Intensity-modulated Radiotherapy With or Without Concurrent Chemotherapy for Stage II Nasopharyngeal Carcinoma

Summary

A prior phase III randomized trial showed considerable survival benefit from the combined treatment of cisplatin-based concurrent chemotherapy and two-dimensional conventional radiotherapy (2DCRT) for patients with stage II (the Chinese 1992 staging system) nasopharyngeal carcinoma. However, since intensity-modulated radiotherapy (IMRT) was known to be superior to 2DCRT in local control, progression free survival and even overall survival, it is a pivotal question whether stage II \[T1N1M0 and T2N0-1M0, based on the 2010 International Union against Cancer/American Joint Committee on Cancer (UICC/AJCC) staging system\] patients can still obtain significant benefit from the additional concurrent chemotherapy in the IMRT era. The investigators' retrospective study (PMID:26528755 ) indicated that low risk nasopharyngeal carcinoma (T1N1M0, T2N0-1M0 or T3N0M0, the 2010 UICC/AJCC staging system) patients who underwent IMRT could not benefit from cisplatin-based concurrent chemotherapy. Therefore, the investigators perform this randomized controlled trial to address this question, on a prudent assumption that IMRT alone was not inferior to IMRT plus concurrent chemotherapy in stage II patients.
