Tumorpuriteit als prognostische en predictieve biomarker van postoperatieve radiotherapie bij stadium IIIA-N2 NSCLC

: Tumor purity (TP), the proportion of malignant cells within a tumor sample, is an important feature of the tumor microenvironment (TME). Using transcriptomic data from the Lung ART-IFCT 0503 trial, we investigated the relevance of TP and its potential to predict benefit from postoperative radiotherapy (PORT).
