Background
Traditional metrics may inadequately represent rates of attaining optimal oncologic care. We evaluated a composite “textbook oncologic outcome” (TOO) to assess the incidence of achieving an “optimal” clinical result after colon adenocarcinoma (CA) resection.
Methods
The National Cancer Database (NCDB) was queried to identify patients undergoing colectomy for non-metastatic CA between 2010 and 2015. TOO was defined as a margin negative resection with an AJCC compliant lymph node evaluation, no prolonged length of stay (LOS) or 30-day readmission/mortality, as well as receipt of stage appropriate adjuvant chemotherapy.
Results
Among 170,120 patients who underwent colectomy at 1315 hospitals, 93,204 (54.8%) achieved TOO with large variations observed among facilities. While certain factors were achieved nearly universally (R0 margin, 95.6%; no 30-day mortality, 97.2%), avoidance of prolonged LOS (77.3%) and appropriate adjuvant chemotherapy (83.0%) were achieved less consistently. On multivariable analysis, Black race/ethnicity (OR 0.82, 95% CI 0.80–0.85), Medicaid insurance (OR 0.64, 0.61–0.68), and low-volume facility (< 50/year) (OR 0.83, 0.77–0.89) were associated with decreased likelihood of TOO. Achievement of TOO was associated with improved long-term survival (HR 0.45; 95% CI 0.44–0.46).
Conclusions
Roughly one-half of patients undergoing resection of CA achieved an optimal clinical outcome. TOO may be a more useful quality metric to assess patient-centric composite outcomes following surgical procedures.
