Abstract:
Objective To investigate the correlation between DWI value of cervical cancer in stage Ib1-II A2 and its pelvic lymph node metastasis. Methods 103 patients with cervical cancer of stage Ib1 - IIa2 confimed by surgery and pathology in our hospital from January 2014 to July2016 were retro-spectively studied,78 cases of cervical squamous cell carcinoma group(lymph node metastasis of 22 cases,non- lymph node metastasis 56 cases);25 cases of Cervical adenocarcinoma group(9 cases with lymph node metastasis,16 cases of no lymph node metastasis). All patients with preoperative were performed MR routine scan and DWI examination. The ADC value(meanADC,minADC and maxADC)between the two groups and between the groups with and without metastasis were statistically analyzed. Results The value of ADC staging of cervical carcinoma had no correlation with clinical FIGO stage(Pmean = 0.847、Pmin = 0.393、Pmax = 0.219). The meanADC values、minADC value、maxADC value[(0.84 ± 0.09)× 10-3mm2/s、(0.78 ± 0.09)× 10-3mm2/s、(0.86 ± 0.07)× 10-3 mm2/s]of Squamous cell carcinomas was lower than that of adenocarcinoma[(0.98 ± 0.04)× 10-3mm2/s、(0.93 ± 0.09)×10-3mm2/s、(0.97 ± 0.23)× 10-3mm2/s]and the difference was statistically significant(P <0.05). The meanADC values and minADC value of cervical cancer within each group in lymph node metastasis group was lower than that of non- lymph node metastasis group,the difference was statistically significant(P <0.05). The maxADC value had no significant difference(P > 0.05). Conclusion The ADC value of cervical cancer has some correlation with lymph node metastasis,which can be helpful to predict the risk of lymph node metastasis.
