The exact measurement of femoral head cover is essential for an assessment of reduction of congenital dislocation of the hip. We have compared standard anteroposterior radiographs with computerised tomograms and thereby classified the shape of the acetabular roof into four types. We found that the CE angle of Wiberg is a more reliable measure of head cover(More)
BACKGROUND AND PURPOSE Hyperfractionated accelerated radiotherapy without a split (AF) has been performed to improve the local control probability of early glottic carcinomas since 1990 in the authors' institution. Here, they report their experience treating early glottic cancer patients with AF in a single institution who have a long follow-up period. (More)
The DNA double-strand breaks (DSBs) repair pathway has been implicated in maintaining genomic integrity via suppression of chromosomal rearrangements. DNA-dependent protein kinase (DNA-PK) has an important role with DNA DSBs repair. In this study, 93 of untreated cancer patients and 41 of cancer-free healthy volunteers were enrolled. Peripheral blood was(More)
Hip arthrography was performed in 19 patients in the initial stage of Perthes' disease. Sphericity and subluxation were measured and it was found that subluxation was independent of the femoral head deformity. We therefore tried to identify the cause of early subluxation: in seven patients a swollen ligamentum teres was thought to be responsible, and was(More)
In patients undergoing radiotherapy for localized prostate cancer, dose-volume histograms and clinical variables were examined to search for correlations between radiation treatment planning parameters and late rectal bleeding. We analyzed 129 patients with localized prostate cancer who were managed from 2002 to 2010 at our institution. They were treated(More)
We report our experiences of four cases with meningeal hemangiopericytoma treated with surgery and postoperative radiotherapy and survey the literature to elucidate the efficacy of radiotherapy. Patients were treated with surgical resection and 46-52 Gy postoperative radiotherapy. Three patients had local control for 30, 54 and 138 months, respectively and(More)
BACKGROUND Non-Hodgkin lymphoma (NHL) represents a heterogeneous group of tumors that vary with regard to their biologic aggressiveness and clinical course. In in vitro studies, matrix metalloproteinase 9 (MMP9) was reportedly expressed by human NHL cells and elevated levels of MMP9 have been observed in a subset of patients with high-grade NHL. METHODS(More)
1 DNA-PK/Gene expression/Hypoxia/Reoxygenation. In order to elucidate the mechanism of concerted expression of various proteins related to DNA-PK activity, we examined the relationship of the expression of these proteins with that of a transcription factor Sp1. We also explored whether the expression of genes related to DNA-PK activity and Sp1 changed after(More)
DNA-dependent protein kinase (DNA-PK) has an important role in DNA double-strand break repair. We previously demonstrated the association of DNA-PK activity in peripheral blood lymphocytes (PBL) with incidence of chromosomal aberrations and risk of cancer. In this study, we examined the expression of Ku70 and Ku86 in breast cancer tissue and normal breast(More)
The results of definitive radiotherapy to elucidate the optimal doses of external irradiation (ERT) and low-dose-rate intraluminal brachytherapy (ILBT) were analyzed. Between 1979 and 1998, 100 patients with esophageal cancer were treated with ERT and ILBT. ERT was given at a dose of 40-65 Gy/25-32 fractions and ILBT at 10-24.3 Gy/2-3 fractions. The 5-year(More)
