Objective:Now breast cancer still ranks the first in the women cancer incidence,and is also one of common cause of cancer-related death.The most frequent subtype of breast cancer is hormone receptor-positive subtypes,and premenopausal patient accounts for a large proportion.So a further of comprehensive breast cancer treatment for premenopausal patients has important clinical significance.Five years of tamoxifen(TAM) treatment is the cornerstone of current pre-menopausal hormone-receptor-positive breast cancer treatment.But there are some studies which have showed that in tamoxifen or aromatase inhibitors (AI) plus GnRHα induced ovarian suppression could produce more survival benefit.In these years,the st Gallen conference and ASCO guidelines have discussed GnRHα induced ovarian suppression for premenopausal breast cancer treatment.The main purpose of this study is to systematic evaluate the survival benefit of GnRHα induced ovarian suppression for premenopausal breast cancer patient,and to explore the optimal target population.In addition,using network meta-analysis,we can also evaluate the different drugcombination and course of treatment,and figure out the best drug combination of GnRHα induced ovarian suppression and the best course of treatment.

目的:回顾性分析102例乳腺癌患者手术治疗前后的营养状况,为乳腺癌患者进行营养支持提供指导.方法:运用回顾性调查的方法,对乳腺癌患者手术前后反映营养状况的相关血生化指标、血常规指标进行分析.结果:手术前后乳腺癌患者外周血TC、ALB、TP、PA、RBC、HB、TLC均有显著性差异(P<0.05).结论:手术会造成乳腺癌患者的营养状况下降,乳腺癌患者术后需注意增加营养支持治疗.

乳腺癌已成为危害中国妇女健康最常见的恶性肿瘤之一,早期诊断能显著改善乳腺癌患者的预后.乳腺微钙化灶在乳腺癌早期诊断有重要的临床意义,由于微钙化临床无法触及,如何精确定位并完整切除则成为乳腺外科亟待解决的问题.目前,在国内外金属钩针定位开放手术(WGL)已逐渐被穿刺活检(VAB&CNB)取代,但对于特殊部位的钙化,WGL仍有优势.本研究改进WGL,首创钼靶联合超声双定位后使用自主研发的乳腺精准旋切器

目的:直径≤1cm的小乳腺癌恶性特征不明显,容易误诊.本文探讨直径≤1cm乳腺小肿块的超声乳腺影像报告与数据系统(BI-RADS)联合超声弹性成像(UE)的应用价值.方法:回顾性分析231例患者共258个肿块,最大直径≤1cm,进行超声BI-RADS分类,联合UE评分法对其进行调整,并与术后病理结果进行对照,采用受试者操作特征(ROC)曲线评价两者联合应用对乳腺小肿块的诊断价值.结果:258个乳腺
非晡乳期乳腺炎(Non Lactational Mastitis,NLM)不是一个病名,而是一组发生在女性非哺乳期的病原学证据不明的非特异性炎症,可是一种局部病变,也可是全身疾病的一种局部表现,是发生在非哺乳期的乳腺炎过程.NLM是乳腺学科争议较大,诊治棘手的一组疾病。针对不同类型阐述了疾病的病理机制、临床诊断和治疗。
