The present study sought to determine the prevalence of acute and delayed chemotherapy-induced nausea and vomiting (CINV) across ten community oncology settings. The effect of CINV on quality of life (QOL) was also evaluated. Cancer patients who were scheduled for their first cycle of a new chemotherapy regimen were recruited from ten community oncology(More)
BACKGROUND Research suggests that stress-reduction programs tailored to the cancer setting help patients cope with the effects of treatment and improve their quality of life. Yoga, an ancient Eastern science, incorporates stress-reduction techniques that include regulated breathing, visual imagery, and meditation as well as various postures. The authors(More)
This study examined the effects of yoga on quality of life (QOL) and psychosocial outcomes in women with breast cancer undergoing radiotherapy. Sixty-one women were randomly assigned to either a yoga or a wait-list group. Yoga classes were taught biweekly during the 6 weeks of radiotherapy. Participants completed measures of QOL, fatigue, benefit finding(More)
BACKGROUND Huachansu, a Chinese medicine that comes from dried toad venom from the skin glands of Bufo gargarizans or B. melanostictus, has been used in the treatment of various cancers in China. The authors conducted a pilot study, using a phase 1 trial design, of huachansu in patients with advanced cancer. METHODS Huachansu was administered(More)
Amidst confusion about the nature and usefulness of the stress construct and distinctions between acute and chronic stress, research has begun to identify mechanisms by which stress affects health and by which stress can persist beyond the physical presence of the stressor. In addition, research has begun to identify reasons for selective vulnerability to(More)
In recent years, there has been increasing emphasis on understanding how the cancer experience affects individuals' quality of life (QOL). The goal of this study was to assess the QOL and to identify psychosocial predictors of QOL among a large sample of patients with a variety of cancers. Specifically, we assessed the unique contribution of demographic(More)
The various surgical procedures for early-stage breast cancer are equivalent in terms of survival. Therefore, other factors, such as the procedures’ effect on psychosocial adjustment and quality of life (QOL), take on great importance. The aim of the current study was to prospectively examine the short- and long-term effects of mastectomy with(More)
PURPOSE Evidence has supported the association between psychological factors and cancer biology; however, findings are equivocal on the role of psychosocial factors in cancer progression. This study generates a hypothesis of mechanistic variables by examining the clinical effects of psychosocial factors and cortisol dysregulation in patients with metastatic(More)
Colorectal cancer patients usually receive treatments (e.g., pelvic surgery or radiotherapy, colostomy) that increase their risk for sexual problems. Previous research has mainly focused on demographic and medical risk factors. Because little is known about the role of psychosocial variables in sexual dysfunction, this research sought to identify the(More)
