An analysis of 1,686 surgically treated carcinomas of the breast in one community showed no statistically significant differences in five- and ten-year survival for simple, modified radical, or radical mastectomy. Further confirmation was obtained by computation of relative survival which in addition showed that older women more nearly approach normal life expectancy than younger ones. Bilaterality was found to be a decreasing function of age. Patients with medial and lateral tumors did not have significantly different rates of survival or sites of distant metastases.
对某一社区1686例接受手术治疗的乳腺癌病例分析显示，单纯乳房切除术、改良根治术或根治性乳房切除术在5年和10年生存率方面无统计学显著差异。通过计算相对生存率进一步证实了这一点，此外还表明老年女性比年轻女性更接近正常预期寿命。发现双侧性是年龄的递减函数。内侧和外侧肿瘤患者的生存率或远处转移部位没有显著差异。
