RESUMO

PURPOSE OF REVIEW: This narrative review aims to outline the current available evidence, challenges, and future perspectives of Artificial Intelligence (AI) in the diagnosis and management of priapism, a condition marked by prolonged and often painful erections that presents unique diagnostic and therapeutic challenges. RECENT FINDINGS: Recent advancements in AI offer promising solutions to face the challenges in diagnosing and treating priapism. AI models have demonstrated the potential to predict the need for surgical intervention and improve diagnostic accuracy. The integration of AI models into medical decision-making for priapism can also predict long-term consequences. AI is currently being implemented in urology to enhance diagnostics and treatment work-up for various conditions, including priapism. Traditional diagnostic approaches rely heavily on assessments based on history, leading to potential delays in treatment with possible long-term sequelae. To date, the role of AI in the management of priapism is understudied, yet to achieve dependable and effective models that can reliably assist physicians in making decisions regarding both diagnostic and treatment strategies.

RESUMO

BACKGROUND: Submuscular reservoir placement has fulfilled a critical need for patients desiring multicomponent penile implants following pelvic surgery and radiation therapy. Passage of the reservoir through the inguinal canal into the submuscular space is often challenging and carries the risk of the reservoir being placed unknowingly outside of the targeted space. AIM: To evaluate the safety and accuracy of a direct vision, transfascial (DVT) approach to submuscular reservoir placement. METHODS: We retrospectively reviewed outcomes for consecutive patients undergoing DVT submuscular reservoir placement abstracted from a large IRB-approved database at our institution. Postimplant cross-sectional imaging performed on many of these patients was used to ascertain the final location of the reservoir. OUTCOMES: Outcome measures included the perioperative and intermediate-term safety and complications of the procedure. Postimplant imaging ascertained the accuracy in providing patients with a submuscular reservoir. RESULTS: There were 107 DVT submuscular reservoirs placed in 100 consecutive patients. No intraoperative complications occurred, there were no postoperative rectus hematomas, and there were 4 (3.7%) postoperative infections. With a mean follow up of 17.5 +/- 20.5 months there was one reservoir herniation, one patient had autoinflation, and one patient required repositioning of a high riding pump. There were 4 mechanical malfunctions requiring revision at a median of 74 months (range: 69-108 months.) following implant placement. Of the 43 patients who underwent imaging: 34 (79%) reservoirs were accurately positioned, 5 (12%) were in the lateral abdominal wall, 1(2%) was in the retroperitoneum, and 3 (7%) were intraperitoneal. Intraperitoneal reservoirs occurred exclusively in postcystectomy patients. CLINICAL IMPLICATIONS: The DVT approach is technically safe, although a slightly higher than expected infection risk was noted. It provides accurate reservoir placement for the majority of imaged patients. Postcystectomy patients have a risk of insidious intraperitoneal reservoir placement. Preoperative counseling should mention this and postimplant imaging may be considered for some of these patients. Imaging may also helpful prior to future revision surgery in order to identify and remove insidious intraperitoneal reservoirs. STRENGTHS AND LIMITATIONS: We investigated 100 patients, almost half underwent cross sectional imaging. Weaknesses include the retrospective nature of this single-institutional study, which may not have similar outcomes at other centers. CONCLUSION: DVT submuscular reservoir placement is safe following pelvic surgery and radiation therapy. Despite careful and deliberate surgical technique imaging found that approximately 20% of reservoirs are not in their expected location. Intraperitoneal reservoirs are of concern, particularly in postcystectomy patients. Kava BR, Levine A, Hauser N, et al.

