[PMID: 36900294 PMCID: PMC10001166 DOI: 10.3390/cancers15051505] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 02/21/2023] [Accepted: 02/24/2023] [Indexed: 03/04/2023] Open
Abstract
Clinical studies have shown the efficacy of EGFR- and ALK-directed therapies in non-small cell lung cancer (NSCLC). Real-world data on, e.g., testing patterns, uptake, and duration of treatment are scarce. Reflex EGFR and ALK testing of non-squamous NSCLCs were implemented in Norwegian guidelines in 2010 and 2013, respectively. We present a complete national registry data on incidence, pathology procedures, and drug prescription in the period of 2013 to 2020. Test rates for both EGFR and ALK increased over time and were 85% and 89%, respectively, at the end of the study period, independent of age up to 85 years. The positivity rate for EGFR was higher among females and young patients, whereas no sex difference was observed for ALK. EGFR-treated patients were older than ALK-treated patients (71 vs. 63 years at start, p < 0.001). Male ALK-treated patients were significantly younger than females at the start of treatment (58 vs. 65 years, p = 0.019). The time from the first dispensation to the last dispensation of TKI (as a surrogate for progression-free survival) was shorter for EGFR- than for ALK-TKI, and survival for both EGFR- and ALK-positive patients was substantially longer than for non-mutated patients. We found a high adherence to molecular testing guidelines, good concordance of mutation positivity and treatment, and the real-world replication of findings in clinical trials, indicating that the relevant patients are provided substantially life-prolonging therapy.

Use of ALK-tyrosine kinase inhibitors (ALK TKI) in clinical practice, overall survival, and treatment duration - a Swedish nationwide retrospective study. Acta Oncol 2022; 61:1354-1361. [PMID: 36368902 DOI: 10.1080/0284186x.2022.2133972] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/13/2022]
Abstract
BACKGROUND The real-world treatment and outcomes of patients with anaplastic lymphoma kinase positive (ALK+) advanced non-small cell lung cancer treated with ALK Tyrosine Kinase Inhibitor (TKI) drugs in Sweden is not well described. MATERIAL AND METHODS A retrospective population-based cohort study was conducted using Swedish national registers. All patients with a filled prescription for an ALK TKI between January 2012 and October 2020 were included. The sequencing of ALK TKI and duration of treatment (DOT) were described, and overall survival (OS) was estimated using the Kaplan-Meier method. Patients were stratified based on treatment with frontline chemotherapy, presence of CNS metastases prior to the first ALK TKI, and generation of ALK TKI agent. RESULTS Among the total of 579 patients, 549 (95%) underwent a therapy sequence in line with current clinical practice with 204 (37%) patients receiving frontline chemotherapy. Single-line ALK TKI was given to 366 patients (crizotinib: 211; alectinib: 146; ceritinib: 9), whereas 128 patients received two different ALK TKI (frontline crizotinib: 100, alectinib: 24, ceritinib: 4); 40 patients received three lines and 15 patients four ALK TKI lines or more. With frontline chemotherapy, the mean (standard deviation) DOT was 1.07 (1.25) years for the entire TKI therapy sequence compared to 1.23 (1.28) years with frontline ALK TKI. The median (95% confidence interval) OS was 1.83 (1.48-2.13) years for the entire cohort, 1.44 (0.89-1.98) years for patients given frontline chemotherapy, and 2.02 (1.60-2.58) years for patients given frontline ALK TKI. CONCLUSION This study provides a unique overview of the patient population treated with ALK TKI in Sweden and reveals the treatment patterns applied in real clinical practice. More research is needed when longer follow-up data are available for later-generation ALK TKI, to fully understand ALK TKI sequencing and its effect on patient survival in a real-world setting.

