Beyond tertiary cytoreduction in patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer

Background. Primary, secondary, and possibly tertiary surgical cytoreduction in patients with recurrent epithelial ovarian (EOC), fallopian tube (FTC), or primary peritoneal (PPC) cancer appears to be associated with a Survival benefit. The objective of this Study was to assess if cytoreduction of recurrences after tertiary cytoreduction offers any potential benefit in these patients. Methods. We performed a retrospective chart review of all patients with recurrent EOC, FTC, OF PPC who underwent additional cytoreductive procedures after a prior tertiary cytoreduction (quaternary cytoreduction) at our institution between 1991 and 2008. Disease-specific survival (DSS) was calculated from the time of quaternary cytoreduction to last follow-Lip. Univariate analyses were used to analyze Outcomes and to identify potential prognostic factors. Results. A total of 15 patients were identified, of which 7 (47%) have died of disease. All patients had undergone prior optimal secondary and tertiary Surgical cytoreductive procedures. The size of residual disease varied from 0 (in 10 cases/67%) to; 1 cm (in 2 cases, 13%). Residual disease (<= 1 cm vs > 1 cm) and number of recurrence sites (single vs multiple) were found to be significant prognostic factors on Univariate analysis. Conclusions. Cytoreductive Surgery beyond tertiary cytoreduction may be a reasonable option in highly select patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer. especially in the setting of a single site of recurrent disease.
