Goal-Focused Emotion-Regulation Therapy (GET) in Young Adult Testicular Cancer Survivors: A Randomized Pilot Study.

BACKGROUND: Young adult testicular cancer survivors experience adverse impacts after treatment. We developed Goal-focused Emotion-regulation Therapy (GET) to improve distress symptoms, emotion regulation, and goal navigation skills. PURPOSE: This pilot study examined GET versus an active control intervention in young adult survivors of testicular cancer. METHODS: Seventy-five eligible survivors treated with chemotherapy were randomized to receive GET or Individual Supportive Listening (ISL). Study acceptability, engagement, and tolerability were examined, and intervention fidelity and therapeutic alliance were compared between arms. Preliminary efficacy was evaluated by effect sizes for between-group changes in primary (anxiety and depressive symptoms) and secondary (career confusion, goal navigation, and emotion regulation) outcomes from baseline to immediately and 3-month post-intervention. RESULTS: Among the 38 men randomized to GET, 81.1% completed all study sessions compared with 82.4% of the 37 men assigned to ISL. Fidelity to the intervention was 87% in GET. Therapeutic alliance wassignificantly higher among those receiving GET versus ISL. Participants exhibited a medium group-by-time effect size with greater reductions in depressive (d = 0.45) and anxiety (d = 0.29) symptoms for those in GET versus ISL, with a similar pattern at 3 months for depressive (d = 0.46) and anxiety (d = 0.46) symptoms. CONCLUSIONS: GET is a feasible and acceptable intervention for reducing adverse outcomes after testicular cancer for young adults. Observed effect sizes preliminarily suggest meaningful change, though should be interpreted with caution in small samples. GET may be a developmentally-matched behavioral approach to improve psychosocial function in this cancer group. CLINICAL TRIAL INFORMATION: Clinicaltrials.gov, NCT04150848.

Young adult testicular cancer survivors experience adverse impacts after treatment. Goal-focused Emotion-regulation Therapy (GET) was developed to improve distress symptoms, emotion regulation, and goal navigation skills. The aim of this pilot study was to examine GET versus a control intervention in young adult survivors of testicular cancer. Seventy-five survivors were randomly assigned to GET or Individual Supportive Listening (ISL). Indictors of acceptability, engagement, and tolerability were examined, and intervention fidelity and therapeutic alliance were compared between groups. Between-group changes in primary (anxiety and depressive symptoms) and secondary (career confusion, goal navigation, and emotion regulation) outcomes from baseline to immediately and 3-month post-intervention were examined. Among GET participants, 81.1% completed all study sessions compared with 82.4% of those receiving ISL. Fidelity to the intervention was 87% in GET. Therapeutic alliance scores were significantly higher among those receiving GET. Participants exhibited greater reductions in depressive and anxiety symptoms for those in the GET versus ISL, with a similar pattern observed for changes at 3 months for depressive and anxiety symptoms. GET is a feasible and acceptable intervention for reducing adverse outcomes after testicular cancer for young adults.

Using Prostate Imaging-Reporting and Data System (PI-RADS) Scores to Select an Optimal Prostate Biopsy Method: A Secondary Analysis of the Trio Study.

