Prognostic significance of morphology of tumor and retroperitoneal lymph nodes in epithelial carcinoma of the ovary. I. Correlation with lymph node metastasis.
The prognostic indices based on a morphologic study of tumor and retroperitoneal lymph nodes in 63 patients with epithelial carcinoma of the ovary are reported. The purpose of the study was to identify those variables most frequently related to nodal involvement. The cases in the series consisted of 11 Stage I, 10 Stage II, 34 Stage III, and 8 Stage IV. Histologic distribution was 60.4% serous type, 11.1% mucinous, 6.3% endometrioid, 6.3% clear cell, and 15.9% unclassified. All patients had maximal surgery and selective biopsy of para-aortic and pelvic lymph nodes. The results showed statistically significant variables associated with nodal metastasis in both primary tumor and regional lymph nodes. The indices in primary tumor were grade of tumor, vascular invasion, lymphocytic infiltration, and stromal fibrosis; those in lymph node were type of lymph node reaction, sinus histiocytosis, and fibroblastic proliferation. The nodes with lymphocyte depletion were associated with nodal spread in 81.3% of cases. It is concluded that morphologic study of tumor and lymph node could identify prognostic factors predicting regional nodal metastasis in ovarian carcinoma.
