Download or read book Overcoming Resistance to EGFR Inhibitors in EGFR Mutant NSCLC written by Anthony Faber and published by Academic Press. This book was released on 2023-01-30 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overcoming Resistance to EGFR Inhibitors in EGFR Mutant NSCLC presents updated information on how EGFR mutant lung cancers evolve to evade EGFR inhibitors, clinical strategies that identify these mechanisms, and how to implement newer therapeutic strategies to combat resistance and improve patient survival. As resistance to EGFR inhibitors is often through re-activation of MEK/ERK and PI3K pathways, or through loss of cell death responses, there is much overlap with resistance to targeted therapies in other paradigms, such as BRAF inhibitors in BRAF mutant melanoma, and HER2 inhibitors in HER2 amplified breast cancer. This book is a valuable resource for cancer researchers, clinicians, graduate students and other members of the biomedical field who are interested in promising treatments for lung cancer. - Presents historical context on how NSCLC and SCLC has been treated, with an emphasis on NSCLC and how the concept of EGFR inhibitors has been implemented - Discusses critical resistant mechanisms seen in the clinic to 1st, 2nd and 3rd generation EGFR inhibitors - Encompasses the current state of affairs in clinical trials to address resistance
Download or read book EGFR Directed Therapy in Lung Cancer written by So Yeon Kim and published by Cambridge University Press. This book was released on 2023-01-26 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) is a clinically important driver alteration affecting approximately one-third of lung cancer patients. Treatments for EGFR-exon 19 deletion and exon 21 L858R NSCLC have evolved over the last decade from first-generation reversible tyrosine kinase inhibitors (TKI) to third-generation irreversible TKIs, of which osimertinib has been the widely accepted as first-line therapy. Despite survival improvement seen with osimertinib and its efficacy against acquired T790M mutation, resistance through on-target and off-target pathways eventually develop. This Element describes the structural biology and pathophysiology of EGFR-mutant NSCLC and discusses past, current, and future treatment options in the metastatic, neoadjuvant, and adjuvant settings. It describes the biology and recently approved treatment for EGFR-exon 20 insertion mutation and the treatment for the uncommon exon 18 (G719X), 20 (S768I), and 21 (L861Q) mutations. It also outlines the promising clinical applications of circulating tumor DNA (ctDNA).
Download or read book Fast Facts Non Small Cell Lung Cancer written by M. O'Brien and published by Karger Medical and Scientific Publishers. This book was released on 2022-03-16 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite an overall decrease in tobacco use, lung cancer (80–85% of which is non-small-cell lung cancer [NSCLC]) is still the leading cause of cancer death in both men and women worldwide. Annual low-dose CT screening of high-risk individuals has the potential to detect early-stage tumors, which can usually be successfully treated with a combination of surgery, radiotherapy, and chemotherapy and, in some cases, targeted therapy. However, most patients with NSCLC still present with advanced or metastatic disease. For these patients, initial therapy is guided by the tumor’s molecular characteristics and patient’s performance status. Targeted therapies have significantly improved clinical outcomes and, for some patients with no targetable genetic alterations, immunotherapy has demonstrated significant overall survival benefit. This insightful guide is designed to bring you up to speed with the latest developments and is important reading for all health professionals and medical trainees working in this fast-moving field. Table of Contents: • Prevention and screening • Diagnosis and staging • Surgery • Radiotherapy • Systemic therapy in non-metastatic NSCLC • Systemic therapy in advanced-stage/metastatic disease without a molecular driver • Personalized treatment in advanced NSCLC • Oligometastatic disease and brain metastases
Download or read book Fast Facts EGFR Exon 20 Insertion Mutations in NSCLC written by Julia Rotow and published by Karger Medical and Scientific Publishers. This book was released on 2022-06-30 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lung cancer is still a major cause of death globally, but the development of personalized, precision medicine has had a marked effect on treatment management and improved clinical outcomes, particularly for those with advanced stage non-small-cell lung cancer (NSCLC). EGFR mutations are the third most common mutation found in patients with advanced stage NSCLC. First-line treatment with a traditional epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) is indicated for most patients, but not for patients with EGFR exon 20 insertion mutations (ex20ins). Instead, recent approvals of an EGFR ex20ins-specific TKI (mobocertinib) and a bispecific antibody (amivantamab) targeting both EGFR and mesenchymalepithelial transition factor (MET) offer the potential for improved outcomes in this patient population. Furthermore, new approaches to treatment continue to be developed and trials for new agents with greater activity against ex20ins mutations are ongoing. Table of Contents: • EGFR and mutations • EGFR mutation testing • Treatment decisions • Therapies in development

