The expression of the others members of the INK4 family of CDKI (CDKN2B, C and D) has been less studied in ovarian cancer (Table 2) but it has been surprisingly observed that CDKN2D (p19INK4D) expression was associated with higher tumor stage and shorter patients’ survival [92], which might deserve further investigation in future studies. Here, CDKN2A is linked to ovarian cancer.
