Study of Previously Collected Blood and Tissue Samples From Patients With Nasopharyngeal Carcinoma,Laryngeal Carcinoma and Hypopharyngeal Carcinoma

Head and neck malignant tumors, especially nasopharyngeal carcinoma in southern China with
the high incidence, its incidence, treatment, prognosis or tumor markers in serum has been a
hot research with little progress.In our study, we collect NPC-based collection including
the blood samples of laryngeal, hypopharyngeal cancer, separating serum and white blood
cells stored in -80 degrees，while tissues are frozen in liquid nitrogen and embedded in
paraffin。 Patient treatment and prognosis are combined in order to find for markers of
molecular biology used for early diagnosis, predicting prognosis and being sensitive to
chemotherapy and radiotherapy.
