When damaged, as can occur in some lung cancer cells, EGFR doesn't perform the way it should. Patients with cancer that has an EGFR mutation generally respond positively to treatment with the drug erlotinib (Tarceva ). Background: Patients with thyroid transcription factor 1 (TTF1) negative lung adenocarcinoma (ADC) have been reported to have a worse prognosis and to lack epidermal growth factor receptor (EGFR) mutations. Peripheral blood was collected from each patient on a regular basis for . Tyrosine phosphoproteomics identifies both codrivers and cotargeting strategies for T790M-related EGFR-TKI resistance in non-small cell lung cancer. This book is a compilation of research development lead by expert researchers and it establishes a single reference module. Acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors in non-small-cell lung cancers dependent on the epidermal growth factor receptor pathway. Lung cancer is still the leading cause of cancer-related death worldwide. Why are you doing it and which chemotherapy do you use? SOCINSKI: Is that OK with you? November 17, 2021. However, they may not use it as a first line treatment when the results are negative. 1.Introduction. Regulatory insights on osimertinib by the FDA stated that the survival follow-up of patients taking the placebo was confounded by subsequent treatment after recurrence. Case presentation: A 61-year-old female (never smoker) who initially presented with headache and dizziness was diagnosed with lung adenocarcinoma with multiple brain metastasis (cT2aN3M1b stage IV), and was negative for EGFR and ALK. Methods: In all lung cancer patients diagnosed in the University Hospital of . Optimal sequencing strategies in the treatment of EGFR mutation-positive non-small cell lung cancer: Clinical benefits and cost-effectiveness. First, all three trials were designed as head-to-head comparisons between epidermal growth factor receptortyrosine kinase inhibitor (EGFR-TKI) and doublet chemotherapy, which is different from the ADAURA (Osimertinib Versus Placebo in Resected EGFR-Mutated NSCLC With or Without Adjuvant Chemotherapy) and ALCHEMIST (Erlotinib in Treating Patients With Stage IB-IIIA NSCLC Completely Removed by Surgery) trials. SOCINSKI: Yes, this addresses the multidisciplinary team, in terms of who orders [tests]. The miR6253p/AXL axis induces nonT790M acquired resistance to EGFRTKI via activation of the TGF/Smad pathway and EMT in EGFRmutant nonsmall cell lung cancer. The crossover to TKI therapy by 83% of patients in the adjuvant cis/vin arm after disease relapse affected the final OS results. b. EGFR MUTATION NEGATIVE. PEREZ: Even back in the day, before the late-stage NGS was approved, we were already doing it.So thats where were eventually going. The hazard ratio is about 0.86. In addition to rare incidence of anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 receptor kinase (ROS1) positive patients, patients with brain metastases of non-small cell lung cancer (NSCLC) without epidermal growth factor receptor (EGFR) sensitive mutation have no effective systemic therapy at present, and the overall prognosis is poor.Since the low blood-brain barrier permeability of . The book is unique in that it is written by experienced thoracic surgeons, pulmonary medicine physicians, and cytopathologists who use EBUS-TBNA in a large medical center. Zhou, C. et al. Although negative OS data were reported, the 5-year OS rate of 78.0% reported by the IMPACT, and 53.2% reported by the CTONG1104 trial were the best in this era when only adjuvant chemotherapy without EGFR-TKI was available in each country.10 Besides, the OS benefit was significantly affected by later lines of antitumor treatment. e20004. In general, activating EGFR mutations are more commonly observed in patients with adenocarcinomas and no prior history of smoking, as well as in females and those of Asian descent. EGFR (the gene that produces a protein called epidermal growth factor receptor) is abnormal, or mutated, in about 10 percent of patients with non-small cell lung cancer and in nearly 50 percent of lung cancers arising in those who have never smoked.. T790M mutations within exon 20 result in 60% of . Before a patient begins lung cancer treatment, an experienced lung cancer pathologist must review the pathologic material. TAPUR Study, Terms of Use | Privacy Policy | That question is an important question because we have a series of IO adjuvant trials and neoadjuvant trials coming at us in the near future. The drug may still inhibit cancer growth, but is less likely to cause dramatic tumor shrinkage. The discovery of activating mutations in the epidermal growth factor receptor (EGFR) gene and the development of EGFR tyrosine kinase