Raez Le, Uba R, North A, et al. In particular, it remains unexplored how driver mutations could be associated with distinct TIBs signatures and their role in tumor microenvironment. Furthermore, the results of the specific genetic analysis were reported at the 2019 World Conference on Lung Cancer (WCLC). However, the pro-portion of patients who may benefit from immunotherapy is limited and the factors sensitive or resistant to immunotherapy are not completely clear. The findings were published in … Here, we examine the efficacy of PD-1 inhibitors in these subgroups. STK11/LKB1, KRAS mutations and immune-related adverse events as predictors of response to immunotherapy in lung cancer. Nevertheless, novel biomarkers need to be further investigated, and a systematic prognostic … 1 We present a case of a STK11 mutated lung adenocarcinoma presenting a good outcome with immunotherapy. However, LKB1 is a multitask protein that participates in a number of biological processes relevant in tumor biology, including proliferation, apoptosis, angiogenesis, metabolism and DNA damage (1). Boris Sepesi, M.D. Immunotherapy drugs given as single therapies or in combination with chemotherapy do not appear to work as well in lung cancer cells with mutations in the STK11 gene … This study provided evidence suggesting that advanced NSCLC characterized by a genomic alterations in both STK11 and KRAS may not respond well to immunotherapy. Skoulidis et al. RESULTS: Overall, 60 of 4446 tumours (1.35%) … The most commonly used immunotherapies for lung cancer block the interaction between PD-1 and PD-L1. The tumor microenvironment plays an important role in immunotherapy. KRAS is the most common oncogenic driver in lung adenocarcinoma (LUAC). MD Anderson researchers are working to change that. Mutations linked with sensitivity or resistance to immunotherapy in mNSCLC. STK11/LKB1 mutations are a main driver of drug resistance to PD-1 inhibitors in patients with KRAS-mutant lung adenocarcinoma, therefore could predict the poor prognosis of immunotherapy in these patients. Over the last decade, based on the extensive development of preclinical animal studies and clinical trials, the efficacy, and mechanisms of immunotherapy have been fully explored. Lung cancer is the leading cause of cancer-related mortality worldwide. Patients with advanced non-small cell lung cancer (NSCLC) benefit from treatment with immune checkpoint inhibitors (ICIs). 2018;8(7):822‐ 2.Papillon-Cavanagh S, Doshi P, Dobrin R, Szustakowski J, Walsh AM. Cancer Discov. The study was led by Steven A. Rosenberg, M.D., Ph.D., chief of the Surgery Branch at NCI’s Center for Cancer Research, and was conducted at the NIH Clinical Center. The objective of this study was to evaluate the predictive … Background: Addition of pembrolizumab (P) to platinum-doublet chemotherapy [carboplatin (or cisplatin) and pemetrexed (CP)] prolongs overall survival and is a standard of care (SOC) for the 1 st line treatment of metastatic EGFR/ALK wild-type (wt) non-squamous non-small cell lung cancer (mnsNSCLC). Helpful Markers for Immunotherapy Response May Lie With Mutations, irAEs. STK11mutation is present in 20% of bronchial adenocarcinoma and is associated with the KRAS mutation in 30% and KEAP1 in 25% of cases. Content on this site is for research purposes only and is not intended to be a substitute for medical advice. [By] contrast, ARID1A mutations were predictive of benefit with durvalumab and tremelimumab immunotherapy as first-line treatment of non-small-cell lung cancer.” Non-small cell lung cancer (NSCLC) is the most ... to immunotherapy resistance like STK11 and other predictive factors. Forecasts of the American Cancer Society predict 228,820 new lung cancer cases and 135,720 associated deaths in 2020 alone (Siegel et al. The STK11-KEAP1 mutations also influence outcomes and need to be factored into our analysis of TMB and other outcomes of lung cancer.”[1] New hope for advanced urothelial cancer For patients with urothelial cancer who progress after receiving platinum/checkpoint inhibitors, few … are the most prevalent oncogenic driver of non-small cell lung cancer (NSCLC), accounting for 20–30% of the lung adenocarcinoma cases.1 They are associated with cigarette smoking and have been linked to poor prognosis without available targeted Recent FDA approvals for immunotherapy drugs for treating lung cancer are exciting, but there still are many things we need to learn about this new field of cancer treatment. Non-small-cell lung cancer (NSCLC) is the most common histological type of lung cancer, accounting for 80–85% of lung cancers and has become the most fatal cancer in the world. Purpose: By unlocking antitumor immunity, antibodies targeting programmed cell death 1 (PD-1) exhibit