Plasma Radiofrequency Ablation at Low Temperature Versus Electrocautery Block Resection at High Frequency for Localized Recurrent Nasopharyngeal Carcinoma
China500 participantsStarted 2020-06-30
Plain-language summary
This study aims at exploring whether plasma radiofrequency ablation at low temperature is associated with better survival outcome in localized recurrent nasopharyngeal carcinoma by conducting a randomized controlled trial of plasma radiofrequency ablation at low temperature versus electrocautery block resection at high frequency for localized recurrent nasopharyngeal carcinoma. If the hypothesis is confirmed, it is expected to provide a convenient choice for the surgical treatment of localized recurrent nasopharyngeal carcinoma.
