The association between tyrosine kinase inhibitors and fatal arrhythmia in patients with non-small cell lung cancer in Taiwan.

ABSTRACT:

Objective

As a standard therapy, tyrosine kinase inhibitors (TKIs) improved survival in patients with non-small cell lung cancer (NSCLC) and epidermal growth factor receptor (EGFR) mutation. However, treatment-related cardiotoxicity, particularly arrhythmia, cannot be ignored. With the prevalence of EGFR mutations in Asian populations, the risk of arrhythmia among patients with NSCLC remains unclear.

Methods

Using data from the Taiwanese National Health Insurance Research Database and National Cancer Registry, we identified patients with NSCLC from 2001 to 2014. Using Cox proportional hazards models, we analyzed outcomes of death and arrhythmia, including ventricular arrhythmia (VA), sudden cardiac death (SCD), and atrial fibrillation (AF). The follow-up duration was three years.

Results

In total, 3876 patients with NSCLC treated with TKIs were matched to 3876 patients treated with platinum analogues. After adjusting for age, sex, comorbidities, and anticancer and cardiovascular therapies, patients receiving TKIs had a significantly lower risk of death (adjusted HR: 0.767; CI: 0.729-0.807, p < 0.001) than those receiving platinum analogues. Given that approximately 80% of the studied population reached the endpoint of mortality, we also adjusted for mortality as a competing risk. Notably, we observed significantly increased risks of both VA (adjusted sHR: 2.328; CI: 1.592-3.404, p < 0.001) and SCD (adjusted sHR: 1.316; CI: 1.041-1.663, p = 0.022) among TKI users compared with platinum analogue users. Conversely, the risk of AF was similar between the two groups. In the subgroup analysis, the increasing risk of VA/SCD persisted regardless of sex and most cardiovascular comorbidities.

Conclusions

Collectively, we highlighted a higher risk of VA/SCD in TKI users than in patients receiving platinum analogues. Further research is needed to validate these findings.

Project description:Lung cancer still represents the leading cause of cancer-related mortality. However, the recent advent of tyrosine kinase inhibitors (TKI), pioneering drugs against targetable mutations, have dramatically improved prognosis of advanced non-small cell lung cancer (NSCLC) patients. Anaplastic lymphoma kinase (ALK) gene rearrangements, identified in 3-7% of NSCLC cases, reflects in the constitutive activation of downstream signalling pathways, stimulating tumour cell proliferation, differentiation and survival. To accurately detect the wide spectrum of ALK rearrangements, the introduction of innovative techniques, like reverse transcriptase polymerase chain reaction (RT-PCR) or next generation sequencing (NGS) now allows for a more precise detection of variants and a more objective reading assessment, compared to the traditional diagnostic approaches. In some occasions, these new tools may dynamically monitor tumor evolution and even guide the choice of the most appropriate ALK inhibitor. In fact, among ALK TKIs available, crizotinib was the first to receive FDA accelerate approval for ALK rearranged NSCLC patients. Notwithstanding its response rate, ranging from 57% to 74%, the majority of patients progress within the first year of drug administration, due to acquired resistance. Both ALK-dependent and independent mechanisms of acquired resistance to TKIs have been identified. If the activation of multiple bypass signaling pathways constitutes the most common ALK-independent mechanism of resistance and one of the most difficult to overcome, ALK-dependent escape strategy mainly consists of mutations in the kinase domain, where the type of mutation largely depends on the TKI administered. Second and third generation TKIs are now available and are demonstrating high systemic and central nervous system (CNS) efficacy in clinical trials. Even though appropriate timing and sequencing of these compounds are still unclear, the large number of ALK inhibitors is now a precious resource aiming to prolong progression-free survival (PFS) and finally overall survival (OS). Here Authors provide an overview of the current approaches in the clinical management of advanced NSCLC patients harboring ALK rearrangement and discuss future perspectives to address current issues, highlighting the perception that ALK-rearranged advanced NSCLC patients benefit from maintained ALK inhibition for as long as possible.

Project description:ImportanceTyrosine kinase inhibitors (TKIs) have been recognized as the standard treatment for patients with non-small cell lung cancers (NSCLCs) and epidermal growth factor receptor (EGFR) sequence variation. Although TKIs have been reported to cause cardiotoxicity, they are widely administered owing to the high prevalence of EGFR sequence variation in Taiwan.ObjectiveTo compare the outcomes of death and major adverse cardiac and cerebrovascular events among patients with NSCLC who use and do not use TKIs in a national cohort.Design, setting, and participantsUsing data from the Taiwanese National Health Insurance Research Database and National Cancer Registry, patients treated for NSCLC from 2011 to 2018 were identified, and their outcomes were analyzed, including death and major adverse cardiac and cerebrovascular events (MACCEs; such as heart failure, acute myocardial infarction, and ischemic stroke) after adjusting for age, sex, cancer stage, comorbidities, anticancer therapies, and cardiovascular drugs. The median follow-up duration was 1.45 years. The analyses were performed from September 2022 to March 2023.ExposuresTKIs.Main outcomes and measuresCox proportional hazards models were used to estimate death and MACCEs in patients treated with and without TKIs. Given that death may reduce the incidence of cardiovascular events, the competing risk method was used to calculate the MACCE risk after adjustment for all potential confounders.ResultsOverall, 24 129 patients treated with TKIs were matched with 24 129 patients who did not receive TKIs (24 215 [50.18%] were female; and the mean [SD] age was 66.93 [12.37] years). Compared with those not receiving TKIs, the TKI group presented with a significantly lower hazard ratio (HR) of all-cause death (adjusted HR, 0.76; 95% CI, 0.75-0.78; P < .001), and the reason for death was primarily cancer. In contrast, the HR of MACCEs significantly increased (subdistribution HR, 1.22; 95% CI, 1.16-1.29; P < .001) in the TKI group. Furthermore, afatinib use was associated with a significantly reduced risk of death among patients receiving various TKIs (adjusted HR, 0.90; 95% CI, 0.85-0.94; P < .001) compared with those receiving erlotinib and gefitinib, although the outcomes of MACCEs were similar between the 2 groups.Conclusions and relevanceIn this cohort study of patients with NSCLC, TKI use was associated with reduced HRs of cancer-related death but increased HRs of MACCEs. These findings suggest the importance of close monitoring of cardiovascular problems in individuals receiving TKIs.

