OBJECTIVES: The aim of this study was to estimate the survival impact of adjuvant paclitaxel and carboplatin (TC) compared to cisplatin (CDDP)-based chemotherapies for early-stage ovarian clear-cell carcinoma (CCC).
METHODS: Clinicopathologic information on 99 stage I-II CCC patients was obtained between 1987 and 2005. All patients underwent complete surgical staging including systemic lymphadenectomy, followed by TC or various CDDP-based regimens. In the present study, only CCC patients with no residual tumor were enrolled.
RESULTS: The median age was 53 years and ranged from 30 to 69 years. Fifty-three (53.5%) patients received TC and 46 (46.5%) patients underwent various CDDP-based chemotherapies after initial surgery. Five-year progression-free survival (PFS) rates of TC and various CDDP groups were 66.5 and 75.8%, respectively (n.s., p = 0.933). In addition, 5-year overall survival (OS) rates of TC and various CDDP groups were 82.4 and 82.3%, respectively (n.s., p = 0.583). In multivariate analyses of OS and PFS, the regimen of chemotherapywas not a significant prognostic factor (OS, p = 0.502; PFS, p = 0.977.
CONCLUSIONS: In our current examination of the long-term survival of early-stage CCC patients, we did not identify a superiority of TC over various CDDP-based regimens as frontline adjuvant chemotherapy.
