ABSTRACT
OBJECTIVE To study the radiose-nsitization by Topotecan on human nasopharyngeal carcinoma in nude mice. METHODS ①To study the maximum tolerance dose of TPT and detect the effective rate of TPT and RT on nude mice. ② Plan of radiosensitization practice53 nude mice xenografts were distributed to 5 groupsRT 20 Gy group,RT 40 Gy group,TPT 12.5 mg/kg group,TPT 12.5 mg/kg+RT 20 Gy group and the controlgroup. After treatment,the volume of tumors were measured every 3 days in order to value the effective rate [complete remission(CR) + partial remission(PR) ]and regrowth delay time(TGD) and to fit the growth curve. RESULTS This study showed that the effective rates had significant difference among RT20 Gy+TPT 12.5 mg/kg group,RT20 Gy group and TPT12.5 mg/kg group,while that of RT20 Gy +TPT 12.5 mg/kg group and RT40 Gy group had no statistical difference. SER reached to 1.34. CONCLUSION Topotecan has been shown a radiosensitizing effect on human nasopharyngeal carcinoma in vivo.
