盆腔淋巴结清扫术用于子宫内膜癌

目的 探讨盆腔淋巴结清扫术（清扫术）对子宫内膜癌治疗的作用。方法 分析行清扫术者１０４例，分别比较各种临床病理因素的盆腔淋巴结转移发生率，淋巴结行清扫术与非清扫术的５个生存率。结果 临床Ⅰ期子宫膜癌患者的盆腔淋巴结转移率为４．４％。深肌层浸润及低分化癌（Ｇ３）的盆腔淋巴结转移率升高，分别为３７．３％及３７．８％。临床Ⅰ、Ⅱ期患者盆深淋巴结转移与非转移的５年生存率分别为３８．９％及７４．２％，差异有

Place of Value of Pelvic Lymphadenectomy for Treatment of Endometrial Neoplasms

OBJECTIVE: To explore the therapeutic value of pelvic lymphadenectomy for endometrial carcinoma. METHODS: One hundred and four cases undergoing pelvic lymphadenectomy were analyzed. Comparisons were carried out between various clinicopathologic factors and incidence of positive node, between 5 years survival rate with pelvic lymphadenectomy and that without pelvic lymphadenectomy. RESULTS: Four point four per cent case with positive node was found in clinical stage I cases. Positive node rate increased with deep myoinvasion and G3, accounting for 37.3% and 37.8% respectively. For clinical stage I and stage II cases, the 5 year survival rate of positive node and negative node was 38.9% and 74.2% respectively, with significant difference (P < 0.005). No significant difference was found between cases with pelvic lymphadenectomy and those without pelvic lymphadenectomy (P > 0.05) in pathologic stage I and stage II cases. CONCLUSIONS: Positive pelvic node is an important prognostic factor in endometrial carcinoma. Pelvic lymphadenectomy can not improve prognosis in early stage patients with endometrial carcinoma. It is not necessary to perform pelvic lymphadenectomy for stage I case, because of low incidence of positive node.
