In cancer patients, survival and lymph node metastasis are independently predicted by the frequency of lymphocytes infiltrating into the tumour.39, 40, 41 As such, we next explored the relationship between TGFβ2 expression and the degree of immune cell infiltration into 39 tumour types using the TIMER database (Figure S2). Here, TGFB2 is linked to metastatic malignant neoplasm in the lymph nodes.
