穿支皮瓣是乳房肿瘤整形保乳术中不可或缺的一部分,近年来一组由胸背动脉穿支皮瓣、肋间外侧动脉穿支皮瓣以及胸外侧动脉穿支皮瓣所构成的带蒂侧胸动脉穿支皮瓣成为自体乳房部分重建的新选择。与传统皮瓣相比,带蒂侧胸动脉穿支皮瓣操作... 穿支皮瓣是乳房肿瘤整形保乳术中不可或缺的一部分,近年来一组由胸背动脉穿支皮瓣、肋间外侧动脉穿支皮瓣以及胸外侧动脉穿支皮瓣所构成的带蒂侧胸动脉穿支皮瓣成为自体乳房部分重建的新选择。与传统皮瓣相比,带蒂侧胸动脉穿支皮瓣操作更简单、术后供区并发症发生率更低,美学效果也更好。本文综述了带蒂侧胸动脉穿支皮瓣在乳房肿瘤整形保乳术中的应用进展,主要包括带蒂侧胸动脉穿支皮瓣的解剖、手术步骤以及优势和局限性。 展开更多

目的:分析影响保乳术后老年乳腺癌特异性生存(breast cancer-specific survival,BCSS)的独立预后危险因素,同时构建列线图的生存预测模型,并探讨放射治疗(以下简称“放疗”)对不同危险因素分组患者的生存是否获益,以期指导临床对该类人... 目的:分析影响保乳术后老年乳腺癌特异性生存(breast cancer-specific survival,BCSS)的独立预后危险因素,同时构建列线图的生存预测模型,并探讨放射治疗(以下简称“放疗”)对不同危险因素分组患者的生存是否获益,以期指导临床对该类人群进行个体化治疗。方法:对来自美国监测、流行病学和最终结果(surveillance,epidemiology,and end results,SEER)数据库2010年至2015年诊断的20844例≥70岁保乳术后乳腺癌患者进行回顾性分析,运用倾向评分匹配法(propensity score matching,PSM)将8920例匹配患者分为放疗组(n=4460)和未放疗组(n=4460),采用Kaplan-Meier法计算放疗对总生存期(overall survival,OS)及BCSS的影响;采用多因素Cox回归分析确定BCSS的独立预后因素,并构建列线图的生存预测模型;利用受试者操作特征(receiver operator characteristic,ROC)曲线、校正曲线及临床决策曲线分析(decision curve analysis,DCA)曲线对模型进行内部验证,最后对不同危险因素分层的患者进行亚组生存分析。结果:中位随访时间71个月,放疗对保乳术后老年乳腺癌总人群OS的BCSS均有显著获益,未放疗组与放疗组OS分别为80.5%和90.1%(P<0.001);未放疗组与放疗组BCSS分别为95.0%和97.6%(P<0.001);PSM后多因素分析显示肿瘤大小>1.4 cm、腋窝淋巴结转移比例>23%、三阴性、Grade分级III级均为BCSS的独立预后危险因素(均P<0.05);ROC曲线下面积3年BCSS为0.802、5年BCSS为0.773,校正曲线显示预测线与45°参考线有良好的一致性,DCA曲线显示该模型有较高的临床净获益值;亚组分析表明:放疗显著改善了高、中风险患者5年BCSS。高风险患者中放疗组与未放疗组5年BCSS分别为92.3%和84.8%(P<0.001);中风险患者放疗组与未放疗组5年BCSS分别为97.8%和94.6%(P<0.001);低风险患者放疗组与未放疗组5年BCSS分别为99.1%和98.2%(P>0.05)。结论:放疗对不同危险因素分组的保乳术后老年乳腺癌患者的生存受益不同,因此应对该类人群是否放疗进行个体化建议,对于高风险患者及中风险患者建议进行放疗,对于低风险患者可考虑酌情省去放疗,且本研究构建的列线图生存预测模型具有良好的预测价值,可为临床提供参考。 展开更多

Younger breast cancer patients have more desire to conserve their breasts. This study was to investigate the clinicopathological characteristics and prognosis of younger breast cancer patients who received breastconserving treatment in China. METHODS The data of 232 breast cancer patients who received breast-conserving treatment in Cancer Hospital of Chinese Academy of Medical Science from January Ist, 1999 to December 31st, 2005, were collected and retrospectively analyzed. According to the age, the patients were divided into 2 groups: younger group (age ≤ 35 at the time of diagnosis) and elder group (age 〉35). The clinical features of the patients in the 2 groups were compared, and their clinical characteristics, recurrence, metastasis and survival status were summarized. RESULTS In the 232 cases, younger patients accounted for 15.9% (37/232), the elder 84.1% (195/232). By December 2008, the median time of follow-up was 54 months (ranging from 2 months to 118 months). Two patients (5.41% , 2/37) in the younger group and 5 patients (2.56% 5/195) in the elder group died. The 5-year overall survival rate (OS) in the younger and elder groups was 96.08% and 97.19%, respectively (X2= 0.69, P = 0.4066). Local recurrence (LR) or distant metastasis (DM) presented in 5 patients (5/37, 13.51%) in younger group. LR or DM presented in 10 patients (10/195, 5.13%) in elder group. The 5-year disease-free survival (DFS) rate in the younger and elder groups was 82.58% and 95.52%, respectively (X2 = 4.02, P = 0.0451). Lymph node status and the age of 35 years old or younger were the prognosis factors affecting the DFS of patients who received breast-conserving treatment (OR = 3.467, 95%CI: 1.048-11.472, P 〈0.05; OR = 0.245, 95%CI: 0.069-0.863, P 〈 0.05). Lymph node status was the only prognostic factor affecting the DFS of younger group patients (OR = 7.357, 95%CI: 1.030-52.563, P 〈0.05). CONCLUSION Though the younger and elder patients have the same mid-long term survival rate, younger patients are more likely to have recurrence or metastasis than the elder patients. Breast-conserving surgery given to the younger patients especially to the younger patients with lymph nodes positive should be contemplated cautiously. 展开更多

Axillary presentation from occult breast cancer is uncommon and continues to be a diagnostic and therapeutic challenge to physicians. Once the diagnosis of adenocarcinoma metastatic to an axillary lymph node has been confi rmed, a preoperative workup should be done. The current experience is based on several relatively small retrospective reviews and case reports. It is diffi cult to determine the best management of occult breast cancer. However, treatment of axillary lymph node dissection is recommended for local control and complete staging information. Treatment of breast should be a choice between breast conservation with whole-breast radiotherapy and mastectomy. Adjuvant systemic treatment should be offered. 展开更多
