Background & Aims: Hyperglycemia is associated with an increased risk of gallbladder cancer (GBC), potentially by inhibiting gallbladder motility and inducing prolonged cholestasis. Although intermediate hyperglycemia (or prediabetes) is highly reversible, evidence is lacking about whether prediabetes persistence or remission is associated with an altered GBC risk.

Methods: This nationwide cohort study included 6058,662 adults without diabetes or cancer who underwent national health examinations twice in 2-year intervals between 2009 (S1) and 2011 (S2) and were followed-up until 2018.

Introduction: The most frequently used first-line treatment in patients with advanced hepatocellular carcinoma (HCC) is atezolizumab plus bevacizumab. Upon progression after this treatment, the standard of care in many countries is sorafenib, due to the lack of reimbursement for other drugs. Several randomized trials are currently underway to clarify the best second-line therapy in patients with HCC.

Article Synopsis
  • * A retrospective analysis of 885 HCC patients showed no significant differences in overall survival, time to progression, or disease control rates between viral and nonviral patients treated with the combination therapy.
  • * Common prognostic factors were identified across both groups, but there might be some stronger associations between immunological factors and outcomes specifically in viral patients, while treatment-related toxicities and second-line treatments showed nearly identical results for both etiology subgroups.

Article Synopsis
  • Immune checkpoint inhibitors, particularly pembrolizumab, are being studied as treatment options for advanced gastric cancer (AGC), focusing on their efficacy based on HER2 expression.
  • In a study of 113 AGC patients, 10.6% were HER2-positive, showing significantly better treatment responses, with 50% achieving a partial response compared to just 4.9% of HER2-negative patients.
  • HER2-positive patients also had longer median progression-free survival (5.53 months) compared to HER2-negative patients (1.81 months), indicating that pembrolizumab is more effective for those with HER2-positive tumors.

Background And Aims: Simultaneous inhibition of the TGF-β and programmed cell death 1 ligand 1 pathways provides a potential novel treatment approach. Bintrafusp alfa, a first-in-class bifunctional fusion protein composed of the extracellular domain of TGF-βRII (a TGF-β "trap") fused to a human IgG1 monoclonal antibody blocking programmed cell death 1 ligand 1, was evaluated in patients with advanced HCC.

Approach And Results: In this global, open-label, phase I study (NCT02517398), patients with programmed cell death 1 ligand 1-unselected HCC who failed or were intolerant to ≥1 line of sorafenib received bintrafusp alfa 1200 mg every 2 weeks in a dose-escalation (n = 38) or dose-expansion (n = 68) cohort until confirmed progression, unacceptable toxicity, or trial withdrawal.

Regorafenib has anti-tumor activity in patients with unresectable hepatocellular carcinoma (uHCC) with potential immunomodulatory effects, suggesting that its combination with immune checkpoint inhibitor may have clinically meaningful benefits in patients with uHCC. The multicenter, single-arm, phase 2 RENOBATE trial tested regorafenib-nivolumab as front-line treatment for uHCC. Forty-two patients received nivolumab 480 mg every 4 weeks and regorafenib 80 mg daily (3-weeks-on/1-week-off schedule).
