Notably, we found that in general, cancers of gynaecological origin (Cervical squamous cell carcinoma and endocervical adenocarcinoma, CESC; Ovarian serous cystadenocarcinoma, OV; and Uterine Carcinosarcoma, UCS) display the highest BC-CCS levels and Head and Neck squamous cell carcinoma (HNSC), Kidney Chromophobe (KICH) and Kidney renal papillary cell carcinoma (KIRP) the lowest (Fig. 3b). This evidence concerns the gene CCS and breast cancer.
