美国外科协会统计了来自美国498所医院的16,894例病理证实的女性乳腺癌。其中可称为“微小”癌者,即不管肿瘤大小的原位癌和肿瘤直径不超过1cm 的侵润癌,共1,746例,占9.1%。本文就“微小”癌的大小、腋淋巴结有无转移、手术治疗方式及予后进行了分析,并提出了作者对“微小”癌范围的意见。在1,746例“微小”癌中,原位癌323例,无腋淋巴结转移的侵润癌1121例,有腋淋巴结转移的侵润癌302
The American Surgical Association counted 16,894 pathologically confirmed female breast cancers from 498 hospitals in the United States. Among them, “microscopic” cancers, that is, regardless of the size of the tumor in situ and invasive tumors with a tumor diameter of no more than 1 cm, a total of 1,746 cases, accounting for 9.1%. In this paper, the size of “small” cancer, the metastasis of axillary lymph nodes, surgical treatment and postoperative analysis were analyzed, and the author’s opinion on the scope of “small” cancer was presented. Among the 1,746 “microscopic” cancers, 323 were in situ carcinomas, 1121 were invasive carcinomas without axillary lymph node metastasis, and 302 were axillary lymph node metastases.
