Synopsis

Single ADC value can only distinguish low-differentiated CSCC from medium-well-differentiated squamous cell carcinoma, but it cannot distinguish medium-differentiated CSCC from highly-differentiated CSCC. ADC value combined with texture features can improve the efficacy of differentiation degree of CSCC before surgery.

INTRODUCTION

To explore the value of apparent diffusion coefficient (ADC) values and texture analysis in evaluating the differentiation degree of cervical squamous cell carcinoma (CSCC).

METHODS

Totally 88 patients with pathologically confirmed CSCC were included. ALL the patients were performed routine MRI and diffusion-weighted imaging (DWI) with b=0, 1000s/mm2, and the ADC values of them were measured on postprocess workstation. Texture analysis was performed on MRI images, parts of the parameters were obtained. The results were compared by using SPSS software’s one-way ANOVA analysis and LSD, P<0.05 was statistically significant.

RESULTS

The differences between the poorly and highly differentiated groups and between poorly and moderately differentiated groups were both statistically significant (P < 0.05), while the differences between the moderately and highly differentiated groups were not statistically significant (P > 0.05). For the comparison of texture features among the three groups, there were statistically significant differences in standard deviation and entropy (P < 0.05), and there were no statistically significant differences in energy, kurtosis, mean value and skewness (P > 0.05).

CONCLUSION

Single ADC value can only distinguish low-differentiated CSCC from medium-well-differentiated squamous cell carcinoma, but it cannot distinguish medium-differentiated CSCC from highly-differentiated CSCC. ADC value combined with texture features can improve the efficacy of differentiation degree of CSCC before surgery.
