IMMUNOHISTOCHEMISTRY IN ENDOMETRIAL HYPERPLASIA AND ENDOMETRIAL ADENOCARCINOMA.

AIM: Endometrial hyperplasia is a proliferation of endometrial glands due to the prolonged stimulation with estrogens of the endometrium that occurs in women receiving exogenous estrogens, with anovulatory cycles, or in patients with ovarian tumours with estrogen secretion. MATERIAL AND METHODS: The study performed by the authors included 575 patients with endometrial hyperplasia and 163 patients with endometrial adenocarcinoma admitted to the "Cuza-Voda" Obstetrics and Gynaecology Clinical Hospital of Iasi, between 2005-2007. RESULTS: There were selected, for these immunohistochemistry reactions, 22 cases of simple hyperplasia without atypia, 26 cases of complex hyperplasia without atypia, 23 cases of endometrial adenocarcinoma of endometrioid type, well differentiated, 22 cases of endometrial adenocarcinoma of endometrioid type, moderately differentiated, and 19 cases of non-endometrioid adenocarcinomas represented by nine clear cells and 10 serous endometrial adenocarcinomas. Estrogen receptors have been positive in about 85-90% of the tumour cells of the well-differentiated endometrial adenocarcinomas of endometrioid type (GI). In endometrioid-type endometrial adenocarcinomas moderately differentiated (GII), the estrogen receptors were positive in approximately 70-85% of the tumour cells. CONCLUSIONS: Endometrial hyperplasia, especially complex endometrial hyperplasia with atypia, increase the risk for endometrial adenocarcinoma, and their early detection becomes mandatory under cancer prevention. Well-differentiated endometrioid endome- trial adenocarcinomas were ER and PR-positive, so that the ER expression correlated with the PR expression. Well-differentiated endometrioid endometrial adenocarcinomas (GI) in the studied group also showed a higher content of ER and PR compared to the endometrial moderately-differentiated endometrioid endometrial adenocarcinomas (GII). In nonendometrioid adenocarcinomas, represented by clear-cell endometrial adenocarcinomas, the ER content was reduced and the PR expression was negative. Serous adenocarcinomas failed to show an immunohistochemically expression for ER and PR.

COMPARISONS BETWEEN THE NON-PROLIFERATIVE AND PROLIFERATIVE THERAPY IN FIBROCYSTIC MASTOSIS.

AIM: Fibrocystic mastosis (FCM) is the most frequent benign breast lesion. Most treatments for fibrocystic mastosis are: hormonl, with beneficial results and non-hormonal, with fluctuating results. MATERIAL AND METHODS: A number of 210 cases were studied, which were divided into 7 groups. The study lasted for 9 months and it was carried out on the basis of a personal examination sheet. The following were monitored: age groups, mastodynia, reducing breast nodules, a significant reduction in the volume of the mastosic cysts, reducion of the fibrous tissue, medication tolerance. RESULTS: Mastodynia has declined by 90% in the cases treated with Tamoxifen and Danazol, by 70% in the case of Lynestrenol and Bromocriptine, by 50% in the 15 patients who were given Utrogestan. Knowing the advantages and disadvantages of drugs (contraindications, side effects), age category, breast pain reduction, antiproliferative activity, tolerability, relapse allow us to assess the benefit-risk. Even in those circumstances that remained incompletely clarified for objective reasons, related to the inaccurate/incorrect reporting by the patients, there is a significant difference (p < 0.05) between the frequency of relapses following the treatment with Tamoxifen and the other categories of drugs who were administered. CONCLUSIONS: Our study shows that in the groups that were administered Logest, Utrogestan and Bromocriptine, only antalgic effects were achieved (disappearance or only decrease of mastodynia) and no anti-proliferative effects were obtained. Basically, hormone treatment should be made based on a histopathological examination.
