Is age a prognostic biomarker for survival among women with locally advanced cervical cancer treated with chemoradiation? An NRG Oncology/Gynecologic Oncology Group ancillary data analysis
Abstract
Objective: To determine the effect of age on completion of and toxicities following treatment of local regionally advanced cervical cancer (LACC) on Gynecologic Oncology Group (GOG) Phase I-III trials.
Methods: An ancillary data analysis of GOG protocols 113, 120, 165, 219 data was performed. Wilcoxon, Pearson, and Kruskal-Wallis tests were used for univariate and multivariate analysis. Log rank tests were used to compare survival lengths.
Results: One-thousand-three-hundred-nineteen women were included; 60.7% were Caucasian, 15% were age 60-70years and an additional 5% were >70; 87% had squamous histology, 55% had stage IIB disease and 34% had IIIB disease. Performance status declined with age (p=0.006). Histology and tumor stage did not significantly differ. Number of cycles of chemotherapy received, radiation treatment time, nor dose modifications varied with age. Notably, radiation protocol deviations and failure to complete brachytherapy (BT) did increase with age (p=0.022 and p<0.001 respectively). Only all grade lymphatic (p=0.006) and grade≥3 cardiovascular toxicities (p=0.019) were found to vary with age. A 2% increase in the risk of death for every year increase >50 for all-cause mortality (HR 1.02; 95% CI, 1.01-1.04) was found, but no association between age and disease specific mortality was found.
Conclusion: This represents a large analysis of patients treated for LACC with chemo/radiation, approximately 20% of whom were >60years of age. Older patients, had higher rates of incomplete brachytherapy which is not explained by collected toxicity data. Age did not adversely impact completion of chemotherapy and radiation or toxicities.
