【目的】探讨卵巢交界性上皮性肿瘤（BO T s ）的复发高危因素。【方法】收集206例BO T s患者的临床特点、治疗方法与复发情况，分析BOTs的复发高危因素。【结果】①Logistic回归分析显示，临床分期、腹膜浸润性种植和初次手术方式与BO T s肿瘤复发相关；②89例保守手术患者中，全面分期手术复发率为16．2％（6／37），显著低于非全面分期手术50％（26／52）（ P ＜0．05）。【结论】临床分期、腹膜浸润性种植和初次手术方式与BO T s肿瘤复发相关，保守手术中全面分期手术复发率较低。“,”[Objective] To explore the recurrent factors for epithelial borderline ovarian tumor (BOTs) .[Methods] Retrospective analyses were performed for a total of 206 patients with BOTs from 2001 to 2012 .[Results] Multivariate analysis showed that clinical stage ,surgical procedure and peritoneum invasive implant were the independent prognostic factors affecting recurrence .Among 89 patients with conservative treatment , 6/37 (16 .2% ) relapsed in 37 patients undergoing staging surgery while 26/52 (50% ) in 52 undergoing non‐staging surgery .And there were statistical significance ( P<0 .05) .The recurrent rate was 12 .5% in 32 pa‐tients with USO or USO+COC and 49 .1% in 57 with UOC or BOC ( P <0 .05) .Among 71 nulliparous pa‐tients with conservative surgery ,28(39 .4% ) became pregnant finally .The probabilities of pregnancy were 15% and 21 .4% in staging surgery and USO or USO+COC group respectively meanwhile those in non‐stag‐ing surgery and UOC+BOC groups 49% and 51 .1% .And the later was higher than the former ( P<0 .05) .[Conclusion] Surgery is primarily indicated for BOTs .Clinical stage ,surgical procedure and peritoneum inva‐sive implant were the independent prognostic factors affecting recurrence .And the recurrent rate is lower dur‐ing conservative staging surgery .
