Objective: Patients with ovarian cancer may have occult metastasis at the time of surgery. Our purpose was to determine the prevalence and sites of occult metastasis in epithelial ovarian cancer grossly confined to the ovary and examine the significance of routine omentectomy and peritoneal biopsies as part of a comprehensive staging procedure.
Study design: Data were retrospectively abstracted from patients presenting to University of Texas Southwestern Medical Center Hospitals from 1993 through 2009 with ovarian cancer without gross spread beyond the ovary who underwent comprehensive surgical staging.
Results: A total of 86 patients with ovarian cancer grossly confined to the ovary who underwent complete surgical staging were identified. Of patients, 29% were upstaged following comprehensive surgical staging; 6% had metastatic disease in uterus and/or fallopian tubes, 6% in lymph nodes, and 17% in peritoneal, omental, or adhesion biopsies.
Conclusion: Patients with epithelial ovarian cancer should continue to undergo comprehensive surgical staging, since it identifies occult metastasis in a significant number of patients.
