Aims: The Lynch syndrome (LS) screening algorithm requires BRAF testing as a fundamental step to distinguish sporadic from LS-associated colorectal carcinomas (CRC). BRAF testing by immunohistochemistry (IHC) has shown variable results in the literature. Our aim was to analyse concordance between BRAF(V600E)IHC and BRAF molecular analysis in a...

Background: The demonstration of EGFR T790M gene mutation in plasma is crucial to assess the eligibility of Non Small Cell Lung Cancer (NSCLC) patients, who have acquired resistance to first or second generation Tyrosine Kinase Inhibitors (TKIs), to receive a subsequent treatment with osimertinib. Since circulating tumor DNA (ctDNA) is present...

Background: Universal screening of colorectal cancer (CRC) patients for Lynch syndrome (LS) through MisMatch Repair (MMR) testing is recommended. BRAF V600E mutation and/or MLH1 promoter methylation (Reflex Testing, RefT)generally rule out LS in MLH1-deficient (dMLH1) patients. We estimated the impact of RefTon genetic counseling (GC) and on...

Background: Molecular characterization is pivotal for managing non-small cell lung cancer (NSCLC), although this process is often time-consuming and patients' conditions might worsen while molecular analyses are processed. Our primary aim was to evaluate the performance of "up-front" next-generation sequencing (NGS) through liquid biopsy (LB)...

Purpose: In estrogen receptor-positive (ER+) breast cancer (BC), single-nucleotide polymorphisms (SNPs) in the aromatase gene might affect aromatase inhibitors (AIs) metabolism and efficacy. Here, we assessed the impact of SNPs on prognosis and toxicity of patients receiving adjuvant letrozole. Experimental design: We enrolled 886...