inhibitors (TKIs) have led to a paradigm shift in the treatment of non-small cell lung cancer (NSCLC). If you do convince them, maybe you were not honest. EGFR-positive lung cancer refers to lung cancers that show evidence of an EGFR mutation. Meaning chemotherapy may be offered first in stead. but negative for CK5/6, p63 and CK20 -compatible with primary from lung Undoubtedly, EGFR-TKIs, with their . In the case of EGFR-positive non small cell lung cancer (NSCLC), a mutation, or damage, in the EGFR gene causes the EGFR protein to remain stuck in the "on" position. -, N Engl J Med. Reviewers This study aimed to evaluate the predominant progressive disease (PD) pattern limited to residual sites of . NAKKA: Yes, its all right. If youre removing a 5.5-cm tumor, youre not too worried about how much tissue you have, but that can be a concern when you just have a biopsy. 2015 Oct 22;373(17):1627-39 Download Slideset. During a Targeted Oncology Case-Based Roundtable event, Mark A. Socinski, MD, executive medical director, AdventHealth Cancer Institute and member, Thoracic . Well, we can assume everyone is trying to use cisplatin if they can, but they realize that may not be possible in every patient. The curves gradually became close to each other after the drug cessation, indicating that prolonging the drug exposure time might delay the recurrence time and even prolong OS. The ASCO Post, ASCO eLearning AZZI: In terms of payers, [in my experience], theres no coverage for early stage. This book provides a comprehensive and up-to-date account of the physical/technological, biological, and clinical aspects of SBRT. It will serve as a detailed resource for this rapidly developing treatment modality. Pennell says the pace of discovery and development . [] Immunohistochemistry and electron microscopy are invaluable techniques for diagnosis and subclassification . I use carboplatin/ pemetrexed or cisplatin/pemetrexed, depending on the patient performance status. doublet in epidermal growth factor receptor (EGFR)negative lung adenocarcinoma. Thoroughly updated for its Second Edition, this text provides comprehensive, interdisciplinary coverage of gastrointestinal cancer, including molecular biology, diagnosis, medical, surgical, and radiation therapy, and palliative care. of the 65% of members who have provided data, 73% have already. Du W, Sun L, Liu T, Zhu J, Zeng Y, Zhang Y, Wang X, Liu Z, Huang JA. There are some very early OS data. -, Sci Transl Med. Found inside Page 324with chemotherapy in phase II studies for patients with advanced-stage NSCLC [4244]. Of note, the positive study with cetuximab was unique in that it selected patients for therapy based on EGFR expression status. gefitinib, erlotinib . Its not 100%. The few general onco logy textbooks are generally out of date. Single papers in specialized journals are informative but seldom comprehensive; these are more often preliminary reports on a very limited number of patients. A recent meta-analysis revealed that anti-EGFR agents used in the treatment of solid malignancies increases the risk of VTE by 32%. DEMPSEY: For me, the decision between cisplatin vs paclitaxel comes down to the last few [factors]. We didnt have EGFR data of adjuvant chemotherapy when the study was done in the 1980s and 1990s. Although PD-L1 expression is not . 30 , 1311-1320 (2019). This is critical because SCLC, which responds well to chemotherapy and is generally not treated surgically, can be confused on microscopic examination with NSCLC. We have OS data on that, especially in the patients with stage III disease. Because youre having these same conversations with patients with breast cancer and patients with colon cancer, I assume, but is it the same conversation youre having with patients with lung cancer? Researchers report on a multinational, early phase clinical trial evaluating a new targeted therapy for patients with . What factors predispose to the development of VTE in these patients is not known and has not been explored. ing the driver genes have been applied in the treatment of lung cancer and have shown great effectiveness in in-creasing the survival of advanced NSCLC.3,4 Epidermal growth factor receptor (EGFR) alterations, including L858R and short insertions/deletions (indels) in exon 19, Similar to the CTONG1104, EVIDENCE, and IMPACT trials, the KM curves showed an interesting spindle type. During a Targeted Oncology Case-Based Roundtable event, Mark A. Socinski, MD, executive medical director, AdventHealth Cancer Institute and member, Thoracic . Since 2017, when the ADJUVANT-CTONG1104 (Gefitinib Versus Vinorelbine/Platinum as Adjuvant Treatment in Stage II-IIIA(N1-N2) NSCLC With EGFR Mutation) trial first reported the positive disease-free