Predictors of quality of life after radical treatment for prostate cancer

INTRODUCTION: The usual treatment options for clinically localized prostate cancer carry a significant risk of lasting side effects, including urinary, bowel, and sexual dysfunction, that can alter overall the patient's quality of life. The aim of this research is to evaluate the impact of treatment timing (age at time of treatment, follow-up duration, age at time of follow-up), pretreatment tumor characteristics (clinical stage, Gleason score, PSA), and posttreatment outcomes (hormonal status, biochemical recurrence), on health-related quality of life (HRQOL) among men who had undergone radical treatment for prostate cancer. MATERIALS AND METHODS: 595 patients with prostate cancer who had undergone either radical prostatectomy or external beam radiation as primary therapy between 1988 and 2000 were selected for this retrospective, cross-sectional study. The enrolled subjects were asked to complete the Italian validated version of University of California-Los Angeles Prostate Cancer Index. Clinical parameters, hormone therapy status and posttreatment outcomes were considered to perform uni- and multivariate analyses. RESULTS: Both uni- and multivariate analyses demonstrated that timing of radical treatment is a critical predictive factor for sexual activity. Pretreatment tumor characteristics had a significant impact on urinary function, urinary bother and sexual function. Hormone treatment exclusively influenced sexual function and sexual bother, while biochemical recurrence can also worsen urinary symptoms and urinary bother. CONCLUSION: Our findings suggest that treatment timing, pretreatment tumor characteristics and posttreatment outcomes may have an impact on HRQOL in patients who have undergone radical treatment for prostate cancer: all these items should be considered in order to achieve an accurate interpretation of prostate cancer treatment outcomes

Prevalence, incidence estimation, risk factors and characterization of chronic prostatitis/chronic pelvic pain syndrome in urological hospital outpatients in Italy: results of a multicenter case-control observational study.

PURPOSE: We evaluated the prevalence and estimated the incidence and risk factors of chronic prostatitis/chronic pelvic pain syndrome in urological hospital outpatients in Italy. MATERIALS AND METHODS: From January to June 2006 patients from 28 Italian urological centers who were between 25 and 50 years old with symptoms of chronic prostatitis/chronic pelvic pain syndrome were consecutively enrolled in this prospective epidemiological case-control study. A total of 152 subjects of similar age, race and area of origin who were investigated for infertile couples but were otherwise healthy served as controls. All subjects provided a medical history and underwent different symptom scorings, clinical evaluation and microbiological tests. RESULTS: Of 5,540 male urological outpatients 764 with chronic prostatitis/chronic pelvic pain syndrome were enrolled, including 225 (29.4%) at the first presentation and 539 (70.6%) who underwent previous treatment. Thus, the prevalence of the syndrome was 13.8%, while the estimated incidence was 4.5%. Cigarette smoking, a high caloric diet with low fruit and vegetable consumption, constipation, meteorism, slow digestion, a sexual relationship with more than 1 partner and coitus interruptus were more likely in patients with chronic prostatitis/chronic pelvic pain syndrome than in controls (each p <0.001). The syndrome had a negative influence on sexual desire, erectile dysfunction and premature ejaculation (p <0.001). The Meares and Stamey test was positive in 13.3% of patients and in 2.9% of controls. Urethral swabs in patients with a negative Meares and Stamey test were positive for sexually transmitted pathogens in 6%. CONCLUSIONS: The prevalence and estimated incidence of chronic prostatitis/chronic pelvic pain syndrome in urological hospital outpatients in Italy are high. The syndrome is closely related to lifestyle, diet, smoking, gastrointestinal or anorectal disease and impaired sexual functio

How legislation on decisional capacity can negatively affect the feasibility of clinical trials in patients with dementia

Antipsychotic drugs are widely used to treat behavioural and psychological disturbances associated with Alzheimer's disease (AD), although only modest evidence from randomized controlled trials supports their efficacy, and increasing evidence from post-marketing surveillance shows serious adverse events associated with their use, including increased mortality. The AdCare study, a non-profit, randomized, placebo-controlled, double-blind, multicentre, pragmatic trial coordinated by the Italian National Institute of Health, aimed to evaluate the long-term safety and efficacy profiles of three atypical antipsychotic drugs (risperidone, olanzapine and quetiapine) and one conventional antipsychotic drug (haloperidol) in treating psychosis, aggression and agitation in outpatients with AD. The study was planned to be carried out in 19 clinical centres and to enrol 1000 outpatients. According to Italian law, in the case where a patient is considered unable to give informed consent, a legal representative designated by the court has to provide it. Because of difficulties in the informed consent procedure, the study had to be prematurely interrupted. From February 2009 to April 2010, 83 patients gave informed consent to participate in the trial. Fifty-six patients (68%) were included with consent given by a legal representative, while 27 patients (32%) were considered to provide personal informed consent on the basis of the results from a specifically built procedure. Patients and caregivers were offered the opportunity to participate in the trial before the occurrence of behavioural disturbances, in order to provide them with enough time to consider their participation in the study. Twenty-three patients experienced behavioural, clinically relevant symptoms and were randomized to the study drug; all randomized patients except one had consent for inclusion in the study given by legal representatives. After trial interruption, all patients taking an active drug continued treatment with the same molecule in clinical practice. Randomized controlled trials are acknowledged as the gold standard source of evidence on drug safety and efficacy. The AdCare study showed that an excessively rigid regulation can become a major obstacle while carrying out therapeutic research with incapacitated persons
