- BACKGROUND:Studies enumerating the dynamics of physical and emotional symptoms following prostate cancer (PCa) treatment are needed to guide therapeutic strategy. Yet, overcoming patient selection forces is a formidable challenge for observational studies comparing treatment groups.OBJECTIVE:To compare patterns of symptom burden and distress in men with localized PCa randomized to radical prostatectomy (RP) or watchful waiting (WW) and followed up longitudinally.DESIGN, SETTING, AND PARTICIPANTS:The three largest, Swedish, randomization centers for the Scandinavian Prostate Cancer Group-4 trial conducted a longitudinal study to assess symptoms and distress from several psychological and physical domains by mailed questionnaire every 6 mo for 2 yr and then yearly through 8 yr of follow-up.INTERVENTION:RP compared with WW.OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS:A questionnaire was mailed at baseline and then repeatedly during follow-up with questions concerning physical and mental symptoms. Each analysis of quality of life was based on a dichotomization of the outcome (yes vs no) studied in a binomial response, generalized linear mixed model.RESULTS AND LIMITATIONS:Of 347 randomized men, 272 completed at least five questionnaires during an 8-yr follow-up period. Almost all men reported that PCa negatively influenced daily activities and relationships. Health-related distress, worry, feeling low, and insomnia were consistently reported by approximately 30-40% in both groups. Men in the RP group consistently reported more leakage, impaired erection and libido, and fewer obstructive voiding symptoms. For men in the WW group, distress related to erectile symptoms increased gradually over time. Symptom burden and distress at baseline was predictive of long-term outlook.CONCLUSIONS:Cancer negatively influenced daily activities among almost all men in both treatment groups; health-related distress was common. Trade-offs exist between physiologic symptoms, highlighting the importance of tailored treatment decision-making. Men who are likely to experience profound long-term distress can be identified early in disease management.

- Background: Radical prostatectomy reduces mortality among patients with localised prostate cancer. Evidence on whether different surgical techniques can affect mortality rates is lacking. Objective: To evaluate functional and oncological outcomes 8 yr after robot-assisted laparoscopic prostatectomy (RALP) and open retropubic radical prostatectomy (RRP). Design, setting, and participants: We enrolled 4003 patients in a prospective, controlled, nonrandomised trial comparing RALP and RRP in 14 Swedish centres between 2008 and 2011. Data for functional outcomes were assessed via validated patient questionnaires administered preoperatively and at 12 and 24 mo and 8 yr after surgery. Outcome measurements and statistical analysis: The primary endpoint was urinary incontinence. Functional outcomes at 8 yr were analysed using the modified Poisson regression approach. Results and limitations: Urinary incontinence was not significantly different at 8 yr after surgery between RALP and RRP (27% vs 29%; adjusted risk ratio [aRR] 1.05, 95% confidence interval [CI] 0.90–1.23). Erectile dysfunction was significantly lower in the RALP group (66% vs 70%; aRR 0.93, 95% CI 0.87–0.99). Prostate cancer–specific mortality (PCSM) was significantly lower in the RALP group at 8 yr after surgery (40/2699 vs 25/885; aRR 0.56, 95% CI 0.34–0.93). Differences in oncological outcomes were mainly seen in the group with high D'Amico risk, with a lower risk of positive surgical margins (21% vs 34%), biochemical recurrence (51% vs 69%), and PCSM (14/220 vs 11/77) for RALP versus RRP. The main limitation is the nonrandomised design. Conclusions: In this prospective multicentre controlled trial, PCSM at 8 yr after surgery was lower for RALP in comparison to RRP. A causal relationship between surgical technique and mortality cannot be inferred, but the result confirms that RALP is oncologically safe. Taken together with better short-term results reported elsewhere, our findings confirm that implementation of RALP may continue. Patient summary: Our study comparing two surgical techniques for removal of the prostate for localised prostate cancer shows that a robot-assisted minimally invasive technique is safe in the long term. Together with previous results showing some better short-term effects with this approach, our findings support continued use of robot-assisted surgery.

