STING1 and nonpapillary renal cell carcinoma: A relationship between high STING expression and unfavorable tumor phenotype or poor prognosis has been found in SQCC of the tongue [16] and—in agreement with our data—in ccRCC [23] and adenocarcinoma of the colon [20], while associations between low STING expression and poor prognosis were described in non-small cell lung carcinoma [27], gastric cancer [15], small cell lung carcinoma [28], and head and neck carcinomas [25].
