The role of factor XIII in surgery for advanced stage of epithelial ovarian cancer.

ABSTRACT

INTRODUCTION: Hereditary factor (F) XIII-deficiency is a known risk factor for postoperative complications, but data of acquired FXIII-deficiency in malignancies are limited. Therefore, we evaluated the role of acquired FXIII-deficiency in surgery for advanced epithelial ovarian cancer (EOC). MATERIALS AND METHODS: We performed a retrospective analysis of patients with known serum FXIII status and treatment between 2011 and 2018 at our center. We defined cohorts according to FXIII with values > 75% as normal (group A), 55-75% as reduced (group B) and < 55% as low (group C). Complications were classified according to the Clavien-Dindo Classification, class III-V complications were defined as severe. RESULTS: 347 patients with EOC were identified. 180 patients (51.2%) were in group A, 82 patients (23.6%) in group B, and 85 patients (24.4%) in group C. Lower levels of FXIII were associated with higher amount of ascites, FIGO IV, high grade serous histology, low albumin, and higher CA-125 levels. Regarding intraoperative variables, low FXIII was associated with longer duration of surgery, higher blood loss, higher surgical complexity score/number of bowel anastomosis and a higher probability for macroscopic residual disease. The risk of severe complications in group A was 12.2%, 24.4% in group B, and 31.8% in group C. In a multivariate model, low FXIII (OR 2.8), > 1 bowel anastomosis (OR 2.7), age-adjusted Charlson comorbidity index ≥ 4 (OR 3.6) and a longer duration of surgery (> 285 min.) were significant predictive factors for severe complications. CONCLUSION: FXIII is associated with tumor and treatment burden. A low level of FXIII is associated with postoperative complications. The knowledge about the presurgical serum FXIII-level might be helpful to plan the treatment strategy.
