摘要

Background: The optimal treatment for tonsillar squamous cell carcinoma (SCC) remains controversial. The purpose of this study was to evaluate long-term treatment outcomes of patients with tonsillar SCC, in order to aid in appropriate treatment selection. Methods: We conducted a retrospective chart review of 105 patients with curatively treated tonsillar SCC between January 1996 and December 2005. Forty-three patients (41.0%) underwent primary surgery with or without adjuvant therapy (primary surgery group), and 62 patients (59.0%) were treated with radiotherapy/chemoradiotherapy (RT/CRT, organ preservation group). Twenty patients (19%) received tumor tonsillectomy before definitive RT/CRT and were grouped into the organ preservation group. Results: No significant differences were observed between the primary surgery and organ preservation groups in terms of local control (. p = 0.212), regional control (. p = 0.684), distant metastasis (. p = 0.627), 5-year disease-specific survival (DSS, p = 0.774), and overall survival rates (OS, p = 0.667). The rates of major complication (. p = 0.216), long-term dependency on feeding tubes (. p = 0.876), and tracheostomy (. p = 0.401) were also similar. Advanced T classification (T3-4) was the only factor associated with significantly worse DSS (. p = 0.007) and OS (. p = 0.012). However, there was also no difference in final treatment outcomes in T3-4 patients regardless of whether they were treated with primary surgery or RT/CRT. In the organ preservation group, tumor tonsillectomy before RT/CRT did not improve local control (. p = 0.520) or other treatment outcomes, including 5-year DSS (. p = 0.707) and OS (. p = 0.745). Conclusion: Both primary surgery and RT/CRT organ preservation are effective treatments for tonsillar SCC. Single modality treatment, either surgery or RT/CRT, can typically be provided for stage I-II diseases. Although RT/CRT organ preservation is used more frequently for stage III-IV tonsillar SCC in recent years, primary surgery combined with adjuvant therapy still achieves equivalent outcomes. Multidisciplinary pretreatment counseling and the facilities and personnel available are therefore important for decision-making. In addition, if RT/CRT organ preservation is selected as the primary treatment, tumor tonsillectomy is not indicated.
