Purpose: This study was designed to retrospectively analyze the safety and efficacy of chemoradiation therapy with nedaplatin and 5-fluorouracil in elderly patients with esophageal squamous cell carcinoma. Methods and materials: Eligible patients were aged 76 years or older, had a histopathologic diagnosis of esophageal squamous cell carcinoma, and were treated at the Kitasato University Hospital between January 2010 and March 2016. Chemotherapy consisted of nedaplatin in an intravenous dose of 90 mg/m2 on day 1 and 5-fluorouracil in an intravenous dose of 800 mg/m2 on days 1 to 5, repeated every 4 weeks for 2 cycles. Radiation therapy consisted of 50.4 Gy in 28 fractions for thoracic tumors and 61.2 Gy for cervical tumors. Results: Twenty-five patients were studied. Patient characteristics were as follows: median age 79 years (range, 76-85 years), clinical stage I/II/III/IV (7/8/8/2, respectively), and surgically resectable/unresectable (17/8, respectively). The completion rates of radiation therapy and chemoradiation therapy were 100% and 84%, respectively. Grade ≥3 acute toxicities included neutropenia (76%), leukopenia (72%), thrombocytopenia (32%), anemia (28%), anorexia (32%), oral mucositis (20%), febrile neutropenia (12%), and esophagitis (8%). Grade ≥3 late toxicities included esophageal stenosis (12%) and pleural effusion (4%). The complete response rate was 64%. In the median follow-up period of 18.9 months, the 1-year overall survival rate was 68%. Conclusions: Definitive chemoradiation therapy with nedaplatin and 5-fluorouracil may be a feasible treatment option for elderly patients with esophageal squamous cell carcinoma.
