Serum progesterone at the time of surgery and survival in women with premenopausal operable breast cancer - 1994 - 445-448 - Vol 30A Issues 4 .

Serum progesterone and oestradiol levels have been measured in 210 premenopausal women with operable breast cancer on samples taken within 3 days of tumour excision. There was no relation between oestradiol level and time since last menstrual period, nor any effect of oestradiol value on prognosis. However, serum progesterone levels were related to the phase of the cycle as determined by time since last menstrual period. When divided on a basis of levels > 1.5 ng/ml (luteal phase) and 1.5 ng/ml, it was found that there was no difference in survival between the two groups among 117 axillary node negative cases. However, in the 93 patients with positive axillary nodes, higher progesterone levels were associated with significantly better survival. Thus, serum progesterone levels at the time of surgery may affect the prognosis of premenopausal node positive patients with operable breast cancer
