Periampullary tumors form a clinical entity with common symptoms, similar therapeutic options, unsatisfactory resectability rates and unfavorable prognosis. From April 1970 until March 1994, one hundred and twenty-seven patients with periampullary carcinoma were operated by our surgical team. In 48 of these patients, a resection for cure was performed (38%). Resectability rates varied according to the origin of these tumors, i.e., pancreas-20%, ampulla-76%; distal bile duct-71%, periampullary duodenum-88%. Pancreatic tumors showed a different resectability rate from the other periampullary carcinomas (p = 0.04). Forty-two of these patients had a pancreatoduodenectomy and in the remaining 6 cases a total pancreatectomy was performed. Fifteen patients had major post-operative morbidity (31%) and 8 of these cases died in-hospital (17%). Follow-up data was available in 81% of the patients, survival estimates were calculated according to the Kaplan-Meier method and survival comparisons were made with the Log-rank test. Median survival for resected pancreatic carcinoma was 6 months and for resected tumors of the ampulla 37 months. In this group of patients, pancreatic tumors showed a different survival rate from the remaining periampullary tumors (Log-rank-p = 0.002). This work evidences the need to improve management of periampullary tumors, particularly in-hospital mortality and long-term survival. To achieve these goals, patients with periampullary tumors should be treated in specialized centers and research to improve local and systemic control of this disease should be pursued.
壶腹周围肿瘤构成了一个具有共同症状、相似治疗选择、切除率不尽人意且预后不佳的临床实体。从1970年4月至1994年3月,我们的外科团队对127例壶腹周围癌患者进行了手术。其中48例患者进行了根治性切除(38%)。切除率因这些肿瘤的起源而异,即胰腺 - 20%,壶腹 - 76%;远端胆管 - 71%,壶腹周围十二指肠 - 88%。胰腺肿瘤的切除率与其他壶腹周围癌不同(p = 0.04)。这些患者中有42例行胰十二指肠切除术,其余6例行全胰切除术。15例患者术后出现严重并发症(31%),其中8例在住院期间死亡(17%)。81%的患者有随访数据,根据Kaplan-Meier方法计算生存估计值,并使用Log-rank检验进行生存比较。切除的胰腺癌患者的中位生存期为6个月,壶腹肿瘤患者为37个月。在这组患者中,胰腺肿瘤的生存率与其余壶腹周围肿瘤不同(Log-rank - p = 0.002)。这项工作表明需要改善壶腹周围肿瘤的管理,特别是住院死亡率和长期生存率。为实现这些目标,壶腹周围肿瘤患者应在专科中心接受治疗,并应开展研究以改善对该疾病的局部和全身控制。
