本院自１９８５年以来，开展了乳腺癌保留乳房治疗的研究，至１９９３年１２月共治疗４５例，其中Ⅰ期２２例，Ⅱ期２３例。经３年、５年随访观察，复发率为７．３％（３／４１），其中１例单纯乳腺复发经行乳房切除补救，５年后仍无瘤生存。乳腺复发伴肝转移、乳腺复发伴肺转移各１例，分别于３年、４年死亡。３年无瘤生存率为９５．１％（３９／４１），５年为９３．３％（２８／３０）。作者认为：Ⅰ、Ⅱ期乳腺癌患者中，部分病例选择性行保留乳房治疗的方案是可行的。 Since 1985, this hospital has carried out research on breast cancer preservation therapy. By December 1993, a total of 45 cases had been treated, of which 22 were in stage I and 23 in stage II. After 3 years and 5 years of follow-up, the recurrence rate was 7.3% (3/41). One case of breast recurrence was remedied by mastectomy, and the tumor survived 5 years later. Breast recurrence with liver metastases, breast recurrence with lung metastasis in 1 case, respectively, died in 3 or 4 years. The 3-year disease-free survival rate was 95.1% (39/41) and 53.3% (28/30). The authors believe that in patients with stage I and stage II breast cancer, it is feasible to selectively maintain breast treatment in some cases.
