Recently, Positron emission tomography-CT (PET-CT) has been widely applied to examine primary region of malignant tumor and metastasis to the lymph nodes or distant organs. And sometimes, we can find other malignancy in oral cancer by PET-CT. In this paper, we evaluated the usefulness of PETCT in screening of distant metastasis or other malignancy with oral cancer. In our study, eighteen of nintyone patients with distant metastasis or secondary malignancies were detected by PET-CT. Four were detected before operation, and fourteen were detected in follow up. It is necessary to decide treatment plan and treatment order of oral cancer with distant metastasis or other malignancy. PET-CT has an effective possibility for body screening, screening for oral cancer patients, and detecting distant metastasis or secondary malignancies.
