Abstract
A review of literature comparing the survival of patients with clear cell carcinoma of the ovary to patients with serous carcinoma reveals divided opinions. No studies of statistical significance have demonstrated worse survival in a cohort of patients with clear cell carcinoma matched stage for stage with patients with serous carcinoma of the ovary. The purpose of this study was to compare survival in a cohort of clear cell carcinoma patients to a cohort of serous carcinoma patients matched for stage, age, treatment, and cytoreduction. All cases of clear cell carcinoma and serous carcinoma of the ovary operated on by the gynecology oncology service from January 1, 1981 to December 31, 1989 were evaluated for patient age, length of survival and level of primary cytoreduction, as well as FIGO stage and histology. Twenty-two patients with clear cell carcinoma found in the years noted were compared to a cohort of 22 patients with serous carcinoma matched for stage (I, 18.2%; II, 9.1%; III, 63.6%; IV, 9.1%), age (clear cell carcinoma 58 years, serous carcinoma 60 years (p = 0.330)), and level of primary cytoreduction (optimal in 63.6% of both clear cell carcinoma and serous carcinoma cohorts and non-optimal in 36.4% of both groups). Survival in the clear cell carcinoma cohort (16 months) was worse than in the serous carcinoma cohort (36 months) (p = 0.045). Patients with clear cell carcinoma have a significantly worse prognosis than patients with serous carcinoma when matched for age, stage, and level of primary cytoreduction.
