Background
We aimed to compare the safety of radiotherapy with concurrent docetaxel (DOC-RT) for esophageal cancer (EC) in elderly patients who were divided into a creatinine clearance (Ccr) < 60 mL/min (Ccr-L) group and a Ccr ≥ 60 mL/min (Ccr-H) group.
Methods
Eligible patients included those aged ≥ 76 years who were diagnosed with esophageal squamous cell carcinoma. The patients received radiotherapy (60 Gy in 30 fractions) and concurrent docetaxel (10 mg/m2 weekly for six cycles), after which toxicity and treatment completion rates were retrospectively evaluated.
Results
The 73 elderly EC patients receiving DOC-RT were divided into two groups for evaluation: the Ccr-L group (49 patients) and the Ccr-H group (24 patients). The median survival time for patients in the Ccr-L and Ccr-H groups was 21 and 20 months, respectively (p = 0.2). The incidence of grade 1 acute kidney injury was 8% vs. 8% (p = 1) in the Ccr-L and Ccr-H groups, respectively. No other hematological or nonhematological toxicities differed between patients in the two groups. No grade 4 or 5 toxicities were observed in the two groups. No significant difference was observed in the treatment completion rates (88% vs. 92%, p = 1) between patients in the Ccr-L and Ccr-H groups.
Conclusions
Regardless of baseline renal function, DOC-RT is a safe regimen for elderly patients with EC.
