Surveillance CT scans are not recommended foir treated head and neck cancer. Multiple studies show that the routine follow-up program after treatment for laryngeal carcinoma did not lead to survival benefit for asymptomatic patients with tumor recurrence. A proven correlation between intensive follow-up and improved patient survival is lacking and should be consdiered unproven and investigtional at this time. NCCN recommend imaging of the primary site and neck within 6 months and afterwards only if clinically indicated.
