Relation between age and head and neck cancer recurrence after surgery: a multivariate analysis

Area of Science:

• Oncology
• Epidemiology
• Head and Neck Surgery

Background:

• Squamous cell carcinoma of the upper aerodigestive tract is increasing in young adults.
• Clinical course of head and neck cancer in youth is debated due to lack of classic predisposing factors.
• Basic science suggests young patients may have greater DNA fragility and altered immune responses.

Purpose of the Study:

• To investigate factors affecting recurrence in head and neck cancer.
• To compare recurrence rates between young and older head and neck cancer patients using multivariate analysis.

Main Methods:

• Retrospective chart review of 155 patients meeting strict criteria.
• Patients categorized into five age groups.
• Multivariate analysis (Cox proportional hazards modeling) applied to 16 clinical variables.

Main Results:

• No significantly higher likelihood of recurrence was found in the 15- to 39-year-old age group.
• Metastatic adenopathy was a significant predictor of recurrence (p = 0.034).
• A trend toward higher relative risk of recurrence was observed in middle-aged groups (p = 0.0541).

Conclusions:

• Head and neck cancer recurrence risk is not significantly higher in young adults.
• Metastatic adenopathy is a key predictor of recurrence.
• Further research on TNM staging, aneuploidy, and DNA fragility in young patients is warranted.
