Purpose: Recent research (Li et al. 2021) suggests an upregulated expression and activation of H1 receptors on macrophages in the tumor microenvironment, and concomitant H1-antihistamine use is associated with improved overall survival in patients with lung and skin cancers receiving immunotherapy. Therefore, we retrospectively evaluated the impacts of H1-antihistamine use in cancer patients during immunotherapy.

Article Synopsis
  • Lung cancer is the most common type of cancer in the Asia-Pacific region, with non-small cell lung cancer (NSCLC) making up about 85% of cases, and a significant mutation rate of 40-60% in Asian patients with lung adenocarcinoma.
  • Third-generation EGFR tyrosine kinase inhibitors (EGFR-TKIs) have improved treatment for NSCLC with mutations, but managing resistance to these drugs is still a major issue with no standardized guidelines.
  • A set of recommendations has been developed, integrating international guidelines and regional clinical experiences, to help healthcare providers classify resistance, conduct clinical testing, and devise treatment strategies for patients struggling with resistance to third-generation EGFR-TKIs.

Lung cancer, the leading cause of cancer-related deaths globally, remains a pressing health issue despite significant medical advances. The New York Lung Cancer Foundation brought together experts from academia, the pharmaceutical and biotech industries as well as organizational leaders and patient advocates, to thoroughly examine the current state of lung cancer diagnosis, treatment, and research. The goal was to identify areas where our understanding is incomplete and to develop collaborative public health and scientific strategies to generate better patient outcomes, as highlighted in our "Calls to Action.

SMARCA4 mutation has emerged as a marker of poor prognosis in lung cancer and has potential predictive value in cancer treatment, but recommendations for which patients require its investigation are lacking. We comprehensively studied SMARCA4 alterations and the clinicopathological significance in a large cohort of immunohistochemically-subtyped non-small cell lung cancer (NSCLC). A total of 1416 patients was studied for the presence of SMARCA4 deficiency by immunohistochemistry (IHC).

The Baveno VII criteria are used in patients with liver cirrhosis to predict high-risk varices in patients with liver cirrhosis. Yet its use in patients with advanced hepatocellular carcinoma (HCC) has not been validated. HCC alone is accompanied with a higher variceal bleeding risk due to its association with liver cirrhosis and portal vein thrombosis.

Inflammation in the tumor microenvironment is a complicit and known carcinogenesis driver. Inhibition of IL-1β, one of the most abundant and influential cytokines in the tumor microenvironment, may enhance the efficacy of PD-1. In a analysis of phase III cardiovascular CANTOS trial, canakinumab, a monoclonal anti-IL-1β antibody, significantly reduced lung cancer incidence.

Purpose: Biomarkers on the basis of tumor-infiltrating lymphocytes (TIL) are potentially valuable in predicting the effectiveness of immune checkpoint inhibitors (ICI). However, clinical application remains challenging because of methodologic limitations and laborious process involved in spatial analysis of TIL distribution in whole-slide images (WSI).

Methods: We have developed an artificial intelligence (AI)-powered WSI analyzer of TIL in the tumor microenvironment that can define three immune phenotypes (IPs): inflamed, immune-excluded, and immune-desert.

Article Synopsis
  • - The IMpower150 study investigated the effectiveness of atezolizumab and/or bevacizumab combined with carboplatin/paclitaxel chemotherapy in patients with non-squamous non-small cell lung cancer (NSCLC), focusing on the impact of specific mutations.
  • - Results showed that patients with certain mutations experienced better overall survival (OS) and progression-free survival (PFS) with the combination therapy (ABCP) compared to chemotherapy alone (BCP), particularly in mutation-evaluable groups.
  • - The study concluded that specific mutations are associated with poorer outcomes, highlighting the importance of mutation status in guiding treatment decisions, with ABCP showing superior efficacy compared to other treatment regimens in certain patient subgroups. *

Objectives: To compare efficacy and safety of dacomitinib versus gefitinib as first-line therapy for EGFR mutation-positive advanced NSCLC in Asian patients enrolled in the ongoing ARCHER 1050 trial.

Materials And Methods: In this ongoing, randomized, open-label, phase 3 trial (NCT01774721), eligible patients with newly diagnosed advanced EGFR mutation-positive NSCLC were randomized (1:1) to receive oral dacomitinib 45 mg/day or oral gefitinib 250 mg/day. Randomization, by a central computer system, was stratified by race and EGFR mutation type (exon 19 deletion mutation/exon 21 L858R substitution mutation).

Canakinumab is a human IgGκ monoclonal antibody, with high affinity and specificity for IL-1β. The Canakinumab Anti-Inflammatory Thrombosis Outcome Study (CANTOS) trial, evaluating canakinumab for cardiovascular disease, provided the first signal of the potential of IL-1β inhibition on lung cancer incidence reduction. Here, we describe the rationale and design for CANOPY-N, a randomized Phase II trial evaluating IL-1β inhibition with or without immune checkpoint inhibition as neoadjuvant treatment in patients with non-small-cell lung cancer.

Introduction: Immunotherapy has dramatically improved the survival of patients with advanced or metastatic malignancies. Recent studies suggest that immunotherapy may increase the risk of hepatitis, whereas it may also induce functional cure of chronic hepatitis B virus (HBV) infection. We evaluated the incidence of hepatitis flare, HBV reactivation, hepatitis B surface antigen (HBsAg) seroclearance or seroreversion in patients with current or past HBV infection who had received immunotherapy.

Non-small cell lung cancer (NSCLC) harboring epidermal growth receptor (EGFR) mutation has distinct genomic characteristics. Introduction of systemic treatments that specifically targeted actionable EGFR mutations has changed the therapeutic paradigm in this group of patients. Moreover, newer generations of EGFR tyrosine-kinase inhibitors (EGFR-TKIs) with superior pharmacokinetics and pharmacodynamics properties such as dacomitinib and osimertinib, when used in the front-line setting, have shown more favorable treatment outcomes than first-generation EGFR-TKIs.

Introduction: The phase III randomized PROFILE 1014 study demonstrated superiority of crizotinib to first-line chemotherapy in prolonging progression-free survival (PFS) in previously untreated patients with ALK receptor tyrosine kinase gene (ALK)-positive advanced nonsquamous NSCLC. This result was consistent with that in the smaller subset of East Asian patients in PROFILE 1014. The subsequent study reported here prospectively evaluated crizotinib in a larger East Asian patient population.
