Abstract
Objective:
This study aims to evaluate the diagnostic value and treatment implications of the head and abdomen segments in PET/CT scans for patients diagnosed with head and neck squamous cell carcinoma (HNSCC). We seek to determine if these areas should be routinely included when performing PET/CT scans focused on the neck and chest.
Materials and Methods:
We analyzed patients with confirmed HNSCC who underwent comprehensive PET/CT scans to check for metastases in the head, chest, and abdomen. Medical records were assessed to ascertain whether findings in the head and abdomen influenced clinical management beyond those identified in the neck and chest regions.
Results:
The study included 598 patients who underwent a total of 1625 PET/CT scans, all of which encompassed the head, neck, and chest. Of these, 542 patients (91%) underwent scans that also included the abdomen. Notably, only two patients (0.3%) presented with distant calvarial metastases, which did not alter their treatment plans. Twelve patients (2.2%) exhibited abdominal metastases, with 10 of those (1.8%) experiencing changes in management due to abdominal findings. Thoracic metastases were detected in 82 patients (13.7%). The incidence of distant metastases to the head and abdomen among patients with thoracic metastases was 12.2% (10 out of 82), whereas it was only 0.8% (4 out of 460) in patients without thoracic involvement.
Conclusion:
Based on our findings, there is no justification for routinely extending PET/CT scans to include the head and abdomen for HNSCC patients. For individuals without thoracic metastases, PET/CT scans should focus solely on the neck and chest.

To Summarize:
Routine inclusion of the head and abdomen in PET/CT scans for head and neck squamous cell carcinoma appears unnecessary, particularly in patients without thoracic metastases. For optimal management, focusing on the neck and chest alone may suffice.
