Feature selection using the least absolute shrinkage and selection operator (LASSO) cox regression model. LASSO coefficient profiles of 48 variables against the log (Lambda) sequence and tuning parameter selection in the LASSO model used 10-fold cross-validation via minimum criteria for survival (PDAC of the head, OS (a, b), and PFS (c, d); PDAC of the body/tail, OS (e, f), and PFS (g, h)).
