Aims And Background:
Little is known about chemoradiotherapy in elderly patients with locally advanced esophageal cancer. We compared the efficacy and toxicity of chemoradiotherapy in elderly and non-elderly patients with locally advanced esophageal cancer and determined the variables affecting the treatment outcome in the elderly patients with locally advanced esophageal cancer who had received chemoradiotherapy.
Methods:
Fifty-seven elderly patients (age ≥ 65 years) and 30 non-elderly patients (age <65 years) were reviewed retrospectively.
Results:
The median age of the elderly group was 69 years and in the non-elderly group, 56.5 years. Although treatment compliance appeared to be poor, the response rate and median survival were similar in both the groups (elderly versus non-elderly; 84.4% vs 87.5%, and 11.2 months vs 11.3 months) and so were G3/4 hematologic and non-hematologic toxicities. The treatment-related mortality of the elderly patients appeared to be higher than that of the non-elderly group (7.0% vs 3.3%), but did not reach statistical significance. In prognostic factor analysis, a major response to chemoradiotherapy was a good prognostic indicator in the elderly group (response versus non-response; median overall survival times of 19.5 vs 5.4 months, respectively, P <0.001).
Conclusions:
The study suggests that chemoradiotherapy for locally advanced esophageal cancer in elderly patients, even though treatment compliance appears to be poor, is as safe and effective as in non-elderly patients and that the response to chemoradiotherapy is related to prognosis in elderly patients.
