Textbook Outcomes Among Patients Undergoing Retroperitoneal Sarcoma Resection

Background/Aim: Recently, the concept of textbook outcome ( TO) has emerged as a novel effort to develop a benchmark that reflects multiple domains of quality. The aims of the current study were to define TO for retroperitoneal sarcoma (RPS), evaluate the relationship of TO with hospital volume and assess the association of TO with overall survival. Patients and Methods: Patients who underwent resection for RPS diagnosed between 2004 and 2015 were identified in the National Cancer Database. The primary outcome was TO that was defined as: hospital length of stay<75th percentile, survival>90 days from surgery, no readmission within 30 days and grossly negative margins. Results: Of the 11,032 patients analyzed, 54.0% had a TO. Among patients who had a TO, 57.8% were treated in high-volume hospitals. Undergoing surgery at high-volume centers was associated with a higher probability of a TO (p=0.009). TO were associated with significantly longer overall survival (p<0.001). In a subgroup analysis with grossly negative margins and no 90-day mortality, the association of TO with improved survival persisted (p<0.001). Conclusion: The concept of TO is a promising tool for measuring patient-level hospital performance and may be useful for identifying important variations in care for patients with RPS.
