- Background. Electronic patient-reported outcome measures (ePROMs) for real-time remote symptom monitoring facilitate early recognition of postoperative complications. We sought to determine whether remote, electronic, patient-reported symptom-monitoring with Recovery Tracker predicts 30-day readmission or reoperation in outpatient mastectomy patients. Methods. We conducted a retrospective review of breast cancer patients who underwent outpatient (< 24-h stay) mastectomy with or without reconstruction from April 2017 to January 2022 and who received the Recovery Tracker on Days 1-10 postoperatively. Of 5,130 patients, 3,888 met the inclusion criteria (2,880 mastectomy with immediate reconstruction and 1,008 mastectomy only). We focused on symptoms concerning for surgical complications and assessed if symptoms reaching prespecified alert levels-prompting a nursing call-predicted risk of 30-day readmission or reoperation. Results. Daily Recovery Tracker response rates ranged from 45% to 70%. Overall, 1,461 of 3,888 patients (38%) triggered at least one alert. Most red (urgent) alerts were triggered by pain and fever; most yellow (less urgent) alerts were triggered by wound redness and pain severity. The 30-day readmission and reoperation rates were low at 3.8% and 2.4%, respectively. There was no statistically significant association between symptom alerts and 30-day reoperation or readmission, and a clinically relevant increase in risk can be excluded (odds ratio 1.08; 95% confidence interval 0.8-1.46; p = 0.6). Conclusions. Breast cancer patients undergoing mastectomy with or without reconstruction in the ambulatory setting have a low burden of concerning symptoms, even in the first few days after surgery. Patients can be reassured that symptoms that do present resolve quickly thereafter.

- BackgroundThe lack of evidence-based guidelines for postoperative opioid prescriptions following breast reconstruction contributes to a wide variation in prescribing practices and increases potential for misuse and abuse.MethodsBetween August and December 2019, women who underwent outpatient breast reconstruction were surveyed 7-10 days before (n = 97) and after (n = 101) implementing a standardized opioid prescription reduction initiative. We compared postoperative opioid use, pain control, and refills in both groups. Patient reported outcomes were compared using the BREAST-Q physical wellbeing of the chest domain and a novel symptom Recovery Tracker.ResultsBefore changes in prescriptions, patients were prescribed a median of 30 pills and consumed three pills (interquartile range [IQR: 1,9]). After standardization, patients were prescribed eight pills and consumed three pills (IQR: 1,6). There was no evidence of a difference in the proportion of patients experiencing moderate to very severe pain on the Recovery Tracker or in the early BREAST-Q physical wellbeing of the chest scores (p = 0.8 and 0.3, respectively).ConclusionStandardizing and reducing opioid prescriptions for patients undergoing reconstructive breast surgery is feasible and can significantly decrease the number of excess pills prescribed. The was no adverse impact on early physical wellbeing, although larger studies are needed to obtain further data.

- Objectives Our objective was to pilot test an electronic health record-embedded decision support tool to facilitate prostate-specific antigen (PSA) screening discussions in the primary care setting. Methods We pilot-tested a novel decision support tool that was used by 10 primary care physicians (PCPs) for 6 months, followed by a survey. The tool comprised (1) a risk-stratified algorithm, (2) a tool for facilitating shared decision-making (Simple Schema), (3) three best practice advisories (BPAs: <45, 45-75, and >75 years), and (4) a health maintenance module for scheduling automated reminders about PSA rescreening. Results All PCPs found the tool feasible, acceptable, and clear to use. Eight out of ten PCPs reported that the tool made PSA screening conversations somewhat or much easier. Before using the tool, 70% of PCPs felt confident in their ability to discuss PSA screening with their patient, and this improved to 100% after the tool was used by PCPs for 6 months. PCPs found the BPAs for eligible (45-75 years) and older men (>75 years) more useful than the BPA for younger men (<45 years). Among the 10 PCPs, 60% found the Simple Schema to be very useful, and 50% found the health maintenance module to be extremely or very useful. Most PCPs reported the components of the tool to be at least somewhat useful, with 10% finding them to be very burdensome. Conclusion We demonstrated the feasibility and acceptability of the tool, which is notable given the marked low acceptance of existing tools. All PCPs reported that they would consider continuing to use the tool in their clinic and were likely or very likely to recommend the tool to a colleague.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The four-kallikrein (4K) panel has been demonstrated to improve prediction of aggressive prostate cancer compared with prostate-specific antigen (PSA) among men with moderately elevated PSA levels. However, the development and testing of the 4K panel has been conducted primarily in White men, with limited data in African Americans and no studies in other racial and ethnic groups. METHODS: We evaluated the 4K panel in a nested case-control study among African American, Latino, Japanese, Native Hawaiian, and White men in the Multiethnic Cohort. Prediagnostic blood levels of free, intact, and total PSA and human kallikrein-related peptidase 2 were measured among 1,667 incident prostate cancer cases and 691 controls with PSA ≥2 ng/mL. We evaluated the discriminative ability of the 4K panel within and across all racial/ethnic groups. RESULTS: The 4K panel enhanced discrimination of overall prostate cancer compared with free plus total PSA and total PSA alone (AUC 0.748 vs. 0.711 and 0.669, respectively). Discrimination was further enhanced for Gleason 8+ prostate cancer, aggressive prostate cancer, and death due to prostate cancer, and to a lesser degree for nonaggressive prostate cancer. Improvement of the 4K panel over PSA was observed in each population. Adding a prostate cancer polygenic risk score slightly improved upon the discriminative ability of the 4K panel. CONCLUSIONS: The superior discriminative ability of the 4K panel over PSA for overall and aggressive prostate cancer across multiethnic populations indicates the broad clinical applicability of the 4K panel. IMPACT: Our multiethnic investigation suggests potential for the 4K panel to improve current prostate cancer screening practices.

