[Pre-operative radiotherapy for N0 supraglottic carcinoma: a randomized study]

Area of Science:

• Oncology
• Head and Neck Surgery
• Cancer Research

Background:

• Supraglottic squamous cell carcinoma is a significant head and neck cancer.
• Accurate staging and treatment selection are crucial for managing regional recurrence.
• The N0 neck status in early-stage disease warrants investigation into optimal therapeutic strategies.

Purpose of the Study:

• To compare the efficacy of surgery alone versus combined therapy in managing N0 supraglottic squamous cell carcinoma.
• To evaluate the impact of treatment on neck failure rates.
• To identify prognostic factors for regional recurrence in this patient cohort.

Main Methods:

• A randomized study involving 100 patients with N0 supraglottic squamous cell carcinoma.
• Patients were followed for at least 3 years.
• Treatment arms included surgery alone (56 patients) and combined therapy (46 patients).

Main Results:

• Neck failure occurred in 26% of patients treated with surgery alone and 15% with combined therapy.
• No statistically significant difference in neck failure rates was observed between the two groups (P = 0.287).
• Higher rates of neck failure were noted in patients with T4 stage supraglottic carcinoma, indicating challenges in controlling regional recurrence.

Conclusions:

• For N0 supraglottic squamous cell carcinoma, neither surgery alone nor combined therapy demonstrated a statistically significant advantage in preventing neck failure.
• T4 stage disease presents a higher risk for regional recurrence, necessitating further research into optimized treatment protocols.
• Long-term follow-up is essential for evaluating treatment outcomes in head and neck cancers.