RESUMO

BACKGROUND: Prostate artery embolization (PAE) is an emerging therapy for lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). AIM: This retrospective study was conducted to assess the effect of prostate artery embolization (PAE) on erectile function in a cohort of patients with LUTS attributable to BPH at 3-months after the procedure. METHODS: A retrospective review was performed on 167 patients who underwent PAE. Data collected included Sexual Health Inventory in Men (SHIM) scores at 3, 6, and 12 months post-PAE, in conjunction with the International Prostate Symptom Scores (IPSS), Quality of Life (QoL) scores, and prostate volumes. Primary outcome was erectile function as assessed by SHIM scores at 3 months after PAE. An analysis was performed to identify patients with a ±5-point SHIM change to group them according to this minimum clinically significant difference in erectile function. Adverse events were recorded using the Clavien-Dindo (CD) classification. OUTCOMES: At 3 months following PAE, median IPSS decreased by 16.0 [IQR, 9.0-22.0] points, median QOL decreased by 4.0 [IQR, 2.0-5.0] points, and median prostate volume decreased by 33 g [IQR, 14-55]. RESULTS: Median SHIM score was 17.0 [IQR, 12.0-22.0] at baseline, 18.0 [IQR, 14.0-23.0] at 3 months [P = .031], 19.0 [IQR, 14.5-21.5] at 6 months [P = .106] and 20 [IQR, 16.0-24.0] at 12 months [P = .010] following PAE. In patients with no erectile dysfunction (ED) at baseline, 21% (n = 9) reported some degree of decline in erectile function post-PAE. However, 38% (n = 40) of patients who presented with mild-to-moderate ED reported improvement in their erectile function 3 months following PAE. Overall, the changes in baseline SHIM score were relatively small; 82% (n = 137) of patients did not have more than 5 points of change in their SHIM scores at 3 months following PAE. CLINICAL IMPLICATIONS: Our findings suggest PAE has no adverse impact on erectile function for most patients. STRENGTHS & LIMITATIONS: The study was performed at a single center with 1 operator's experience, and is retrospective with no control group. CONCLUSION: Findings suggest that prostate artery embolization has no adverse effect on erectile function in the majority of patients with LUTS attributable to BPH at 3 months after the procedure.

RESUMO

PURPOSE: Genomic prognostic signatures are used on prostate biopsy tissue for cancer risk assessment, but tumor heterogeneity and multifocality may be an issue. We evaluated the variability in genomic risk assessment from different biopsy cores within the prostate using 3 prognostic signatures (Decipher, CCP, GPS). MATERIALS AND METHODS: Men in this study came from 2 prospective prostate cancer trials of patients undergoing multiparametric magnetic resonance imaging and magnetic resonance imaging targeted biopsy with genomic profiling of positive biopsy cores. We explored the relationship among tumor grade, magnetic resonance imaging risk and genomic risk for each signature. We evaluated the variability in genomic risk assessment between different biopsy cores and assessed how often magnetic resonance imaging targeted biopsy or the current standard of care (profiling the core with the highest grade) resulted in the highest genomic risk level. RESULTS: In all, 224 positive biopsy cores from 78 men with prostate cancer were profiled. For each signature, higher biopsy grade (p <0.001) and magnetic resonance imaging risk level (p <0.001) were associated with higher genomic scores. Genomic scores from different biopsy cores varied with risk categories changing by 21% to 62% depending on which core or signature was used. Magnetic resonance imaging targeted biopsy and profiling the core with the highest grade resulted in the highest genomic risk level in 72% to 84% and 75% to 87% of cases, respectively, depending on the signature used. CONCLUSIONS: There is variation in genomic risk assessment from different biopsy cores regardless of the signature used. Magnetic resonance imaging directed biopsy or profiling the highest grade core resulted in the highest genomic risk level in most cases.

RESUMO

PURPOSE: Ischemic priapism is a urological emergency that requires prompt intervention to preserve erectile function. Characteristics that influence escalation to surgical intervention remain unclear. We identified factors and developed machine learning models to predict which men presenting with ischemic priapism will require shunting. MATERIALS AND METHODS: We identified men with ischemic priapism admitted to the emergency department of our large county hospital between January 2010 and June 2019. We collected patient demographics, etiology, duration of priapism prior to intervention, interventions attempted and escalation to shunting. Machine learning models were trained and tested using R to predict which patients require surgical shunting. RESULTS: A total of 334 encounters of ischemic priapism were identified. The majority resolved with intracavernosal phenylephrine injection and/or cavernous aspiration (78%). Shunting was required in 10% of men. Median duration of priapism before intervention was longer for men requiring shunting than for men who did not (48 vs 7 hours, p=0.030). Patients with sickle cell disease as the etiology were less likely to require shunting compared to all other etiologies (2.2% vs 15.2%, p=0.035). CONCLUSIONS: Men with longer duration of priapism before treatment more often underwent shunting. However, phenylephrine injection and aspiration remained effective for priapism lasting more than 36 hours. Having sickle cell disease as the etiology of priapism was protective against requiring shunting. We developed artificial intelligence models that performed with 87.2% accuracy and created an online probability calculator to determine which patients with ischemic priapism may require shunting.