- Elevated prostate-specific antigen (PSA) levels often lead to unnecessary and possibly harmful transrectal ultrasound guided biopsy, e.g. when the biopsy is negative or contains only low-grade insignificant cancer, unlikely to become symptomatic in the man’s normal lifespan. A model based on four-kallikrein markers in blood (commercialized as 4Kscore) predicts risk of Grade group 2 or higher prostate cancer at biopsy, reducing unnecessary biopsies. We assessed whether these results extend to a single institution prostate biopsy cohort of Danish men and are enhanced by three microRNAs from urine (referred to as uCaP). The 4Kscore measured in cryopreserved blood from 234 men referred for 10+ core biopsy to Aarhus University Hospital, 29 with PSA > 25 ng/ml. We explored uCaP in urine from 157 of these men. Combined with age and DRE findings, both 4Kscore and uCaP could accurately predict Grade group 2 or higher prostate cancer (all patients: AUC = 0.802 and 0.797; PSA ≤ 25: AUC = 0.763 and 0.759). There was no additive effect when combining the 4Kscore and uCaP. Limitations include a study cohort with higher risk than commonly reported for biopsy cohorts. Our findings further support the clinical use of the 4Kscore to predict Grade group 2 or higher cancers in men being considered for biopsy.

- Objectives: Many patients experience pain, anxiety, and discomfort with prostate biopsy, which may discourage enrollment in active surveillance programs or follow-up biopsy. Guided meditation can significantly reduce pain and anxiety during percutaneous biopsy. We sought to evaluate the effectiveness of a brief mind-body intervention on patient-reported outcomes after prostate biopsy. Methods and materials: We performed a clinically-integrated randomized controlled trial of a brief mind-body intervention during biopsy compared to usual care at a single tertiary care center from 2018 to 2022. All patients offered transrectal ultrasound-guided prostate biopsy in the clinic with local anesthesia were eligible for enrollment. This clinically integrated trial was conducted simultaneously with a randomized controlled trial of 1-stage and 2-stage consent. The primary outcome was patient-reported pain, anxiety, discomfort, and tolerability on a visual-analog scale (0–10). A 15% improvement was prespecified as clinically relevant. We compared the proportion of men in each arm reporting a severe score (7–10) on any of the 4 scales using Fisher's exact test and then compared means for each scale separately using ANCOVA with randomization stratum (first vs. prior biopsy) as a covariate. Results: Of 263 eligible patients, 238 enrolled (119 per arm). One hundred seventy-two (72%) enrolled with 2-stage consent. A total of 37/94 (39%) and 38/102 (37%) patients randomized to usual care and intervention, respectively, reported severe scores in any of the 4 domains, a difference of 2.1% (95% confidence interval [CI] -13, 17%, P = 0.8). There was no evidence of a difference in mean postbiopsy anxiety (P = 0.3), discomfort (P = 0.09), pain (P = 0.4) or tolerability scores (P = 0.2). Conclusions: A clinically meaningful benefit for this brief mind-body intervention during prostate biopsy is unlikely. Robust patient enrollment is feasible using 2-stage consent.

