Nasopharyngeal cancer review is not a mandatory review option. Whether or not to do petct depends on the presence of new lesions and signs strongly suggestive of systemic metastasis.
For patients with nasopharyngeal cancer, the items that generally need to be regularly reviewed are ct examination of nasopharynx, nasopharyngoscopy, ultrasound of cervical lymph nodes, etc. If there is positive antibody to EBV, the titer needs to be monitored, and petct is not a necessary test for review.
CT has greater difficulty in identifying recurrence and scarring of nasopharyngeal cancer, with high false positives and poor specificity. While PET-CT is a single injection for whole body imaging, utilizing PET-CT fusion image to fuse the high metabolic parts of the lesion with CT, it can very clearly show the recurrence of the lesion as well as the metastatic location and range of the lesion to supplement the insufficiency of other examinations.
Nasopharyngeal cancer patients are recommended to undergo regular checkups and can follow the doctor’s instructions to decide whether they need to undergo PETCT in order to fully understand the disease information.
