Abstract
ABSTRACT Because of diversities and disparities, lung cancer incidence and mortality rates among minorities are disproportionate compared with non-Hispanic White (NHW) populations. This review focuses on the disparities in lung cancer screening, diagnosis, treatment, and outcomes that minorities, mainly Hispanic and Black, experience compared with NHW populations. Despite efforts such as improving the eligibility criteria for screening to improve lung cancer survival rates, disparities persist, particularly among minority populations. However, the "Hispanic Paradox" describes the lower incidence and better survival rates observed in Hispanics compared with other ethnic groups best explained by possible contributions such as genetics and other factors such as dietary habits. Disparities in screening, particularly among underrepresented populations, are frequently explained by cultural, socioeconomic, and health care access barriers. There are also disparities in receiving appropriate treatment, such as surgical treatment, with fewer Hispanics and Blacks undergoing surgery than NHW individuals, resulting in lower overall survival rates. In addition, the prevalence of biomarker testing varies by racial and ethnic groups, influencing personalized treatment plans and outcomes. Finally, because of genetic and social determinants of health, the clinical outcomes of targeted therapy and immunotherapy may differ among minority populations. Identifying and addressing social determinants of health in real time are a "must" to have a significant impact in reducing lung cancer disparities. A comprehensive and multifaceted strategy is required to rectify disparities in cancer treatment. This strategy includes increasing levels of awareness and education, reducing financial and access barriers, and promoting increased diversity in clinical trial recruitment. By effectively addressing these complex challenges, the objective of providing equitable cancer care to all patients, regardless of race or ethnicity, can be achieved. To identify and address disparities, heightened awareness and education are essential. Access to health care is ensured by reducing financial and access barriers. Finally, increased diversity in clinical trial recruitment advances the generalizability of findings and promotes equitable representation of all racial and ethnic groups, resulting in improved outcomes for all patients.

Real-world Biomarker Testing Patterns in Patients with Metastatic Non-Squamous Non-Small Cell Lung Cancer (NSCLC) in a US Community-based Oncology Practice Setting. Clin Lung Cancer 2023:S1525-7304(23)00050-5. [PMID: 37080814 DOI: 10.1016/j.cllc.2023.03.002] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 02/28/2023] [Accepted: 03/02/2023] [Indexed: 03/22/2023]
Abstract
INTRODUCTION/BACKGROUND This study was designed to describe real-world changes in biomarker testing among patients with non-squamous, metastatic non-small cell lung cancer (mNSCLC) in a community oncology setting from 2015 to 2020. PATIENTS AND METHODS This retrospective study randomly selected 500 adult patients diagnosed with nonsquamous mNSCLC to undergo chart review and data extraction. Data were extracted and validated by 2 independent abstractors. Biomarker testing rates were described before and after national guideline updates and FDA approval of targeted agents. RESULTS At least 1 biomarker test was received by 89.4% of patients with mNSCLC. Of all patients, 46.6%, 34.6%, and 8.2% received both single-gene and next generation sequencing (NGS)-based testing, single-gene testing only, and NGS-based testing only, respectively. However, there were changes in testing rates at the time of drug approvals for targeted agents. Biomarker testing increased for ALK (45.0% before to 78.3% after ALK-targeted drug approval), BRAF (from 20.0% to 67.8%), EGFR (from 20.0% to 78.2%), NTRK (from 34.6% to 55.7%), and ROS1 (increased from 29.6% before approval to 74.2% after). Biomarker testing increased after changes were made to national guidelines for BRAF (from 18.8% before to 68.1% after inclusion in guidelines), NTRK (from 37.2% to 56.5%), and ROS1 (increased from 40.8% to 74.5% after guideline updates). Targeted therapy was received by 62.4% of patients with a positive biomarker. CONCLUSION Increases in biomarker testing rates were observed relative to targeted agent approvals and national guideline updates. However, many patients with non-squamous mNSCLC did not receive full genotyping in accordance with national guidelines and represent an opportunity to identify reasons and solutions for barriers to care.

