Main Findings
Proficiency-based progression training can be safely used to teach RAL surgery for women with endometrial cancer. Training cases were less obese than non-training cases, but were comparable in age, performance status and comorbidities. No influence of PBP training on intra- and post-operative complications, blood transfusions, readmissions < 30 days, return to theatre rates and median 5-year disease-free and disease-specific survival in RAL surgery for endometrial cancer was found.
