ABSTRACT
PURPOSE:
To report the results of curative treatment for patients with tonsil cancer by retrospective analysis. MATERIALS ANDMETHODS:
From Jan. 1995 till Dec. 2000, 27 patients with squamous cell carcinoma of the tonsil received curative treatment at Samsung Medical Center. Therapeutic decision was made through multidisciplinary conference, and curative radiation therapy was favored when, (1) the patient's condition was not fit for general anesthesia and surgery, (2) the patient refused surgery, (3) complete resection was presumed impossible, or (4) too severe disability was expected after surgery. Surgery was the main local modality in 17 patients (S+/-RT group), and radiation therapy in 10 (RT+/-CT group). The median follow-up period was 41 months.RESULTS:
AJCC stages were I/II in four, III in two, and Iv in 21 patients. The 5-year disease-free survival rate was 73.3% in all patients, 70.6% in the S+/-RT group, and 77.8% in the RT+/-CT group. Treatment failure occurred in seven patients, all with stage III/IV, and all the failures occurred within 24 months of the start of treatment. Five patients among the S CT group developed treatment failures; 2 local, 2 regional, and 1 distant (crude rate=29.4%). Two patients among the RT+/-CT group developed failures; 1 synchronous local and regional, and 1 distant (crude rate=20.0%). The 5-year overall survival rate was 77.0% in all patients, 80.9% in the S+/-RT group, and 70.0% in the RT+/-CT group.CONCLUSION:
We could achieve favorable results that were comparable to previously reported data with respect to both the rates of local control and of survival by applying S+/-RT and RT+/-CT. RT+/-CT is judged to be an alternative option that can avoid the functional disability after surgical resection.
