Phase Ⅱ Study of Neoadjuvant Chemotherapy Followed by Concurrent Chemoradiation for Stage ⅣAB Nasopharyngeal Carcinoma

Phase ⅡStudy of Neoadjuvant Chemotherapy Followed by Concurrent Chemoradiation for Stage ⅣAB Nasopharyngeal Carcinoma

The primary objective of this study is to determine the tolerance and overall survival in patients with stage ⅣAB NPC treated with neoadjuvant chemotherapy and concurrent chemoradiation.

Secondary objectives of the study are to evaluate the distant metastases free survival, and disease-free survival of patients with stage ⅣAB treated with this regimen

Concurrent chemoradiation is the standard treatment for locally advanced NPC. The survival benefit gained from adding neoadjuvant chemotherapy to concurrent chemoradiation has never been defined. In the present trail, we hope to assess the tolerance and survival benefits of neoadjuvant chemotherapy followed by concurrent chemoradiation in patients with stage ⅣAB NPC.

Inclusion Criteria:

• Histologically proven differentiated non-keratinizing carcinoma, and undifferentiated carcinoma of the nasopharynx.
