Decoding KRAS mutation in non-small cell lung cancer patients receiving immunotherapy: A retrospective institutional comparison and literature review.

Introduction: KRAS mutation the most common molecular alteration in advanced non-small cell lung cancer (NSCLC) and is associated with an unfavourable prognosis, largely due to the lack of targeted therapeutic options for the majority of the KRAS mutated isoforms. The landscape of NSCLC treatment has expanded with the introduction of immune checkpoint inhibitors (ICIs). Nonetheless, data regarding the efficacy of ICI in NSCLC patients harbouring KRAS mutations are conflicting.

Spondyloarthritis and Risk of Malignancy: A Narrative Review on a Still Controversial Issue.

Current literature regarding cancer risk in rheumatic and musculoskeletal diseases (RMDs) is particularly poor and controversial, even though the incidence of malignancy in some patients with RMDs is considered to be increased compared with the general population. Malignancy may be a major comorbidity in subjects with spondyloarthritis (SpA) as the result of multifactorial mechanisms, from disease pathogenesis to the iatrogenic effect of immunomodulating drugs. Several recommendations for screening and management of cancer risk have been developed in recent years with the aim of improving the different outcomes in these patients.

Early downmodulation of tumor glycolysis predicts response to fasting-mimicking diet in triple-negative breast cancer patients.

In preclinical experiments, cyclic fasting-mimicking diets (FMDs) showed broad anticancer effects in combination with chemotherapy. Among different tumor types, triple-negative breast cancer (TNBC) is exquisitely sensitive to FMD. However, the antitumor activity and efficacy of cyclic FMD in TNBC patients remain unclear.

Exploring Genomic Biomarkers for Pembrolizumab Response: A Real-World Approach and Patient Similarity Network Analysis Reveal DNA Response and Repair Gene Mutations as a Signature.

: Single-agent immune checkpoint inhibitor (IO) therapy is the standard for non-oncogene-addicted advanced non-small cell lung cancer (aNSCLC) with PD-L1 tumor proportion score ≥ 50%. Smoking-induced harm generates high tumor mutation burden (H-TMB) in smoking patients (S-pts), while never-smoking patients (NS-pts) typically have low TMB (L-TMB) and are unresponsive to IO. However, the molecular characterization of NS-pts with H-TMB remains unclear.
