First analysis of the National Lung Cancer Register in Spain (RTT).

e13608Background: The Spanish Lung Cancer Group (GECP) initiated a Tumor Thoracic Register (RTT) in September 2016 with the aim of evaluating accurate, basic data concerning this oncological pathol...

ANGIOMET: Analysis of the correlations between angiogenic markers and outcome in patients (p) with advanced nonsquamous NSCLC (NS-NSCLC) treated with carboplatin, paclitaxel, and bevacizumab (CPB).

e19014 Background: In NS-NSCLC CPB achieved median OS > 1 y and supported use of B. A broad range of predictive/prognostic markers explored for B use. In VEGF pathway ligands and receptors play an ...

Clinical and molecular characteristics of the patients in the liquid biopsy study in mEGFR-NSCLC in a Spanish population (OPH-1).

e21515 Background: The liquid biopsy (LB) is an important tool in the diagnostic and follow up of the patients with non-small cell lung cancer (NSCLC) and can provide big information about the mutational variability of the disease during of the treatment. Methods: We conducted a multicenter study with 200 patients with EGFR-mutated NSCLC, treated with first-line TKI therapy. We analyse the ctDNA by dPCR pre-treatment, at 8 weeks, at 7 months and at the progression of the disease (PD). Results: A total of 200 patients (60% women / 40% men) were included. The median of age was 68-year. The never smokers were 56% and 34% ex-smokers. 92% of the cases were adenocarcinomas. According to the stag…

Snps in Angiogenic Factors As Predictive Markers for Outcome in Patients (P) with Advanced Non-Squamous Nsclc (NS-NSCLC) Treated with Carboplatin, Paclitaxel (CP) and Bevacizumab (BEV). Final Results of Angiomet Spanish Lung Cancer Group Trial

ctDNA levels before treatment predict survival in non-small cell lung cancer patients treated with a tyrosine kinase inhibitor.

9542 Background: Currently there is an intense debate concerning therapeutic strategies in EGFR positive NSCLC patients with advance disease. Osimertinib is superior to standard EGFR Tyrosine Kinase Inhibitors (TKIs) as first line treatment. However, it is yet unclear whether this option is superior to sequential treatment of a 1st or 2nd generation TKI followed by osimertinib. In order to clarify this issue it is important to identify which patients are at high risk of progression disease. Methods: This is a prospective, multicentre, cross-sectional study promoted by Spanish Lung Cancer Group. 698 plasma samples from 196 advanced NSCLC patients with tumors harboring an EGFR activating mut…
