Variations in Textbook Oncologic Outcomes After Curative-Intent Resection: Early Versus Intermediate Hepatocellular Carcinoma Based on Barcelona Clinic Liver Cancer Criteria and Child-Pugh Classification.

ABSTRACT

BACKGROUND: The impact of early versus intermediate hepatocellular carcinoma (HCC) on short-term "optimal" outcomes remains ill-defined. This study sought to define the incidence of textbook oncologic outcomes (TOO), as well as to identify factors associated with TOO among patients with early versus intermediate HCC. METHODS: Patients who underwent curative-intent liver resection for HCC (1998-2020) were identified from a multi-institutional database. Textbook oncologic outcome (TOO) was defined as negative surgical margins, no return to the operating room, no extended hospital stay, no severe complications, and no 90-day mortality or readmission. Patients were stratified as early HCC (BCLC 0 or BCLC A/Child-Pugh A) or intermediate HCC (BCLC A/Child-Pugh B or BCLC B). Multivariate logistic regression analysis was used to assess factors associated with TOO. RESULTS: Among 1383 patients, the overall incidence of TOO was 69.0%. Patients with intermediate HCC were less likely to achieve a TOO (early [71.6 %] vs. intermediate [60.1%]; p < 0.001). On multivariate analysis, factors associated with decreased odds of a TOO were high tumor burden (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.33-1.00), high aspartate transaminase-platelet ratio index (APRI) (OR, 0.46; 95% CI, 0.30-0.70), Charlson Comorbidity Index (CCI) greater than 3 (OR, 0.67; 95% CI, 0.49-0.91), major liver resection (OR, 0.68; 95% CI, 0.52-0.90), and intermediate HCC (OR, 0.68; 95% CI, 0.50-0.93) (all p < 0.05). Notably, although high APRI, CCI greater than 3, and major liver resection contributed to lower odds of a TOO in early HCC, the only factor that adversely impacted TOO in intermediate HCC was high tumor burden. CONCLUSIONS: Patients with intermediate HCC and early HCC patients with liver dysfunction, comorbidities, or an extensive resection were less likely to achieve an "optimal" postoperative outcome.
