Eur J Cancer:运动、激素替代治疗对乳腺癌风险的影响

2016-01-18 Seven L 译 MedSci原创

先前有研究报道经常运动的女性乳腺癌风险更低,但是接受激素替代治疗(HRT)的女性乳腺癌风险会增加。研究者进行了一项研究,对运动和乳腺癌风险间关系进行量化处理,同时探究HRT和其他危险因素对此关联的影响。研究者检索了相关文献,使用随机效应模型进行荟萃分析,比较运动量最大和最低水平时乳腺癌风险情况,此外还对报道了每周运动时间或每周代谢当量的研究做了剂量反应分析。荟萃分析纳入了38篇独立的前瞻性研究,涉

先前有研究报道经常运动的女性乳腺癌风险更低,但是接受激素替代治疗(HRT)的女性乳腺癌风险会增加。研究者进行了一项研究,对运动和乳腺癌风险间关系进行量化处理,同时探究HRT和其他危险因素对此关联的影响。研究者检索了相关文献,使用随机效应模型进行荟萃分析,比较运动量最大和最低水平时乳腺癌风险情况,此外还对报道了每周运动时间或每周代谢当量的研究做了剂量反应分析。

荟萃分析纳入了38篇独立的前瞻性研究,涉及16304名乳腺癌患者。运动量最高组和最低组比较得出,乳腺癌相对风险(SRR)=0.88 (95% CI 0.85, 0.90),ER+/PR+乳腺癌SRR=0.89 (95% CI 0.83, 0.95),ER-/PR-乳腺癌SRR=0.80 (95% CI 0.69, 0.92)。运动类型(职业或非职业)、肥胖和绝经状态等不会影响到风险的减少。随着运动量的增加风险下降,且没有阈值存在。六篇异质性不显著的研究表明,使用HRT治疗的女性SRR=0.78 (95% CI 0.70, 0.87),没有使用过HRT的女性SRR=0.97 (95% CI 0.88, 1.07)。此外研究者发现,每周运动150分钟以上可减少9%的乳腺癌风险,并且没有使用HRT治疗的女性,可能会减少两倍风险。

研究结果表明,运动量的增加可有效降低乳腺癌风险,但是对于没有使用HRT治疗的女性而言,因运动而降低的乳腺癌风险似乎可以忽略不计。

Eur J Cancer:乳腺癌新辅助化疗添加钙调节药效果如何?

先前有研究表明,绝经后乳腺癌患者辅助治疗时添加二膦酸盐可显著改善患者预后。研究者对4项前瞻性随机临床试验进行荟萃分析,比较II/III期乳腺癌患者新辅助化疗(CT)时候添加或不添加钙调节药唑来膦酸(ZA)的病理反应。以乳腺(pCRb)和淋巴结 (pCR)的病理完全缓解作为主要结局指标。此外研究者还对绝经后乳腺癌和三阴性乳腺癌进行了亚组分析。研究者获得了735名患者的pCRb数据,以及552名患者的

Eur J Cancer:乳腺癌新辅助化疗后残余肿瘤大小的评估,选择磁共振还是超声?

研究者进行了一项研究,评估核磁共振(MRI)和超声(US)对乳腺癌新辅助化疗后患者残余肿瘤大小评估的精确性。该研究纳入了182名侵袭性乳腺癌患者,新辅助化疗后155名进行了MRI检查,123名进行了US检查,此外研究者还获取了参与者组织病理学肿瘤大小。研究结果显示,MRI评估残余肿瘤大小<10-mm的患者有54%,高估了28%的患者,低估了18%的患者;而US检查数据分别为63%、20%和1

JNCI:乳腺癌风险评估工具BCRAT是否适用于≥75岁的老年女性

乳腺癌的风险评估工具 (BCRAT, "Gail model")现已广泛用于乳腺癌预测,BCRAT危险因素包括:年龄、种族/民族、初潮年龄、分娩年龄、家庭史、既往乳腺活检良性和异型性。但是该工具并没有在≥75岁女性中验证。因此研究组就该问题进行了一项研究。该研究共纳入73072名来自NHS和97081名来自WHI的女性参与者。NHS参与者中非西班牙籍白人更多,占96.2%,WHI中该数字为84.7

J Natl Cancer Inst:雌孕激素联合治疗会增加ER+乳腺癌的风险

先前有关于绝经后白人女性的观察性研究和随即试验表明,雌激素和孕激素联合治疗会导致雌激素受体阳性(ER+)乳腺癌风险增加。但是对于非裔美国女性是否同样存在该风险目前并不知道。因此研究者对1132例ER+和512例ER-的乳腺癌患者以及6693名对照参与者进行了一项研究,探究单独使用雌激素和联合治疗比较,对绝经后非裔美国女性ER+或ER-乳腺癌风险的影响。对照组中有57%的女性使用过单独雌激素或联合治

Cell:大规模乳腺癌功能基因组学研究结果发布,揭示肿瘤异质性,易感性和耐药机制

对乳腺癌细胞功能进行的一次迄今为止最大规模的分析调查,指出了数十个现有药物的新用途,一些药物发现新靶点及新的药物组合。作者们说,发布在1月14日《细胞》(Cell)杂志上的研究结果,可供全世界的实验室利用来鉴别其他类型癌症中的新候选药物及阐明癌细胞抵抗治疗的机制。在纽约大学Langone医学中心, Laura和Isaac Perlmutter癌症中心,及玛格丽特公主癌症中心研究人员的领导下,这一研

Eur J Cancer:曲妥珠单抗治疗转移性乳腺癌时的心脏毒性情况

已有随机对照试验评估了曲妥珠单抗治疗转移性乳腺癌的有效性和安全性,研究组进行了一项研究,探究曲妥珠单抗治疗转移性乳腺癌时,对女性的短期和长期整体生存影响,以及对女性心脏毒性的影响。研究者使用Kaplan–Meier方法评估曲妥珠单抗使用者的严重心脏事件风险,以及整体生存情况,通过Cox回归模型评估预测因子。该研究共纳入了681名使用曲妥珠单抗治疗转移性乳腺癌的患者,其中32(4.7%)名患者发生了
