目的 分析年轻乳腺癌患者保乳治疗(BCT)后局部复发的影响因素.方法 收集2005年1月至2010年1月于该院行BCT的患者360例,进行回顾性分析.收集患者临床和病理资料,包括肿瘤大小、淋巴结状态、肿瘤TNM分期、病理类型、切缘状态、人表皮生长因子受体2(Her-2)、雌激素受体(ER)/孕激素受体(PR)和Ki-67.采用单因素分析及Logistic回归分析进行独立危险因素分析.结果 患者行BCT后局部复发率为10.56％.单因素分析显示,肿瘤大小、TNM分期、病理分型和ER/PR比值均对年轻患者BCT后局部复发无影响(P＞0.05);淋巴结转移、切缘状态、Her-2和Ki-67均可影响年轻患者BCT后的局部复发率(P＜0.05).Logistic回归分析显示,淋巴结状态、Her-2和切缘状态为年轻患者BCT后局部复发的独立危险因素(P＜0.05).结论 淋巴转移、Her-2阳性和切缘状态是年轻乳腺癌患者行BCT后局部复发的影响因素.%Objective To investigated the influence factors of local recurrence after breast conserving therapy (BCT) in young patients with breast cancer.Methods A total of 360 cases of BCT in this hospital from January 2005 to January 2010 were collected and retrospectively analyzed.Clinical and pathological data included the tumor size,lymph node status,tumor TNM stage,pathological type,margin status,human epidermal growth factor receptor 2 (Her-2),estrogen receptor (ER)/progesterone receptor (PR) and Ki-67.The independent risk factors were analyzed by adopting the univariate analysis and Logistic regression analysis.Results The total recurrence rate of young patients with BCT was 10.56％.The univariate analysis showed that the tumor size,TNM stage,pathological type and ER/PR ratio had no influence on local recurrence after BCT in young patients (P＞0.05);lymph node metastasis,cutting edge status,Her-2 and Ki-67 could influence the local recurrence rate after BCT in young patients (P＜0.05).The Logistic regression analysis showed that the lymph node status,Her-2 and margin status were the independent risk factors for local recurrence after BCT in young patients (P＜0.05).Conclusion Lymph node metastases,Her-2 positive and cutting edge status are local recurrence risk factor after BCT for young patients with breast cancer
