Abstract
BACKGROUND NTRK gene fusions have been identified in various tumors; some requiring aggressive therapy and sometimes new TRK inhibitors (TRKi). We aimed to describe a national, unselected, retrospective, multicenter cohort. RESEARCH DESIGN AND METHODS Patients were identified through the French sarcoma diagnostic laboratory at Institut Curie through samples analyzed by RT-qPCR or whole-transcriptome sequencing. RESULTS From 2001 to 2019, 65 NTRK fusion tumors were identified within 2120 analyses (3.1%): 58 by RNA sequencing (including 20 after RT-qPCR analysis) and 7 exclusively by RT-qPCR. Of the 61 patients identified, 37 patients had infantile soft tissue or kidney fibrosarcomas (IFS), 15 other mesenchymal (Other-MT) and nine central nervous system (CNS) tumors. They encompassed 14 different tumor types with variable behaviors. Overall, 53 patients had surgery (3 mutilating), 38 chemotherapy (20 alkylating agents/anthracycline), 11 radiotherapy, two 'observation strategy' and 13 received TRKi. After a median follow-up of 61.0 months [range, 2.5-226.0], 10 patients died. Five-year overall survival is, respectively, 91.9% [95%CI, 83.5-100.0], 61.1% [95%CI, 34.2-100.0] and 64.8% [95%CI, 39.3-100.0] for IFS, Other-MT, and CNS groups. CONCLUSIONS NTRK-fusion positive tumors are rare but detection is improved through RNA sequencing. TRKi could be considered at diagnosis for CNS NTRK-fusion positive tumors, some IFS, and Other-MT. TRIAL REGISTRATION Not adapted.

Prognostic Value of Neurotrophic Tyrosine Receptor Kinase Gene Fusions in Solid Tumors for Overall Survival: A Systematic Review and Meta-Analysis. JCO Precis Oncol 2023; 7:e2200651. [PMID: 37384865 PMCID: PMC10581655 DOI: 10.1200/po.22.00651] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 02/06/2023] [Accepted: 05/19/2023] [Indexed: 07/01/2023] Open
Abstract
PURPOSE Evidence suggests that neurotrophic tyrosine receptor kinase (NTRK) gene fusions in solid tumors are predictive biomarkers for targeted inhibition across a number of adult and pediatric tumor types. However, despite robust clinical response to tyrosine receptor kinase (TRK) inhibitors, the natural history and prognostic implications of NTRK fusions in solid tumors are poorly understood. It is important to evaluate their prognostic significance on survival to provide some context to the clinical effectiveness observed in clinical trials of TRK-targeted therapies. METHODS A systematic literature review was conducted in Medline, Embase, Cochrane, and PubMed to identify studies comparing the overall survival (OS) of patients with NTRK fusion-positive (NTRK+) versus NTRK fusion-negative (NTRK-) tumors. Five retrospective matched case-control studies published before 11 August 2022 were assessed for inclusion, and three were selected for the meta-analysis (sample size: 69 NTRK+, 444 NTRK-). Risk of bias was assessed using the Risk of Bias Assessment tool for Non-randomized Studies tool. The pooled hazard ratio (HR) was estimated using a Bayesian random-effects model. RESULTS In the meta-analysis, the median follow-up ranged from 2 to 14 years and the median OS was between 10.1 and 12.7 months (where reported). Comparing patients with tumors NTRK+ and NTRK-, the pooled HR estimate for OS was 1.51 (95% credible interval, 1.01 to 2.29). The patients analyzed had no previous or current exposure to TRK inhibitors. CONCLUSION In patients not treated with TRK inhibitor therapies, those with NTRK+ solid tumors have a 50% increased risk of mortality within 10 years from diagnosis or the start of standard therapy compared with those with NTRK- status. Although this is the most robust estimate of the comparative survival rate to date, further studies are required to reduce uncertainty.

Abstract
PURPOSE Larotrectinib, a highly specific tropomyosin receptor kinase (TRK) inhibitor, previously demonstrated high response rates in single-arm trials of patients with TRK fusion-positive cancer, but there are limited data on comparative effectiveness against standard-of-care (SoC) regimens used in routine health care practice, before widespread adoption of TRK inhibitors as SoC for TRK fusion-positive cancers. Matching-adjusted indirect comparison, a validated methodology that balances population characteristics to facilitate cross-trial comparisons, was used to compare the overall survival (OS) of larotrectinib versus non-TRK-inhibitor SoC. MATERIALS AND METHODS Individual patient data from three larotrectinib trials (ClinicalTrials.gov identifiers: NCT02122913, NCT02637687, and NCT02576431) were compared with published aggregate real-world data from patients with locally advanced/metastatic TRK fusion-positive cancer identified in the Flatiron Health/Foundation Medicine database. OS was defined as the time from advanced/metastatic disease diagnosis to death. After matching population characteristics, the analyses included (1) a log-rank test of equality to test whether the two groups were similar before larotrectinib initiation; and (2) estimation of treatment effect of larotrectinib versus non-TRK-inhibitor SoC. These analyses are limited to prognostic variables available in real-world data. RESULTS Eighty-five larotrectinib patients and 28 non-TRK-inhibitor SoC patients were included in the analyses. After matching, log-rank testing showed no difference in baseline characteristics between the two groups (P = .31). After matching, larotrectinib was associated with a 78% lower risk of death, compared with non-TRK-inhibitor SoC (adjusted hazard ratio, 0.22 [95% CI, 0.09 to 0.52]; P = .001); median OS was 39.7 months (95% CI: 16.4, NE [not estimable]) for larotrectinib and 10.2 months (95% CI: 7.2, 14.1) for SoC. CONCLUSION Matching-adjusted indirect comparison analyses suggest longer OS with larotrectinib, compared with non-TRK-inhibitor SoC, in adult patients with TRK fusion-positive cancer.

