目的 探讨影响Ⅰ~Ⅱ期子宫内膜癌患者复发及预后的临床病理因素.方法 选择1990年10月-2010年10月间北京大学人民医院收治的临床病理资料完整并完成随方的初治Ⅰ~Ⅱ期子宫内膜癌患者398例,回顾性分析影响患者复发及预后的临床病理因素.结果 398例Ⅰ~Ⅱ期子宫内膜癌患者中,复发36例,复发率为9.0%(36/398),其中58.3%(21/36)的患者在5年内出现复发.Ⅰ~Ⅱ期子宫内膜癌患者的复发率,年龄≤50岁[1.9% (2/103)]低于>50岁者[11.5%(34/295),P=0.004],子宫内膜样腺癌[8.0%(27/338)]低于浆液性腺癌[6/14,P=0.000],病理分级为G3者[17.9%(10/56)]高于G1~ G2[7.4%(25/338),P=0.022],肌层浸润深度≥1/2者[16.2%(16/99)]高于无肌层浸润[3.4%(2/59)]、肌层浸润深度<1/2者[7.5%(18/240),P=0.011],肿瘤长径>2 cm者[17.1% (19/111)]高于≤2 cm者[5.9%(17/287),P=0.000],腹水细胞学检查阳性者[23.8% (5/21)]高于阴性者[6.9% (22/317),P=0.019],ER阴性者[20.8%(11/53)]高于阳性者[5.5%(16/293),P=0.000],PR阴性者[30.0%(15/50)]高于阳性者[4.1%(12/295),P=0.031],以上各指标分别比较,差异均有统计学意义;而手术病理分期、淋巴脉管癌栓、术前血清CA125水平及p53、PTEN蛋白表达与患者复发无关(P>0.05).单因素生存分析显示,患者年龄、病理类型、病理分级、肌层浸润深度、肿瘤长径、腹水细胞学检查、PR表达对患者无瘤生存率(DFS)及总生存率(OS)均有显著影响(P<0.05);而ER表达仅对患者DFS有显著影响(P<0.05).结论 Ⅰ~Ⅱ期子宫内膜癌患者的复发及预后与年龄、病理分级、病理类型、肌层浸润深度、肿瘤长径、腹水细胞学检查结果及ER、PR表达有关.Ⅰ~Ⅱ期子宫内膜癌患者5年内复发率较高,因此在初治后5年内密切随访是必要的.
Objective To explore the high-risk clinicopathological features for the recurrence and prognosis of endometrial carcinoma diagnosed as International Federation of Gynecology and Obstetrics (FIGO) stages Ⅰ and Ⅱ.Methods Three hundreds ninety-eight consecutive patients with clinical stage I,Ⅱ endometrial adenocarcinoma underwent primary surgical therapy between Oct.1990 to Oct.2010 were studied retrospectively to analyze the correlation between clinicopathological risk factors and the disease recurrence or prognosis.Results Thirty-six patients (9.0%,36/398) developed recurrence,21 of them (58.3%,21/36) relapsed within 5 years of treatment.The results shown that the disease recurrence were significantly associated with clinicopathological factors including:age [≤50 years versus 〉 50 years,1.9% (2/103) versus 11.5% (34/295) ; P =0.004] ; histologic types [adenocarcinoma versus serous papillary adenocarcinoma,8.0% (27/338) versus 6/14; P =0.000] ; tumor grade [grade 1,2 (7.4%,25/338) versus grade 3 (17.9%,10/56) ;P =0.022] ; depth of myometrial invasion [none (3.4%,2/59) versus 〈 1/2 (7.5 %,18/240) versus ≥ 1/2 (16.2%,16/99) ; P =0.011] ; tumor size [≤ 2 cm (5.9%,17/287) versus 〉 2 cm (17.1%,19/111) ; P =0.000].peritoneal cytology [negative (6.9%,22/317) versus positive (23.8%,5/21) ;P =0.019] ;ER status[negative (20.8%,11/53) versus positive (5.5%,16/293) ; P =0.000] ; PR status [negative (30.0%,15/50) versus positive (4.1%,12/295) ; P =0.031].But lympho vascular space invasion (LVSI),p53 or PTEN status were not significant effect on recurrence and prognosis.Univariate analysis of survival indicated that age,histology,tumor grade,depth of myometrial invasion,tumor size,peritoneal cytology and PR status were correlated with overall survival(OS) and disease free survival (DFS ; all P 〈 0.05),while ER status only impact on DFS (P 〈 0.05).Conclusions The results showed that age,histologic type of carcinoma,