BACKGROUND: While magnetic resonance imaging (MRI)-targeted biopsy (TBx) results in better prostate cancer (PCa) detection relative to systematic biopsy (SBx), the combination of both methods increases clinically significant PCa detection relative to either Bx method alone. However, combined Bx subjects patients to higher number of Bx cores and greater detection of clinically insignificant PCa. OBJECTIVE: To determine if prebiopsy prostate MRI can identify men who could forgo combined Bx without a substantial risk of missing clinically significant PCa (csPC). DESIGN, SETTING, AND PARTICIPANTS: Men with MRI-visible prostate lesions underwent combined TBx plus SBx. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcomes were detection rates for grade group (GG) ≥2 and GG ≥3 PCa by TBx and SBx, stratified by Prostate Imaging-Reporting and Data System (PI-RADS) score. RESULTS AND LIMITATIONS: Among PI-RADS 5 cases, nearly all csPCs were detected by TBx, as adding SBx resulted in detection of only 2.5% more GG ≥2 cancers. Among PI-RADS 3-4 cases, however, SBx addition resulted in detection of substantially more csPCs than TBx alone (8% vs 7.5%). Conversely, TBx added little to detection of csPC among men with PI-RADS 2 lesions (2%) relative to SBx (7.8%). CONCLUSIONS: While combined Bx increases the detection of csPC among men with MRI-visible prostate lesions, this benefit was largely restricted to PI-RADS 3-4 lesions. Using a strategy of TBx only for PI-RADS 5 and combined Bx only for PI-RADS 3-4 would avoid excess biopsies for men with PI-RADS 5 lesions while resulting in a low risk of missing csPC (1%). PATIENT SUMMARY: Our study investigated an optimized strategy to diagnose aggressive prostate cancer in men with an abnormal prostate MRI (magnetic resonance imaging) scan while minimizing the risk of excess biopsies. We used a scoring system for MRI scan images called PI-RADS. The results show that MRI-targeted biopsies alone could be used for men with a PI-RADS score of 5, while men with a PI-RADS score of 3 or 4 would benefit from a combination of MRI-targeted biopsy and systematic biopsy. This trial is registered at ClinicalTrials.gov as NCT00102544.

Why Does Magnetic Resonance Imaging-Targeted Biopsy Miss Clinically Significant Cancer?

PURPOSE: Multiple studies demonstrate magnetic resonance imaging (MRI)-targeted biopsy detects more clinically significant cancer than systematic biopsy; however, some clinically significant cancers are detected by systematic biopsy only. While these events are rare, we sought to perform a retrospective analysis of these cases to ascertain the reasons that MRI-targeted biopsy missed clinically significant cancer which was subsequently detected on systematic prostate biopsy. MATERIALS AND METHODS: Patients were enrolled in a prospective study comparing cancer detection rates by transrectal MRI-targeted fusion biopsy and systematic 12-core biopsy. Patients with an elevated prostate specific antigen (PSA), abnormal digital rectal examination, or imaging findings concerning for prostate cancer underwent prostate MRI and subsequent MRI-targeted and systematic biopsy in the same setting. The subset of patients with grade group (GG) ≥3 cancer found on systematic biopsy and GG ≤2 cancer (or no cancer) on MRI-targeted biopsy was classified as MRI-targeted biopsy misses. A retrospective analysis of the MRI and MRI-targeted biopsy real-time screen captures determined the cause of MRI-targeted biopsy miss. Multivariable logistic regression analysis compared baseline characteristics of patients with MRI-targeted biopsy misses to GG-matched patients whose clinically significant cancer was detected by MRI-targeted biopsy. RESULTS: Over the study period of 2007 to 2019, 2,103 patients met study inclusion criteria and underwent combined MRI-targeted and systematic prostate biopsies. A total of 41 (1.9%) men were classified as MRI-targeted biopsy misses. Most MRI-targeted biopsy misses were due to errors in lesion targeting (21, 51.2%), followed by MRI-invisible lesions (17, 40.5%) and MRI lesions missed by the radiologist (3, 7.1%). On logistic regression analysis, lower Prostate Imaging-Reporting and Data System (PI-RADSTM) score was associated with having clinically significant cancer missed on MRI-targeted biopsy. CONCLUSIONS: While uncommon, most MRI-targeted biopsy misses are due to errors in lesion targeting, which highlights the importance of accurate co-registration and targeting when using software-based fusion platforms. Additionally, some patients will harbor MRI-invisible lesions which are untargetable by MRI-targeted platforms. The presence of a low PI-RADS score despite a high PSA is suggestive of harboring an MRI-invisible lesion.

Partial versus total adrenalectomy for pheochromocytoma: a population-based comparison of outcomes.