- Background: Whether surgeons perform better utilising a robot-assisted laparoscopic technique compared with an open approach during prostate cancer surgery is debatable. Objective: To report erectile function and early oncologic outcomes for both surgical modalities, stratified by prostate cancer risk grouping. Design, setting, and participants: In a prospective nonrandomised trial, we recruited 2545 men with prostate cancer from seven open (n = 753) and seven robot-assisted (n = 1792) Swedish centres (2008-2011). Outcome measurements and statistical analysis: Clinometrically-validated questionnaire-based patient-reported erectile function was collected before, 3 mo, 12 mo, and 24 mo after surgery. Surgeon-reported degree of neurovascular-bundle preservation, pathologist-reported positive surgical margin (PSM) rates, and 2-yr prostate-specific antigen-relapse rates were measured. Results and limitations: Among 1702 preoperatively potent men, we found enhanced erectile function recovery for low/intermediate-risk patients in the robot-assisted group at 3 mo. For patients with high-risk tumours, point estimates for erectile function recovery at 24 mo favoured the open surgery group. The degree of neurovascular bundle preservation and erectile function recovery were greater correlated for robot-assisted surgery. In pT2 tumours, 10% versus 17% PSM rates were observed for open and robot-assisted surgery, respectively; corresponding rates for pT3 tumours were 48% and 33%. These differences were associated with biochemical recurrence in pT3 but not pT2 disease. The study is limited by its nonrandomised design and relatively short follow-up. Conclusions: Earlier recovery of erectile function in the robot-assisted surgery group in lower-risk patients is counterbalanced by lower PSM rates for open surgeons in organ-confined disease; thus, both open and robotic surgeons need to consider this trade-off when determining the plane of surgical dissection. Robot-assisted surgery also facilitates easier identification of nerve preservation planes during radical prostatectomy as well as wider dissection for pT3 cases. Patient summary: For prostate cancer surgery, an open operation reduces erection problems in high-risk cancers but has higher relapse rates than robotic surgery. Relapse rates appear similar in low/intermediate-risk cancers and the robot appears better at preserving erections in these cases. Robot-assisted surgery appears to improve erectile function recovery compared with open radical prostatectomy for low- and intermediate-risk tumours, whereas the opposite is true for high-risk disease. Margin and recurrence rates are worse for open surgical patients with pT3 disease.

- Background: There is increasing low-quality evidence rationalizing the use of radical therapy for men at high risk of disseminated prostate cancer. Objective: To investigate, using high-quality epidemiologic data, whether initial radical therapy in men at high risk of disseminated prostate cancer improves survival. Design, setting, and participants: An observational population-based Swedish study from 1996 to 2010 of men at high risk of disseminated prostate cancer (prostate-specific antigen [PSA] > 50) initially treated by radical therapy (radiation therapy [n = 630] or radical prostatectomy [n = 120]) or androgen deprivation therapy (n = 17 602), and followed for up to 15 yr. Outcome measurements and statistical analysis: Prostate-cancer and other-cause mortality was estimated for the treatment groups. We also matched the two cohorts for grade, T stage, M stage, Charlson score, year of diagnosis, age, and PSA, and found androgen deprivation therapy patient matches for 575 of the radical therapy patients, and then repeated comparative effectiveness analyses. Results and limitation: Prostate-cancer mortality was substantially greater in the androgen deprivation therapy group compared with the radically treated one, in unmatched (9062/17 602 vs 86/750) and matched (177/575 vs 71/575) cohorts. Among matched cohorts, initial androgen deprivation therapy was associated with nearly three-fold higher hazard of prostate-cancer death compared with initial radical therapy (2.87; 95% confidence interval 2.16-3.82). Multiple sensitivity analyses suggested that the findings were robust, although the general limitations of nonrandomized studies remain. Further, the study cohort may have included men with both systemic and nonsystemic disease, as a sole eligibility criterion of PSA > 50 was used. Conclusions: This large and comprehensive population-based study suggests that initial radical therapy in men at high risk of disseminated prostate cancer improves survival. Patient summary: This large Swedish study suggests that men with prostate cancer that has spread beyond the prostate benefit from treating the prostate itself with radiation therapy or surgery rather than treating the disease with hormones alone.
