Survival study and treatment strategy for second primary malignancies in patients with head and neck squamous cell carcinoma and nasopharyngeal carcinoma

Abstract

The survival rate of patients with SPMs is not significantly poor. The survival is worse if the SPM is associated with a primary advanced stage index cancer or it is synchronous; if the SPM occurs in an area other than the head and neck region; or if SPM patients undergo palliative treatment.
