The Role of Concurrent Chemotherapy for Lower Risk Locally Advanced Nasopharyngeal Carcinoma(NPC) in the Era of IMRT
Study Details
Study Description
Brief Summary
The purpose of this study is to verify that simultaneous integrated boost IMRT (SIB-IMRT) alone is non-inferior to SIB-IMRT combined with concurrent chemotherapy for low-risk locally advanced nasopharyngeal carcinoma.

Phase 3 |
Detailed Description
-
There were several randomized clinical trials confirmed that concurrent chemoradiotherapy (CCRT) is superior to radiotherapy (RT)alone for locally advanced NPC, most of the patients in the trials were treated with conventional radiotherapy technique.
-
As the new technique of IMRT used more and more in the clinical practice, the role of concurrent chemoradiotherapy (CCRT) seems blurred, in two of Hongkong phaseIII studies(NPC9901/9902), half of the patients were treated by 3-dimensional conformal radiotherapy (3DCRT)/IMRT,the results showed that there were no significant different in terms of overall survival between RT alone and CCRT groups. Furthermore, several large sample size retrospective studies from China, showed that there were no advantage of CCRT over RT alone when treated by SIB-IMRT.
-
In an analysis of who will benefit from CCRT,( Lin, et.al, IJROBP,2004; 60:156-164), the author divided the locally advanced NPC patients into two groups, with the high-risk group defined as patients met at least one of following criteria: nodal size >6 cm, (2) supraclavicular node metastasesN3, T4N2 and multiple neck node metastases with 1 node
4cm.
- Based on these information, we hypothesize that, for low-risk locally advanced NPC patients, there may no need CCRT under SIB-IMRT treatment.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: RT alone SIB-IMRT was given to the patients with a regimen of 69.96Gy-73.92Gy to the gross target volume, 60Gy to the high risk clinical target volume, 50Gy to the low risk clinical target volume |
Radiation: SIB-IMRT
SIB-IMRT was given to the patients with regimen of 69.96Gy-73.92Gy to the gross target volume, 60Gy to the high risk clinical target volume, 50Gy to the low risk clinical target volume
|
| Active Comparator: CCRT group SIB-IMRT was given to the patients with regimen of 69.96Gy-73.92Gy to the gross target volume, 60Gy to the high risk clinical target volume, 50Gy to the low risk clinical target volume and cisplatin 100mg/m2 was given at d1, d22,d43 during radiotherapy. |

Outcome Measures
Primary Outcome Measures
- overall survival [5 years]
according to the recruitment, a interrim analysis will done in July, 2019, if there is inferior finding of RT alone group, the study will premature terminate
Secondary Outcome Measures
- Acute and late toxicities [5years]
compare the acute radiation and chemotherapy-related toxicities during treatment course compare late toxicities after treatment
- 3 year Progression-free survival (PFS) [5year]
to compare the 3years PFS between the IMRT alone and IMRT with concurrent chemoradiotherapy
Eligibility Criteria
