%X Objective: The objective was to determine the impact of the coexpression of epidermal growth factor receptor (EGFR) and tumor marker c-erbB-2 on disease-free survival (DFS) and pelvic relapse-free survival (PRFS) in patients with locally advanced cervical cancer (LACC) receiving concurrent chemoradiotherapy.Methods: The expression of EGFR and c-erbB-2 was assessed by immunohistochemistry, which was centralized and blinded to outcome. Univariate and multivariate analyses were used to evaluate the impact of EGFR and c-erbB-2 on DFS and PRFS.Results: 170 patients with LACC were included and received concurrent chemoradiotherapy. 25 (15%) biopsies were considered EGFR and c-erbB-2 positive; 100 (59%) were either EGFR or c-erbB-2 positive, and 45 (26%) were EGFR and c-erbB-2 negative. The 3- and 5-year DFS was 39% each for EGFR- and c-erbB-2-positive patients, 54 and 49%, respectively, for EGFR- or c-erbB-2-positive patients, and 76 and 72%, respectively, for EGFR- and c-erbB-2-negative patients (p = 0.006). EGFR- and c-erbB-2-positive tumors were significantly associated with a decrease in PRFS (hazard ratio, HR, 3.99; 95% confidence interval, CI, 1.44-11.05, p = 0.007), and DFS (HR 2.9; 95% CI, 1.26-6.66, p = 0.01).Conclusion: Patients with LACC coexpressing EGFR and c-erbB-2, and treated with concurrent chemoradiotherapy, had a worse clinical prognosis with shorter DFS and PRFS.
