Progress in the management of primary and recurrent ovarian carcinomatosis with peritonectomy procedure and HIPEC in a high volume centre

Abstract

Introduction: The treatment of advanced primary or recurrent ephitelial ovarian cancer still remains an open and a critical question. The addition of HIPEC to cytoreductive surgery has shown improving overall survival rates. The aim of our study is to describe the progress in its management in our Unit and what we have learned after more than 350 HIPEC procedures.

Methods: From 1997 to 2016 we conducted a retrospective analysis from a prospective database. We described and analyzed 4 cut-points, 1997–2004, 2009, 2012 and 2016.

Results: From 1997 to September 2016, 358 patients have been operated in our Unit by CRS with peritonectomy procedures plus HIPEC for stage IIIc and IV ovarian cancer. The HIPEC procedures rate was 4,7 HIPEC per years in the first years up to 35 HIPEC/year in last era. Mean age was 56,7 years (28–78). Median PCI was 15,8. (range 3–36). R0-cytoreduction was 95%. Severe morbidity and mortality were observed in 15 % and 2%, respectively. The 3 y OS was 77% in primary and 79% in recurrent ovarian cancer. The stage IV was not a risk factor for survival. R1 cytoreduction and positive lymph nodes were risk factors in multivariate analysis.

Conclusion: The addition of HIPEC to CRS improves overall survival rates for primary and recurrent ovarian cancer. This therapeutic strategy was incorporated twenty years ago for a few teams in the world and today there is an emerging and strong evidence that could consider it as an standard treatment for the ovarian carcinomatosis.
