Experimental: gemcitabine and cisplatin
gemcitabine 1,000 mg/m2 over 30 to 60 minutes on days 1, 8, and plus cisplatin 80 mg/m2 on day 1, every 3 weeks.
Drug: gemcitabine and cisplatin
The GP regimen consists of gemcitabine at a dose of 1,000 mg/m2 by intravenous (i.v.) infusion over 30 min on day 1 and day 8, and cisplatin 80 mg/m2 by i.v. infusion for 4 h on day 1 only
Other Name: GP
Active Comparator: 5-Fluorouracil and cisplatin
5-Fluorouracil 4,000 mg/m2 CIV over 96 hours and plus cisplatin 80 mg/m2 on day 1, every 3 weeks.
Drug: 5-Fluorouracil and cisplatin
The FP regimen consists of 5-Fluorouracil 1,000 mg/m2/day which was administered as a continuous intravenous infusion for 96 hours after completion of the cisplatin on days 1( 80 mg/m2 i.v. infusion for 4 h)
Other Name: FP
Nasopharyngeal carcinoma (NPC) is most commonly seen in Southeast Asia, especially in southern and southeastern China ,where the incidence rate has been documented between 10 and 150 cases per 100,000 population per year. NPC is a radiosensitive tumor, and radiotherapy is considered to be the treatment of choice for most cases. The 5-year survival rate (all stages) is around 50% .In other words, more than half of the NPC cases will eventually fail radiotherapy and reasons of the failure are both local relapse and remote metastasis.
For these advanced or metastatic NPC, chemotherapy is the most important therapeutics,and they are relatively responsive to chemotherapy compared to other head and neck cancers. The backbone of the treatment for recurrent/metastatic (R/M) NPC is cisplatin containing regimen, which is also regarded as the standard regimen for other squamous cell carcinoma of head and neck (SCCHN). The FP regimen is widely used in R/M NPC patients now and its response rate is around 40%-65%,but the response period is usually short and the adverse reaction is frequent and badly tolerant, which influent the treatment compliance seriously. What's more, the catheters and pumps are necessary for continuous infusion of 5-Fluorouracil, which add to the cost, immobility and inconvenience of the treatment.
Preclinical and clinical data show synergistic activity between gemcitabine and cisplatin without overlapping toxicity. Several clinical trials enrolling a minority of advanced NPC patients suggest GP regimen has promising effectiveness and well tolerated side effects, and they indicated a potential possibility that the GP regimen comes to the standard first line choice instead of the FP regimen
