Hepatocellular Carcinoma

Key clinical point: Among patients with hepatocellular carcinoma (HCC), an “ideal candidate for ablation” per the Barcelona Clinic Liver Cancer (BCLC) staging system may not be ideal for microwave ablation (MWA); however, patients with BCLC-0 disease may comprise the optimal population for MWA.

Major finding: Liver resection (LRE) vs MWA led to a significantly longer recurrence-free survival in the overall population (P = .025) and patients with BCLC-A disease (P = .003) but not in those with BCLC-0 disease (P = .270), in addition to similar overall survival (P = .976) and post-procedure-related complication rates (P = 1.00) in BCLC-0 patients.

Study details: This retrospective study included patients with HCC who met the criteria of “ideal candidates for ablation” per the BCLC staging system and propensity score-matched those receiving MWA and LRE (overall population 140 pairs; BCLC-0 disease 35 pairs; BCLC-A disease 99 pairs).

Key clinical point: Compared with transcatheter arterial chemoembolization (TACE) followed by radiotherapy (RT), administering RT before TACE leads to better survival outcomes in patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT).

Major finding: Patients who received RT+TACE vs TACE+RT had significantly longer median progression-free survival (6.6 vs 4.2 months; hazard ratio [HR] 0.66; P = .030), with the prolongation of median overall survival being marginally significant (15.4 vs 11.5 months; HR 0.68; P = .054).

Study details: Findings are from a randomized controlled study including 120 patients with unresectable HCC and PVTT who were randomly assigned (1:1) to receive RT+TACE or TACE+RT.

Key clinical point: The combination of alpha-fetoprotein (AFP) and carbohydrate antigen 19-9 (CA19-9) may effectively predict the prognosis of patients with hepatocellular carcinoma (HCC) after radical hepatectomy.

Major finding: The 5-year overall and recurrence-free survival rates were significantly lower among patients with high preoperative serum AFP and CA19-9 levels than among those with high serum AFP or CA19-9 levels (P = .022 and P = .004, respectively) and those with low serum AFP and CA19-9 levels (both P < .001).

Key clinical point: Highly elevated antidrug antibody (ADA) levels (≥1,000 ng/mL) at 3 weeks (cycle 2 day 1 [C2D1]) may be associated with poor clinical outcomes after atezolizumab/bevacizumab (Atezo/Bev) treatment in patients with advanced hepatocellular carcinoma (HCC).

Major finding: In both discovery cohort (DC) and validation cohort (VC), patients with high vs low ADA levels at C2D1 had worse progression-free survival (DC: hazard ratio [HR] 2.84; P = .005; VC: HR 2.52; P = .006) and overall survival (DC: HR 3.30; P = .003; VC: HR 5.81; P = .001).

Study details: This prospective cohort study included 132 patients with advanced HCC treated with first-line Atezo/Bev (DC n = 50; VC n = 82).

Key clinical point: Highly elevated antidrug antibody (ADA) levels (≥1,000 ng/mL) at 3 weeks (cycle 2 day 1 [C2D1]) may be associated with poor clinical outcomes after atezolizumab/bevacizumab (Atezo/Bev) treatment in patients with advanced hepatocellular carcinoma (HCC).

Major finding: In both discovery cohort (DC) and validation cohort (VC), patients with high vs low ADA levels at C2D1 had worse progression-free survival (DC: hazard ratio [HR] 2.84; P = .005; VC: HR 2.52; P = .006) and overall survival (DC: HR 3.30; P = .003; VC: HR 5.81; P = .001).

Study details: This prospective cohort study included 132 patients with advanced HCC treated with first-line Atezo/Bev (DC n = 50; VC n = 82).

Disclosures: This study was sponsored by a National Research Foundation of Korea grant funded by the Korean government and others. Some authors reported serving as advisors for or receiving personal fees or grants from various sources.