survival (DFS) for adjuvant treatment with gefitinib compared with chemotherapy in resected EGFR-mutant nonsmall-cell lung cancer (NSCLC),1 several trials such as the EVAN (Erlotinib in Post Radical Operation NSCLC Patients With EGFR Mutation), EVIDENCE (Icotinib as Adjuvant Therapy Compared With Standard Chemotherapy in Stage II-IIIA NSCLC With EGFR-mutation), and SELECT (Surgery for Early Lung Cancer With Post-operative Erlotinib) trials have presented similar DFS results with various first-generation tyrosine kinase inhibitors (TKIs).2-4 In the article accompanying this editorial, Tada et al5 reported the DFS and overall survival (OS) results from the similarly designed IMPACT trial conducted in Japan. Gina. Do you have those conversations with your patients? than 20,000 people are diagnosed with EGFR positive lung cancer each. Anyhow, we can use the single gene, but we know this is just a matter of time before more effective inhibitors will also show benefit for early-stage disease. AZZI: There should be lobbying to change the Medicare rules for lung cancer, at least, [because] we know [we will need testing for EGFR], maybe ALK, and other alterations in the future. eCollection 2015. The intratumoral heterogeneity of the EGFR mutation alone may not be sufficient to identify the advantaged group.11,12 Identifying clonal targetable comutations from baseline specimens and during cancer evolution might help clinicians select the resistant subclones that might benefit from chemotherapy. Beyond that, one of my concerns is that, in metastatic disease, we now have 9 or 10 actionable alterations. The IMPACT trial might not be able to impact the clinical practice in the adjuvant setting for EGFR-mutant NSCLC right now. 2020;383(18):1711-1723. doi:10.1056/NEJMoa2027071, Case-Based Roundtable Meeting Spotlight November 2, 2021. EGFR mutation in lung cancer KRAS in colonic cancer . -, N Engl J Med. SAWHNEY: Patients who got chemotherapy benefited more from the osimertinib [Tagrisso]. Mark A. Socinski, MD, executive medical director of the AdventHealth Cancer Institute, discusses the role of immunotherapy in PD-L1-negative lung cancer. For stage III, I would give chemotherapy followed by osimertinib if theyre EGFR mutation positive. The remaining major cohort (72% of patients), who were negative for EGFR and ALK, received conventional chemotherapy treatment rather . The following represents disclosure information provided by authors of this manuscript. In this Book, an attempt is made to offer an insight on the common molecular techniques that are in use and recent advances in molecular diagnostics. Undoubtedly, EGFR-TKIs, with their . Immunotherapy [IO], at least as monotherapy, doesnt work very well. EGFR, or epidermal growth factor receptor, is a protein present on the surface of both healthy cells and cancer cells. Furthermore, in the pursuit of curing operable EGFR-mutant NSCLC, the existing findings centered around the understanding that adjuvant EGFR-TKIs mainly suppress tumor growth during treatment other than eliminating the microscopic disease completely.14 Hence, dynamic minimal residual disease (MRD) detection through circulating tumor DNA capture might be a promising way to define beneficial populations, the best time to initiate the adjuvant TKI, and optimal duration.15,16 Serial postoperative MRD positivity could predict an unfavorable DFS, precede radiographic progression, and help clinicians tailor adjuvant treatment to treat patients with a high risk of recurrence and award MRD-negative patients a drug holiday.17-20 Herein integrating MRD detection into a prospective study design could improve the clinical utility of this approach, eg, the MERMAID trial (A Phase III Study of Adjuvant Durvalumab plus Chemotherapy in Resected NSCLC patients with MRD+ post-surgery).21. 2014 Aug 1;20(15):4059-4074. doi: 10.1158/1078-0432.CCR-13-1559. EGFR mutation lung cancer is mostly found in non-small cell lung cancer. NAKKA: In the adjuvant setting, I explain we are reducing the risk of recurrence, and I typically use carboplatin/ paclitaxel. At the same time, cancer treatment is becoming more targeted and research focused on cancer treatment for KRAS-positive lung cancer is underway. This drug is given as an infusion into a vein (IV). During a Targeted Oncology Case-Based Roundtable event, Mark A. Socinski, MD, led a discussion about treatment of patients with EGFR-mutant non-small cell lung cancer. After a median follow-up of 70 months, the median PFS was 35.9 months in the gefitinib group and 25.1 months in the cis/vin group. Relationships may not relate to the subject matter of this manuscript. The cancer initially seemed to be responding, but her recent scans eCollection 2020 Dec.
