Exploratory factor analysis: strategies used by patients to promote health.

Strategies used by patients to promote health (SUPPH) was used to measure self-care self-efficacy in patients with cancer. The objectives of this study were (1) to determine the extent to which self-efficacy theory explained the factor structure of the SUPPH and (2) to determine the relationship of demographic data with factors of the SUPPH. Subjects were diagnosed with prostate cancer (PCa) and treated with either: (a) radical prostatectomy, (b) intensity modulated radiation therapy (IMRT) + radioactive seed implantation, or (c) IMRT + high dose rate.

Prospective study of quality of life of patients receiving treatment for prostate cancer.

Background: No research was found that compared quality of life (QOL) outcomes of prostate cancer patients receiving intensity-modulated radiation therapies with prostate cancer patients receiving radical prostatectomy.

Objectives: To (a) describe differences in QOL before and after three types of treatment for prostate cancer: radical prostatectomy, intensity-modulated radiation therapy + seed implantation (permanent brachytherapy), or intensity-modulated radiation therapy + high dose rate radiotherapy (temporary brachytherapy); and (b) investigate demographic, physical, and psychosocial variables that impact QOL of men with prostate cancer.

Methods: Data were collected on three occasions: baseline (prior to treatment), 1 month, and 3 months after beginning treatment.

Prostate HDR radiation therapy: a comparative study evaluating the effectiveness of pain management with peripheral PCA vs. PCEA.

Introduction: High dose rate (HDR) brachytherapy is considered one of the most advanced treatment technologies currently available for treatment of localized prostate cancer. It gives the advantage of applying higher dose radiation, with greater precision, directly to the tumor while sparing healthy tissue and surrounding organs, thereby resulting in fewer side effects. In this facility, the treatment requires an overnight stay in the hospital, in a supine position, with a perineal template sutured to the perineum to prevent catheter movement or dislodgement.

Review of vitamin E and selenium in the prevention of prostate cancer: implications of the selenium and vitamin E chemoprevention trial.

The National Cancer Institute in cooperation with the Southwest Oncology Group has begun one of the largest prostate cancer prevention studies to date, the Selenium and Vitamin E Chemoprevention Trial (SELECT). The purpose of this article is to review the evidence and discuss the individual antioxidant compounds under study. The authors comprehensively reviewed the peer-reviewed literature on the chemoprevention of prostate cancer with emphasis on the antioxidants vitamin E and selenium.

The effects of edema on urethral dose following palladium-103 prostate brachytherapy.

The effects of edema on urethral dose after interstitial prostate brachytherapy with palladium-103 (103Pd) were studied. Fifty patients underwent a 90-Gy 103Pd implant followed by dosimetric computed tomography (CT). Twenty-one days later, a Foley catheter was reinserted and a dosimetric CT was repeated.
