OBJECTIVE: The aim of the study was to investigate the prognostic factors for survival and treatment-related toxicities in older (≥65 years) cervical cancer patients treated with definitive chemoradiotherapy. In addition, we sought to compare the outcomes between the older elderly (≥75 years) and their younger old counterparts (age, 65-74 years).
MATERIALS AND METHODS: We retrospectively reviewed medical records from 269 biopsy-proven nonmetastatic cervical cancer patients treated with external radiotherapy and intracavitary brachytherapy at the departments of radiation oncology in 2 different universities. The prognostic factors for survival, local control, and distant metastasis (DM) were analyzed.
RESULTS: The median follow-up time was 38.8 months (range, 1.5-175.5 months) for the entire cohort and 70.0 months (range, 6.1-175.7 months) for survivors. The 2- and 5-year overall survival (OS), disease-free survival (DFS), and cause-specific survival rates were 66% and 42%, 63% and 39%, and 72% and 55%, respectively. Patients 75 years or older showed significantly worse OS compared with patients aged 65 to 74 years but showed no significant difference in DFS. The 2- and 5-year local control rates were 86% and 71%, respectively. The incidences of DMs at 2 and 5 years were 22% and 30%, respectively. In multivariate analysis, vaginal infiltration and lymph node metastasis were predictive of OS, DFS, local recurrence, and DM. Concomitant chemotherapy was predictive of OS, DFS, and local recurrence, and larger tumor (>4 cm) was a significant prognostic factor for local recurrence. None of the patients had toxicity that necessitated the discontinuation of radiotherapy. All patients were evaluable for acute toxicity, and no grade higher than 3 adverse events occurred during external beam radiation therapy or brachytherapy.
CONCLUSIONS: Although age limited the delivery of aggressive treatment, concurrent chemoradiotherapy in elderly patients associated with improved outcomes similar as in younger counterparts without increasing serious acute and late toxicities.
