Correlation between c-erb-B2 overexpression with disease-free survival and rate of pelvic relapse in patients with advanced cervical cancer treated with chemo-radiotherapy

16004 Aims: To determine the impact of the c-erb-B2 overexpression receptor on pelvic relapse and on disease-free survival (DFS) in patients with advanced cervical cancer receiving concurrent chemo-radiotherapy. Methods: One hundred thirty six patients with advanced cervical cancer (stage: 12 IB2-IIA, 34 IIB, 71 IIIB, 19 IVA); histology: 86 epidermoid and 14 adenocarcinoma) were analyzed to detect c-erbB-2 level using an immunohistochemical method (Herceptest Dako). Cases c-erbB-2 (+3) were considered positive. All patients received pelvic radiotherapy, brachitherapy and concurrent chemotherapy with two schedules: 48 patients with tegafur (800 mg/day via oral) and 88 with tegafur (same doses) plus five cycles of weekly cisplatin 40 mg/m2/week iv. Results: Of the 136 biopsies, 32 (23.5%) were c- erbB-2 positive. The disease free survival to 3 and 5 years of the patients were 61% and 58% for c-erb-B2 negative and 36% and 36% for c-erb- B2 positive (p=0.02), respectively.We divided our patients in four group...
