Abstract
PURPOSE
This study reports the results of a single-institution experience with high-dose-rate brachytherapy (HDRBT) used as a boost in the treatment of esophageal cancer with external beam radiation therapy (ERT) with or without chemotherapy.
METHODS AND MATERIALS
Patients without evidence of metastatic disease were identified. HDRBT was given before ERT with a dose of 20 Gy in 5 fractions. Patients with a Karnofsky performance of more than 70 received treatment with 50 Gy in 25 fractions and concurrent 5-fluorouracil and cis-platinum during Weeks 1 and 5, whereas patients with a Karnofsky performance of less than 70 were treated with radiation therapy alone with 35 Gy in 14 fractions.
RESULTS
Fifty-three patients received HDRBT treatment with combined ERT and chemotherapy and 17 patients with ERT alone. The incidence of acute bone marrow toxicity was 55% Grade 2 and 15% Grade 3, and 85% of patients had Grade 2 esophagitis. With a median follow-up time of 26 months, the median survival was 21 months; the 2-year local recurrence was 25%, and the 5-year survival rate was 28%.
CONCLUSION
HDRBT is safe and beneficial for local control in the radical treatment of patients with esophageal cancer.
