Textbook outcome and textbook oncological outcome in esophagogastric cancer surgery - A systematic scoping review

Quality assurance in esophagogastric surgery, particularly in an oncological context, is important, especially as long-term survival is highly affected by the short-term outcomes. Textbook Outcome (TO) and Textbook Oncological Outcome (TOO) serve as multidimensional metrics to assess surgical quality by evaluating various perioperative factors, as well as oncological outcomes. TO and TOO have been associated with improved long-term survival.

This study aimed to examine the incidence of, and the definitions of TO and TOO used in esophagogastric oncological surgery.

This systematic scoping review followed the PRISMA 2020 guidelines and the PRISMA scoping review extension. The AMSTAR-2 was used to rate the review. A comprehensive systematic search was performed in Medline, Embase, and Web of Science and results were screened through Covidence. Quality assessment was conducted using the Newcastle-Ottawa scale.

A total of 55 observational cohort studies on esophagogastric cancer surgery were included. A total of 245,075 patients was included in the assessment of the achievement of TO and TOO. The rate of TO achievement ranged from 20.4 to 84.2 %, while the rate of TOO achievement ranged from 21.3 to 57.6 %. TO and TOO definitions varied widely, combining a median of nine (range: 4-11) parameters with a total of 45 different parameters being reported.

This systematic scoping review showed significant variations in incidence and in the definitions used for TO and TOO in esophagogastric cancer surgery between the included studies. This highlights the importance of standardizing the definitions of TO and TOO.
