目的分析麦默通（MMT）治疗乳腺良性肿块预后不良的危险因素。方法回顾性分析310例MMT治疗乳腺良性肿块患者的临床资料，根据随访6个月间的预后状况分为预后良好组（n=286）和预后不良组（n=24）。比较两组一般资料及围术期情况，使用logistics回归分析MMT治疗乳腺良性肿块预后不良的危险因素。结果①多发肿块者、肿块边界不清晰者、肿块最大直径＞2 cm者、血肿形成者、术后瘀斑形成者的MMT治疗后预后不良率更高（P＜0.05）；②经logistics回归分析：肿块数量多发、肿块边界不清、肿块最大直径＞2 cm及血肿形成是MMT治疗乳腺良性肿块预后不良的独立危险因素（P＜0.05）。结论肿块数量、肿块边界、肿块最大直径及血肿形成是MMT治疗乳腺良性肿块预后不良的独立危险因素，临床应用MMT治疗乳腺良性肿块时应严格把握手术适应证。

ObjectiveTo analyze the risk factors of poor prognosis in patients with benign breast masses after treatment by Mammotome（MMT）. MethodsThe clinical data of 310 benign breast masses patients treated by MMT were retrospectively analyzed. According to the prognosis during 6-month follow-up, the patients were divided into good prognosis group (n=286) and poor prognosis group (n=24). The general data and perioperative conditions were compared between the two groups. Logistic regression analysis was used to assess the risk factors for the poor prognosis in patients with benign breast masses after treatment by MMT. Results① The rate of poor prognosis after MMT was higher in the patients with multiple masses, indistinct mass boundary, maximal diameter＞2cm, hematoma formation and postoperative ecchymosis formation (P＜0.05). ②The logistic regression analysis showed that the multiple masses, indistinct mass boundary, maximal diameter＞2 cm, hematoma formation were the independent risk factors for the poor prognosis in the patients with benign breast masses after treatment by MMT (P＜0.05). ConclusionThe quantity, boundary and maximal diameter of the masses, and hematoma formation are the independent risk factors for poor prognosis in the patients with benign breast masses after treatment by MMT. Surgical indications should be strict when treating benign breast masses by MMT.
