- Background: Patient-reported outcome instruments to assess sexual functioning typically assume that patients are heterosexual and have a single sexual partner, thus they may have limited applicability for sexual and gender minority (SGM) populations as well as for nonpartnered individuals or those with multiple partners. Aim: To explore the perceptions of SGM persons regarding the Female Sexual Function Index (FSFI), a commonly used sexual functioning questionnaire. Methods: We conducted 2 rounds of cognitive interviews with 27 SGM persons with and without a cancer diagnosis. Interviews were audio-recorded and transcribed. Two researchers independently coded the transcripts using inductive thematic analysis to identify major themes. Outcomes: Themes identified via qualitative analysis. Results: Cognitive debriefing with the participants provided critical insights about the way we ask questions about sexual functioning in the oncology clinic. Three overarching themes arose from the data: (i) Certain aspects of the questionnaire were felt to unnecessarily medicalize sexuality; (ii) FSFI domains were perceived to represent a narrow and heteronormative experience of sexuality focused on penile-vaginal intercourse; (iii) Questionnaire domains emphasizing sexual "performance" were perceived as male-oriented. Clinical implications: Questionnaires such as the FSFI that were developed in research studies with specific eligibility criteria need to be adapted to the broader population seen in clinical practice. Strengths & Limitations: Strengths of the study include purposive sampling of SGM persons through LGBTQ networks. Our sample included individuals of different sexual orientations, gender identities, marital status, and cancer histories. However, a limitation is that the the majority of the sample was white and college-educated. Other limitations of the study include the potential sampling bias of self-selected participants with a particular interest in the study questions. Conclusion: The findings provide important evidence for the development of a more inclusive sexual function measure, moving away from the traditional heteronormative, cisnormative approach to measuring sexual function.

- Purpose. To evaluate patient perceptions of a Web-based decision aid for the treatment of localized prostate cancer. Methods. We assessed patient perceptions of a multicomponent, Web-based decision aid with a preference elicitation/values clarification exercise using adaptive conjoint analysis, the generation of a summary report, and provision of information about localized prostate cancer treatment options. Using a think-aloud approach, we conducted 21 cognitive interviews with prostate cancer patients presented with the decision aid prior to seeing their urologist. Thematic content analysis was used to examine patient perceptions of the tool's components and content prior to engaging in shared decision making with their clinician. Results. Five themes were identified: 1) patients had some negative emotional reactions to the tool, pointing out what they perceived to be unnecessarily negative framing and language used; 2) patients were forced to stop and think about preferences while going through the tool and found this deliberation to be useful; 3) patients were confused by the tool; 4) patients tried to discern the intent of the conjoint analysis questions; and 5) there was a disconnect between patients' negative reactions while using the tool and a contrasting general satisfaction with the final "values profile" created by the tool. Conclusions. Studies are needed to explore the disconnect between patients' expressing negative reactions while going through some components of decision aids but satisfaction with the final output. In particular, we hypothesize that this effect might be explained by cognitive biases such as choice-supportive bias, hindsight bias, and the "IKEA effect." This is one of the first projects to elicit patient reactions while they were completing a decision aid, and we recommend further similar, qualitative postprocess evaluation studies.

- Introduction: To accommodate for the rapidly increasing patient volume and followup visits of men with prostate cancer on active surveillance (AS), we carried out a quality improvement project to secure high-quality care and enhance patient experience. Methods: We proposed an innovative clinic systems redesign-"shared medical appointments" (SMAs)-in which multiple patients were seen in a group format at the same time by the health care team led by a urologist leading the Institution's AS program. Results: We piloted four SMAs during July-November 2019. Running the SMAs was feasible and improved the contact time for each patient while at the same time being time and resource efficient for the health care providers and using the standard billing processes. The group dynamic was open and pleasant. The majority of patients rated their overall experience with SMA as excellent. Almost all patients responded that they were likely or very likely to attend another SMA in the future. All patients said that they would either definitely or probably recommend this visit type to a friend of family member with prostate cancer. Most patients rated their overall satisfaction with the SMA as extremely high. Conclusions: Utilizing SMAs for AS followup visits was feasible and acceptable. Our promising findings suggest that SMAs can ensure high-quality patient care. Well-controlled studies comparing SMAs to individual usual care visits should be conducted with end points including knowledge, patient and staff satisfaction, anxiety and quality-of-life outcomes, AS adherence, process measures and resource utilization.

