title: Ovarian clear cell adenocarcinoma.
abstract: The clinical and pathologic features of 29 cases of ovarian clear cell adenocarcinoma (OCCA) were studied to evaluate outcome and potential predictors of survival. Patients' ages ranged from 30 to 89 years (median, 54 years). The study group, using the FIGO classification, consisted of 10 Stage I, 5 Stage II, 7 Stage III, 5 Stage IV, and 2 unstaged patients. Previous or concurrent endometriosis was noted in 45% of patients. Three patients (10.3%) had hypercalcemia. Only stage and the presence of macroscopic residual disease had a statistically significant association with survival. Stage I and II patients experienced a survival similar to a group of 305 patients with adenocarcinomas of non-clear cell type in our ovarian cancer registry with the exception of the very poor survival among Stage IC OCCA patients. Patients with Stage III and IV OCCA had a worse survival than non-OCCA registry patients of similar stage. Few objective responses to adjuvant chemotherapy could be demonstrated in these high-stage OCCA patients. Further study of postoperative adjuvant therapies is warranted.
