[PMID: 36932463 DOI: 10.1080/03007995.2023.2192610] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Accepted: 03/14/2023] [Indexed: 03/19/2023]
Abstract
OBJECTIVE Time To Discontinuation (TTD) is defined as the time from the start of treatment to the end of treatment, usually occurring due to loss of efficacy or occurrence of adverse events. It has become an important surrogate efficacy endpoint especially in real-world studies due to its correlation with endpoints such as Progression Free Survival (PFS). The aim of the study is to conduct a literature review of all studies reporting TTD in first-line therapy of Non-Small Cell Lung Cancer (NSCLC). METHODS All articles that reported TTD for any first-line treatment of NSCLC as of 30 June 2022 were extracted from the PubMed search engine. From these articles, the drugs, study type, and TTD values were extracted. A descriptive analysis of the studies was made, dividing the TTD by subgroup according to the type of treatment (traditional chemotherapy, target therapy, immunotherapy) and study design (clinical trials, real world studies). RESULTS Fifty-five studies were considered for the analysis, of which 12 were published in 2021; 28 were clinical trials and 27 were real-world studies. Thirty of the studies considered involved conventional chemotherapy and expressed TTD values from 1.4 to 4.5 months, 5 of the studies considered involved immunotherapy with TTD values from 2.1 to 7.4 months and 18 of the studies considered target therapy, with TTD values from 4 to 31 months. The clinical trials reported TTD values from 1.4 to 16 months and the real-world studies from 2 to 31 months. CONCLUSION Studies reporting TTD are increasing, most notably real-world studies. Given the increasing importance of TTD as an efficacy endpoint, it becomes critical to measure and monitor it in various therapeutic settings such as NSCLC. This is the first study to review all TTD values of drugs used in first-line NSCLC.

Healthcare coverage affects survival of EGFR-mutant Thai lung cancer patients. Front Oncol 2023; 13:1047644.

Abstract
Background Despite significant benefits of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) treatment in patients with EGFR-mutated NSCLC, access remains limited in Thailand and elsewhere. Methods Retrospective analysis of patients with locally advanced/recurrent NSCLC and known EGFR mutation (EGFRm) status treated at Ramathibodi Hospital (2012-2017). Prognostic factors for overall survival (OS), including treatment type and healthcare coverage, were analyzed using Cox regression. Results Of 750 patients, 56.3% were EGFRm-positive. After first-line therapy (n=646), 29.4% received no subsequent (second-line) treatment. EGFR-TKI-treated EGFRm-positive patients survived significantly longer than EGFRm-negative patients without EGFR-TKIs (median OS [mOS] 36.4 vs. 11.9 months; hazard ratio HR=0.38 [95%CI 0.32-0.46], P<0.001). Cox regression indicated significantly longer OS in patients with comprehensive healthcare coverage that included reimbursement of EGFR-TKIs, versus basic coverage (mOS 27.2 vs. 18.3 months; adjusted HR=0.73 [95%CI 0.59-0.90]). Compared with best supportive care (BSC; reference), EGFR-TKI-treated patients survived significantly longer (mOS 36.5 months; adjusted HR (aHR)=0.26 [95%CI 0.19-0.34]), and versus chemotherapy alone (14.5 months; aHR=0.60 [95%CI 0.47-0.78]). In EGFRm-positive patients (n=422), relative survival benefit of EGFR-TKI treatment remained highly significant (aHR[EGFR-TKI]=0.19 [95%CI 0.12-0.29]; aHR(chemotherapy only)=0.50 [95%CI 0.30-0.85]; reference:BSC), indicating that healthcare coverage (reimbursement) affected treatment choice and survival. Conclusion Our analysis describes EGFRm prevalence and survival benefit of EGFR-TKI therapy for EGFRm-positive NSCLC patients treated from 2012-2017, one of the largest such Thai datasets. Together with research by others, these findings contributed evidence supporting the decision to broaden erlotinib access on healthcare schemes in Thailand from 2021, demonstrating the value of local real-world outcome data for healthcare policy decision-making.

Advanced Lung Cancer Patients' Use of EGFR Tyrosine Kinase Inhibitors and Overall Survival: Real-World Evidence from Quebec, Canada. Curr Oncol 2022; 29:8043-8073. [PMID: 36354696 PMCID: PMC9689227 DOI: 10.3390/curroncol29110636] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 10/21/2022] [Accepted: 10/24/2022] [Indexed: 11/11/2022] Open
Abstract
EGFR tyrosine kinase inhibitors (EGFR-TKIs) are breakthrough palliative treatments for advanced lung cancer patients with tumors harboring mutations in the EGFR gene. Using healthcare administrative data, three cohorts were created to describe the use of three EGFR-TKIs that are publicly funded in Quebec for specific indications (i.e., 1st-line gefitinib, 1st-line afatinib, and post-EGFR-TKI osimertinib). The main objective was to compare overall survival (OS) among patients receiving these treatments to those in previous experimental and real-world studies. The patients who received EGFR-TKIs for indications of interest between 1 April 2001, and 31 March 2019 (or 31 March 2020, for post-EGFR-TKI osimertinib) were included to estimate the Kaplan-Meier-based median OS for each cohort. An extensive literature search was conducted to include comparable studies. For the gefitinib 1st-line (n = 457), the afatinib 1st-line (n = 80), and the post-EGFR-TKI osimertinib (n = 119) cohorts, we found a median OS (in months) of 18.9 (95%CI: 16.3-21.9), 26.6 (95%CI: 13.7-NE) and 19.9 (95%CI: 17.4-NE), respectively. Out of the 20 studies that we retained from the literature review and where comparisons were feasible, 17 (85%) had similar OS results, which further confirms the value of these breakthrough therapies in real-world clinical practice.
