主　　题：S100A7 immunotherapy squamous 

摘      要：Dear Editor,In recent years,the rapid development of immunotherapy has brought survival benefits for lung squamous cell carcinoma(LUSC)patients who have rare treatment ***,there are still some patients with immunotherapy resistance,which is the root cause of the low benefit rate and disease progression of the overall population,and it is an urgent problem to be *** for tumor mutation burden,the tumor immune microenvironment(TIME)as characterized by infiltration of CD8+tumor-infiltrating lymphocytes(TILs)and PD-L1 expression has been associated with the efficacy of immune checkpoint inhibitors(ICIs).In our previous studies,we have demonstrated that psoriasin,also known as S100 calcium-binding protein A7(S100A7),not only accelerates tumor progression via the activation of the p-Erk pathway in LUSC and the p-Erk and p-FAK pathways in esophageal squamous cell carcinomas(ESCC)but also remodels the tumor microenvironment by promoting angiogenesis and M2 macrophage infiltration in ESCC.1,2 However,the role of S100A7 in the TIME and immunotherapy efficacy in LUSC remains to be elucidated.