Abstract
This retrospective observational study analyzed the clinical characteristics, treatment patterns and outcomes of 120 patients with advanced ALK-positive non-small-cell lung cancer (ALK+ NSCLC) according to data collected between November 2019 and October 2020 in 38 Spanish hospitals. Patients had progressed after 1–5 prior treatment lines (which included crizotinib in any prior line) and received subsequent therapy with alectinib in a local expanded access program. Median age was 58.7 years, 50% of patients were female, 64.1% had ECOG PS of 0–1, 85% presented stage IV, 95% had adenocarcinoma histology and 20.8% had brain metastases. After a median 9.6 months of alectinib treatment, objective response rate (ORR) was 54.5%, disease control rate (DCR) was 80%, median progression-free survival (PFS) was 9.4 months and median overall survival (OS) was 24.1 months. Patients with brain metastases achieved an intracranial DCR of 71.4%. Adverse events (AEs) were reported in 35.8% of patients (14.2% of AEs were grade ≥3). Over 40% of patients received some treatment after alectinib, most frequently lorlatinib (65.2%) and brigatinib (32.6%). This study provides information on real-world treatment patterns and confirms the tolerability and prolonged PFS and OS observed with alectinib in clinical trials, in unselected pretreated patients with advanced ALK+ NSCLC.

[PMID: 34590010 PMCID: PMC8474209 DOI: 10.1016/j.jtocrr.2021.100157] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 02/01/2021] [Accepted: 02/10/2021] [Indexed: 11/24/2022] Open
Abstract
Introduction This study explored the use, safety, and efficacy of initial use of an ALK-inhibiting targeted therapy (ALK tyrosine kinase inhibitor [TKI]) in patients with ALK-rearranged NSCLC in a population-based, real-world clinical population within the province of Alberta, Canada. Methods Demographic, clinical, treatment, and outcome data of the patients with advanced or metastatic ALK-rearranged NSCLC receiving their first ALK TKI between 2014 and 2019 were included in the analysis. Results A total of 92 patients with ALK-rearranged NSCLC treated with ALK TKI (78% crizotinib, 22% alectinib) were identified. In the ALK-rearranged cohort, 1-year survival rate was 73% and median overall survival (OS) and progression-free survival (PFS) were 48.5 months and 17.0 months, respectively. An objective response rate of 49% was observed, and adverse events were reported in 70% of the patients, primarily of low grade (84%). Case-matched comparison to patients with ALK-wildtype disease treated with cytotoxic chemotherapy revealed the benefit of ALK TKI in the context of an ALK rearrangement (ALK-rearranged versus ALK-wildtype) (median post-treatment initiation OS: 46.8 versus 14.2 mo, p < 0.001). Outcomes, measured from the time of ALK TKI initiation, differed by Eastern Cooperative Oncology Group (ECOG) (ECOG < 2 versus ECOG ≥ 2) (median OS: not reached versus 6.8 mo, p < 0.001; median PFS 17.6 versus 7.4 mo, p = 0.02), disease presentation (relapsed versus de novo) (median PFS: 30.8 versus 15.0 mo, p = 0.04), and brain metastasis onset (brain metastases development during ALK TKI versus baseline brain metastases) (not reached versus 12.8 mo, p = 0.04). Conclusions Clinical trials have firmly established that ALK TKIs are safe, well tolerated, and effective; these findings reveal that their impact in a real-world setting is just as profound. The availability and use of ALK TKI therapies contribute to the impressive gains in survival experienced by contemporary patients with ALK-rearranged disease, rendering patients with this oncodriven form of NSCLC among the longest surviving patients with lung cancer.

Real-World Utilization of Target- and Immunotherapies for Lung Cancer: A Scoping Review of Studies Based on Routinely Collected Electronic Healthcare Data. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18147679. [PMID: 34300130 PMCID: PMC8305284 DOI: 10.3390/ijerph18147679] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 07/14/2021] [Accepted: 07/15/2021] [Indexed: 01/01/2023]
Abstract
Routinely collected electronic healthcare data (rcEHD) have a tremendous potential for enriching pre-marketing evidence on target- and immunotherapies used to treat lung cancer (LC). A scoping review was performed to provide a structured overview of available rcEHD-based studies on this topic and to support the execution of future research by facilitating access to pertinent literature both for study design and benchmarking. Eligible studies published between 2016 and 2020 in PubMed and ISI Web of Science were searched. Data source and study characteristics, as well as evidence on drug utilization and survival were extracted. Thirty-two studies were included. Twenty-six studies used North American data, while three used European data only. Thirteen studies linked ≥1 data source types among administrative/claims data, cancer registries and medical/health records. Twenty-nine studies retrieved cancer-related information from medical records/cancer registries and 31 studies retrieved information on drug utilization or survival from medical records or administrative/claim data. Most part of studies concerned non-small-cell-LC patients (29 out of 32) while none focused on small-cell-LC. Study cohorts ranged between 85 to 81,983 patients. Only two studies described first-line utilization of immunotherapies. Results from this review will serve as a starting point for the execution of future rcEHD-based studies on innovative LC pharmacotherapies.

