Background: During the last decade, survival rates for breast cancer have increased as a result of earlier detection and use adjuvant therapy. Limited data exist on psychosocial aspects transitional period between end primary treatment survivorship. We investigated baseline status women enrolled in randomized trial testing two interventions at treatment. Methods: Participants, identified within 1 month after surgery (registration), provided demographic information limited measures quality...

Purpose Evidence suggests that the re-entry phase (ie, early period after medical treatment completion) presents distinct challenges for cancer patients. To facilitate transition to recovery, we conducted Moving Beyond Cancer (MBC) trial, a multisite, randomized, controlled trial of psychoeducational interventions breast Methods Breast patients were registered within 6 weeks surgery. After treatment, they completed baseline measures and randomly assigned standard National Institute print...

Spirituality is a multidimensional construct, and little known about how its distinct dimensions jointly affect well-being. In longitudinal studies (Study 1, n = 418 breast cancer patients; Study 2, 165 survivors), the authors examined 2 components of spiritual well-being (i.e., meaning/peace faith) their interaction, as well change scores on those variables, predictors psychological adjustment. higher baseline meaning/peace, an increase in over 6 months, predicted decline depressive...

Background: Various groups have called for a national system to monitor the quality of cancer care. The validity registry data care has not been well studied. We investigated such information in California Cancer Registry. Methods: compared associated with abstracted from medical records patients diagnosed breast cancer. also calculated score each subject by determining proportion four evidence-based indicators that were met and then overall scores obtained record data. All statistical tests...

Cognitive complaints are reported frequently after breast cancer treatments. Their association with neuropsychological (NP) test performance is not well-established. Early-stage, posttreatment patients were enrolled in a prospective, longitudinal, cohort study prior to starting endocrine therapy. Evaluation included an NP battery and self-report questionnaires assessing symptoms, including cognitive complaints. Multivariable regression models assessed associations among complaints, mood,...

Decision making for treatment of localized prostate cancer is often guided by therapeutic side-effect profiles. We sought to assess health-related quality-of-life outcomes patients 48 months after cancer. Men treated (N = 475) were evaluated before and at 11 intervals during the intervention. Changes in mean scores probability regaining baseline levels quality life compared between groups. All statistical tests two-sided. Urinary incontinence was more common prostatectomy (n 307) than...

Men with low-risk prostate cancer and significant comorbidity are susceptible to overtreatment. The authors sought compare the impact of age on treatment choice in men disease.The sampled 509 diagnosed at Greater Los Angeles Long Beach Veterans Affairs Medical Centers between 1997 2004. Rates aggressive (radical prostatectomy, radiation therapy, brachytherapy) were determined among different ages Charlson scores.

Abstract Spirituality is interdependent with the biological, psychological, and interpersonal aspects of life. Although spirituality has been studied in breast cancer survivors, little work done men prostate cancer. We sought to determine whether lower early stage associated worse general health‐related quality life (HRQOL), disease‐specific HRQOL, or psychosocial health. Two hundred twenty‐two subjects were drawn from a state‐funded program providing free treatment indigent men. Validated...
