We also observed a nonsignificant inverse association with rs889312 (MAP3K1) variant carriers [OR = 0.85 (95% CI: 0.68-1.05)] and rs1219648 (FGFR2) variant carriers [OR= 0.86 (95% CI: 0.69-1.06) and endometrial cancer risk.
Here, we show that shRNA knockdown of FGFR2 or treatment with a pan-FGFR inhibitor, PD173074, resulted in cell cycle arrest and induction of cell death in endometrial cancer cells with activating mutations in FGFR2.
The discovery of activating FGFR2 mutations in endometrial carcinoma raises the possibility of employing anti-FGFR molecularly targeted therapies in patients with advanced or recurrent endometrial carcinoma.
