Abstract：
Head and neck cancers are mostly represented by squamous cell carcinoma. Despite effective treatment of primary tumours, local recurrences and metastases are frequent, with up to a 60% risk of local and 30% of distant failure. Moreover, second primary tumours sometimes occur in these patients (2-3% per year). Treatment of recurrences, metastases, and second primary tumours can be extremely challenging for Otorhinolaryngologists, especially in patients who have already been treated with radiotherapy, previous surgery, or both. Electrochemotherapy represents an effective and valid option in these cases.
