- Background/Aim: The majority of patients with early-stage endometrial cancer (EC) have a good prognosis, but recurrence does occur despite diagnosis at an early stage. There is a growing need for early diagnosis of EC and novel treatment options. Materials and Methods: Human epidermal growth factor receptor 2 (HER2) and vascular endothelial growth factor receptor 2 (VEGFR) expression in microarrays of patient EC tissue was examined in association with clinicopathological data. HER2 and VEGFR2 expression in Ishikawa cells and differences in migration and proliferation of cells with HER2-knockdown were evaluated. Results: Higher expression of VEGFR2 was associated with lower International Federation of Obstetrics and Gynecology grades (p=0.044). The positive correlation between HER2 and VEFR2 expression was statistically significant in T1 stage (p=0.002) and International Federation of Obstetrics and Gynecology grade 1 tumors (p=0.004). Wound-healing assays revealed that HER2 loss in Ishikawa cells reduced confluence compared to that of control cells. Conclusion: The association of VEGFR2 and HER2 expression in early EC was elucidated. This study shows that the measurement of VEGFR2 expression may be useful in the preoperative assessment of EC and suggests the possibility of anti-HER2 therapy for EC.
