Can undifferentiated non-keratinizing nasopharyngeal carcinoma be cured?

Undifferentiated non-keratinizing nasopharyngeal carcinoma refers to obvious lymphocyte infiltration in most tumor stroma, vacuolar cancer cells and smooth nuclear membrane. At present, it cannot be cured because the cancer cells are small and the cytoplasm is less diffuse, so radiotherapy or chemotherapy is needed to control the spread of cancer cells and prolong the survival period.
