STK11 mutations predict poor prognosis for advanced NSCLC treated with first-line immunotherapy or chemo-immunotherapy according to KRAS, TP53, KEAP1, and SMARCA4 status (ESMO 2023)

Conclusions STK11 aberrations hampered the mOS of nsq NSCLC pts treated with first-line IO or CT-IO. The negative prognostic impact seems to be unrelated to IO administration.

A Critical Review of the Prognostic and Predictive Implications of KRAS and STK11 Mutations and Co-Mutations in Metastatic Non-Small Lung Cancer. (PubMed, J Pers Med)

However, KRAS/STK11 co-mutations may predict primary resistance to ICI. Prospective KRAS/STK11-biomarker-driven randomized trials are needed to assess the predictive effect of various treatments on the outcomes for patients with metastatic NSCLC, as the majority of the published KRAS analyses are retrospective and hypothesis-generating in nature.

High tumor mutational burden and UV signature, as well as the presence of NF1 and PIK3CA mutations, are supportive of MCPyV-negative MCC, whereas KEAP1, STK11, and KRAS mutations are supportive of NEC in the appropriate clinical context. Although rare, the presence of a gene fusion is supportive of NEC.

If we find a germline locus or loci that could impact the development of lung cancers with EGFR and/or KRAS mutation, this might help in improving lung cancer prevention and screening for populations of Latin American origin and others. Furthermore, multiple studies now highlight the importance of EGFR mutation screening and EGFR-directed targeted therapy for lung cancer patients in Latin America and with origins in Latin America.

Neoadjuvant nivolumab plus ipilimumab in resectable non-small cell lung cancer. (PubMed, J Immunother Cancer)

Though treatment was feasible, due to toxicity the study arm was terminated early by investigator consensus. In light of this, and while the long-term disease-free status of patients who achieved pCR is encouraging, further investigation of neoadjuvant nivolumab plus ipilimumab in patients with resectable NSCLC requires the identification of predictive biomarkers that enrich for response.

Specific TP53 subtype as biomarker for immune checkpoint inhibitors in lung adenocarcinoma. (PubMed, EBioMedicine)

Our study demonstrated that not all TP53 mutations are equal in predicting efficacy in patients with LUAD treated with ICIs. Multi-center data showed that TP53 missense and nonsense mutations were significantly different in terms of associations with PD-L1 expression, IFN-γ signatures and TME composition. Special attention should be paid to potential TP53 mutation heterogeneity when evaluating TP53 status as biomarker for ICIs.

Molecular profiles in NSCLC and LC are substantially different and this may have direct consequences in the therapy decision process. For example, preferential loss of the CDKN2A locus in NSCLC could impact the response to immunotherapy drugs. In contrast, as MDM2 is a negative regulator of TP53 , MDM2 amplification in NSCLC could indicate therapeutic efficacy of MDM2 inhibitors in p53 mutant tumours.

Receptor Tyrosine Kinase Signaling Networks Define Sensitivity to ERBB Inhibition and Stratify Kras Mutant Lung Cancers. (PubMed, Mol Cancer Ther)

Interestingly, in human NSCLCs, phosphorylation of EGFR or ERBB3 was frequently detected in ASCs and squamous cell carcinomas. We conclude that analysis of in situ ERBB signaling networks in conjunction with ex vivo drug response profiling and biochemical dissection of adaptive RTK activities may serve as valid diagnostic approach to identify tumors sensitive to ERBB network inhibition.

[VIRTUAL] Association of molecular heterogeneity and actionable mutations with survival in lung cancer (AACR-II 2020)

Our results showed an increased median overall survival in patients with lung adenocarcinoma that harbor actionable mutations compared to wild-type patients. Exploiting the appropriate use of clinical and genomic data collected and maintained in patient registries may better account for patient populations seen in the academic and community settings to improve cohort selection for clinical trials and survival outcomes.

[VIRTUAL] CDKN2A mutation predicts immunotherapy resistance in stage III/IV NSCLC (AACR-II 2020)

In a large cohort of stage III/IV NSCLC patients treated with systemic therapy and RT, NGS identified CDKN2A mutation/deletion as a predictor of ICB resistance and poor outcome. In the context of recent evidence for sensitivity to CDK4/6 inhibition of CDKN2A-deficient tumors, our findings raise the possibility of utilizing currently available targeted agents in the treatment of CDKN2A-deficient NSCLC patients progressing on ICB.

[VIRTUAL] Mutational landscape of STK11, PD-L1 expression, and TMB in patients with non-small cell lung cancer (AACR-II 2020)

The results showed that in our cohort, Chinese NSCLC patients with STK11 GAs were enriched in PD-L1-neg/TMB-H subgroup and associated with a poor response to ICIs in Chinese NSCLC patients. We also found that co-mutations of STK11 and KEAP1 may have implications as a negative biomarker for guiding ICI treatment.

[VIRTUAL] Genomic alterations profiling by liquid biopsy and their association to immune checkpoints inhibitors (ICI) response in a cohort of non-small cell lung cancer (NSCLC) patients. (ASCO 2020)

"Our results support the idea that tumor alterations identified by liquid biopsy panels can potentially contribute as biomarkers of response to ICI in NSCLC. When analyzing the mutational panorama after ICI treatment, we find that those patients exhibiting KRAS and/or STK11 mutations in their ctDNA have a shorter PFS. Research Funding: None"

[VIRTUAL] Clinical characteristics and anti-PD-(L)1 treatment outcomes of KRAS-G12C mutant lung cancer compared to other molecular subtypes of KRAS-mutant lung cancer. (ASCO 2020)

"KRAS G12C mutations are present in 12% of patients with NSCLC and represent a relevant subtype of NSCLC given KRAS G12C inhibitors now in clinical development. Baseline characteristics including co-mutation patterns are similar between patients with G12C and non-G12C, except for smoking history. The efficacy of KRAS G12C direct inhibitors will need to be compared to other available therapies for KRAS mutant NSCLC (chemotherapy and PD-(L)1 inhibitors) to identify most effective therapeutic strategy."

[VIRTUAL] Long-term responders to PD-1 blockade in patients with advanced non-small cell lung cancer (NSCLC). (ASCO 2020)

"Long-term response (LTR, ongoing response ≥ 24 months) to PD-1 blockade is an uncommon but profound clinical outcome in metastatic lung cancers. Younger age and high TMB correlate with LTR; the combination of high TMB/high PD-L1 enriches for LTR but not STR. Features predicting long term response may be distinct from those predicting initial response."
