Therapeutic strategies for non-small cell lung cancer: Experimental models and emerging biomarkers to monitor drug ef6cacies

Clara Bourreau et al.

Summary: Although new targeted therapies have improved the treatment and prognosis of non-small cell lung cancer, they often fail due to primary or acquired resistances. Chemoresistance is a complex process involving various factors. Two approaches that could improve treatment response are developing predictive tools and understanding the influence of the tumor microenvironment. Personalized medicine requires identifying relevant experimental models and biomarkers to combat chemoresistance.

Biomarkers of response to immunotherapy in early stage non-small cell lung cancer

Matthieu Roulleaux Dugage et al.

Summary: Immunotherapy with immune-checkpoint inhibitors (ICIs) has revolutionised the treatment of advanced non-small cell lung cancer (NSCLC). It has shown promising results in early NSCLC, especially with neoadjuvant multimodality approaches. However, biomarkers for predicting response to ICIs in early-stage NSCLC are lacking. PD-L1 expression and tumor mutational burden seem to correlate with better response rates and survival. Other promising approaches include blood-based ratios, microbiota, and baseline intratumoral TCR clonality. Circulating tumor DNA could help in selecting best candidates for adjuvant ICIs and monitoring tumor response.

Update of Incidence, Prevalence, Survival, and Initial Treatment in Patients With Non-Small Cell Lung Cancer in the US

Apar Kishor Ganti et al.

Summary: In this study, the latest US data show a decreasing overall incidence of non-small cell lung cancer (NSCLC) from 2010 to 2017, while the incidence of early stage I disease has risen. NSCLC prevalence has increased, and the estimated 5-year survival rate was found to be 26.4%; a significant proportion of patients aged 65 years or older with stage IV disease were not treated.

Next-Generation Sequencing with Liquid Biopsies from Treatment-Naive Non-Small Cell Lung Carcinoma Patients

Paul Hofman

Summary: Liquid biopsy (LB) has become the only option to detect molecular targets for first-line treatment in treatment-naive NSCLC patients. Despite not being commonly used in diagnosis currently, Next-Generation Sequencing (NGS) shows the most promise for assessing genetic abnormalities.

The Impact of NOTCH Pathway Alteration on Tumor Microenvironment and Clinical Survival of Immune Checkpoint Inhibitors in NSCLC

Xiaohua Li et al.

Summary: High-mutated NOTCH signaling may serve as an independent predictor of prognosis for NSCLC patients receiving ICIs, leading to significantly improved progression-free survival and prolonged overall survival. It is also associated with an inflammatory immune microenvironment, inflammatory expression profile, and enhanced immunogenicity. Further prospective clinical studies and molecular mechanism explorations are necessary for validation.

EGFR Status Assessment for Better Care of Early Stage Non-Small Cell Lung Carcinoma: What Is Changing in the Daily Practice of Pathologists?

Paul Hofman

Summary: The emergence of novel neoadjuvant and/or adjuvant therapies for early stage NSCLC requires the evaluation of predictive biomarkers, with treatment choices currently depending on immunohistochemistry results and EGFR/ALK status. This has led to challenges for clinical and molecular pathology laboratories to adapt to the new landscape.

Perspectives and Issues in the Assessment of SMARCA4 Deficiency in the Management of Lung Cancer Patients

Subasri Armon et al.

Summary: In France in 2020, lung cancers, particularly adenocarcinomas, ranked third in cancer incidence, with a focus on the tumor suppressor gene SMARCA4, impacting younger male smokers. These SMARCA4-deficient adenocarcinomas display aggressive behavior, leading to poor clinical outcomes despite early detection.
