Plasma progesterone concentration in women with and without adenocarcinoma of the endometrium.
In the search for the postulated but elusive "estrogenic bias" in patients developing endometrial cancer, several authors have suggested lack of progesterone as the common denominator. In this study 21 patients at the time of diagnosis of Stage I disease are compared to stringently matched healthy control subjects. No significant difference was found in plasma progesterone concentrations between the two groups. These results, in conjunction with other calculated estrogenic indices based on these patients, provide no evidence of lack of progesterone at the onset of clinical disease. However, the effects of long-term progesterone lack related to chronic anovulation are not excluded by these findings.
