Abstract:
Objective :To evaluate the efficacy and toxicity of intratumoral H101, a E1B-deletedadenovirus, in combination with chemotherapy on patients with nasopharyngeal carcinoma.
Methods :A total of 54 patients with nasopharyngeal carcinoma were treated with H101, 5*10 viral particle per day for 5 consecutive days. PF regimen (cisplatin 20mg/mz ivgtt, qd*Sd; 5-fluorouracil 500mg m ivgtt, qd *Sd) or AF remen (adriamycin SOm m
2 iv, d 1;5-fluorouracil 500mg/mz ivgtt, qd *Sd) was administered to patients at the same time. Treatment repeated every 3 weeks, and all patients received 2 cycles of chemotherapy.
Results :Among 54 evaluable cases, the overall response rate was 77.7%,including 10 cases of CR and 32 cases of PR. Main side effects were injection site pain (20.4%)and fever (40.7%), and influenza- like symptoms (9.3%). Serious adverse events were not found in the course of treatment.
Conclusions :The study shows that the combination of genetically E1B-deleted adenovirus (H101) possessed a distinct efficacy in patients with naso-pharyngeal carcinoma, and the toxicities were lower and will tolerated.
