title: Immunohistochemical study of the expression of HER-2/neu oncogene in ovarian lesions.
abstract: To evaluate the expression of HER-2/neu in various ovarian lesions, 75 cases of ovarian tissues (25 cases of benign lesions and 50 cases of carcinoma) were studied in the department of pathology, Pt. B.D. Sharma PGIMS, Rohtak. Besides conventional H&E staining, representative sections were processed for immunohistochemical staining for HER-2/neu detection. Two (8%) of benign cases were 1+ positive and 19 (38.0%) of malignant lesions were positive for HER-2/neu staining with intensity 1+/2+ in 16 cases (32.0%), 3+ in 2 cases (4%) and 4+ in 1 case (2%). It was observed that HER-2/neu expression was significantly associated with high grade ovarian tumours, however intensity of positivity did not correlate with the grade of tumour.
