Correlation between magnetic resonance diffusion-weighted imaging ADC value of endometrial stromal sarcoma and the malignant biological features

Objective:To study the correlation between magnetic resonance diffusion-weighted imaging ADC value of endometrial stromal sarcoma and the malignant biological features.Methods:A total of 34 patients with endometrial stromal sarcoma who received surgical resection in Hubei Provincial Hospital of Integrated Chinese & Western Medicine between May 2014 and August 2016 were selected as the malignant group of the research, and 58 patients with uterine fibroids who received surgical resection between August 2015 and October 2016 were selected as the control group of the research. Magnetic resonance diffusion-weighted imaging was done before operation to measure apparent diffusion coefficient (ADC value). The lesions were collected after operation to determine the expression of proliferation genes as well as estrogen and progestogen receptors.Results:Endometrial stromal sarcoma ADC value of malignant group was significantly lower than uterine fibroid ADC value of control group;CyclinD1, Rb, Sp1, Survivin, ER , ERβ, PRA and PRB protein expression in endometrial stromal sarcoma lesions of malignant group were significantly higher than those of control group while SULT1E1 protein expression was significantly lower than that of control group;CyclinD1, Rb, Sp1, Survivin, ER , ERβ, PRA and PRB protein expression in endometrial stromal sarcoma lesions of subgroup with low ADC value were significantly higher than those of subgroup with high ADC value while SULT1E1 protein expression was significantly lower than that of subgroup with high ADC value.Conclusion: Magnetic resonance diffusion weighted imaging ADC values can be used to evaluate the malignant biological behavior of endometrial stromal sarcoma.
