Hyperfractionated radiotherapy with concurrent chemotherapy for advanced esophageal cancer

: The clinical efficacy and safety of hyperfractionated radiotherapy with concurrent chemotherapy were studied retrospectively in patients with primary advanced esophageal cancer. The subjects were 31 patients who were treated with hyperfractionated radiotherapy and concurrent chemotherapy in our institution between 1990 and 2001. The chemoradiotherapy consisted of cisplatin 70-80 mg/m2 on day one, and continuous infusion of 5-fluorouracil 700-800 mg/m2/24 hours on days 1 to 3, with concurrent hyperfractionated radiotherapy (57.6-72 Gy). Complete remission (CR) was observed in 17 cases, and partial response in 13 cases (response rate: 96. 7%). Three-year survival rate and 5-year survival rate were 35.5% and 26.3%, respectively. Grade 3/4 hematological toxicities included leukocytes in 7 patients (22.6%), hemoglobin in 6 patients (19.4%), and platelets in 4 patients (12.9%). Grade 3 dysphagia-esophageal related to radiation was observed in 3 patients (9.7%). Late toxicities occurred with the following incidences: hypothyroidism in 2 patients, benign esophageal strictures in 2 patients, pericardial effusion in 8 patients, and pleural effusion in 8 patients. The results suggest that combined chemotherapy and hyperfractionated radiotherapy is an effective and well-tolerated regimen.
