Objective: To assess the health-related quality of life (HRQoL) of patients with prostate cancer up to 24 months after treatment in a contemporary large diverse population., Patients and Methods: Patients with newly diagnosed prostate cancer from March 2011 to January 2014 in our healthcare system were included. The Expanded Prostate Cancer Index Composite (EPIC-26) questionnaire was administered before treatment, and at 1, 3, 6, 12, 18, and 24 months after treatment up to November 2014 for all methods of treatment. The Kruskall-Wallis test was used to compare the distribution of each EPIC-26 domain score at each time point, and mixed models were used to assess the overall scores over the period after treatment., Results: In all, 5 727 patients were included. There were data for 3 422, 2 329, 2 017, 1 922, 1 772, 1 260, and 837 patients before treatment, and at 1, 3, 6, 12, 18, and 24 months after treatment, respectively. At 1 month, bowel scores were the lowest for patients that had had radiation therapy, and urinary irritative symptoms were the lowest for those who had had brachytherapy. There were sexual function declines for all the treatment methods, with surgery having the steepest decline; open radical prostatectomy (ORP) had a greater decline than robot-assisted laparoscopic prostatectomy (RALP). Patients who underwent RALP had a better return of sexual function, approaching that of brachytherapy and radiation therapy at 24 months. Urinary incontinence (UI) also declined the most in surgical patients, with RALP patients improving slightly more than ORP patients at 12-24 months., Conclusions: Patients' HRQoL after prostate cancer treatment varies by treatment method. Notably, sexual function recovers most for RALP patients. UI remains worse at 24 months after surgery, compared to other methods of prostate cancer treatment., (© 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.)

Objectives: To characterise the progression and treatment of lower urinary tract symptoms (LUTS) among men aged 45-69 years in the California Men's Health Study., Patients and Methods: A total of 39,222 men, aged 45-69 years, enrolled in the Southern California Kaiser Permanente Health Plan were surveyed in 2002-2003 and again in 2006-2007. Those men who completed both surveys who did not have a diagnosis of benign prostatic hyperplasia (BPH) and were not on medication for LUTS at baseline were included in the study (N = 19,505). Among the men with no or mild symptoms at baseline, the incidence of moderate/severe LUTS (American Urological Association Symptom Index [AUASI] score ≥8) and odds of progression to severe LUTS (AUASI score ≥20) was estimated during 4 years of follow-up., Results: Of the 9640 men who reported no/mild LUTS at baseline, 3993 (41%) reported moderate/severe symptoms at follow-up and experienced a 4-point change in AUASI score on average. Of these men, 351 (8.8%) had received a pharmacological treatment, eight (0.2%) had undergone a minimally invasive or surgical procedure and 3634 (91.0%) had no treatment recorded. Men who progressed to severe symptoms (AUASI score ≥20; n = 165) were more likely to be on medication for BPH (odds ratio [OR] 8.09, 95% confidence interval [CI] 5.77-11.35), have a BPH diagnosis (OR 4.74, 95% CI 3.40-6.61) or have seen a urologist (OR 2.49, 95% CI 1.81-3.43) when compared with men who did not progress to severe symptoms (AUASI score <20)., Conclusion: These data show that the majority of men who experienced progression did not have pharmacological or surgical therapy for their symptoms and, therefore, may prove to be good candidates for a self-management plan., (© 2014 The Authors.

Objective: To determine whether the rate of change in total serum prostate-specific antigen (PSA) levels accurately detects prostate cancer and to evaluate whether it adds any predictive value to a single measurement of serum PSA alone, in general practice settings., Materials and Methods: A retrospective cohort of 219,388 community-dwelling men, aged ≥45 years, enrolled in the Kaiser Permanente Southern California health plan, with no history of prostate cancer and at least three PSA measurements, were followed from 1 January 1998 to 31 December 2007, for the development of biopsy-confirmed prostate cancer. Annual percent changes in total serum PSA levels were estimated using linear mixed models. The accuracy of prostate cancer prediction was assessed for prostate cancer overall and for aggressive disease (Gleason score ≥7) and compared with that of a single measure of PSA level using area under the receiver-operating characteristic curves (AUCs)., Results: The men in this cohort experienced a mean change of 2.9% in PSA levels per year and the rate of change in PSA increased modestly with age (P ≤ 0.001). Annual percent changes in PSA accurately predicted the presence of prostate cancer (AUC = 0.963) and aggressive disease (AUC = 0.955) and had more predictive accuracy for aggressive disease than did a single measurement of PSA alone (AUC = 0.727)., Conclusions: Longitudinal measures of PSA improve the accuracy of aggressive prostate cancer detection when compared with a single measurement of PSA alone. Findings from this study provide insight into the usefulness of PSA velocity as a detection marker for aggressive prostate cancer., (© 2013 BJU International.)

Unlabelled: Study Type - Symptom prevalence (population cohort). Level of Evidence 1b. What's known on the subject? and What does the study add? It is known that medical conditions such as diabetes, high blood pressure, high cholesterol, smoking and prescribed medications cause erectile dysfunction (ED). This has been studied at the molecular level and reported in population studies. The present study shows that, after accounting for known medical problems, there is a dose-response relationship, in which worsening degrees of ED are seen when a greater number of medications are taken, regardless if they are prescribed or over the counter. The study can help primary care doctors and urologists to make a differential diagnosis of ED and it can also help improve patient's erectile function by tailoring and curtailing current medication use to maximize therapeutic benefit but minimize ED side effects in men, thus improving health-related quality of life., Objective: • To study the association between erectile dysfunction (ED) and polypharmacy use in a large, ethnically and racially diverse cohort of men enrolled in the California Men's Health Study (CMHS)., Patients and Methods: • Men from the Kaiser Permanente Southern California (KPSC) health plan, enrolled in the CMHS in 2002, had an age range of 45-69 years. ED and comorbidities of these subjects were identified by questionnaire responses. • The number of drugs taken was determined from the year before enrollment through electronic pharmacy records and questionnaire responses., Results: • Among the 37 712 (KPSC) subjects, 10 717 (29%) reported moderate or severe ED. • Across all age groups, ED was more prevalent as the number of medications increased. • In men taking 0-2, 3-5,6-9 and ≥ 10 medications, the percentage of men reporting moderate ED was 15.9, 19.7, 25.5 and 30.9%, respectively (P < 0.001). • With adjustment for age, race, smoking, diabetes, hypertension, hyperlipidaemia, peripheral vascular disease, coronary artery disease and body mass index, men taking >10 drugs were more likely to have ED (odds ratio = 2.32, 95% confidence interval 2.14-2.52) with evidence of a dose-response relationship., Conclusion: • These data suggest that the number of medications a man takes is associated with worse ED, even after comorbidities have been taken into account., (© 2011 BJU INTERNATIONAL.)
