Clinical application of electrochemical therapy for cancerous pain

Objective: To study the effect of electrochemical therapy(EChT) in tumor treatment from Jan,2003 to Jan,2010,in 61 cases of advanced tumor with cancerous pain.Methods:Cases in this study included malignant tumors of head-neck,chest,digestive system,gynecology,bone and soft tissues.All of tumors were classified as Ⅳ stage.Pain levels were determined according to VAS Classification,and 1,20 and 37 cases were classified in the 1st,2nd,and 3rd grade respectively.After anesthesia,anode and cathode were inserted into tumors with 1-2cm interval,and electrical quantity were set up 100 coulombs per cm3.The therapeutic courses of all patients were safe and no complication.Results: All patients' cancerous pain relieved,and the effective rate was 100%.Therapeutic effect of pain: Complete response(CR) was 56 cases,partial response(PR) was 5 cases;curative effect maintained 7 days at least,and the longest was over 1 year.After treatment,all patients stopped to use morphine,dolantin and other anodynes.Conclusion: The patients who suffer from cancerous pain and suit for EChT can be treated with EChT.EChT is easy to operate,no bleeding,and little pain,and it is not only to alleviate cancer pain,but also to cure primary tumor,metastatic and relapse tumor effectively,is a new and effective method for cancerous pain,and deserve to be applied.
