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.
Since immortalization by HPV E6/E7 is an important early event in cervical carcinogenesis, the EGFR is a potential target for chemoprevention or therapy in women who have a high risk for cervical cancer.
The aim of this study was to systematically analyze the molecular mechanism leading to epidermal growth factor receptor overexpression in cervical cancer.
Membranous expression of ectodomain isoforms of the epidermal growth factor receptor predicts outcome after chemoradiotherapy of lymph node-negative cervical cancer.
For cervical cancer, our results suggested that potential drugs are likely to involve the EGFR pathway; and with the breast cancer dataset, we identified candidates that are involved in prostaglandin inhibition.
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.
For the purpose of identifying prognostic factors for pretreated uterine cancer, DNA ploidy, proliferative index (P.I.) and epidermal growth factor receptor (EGFR) expression were analyzed in a large prospective series of 76 cervical cancer and 64 endometrial cancer patients observed for 5 years or more (median 76 months).
