Determination of essential biomarkers in lung cancer: a real-world data study in Spain.

2022

Abstract Background: The survival of patients with lung cancer has substantially increased in the last decade by about 15%. This increase is, basically, due to targeted therapies available for advanced stages and the emergence of immunotherapy itself. This work aims to study the situation of biomarker testing in Spain.Patients and Methods: The Thoracic Tumours Registry (TTR) is an observational, prospective, registry-based study that included patients diagnosed with lung cancer and other thoracic tumours, from September 2016 to 2020. This TTR study was sponsored by the Spanish Lung Cancer Group (GECP) Foundation, an independent, scientific, multidisciplinary oncology society that coordinate…

Comprehensive cross-platform comparison of methods for non-invasive EGFR mutation testing : results of the RING observational trial

2020

Plasma samples from 72 EGFR‐mutant advanced NSCLC patients, collected upon progression to first‐line TKI, were analyzed by seven methodologies (two NGS‐based methods, three high‐sensitivity PCR‐based platforms, and two FDA‐approved methods). Our study demonstrates a good to excellent agreement between methodologies and supports the use of liquid biopsies for therapy decision‐making.

Comprehensive cross-platform comparison of methodologies for noninvasive EGFR mutation testing: Results of the RING observational trial.

2020

e21518 Background: Several platforms for non-invasive EGFR testing are currently used in the clinical setting, with sensitivities ranging from 30 to 100%. Comparison studies in prospective cohorts remain limited and reports evaluating mutant allelic fractions (MAFs) are particularly scarce. The RING observational trial (ClinicalTrials.gov identifier NCT03363139) was designed to comprehensively analyze the concordance between methodologies for EGFR mutation detection in blood. Methods: Seventy-two EGFR mutant NSCLC patients were enrolled in the trial. Plasma samples were prospectively collected at progression to first line Tyrosine Kinase Inhibitor and tested for EGFR mutations by 7 methodo…