- Background We assessed the concordance among urologists' judgment of health quartiles for patients with localized prostate cancer, and compared the life expectancy (LE) and ensuing treatment recommendations when following National Comprehensive Cancer Network (NCCN) guidelines based on actuarial life tables versus the Kent model, a validated LE prediction model. Methods NCCN suggests using actuarial life tables and relying on surgeon assessment of patient health to increase (for the best quartile) or decrease (for the worst quartile) LE by 50%. Eleven urologic surgeons allocated quartile of health and recommended treatments for ten patient vignettes. The 10-year survival probability was calculated using the Kent model and compared to the life-table estimate based on health quartile by surgeon consensus. Results Surgeon assessment agreed with the presumed true quartile of health based on a validated model in 41% of cases. For no case did three-quarters of surgeons assign health quartile correctly; in half of cases, <50% of surgeons assigned the correct quartile. The NCCN comorbidity-adjusted LE estimates underestimated risk of death in the best health quartile and overestimated risk of death in the worst health quartile, compared to the Kent model. Patients with LE > 10 years on NCCN estimation were recommended more frequently for surgery (81%) and those with <= 10 years estimated LE were more commonly recommended for radiation (57%) or observation (29%). Conclusions A method based on physician-assessed health quartiles for LE estimation, as suggested by the NCCN guidelines, appears too crude to be used in the treatment counseling of men with localized prostate cancer, as compared to a validated prediction model, such as the Kent model.

Tidskriftsartikel (refereegranskat)abstract
- Purpose To determine whether patient-reported collection of comorbidities online is sufficiently accurate to warrant use as part of a physician-reviewed, baseline medical history. Methods Comorbidities were collected for a sample of 213 new prostate cancer visits to our urology clinic through an online survey (called Baseline Medical History) before the clinical encounter. The frequency distributions of comorbidities as reported by patients before physician review were compared with those documented by physicians for a sample of 298 consecutive patients presenting to the same urology clinic before the survey went live. Results The overall frequency distribution of comorbidities and life expectancy estimates were similar between the two groups. A few comorbidity categories were reported with higher frequency in the patient-reported group compared with the physician-documented group, including neurologic comorbidities (7.5% v 1.7%; difference 6%; 95% CI, 2.0% to 10%; P = .001) and back pain (24% v 13%; difference 12%; 95% CI, 4.8% to 19%; P = .001). A similar trend was seen for vascular conditions, although the difference did not meet conventional levels of statistical significance. Genitourinary comorbidities, including problems with urination and erectile dysfunction, were better captured by the physician-reported group compared with the patient-reported group (68% v 53%; difference 15%; 95% CI, 7% to 24%; P = .001), as were other musculoskeletal comorbidities (8.7% v 1.9%; difference 7%; 95% CI, 3.2% to 11%; P = .001). Conclusion Patients completing a medical history, at their own pace and in the comfort of their own home, provide relatively accurate and complete information, even before physician review. Patient reporting of comorbidities thus seems to be a reliable starting point for the documentation of the medical history in the clinic.

