To analyze outcomes and toxicities of stereotactic body radiotherapy with helical tomotherapy (HT-SBRT) for inoperable lung tumors, the medical records of 30 patients with 31 lung tumors treated with HT-SBRT were reviewed. The 3-year local control, cause-specific survival and overall survival rates (LC, CCS and OS, respectively) were analyzed using the(More)
We describe a mediastinal pancreatic pseudocyst treated with a catheter drainage placed under computed tomographic guidance using a newly applied approach. A needle was angled cephalad with the computed tomographic gantry tilt technique, and was inserted into the lowest portion of the cavity through the liver and through the diaphragm. The needle pathway(More)
AIM To evaluate an appropriate planning target volume (PTV) margin in for one to three vertebral metastases using megavolt computed tomography (MVCT) images during the course of image-guided and stereotactic intensity-modulated radiotherapy (IGRT-IMRT) by use of helical tomotherapy. PATIENTS AND METHODS A total of 25 lesions in 24 patients with vertebral(More)
A thirty-four-year-old man was admitted to our hospital because of the disturbed visual acuity and pain on the eye movement of the right eye. He had prominent right eye and CT-scan and MRI of the brain disclosed a tumor which could be obviously distinguished from the extraocular muscles, optic nerve and the bulb of eye in the retrobulbar region. On(More)
AIM This prospective multicenter study aimed to evaluate the efficacy and adverse events of hepatic arterial infusion chemotherapy (HAIC) using percutaneous catheter placement techniques for liver metastases from colorectal cancer (CRC). METHODS We administered 5-fluorouracil at 1000 mg/m2 over 5 h via hepatic arterial infusion on a weekly schedule. The(More)
INTRODUCTION Radiotherapy is a standard treatment for prostate cancer, and image-guided radiotherapy is increasingly being used to aid precision of dose delivery to targeted tissues. However, precision during radiotherapy cannot be maintained when unexpected intrafraction organ motion occurs. CASE PRESENTATION We report our experience of internal organ(More)
The present study aimed to describe the clinical results of re-irradiation (Re-RT) for spine or pelvic bone metastasis at the same initial irradiated area. Between April 2010 and March 2014, cases involving 98 patients with spine or pelvic bone metastasis who had undergone Re-RT at five institutions were reviewed. The clinical outcomes following Re-RT were(More)
AIM To analyze an intrafractional organ motion for patients with prostate cancer using soft tissue matching by megavolt computed tomography (MVCT) images during the course of image-guided intensity-modulated radiotherapy (IGRT-IMRT) using helical tomotherapy. PATIENTS AND METHODS Data from a total of 10 patients with prostate cancer who received IGRT-IMRT(More)
AIM To investigate the frequency and characteristics of interfractional rectal displacement in patients with prostate cancer treated with image-guided intensity-modulated radiation therapy (IG-IMRT) using helical tomotherapy. PATIENTS AND METHODS Data for a total of 256 patients were analyzed. Megavoltage computed tomography (MVCT) images were acquired(More)
BACKGROUND Glioblastoma has a very poor prognosis even after incorporation into therapy of the newly-developed drug, temozolomide. CASE REPORT We present a case of 62-year-old woman with glioblastoma multiforme treated with tomotherapy intensity-modulated radiation therapy using simultaneous integrated boost technique (SIB-IMRT) along with a daily oral(More)
