Objective. We recently published results of a phase III trial demonstrating superior outcomes in patients with locally advanced cervical cancer (LACC) when concurrent cisplatin chemoradiotherapy is supplemented with concurrent gemcitabine and adjuvant gemcitabine/cisplatin. We present prognostic and predictive factors identified in that study, along with analyses of the effect of disease stage and post-study therapy. Patients and methods. In that trial, 515 patients with stage IIB-IVA LACC were administered concurrent cisplatin chemoradiotherapy with or without gemcitabine and adjuvant gemcitabine/cisplatin. Cox models were used to identify prognostic and predictive factors. Survival was estimated using the Kaplan-Meier method. Results. Advanced (stage III-IVA) disease, squamous histology, low hemoglobin, the presence of >= 1 enlarged para-aortic lymph nodes, and large tumor size, were associated with poorer prognosis, regardless of treatment assigned. Tumor size and histology were predictive of treatment efficacy. Chemoradiotherapy supplemented with gemcitabine produced relatively greater benefit in patients with stage III/IVA disease. Post-study therapy did not appear to affect the overall survival outcome. Conclusion. Prognostic factors identified in this study are consistent with other reports. The finding of relatively greater benefit in advanced-stage patients makes for an important factor in consideration of treatment for these patients and the design of future studies.
