Interestingly, in biopsies of patients with lymph node metastases (Fig. S5D, left) or patients who retrospectively developed relapse (Fig. S5D, right), more CD4+ or IL‐17+ cells represent Th17 cells in comparison with patients without metastases or relapse. The gene discussed is IL17A; the disease is metastatic malignant neoplasm in the lymph nodes.
