The purpose of the study is to determine the role of inherited genetic factors in the etiology of NPC and to examine the effect of these genetic susceptibility factors on risk associated with environmental exposures. A family history questionnaire will be administered to the proband and other affected family members from each of the families selected for study. In addition, a risk factor questionnaire will be administered to all participating family members, and 30-40ml of blood and an oral sample will be obtained from each study participant. Additional study components include medical record review to verify the diagnosis of NPC, retrieval of tumor tissue blocks as a source of DNA for study, and clinical exams on a sample of unaffected individuals to exclude the possibility of prevalent, undetected disease among family members. Oral and laryngeal cancer families will also be recruited in an attempt to elucidate genetic factors linked to the development of these two cancers.
