Objective To evaluate the value of 3-dimensional conformal radiotherapy combined with Hydroxycamptothecin(HCPT) in the treatment of local advanced non-small cell lung cancer.Methods A total of 95 cases were enrolled and randomly assigned to treatment group and control group.The treatment group was treated with 3-dimensional conformal radiotherapy(3DCRT) combined with HCPT.The control group was treated with 3DCRT only.Results Response rate(CR+PR) is respectively 73.4 % and 62 %.The response rate of treatment group is higher than that of control group(P

AIM and METHODS: A study of radioimmunoimaging was carried out on Kcnming mice - uterine cervical cancer (U14) using 99mTc labeled monoclonal Au14-1 with a modified Schwartaz method. RESULTS: The bio - distribution showed that radioactivity accumulated in tumor tissue at 12h after 99mTc - Au14- 1 injection in tail vein. The uptake by tumor was 4. 12 % ID/g at 2h and 8. 79 % ID/g at 24h respectively. The tumor/non - tumor (T/NT) radiocativity ratios for organs except kidneys were ranged from 2.02 to 6.71 at 24h post - injection. The image of tumor showed at 12h and clearer at 24h after injection. CONCLUSION: The quality of tumor image was relevant to the T/NT radioactivity ratios. It was demonstrated that 99mTc- Au14-1 has a good capability of localization for tumor.
