PTPN13 expression was not affected by the patients’ age, whereas it was significantly lower in cancers with high International Federation of Gynecology and Obstetrics (FIGO) tumor stage (stage 1-2 vs 3-4; p=0.05) and with suboptimal cytoreductive surgery (optimal vs suboptimal cytoreductive surgery; p=0.007) (Table 2A) (Supplementary Figure 1). This evidence concerns the gene PTPN13 and cancer.
