Few studies have demonstrated in vivo alterations of human serotonin and dopamine transporters (SERTS and DATS) during antidepressant treatment. The current study measured these transporter availabilities with [(123)I]beta-CIT single photon emission computed tomography (SPECT) during administration of selective serotonin reuptake inhibitors (SSRIs) or a(More)
BACKGROUND To the authors' knowledge, there had been no evidence for the efficacy of psychosocial intervention among Japanese cancer patients. The objective of this study was to determine the effect of a psychosocial group intervention in reducing psychologic distress and enhancing coping in this population in a randomized controlled trial. METHODS The(More)
BACKGROUND Few studies have investigated the predictive value of central serotonin transporter (SERT) availability for treatment response to serotonin reuptake inhibitors (SSRIs). This study used brain imaging to examine the relationship between pretreatment brain SERT availability and transporter occupancy by SSRIs with treatment response in two(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)
BACKGROUND High levels of distress are a concern regarding patients with head and neck cancer. Early detection of and intervention for such distress are needed to predict patients' adaptation to treatment or rehabilitation, but few studies have investigated the detection of their distress in a patient population of significant size. METHODS The authors(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)
OBJECTIVE This study investigated the effect of estrogen on brain serotonin 2A (5-HT(2A)) receptors in postmenopausal women and whether there was any correlation of receptor changes with cognition and mood. METHOD Ten postmenopausal subjects underwent positron emission tomography measurements of 5-HT(2A) receptor binding with [(18)F]deuteroaltanserin(More)
OBJECTIVE Having cancer is extremely stressful, and distressing cancer-related recollections are frequently reported by cancer survivors. Smaller hippocampal volume has been observed in stress-related neuropsychiatric disorders, such as posttraumatic stress disorder (PTSD) and major depression. The aim of this study was to determine whether there is a(More)
Though psychosocial group intervention is considered in the West to be an important source of support for reducing psychosocial distress in cancer patients, in Asian countries, there has been no research as yet on the needs for such intervention. This study investigated the level of participation and interest in psychosocial group intervention plus any(More)
This paper describes a study of the psychometric properties of the Japanese version of the mental adjustment to cancer (MAC) scale developed in England. The scale was completed by 455 Japanese cancer patients. The internal consistency was similar to that of the original version (Cronbach's alpha coefficients for the subscales ranged from 0.60 to 0.78) and(More)
