Clinical Trial 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. hus, we 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, we decide to adopt the concurrent regimen to be cisplatin 100 mg/m2 on day 1, 22, 43

Description:

Patients Patients with non-keratinizing NPC T1-2N1M0/T2-3N0M0 (UICC/AJCC 7th edition) are randomly assigned to receive CCRT or RT alone. Patients in CCRT group receive cisplatin 100 mg/m² every 3 weeks for 3 cycles, concurrently with intensity-modulated radiotherapy (IMRT). IMRT is given as 2.0-2.30 Gy per fraction with five daily fractions per week for 6-7 weeks to a total dose of 66 Gy or greater to the primary tumor. Our primary endpoint is failure-free survival(FFS). Secondary end points include overall survival (OS), locoregional failure-free survival (LR-FFS), distant failure-free survival (D-FFS) rates and toxic effects. All efficacy analyses are conducted in the intention-to-treat population, and the safety population include only patients who receive their randomly assigned treatment.

Prior malignancy except adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer. Pregnancy or lactation (consider pregnancy test in women of child-bearing age and emphasize effective contraception during the treatment period). History of previous RT (except for non-melanomatous skin cancers outside intended RT treatment volume). Prior chemotherapy or surgery (except diagnostic) to primary tumor or nodes. Any severe intercurrent disease, which may bring unacceptable risk or affect the compliance of the trial, for example, unstable cardiac disease requiring treatment, renal disease, chronic hepatitis, diabetes with poor control (fasting plasma glucose > 1.5×ULN), and emotional disturbance.
