Immunotherapeutic Advances for NSCLC.

2021

Abstract Immunotherapy with antibodies against PD-1 or PD-L1, either alone or in combination with chemotherapy, has revolutionized treatment paradigms of non-small cell lung cancer (NSCLC) patients without oncogenic driver alterations. These agents, namely immune checkpoint inhibitors (ICIs), have also widely demonstrated a remarkable efficacy in locally advanced as well as in early-stage NSCLC. Assessment of tumor PD-L1 expression by immunohistochemistry has entered into routine clinical practice to select patients for immunotherapy, even though its predictive role has long been debated. Despite improved survival outcomes over standard chemotherapy, treatment with ICIs is associated with i…

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

2020

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…

Prognostic value of CTCs in advanced NSCLC patients treated with platinum-based chemotherapy

2019

Abstract Background Lung cancer is the leading cause of cancer-related mortality worldwide. At diagnosis, 70% of patients present advanced disease being chemotherapy the standard of care. Although, specific tumour biomarkers that allow a better treatment selection and monitoring is absent at the moment. Enumeration and characterization of circulating tumor cells (CTCs) have the potential to perform as a prognostic biomarker for a precision medicine approach to lung cancer care. The present study was conducted to validate the characterization CTCs from patients with advanced Non-small cell lung cancer (NSCLC) as a valuable tool for anticipating the disease evolution and the therapy response.…

R-Score: A New Parameter to Assess the Quality of Variants’ Calls Assessed by NGS Using Liquid Biopsies

2021

Next-generation sequencing (NGS) has enabled a deeper knowledge of the molecular landscape in non-small cell lung cancer (NSCLC), identifying a growing number of targetable molecular alterations in key genes. However, NGS profiling of liquid biopsies risk for false positive and false negative calls and parameters assessing the quality of NGS calls remains lacking. In this study, we have evaluated the positive percent agreement (PPA) between NGS and digital PCR calls when assessing EGFR mutation status using 85 plasma samples from 82 EGFR-positive NSCLC patients. According to our data, variant allele fraction (VAF) was significantly lower in discordant calls and the median of the absolute va…

Osimertinib in first-line treatment of advanced EGFR-mutated non-small-cell lung cancer: a cost–effectiveness analysis

2019

Aim: Osimertinib improves progression-free survival in first-line EGFR mutation–positive non-small-cell lung cancer. Materials & methods: A Markov cohort model including costs, utilities and disutilities, was conducted to estimate quality-adjusted life-year (QALY) and incremental cost–effectiveness ratio when treating with osimertinib versus standard first-line tyrosine kinase inhibitors (TKIs). Results: Osimertinib presented higher QALYs (0.61) compared with standard EGFR–TKIs (0.42). Osimertinib costs were €83,258.99, in comparison with €29,209.45 for the standard EGFR–TKIs. An incremental cost–effectiveness ratio of €273,895.36/QALY was obtained for osimertinib. Conclusion: Osimerti…
