| Abstract: The aim of the present retrospective study was to evaluate the prognostic significance of epidermal growth factor receptor (EGFR) expression in patients treated with radiotherapy or concomitant chemoradiotherapy for squamous cell anal cancer (SCAC) Patients and methods: A total of 17 patients with SCAC (clinical stages I-III) were studies. All patients were treated with radiotherapy (total dose range 40 – 68 Gy), 13 patients received concomitant chemotherapy (7 patients mitomycin/5-fluorouracil, 5 patients cisplatine/5-fluorouracil, 1 patient cisplatine weekly). EGFR expression in the pretreatment biopsieswas assessed with imunohistochemistry. Patients with EGFR expression had significantly shorter progression free survival (PFS) (p=0.0109; HR 9.38, 95% CI 1.75 – 50.35) and overall survival (OS) (p=0.0351; HR 7.11, 95% CI 1.4 – 36.13) than patients without expression EGFR. The 4-year PFS in patients with increased EGFR expression was only 28.57% (95% CI 17.07 – 62.04%) compared to 87.5% (95% CI 64.58 - 100%) in patients without EGFR expression. The 4-year OS in patients with increased EGFR expression was only 50.0% (95% CI 15.35 – 84.65%) compared to 87.5% (95% CI 64.58 – 100.0%) in patients without EGFR expression. Patients with expression EGFR had significantly shorter PFS and OS compared with patients without EGFR expression. |
