Abstract
OBJECTIVE: To compare the surgical and histological outcomes of diaphragmatic peritonectomy vs. full thickness resection with pleurectomy during Visceral-Peritoneal Debulking. METHODS: Service evaluation protocol (Trust number 3265). All patients with stage IIIC-IV ovarian cancer who had diaphragmatic surgery between April 2009 and November 2013 were included. Clinical notes and histology reports were reviewed. Additional histology sections were undertaken. Patients were divided in Groups 1 (peritonectomy) and 2 (pleurectomy). The outcomes of interest were: surgical (intra- and post-operative morbidity, pulmonary morbidity, mortality, rate of complete resection) and histological (rate of diaphragmatic peritoneum, muscle and pleural involvement, rate of microscopic diaphragmatic free margins). RESULTS: Sixty four patients had diaphragmatic peritonectomy (Group 1), 36 patients full thickness diaphragmatic resection with pleurectomy (Group 2). There was no significant difference in the rate of mortality (3% in both groups), overall intra- and post-operative morbidity (32.8% vs. 38.8%), pulmonary morbidity (9.3% vs. 19%, P=0.14). Histology showed tumor invasion in the diaphragmatic peritoneum (96%), muscle (28%) and pleura (19.4%). Microscopic free margins were seen in 86% vs. 92% in Groups 1 and 2. CONCLUSIONS: Our study demonstrated that, in patients with ovarian cancer, diaphragmatic involvement extends to the muscle in almost 30% and to the pleura in 20% of the patients. Overall and specific morbidity was not significantly different when comparing peritonectomy vs. pleurectomy.