PURPOSE: The literature assessing outcomes of partial adrenalectomy (PA) among patients with pheochromocytoma patients is largely limited to isolated, single-institution series. We aimed to perform a population-level comparison of outcomes between patients undergoing PA versus those undergoing total adrenalectomy (TA). METHODS: The Surveillance, Epidemiology, and End Results (SEER) database (1975-2016) was queried to identify adults with pheochromocytoma who underwent either PA or TA. Survival was assessed using multivariable Cox proportional hazards regression, Fine and Gray competing-risks regression, propensity score matching, Kaplan-Meier analysis, and cumulative incidence plots. RESULTS: 286 patients (PA: 101, TA: 185) were included in this study. As compared to those undergoing TA, patients undergoing PA had fewer tumors ≥ 8 cm in size (28.7% versus 42.7%, p = 0.048) and were more likely to have localized disease (61.4% versus 44.3%, p = 0.01). In multivariable analysis, patients undergoing PA demonstrated similar all-cause mortality (HR = 0.71, 95% CI 0.44-1.14, p = 0.16) and cancer-specific mortality (HR = 0.64, 95% CI 0.35-1.17, p = 0.15) compared to those who underwent TA. Following 1:1 propensity score matching, Kaplan-Meier analysis revealed no difference in overall survival between PA and TA groups (p = 0.26) nor was there a difference in the cumulative incidence of cancer-specific mortality (p = 0.29). CONCLUSIONS: In this first population-level comparison of outcomes among patients with pheochromocytoma undergoing PA and those undergoing TA, we found no long-term differences in any survival metric between groups. PA circumvents the need for lifelong corticoid replacement therapy and remains a promising option for patients with bilateral or recurrent pheochromocytoma.

The Risk of Prostate Cancer Progression in Active Surveillance Patients with Bilateral Disease Detected by Combined Magnetic Resonance Imaging-Fusion and Systematic Biopsy.

PURPOSE: We sought to evaluate whether bilateral prostate cancer detected at active surveillance (AS) enrollment is associated with progression to Grade Group (GG) ≥2 and to compare the efficacy of combined targeted biopsy plus systematic biopsy (Cbx) vs systematic biopsy (Sbx) or targeted biopsy alone to detect bilateral disease. MATERIALS AND METHODS: A prospectively maintained database of patients referred to our institution from 2007-2020 was queried. The study cohort included all AS patients with GG1 on confirmatory Cbx and followup of at least 1 year. Cox proportional hazard analysis identified baseline characteristics associated with progression to ≥GG2 at any point throughout followup. RESULTS: Of 579 patients referred, 103 patients had GG1 on Cbx and were included in the study; 49/103 (47.6%) patients progressed to ≥GG2, with 30/72 (41.7%) patients with unilateral disease progressing and 19/31 (61.3%) patients with bilateral disease progressing. Median time to progression was 68 months vs 52 months for unilateral and bilateral disease, respectively (p=0.006). Both prostate specific antigen density (HR 1.72, p=0.005) and presence of bilateral disease (HR 2.21, p=0.012) on confirmatory biopsy were associated with AS progression. At time of progression, GG and risk group were significantly higher in patients with bilateral versus unilateral disease. Cbx detected 16% more patients with bilateral disease than Sbx alone. CONCLUSIONS: Bilateral disease and prostate specific antigen density at confirmatory Cbx conferred greater risk of earlier AS progression. Cbx was superior to Sbx for identifying bilateral disease. AS risk-stratification protocols may benefit from including presence of bilateral disease and should use Cbx to detect bilateral disease.

Risk of adverse pathology at prostatectomy in the era of MRI and targeted biopsies; rethinking active surveillance for intermediate risk prostate cancer patients.

