Concurrent Chemotherapy for the Intermediate Risk Nasopharyngeal Carcinoma In Intensity-modulated Radiotherapy Era

Phase 3

• Conditions: Nasopharyngeal Carcinoma
• Interventions: Radiation: IMRT; Drug: Cisplatin

• Registration Number: NCT02633202
• Lead Sponsor: Sun Yat-sen University

Brief Summary

Currently, concurrent chemoradiotherapy with/without sequential chemotherapy is the standard treatment modality for intermediate risk NPC (stage II and T3N0M0) according to the National Comprehensive Cancer Network guideline. However these recommendations were based on the evidence in the two-dimensional conventional radiotherapy (2DCRT) era. The introduction of intensity-modulated radiotherapy (IMRT) in NPC treatment has brought substantial better treatment outcomes than 2DCRT. It has been questioned whether additional concurrent chemotherapy is still necessary for intermediate risk NPC within the excellent framework of IMRT. Thus, the investigators jointly conduct the first non-inferior randomized trial to determine the value of concurrent chemotherapy with cisplatin for intermediate risk NPC patients treated with IMRT. Given the results of clinical studies mentioned above,the investigators decide to adopt the concurrent regimen to be cisplatin 100 mg/m2 on day 1, 22, 43

Arm && Interventions

Group	Intervention	Description
RT group	IMRT	intensity modulated-radiotherapy (IMRT) alone: Patients receive intensity modulated-radiotherapy (IMRT) alone
CCRT group	IMRT	IMRT and concurrent cisplatin Patients receive intensity modulated-radiotherapy (IMRT), concurrently with cisplatin 100 mg/m² every 3 weeks for 3 cycles
CCRT group	Cisplatin	IMRT and concurrent cisplatin Patients receive intensity modulated-radiotherapy (IMRT), concurrently with cisplatin 100 mg/m² every 3 weeks for 3 cycles

Primary Outcome Measures

Name	Time	Method
Failure-free survival	3 Year	The failure-free survival rate will be estimated using the Kaplan-Meier method for each arm from the date of randomization to the date of treatment failure or death from any cause, whichever is first. Their differences will be compared between treatment arms using the log-rank test.

Secondary Outcome Measures

Name	Time	Method
Overall survival	3 Year	The overall survival rate will be estimated using the Kaplan-Meier method for each arm from randomization to death from any cause. Their differences will be compared between treatment arms using the log-rank test.
Locoregional failure-free survival	3 Year	The locoregional failure-free survival will be estimated using the Kaplan-Meier method for each arm from randomization to the first locoregional failure. Their differences will be compared between treatment arms using the log-rank test.
Distant failure-free survival	3 Year	The distant failure-free survival will be estimated using the Kaplan-Meier method for each arm from randomization to the first remote failure. Their differences will be compared between treatment arms using the log-rank test.
Rates of participants with adverse events	3 Year	Acute and late toxicities will be documented according to the Common Terminology Criteria for Adverse Events version 3.0 and/or the Radiation Morbidity Scoring Criteria of the Radiation Therapy Oncology Group. Rates of the toxicities will be estimated using a binomial distribution along and will be compared using Fisher's exact test between the 2 treatment arms.
