BACKGROUND Previous studies have shown cognitive impairment in breast cancer survivors who were exposed to adjuvant chemotherapy. Neural damage by chemotherapy might have played some part in these findings. The current study explored the regional brain volume difference between breast cancer survivors exposed to adjuvant chemotherapy (C+) and those(More)
BACKGROUND Psychological distress is frequently observed, however, it is underestimated in cancer patients. The aim of this study is to develop a simple battery for screening for psychological distress, adjustment disorder and major depressive disorder in Japanese cancer patients. METHODS One hundred and twenty-eight cancer patients were interviewed by(More)
Cancer patients frequently suffer from a myriad of symptoms. The development and application of comprehensive assessment tools is essential to the effective management of these symptoms. The M.D. Anderson Symptom Inventory (MDASI), developed in English, is a brief, self-rating multiple symptom assessment scale that consists of 13 symptom items and 6(More)
PURPOSE Provision of supportive care to meet patients' individual needs is instrumental to enhancing their quality of life. We therefore need an appropriate assessment tool to measure such needs. The purpose of this study was to examine the psychometric property of the Japanese version of the Short-form Supportive Care Needs Survey questionnaire(More)
We investigated the adverse effects of adjuvant chemotherapy on the hippocampus in Japanese breast cancer survivors with (n=44) and without (n=31) adjuvant chemotherapy. There were no significant differences in hippocampal volume (magnetic resonance imaging) or additionally in memory function (Wechsler Memory Scale-Revised) between the two groups.
Neuropsychological studies of obsessive-compulsive disorder (OCD) have pointed to memory and attention deficits among its sufferers, but these reports have largely ignored the possibility that cognitive disturbances may vary across OCD clinical subtypes, or that their interactions may differ between subtypes. The purpose of the present study was to(More)
 Fatigue is one of the most frequent symptoms in cancer patients. However, the precise causes of this fatigue are still unknown, and this situation makes it difficult to combat the problem. The present study was conducted to investigate factors correlated with fatigue in disease-free breast cancer patients. A group of 134 randomly selected ambulatory breast(More)
We herein describe the development and validation of the Cancer Fatigue Scale (CFS) for assessment of fatigue in cancer patients. We designed this scale specifically to reflect the nature of fatigue experienced by cancer patients, by using factor analysis; the CFS is a 15-item scale composed of 3 subscales (physical, affective, and cognitive subscales).(More)
BACKGROUND Adjustment disorders and major depression are common psychiatric disorders in patients with cancer and have a serious impact on quality of life. The problem in clinical oncology settings is underrecognition of these disorders; as a result, screening is recommended to detect them. The goal of the current study was to develop a new, brief screening(More)
Screening cancer patients for adjustment disorders and major depression is important, because both are prevalent and often underrecognized. The purpose of this study was to validate the Distress and Impact Thermometer, a 2-item questionnaire, which we newly developed as a brief screening tool for detection of adjustment disorders and/or major depression.(More)
