Sažetak
Abstract Purpose To evaluate the prognostic significance of excision repair cross-complementation group 1 (ERCC1)expression in head and neck carcinoma patients treated with definitive radiotherapy (DR) or adjuvant radiotherapy (AR.Methods ERCC1 expression was assessed by immunohistochemical staining. A total of 48 patients were assessed.Results High ERCC1 expression was found in 23 patients (48 %). More ERCC1-positive tumours were detected in patients treated with DR than in patients treated with AR (73 vs. 36 %, respectively, p = 0.03). ERCC1 expression had no impact on overall survival neither in the whole cohort of patients (p = 0.16) nor in each particular treatment group (AR p = 0.98 ; DR p = 0.21). Conclusions ERCC1 expression had no predictive value in head and neck carcinoma patients treated with DR or AR. There might be difference in ERCC1 positivity that comes out of whether the assessment is done on biopsy or surgical specimens.
