Clinical Trial of Treatment of Laryngeal Cancer by Recombinant Adenovirus P53 Combined with Chemotherapy

OBJECTIVE:To evaluate the effectiveness of recombinant adenovirus p53 injection (rAd2p53) combined with cisplatin plus 5-fluorouracil regimen in treating laryngeal carcinoma.METHOD:Tumour animal models were established in the back of mice with Hep-2 cell line. Recombinant adenovirus p53 injection (rAd2p53) were transduced to tumor-bearing mouse by direct intratumoral injection combine with cisplatin plus 5-fluorouracil ivgtt. The control group 1 was given recombinant adenovirus p53 injection (rAd2p53) simplex. The control group 2 was administered with cisplatin plus 5-fluorouracil ivgtt simplex. Then compare the diameters of pro-treatment with that of post-treatment and test group with controls.RESULT:Tumor growth was significantly inhibited following combined rAd2p53 gene therapy with cisplatin plus 5-fluorouracil chemotherapy compared to single rAd2p53 gene therapy and cisplatin plus 5-fluorouracil chemotherapy controls.CONCLUSION:Local injection of rAd2p53 combined with cisplatin plus 5-fluorouracil chemotherapy is a promising treatment to laryngeal cancer.
