PURPOSE To investigate pelvic insufficiency fractures (IF) after definitive pelvic radiation therapy for early-stage uterine cervical cancer, by analyzing subjects of a prospective, multi-institutional study. MATERIALS AND METHODS Between September 2004 and July 2007, 59 eligible patients were analyzed. The median age was 73 years (range, 37-84 years).(More)
The purpose of this study was to examine the relation between cancer cellularity and the apparent diffusion coefficient (ADC) value using diffusion-weighted magnetic resonance imaging in breast cancer. The subjects were 27 women who had undergone operation for breast cancer. There were 27 breast cancer lesions, 24 of which were invasive ductal carcinoma(More)
The purpose of this study is to examine the association between sudden cardiac death (SCD) and heart rate variability (HRV) in subjects with and without type 2 diabetes and to determine whether low HRV can predict SCD in type 2 diabetes. Subjects were 8917 consecutively examined persons (3089 diabetic, and 5828 nondiabetic subjects) aged 35-69 years who(More)
PURPOSE Most patients who had any recurrent sites of cancer have been considered to be in their last stage of life. However, recent advances of clinical research reveal some patients achieve long-term survival even in recurrence. Furthermore, for patients who had only one recurrent region, radiation therapy could play an important role. As for uterine(More)
BACKGROUND The relationship between a positive resection margin and the risk of ipsilateral breast tumor recurrence (IBTR) is controversial. To evaluate the radiation dose and other factors influencing the ipsilateral breast tumor control (IBTC) in patients with positive or close resection margins after breast conserving surgery (BCS), the Japanese(More)
OBJECTIVE The health-related quality of life (HRQOL) after treatment of prostate cancer is examined using a new HRQOL tool. HRQOL, based on the expanded prostate cancer index composite (EPIC) and SF-8 questionnaires, was prospectively compared after either a radical retropubic prostatectomy (RRP) or a permanent prostate brachytherapy (PPB) at a single(More)
OBJECTIVE The health-related quality of life (HRQOL) after a radical retropubic prostatectomy (RRP) or a permanent prostate brachytherapy (PPB) was prospectively compared at a single institute. METHODS Between 2003 and 2005, 122 patients were treated by RRP and 82 patients were treated by PPB. A QOL survey was completed at baseline, and 1, 3, 6 and 12(More)
We retrospectively investigated the impact on survival of early tumor reduction during definitive radiotherapy for inoperable stage III non-small cell lung cancer (NSCLC) patients, according to their histological subtypes. Between November 2006 and December 2012, 152 consecutive patients with inoperable stage III NSCLC who underwent definitive radiotherapy(More)
Breast cancer-detecting ability of diffusion-weighted magnetic resonance imaging (DW-MRI) was investigated by comparing the breast cancer detection rates of DW-MRI and mammography (MMG). The subjects were 48 women who had breast cancer (53 cancer lesions) who underwent DW-MRI before surgery. Altogether, 41 lesions were invasive ductal carcinoma (IDC), 7(More)
OBJECTIVE A previous paper reported favorable results of intra-arterial chemotherapy in combination with radiotherapy for muscle-invasive bladder cancer. The current study will update those results. METHODS Between January 1992 and December 2006, 94 patients with confirmed muscle invasion were treated with intra-arterial chemotherapy and concurrent(More)
