Abstract: Although there have been studies reporting the efficacy of palliative radiation in treating liver tumors, there are very few reports in Japan. Therefore, this study aimed to evaluate the effect of palliative radiation on pain in patients with liver tumors. Between December 2014 and November 2016, 15 patients received palliative radiotherapy of 8 Gy in a single fraction for primary or metastatic liver tumors. Among them, 12 patients were assessed for pain before and after the radiation therapy using the Numeric Rating Scale (NRS). A decrease in the NRS score post radiation therapy was reported in all cases. No grade 3 or higher acute phase adverse events were observed. In conclusion, palliative irradiation managing pain due to liver tumors is possibly effective in relieving pain and well tolerated.