Abstract: Oncogenic mutations in lung cancer further our knowledge about cancer initiation and progression, and may guide personalized treatment. The fact that targeted therapy is most effective in subsets of patients with defined molecular targets indicates the need for classification of clinically-related molecular tumor phenotypes based on the presence of oncogenic mutations, including EGFR mutations and EML4-ALK rearrangements. The identification of EGFR mutations, in up to half of lung adenocarcinomas in Asians, could predict clinical sensitivity to tyrosine kinase inhibitor (TKI). However, testing for mutations is not always possible due to tumor tissue availability. The therapeutic decision sometimes remains a clinical one especially for elderly lung cancer patients but no known mutation status. We studied the survival outcomes of targeted therapy versus conventional chemotherapy in elderly patients with lung cancer when we did not yet have routine EGFR mutation testing and demonstrated comparable survival outcomes in targeted therapy compared to chemotherapy, implying that survival with targeted therapy could be better if the treatment population could be selected with EGFR mutations. Though testing for EGFR mutation in tumor biopsy have later become routine practice and remains the accepted reference for therapeutic decision, the detection of EGFR mutations in plasma DNA with high diagnostic performance will be useful adjunct for diagnostic and therapeutic monitoring. Among patients with EGFR mutations in tumor biopsy, the concurrent detection of EGFR mutation in plasma DNA was found to confer a less favorable prognosis in terms of overall survival than those patients with EGFR mutations in tumor biopsy but the corresponding mutation was not detected in plasma. Other oncogenic mutations with therapeutic implications in lung tumors are yet to be fully explored, like ALK, KRAS, ROS1 or NTRK1 mutations. It is not exactly the tumor - but the mutations in the tumor that need to be explored with reference to clinical behavior. Even with EGFR mutation with well-established clinical implications, further exploration into its mechanistic functions will help in understanding of drug resistance. Lung cancer cell lines established from patients with known mutation profiles could be useful tools for studying the biology of known molecular targets as well as for therapeutic testing. Four new lung adenocarcinoma and one mesothelioma cell lines were established from patients with different clinical characteristics and oncogenic mutation profiles. These cell lines with defined mutation profiles will provide tools for exploration of lung cancer and mesothelioma biology with respect to molecular therapeutic targets. The Large Tumor Suppressor 2 (LATS2) gene was a differentially expressed gene between EGFR mutant and wildtype lung adenocarcinomas. The differential LATS2 expression levels were predictive of survival in patients with resected lung AD and may modulate tumor growth via different signaling pathways in EGFR mutant and wild-type tumors. The identification of oncogenic mutations has led to a new paradigm of targeted therapy in lung cancer. Further improvements in outcome of lung cancer management will stem from research into the biology of oncogenic mutations and their clinico-pathological correlations, which would fuel parallel development of clinically efficaci

Download or read book Targeted Therapies for Lung Cancer written by Ravi Salgia and published by Springer. This book was released on 2019-06-26 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contextualizes translational research and provides an up to date progress report on therapies that are currently being targeted in lung cancer. It is now well established that there is tremendous heterogeneity among cancer cells both at the inter- and intra-tumoral level. Further, a growing body of work highlights the importance of targeted therapies and personalized medicine in treating cancer patients. In contrast to conventional therapies that are typically administered to the average patient regardless of the patient’s genotype, targeted therapies are tailored to patients with specific traits. Nonetheless, such genetic changes can be disease-specific and/or target specific; thus, the book addresses these issues manifested in the somatically acquired genetic changes of the targeted gene. Each chapter is written by a leading medical oncologist who specializes in thoracic oncology and is devoted to a particular target in a specific indication. Contributors provide an in-depth review of the literature covering the mechanisms underlying signaling, potential cross talk between the target and downstream signaling, and potential emergence of drug resistance.

Download or read book MET EGFR Dimerisation in Lung Adenocarcinoma is Dependent on EGFR Mutations and Altered by MET Kinase Inhibition written by Richard Lee and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prognosis in advanced stage lung cancer is extremely poor with few effective therapies. EGFR tyrosine kinase inhibitors (TKIs) have high response rates in patients with activating EGFR mutations and are now an established part of therapy in selected patients. Such advances herald a previously unprecedented enthusiasm for the possibilities of targeted therapy. Acquired resistance however is widespread - the EGFR T790M mutation in particular represents approximately 50% of these. MET amplification is also an important route of resistance and preclinical data suggests synergy between therapies targeting these two receptors. We hypothesized that EGFR mutation status determines the EGFR-MET interaction and response to MET inhibition. We tested this hypothesis by using cells derived from NCI-H1975, which possess L858R and T790M EGFR mutations. This cell model and a derived murine xenograft experiment provided a platform with which to test these ideas by using assays of tumorigenicity in vitro; tumour growth/stroma formation in vivo and a selective MET kinase inhibitor, SGX523. EGFR-MET interaction was assessed by a Förster Resonance Energy Transfer (FRET) Fluorescence Lifetime Imaging Microscopy (FLIM) assay developed as part of this thesis that quantified EGFR-MET dimer formation. SGX523 significantly reduced cell proliferation, xenograft tumour growth and ERK phosphorylation in the presence of the EGFR L858R-T790M mutations but not with EGFR L858R alone where SGX523 reduced stroma formation but not growth. SGX523 reduced EGFR-MET dimerisation in the EGFR L858R-T790M mutant but increased EGFR-MET interaction in the presence of EGFR L858R alone. Little effect was seen with EGFR WT in response to SGX523 for any of these indices. This thesis provides novel data for the mechanistic understanding of EGFR-MET heterodimerisation and the accompanying discussion explores how this is relevant for EGFR and MET targeted therapies.
