CXCR2 expression was downregulated in BLCA, lymphoid neoplasm diffuse large B-cell lymphoma (DLBC), esophageal carcinoma (ESCA), head and neck squamous cell carcinoma (HNSC), lung adenocarcinoma (LUAD), skin cutaneous melanoma (SKCM), and thymoma (Thymoma) (Figure 3(b)) subjects. Here, CXCR2 is linked to carcinoma of esophagus.
