GEMA-proN is an observational, multicenter, single cohort, retrospective clinical trial. The aim of the trial is to assess the prevalence, and prognostic value of genetic molecular alterations and investigate correlations with clinicopathological features in unselected patients with histologically confirmed non-small cell lung cancer (NSCLC).
This a non- interventional, multicenter, retrospective one arm trial assessing patients with histologically confirmed diagnosis of non-small cell lung cancer (NSCLC). Patients received treatment in 18 Hellenic Cooperative Oncology Group (HeCOG)- affiliated centers in Greece between 2000 and 2020. Molecular genetic alterations, including single nucleotide variants, copy number alterations, and translocations, are detected with next generation sequencing using the ForeSENTIA® NSCLC panel developed by NIPD Genetics. The aim of the trial is to assess the prevalence and prognostic value of molecular alterations in the study population.
