Comparison Of Early-Stage High-Grade Serous Primary Fallopian Tube Cancers and Epithelial Ovarian Cancers: A Multicenter Study.

INTRODUCTION

We compared the disease free-survival (DFS) and overall survival (OS) rates of patients with high-grade serous primary fallopian tube cancer (HG-sPFTC) and high-grade serous epithelial ovarian cancer (HG-sEOC).

METHODS

22 early-stage cancer patients (International Federation of Gynecology and Obstetrics (FIGO) stages I-II) with HG-sPFTC were retrospectively evaluated. In addition, 44 control patients diagnosed with HG-sEOC were matched to these patients with respect to tumor stage at diagnosis. All patients underwent complete surgical staging, followed by adjuvant chemotherapy. Kaplan-Meier curves were used to generate survival data.

RESULTS

The mean age of HG-sPFTC patients was 59.4 ± 6.2 years, and that of HG-sEOC patients 55.2 ± 11.0 years (p = 0.002). All patients underwent 6 cycles of platinum-based adjuvant chemotherapy. All operations were optimal. The 5-year DFSs were 77.3% for HG-sPFTC patients and 75% for HG-sEOC patients (p = 1.00).The 5-year OS rates were 81.8% in women with HG-sPFTC and 77.3% in those with HG-sEOC (p = 0.75).

CONCLUSION

The DFS and OS rates of patients with early-stage (FIGO stages I and II) HG-sPFTC and HG-sEOC were similar. The surgical and adjuvant therapy management of these malignancies should be similar.
