This study aimed to evaluate the efficacy and safety of reirradiation with intensity-modulated radiation therapy (IMRT) for spinal metastases. We retrospectively analyzed 23 patients with spinal metastases who underwent IMRT reirradiation between December 2006 and July 2013. We evaluated the spinal radiation doses during the first and second radiation(More)
OBJECTIVE Pancreatic cancer is a difficult to treat disease with a persistently high mortality rate. We evaluated dose distribution simulation with respiratory-gated carbon-ion pencil beam scanning (C-PBS) with a simultaneous integrated boost (SIB) to increase tumour dose, sparing organs at risk (OARs). METHODS Using four-dimensional CT data of 12(More)
BACKGROUND The safety and effectiveness of carbon-ion radiotherapy (CIRT) for isolated para-aortic lymph node (PALN) metastasis was evaluated retrospectively. METHODS CIRT for isolated PALN metastasis from CRC was performed in 34 cases from June 2006 to August 2015 in our institute. A median dose of 52.8 Gy(RBE) (range, 48-52.8 Gy(RBE)) was delivered with(More)