RESUMO

PURPOSE: We applied nonmuscle invasive bladder cancer AUA (American Urological Association)/SUO (Society of Urologic Oncology) guidelines for risk stratification and analyzed predictors of recurrence and progression. MATERIALS AND METHODS: We retrospectively reviewed the records of 398 patients with nonmuscle invasive bladder cancer treated between 2001 and 2017. Descriptive statistics were used to compare AUA/SUO risk groups. Predictors of recurrence and progression were determined by multivariable regression. Kaplan-Meier analysis was done, a Cox proportional hazards regression model was created and time dependent AUCs were calculated to determine progression-free and recurrence-free survival by risk group. RESULTS: Median followup was 37 months (95% CI 35-42). Of the patients 92% underwent bacillus Calmette-Guérin induction and 46% received at least 1 course of maintenance treatment. Of the patients 11.5% were at low, 32.5% were at intermediate and 55.8% were at high risk. In patients at low, intermediate and high risk the 5-year progression-free survival rate was 93%, 74% and 54%, and the 5-year recurrence-free survival rate was 43%, 33% and 23%, respectively. Kaplan-Meier analysis was done to stratify high grade Ta 3 cm or less tumor recurrence-free and progression-free survival in the intermediate vs the high risk group. Relative to low risk, classification as intermediate and as high risk was an independent predictor of progression (HR 9.7, 95% CI 2.23-42.0, p <0.01, and HR 36, 95% CI 8.16-159, p <0.001, respectively). Recurrence was more likely in patients at high risk than in those at low risk (HR 2.03, 95% CI 1.11-3.71, p=0.022). For recurrence and progression the 1-year AUC was 0.60 (95% CI 0.546-0.656) and 0.68 (95% CI 0.622-0.732), respectively. CONCLUSIONS: The AUA/SUO nonmuscle invasive bladder cancer risk classification system appropriately stratifies patients based on the likelihood of recurrence and progression. It should be used at diagnosis to counsel patients and guide therapy.

RESUMO

INTRODUCTION: With the increasing utilization of ectopic reservoir placement during multicomponent penile implant surgery, safety concerns have been raised about whether passing the reservoir through the floor of the inguinal canal consistently results in placement of the reservoir within the correct location. AIM: To evaluate the safety, efficacy, and patient satisfaction associated with direct-vision, trans-fascial sub muscular reservoir placement in consecutive patients who had previously undergone radical cystectomy. METHODS: Perioperative data, complications, and follow up for the 12 cystectomy patients were evaluated using a comprehensive database of consecutive patients undergoing penile prosthesis placement at our center. Efficacy and patient satisfaction were based upon responses to the Erectile Function and Satisfaction Domains of the International Index of Erectile Function (IIEF). Taking advantage of the need for post cystectomy imaging in monitoring for cancer recurrence, we reviewed post- implant imaging with the purpose of ascertaining the final reservoir location. MAIN OUTCOME MEASURE: Using intraoperative photographs, we describe the technique of trans-fascial sub muscular reservoir placement. Perioperative complications, device efficacy and satisfaction, and the accuracy of reservoir placement are also evaluated. RESULTS: Average patient age was 65 ± 7 years old and the mean time between cystectomy and implant placement was 41 ± 29 months. With a mean follow up of 26 ± 21 months, complications included: 1 reservoir herniation and 1 high riding pump requiring repositioning. Mean IIEF-EF domain was 29.8 ± 0.5 and mean IIEF-satisfaction domain was 17.7 ± 4.5. Other than the herniated reservoir, imaging confirmed accurate reservoir placement in 8 of 9 cases. In 3 patients a small cephalad portion of the reservoir extends posteriorly into the peritoneal or preperitoneal space, with no clinical consequences. CLINICAL IMPLICATIONS: Ectopic reservoir placement using a trans-fascial submuscular approach seems to be a safe method for multicomponent penile implant surgery in patients who have undergone radical cystectomy. Post-implant imaging confirms that the device is consistently placed in the correct sub muscular location. STRENGTHS & LIMITATIONS: This is a novel approach to performing the procedure and a practical manner to ascertain the reservoir position. The limited number of patients prevents generalization of our findings. CONCLUSION: Trans-fascial, sub muscular reservoir placement is a safe means of ectopically placing the reservoir of a multicomponent penile implant following radical cystectomy. Post implant IIEF scores indicate high device efficacy and patient satisfaction. Post implant imaging confirms that the reservoir is almost always in the desired location.

