Background: Neoadjuvant immune checkpoint inhibitors (ICIs) have improved survival outcomes compared with chemotherapy in resectable non-small cell lung cancer (NSCLC). However, the impact of actionable genomic alterations (AGAs) on the efficacy of neoadjuvant ICIs remains unclear. We report the influence of AGAs on treatment failure (TF) in patients with resectable NSCLC treated with neoadjuvant ICIs.

Article Synopsis
  • Dual immune checkpoint blockade (ICB) using CTLA4 and PD-(L)1 inhibitors shows improved anti-tumor effectiveness and immune toxicity compared to PD-(L)1 inhibitors alone in advanced non-small-cell lung cancer (NSCLC) patients.
  • Patients with mutations in STK11 and/or KEAP1 genes benefit more from the combination treatment compared to those receiving only PD-(L)1 inhibitors, as shown in the POSEIDON trial.
  • The loss of KEAP1 serves as a strong predictor for the success of dual ICB, as it leads to a more favorable outcome by changing the tumor's immune environment to better engage CD4 and CD8 T cells for anti-tumor activity. *

Article Synopsis
  • Scientists found that using two medications together, one that stops cancer and another that helps blood vessels, can help people with a certain type of lung cancer live longer without their cancer getting worse.
  • They ran a study (called the RAMOSE trial) comparing one medication plus the blood vessel helper to just the medication alone.
  • The results showed that people taking both medications had better outcomes, living longer without cancer progression, even though both groups experienced side effects from the treatments.

T cell receptor (TCR) T cell therapies target tumor antigens in a human leukocyte antigen (HLA)-restricted manner. Biomarker-defined therapies require validation of assays suitable for determination of patient eligibility. For clinical trials evaluating TCR T cell therapies targeting melanoma-associated antigen A4 (MAGE-A4), screening in studies NCT02636855 and NCT04044768 assesses patient eligibility based on: (1) high-resolution HLA typing and (2) tumor MAGE-A4 testing via an immunohistochemical assay in HLA-eligible patients.

Purpose: RTOG 0617 was a phase III randomized trial for patients with unresectable stage IIIA/IIIB non-small cell lung cancer comparing standard-dose (60 Gy) versus high-dose (74 Gy) radiotherapy and chemotherapy, plus or minus cetuximab. Although the study was negative, based on prior evidence that patients with the KRAS-variant, an inherited germline mutation, benefit from cetuximab, we evaluated KRAS-variant patients in RTOG 0617.

Experimental Design: From RTOG 0617, 328 of 496 (66%) of patients were included in this analysis.

Article Synopsis
  • A study was done to see if adding immunotherapy to a common lung cancer treatment (SABR) would be better than using SABR alone in patients with early-stage lung cancer.
  • The trial involved 156 people, where half received just SABR and the other half received SABR with immunotherapy (called I-SABR).
  • After about 33 months, the results showed that those who got I-SABR had a much better chance of not having their cancer return compared to those who received just SABR.

Article Synopsis
  • Up to 20% of patients with non-small cell lung cancer (NSCLC) experience brain metastasis, and this study investigates the safety of combining stereotactic radiosurgery (SRS) with immune checkpoint inhibitors (nivolumab and ipilimumab) for these patients.
  • A total of 13 patients were enrolled, with 10 evaluable for dose-limiting toxicities (DLTs), and only one patient experienced a DLT, indicating the treatment is generally well-tolerated.
  • The estimated 4-month intracranial progression-free survival rate was 70.7%, suggesting that this combination therapy could be effective for treating brain metastasis in NSCLC patients.

Article Synopsis
  • A study analyzed 424 patients with KRASG12C-mutant non-small cell lung cancer (NSCLC) and identified key genomic alterations (in KEAP1, SMARCA4, and CDKN2A) that lead to worse outcomes with KRASG12C inhibitors (KRASG12Ci).
  • These alterations allowed researchers to classify patients into different prognostic groups, indicating nearly 50% of those who experienced early disease progression.
  • The research suggests potential pathways not only associated with poor response (like PI3K/AKT/MTOR) but also hints that certain DNA damage response issues might improve KRASG12Ci effectiveness, paving the way for personalized treatment strategies.

The availability of agents targeting the programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) immune checkpoint has transformed treatment of advanced and/or metastatic non-small cell lung cancer (NSCLC). However, a substantial proportion of patients treated with these agents do not respond or experience only a brief period of clinical benefit. Even among those whose disease responds, many subsequently experience disease progression.
