较少的侵入性手术在化疗后淋巴结中的残留乳腺癌
大多数乳腺癌患者蔓延到淋巴结的患者在化疗后的腋窝面积中具有大多数淋巴结,以查看是否癌症仍然存在。A study conducted through the American College of Surgeons Oncology Group and led by Judy Boughey, M.D. a breast surgeon at Mayo Clinic shows that a less invasive procedure known as sentinel lymph node surgery successfully identified whether cancer remained in lymph nodes in 91 percent of patients with node-positive breast cancer who received chemotherapy before their surgery. In sentinel lymph node surgery, only a few lymph nodes, the ones most likely to contain cancer, are removed. The findings are being presented at the 2012 CTRC-AACR San Antonio Breast Cancer Symposium.
“由于在手术前用化疗治疗可以消除一些患者的淋巴结中的癌症,我们有兴趣评估是否Sentinel淋巴结她说,手术可以成功识别癌症是否仍然在淋巴结中仍然存在于淋巴结中的淋巴结。除去一些淋巴结,降低了手术并发症的风险,如麻木和手臂肿胀。
研究人员研究了756名妇女患有节点阳性乳腺癌谁接受了化疗作为初始治疗。研究参与者,637名患者患有Sentinel淋巴结和腋窝淋巴结手术。Sentinel淋巴结手术正确鉴定癌症是否患有91%的患者,其中包括255名患有节点阴性乳腺癌和326名持续节点阳性疾病患者。
研究人员还发现,40%的患者从淋巴结中完全根除癌症。该研究的假阴性率为12.6%,并且使用双跟踪器(蓝染料和放射性标记的胶体)来鉴定Sentinel淋巴结的假阴性速率显着降低。
Boughey博士表示,手术中的技术因素对于帮助确保正确分期,确定癌症多远的过程是重要的。
