Background: Non-Small Cell Lung Cancer (NSCLC) is the leading cause of cancer death worldwide. Although immune checkpoint inhibitors (ICIs) have shown remarkable clinical efficacy, they can also induce a paradoxical cancer acceleration, known as hyperprogressive disease (HPD), whose causative mechanisms are still unclear.
Methods: This study investigated the mechanisms of ICI resistance in an HPD-NSCLC model.
STK11 mutations correlate with poor prognosis for advanced NSCLC treated with first-line immunotherapy or chemo-immunotherapy according to KRAS, TP53, KEAP1, and SMARCA4 status.

Background: The upfront treatment of non-oncogene-addicted NSCLC relies on immunotherapy alone (ICI) or in combination with chemotherapy (CT-ICI). Genomic aberrations such as KRAS, TP53, KEAP1, SMARCA4, or STK11 may impact survival outcomes.
Methods: We performed an observational study of 145 patients treated with first-line IO or CT-ICI for advanced non-squamous (nsq) NSCLC at our institution tested with an extensive lab-developed NGS panel.
Background: As for squamous (Sq)-NSCLC, Checkmate-017 trial showed a significant overall survival (OS) improvement in favor of Nivolumab (Nivo) over Docetaxel in 2nd-line. We hypothesized that anticipating Nivo use, as early switch maintenance after 1st-line chemotherapy (CHT), might have improved survival as compared to delayed 2nd-line treatment.
Methods: EDEN was an open-label, 2-arm, phase III study which randomized (1:1) stage IIIB/IV Sq-NSCLC pts non-progressive after 1st-line platinum-based CHT, to receive early Nivo as switch maintenance (Arm A) or standard best supportive care followed by 2nd-line Nivo at disease progression (Arm B).
Article Synopsis
- Approximately 10% of lung adenocarcinomas (LUAD) have mucinous histology (LUADMuc), which is linked to a lighter/absent smoking history and a higher prevalence of KRAS mutations compared to LUAD without this histology (LUADnon-muc).
- A study analyzed features and treatment outcomes of LUADMuc and LUADnon-muc patients, revealing LUADMuc patients had less aggressive disease characteristics and a poorer response to current therapies, especially immunotherapy.
- Overall, LUADMuc showed lower objective response rates, shorter progression-free and overall survival compared to LUADnon-muc, highlighting a need for more effective treatment strategies for this subgroup.
Article Synopsis
- * In a study at an institution, two patients with class 3-mutated NSCLC showed significant responses to the EGFR tyrosine kinase inhibitor erlotinib after previous treatments failed; one achieved complete response and the other had a partial response.
- * Research indicated that class 3-mutated NSCLC cell lines demonstrated sensitivity to EGFR-TKIs at lower concentrations compared to class 1 and 2 mutations, suggesting that class 3 mutations could represent a new targetable group for treatment.
