In breast cancer, KIF20A predicted a poor prognosis and was an independent prognostic factor [25], as well as in bladder cancer [24], cervical squamous cell carcinoma [30], epithelial ovarian cancer [31], gastric cancer [32], glioma [7], medulloblastoma [33], melanoma [34], nasopharyngeal carcinoma [35], and ovarian clear-cell carcinoma [36]. This evidence concerns the gene KIF20A and melanoma.