Project description:BackgroundEpidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are the standard treatment for patients with non-small cell lung cancer (NSCLC) harboring EGFR mutations. This study aimed to evaluate the efficacy of EGFR-TKIs and prognostic factors for patients with NSCLC harboring uncommon EGFR mutations, which account for 10% of EGFR mutations.MethodsA total of 230 treatment-naive patients with NSCLC harboring uncommon EGFR mutations treated with first-line EGFR-TKIs between 2011 and 2018 at four hospitals (belonging to four institutions, Linkou, Kaohsiung, Keelung, and Chiayi, of the Chang Gung Memorial Hospital) in Taiwan were retrospectively reviewed. Their clinicopathological characteristics, adverse events (AEs), objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) were collected. Univariate and multivariate analyses were performed to identify potential prognostic factors for PFS.ResultsOverall, patients who received afatinib (n = 62) had better PFS (median: 6.4 vs. 5.9 months, p = 0.022) and OS (median: 13.4 vs. 13.0 months, p = 0.008) than those who received gefitinib/erlotinib (n = 124), although no significant differences were observed for ORR (46.8% vs. 35.5%, p = 0.137) or DCR (59.7% vs. 58.9%, p = 0.916). Patients who received afatinib showed significantly higher ORR (58.3% vs. 31.3%, p = 0.027) but not DCR compared with gefitinib/erlotinib for major uncommon mutations. Afatinib trended toward better PFS and OS for major uncommon mutations and compound mutations. No EGFR-TKIs were effective for most NSCLC patients with exon 20 insertions. Performance status, metastasis of the liver and pleura, and dose reduction were independent prognostic factors for PFS.ConclusionAfatinib demonstrated better survival outcomes than gefitinib/erlotinib for NSCLC patients harboring major EGFR uncommon mutations and compound mutations. Performance status and metastatic sites may be useful for predicting PFS for major uncommon mutations and compound mutations.

Project description:BackgroundThe Mesenchymal epithelial transition factor (MET) gene encodes a receptor tyrosine kinase with pleiotropic functions in cancer. MET exon 14 skipping alterations and high-level MET amplification are oncogenic and targetable genetic changes in patients with non-small-cell lung cancer (NSCLC). Resistance to tyrosine kinase inhibitors (TKIs) has been a major challenge for targeted therapies that impairs their clinical efficacies.MethodsEighty-six NSCLC patients were categorized into three cohorts based on the time of detecting MET tyrosine kinase domain (TKD) mutations (cohort 1: at baseline; cohort 2: after MET-TKI treatment; cohort 3: after EGFR-TKI treatment). Baseline and paired TKI treatment samples were analyzed by targeted next-generation sequencing.ResultsMET TKD mutations were highly prevalent in METex14-positive NSCLC patients after MET-TKI treatment, including L1195V, D1228N/H/Y/E, Y1230C/H/N/S, and a double-mutant within codons D1228 and M1229. Missense mutations in MET TKD were also identified at baseline and in post-EGFR-TKI treatment samples, which showed different distribution patterns than those in post-MET-TKI treatment samples. Remarkably, H1094Y and L1195F, absent from MET-TKI-treated patients, were the predominant type of MET TKD mutations in patients after EGFR-TKI treatment. D1228H, which was not found in treatment-naïve patients, also accounted for 14.3% of all MET TKD mutations in EGFR-TKI-treated samples. Two patients with baseline EGFR-sensitizing mutations who acquired MET-V1092I or MET-H1094Y after first-line EGFR-TKI treatment experienced an overall improvement in their clinical symptoms, followed by targeted therapy with MET-TKIs.ConclusionsMET TKD mutations were identified in both baseline and patients treated with TKIs. MET-H1094Y might play an oncogenic role in NSCLC and may confer acquired resistance to EGFR-TKIs. Preliminary data indicates that EGFR-mutated NSCLC patients who acquired MET-V1092I or MET-H1094Y may benefit from combinatorial therapy with EGFR-TKI and MET-TKI, providing insights into personalized medical treatment.