Real-world ALK Testing Trends in Patients With Advanced Non-Small-Cell Lung Cancer in the United States. Clin Lung Cancer 2023; 24:e39-e49. [PMID: 36376172 DOI: 10.1016/j.cllc.2022.09.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 09/15/2022] [Accepted: 09/29/2022] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Patients with non-small-cell lung cancer (NSCLC) whose tumors harbor anaplastic lymphoma kinase (ALK) rearrangements can be treated with ALK tyrosine kinase inhibitors. We assessed real-world ALK biomarker testing and treatment patterns of patients with NSCLC in the United States. PATIENTS AND METHODS Data were extracted from the Flatiron Health electronic health record-derived deidentified database for patients aged ≥18 years with stage IIIB or IV NSCLC and ≥2 clinic visits between January 2011 and December 2019. RESULTS Among 60,025 eligible patients, tumors from 36,691 (61.1%) patients were tested for ALK rearrangements, and 1042 (2.8%) tested positive (ALK+). From 2011 to 2019, ALK testing rates increased from 33.1% to 73.0%; testing via fluorescence in situ hybridization declined from 68.3% to 32.1% while next-generation sequencing increased from <1% to 52.2%. Although tissue samples were more commonly used than blood (85.1% vs. 13.5% of tests), blood sample testing increased from 0.1% in 2011 to 28.2% in 2019. Median (interquartile range) time from diagnosis of advanced NSCLC to first ALK+ test result was 23 (13-43) days, including laboratory processing time of 9 (6-14) days. For the 24.7% of patients with an ALK+ test result who began treatment before receiving the positive result, chemotherapy was initiated most often overall until 2018 when immuno-oncology agents became most common. CONCLUSION Although ALK testing in NSCLC increased over time, testing rates among eligible patients did not reach 100% during the study period. Treatment decisions for some patients with NSCLC may have been made without important, guideline-recommended biomarker data.

Abstract
The complexity of cancer care requires integrated and continuous support to deliver appropriate care. An expert network with complementary expertise and the capability of multidisciplinary care is an integral part of contemporary oncology care. Appropriate infrastructure is necessary to empower this network to deliver personalized precision care to their patients. Providing decision support as cancer care becomes exponentially more complex with new diagnostic and therapeutic choices remains challenging. City of Hope has developed a Pyramidal Decision Support Framework to address these challenges, which were exacerbated by the COVID pandemic, health plan restrictions, and growing geographic site diversity. Optimizing efficient and targeted decision support backed by multidisciplinary cancer expertise can improve individual patient treatment plans to achieve improved care and survival wherever patients are treated.

European and US Real-World Treatment Patterns in Patients with Epidermal Growth Factor Receptor Mutation-Positive Non-Small Cell Lung Cancer: A Retrospective Medical Record Review. Drugs Real World Outcomes 2021; 8:537-545. [PMID: 34533784 PMCID: PMC8605952 DOI: 10.1007/s40801-021-00261-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/14/2021] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are the preferred first-line (1L) therapy for EGFR mutation-positive (EGFRm) advanced/metastatic non-small cell lung cancer (NSCLC). OBJECTIVE Our objective was to describe real-world treatment patterns and T790M testing practices in patients with 1L disease progression (Europe/USA) following treatment with first- or second-generation EGFR-TKIs. METHODS This was a retrospective, non-interventional medical record review of patients with EGFRm locally advanced/metastatic NSCLC from routine clinical practice (EGFR-TKI initiation: 1 January 2015 to 31 December 2017; follow-up: last available medical record). Endpoints were demographic/clinical characteristics, incidence of central nervous system (CNS) metastases/leptomeningeal disease, second-line (2L) treatment, T790M mutation testing, and osimertinib treatment prevalence. RESULTS Among 469 patients, 73% (n = 341/469) progressed on 1L EGFR-TKI treatment. Of those who progressed, 74% (n = 252/341) were tested for T790M, with 50% (n = 126/252) testing positive; 75% (n = 94/126) of T790M-positive patients received osimertinib (mostly 2L). Of the patients with progression, 24% (n = 83/341) did not receive 2L treatment, and 88% (n = 73/83) of these patients died. At diagnosis of advanced disease, 9% of patients (n = 41) had CNS metastases; at EGFR-TKI initiation, 14% of patients (n = 68) had CNS metastases. Over the study period, 11% of patients (n = 42) developed CNS metastases not detected at NSCLC diagnosis. CONCLUSIONS Rates of resistance mutation testing and subsequent utilization of recommended 2L therapies could be improved. As more targeted therapies are developed, it will be crucial to improve the molecular testing rates to ensure patients receive appropriate, effective, and timely treatment.