- BackgroundPrior studies of suicide risk among prostate cancer patients are conflicting. We compared the risk of suicide in prostate cancer patients to cancer-free men including adjustment for clinical stage, socioeconomic position, somatic comorbidity, and previous depression.Materials and methodsA cohort of 37,527 men diagnosed with prostate cancer in Denmark during 1998-2011 was identified in the Danish Prostate Cancer Registry (DaPCaR) and compared with 357,384 cancer-free men matched by age at the time of diagnosis. The primary outcome was death from suicide. Data were analyzed using cumulative incidence functions and multivariable Cox regression models.ResultsAmong prostate cancer patients, 3813 had a previous depression, defined as filed antidepressant prescription within three years before diagnosis. In the study period, 108 prostate cancer patients were registered with suicide as the cause of death, hereof 26 with previous depression. There was no difference in the cumulative incidence of suicide between prostate cancer patients and cancer-free men. There was no effect modification of previous depression on the risk of suicide (p = .12). The hazard ratio (HR) for suicide varied with time since diagnosis. A sensitivity analysis showed that the risk of suicide was highest within the first year of diagnosis where prostate cancer patients had a 1.70-fold increased hazard compared with cancer-free men (95% CI, 1.11-2.59). Men with prostate cancer and previous depression had a three-fold increased hazard for suicide compared with prostate cancer patients without a history of depression (HR 2.84, 95% CI, 1.82-4.45).ConclusionThe absolute risk of suicide is low following a prostate cancer diagnosis. Time since diagnosis and a history of depression was associated with the highest risk of suicide. Healthcare professionals should be aware of an increased risk of suicide among men with previous depression, especially in the immediate aftermath of the diagnosis.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Most men with elevated levels of prostate-specific antigen (PSA) do not have prostate cancer, leading to a large number of unnecessary biopsies. A statistical model based on a panel of four kallikreins has been shown to predict the outcome of a first prostate biopsy. In this study, we apply the model to an independent data set of men with previous negative biopsy but persistently elevated PSA. METHODS: The study cohort consisted of 925 men with a previous negative prostate biopsy and elevated PSA (>= 3 ngml(-1)), with 110 prostate cancers detected (12%). A previously published statistical model was applied, with recalibration to reflect the lower positive biopsy rates on rebiopsy. RESULTS: The full-kallikrein panel had higher discriminative accuracy than PSA and DRE alone, with area under the curve (AUC) improving from 0.58 (95% confidence interval (CI): 0.52, 0.64) to 0.68 (95% CI: 0.62, 0.74), P<0.001, and high-grade cancer (Gleason >= 7) at biopsy with AUC improving from 0.76 (95% CI: 0.64, 0.89) to 0.87 (95% CI: 0.81, 0.94), P 0.003). Application of the panel to 1000 men with persistently elevated PSA after initial negative biopsy, at a 15% risk threshold would reduce the number of biopsies by 712; would miss (or delay) the diagnosis of 53 cancers, of which only 3 would be Gleason 7 and the rest Gleason 6 or less. CONCLUSIONS: Our data constitute an external validation of a previously published model. The four-kallikrein panel predicts the result of repeat prostate biopsy in men with elevated PSA while dramatically decreasing unnecessary biopsies.

- Background A pre-specified model based on four kallikrein markers in blood, commercially available as 4Kscore, predicts Gleason Grade (GG) 3 + 4 or higher prostate cancer on biopsy. However, sampling error and variation in pathology reporting may miss aggressive disease. Methods The 4Kscore was measured in cryopreserved blood from 2330 men obtained before prostatectomy at a single institution between 2002 and 2010. Adverse surgical pathology and biochemical recurrence (BCR) were pre-specified to be assessed in all men, biopsy GG 3 + 3, and 3 + 4. Results Adjusted for established clinical predictors, the 4Kscore was significantly associated with adverse pathology (OR 1.49; 95% CI 1.32, 1.67;p < 0.0001). Adding 4Kscore increased discrimination from (AUC) 0.672 to 0.718 and 0.644 to 0.659 within biopsy GG 3 + 3 and 3 + 4, respectively. Higher 4Kscore was associated with higher risk of BCR (HR 1.16, 95% CI 1.06, 1.26;p = 0.001). Adding 4Kscore improved the prediction of BCR (C-index 0.630-0.660) within GG 3 + 3, but not GG 3 + 4. Conclusions The 4Kscore can help guide the clinical decision whether additional risk assessment-such as confirmatory biopsy-is needed to decide between active surveillance versus curative therapy. Evidence that the panel could influence management in biopsy GG 3 + 4 is less strong and requires further investigation.
