Popis: | Purpose Clinical evidence regarding optimal radiation dose for palliation of dysphagia from esophageal cancer is generally lacking. In an effort to investigate optimal radiation dose, we assessed 2 different radiation schedules for palliation of dysphagia. Methods and Materials We performed a multicenter, retrospective study comparing low-dose radiation therapy (LR: 5 x 4 Gy external beam radiation therapy [EBRT]) with high-dose radiation therapy (HR: 10 x 3 Gy EBRT and 12-Gy single-dose intraluminal brachytherapy) for palliation of dysphagia in patients with inoperable or metastasized esophageal cancer. Primary outcome was improvement of dysphagia at 6 weeks after start of radiation therapy. Additional outcomes were persistent and recurrent dysphagia during patients' remaining life, severe adverse events, and survival. Results In total, 292 patients (LR, n=117; HR, n=175) were included in this study. After matching, 144 patients (72 in each group) were compared. Improvement of dysphagia at 6 weeks was achieved in 50% of patients after LR and in 66% after HR (P = .071). Persistent or recurrent dysphagia occurred in 64% of patients after LR and in 42% after HR (P = .012). No difference in the rate of severe adverse events was found (P = .889). Median survival was 88 days (95% confidence interval, 64-112) after LR and 177 days (95% confidence interval, 131-223) after HR (P Conclusions This study shows that both LR and HR were well tolerated and effective in short-term relief of dysphagia in patients with inoperable or metastasized esophageal cancer. HR was associated with better long-term relief of dysphagia compared with LR. Our findings suggest that HR could be considered for patients with a longer life expectancy, but prospective studies are required. |