Abstract
The occurrence of neurotrophic tyrosine receptor kinase (NTRK) gene fusions in a wide range of tumor types presents an attractive opportunity for using a tropomyosin receptor kinase (TRK) inhibitor as cancer therapy. Recent clinical studies have demonstrated highly efficacious outcomes associated with the use of TRK inhibitors, such as larotrectinib and entrectinib in NTRK fusion-bearing cancers, in both adult and pediatric populations. While NTRK gene fusions are commonly found in some uncommon adult and pediatric malignancies, they are also found, albeit rarely, in a wide range of more common malignancies. The potential value of testing for NTRK gene fusions in practically all advanced malignancies is underpinned by the remarkable therapeutic outcomes that TRK inhibitors offer. This requirement presents practical and financial challenges in real-world oncological practice. Furthermore, different testing platforms exist to detect NTRK gene fusions, each with its advantages and disadvantages. It is, therefore, imperative to develop strategies for NTRK gene fusion testing in an attempt to optimize the use of limited tissue specimen and financial resources, and to minimize the turnaround time. A multidisciplinary task force of Singapore medical experts in both public and private sectors was convened in late 2020 to propose testing algorithms for adult colorectal tumors, sarcomas, non-small cell lung cancer, and pediatric cancers, with particular adaptation to the Singapore oncological practice. The recommendations presented here highlight the heterogeneity of NTRK-fusion positive cancers, and emphasize the need to customize the testing methods to each tumor type to optimize the workflow.

The potential long-term comparative effectiveness of larotrectinib vs standard of care for treatment of metastatic TRK fusion thyroid cancer, colorectal cancer, and soft tissue sarcoma.

Abstract
BACKGROUND: Larotrectinib is approved for patients with metastatic TRK fusion cancers, including differentiated thyroid (DTC), colorectal cancer (CRC), and soft tissue sarcoma (STS). Given the basket clinical trial design of larotrectinib, direct comparisons against standard of care in each of the mentioned cancers have not been assessed. Also, owing to the limited duration of follow-up in clinical trials, long-term outcomes for treatments are generally not known or estimated. OBJECTIVE: To compare expected life-years (LYs) and quality-adjusted life-years (QALYs) for patients with metastatic DTC, CRC, and STS who are eligible to receive larotrectinib against patients with unknown NTRK gene fusion status receiving standard-of-care therapy. METHODS: We developed a partitioned survival model to estimate the long-term comparative effectiveness of larotrectinib and standard of care for 3 tumor types. Larotrectinib survival data, assessed by independent review committee, were derived from an updated July 2020 analysis of 19, 8, and 23 adult patients (aged ≥ 18 years) with metastatic TRK fusion DTC, CRC, and STS, respectively. The DTC survival data also included 2 patients aged less than 18 years for a total of 21 patients. Survival estimates for standard of care were derived from published clinical trials. Progressionfree and overall survival for all treatments were estimated using survival distributions (Exponential, Weibull, Log-logistic, and Lognormal) fit to the available data. The final exponential form was selected based on goodness-of-fit and clinical plausibility. QALYs were estimated by adjusting the time spent in the preprogression and postprogression health states by utility weights derived from publicly available literature. RESULTS: Patients receiving larotrectinib experienced more LYs and QALYs compared with those receiving standard-of-care treatments across all 3 assessed cancer types. In DTC, patients receiving larotrectinib had 7.15-8.26 additional LYs (5.87-6.12 QALYs); in CRC, patients receiving larotrectinib had 1.26-1.27 additional LYs (1.00 QALYs); and in STS, patients receiving larotrectinib had 5.56 additional LYs (1.99 QALYs). CONCLUSIONS: Compared with standard of care in metastatic TRK wild-type cancers, larotrectinib is estimated to result in improved LY and QALY outcomes based on parametric extrapolations of intrial survival data. Because patient-level data were unavailable for adjusted analyses, a cross-trial comparison was performed. Given the limitations of this analytic approach and the small sample size for larotrectinib in trials, future studies should reassess the comparative effectiveness of larotrectinib vs standard of care as treated patients accrue and long-term survival data mature.