Abstract
BACKGROUND National Comprehensive Cancer Network (NCCN) guidelines recommend biomarker testing as the first step in the management of patients with advanced non-small cell lung cancer (aNSCLC). We assessed anaplastic lymphoma kinase (ALK) testing rates and factors related to underuse in community medical systems between 2012 and 2019 to understand guideline adoption. METHODS A retrospective observational study using a nationwide electronic health record (EHR)-derived deidentified database was conducted. Patients with aNSCLC diagnosed in community medical centers from January 2012 to May 2019 were included to describe the ALK testing trend. This cohort was further restricted to patients diagnosed after 2015 to understand factors associated with testing underuse using mixed-effects multivariable logistic regression models. RESULTS Trends for increased ALK testing rates by year were observed in both NCCN guideline-eligible patients (59.5% in 2012 to 84.1% in 2019) and -ineligible patients (15.6% to 50.8%) in a cohort of 41,728 patients. Histology type and smoking status had the greatest impact on test use. Compared with patients with nonsquamous histology and no smoking history, patients with squamous histology and no smoking history (adjusted odds ratio [aOR], 7.6; 95% confidence interval [CI], 5.6-10.4), NSCLC histology not otherwise specified (NOS) with smoking history (aOR, 3.4; 95% CI, 2.8-4.2); NSCLC NOS/nonsmoker (aOR, 1.8; 95% CI, 1.1-3.2), and nonsquamous/smoker (aOR, 1.5; 95% CI, 1.3-1.7) were less likely to be tested. Factors related to underuse also included Eastern Cooperative Oncology Group performance status, stage at initial diagnosis, and demographics. CONCLUSION This analysis of real-world data shows increasing test use by year; however, one fifth of patients eligible for ALK testing still remain untested and potentially missing therapeutic options. IMPLICATIONS FOR PRACTICE Advancement in treatment of lung cancer is accompanied by an increasing number of tests that should be run to determine potential therapy options for each patient. This study assessed adoption of testing recommendations for anaplastic lymphoma kinase rearrangements in a national database. Although test use increased over the time period studied (2012-2019), there is still room for improvement. Efforts are needed to increase test use in undertested groups, thus enabling eligible patients to benefit from novel lung cancer therapies.

Abstract
Aims: Premarketing clinical trials are typically conducted under controlled conditions and in selected study populations, so real-world information on the utilization of new cancer drugs is limited. We aimed to explore the potential of German claims data in this regard, exemplified by the ALK inhibitor crizotinib, used in non-small-cell lung cancer therapy. Materials & methods: We identified patients treated with crizotinib in the German Pharmacoepidemiological Research Database (2004-2017; 20% of the German population) and assessed patient characteristics, treatment and survival. Results: We identified 348 crizotinib-treated patients (56% female; 25% first-line users). After 2 years, overall survival was 48%, with higher survival in men than in women (58 vs 40%). Overall, 76% of patients discontinued crizotinib treatment. Of those, 41% received another ALK inhibitor afterward. Conclusion: The results underline the potential of German claims data for real-world monitoring of oncological drug utilization.

