Abstract：Objective To determine the value of the apparent diffusion coefficient (ADC) of magnetic resonance diffusion-weighted imaging (MRDWI) combined with squamous cell carcinoma antigen (SCC) and carcinoembryonic antigen (CEA) in the evaluation of the efficacy and prognosis of concurrent chemoradiotherapy for cervical carcinoma. Methods A total of 80 patients with cervical squamous cell carcinoma confirmed by histology or cytology in our hospital from 2013 to 2016 were included in this study. Of the 80 patients, 39 were FIGO stage ⅡB, 7 were stage ⅢA, 26 were stage ⅢB, and 8 were stage ⅠVA. MRDWI examination and SCC and CEA measurements were first performed for the patients following group assignment, and the patients were then given extrapelvic radiotherapy (45-50 Gy)+platinum-based chemotherapy plus brachytherapy (20-25 Gy) based on their conditions. MRDWI, SCC, and CEA examinations were performed again after treatment to determine the changes in ADC, SCC, and CEA. In addition, ADC, SCC, and CEA were examined in the middle stage of treatment for 40 patients. Data were analyzed using the paired t-test or ANOVA. Results The overall response rate of the 80 patients after concurrent chemoradiotherapy was 100%. No disease progression was identified in any of the patients until the end of treatment, and the overall survival time of the patients was all above 6 months. Serum SCC and CEA were reduced after treatment (P=0.000,0.000), whereas the ADC value was increased after treatment (P=0.000). The increase in ACD following the decreases in SCC and CEA after treatment (P=0.000, 0.000) was indicative of increased efficacy of the concurrent chemotherapy and radiotherapy. Conclusions MRDWI combined with SCC and CEA is highly reliable for the evaluation of efficacy and prognosis of concurrent chemoradiotherapy for cervical cancer.
