There were no significant differences in the transcriptional expression of PIM-1 according to sex (P = 0.941), age (P = 0.060), toxics consumption (P = 0.301), location of the primary tumor (P = 0.092), local (P = 0.326) or regional (P = 0.896) extension of the tumor, or histological grade (P = 0.781). Here, PIM1 is linked to neoplasm.
