Abstract

Overall survival and relapse free survival (RFS) were studied in 547 patients according to the presence of prolactin receptors (PRL-R), either free or total (after 3 M MgCl2 desaturation). All these patients were surgically treated for locoregional disease in the same institution between 1978 and 1984.

In actuarial survival studies, RFS was higher in total PRL-R positive patients in the whole population (P less than 0.02).

When the population was divided into two groups, according to either the presence or the absence of node metastasis or the presence or absence of estradiol receptor, the higher RFS was restricted to node positive (P less than 0.001) and to estradiol receptor positive patients (P less than 0.01).

The Cox analysis on RFS showed that free PRL-R alone was a significant prognostic factor in estradiol receptor positive patients; total PRL-R alone was never significant; when considered together with steroid receptors, free as well as total PRL-Rs were significant prognostic factors in some subgroups of patients.
