Phase II study of cisplatin plus cetuximab in advanced, recurrent, and previously treated cancers of the cervix and evaluation of epidermal growth factor receptor immunohistochemical expression: a Gynecologic Oncology Group study.
In 112 consecutive patients with advanced cancer of the cervix (11 stage IB2-IIA, 25 IIB, 63 IIIB, 13 IVA) treated with chemoradiotherapy between December 1994 and September 2004, the expression of EGFR using histoimmunochemistry was measured and used in univariate and multivariate analysis, along with variables such as age, International Federation of Gynecology and Obstetrics Staging System for Epithelial Ovarian Cancer (FIGO) stage, histology, Eastern Cooperative Oncology Group (ECOG), tumor size, and ganglia involvement diagnosed with computerized axial tomography, treatment with cisplatin to evaluate its impact on DFS and pelvic relapse.
EGFR messenger RNA (mRNA) expression was correlated with EGFR densities on the cell surface of 5 different cervical cancer cell lines and with receptor function, measured by internalization of (64)Cu-DOTA-cetuximab.
