晚期子宫内膜癌患者的治疗及预后分析

目的 探讨晚期(Ⅲ～Ⅳ期)子宫内膜癌的治疗方法及预后影响因素.方法 选择1996年1月至2006年12月间收治的晚期子宫内膜癌患者118例,对其治疗方法及预后影响因素进行回顾性分析,患者随访至2007年12月,平均随访26个月.结果 随访期内,共33例患者死亡,占28.0%;25例患者术后出现疾病进展,占21.2%.Ⅲ、Ⅳ期患者的3年总生存率分别为78.3%和39.4%,子宫内膜样腺癌和非子宫内膜样腺癌患者的3年总生存率分别为69.3%和42.0%,分别比较,差异均有统计学意义(P<0.05).4例仅有腹水细胞学检查阳性的Ⅲa期患者,术后未行辅助治疗,现已平均随访16个月均无瘤生存.单因素分析显示,手术病理分期、病理类型、肌层浸润深度、病理分级、后腹膜淋巴结切除术(包括盆腔淋巴结切除或加腹主动脉旁淋巴结切除术)和术后辅助联合放化疗与预后明显相关(P<0.05).多因素分析显示,手术病理分期和肌层浸润深度与预后明显相关(P<0.05).对不同治疗方式分析显示,行后腹膜淋巴结切除术患者的预后明显优于未行该手术者(P<0.05);术后残留灶直径≤1 cm患者的预后明显优于残留灶直径>1 cm者(P<0.05);术后行辅助联合放化疗患者的预后明显优于未行联合放化疗和仅行放疗或化疗者(P<0.05).结论 手术病理分期和肌层浸润深度是影响晚期子宫内膜癌患者预后的独立的危险因素.治疗应在满意的肿瘤细胞减灭术和后腹膜淋巴结切除术的基础上,除仪腹水细胞学检查阳性的Ⅲa期患者外,术后均应辅以联合放化疗,以改善患者的预后.

Combined treatment and prognostic factors for stage Ⅲ and Ⅳ endometrial carcinoma

Objective To evaluate prognostic factors and treatment of patients with advanced stage endometrial cancer. Methods One hundred and eighteen patients with advanced stage endometrial cancer were treated in our hospital between January 1996 and December 2006. The treatment and prognosis were retrospectively analyzed. The mean follow-up time was 26 months. Results During the follow-up, 33 cases (28.0%) died and 25 patients(21.2% ) had disease progression. The 3-year overall survival for patients with stage Ⅲ and stage Ⅳ was 78. 3% and 39. 4%, and for endometrioid and nonendometrioid endometrial carcinoma was 69. 3% and 42. 0%, respectively. Four patients with positive cytology only were followed closely after surgery and were free of disease up to the report time. Patients with late stages, deep myometrial invasion, nonendometrioid endometrial cancer, poor differentiation, without lymphadenectomy and without radiochemotherapy after surgery were associated with a worse prognosis by univariate analysis (P < 0. 05 ),while in a multivariate analysis only late stages and deep myometrial invasion were associated with a poor prognosis ( P < 0. 05 ). The patients who received lymphadenectomy and whose residual disease after the surgery was less than 1 cm had better prognoses than those otherwise(P <0. 05). The patients who received postoperative radiochemotherapy had better prognoses than those who did not ( P <0. 05 ). Conclusions Pathological stage and myometrial invasion are independent prognostic factors for late stage endometrial cancer. Satisfactory cytoreduction surgery and lymphadenectomy, followed by postoperative radiochemotherapy, except for stage Ⅲa patients with positive cytology only, are recommended in order to improve prognosis.
