Radiotherapy of Early Stage Glottic Cancer / 대한치료방사선과학회지

ABSTRACT

PURPOSE: To evaluate the role of curative radiotherapy and salvage surgery in patients with T1,T2 glottic cancer. MATERIALS AND METHOD: Between June 1989 and December 1994, 23 patients with early glottic cancer, 18 with T1N0M0 and 5 with T2N0M0, were treated with radiotherapy at Gyeongsang National University Hospital. All patients were male. Median follow-up period was 46 months, and 100% were observed for at least 3 years. RESULTS: Actuarial survival rates at 5 years were 84.3% for 23 patients. The 5-year actuarial survival rates were 94.4% for T1 and 53.3% for T2 (P=0.05). The 5-year local control rates was 70.0% for T1 and 60.0% for T2 (P=0.44). Of 8 patients with treatment failure, 6 patients (75.0%) were salvaged with surgery. After surgical salvage, the 5-year local control rates were 87.2% for T1 and 80.0% for T2(p=0.55). CONCLUSION: In early stage (Stage I and II) glottic cancer, curative radiotherapy can be a treatment of choice and surgery reserved for salvage of radiotherapy failure.
