Preferred timing from one of the studies:
surgery between days 0 and 2 or from 13 days after their last menstrual period is prefered.
We studied this controversial issue by examining the serum estradiol and progesterone levels of 38 premenopausal patients with primary breast cancer, and by analyzing data on 100 premenopausal patients treated for primary breast cancer. The survival of 31 patients who had undergone initial surgery between days 3 and 12 after their last menstrual period (group E) was compared with that of 69 patients who had undergone surgery between days 0 and 2 or from 13 days after their last menstrual period (group P). The overall survival of group E was significantly worse than that of group P (P=0.049). This difference was especially notable in patients with node-positive tumors or tumors larger than 2 cm in size; however there was no significant difference in disease-free survival between the two groups
