Lung cancer has a high mortality rate; however, treatment with tyrosine kinase inhibitors targeting specific molecular alterations has significantly improved the survival of patients with advanced or metastatic non-small cell lung carcinoma (NSCLC). EGFR mutations are present in approximately 15% of NSCLC cases. Osimertinib was approved in Portugal by Infarmed (Portuguese Medicines Agency) in 2021 as a first-li...
Background: EGFR mutation is the most frequent in Non-Small Cell Lung Cancer and occurs mainly in women and non-smoking patients. Clinical case: We present the case of a 51-year-old female, former light smoker, diagnosed with lung adenocarcinoma in 2014, in stage IB. She underwent surgery and adjuvant therapy. She recurred after two years with metas-tatic lung and bone disease, with EGFR exon 21 mutation. Thera...
Background: Liquid biopsy allows the identification of targetable cancer mutations in a minimally invasive manner. In patients with advanced non-small cell lung cancer (NSCLC), droplet digital PCR (ddPCR) is increasingly used to genotype the epidermal growth factor receptor (EGFR) gene in circulating cell-free DNA (cfDNA). However, the sensitivity of this method is still under debate. The aim of this study was ...