impressive clinical results in non–small cell lung cancer, underlining the strong interactions between tumor and immune cells. This dissertation covers a variety of the genetic and molecular abnormalities of lung adenocarcinoma with an emphasis on STK11 loss and its implications on immunotherapy response. The role of tumor-infiltrating B-cells (TIBs) and intratumorally-produced antibodies in cancer-immunity interactions essentially remains terra incognita. Objective response rates to PD-1 blockade differed significantly among KL (7.4%), KP (35.7%), and K-only (28.6%) subgroups (P < … RESULTS: Overall, 60 of 4446 tumours (1.35%) … Here, we examine the efficacy of PD-1 inhibitors in these subgroups. Immunotherapy drugs that free the immune system to at… Results from the 2020 World Conference on Lung Cancer Singapore demonstrated the feasibility of using STK11 mutations and immune-related adverse events as response predictors in patients with non–small cell lung cancer. Lung cancer represents the first and second cause of cancer mortality and incidence worldwide respec - tively. Rizvi commented “We were able to show that either KEAP1 or STK11 mutations were associated with worse survival, irrespective of immunotherapy or chemotherapy treatment. However, factors that can robustly predict long-lasting responses are still needed. Presented at: IASLC 2020World Conference on Lung Cancer; January 28-31, 2021; Virtual. This targeted immunotherapy led to cancer regression in the patient in the study. IO+CT SOC in naïve pts with PD-L1<50% 3. Purpose: KRAS mutations occur in approximately 25% of patients with non–small cell lung cancer (NSCLC). Lung CA seen on CXR. Potential Treatments Targeting STK11 Mutations in Lung Cancer. Mutation status may provide insight as to which subgroups exhibit resistance to checkpoint inhibitor therapy. STK11/LKB1 mutations and PD-1 inhibitor resistance in KRAS-mutant lung adenocarcinoma. However, a 2018 study from the group of Dr. Ferdinandos Skoulidis, M.D., Ph.D. MD Anderson Cancer Center, showed that action of immunotherapy on cancer cells could be thwarted by the presence of STK11/LKB1 mutations in the genome bringing down … Biomarkers such as programmed death-ligand 1 (PD-L1), the tumor mutational burden (TMB) and the mismatch repair (MMR) status are used to predict the prognosis of ICIs therapy. Keywords: Immunotherapy; lung cancer; predictive biomarkers; circulating tumor DNA; STK11 220. Published in Cancer Discovery, the research paper shows that a gene called STK11 mutated or deleted in a third of non-small cell lung cancer patients, fosters an immunologically "cold” tumor microenvironment, with minimal penetration of tumors by … Co-occurring genomic alterations, particularly in tumour suppressor genes such as TP53 and LKB1 (also known as STK11), have emerged as core determinants of the molecular and clinical heterogeneity of oncogene-driven lung cancer subgroups through their effects on both tumour cell-intrinsic and non-cell-autonomous cancer hallmarks. Raez LE, Uba R, North A, et al. Coexisting alterations in KEAP1, PBRM1, SMARCA4 and STK11 define a subset of lung adenocarcinoma unresponsive to immunotherapy.. Tumors harboring co-mutations had inferior survival outcomes compared with both single-mutant and wild-type tumors. Methods: This study analysed 4446 patients for whom next-generation sequencing of tissue and/or circulating tumour DNA (ctDNA) had been performed. Bonanno L, De Paoli A, Zulato E, et al. a. Poster P33.14. Using biomarkers for personalizing immunotherapy in early stage lung cancer to determine which patients will likely benefit or experience toxicities from our new immunotherapy studies. The expression of PD-L1 decreased from 75.6% to 13.2% in one case, and decreased from 100% to 58.8% in one case. Immunotherapy drugs given as single therapies or in combination with chemotherapy do not appear to work as well in lung cancer cells with mutations in the STK11 gene versus those that do not have the mutation. Large cell neuroendocrine tumor (LCNEC) of the lung is a rare and aggressive tumor similar to small cell lung cancer (SCLC). The mutation of STK11, KEAP1 and ARID1A were analyzed in this study. ... We report a patient with lung cancer and 100% PD-L1 expression who developed hyperprogressive disease while treated with pembrolizumab and responded well to salvage chemotherapy with carboplatin and pemetrexed. Clinical activity with a second drug inhibiting KRASG12C confirms its role as a therapeutic target in patients with advanced non-small-cell lung cancer (NSCLC) harbouring this mutation, according to results from a study with the KRASG12C inhibitor adagrasib reported at the European Lung Cancer Virtual Congress 2021. e15135 Background: While the use of monoclonal