OBJECTIVE:To observe clinical efficacy and safety of tegafur gimeracil oteracil potassium combined with 3D-CRT and microwave hyperthermia in the treatment of elderly patients with local advance esophageal cancer. METHODS:48 cases of local advance esophageal cancer were divided into group A,B and C according to random number table method,with 16 cases in each group according to random number table method. Group A was given 3D-CRT with total dose of 60-66 Gy totnlly for 6-7 weeks;group B was additionally given tegafur gimeracil oteracil potassium 60 mg/(m2·d),bid,on the basis of group A 3 weeks for a course of treatment,until the end of radvotherapy;group C was additionally given thermotherapy on the basis of group B 3 weeks for a course of treatment,until the end of radvotherapy. Clinical efficacy,1-year survival rate,dysphagia,weight and KPS score were compared among 3 groups,and the occurrence of toxic reactions(radioactive esophagitis,radioactive pneumonia, bone marrow suppression and gastrointestinal reaction) were observed in 3 groups. RESULTS:Total effective rate,1-year survival rate and the remission rate of dysphagia of group C were 93.75%,87.50% and 93.75%,which were significantly higher than those of group A(50.00%,50.00% and 56.25%)and B(68.75%,68.75% and 68.75%),with statistical significance(P<0.05). There was no statistical significance in the rate of weight gain and KPS score gain among 3 groups(P>0.05). The incidence of radioactive esophagitis and radioactive pneumonia in group C were significantly lower than in group A and B,with statistical significance(P<0.05);there was no statistical significance in the incidence of gastrointestinal reaction and bone marrow suppression among 3 groups (P>0.05). CONCLUSIONS:Tegafur gimeracil oteracil potassium combined with 3D-CRT and microwave hyperthermia in the treat-ment of elderly patients with local advance esophageal cancer further improves clinical efficacy and survival rate,but shows low inci-dence of toxic reaction.

Objective To investigate the clinical effectiveness of chemoablation for the treatment of lumbar disc herniations (LDH) to provide reference for its clinical treatment .Methods A total of 191 cases of LDH were divided into the group A and B . All cases were performed the CT-guided chemoablation for treating LDH .The group A conducted the intra-disc injection treatment , while the group B conducted the intra-disc and extra-disc combined injection .The cases were followed up by the modes of outpatient department or telephone on postoperative 30 ,90 ,180 d .The follow up and statistical analysis were conducted by referring to the Macnab effect evaluation criteria .Results The two groups conducted the outpatient department follow up or telephone follow up on postoperative 30 ,90 ,180 d .All cases did not appear the complications such as nerve damage ,spinal cord damage and intervertebral disc infection .In the intra-group comparison ,the VAS score had statistical difference between before and after treatment ( P<0 .05) .In the inter-group comparison ,the score after treatment in the group B was lower than that in the group A (P<0 .05) .The good effect rate on postoperative 30 d in the group A was 81 .1% (77/95) ,which on postoperative 90 d was 83 .2% (79/95) and which on postoperative 180 d was 85 .3% (81/95) .The good effect rate in the group B was 85 .4% (82/96) on 30 d ,88 .5% (85/96) on 90 d and 91 .7% (88/96) on 180 d .Conclusion CT-guided lumbar intervertebral disc minimally invasive interventional chemoab-lation has good and rapid analgesic effect ,and the intra-disc and inter-disc combined treatment has better curative effect .
