective way to screen population older than 40 years is really an effective way to detect patients early and promptly. And comprehensive therapy is conducive to better quality of life and longer survival time of pancreatic cancer.
