卵巢交界性上皮性肿瘤复发相关因素及术后生育状况的分析

目的 探讨交界性卵巢上皮性肿瘤的临床病理特点及复发相关危险因素,分析保留生育功能治疗后患者的生育状况.方法 回顾性分析北京协和医院1990年1月至2007年12月收治的186例交界性卵巢上皮肿瘤患者的临床病理资料.186例患者平均发病年龄为39.0岁,平均随访56.3个月.根据手术方式的不同,将患者分为保守性手术和广泛性手术2组:保守性手术组109例患者(58.6%),广泛性手术组77例患者(42.5%).两组患者在年龄上差异有统计学意义(P＜0.01),但在随访时间、病理类型和肿瘤分期上差异无统计学意义(P＞0.05).开腹手术151例(81.2%),腹腔镜手术35例(18.8%).利用t检验和x2检验研究数据的基本特征,利用KaplanMeier法和COX比例风险回归模型对肿瘤的复发危险因素进行单因素和多因素分析.同时,对保留生育功能手术后患者的生育状况进行评价.结果 术后有41例(22.0%)患者进行了化疗,31例(17%)患者复发,3例(1.6%)肿瘤相关死亡.多因素COX比例风险回归显示,肿瘤分期、是否行分期手术和是否有腹膜假黏液瘤是肿瘤复发的相关因素.保守性手术较广泛性手术易复发,但不影响总生存率.保守性手术组中有66例手术后有生育要求,其中有24例妊娠,术后妊娠率为36.4%.结论 卵巢上皮性交界性肿瘤的预后相对较好,但需重视对复发高危因素的评估.化疗不能明显改善患者的预后或防止复发.保守性手术较广泛性手术易复发,但并不影响远期生存率.对于有生育要求的患者应行保留生育功能治疗.手术的彻底性与肿瘤的复发相关,但范围较大的分期手术是否会造成术后的不孕,仍需大样本的研究证实.

Prognostic factors and reproductive outcomes of borderline ovarian tumors: a review of 186 patients

Objective To determine the clinicopathologieal characteristics of borderline ovarian tumors and to evaluate their prognostic factors and pregnancy rotes/fertility outcomes after conservative surgery. Methods A total of 186 patients with borderline ovarian tumors receiving treatment at our hospital from 1990 to 2007 were retrospectively studied and followed-up pest-operatively for at least six months. The effects of clinicopathological characteristics upon recurrence and mortality were analyzed by independent sample t test, Chi-square test, Kaplan-Meier and Cox proportional hazard model. Results The median follow-up time was 44 months.One hundred and nine patients underwent conservative surgery and 77 patients underwent radical surgery.Thirty-one relapses were reported.Only 3 died of disease.As demonstrated by multivariate analysis, surgical procedure, stage and pseudomyxoma peritonei were the independent prognostic factors for recurrence. Conclusion The recurrence rate of conservative surgery is higher than that of radical surgery. However, conservative surgery is safe as it does not result in a higher mortality rate.
