Expression of Bel-2 in Imprint Smears of Endometrial Carcinoma

摘要

The aims of this study were to determine the expression of Bcl-2 in endometrial adenocarcinomas in imprint smears as an alternative technique rather than the frozen section and to correlate the results with clinicopathologic parameters of primary untreated endometrial cancer patients. One hundred twenty-six patients with endometrial carcinoma were evaluated with samples freshly resected after a total abdominal hysterectomy during a 29-month period. One hundred two cases were type I and 24 type II endometrial adenocarcinomas. Positive expression of Bcl-2 was observed only in type I and in low grade carcinomas. Immunocytochemical findings from Bcl-2 stain, appeared to be a valuable predictor of endometrial cancer diagnosis and postoperative prognosis in most cases in endometrial cytology with imprint smears. Furthermore, positive expression of Bcl-2 was related to morphologic features of less aggressiveness (pathogenetic type I, low-grade, early advanced stage, deep myometrial involvement 1/2 or not) tumors.
