Application Value Research of MRI in the Thereupetic Effect Evaluation of Neoadjuvant Therapy for Rectal Cancer in Stage T3 and T4
摘要
Abstract
Objective:To study the application value of MRI in the thereupetic effect evaluation of neoadjuvant therapy for rectal cancer in stage T3,T4.Method:40 patients who were diagnosed with rectal cancer of stage T3,T4 according to the pathological examination in our hospital from January 2013 to January 2015 were selected as the research objects.The patients’ MRI data before and after the treatment of neoadjuvant therapy were retrospectively analyzed.Result:Before the treatment of neoadjuvant therapy,13 patients’tumors were less than 5 cm,27 patients’tumors were bigger than 5 cm,the DWI of the 40 patients showed high signal,while the ADC was lower,16 patients were in stage T3 and 24 patients were in stage T4.After treating,9 patients’tumors were less than 1.0 cm,11 patients’tumors were 1.0-3.0 cm,15 patients’tumors were 3.0-5.0 cm, 5 patients’tumors were less than 5.0 cm,the DWI of the 40 patients showed low signal,while the ADC was higher than before, 4 patients were in stage T1,22 patients were in stage T2,10 patients were in stage T3 and 4 patients were in stage T4.According to the pathological staging after operation,there were 5 patients in stage T1,21 patients in stage T2,10 patients in stage T3,1 patient in stage T4a and 3 patients in stage T4b.Conclusion:MRI can effectively judge the size and stage of the tumor in rectal cancer patients of T3,T4 stage before and after the treatment of neoadjuvant therapy.关键词
