根治性全胃切除术治疗进展期贲门癌的疗效评价

目的 探讨全胃切除及系统的淋巴结清扫治疗进展期贲门癌的临床价值。方法 对387例进展期贲门癌患者施行全胃切除及D2以上的淋巴结清扫，分析贲门癌浸润胃壁深度与淋巴结转移、淋巴转移及清扫淋巴结数目与术后累积生存率的关系。结果 本组贲门癌患者术后3年、5年累积生存率分别为47.3％、34．2％，pT3、pT4的贲门癌患者pN3转移率分别为4．8％、15．2％，并且随着淋巴结转移数目的增加，3年、5年累积生存率明显下降（P〈0．01、P〈0．01），清扫15或30个以上淋巴结的贲门癌患者3年、5年累积生存率明显高于清扫少于15个淋巴结者（P〈0．05、P〈0．01）。本组贲门癌患者术后并发症发生率与病死率分别为14．2％、2．52％。结论 对进展期贲门癌患者只要条件许可应施行根治性全胃切除（D2^＋术式），必要时联合脾、胰体尾整块切除，以提高生存质量和延长生存期。

The therapeutic effect of total gastrectomy D2 + procedure for the treatment of advanced cardiac cancer

Objective To evaluate total gastrectomy and regular lymph node dissection for the treatment of advanced cardiac cancer. Methods Three hundred and eighty-seven patients with advanced cardiac cancer underwent total gastrectomy D2+ procedure. The relationships between depth of invasion, lymph node metastasis,the number of metastastic lymph nodes dissected and postoperative survival rate were analyzed. Results The 3-year and 5-year survival rates were 47.3% and 34.2% , respectively. Metastatic rate of N3 lymph node was 4. 8% and 15. 2% in advanced cardiac patients of PT3 and PT4, respectively. Survival rates significantly decreased along with the increase of lymph node metastasis. The 3-year and 5-year survival of patients who had less than 15 lymph nodes dissected was significantly poorer than those who had more than 15 lymph nodes dissected, respectively. The postoperative complication rate and mortality rate of the two groups were 14. 2% and 2. 52% , respectively. Conclution To improve the quality of life and survival rate, D2 + radical total gastrectomy should be performed for advanced cardiac cancer, and when indicated resection of spleen and/or body and tail of the pancreas should be performed.
