Indications for PET/CT in the head and neck

Area of Science:

• Oncology
• Nuclear Medicine
• Radiology

Background:

• Positron Emission Tomography/Computed Tomography (PET/CT) has significantly advanced head and neck cancer patient evaluation.
• Its utility spans accurate staging, targeted therapy, early recurrence detection, and identification of advanced disease.

Purpose of the Study:

• To review the literature on PET/CT applications in head and neck cancers, focusing on squamous cell carcinoma.
• To provide an evidence-based approach for PET/CT use in staging, treatment planning, response monitoring, and surveillance.
• To briefly discuss PET/CT utility in thyroid cancer, lymphoma, and melanoma.

Main Methods:

• Literature review of PET/CT applications in head and neck cancers.
• Evidence-based analysis of PET/CT for staging, treatment, and surveillance.
• Inclusion of specific cancer types: squamous cell carcinoma, thyroid cancer, lymphoma, and melanoma.

Main Results:

• PET/CT enables more accurate staging and focused treatment planning for head and neck cancers.
• It facilitates earlier detection of recurrent disease and identification of incurable cases.
• The cost-effectiveness of PET/CT requires careful consideration in specific clinical contexts.

Conclusions:

• PET/CT is a valuable tool in managing head and neck squamous cell carcinoma, impacting staging, treatment, and surveillance.
• Its application extends to other head and neck malignancies like thyroid cancer, lymphoma, and melanoma.
• An evidence-based approach is crucial for optimizing PET/CT utilization and justifying its cost.