PURPOSE: Men with intermediate risk (IR) prostate cancer (CaP) are often excluded from active surveillance (AS) due to higher rates of adverse pathology (AP). We determined our rate of AP in men who underwent multiparametric MRI (MpMRI) with combined biopsy (CB) consisting of targeted biopsy (TB) and systematic biopsy (SB) prior to radical prostatectomy (RP). METHODS: A retrospective review was conducted of men with Gleason Grade Group (GG) 2 disease who underwent RP after SB alone or after preoperative MRI with CB. AP was defined as either pathologic stage T3a (AP ≥ T3a) or pathologic stage T3b (AP ≥ T3b) and/or GG upgrading. Rates of AP were determined for both groups and those who fit the National Comprehensive Cancer Network (NCCN) definition of favorable IR (FIR) or the low volume IR (LVIR) criteria. Multivariable logistic regression was used to determine predictive factors. RESULTS: The overall rate of AP ≥ T3b was 21.2% in the SB group vs. 8.6% in the MRI with CB group, P = 0.006. This rate was lowered to 6.8% and 5.6% when men met the definition of NCCN FIR or LVIR, respectively. Suspicion for extraprostatic extension (EPE) (OR 7.65, 95% CI 1.77-33.09, P = 0.006) and positive cores of GG 2 on SB (OR 1.43, 95% CI 1.05-1.96, P = 0.023) were significant for predicting AP ≥ T3b. CONCLUSIONS: Rates of AP at RP after MRI with CB are lower than studies prior to the adoption of this technology, suggesting that more men with IR disease may be considered for AS. However, increasing cores positive on SB and MRI findings suggestive of EPE remain unsafe.

Chemical Perturbation of Oncogenic Protein Folding: from the Prediction of Locally Unstable Structures to the Design of Disruptors of Hsp90-Client Interactions.

Protein folding quality control in cells requires the activity of a class of proteins known as molecular chaperones. Heat shock protein-90 (Hsp90), a multidomain ATP driven molecular machine, is a prime representative of this family of proteins. Interactions between Hsp90, its co-chaperones, and client proteins have been shown to be important in facilitating the correct folding and activation of clients. Hsp90 levels and functions are elevated in tumor cells. Here, we computationally predict the regions on the native structures of clients c-Abl, c-Src, Cdk4, B-Raf and Glucocorticoid Receptor, that have the highest probability of undergoing local unfolding, despite being ordered in their native structures. Such regions represent potential ideal interaction points with the Hsp90-system. We synthesize mimics spanning these regions and confirm their interaction with partners of the Hsp90 complex (Hsp90, Cdc37 and Aha1) by Nuclear Magnetic Resonance (NMR). Designed mimics selectively disrupt the association of their respective clients with the Hsp90 machinery, leaving unrelated clients unperturbed and causing apoptosis in cancer cells. Overall, selective targeting of Hsp90 protein-protein interactions is achieved without causing indiscriminate degradation of all clients, setting the stage for the development of therapeutics based on specific chaperone:client perturbation.

Preprinted standardized orders promote venous thromboembolism prophylaxis compared with traditional handwritten orders: an endorsement of standardized evidence-based practice.

The objective was to determine if a standardized process of care--namely, standardized evidence-based medical orders (SEBMOs)--improves physician compliance with venous thromboembolism (VTE) prophylaxis. A total of 61 physicians received information about VTE prophylaxis after introduction of an admission SEBMO. Hospitalists received enhanced presentations about SEBMOs and their value in VTE prevention; specialists did not. Data were analyzed for 2 cohorts of 249 at-risk patients: one cohort was admitted with SEBMOs and the other with handwritten orders. VTE prophylaxis was ordered for 70% (173 of 249) of the SEBMO cohort compared with 22% (55 of 249) of patients whose physicians handwrote orders (relative risk ratio = 2.97; 95% confidence interval = 2.33-3.79; P < .0001). Specialists, who did not receive the enhanced education, were more likely to use handwritten orders and less likely to comply with prophylaxis standards. Standardized orders promote VTE prophylaxis more than handwritten orders. More rigorous education is required to promote compliance with evidence-based standards of medical practice.
