Abstract: BACKGROUND/AIM: Vitamin D analogs have a protective effect on carcinogenesis in humans. Since vitamin D receptor (VDR) is detected in many histotypes of cancer, this study evaluated the role of VDR expression in endometrioid carcinoma. MATERIALS AND METHODS: Tumor samples were collected from 60 patients who had undergone surgery, and the pattern of VDR expression assessed in tissue microarray (TMA) blocks of tumor samples. When VDR expression in the cytoplasm was higher than that in the nucleus, this was noted as 'displacement'. Using statistical analysis, the relationship between VDR expression and clinicopathological factors was evaluated. RESULTS: Immunohistochemical staining of nuclear VDR was as follows: Negative: 32 (53.3%); mild: 13 (21.7%); moderate: 14 (23.3%); strong: 1 (1.7%). For cytoplasmic VDR expression: Negative: 2 (3.3%); mild: 19 (31.7%); moderate: 31 (51.7%); strong: 7 (11.7%). VDR displacement was found in 42 (70%) cores. VDR displacement was significantly positively correlated with endometrioid carcinoma having lower histological grade (1, p=0.03). CONCLUSION: Displacement of VDR was significantly correlated with lower histological grade. Clinicians might be able to predict prognosis and decide therapies related to vitamin D analogs using this remarkable biomarker for endometrial carcinoma.
