[Correlation between receptor status and results of treatment in endometrial carcinoma]

In the course of immunohistochemical assay of estrogen (ER), progesterone (PR) and oncoprotein HER-2/neu receptors, PR+ expression was identified in 52% of 50 patients with endometrial carcinoma. A direct correlation between ER and PR levels (i = 0.7) was established (ER+/PR(+)--26.0%; ER-/PR(-)--42.0%; ER-/PR(+)--26.0%; ER+/PR(-)--6.0%). In the ER+/PR+ and--ER-/PR+ groups, adjuvant therapy with progestins was carried out (3-year-survival--95.3% (p < 0.05)); recurrence rate--8.0%. Inverse correlations were characteristic of ER and HER-2/neu (i = -0.4) and PR and HER-2/neu (i = -0.114). Adjuvant polychemotherapy was administered in 12.2% of cases of HER-2/neu over-expression. That group revealed a drop in 3-year survival from 85.5 to 41.7% and relapse in half of the patients.
