目的 :探讨腋窝淋巴结转移阳性的乳腺浸润性导管癌患者的体视学指标Sv(癌巢表面积密度 )与预后的关系 ,以寻找一个独立判断预后的量化指标。方法 :统计 2 0 6例乳癌患者的Sv和预后数据 ,并进行分析。结果 :提示Sv<4 .4和Sv >5 .5是两个有意义的参数 ,前者可以认为是 5年生存的安全值 ,后者可认为是 5年生存的危险值。结论 :体视学方法测定乳腺浸润性导管癌的Sv ,方法简单易行 ,所获参数可靠 ,可作为反映其 5年生存情况的一个重要指标。
Objective: To investigate the relationship between stereological Sv (cancer nest surface area density) and prognosis in patients with breast invasive ductal carcinoma with axillary lymph node metastasis, in order to find a quantitative index to independently judge the prognosis. Methods: Sv and prognostic data of 206 breast cancer patients were collected and analyzed. Results: It is suggested that Sv <4. 4 and Sv> 5. 5 are two meaningful parameters. The former can be regarded as the safety value of 5-year survival and the latter can be considered as the 5-year survival risk value. Conclusion: Stereological method for the determination of Sv in invasive ductal carcinoma of the breast is simple, reliable and reliable, which can be used as an important index to reflect its 5-year survival.
