Objective To discuss treatment options for tonsillar squamous cell carcinoma.Methods A total of 108 patients with biopsy-proven tonsillar squamous cell carcinoma, treated between 1984 and 2000, were reviewed, including 82 men and 26 women, with ages ranging from 19 to 70 years. Treatments consisted of either radiotherapy and surgery reserved as salvage treatment (Salvage Surgery, 83 patients), or planned surgery with preoperative radiation (Planned Surgery, 25 patients). Radiotherapy was delivered primarily in a dosage of 60 -70 Gy for Salvage Surgery patients and 40 -50 Gy for Planned Surgery patients. Both salvage and planned surgeries were radical, with resection of the lateral oropharyngeal wall, segmental resection of the mandible and neck dissection. The pectoralis major myocutaneous flaps were used to repair surgical defects.Results The percentages of radical surgery used in the Salvage Surgery and Planned Surgery groups were 24. 1% (20/83) and 88. 0% (22/25), respectively ( P = 0. 000). The local recurrence rates were 28. 9% (24/83) and 20. 0% (5/25) in the Salvage Surgery and Planned Surgery groups, respectively ( P = 0. 378). The neck recurrence rates were 9. 6% (8/83) and 8. 0% (2/25) in the Salvage Surgery and Planned Surgery groups respeatively ( P = 0. 804) . The 5-year survival rates were 59. 3% and 55.3% in the Salvage Surgery and Planned Surgery groups, respeatively (P= 0.7056).Conclusions Although the two treatments had a similar survival rate, Salvage Surgery avoided 60% commando operations compared with the Planned Surgery group, which benefits to recovery of oral functions. Primary radiotherapy is recommended as the treatment of choice for tonsillar squamous cell carcinoma. After radical radiotherapy, salvage surgery should be undertaken in the case of tumor remnants or recurrences.
