Analysis of textbook outcomes among patients undergoing resection of retroperitoneal sarcoma: A multi‐institutional analysis of the US Sarcoma Collaborative

Background The novel composite metric textbook outcome (TO) has increasingly been used as a quality indicator but has not been reported among patients undergoing surgical resection for retroperitoneal sarcoma (RPS) using multi‐institutional collaborative data. Methods All patients who underwent resection for RPS between 2000 to 2016 from eight academic institutions were included. TO was defined as a patient with R0/R1 resection that discharged to home and was without transfusion, reoperation, grade ≥2 complications, hospital‐stay >50th percentile, or 90‐day readmission or mortality. Univariate and multivariable analyses were performed. Results Among 627 patients, 56.1% were female and the median age was 59 years. A minority of patients achieved a TO (34.9%). Factors associated with achieving a TO were tumor size
