In order to detect possible associations between PTC cases in terms of MET gene output, clinical parameters were retrieved, including age at diagnosis, date of diagnosis, gender, tumor size, eventual lymph node metastases, eventual distant metastases, BRAF V600E mutation status and TERT promotor mutation status, disease-free survival (endpoints: relapsed/progression or disease-free) and overall survival (endpoints: dead or alive). The gene discussed is MET; the disease is neoplasm.
