Assessment of Hospital Volume in the Surgical Management of Endometrial and Ovarian Cancer: A Polish Population-Based Study.

BACKGROUND Surgery is a cornerstone in management of ovarian and endometrial cancer. The European Society of Gynecological Oncology introduced quality indicators to improve management of these cancers. The optimal annual number of surgeries per unit was established for high-quality surgical treatment. MATERIAL AND METHODS The database of the National Health Fund on surgical management of endometrial and ovarian cancer was analyzed. Patients treated between 2017 and 2020 were included. Departments where patients underwent surgery were divided according to number of surgeries performed per year in endometrial cancer: ≥80, 79-50, 49-20, 19-0; and ovarian cancer: ≥100, 99-50, 49-20, 19-0. Optimal number of surgeries per center was defined as at least 100 and 80 surgeries per year in ovarian and endometrial cancer, respectively. RESULTS Totally, there were 22 325 surgeries in 316 units and 10 381 surgeries in 251 units due to endometrial and ovarian cancer, respectively. Most surgeries in endometrial cancer (n=15 077; 67.5%) and ovarian cancer (n=9642; 92.88%) were performed in departments that did not meet optimal criteria in number of surgeries. Between 2017 and 2019, an increasing trend in number of surgeries per year in endometrial and ovarian cancer was found. In 2020, there was a decrease in the number of surgeries by 7.8% (n=453) and 8.6% (n=234) in endometrial and ovarian cancer, respectively. CONCLUSIONS In Poland, surgical treatment of ovarian and endometrial cancer is decentralized. Most cancer patients underwent surgery in low-volume general gynecologic departments. The COVID-19 pandemic impaired cancer management, leading to a decreased number of surgeries.
