BackgroundPatients with hepatocellular carcinoma (HCC) and microvascular invasion (mVI) have shown dismal postoperative prognosis; however, whether adjuvant transarterial chemoembolization (TACE) can improve their outcomes remains unclear.Materials and MethodsWe retrospectively identified 549 eligible patients to form the crude cohort and adopted propensity score matching method to assemble another cohort of 444 patients with similar baseline characteristics. We assessed the effects of adjuvant TACE by stratified analyses and multivariate Cox analyses in two cohorts.ResultsThere was significant interaction between tumor size and adjuvant TACE with respect to overall survival (OS; p = .006 for interaction). In the matched cohort, patients who received adjuvant TACE showed higher rates of 5-year OS (72.4% vs. 50.9%, p = .005) and 5-year recurrence-free survival (50.5% vs. 36.4%, p = .003) in the tumor 5 cm subgroup, but not in the tumor >5 cm subgroup (32.3% vs. 24.9%, p = .350 and 18.8% vs. 19.7%, p = .180). The independent protective role of adjuvant TACE on OS was observed in patients with tumor 5 cm (adjusted odds ratio [OR] = 0.59, 95% confidence interval [CI] 0.36-0.97) but not in patients with tumor >5 cm (adjusted OR = 1.17, 95% CI 0.84-1.62). The effects of adjuvant TACE did not change materially while the analysis was performed in the crude cohort.ConclusionFor patients with HCC and mVI, adjuvant TACE was associated with improved outcomes, but not for those with tumor >5 cm, according to the current protocol.
