RATIONALE: Famitinib is a tyrosin-inhibitor agent targeting at c-Kit, VEGFR2, PDGFR, VEGFR3, Flt1 and Flt3. Phase I study of mono famitinib has shown that the drug's toxicity is manageable.

PURPOSE: This phase I trial is studying the safety and tolerance of concurrent chemoradiotherapy with famitinib for patients with locally advanced nasopharyngeal carcinoma.

Inclusion Criteria:

• Histologically confirmed nasopharyngeal differentiation or undifferentiation carcinoma, WHO II or III

• 18-65 years of age
• ECOG performance status of 0 or 1
• Life expectancy of more than 6 months
• At least one measurable lesion :MRI scan larger than 10 mm in diameter, malignant lymph nodes larger than 10 mm in short axis
• Female: All subjects who are not surgically sterile or postmenopausal must agree and commit to the use of a reliable method of birth control for the duration of the study and for 6 months after the last dose of test article. Child bearing potential, a negative urine or serum pregnancy test result before initiating Famitinib. Male: All subjects who are not surgically sterile or postmenopausal must agree and commit to the use of a reliable method of birth control for the duration of the study and for 6 months after the last dose of test article.
• Signed and dated informed consent. Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedure.

Exclusion Criteria:
