Summary
Brief summary
Extranodal extension (ENE) refers to the spread of head and neck squamous cell carcinoma
(HNSCC) outside the lymph nodes. It is a well-known factor that indicates a poorer prognosis
and outcome for patients who have undergone surgical removal of the cancer. In such cases, it
is recommended to combine chemotherapy with radiation therapy after surgery.

As the number of cases of HNSCC related to the human papillomavirus (HPV) is increasing,
treatment approaches have shifted towards using radiation therapy as the primary treatment
method instead of surgery. This raises an important question about the significance of ENE
observed through imaging tests (referred to as iENE) and its impact on the prognosis.
Unfortunately, this question remains unanswered.

The objective of this project is to conduct a comprehensive study across multiple medical
institutions. The investigators will gather data including scan results, histopathology
reports, and data from patient charts from individuals who have been treated for head and
neck cancer. The aim is to analyze and correlate the findings between the pathological
evidence of ENE and the imaging results, while also assessing the prognostic value of iENE.
Additionally, the investigators will explore the influence of HPV status on these factors.

By collecting and analyzing this data, the investigators hope to establish standardized
criteria that can assist radiologists in accurately identifying ENE through imaging tests.
This research is essential for enhancing our understanding of HNSCC and improving the
effectiveness of diagnostic procedures and treatment planning.
