摘要
目的 评价进展期胃癌患者淋巴结清扫范围与生存率的关系。 方法 共施行进展期胃癌根治术 15 8例 ,其中在D2 、D2 + 或D3 的基础上再作腹主动脉旁淋巴结清扫 (PALD组 )共 73例 ,未作腹主动脉旁淋巴结清扫 (非PALD组 )共 85例。 2组在年龄、性别、肿瘤部位、Borrmann分型、肿瘤大小、组织学类型差异无显著性意义 ,而PALD组的侵犯深度、淋巴结转移和临床病理分期均较非PALD组更晚期。 结果 PALD组手术时间为 (2 80± 93)min ,非PALD组为 (2 4 5± 91)min(P <0 0 1)。输血量PALD组为 (6 93± 32 4 )ml,非PALD组为 (46 0± 375 )ml(P <0 0 1)。 2组均无吻合口瘘、胰瘘、腹腔脓肿及肠梗阻等并发症。除PALD组腹泻发生率较高外 ,其他并发症 2组差异无显著性意义。 2组生存曲线、平均生存期、中位生存期的差异有显著性意义 (P <0 0 5 ) ,2组中淋巴结阴性、阳性患者的生存曲线、平均生存期、中位生存期差异亦有显著性意义 (P <0 0 5 )。PALD组腹主动脉旁淋巴结阴性、阳性患者的生存曲线、平均生存期、中位生存期差异有显著性意义 (P <0 0 5 )。 结论 腹主动脉旁淋巴结清扫有助提高进展期胃癌患者生存期 ,且其病死率和并发症发生率与限制性手术并无明显差别。
Objective To assess whether any correlation exists between survival and the extent of lymph-node dissection. Methods D 2,D 2 + or D 3 radical resection was performed on 158 patients with advanced gastric cancer. Among them, 73 were subjected to para-aortic lymph node dissection, (PALD group), and the other 85 were not subjected to the operation (non-PALD group). There was no significant difference in age, gender, site of tumors, type of Borrmann and histology between the two groups. The PALD group showed more advanced diseases in term of tumor invasion, lymph node metastasis and clinicopathological stage. Results Average operation time was longer in the PALD group than in the non-PALD group[(280±93) min VS. (245±91) min, ( P <0.01)].Blood transfusion volume was (693±324) ml in the PALD group, and (460±375) ml in the non-PALD group( P <0.01). No anastomotic leaks, pancreatic fistula, abdominal abscess and ileus were observed in both groups. No significant complications were found except for a higher incidence of diarrhea in the PALD group. Significant difference was found in survival curve, mean and median survival time between the two groups. The difference in survival was also found between patients with positive and negative lymph node metastasis in the PALD and non-PALD groups. Again, there was significant difference in survival between positive and negative No. 16 lymph node in the PALD group. Conclusion Para-aortic lymph node dissection offers a significant survival benefit to curable patients with advanced gastric cancer. It is similar to limited lymphadenectomy in morbidity and mortality.
