Brain metastases from gynecological cancers were retrospectively investigated in 18 patients who were treated between 1985 and 2006. Six patients received surgical resection followed by radiotherapy, and 12 patients received only radiotherapy. The median survival for all patients was 4.1 months (range 0.7-48.2 months), and the actuarial survival rates were(More)
BACKGROUND Nobody knows whether cognitive dysfunction affects survival. Furthermore, it is unknown whether the dysfunction is caused by the tumor itself or by its treatment. METHODS Patients with 20 gliomas (LGG, 7; MG, 13 [AG, 4; GM, 9]) in the right brain (nondominant) and 11 gliomas (LGG, 1; MG, 10 [AG, 6; GM, 4]) in the left brain (dominant) were(More)
BACKGROUND To analyze retrospectively the results of treatments for patients with brain metastases from breast cancer. MATERIALS AND METHODS The records of 65 breast cancer patients with brain metastases who were treated between 1985 and 2005 were reviewed. For brain metastases, 11 patients (17%) were treated with surgical resection followed by(More)
SUMMARY This paper describes recent developments of photonic crystal fibers (PCFs), which can realize ultra wide-band transmission or large A eff , as well as photonic crystal multi-core fibers (PC-MCFs), which have large potentials as future high-capacity transmission lines using Space Division Multiplexing.
INTRODUCTION Dural arteriovenous fistulae (DAVF) occasionally lead to cognitive disorders whose reversibility after DAVF treatment remains unclear. We studied changes on pre- and post-treatment magnetic resonance imaging (MRI) and single photon emission computed tomography (SPECT) scans in ten patients with cognitive disorder due to DAVF. METHODS We(More)
