چکیده

BACKGROUND AND OBJECTIVE In the last decade, the number of publications that report on the use of external beam radiotherapy and high-dose-rate brachytherapy (HDR-BRT) in the treatment of recurrent head and neck cancer has increased, but no studies compare external beam radiotherapy and HDR-BRT. The aim of this study was to evaluate and to compare the efficacy and toxicity of the three-dimensional conformal radiotherapy (3D-CRT) and HDR-BRT in the treatment of recurrent head and neck cancer. MATERIAL AND METHODS A total of 64 patients with head and neck cancer recurrence were randomly assigned at a 1:1 ratio to receive either 3D-CRT (50Gy/25 fractions) in the control group or HDR-BRT (30Gy/12 fraction) in the experimental group. RESULTS The overall survival rate of patients treated with HDR-BRT at 1 and 2-years was 74% and 67%, respectively, compare to 3D-CRT group - 51% and 32%, respectively (P=0.002). Local control at 1- and 2-years in patients who received HDR-BRT was 77% and 63% compare with 47% and 25%, respectively, for the patients who received the 3D-CRT (P<0.001). Most patients developed mild to moderate acute mucositis and dermatitis. In the 3D-CRT group, severe late toxicity was determined in 11 patients (35.5%), and in the HDR-BRT group, in 1 patient (3.1%) (P=0.001). There was no grade 5 toxicity. CONCLUSIONS Following our results, we concluded that HDR-BRT is a more effective and safer treatment approach for head and neck cancer recurrences than 3D-CRT.