Tidskriftsartikel (refereegranskat)abstract
- Polygenic risk scores (PRS) for prostate cancer incidence have been proposed to optimize prostate cancer screening. Prediction of lethal prostate cancer is key to any stratified screening program to avoid excessive overdiagnosis. Herein, PRS for incident prostate cancer was evaluated in two population-based cohorts of unscreened middle-aged men linked to cancer and death registries: the Västerbotten Intervention Project (VIP) and the Malmö Diet and Cancer study (MDC). SNP genotypes were measured by genome-wide SNP genotyping by array followed by imputation or genotyping of selected SNPs using mass spectrometry. The ability of PRS to predict lethal prostate cancer was compared to PSA and a commercialized pre-specified model based on four kallikrein markers. The PRS was associated with incident prostate cancer, replicating previously reported relative risks, and was also associated with prostate cancer death. However, unlike PSA, the PRS did not show stronger association with lethal disease: the hazard ratio for prostate cancer incidence vs. prostate cancer metastasis and death was 1.69 vs. 1.65 in VIP and 1.25 vs. 1.25 in MDC. PSA was a much stronger predictor of prostate cancer metastasis or death with an area-under-the-curve of 0.78 versus 0.63 for the PRS. Importantly, addition of PRS to PSA did not contribute additional risk stratification for lethal prostate cancer. We have shown that a PRS that predicts prostate cancer incidence does not have utility above and beyond that of PSA measured at baseline when applied to the clinically relevant endpoint of prostate cancer death. These findings have implications for public health policies for delivery of prostate cancer screening. Focusing polygenic risk scores on clinically significant endpoints such as prostate cancer metastasis or death would likely improve clinical utility.

- Objectives: To prospectively evaluate the performance of a pre-specified statistical model based on four kallikrein markers in blood (total prostate-specific antigen [PSA], free PSA, intact PSA, and human kallikrein-related peptidase 2), commercially available as the 4Kscore, in predicting Gleason Grade Group (GG) ≥2 prostate cancer at biopsy in an international multicentre study at three academic medical centres, and whether microseminoprotein-β (MSP) adds predictive value. Patients and Methods: A total of 984 men were prospectively enrolled at three academic centres. The primary outcome was GG ≥2 on prostate biopsy. Three pre-specified statistical models were used: a base model including PSA, age, digital rectal examination and prior negative biopsy; a model that added free PSA to the base model; and the 4Kscore. Results: A total of 947 men were included in the final analysis and 273 (29%) had GG ≥2 on prostate biopsy. The base model area under the receiver operating characteristic curve of 0.775 increased to 0.802 with the addition of free PSA, and to 0.824 for the 4Kscore. Adding MSP to the 4Kscore model yielded an increase (0.014–0.019) in discrimination. In decision-curve analysis of clinical utility, the 4Kscore showed a benefit starting at a 7.5% threshold. Conclusion: A prospective multicentre evaluation of a pre-specified model based on four kallikrein markers (4Kscore) with the addition of MSP improves the predictive discrimination for GG ≥2 prostate cancer on biopsy and could be used to inform biopsy decision-making.

- PURPOSE: To determine whether β-microseminoprotein or any of the kallikrein forms in blood-free, total or intact PSA or total hK2-predict metastasis in patients with evidence of detectable levels of PSA in blood after radical prostatectomy.METHOD: We determined marker concentrations in blood from 173 men treated with radical prostatectomy and evidence of detectable levels of PSA in the blood (PSA ≥ 0.05) after surgery between 2014 and 2015 and at least 1 year after any adjuvant therapy. We used Cox regression to determine whether any marker was associated with metastasis using both univariate and multivariable models that included standard clinical predictors.RESULTS: Overall, 42 patients had metastasis, with a median follow-up of 67 months among patients without an event. The levels of intact and free PSA and free-to-total PSA ratio were significantly associated with metastasis. Discrimination was highest for free PSA (c-index: 0.645) and free-to-total PSA ratio (0.625). Only free-to-total PSA ratio remained associated with overall metastasis (either regional or distant) after including standard clinical predictors (p = 0.025) and increased discrimination from 0.686 to 0.697. Similar results were found using distant metastasis as an outcome (p = 0.011; c-index increased from 0.658 to 0.723).CONCLUSION: Our results provide evidence that free-to-total PSA ratio can risk stratifying patients with evidence of detectable levels of PSA in blood after RP. Further research is warranted on the biology of prostate cancer markers in patients with evidence of detectable levels of PSA in blood after radical prostatectomy. Our findings on the free-to-total ratio for predicting adverse oncologic outcomes need to be validated in other cohorts.
