Impact Of PET/CT On Treatment In Patients With Head And Neck Squamous Cell Carcinoma

Area of Science:

• Oncology
• Radiology
• Nuclear Medicine

Background:

• Positron emission tomography/computed tomography (PET/CT) is recognized for its effectiveness in staging head and neck squamous cell carcinoma (HNSCC).
• However, its precise impact on patient management and treatment decisions remains a subject of ongoing clinical discussion.
• This study aimed to clarify the role of PET-FDG imaging in conjunction with CT for HNSCC staging and management.

Purpose of the Study:

• To evaluate the impact of integrated PET/CT and CT imaging on the therapeutic management of HNSCC patients.
• To determine if discrepancies between CT and PET/CT diagnoses influence treatment strategies.
• To assess the overall benefit of adding PET/CT to conventional imaging for HNSCC staging.

Main Methods:

• A retrospective analysis was conducted on 169 HNSCC patients who underwent both CT and PET/CT scans within a 30-day interval.
• The study assessed treatment changes resulting from diagnostic discrepancies between the two imaging modalities.
• Data focused on how imaging findings influenced treatment selection and therapeutic intent.

Main Results:

• The combined use of CT and PET/CT resulted in a change of treatment for 39.7% of the patients (67 out of 169).
• In 27.2% of cases, the combined imaging led to a change in the specific type of treatment administered.
• A smaller proportion, 3.0% of cases, experienced modifications in the overall therapeutic intention due to the integrated diagnostic approach.

Conclusions:

• The integration of PET/CT with conventional imaging methods enhances the accuracy of HNSCC staging.
• Utilizing PET/CT alongside CT supports more informed and appropriate therapeutic decision-making for HNSCC patients.
• This multimodal imaging approach contributes to improved patient management strategies in HNSCC care.
