However, exceptions were observed in certain cancers, including CXCR4 in CESC and adrenocortical carcinoma (ACC), as well as CCR10 in various malignancies, such as nervous system cancers, endocrine malignancies (excluding ACC), PAAD, KIRC, BRCA, CESC, UCEC, and HNSC, where these chemokine genes demonstrated a positive correlation with PEBP1/STK11 co-expression. Here, CCR10 is linked to adrenal cortex carcinoma.
