We studied the immune landscape of 11 SMARCA4-UT samples (total of 9 patients), including 4 primary thoracic tumors (2 biopsies and 2 surgical specimens) and 7 distant metastases: bone (n = 1), lymph node (n = 4), brain (n = 1), and jaw (n = 1). This evidence concerns the gene SMARCA4 and neoplasm of thorax.