Abstract
BACKGROUND Little is known about real-world treatment and outcomes of patients with anaplastic lymphoma kinase-positive (ALK+) advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS This retrospective study of the Flatiron Health EHR-derived deidentified database included patients with a lung cancer diagnosis and confirmed advanced NSCLC who received ALK tyrosine kinase inhibitor (TKI) therapy (January 1, 2011, through June 30, 2018). Patient characteristics and treatment patterns were characterized. Real-world progression-free survival (rwPFS) and time to discontinuation were calculated using the Kaplan-Meier method. RESULTS First-line ALK TKI therapy was administered to 581 patients (27.5% had brain metastasis on or prior to initiation) and second-line ALK TKI therapy to 254 patients post crizotinib (45.7% had brain metastasis on or prior to second-line ALK TKI initiation). Crizotinib (84.6%; n = 492) was the most commonly administered first-line ALK TKI therapy. For second-line ALK TKI post crizotinib (n = 254), 49.6% received ceritinib, 41.7% received alectinib, 5.9% received crizotinib retreatment, and 2.8% received brigatinib. Median (95% confidence interval [CI]) rwPFS was 7.47 (6.48-8.32) months for first-line and 7.30 (5.72-8.42) months for second-line ALK TKI. Median (95% CI) rwPFS was significantly longer among first-line ALK TKI patients without than with brain metastasis (8.52 [7.57-10.59] vs. 4.97 [3.75-5.99] months; p < .0001) and patients with brain metastasis on or prior to first-line ALK TKI therapy had a significantly increased risk of progression (hazard ratio ± SE, 1.976 ± 0.112; p < .0001). CONCLUSION Median rwPFS in patients with advanced ALK+ NSCLC was < 8 months for first- and second-line ALK TKI therapy and was even shorter in patients with brain metastasis, highlighting the need for more effective treatments in this patient population. IMPLICATIONS FOR PRACTICE Results presented herein describe real-world treatment of advanced ALK+ NSCLC with ALK TKI therapies from January 2011 through June 2018. Crizotinib was the most commonly prescribed first-line ALK TKI therapy in this patient population, but the majority of data analyzed were obtained prior to Food and Drug Administration approval of alectinib and ceritinib in the first-line ALK TKI setting. Physicians should monitor patients closely to help identify when a change in treatment should occur.

Abstract
BACKGROUND Targeted therapy for patients with non-small-cell lung cancer (NSCLC) harboring ROS proto-oncogene 1 (ROS1) rearrangements was approved in 2016. However, little is known about real-world ROS1 testing practices in United States community practice. We aimed to characterize ROS1 testing rates and identify potential barriers to ROS1 testing. PATIENTS AND METHODS Flatiron Health's de-identified electronic health record-derived database was used to identify patients diagnosed with advanced NSCLC from July 2016 through December 2018 who received systemic treatment in a community practice setting. ROS1 and other biomarker testing was recorded. Regression analysis identified demographic and clinical characteristics associated with occurrence of ROS1 testing, longer time (≥ 25 days) from diagnosis to ROS1 result, and initiation of therapy prior to ROS1 result. RESULTS Among 11,409 patients, documented ROS1 testing rates increased during the study period in squamous (from 30% to 48%) and nonsquamous (63% to 78%) histologies. Patients who were older, male, black, or with squamous histology, higher Eastern Cooperative Oncology Group score, recurrent disease, or history of smoking were significantly less likely to be tested. Among patients not tested for ROS1, 63% were tested for other biomarkers. Use of next-generation sequencing, older age, Hispanic/Latino ethnicity, squamous histology, de novo disease, and smoking history predicted longer time to test result post-diagnosis. Patients with delayed results were 9.7 times more likely to receive treatment prior to ROS1 test result. CONCLUSION In real-world practice, some patient subgroups may be less likely to receive timely ROS1 testing and to be identified for potential targeted therapy.

Abstract
There were many clinical studies on lung cancer in 2018. In particular, significant progress has been made in immunotherapy and targeted therapy. Whether in small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC), immune checkpoint inhibitors (ICIs) have shown good results. For patients with specific gene mutations, the new generation inhibitors also showed good results in clinical trials. In this review, we summarize the clinical trials in lung cancer in 2018 and describe the progress and prospects for lung cancer therapies.
