This study aims to clarify the validity of the brief screening measure of depression in Japan. It was the single-item interview "Are you depressed?" that provided a reliable and remarkable accurate screen in North America. The study was conducted on 282 participants receiving radiotherapy for cancer. The criterion diagnosis were given by the Structured(More)
To evaluate the dosimetric impact of respiratory breast motion and daily setup error on whole breast irradiation (WBI) using three irradiation techniques; conventional wedge (CW), field-in-field (FIF) and irregular surface compensator (ISC). WBI was planned for 16 breast cancer patients. The dose indices for evaluated clinical target volume (CTV(evl)),(More)
Radiation therapy (RT) for metastatic pelvic lymph nodes (PLNs) is not well established in cervical cancer. In this study the correlation between size of lymph nodes and control doses of RT was analyzed. Between January 2002 and December 2007, 245 patients with squamous cell carcinoma of the cervix treated with a combination of external beam irradiation(More)
This study was carried out to evaluate the influence of fraction size 2.25 Gy on local control of T1 and T2 laryngeal and hypopharyngeal cancers. Between August 2002 and December 2010, 80 patients with T1 and T2 laryngeal or hypopharyngeal cancers were treated with definitive radiotherapy with a fraction size of 2.25 Gy. Primary sites were the larynx in 69(More)
Delirium is a common psychiatric illness among medically compromised patients. There is an increasing opportunity to use atypical antipsychotics to treat delirium. The effects of these drugs on delirium, however, the most appropriate way to use them, and the associated adverse effects remain unclear. To clarify these points, a prospective open trial on(More)
The prognostic value of rectal invasion is still unclear in stage IVA cervical cancer. The objective of this study is to evaluate patient outcome and prognostic factors in stage IVA cervical cancer treated with radiation therapy. A retrospective review of the medical records of patients treated with definitive photon radiation therapy for pathologically(More)
The aim of this study was to evaluate the toxicity and efficacy of radiotherapy concurrent with weekly cisplatin for T3-4 and N0-1 nasopharyngeal cancer. Between 2005 and 2010, 70 patients with nasopharyngeal cancer (T3-4 N0-1 M0, World Health Organization Type 2-3) from Vietnam, Indonesia, Malaysia and Thailand were registered. Patients were treated with(More)
Although a relatively small proportion of all breast cancer (BC), triple negative (TN) BC is responsible for a relatively large proportion of BC deaths because of its worse clinical outcome. To investigate whether a carbon ion beam alone or in combination with cisplatin (CDDP) has a beneficial effect compared to X-rays, we target triple negative (TN) breast(More)
This multicenter prospective study ( Japanese Radiation Oncology Study Group: JROSG 05-5) aimed to evaluate the effectiveness of postoperative radiotherapy (PORT) in patients with ductal carcinoma in situ (DCIS) with an involved surgical margin or close margin widths of ≤1 mm or less. PORT consisted of whole-breast irradiation (50 Gy in 25 fractions)(More)
