胰头癌扩大根治术的临床意义

目的 探讨扩大根治术对胰头癌的治疗意义及其适应证。方法 回顾分析了1995～1998年期间我科收治的56例胰头癌患者的临床资料,其中21例接受扩大根治术,同期35例接受胰十二指肠切除术。利用1,2,3年累积生存率和死亡率评估两种术式的疗效。借助于CT回顾性评估临床分期以探讨扩大根治术的适应证。结果 扩大根治术的1,2,3年累积生存率分别为84．8%、62．8％和39．9％;胰十二指肠切除术的1,2,3年累积生存率分别为70．8％、47．8％和17．2％,差异有显著性。两组术后3年累积死亡率分别为51．4％和42．90A,,差异有显著性,局部复发累积死亡率由胰十二指肠切除术的37．4％下降到扩大根治术的23．8%。胰十二指肠切除术组只有临床1期才能生存3年以上,而扩大根治术组临床1,2期和部分3期患者可存活3年以上。结论扩大根治术能够通过降低局部复发率而提高胰头癌患者的生存率,扩大根治术的适应证是临床1,2期和部分无严重胰外侵犯的3期患者,而不适于严重胰外侵犯的4期患者。

Significance of extended radical resection for cancer of pancreatic head

ObjectiveTo evaluate the significance of extended radical resection in the treatment of pancreatic head cancer and its indication. MethodsBetween Jan. 1995 and Dec. 1998, 56 patients with pancreatic head cancer were retrospectively reviewed, among whom 35 were treated by the Whipple operation and 21 received the extended radical resection during the same interval. ResultsThere was no significant difference between the mortality and morbidity rate of complication, though with more patients having higher clinical stages in the extended radical resection group. The 1-, 2- and 3-year survival rates were 84.8%, 62.8%, 39.9% in the extended radical resection group and 70.8%, 47.6%, 17.2% in the Whipple operation group with significant difference between the two groups. The total mortality rate was 51.4% in Whipple group and 42.9% in extended radical resection group with significant difference between the two. The 3-year cumulative rate of death from local recurrence decreased from 37.4% in the Whipple group to 23.8% in the extended radical operation group. Patients who survived for more than 3 years were only those in clinical stage (SC)1 in the Whipple group whereas they were found both in patients who had had CS1, CS2 lesions and also in some who had CS3 lesions in the extended radical resection group. ConclusionThe extended radical operation does benefit patients with pancreatic head carcinoma in CS1, CS2 and in a part of CS3 without too extensive exrtra-pancreatic invasion.