Abstract
INTRODUCTION Although guidelines recommend testing for actionable biomarkers for patients with advanced or metastatic non-small cell lung cancer (NSCLC), testing rates have varied. This study aimed to assess molecular testing patterns in a large network of US community-based oncology practices. METHODS This retrospective observational study examined adult patients with newly diagnosed stage IV NSCLC with ≥ 2 visits in The US Oncology Network from July 1, 2016 to September 30, 2019. Testing patterns were examined using electronic health record structured fields and chart review. Structured data were analyzed for the overall study population (cohort A), and structured and unstructured data were analyzed for a select cohort of 300 patients (cohort B). RESULTS In cohort A (n = 3337), programmed death ligand 1 (37%) was the most frequently tested biomarker documented in structured data, followed by epidermal growth factor receptor (36%), anaplastic lymphoma kinase (35%), ROS1 (20%), and BRAF (16%). According to unstructured data in cohort B (n = 300), epidermal growth factor receptor (80%) was the most frequently tested biomarker, followed by anaplastic lymphoma kinase (79%), programmed death ligand 1 (72%), ROS1 (71%), and BRAF (56%). The proportion of tests ordered prior to first-line (1L) treatment increased from 2016 to 2018 for all biomarkers, as did the proportion of test results available prior to 1L treatment. However, some of the test results became available after 1L or later lines of treatment were in progress. CONCLUSION Our study found increased testing rates over time and decreases in testing turnaround times. However, rates of testing for all biomarkers still need to improve, as does completion of testing prior to initiation of therapy.

Abstract
BACKGROUND Epidermal growth factor receptor (EGFR) mutation testing is recommended for selecting patients with non-squamous non-small cell lung cancer (NSCLC) for EGFR tyrosine kinase inhibitor drug treatment. OBJECTIVE The objective of this article was to systematically review available evidence on the utilisation and determinants of EGFR mutation testing of patients with NSCLC in routine clinical practice. PATIENTS AND METHODS Searches were made of five electronic databases (Web of Science, MEDLINE [Ovid], Science Direct, EMBASE and Scopus), bibliographies of relevant articles, studies that cited included studies and relevant cancer websites. Studies were included if they: (1) reported the rate of uptake of EGFR testing in patients with NSCLC; (2) were conducted in routine clinical practice settings; (3) were published in English prior to July 2017; and (4) had full text available. Studies were appraised using the STROBE and the National Institutes of Health (National Heart, Lung and Blood Institute) checklists. RESULTS Eighteen eligible studies were identified for this systematic review, published between 2011 and 2017, from the USA (n = 7), Canada (n = 2), Republic of Korea (n = 2), Norway (n = 1), Sweden (n = 1), Germany (n = 1), Spain (n = 1), New Zealand (n = 1), China (n = 1) and multiple countries from the Asia-Pacific region (n = 1). Overall, testing for EGFR mutations was undertaken in 16,146 of 52,257 study patients (31%), although testing rates varied widely between different studies (from 7.8% to 78.3%). Single institution retrospective audits reported higher rates of testing (median 65.7%, range 31.3-78.3%) than population-based retrospective cohort analyses (median 23%, range 11-69%) and multi-institutional cross-sectional practitioner surveys (median 19.8%, range 7.8-31.8%). Nine studies reported increasing rates of testing over the study period but maximum testing rates remained less than 75% in most studies. Factors associated with higher testing uptake rates included: female sex; younger age; former/no smoking; advanced stage of lung cancer; adenocarcinoma histology; better mobility; radiation therapy; available tissue specimen; and private insurance. Among 16,146 tested patients, EGFR mutations were detected in 4328 patients (26.8%). However, estimates of mutation prevalence were biased by incomplete and selective testing in many studies. CONCLUSIONS The uptake of EGFR mutation testing of patients with NSCLC is suboptimal in many parts of the world. Incomplete uptake of testing is fuelled by selective testing referral practices, sample limitations, and funding constraints.

Abstract
Non-small cell lung cancer (NSCLC) is a heterogeneous disease, and therapeutic management has advanced with the identification of various key oncogenic mutations that promote lung cancer tumorigenesis. Subsequent studies have developed targeted therapies against these oncogenes in the hope of personalizing therapy based on the molecular genomics of the tumor. This review presents approved treatments against actionable mutations in NSCLC as well as promising targets and therapies. We also discuss the current status of molecular testing practices in community oncology sites that would help to direct oncologists in lung cancer decision-making. We propose a collaborative framework between community practice and academic sites that can help improve the utilization of personalized strategies in the community, through incorporation of increased testing rates, virtual molecular tumor boards, vendor-based oncology clinical pathways, and an academic-type singular electronic health record system.
