[Risk factors for distant metastasis in head and neck cancer]

Area of Science:

• Oncology
• Head and Neck Surgery
• Cancer Research

Context:

• Head and neck squamous cell carcinoma (HNSCC) is a significant global health concern.
• Surgical intervention is a primary treatment modality for HNSCC.
• Predicting and preventing distant metastasis (DM) is critical for improving patient outcomes.

Purpose:

• To identify key risk factors associated with the development of distant metastasis (DM) in patients with head and neck squamous cell carcinoma (SCC) undergoing surgical treatment.
• To analyze the correlation between clinicopathological features and the incidence of DM.
• To provide insights for risk stratification and personalized treatment strategies.

Summary:

• A retrospective analysis of 253 patients with surgically treated HNSCC identified significant risk factors for DM.
• Microscopic and gross extracapsular spread, positive neck lymph node status, and advanced primary tumor staging were strongly associated with increased risk of DM.
• Patients with DM had a mean survival of 16 months post-treatment.

Impact:

• The findings highlight the importance of evaluating extracapsular spread and lymph node status in surgical HNSCC patients.
• This research can aid in refining prognostic models and guiding adjuvant therapy decisions.
• Improved understanding of DM risk factors may lead to enhanced surveillance and management protocols for HNSCC survivors.
