Background/aims: The optimal regimen of radiotherapy (RT) for bleeding from gastric cancer (GC) has not yet been established. The aim of this study was to evaluate the usefulness of low-dose, short-course palliative RT (LSP-RT) for bleeding from GC.
Material and methods: We reviewed the clinical data of 18 patients (26 courses) who received palliative RT for bleeding from GC between 2004 and 2014. The radiation dose was 6 Gy in three fractions. The total courses of RT for each patient were 1-4 (median, 1).
Results: The treatment success rate of the first and the additional RT at two weeks after RT was 55% and 75%, respectively. Regarding first RT, there was a statistically significant increase in the mean hemoglobin level for one month (p = 0.009) and a significant decrease in the mean number of transfused red blood cell units for one month (p = 0.012). Toxicities were observed in two patients: one patient who received chemotherapy developed grade 3 afebrile leukocytopenia and another who had a malignant stricture suffered from a gastric obstruction. The performance status was improved in 3 of the 12 evaluable patients (25%) and dietary intake became possible one month after RT in three of the four patients who had not been able to eat before RT.
Conclusion: LSP-RT is expected to be not only an effective and safe treatment option for bleeding from GC, but also repeatable in cases of rebleeding. Furthermore, this treatment modality may be able to improve the patient's quality of life.
