BACKGROUND: To assess the learning curve for gynecological oncologists in performing upper abdominal surgery for management of patients with advanced epithelial ovarian cancer (EOC).
METHODS: Patients undergoing cytoreductive surgery for stage IIIC and IV EOC that required at leastone surgical procedure in the upper abdomen were divided in three numerically equal groups:group 1, 2 and 3 that underwent surgery between December 2012 and July 2014, August 2014 to March 2016 and April 2016 to March 2018 respectively.
RESULTS: 126 patients were included. The percentage of patients undergoing primary surgery for Group 1, 2 and 3 was 47.6%, 50.0% and 73.8%, respectively (p=0.02). There was significant increase in the percentage of patients undergoing cholecystectomy (p=0.02), resection of disease from porta hepatis (p=0.008), liver capsulectomy (p<0.001), lesser omentectomy (p<0.001) and celiac trunk lymphadenectomy (p<0.001) in the group 3. There was no difference in the percentage of patients undergoing splenectomy, diaphragmatic peritonectomy/resection and gastrectomy. Complete cytoreduction was achieved in 54.8%, 35.7% and 64.3% of patients in group 1, 2 and 3 respectively (p=0.028). There was no significant difference in the occurrence of grade 3-5 complications. Presence of a liver surgeon was required in 9.1%, 5.6% and 0% of cases in group 1, 2 and 3 respectively.
CONCLUSIONS: The results reflect the evolution of surgical skills in the upper abdomen through the increase in the percentage of patients undergoing primary surgery, with the surgical team undertaking more complex procedures, less involvement of other specialties and simultaneously achieving higher rates of complete cytoreduction.
