[Immunohistochemical markers expression in hysteroscopy and hysterectomy specimens from endometrial cancer patients: comparison].

To assess the immunohistochemical expression of p53, bcl-2, c-erbB-2, Ki-67, estrogen (ER) and progesterone receptors (PR), MMP-7, MMP-26 in samplex from diagnostic hysteroscopy and therapeutic hysterectomy in endometrial cancer patients.Experimental prospective study.Department of Obstetrics and Gynecology, Institute of Human Genetics, Department of Pathology, Palacky University Medical School and University Hospital, Olomouc.We studied 43 cases of primary untreated endometrial carcinoma in which the grade and immunomarkers assessed by histoscore were investigated in specimens obtained at hysteroscopy and hysterectomy.Based on hysterosopy, 31 (72.1%) patients were classified as G1, G2 7 (16.3%) and G3 5 (11.6%) respective. In grade 1 the concordance rate was 77.4% of cases, in grade 2 it was in 14.3% of cases and in grade 3 it was in 80.0% of cases. In hysterosocpy samples the p53 expression was found in 23 (53.5%), bcl-2 in 37 (86.0%), c-erbB-2 in 20 (46.5%), Ki-67 in 29 (67.4%), ER in 37 (86.0%), PR in 36 (83.7%), MMP-7 in 25 (58.1%) and MMP-26 in 23 (53.5%) cases. Expression in hysterectomy specimens was p53 positive in 13 (30.2%), bcl-2 positive in 33 (76.7%), c-erbB-2 positive in 24 (55.8%), Ki-67 positive in 25 (58.1%), ER positive in 36 (83.7%), PR positive in 40 (93.0%), MMP-7 positive in 27 (62.8%) and MMP-26 positive in 23 (53.5%) of total 43 cases.We found high concordance in expression of p53, bcl-2, PR and MMP-7 in hysteroscopy and hysterectomy samples which could be of importance for therapeutic algorithm in endometrial cancer patients.
