CONTEXT In patients with brain metastases, it is unclear whether adding up-front whole-brain radiation therapy (WBRT) to stereotactic radiosurgery (SRS) has beneficial effects on mortality or neurologic function compared with SRS alone. OBJECTIVE To determine if WBRT combined with SRS results in improvements in survival, brain tumor control, functional(More)
PURPOSE We studied whether i.v. administration of a chemokine after local tumor site irradiation could prevent remaining, as well as distant, nonirradiated tumor cell growth by leukocyte recruitment. EXPERIMENTAL DESIGN Tumors were implanted s.c. in the right or both flanks. After local irradiation at the right flank, ECI301, a human macrophage(More)
UNLABELLED In the management of rectal cancer after the combined therapy of the radiation and surgical operation, the evaluation of the prognosis is important. Although fluoro- 18-deoxyglucose positron emission tomography (FDG-PET) is considered as a useful tool for evaluation of therapeutic effect of this cancer as well as the other cancers, however, there(More)
Tumor tissues and adjacent normal tissues in 12 colorectal cancers were examined for quantitative differences in: i) activity of DNA-dependent protein kinase (DNA-PK), which functions in DNA double-strand breads repair, and ii) protein and mRNA levels of Ku70, Ku80, DNA-PKcs and transcriptional factor Sp1. DNA-PK activity and protein/mRNA levels of Ku70,(More)
It has been well established that estrogen is involved in the pathophysiology of breast cancer. Estrogen receptor (ER) alpha appears to promote the proliferation of cancer tissues, while ERbeta can protect against the mitogenic effect of estrogen in breast tissue. The expression status of ERalpha and ERbeta may greatly influence on the development,(More)
BACKGROUND Stereotactic radiosurgery (SRS) is among the few therapeutic options for glioblastoma that recurs after standard radiation and chemotherapy, but its efficacy has been limited. METHODS Since November 2007, the authors have modified the clinical target volume by adding a 0.5- to 1-cm margin to the gadolinium-enhanced area (extended field SRS), in(More)
Central neurocytoma was first described by Hassoun et al. in 1982. The tumor is a rare benign tumor of the central nervous system, usually located in the lateral ventricles. Most reported cases are histologically and clinically benign. Several cases with recurrence have been described. Including the case presented here, only seven cases with craniospinal(More)
PURPOSE To determine how the omission of whole brain radiotherapy (WBRT) affects the neurocognitive function of patients with one to four brain metastases who have been treated with stereotactic radiosurgery (SRS). METHODS AND MATERIALS In a prospective randomized trial between WBRT+SRS and SRS alone for patients with one to four brain metastases, we(More)
PURPOSE To evaluate, in Japan Clinical Oncology Group study 0403, the safety and efficacy of stereotactic body radiation therapy (SBRT) in patients with T1N0M0 non-small cell lung cancer (NSCLC). METHODS AND MATERIALS Eligibility criteria included histologically or cytologically proven NSCLC, clinical T1N0M0. Prescribed dose was 48 Gy at the isocenter in(More)
PURPOSE To investigate the three-dimensional movement of internal fiducial markers placed near esophageal cancers using 320-multislice CT. METHODS AND MATERIALS This study examined 22 metal markers in the esophageal wall near the primary tumors of 12 patients treated with external-beam photon radiotherapy. Motion assessment was analyzed in 41 respiratory(More)