antibodies targeting the PD-1 axis in metastatic non-small cell lung cancer (NSCLC) continues to expand since initial FDA approval in 2015, factors predictive of response still remain to be determined. We investigated the effects of coordinate STK11 and KEAP1 loss by comparing co-mutant with single mutant and wild-type isogenic counterparts in multiple LUAD models.STK11/KEAP1 co-mutation … Skoulidis et al [] identified three subgroups of KRAS-mutant LUAC: the KL subgroup, co … With more research, this could help inform treatment decisions for patients with these gene mutations. Presented at: 2021 World Conference on Lung Cancer Singapore, January 28-31, 2021. Abstract. Here we analyzed associations of immunoglobulin isotypes and clonality with … The presence of an STK11 mutation does not impact first-line treatment. However, researchers are looking closely at the role immunotherapy in patients with an STK11 mutation. Data show the presence of an STK11 mutation may make immunotherapy less effective. The finding appeared Dec. 8, 2016, in the New England Journal of Medicine. Studies have found STK11 mutation resistant to immune checkpoint inhibitors (ICIs) and worse survival in KEAP1 mutant patients compared with wildtype in response to ICIs [1, 2].It has demonstrated that less immune cell infiltration could be found in patients with non-small cell lung cancer (NSCLC) harbored STK11/KEAP1 mutation, which maybe lead to the resistance or worse survival to … Our results identify alterations as a major driver of primary resistance to PD-1 blockade in -mutant LUAC. Background: STK11 is an important tumour suppressor gene reported to confer immunotherapy resistance in non-small-cell lung cancers (NSCLC) especially in the presence of KRAS co-alterations. The recent novel conception of neoadjuvant immunotherapy has generated interest among surgeons worldwide, especially the lack of experience involving surgical treatment for the neoadjuvant immunotherapy population. In their report, 35 KRAS-mutant KRAS mutation + STK11 mutation | Non Small Cell Lung Cancer | PD-L1 inhibitor VERI is free for non-commercial use, no login needed. The most common type of lung cancer immunotherapy is called an immune checkpoint inhibitor. Advances in immuno-oncology are changing the standard of care for non–small cell lung cancer (NSCLC) through immunotherapies, including tumor vaccines, cellular immunotherapies, and immune checkpoint inhibitors (ICIs), that aim to establish or enhance effective immune responses toward a tumor. Lung cancer mortality has decreased over the past decade and can be partly attributed to advances in targeted therapy and immunotherapy. These include, but are not limited to, STK11, ... they eventually can be utilized in clinical practice for precision medicine in cancer immunotherapy. Oncogene 2011;30:3784-91. Patients registered at Step 0 must use the same SWOG patient ID for registration at Step 1. Thus, it is often treated similarly to SCLC in the front-line setting with a platinum doublet. Here, APCs include professional cel… There are four gene mutations (KRAS, TP53, STK11… Association of STK11/LKB1 genomic alterations with lack of benefit from the addition of pembrolizumab to platinum doublet chemotherapy in non-squamous non-small cell lung cancer. Frequent homozygous deletion of the LKB1/STK11 gene in non-small cell lung cancer. profound and long-lasting response to immune checkpoint inhibitors (ICIs) in a subset of non-small cell lung cancer (NSCLC) patients makes it Despite the uniform presence of KRAS mutations, patients with KRAS -mutant NSCLC can have a heterogeneous clinical course. LKB1 is a tumor suppressor helping the cells to not divide so fast and in an uncontrolled way. By: Scott Merville From: mdanderson.org Immunotherapy drugs have produced promising results in cancers like melanoma and leukemia, yet the drugs only work for 20 percent of lung cancer patients. Despite the recent implementation of immunotherapy as a single treatment or in combination with chemotherapy for first-line treatment of advanced non-small cell lung cancer (NSCLC), many patients do not benefit from this regimen due to primary treatment resistance or toxicity. There is some evidence from the CheckMate-057 trial that immunotherapy might represent a very valid treatment option for patients with KRAS-mutant lung cancer. PD-L1 is a protein that has a broader presence, including on the tumor cells. The relationship between gene alterations and response to anti-PD-L1 with and without anti-CTLA-4 are not well characterised. STK11/LKB1, KRAS mutations and immune-related adverse events as predictors of response to immunotherapy in lung cancer. Oncology/Hematology > Lung Cancer Next-Gen Sequencing Predicts NSCLC Tx Response — Targeted NGS accurately estimates tumor mutation burden. Interestingly, a multicenter retrospective analysis To participate in LUNGMAP, patients must be registered to Step 1 after evaluation of patient eligibility, including tumor tissue adequacy, per protocol Section 5.1, Step 1. KRAS is the most common oncogenic driver in lung adenocarcinoma (LUAC). He said there is evidence that a mutation in LKB1/STK11 may be beneficial in immunotherapy treatment. Ph II Randomized Study of Ramucirumab Plus MK3475 (Pembrolizumab) Versus Standard of Care for Patients Previously Treated with Immunotherapy for Stage IV or Recurrent Non-Small Cell Lung Cancer (Lung-MAP Non-Matched Sub-Study). Somatic mutations have been reported in up to 30% of Caucasian non-squamous non-small cell lung cancer (NSCLC) patients. small-cell lung cancer (aNSCLC).1–6 However, the response rate to ICI therapy remains relatively low (~20%); thus, the majority of aNSCLC patients could not benefit from this treatment. “There have been some molecular determinants such as STK-11 mutation and KEAP1 mutation that have emerged as potential biomarkers for resistance to immunotherapy with PD-1 or PD-L1 inhibitors,” Dr. Yan explained. Introduction. Given that lung cancer is the leading cancer killer, novel therapies are in great demand. Thus, it is often treated similarly to SCLC in the front-line setting with a platinum doublet. uncertain due to the distant relationship between lung cancer and Lynch syndrome (6). Chicago, IL—Response to immunotherapy in non–small-cell lung cancer (NSCLC) differs depending on the driver mutation involved and on the amount of PD-L1 expression within the tumor. In addition, STK11 gene is significantly co-mutated with KEAP1 gene. STK11/LKB1, KRAS mutations and immune-related adverse events as predictors of response to immunotherapy in lung cancer. Lung cancer is the leading cause of cancer-related deaths worldwide. If you have non-small cell lung cancer, it is important to talk to your doctor about comprehensive biomarker testing to see if you have an STK11 mutation or another biomarker. We expect the clinical development plan for this inhibitor in STK11-mutant lung cancer to be the first to combine the power of genetic patient selection and checkpoint inhibitor therapy. There are ~200,000 new lung cancer diagnoses each year is the US, 85% of which are non-small cell lung carcinomas (NSCLC). DCTD Convenes 2019 Lung Cancer Specialized Programs of Research Excellence (SPORE) Workshop. Primary Objectives. Challenges we face with testing tumor tissue in advanced NSCLC Extending effective immunotherapy to more patients. The Cancer Genome Atlas (TCGA) 18 included LUAD (n = 515) and LUSC (n = 501) cohorts, containing untreated samples from NSCLC (total n = 1016), for which gene expression data (in transcripts per million) are available. 1. Immunotherapy drugs that free the immune system to attack cancer have provided durable responses for about 20 percent of lung cancer patients, which has provided a pair of challenges to researchers:. Abstract. The STK11-KEAP1 mutations also influence outcomes and need to be factored into our analysis of TMB and other outcomes of lung cancer.”[1] New hope for advanced urothelial cancer For patients with urothelial cancer who progress after receiving platinum/checkpoint inhibitors, few treatment options exist. However, little is known about the association between the RAD54L gene and immunotherapy in lung cancer. Background: STK11 (also known as LKB1) and KEAP1 mutations have been associated with chemoresistance and poor outcomes and shown to be more frequent in PD-L1-negative tumors with high tumor mutational burden (TMB). Skoulidis F, Goldberg ME, Greenawalt DM, et al. Cancer.Net Associate Editor Jyoti Patel, MD, answers some of the questions that surround lung cancer and immunotherapy, during Lung Cancer Awareness Month. Biomarker-Integrated Approaches of Targeted Therapy for Lung Cancer Elimination. Kitajima and colleagues dissect the underlying mechanism of this immune-resistant phenotype, demonstrating that LKB1 loss leads directly to suppression of stimulator of interferon genes (STING) and insensitivity to cytoplasmic double-strand … Accessed January 31, 2021. STK11/LKB1 mutations are a main driver of drug resistance to PD-1 inhibitors in patients with KRAS-mutant lung adenocarcinoma, therefore could predict the poor prognosis of immunotherapy … However, treatment for patients beyond the first line remains undefined. In addition, STK11/LKB1 mutations also have implications on cysteine metabolism. STK11 mutations may assume oncogenic functions, associated to reduced survival in lung adenocarcinoma. In lung adenocarcinoma, KEAP1 loss often co-occurs with STK11 loss and KRAS-activating alterations.
