Abstract:
Objective To investigate the diagnostic performance of ADC value for predicting proliferation and invasiveness of cervical squamous cell carcinoma (SCC).Methods Totally 96 patients with pathologically confirmed SCC underwent preoperative conventional MRI and DWI.Mini-ADC value,mean-ADC value and mini-ADC ratio (mini-ADC/meam ADC) were measured and compared for various patient groups divided based on Ki-67 labeling index and clinicopathological characteristics.Results The mini-ADC values were significantly lower in patients with high Ki-67 expression,tumor size ≥4 cm,high FIGO staging,low pathological grade,depth of cervical stromal infiltrating ≥ 1/2,parametrial involvement,lymphovascular invasion (LVI),lymph node metastasis and perineural invasion (PNI,all P＜ 0.05).Compared with mean-ADC value and mini-ADC ratio,mini-ADC value exhibited the most effective diagnostic performance in predicting clinicopathological characteristics with the highest areas under the ROC curve and efficacy.Mini-ADC value showed negative correlation with Ki-67 index (r=-0.48,P＜0.001) as well as other clinicopathological characteristics,including tumor size,FIGO staging,pathological grading,depth of cervical stromal infiltrating,parametrial involvement,LVI,lymph node metastasis and PNI (r=-0.36,-0.34,-0.27,-0.40,-0.33,-0.60,-0.61,-0.41,respectively,all P＜0.05).Conclusion Mini-ADC value can effectively reflect the proliferation and invasiveness of cervical SCC.
