目的：探讨绝经前女性乳腺癌预后与手术时间的关系。方法：以１９８０年至１９８６年我院２６４例可手术绝经前乳腺癌病人为分析对象，初次手术于末次月经第一天始至第１２天为卵泡期组，于末次月经第１２天以后为黄体期组，采用ＢＭＤＰ计算软件进行统计分析。结果：卵泡期组比黄体期组１０年生存率有明显差异（３６２８％比８０７８％Ｐ＝０００１）。两组病例中淋巴结阴性和阳性者１０年生存率比较均有显著性差别。结论：进行乳腺癌的时机化手术是改善绝经前妇女乳腺癌预后的途径之一。
Objective: To investigate the relationship between the prognosis of breast cancer and the operation time in premenopausal women. METHODS: From 1986 to 1986, 264 patients with preoperative breast cancer in pre-menopausal women were analyzed. The first operation was performed in the follicular phase from the first day to the 12th day of the last menstrual period, and the corpus luteum was performed after the 12th day of the last menstrual period. Period group, using BMDP calculation software for statistical analysis. Results: The 10-year survival rate in the follicular phase group was significantly different from that in the corpus luteum phase group (36.8% 28% vs. 80.78% P=0.001). There was a significant difference in the 10-year survival rate between negative and positive lymph nodes in both groups. Conclusion: The timing of breast cancer surgery is one of the ways to improve the prognosis of premenopausal women with breast cancer.