RESUMO

BACKGROUND: Fungal infections of inflatable penile prostheses (IPPs) are inadequately understood in the literature. AIM: To review a multi-institution database of IPP infections to examine for common patient and surgical factors related to IPP fungal infections. METHODS: This is a retrospective Institutional Review Board-approved analysis of 217 patients at 26 institutions who underwent salvage or device explant between 2001 and 2018. Patient data were compiled after an extensive record review. OUTCOMES: 26 patients (12%) with fungal infections were identified. RESULTS: 23 of 26 patients (83%) with a fungal IPP infection were either diabetic or overweight. 15 patients had undergone primary IPP implantation, and the other 11 had previously undergone an average of 1.7 IPP-related surgeries (range 1-3; median 2). The average age at implantation was 63 years (range 31-92; median 63). 18 of the 26 patients with fungal infection had diabetes (69%), with a mean hemoglobin A1c (HbA1c) value of 8.4 (range 5.8-13.3; median 7.5). Twenty-two patients (85%) were overweight or obese. The mean body mass index for all patients was 30.1 kg/m2 (range 23.7-45 kg/m2; median 28.4 kg/m2), and that for diabetic patients was 30.8 kg/m2 (range 24.1-45 kg/m2, median 29.7 kg/m2). Ninety-one percent of implants were placed with intravenous antibiotics, consistent with current American Urological Association guidelines: an aminoglycoside plus first- or second-generation cephalosporin or vancomycin or ampicillin/sulbactam or piperacillin/tazobactam. 65% (17 of 26) of infected IPPs had only fungal growth in culture. No patient had concomitant immunosuppressive disease or recent antibiotic exposure before IPP implantation. CLINICAL IMPLICATIONS: More than two-thirds of the fungal infections occurred in diabetic patients and 85% occurred in overweight or obese patients, suggesting that antifungal prophylaxis may be appropriate in these patients. STRENGTHS & LIMITATIONS: This is the largest series of fungal infections reported to date in the penile prosthesis literature. The overall number of such cases, however, remains small. CONCLUSION: Fungal infections represent 12% of all penile prosthesis infections in our series and were seen mostly in diabetic or overweight patients, who may benefit from antifungal prophylaxis.

RESUMO

PURPOSE OF REVIEW: Inflatable penile prosthesis (IPP) is a treatment for erectile dysfunction. IPPs have undergone improvements; however, post-surgical infections still occur. Furthermore, the type of pathogens infecting the implants has changed recently from Gram-positive to Gram-negative bacteria and fungi due to advances in antibiotic dips targeting the skin flora. To protect against infection, the AMS 700 is pre-coated with InhibiZone (mixture of Rifampin/Minocycline) and the Coloplast Titan, with several antibiotic dip options of differing efficacies. This review discusses strategies to decrease the infection rates in implant surgery, focusing on antibiotic dips. RECENT FINDINGS: Current research endorses the use of rifampin/gentamicin as the most studied combination; however, some studies have utilized different dips for additional coverage including the InhibiZone on the AMS 700. With the increasing prevalence of diabetes and Gram-negative organisms, there is a need to develop strategies for increased coverage against infections. Controlled studies with different antibiotic combinations are needed to identify the ideal cocktail to decrease infection.

RESUMO

PURPOSE: Removal of an infected penile implant often results in corporeal fibrosis, irreversible penile shortening and dissatisfaction with future implant surgery. Salvage surgery may avoid these problems but to our knowledge no study to date has evaluated these specific end points. We evaluated patients who presented to our center with an infected implant to determine the impact of salvage surgery on penile length. MATERIALS AND METHODS: We evaluated consecutive patients undergoing removal of an infected penile prosthesis with immediate salvage or delayed reimplantation using a comprehensive, prospective database. Total corporeal length prior to and following immediate salvage or delayed reimplantation were compared. The impact of patient age, comorbidities, bacterial species, initial penile length and time to reimplantation on subsequent total corporeal length was evaluated. RESULTS: The cohort consisted of 40 patients. Overall 81% of salvaged cases were successful, resulting in a mean 0.6 cm (95% CI 0.20 to 1.1) reduction in total corporeal length. Delayed reimplantation resulted in a mean 3.7 cm (95% CI 2.9-4.5) total corporeal length loss. In patients who underwent delayed reimplantation the total corporeal length reduction was directly proportionate to the initial penis size of the patient. No statistically significant impact on penile length was attributable to patient age, diabetes, bacterial species or time to reimplantation. CONCLUSIONS: When possible, salvage surgery should be offered to patients with an infected penile implant. Our data confirmed that successful salvage surgery preserves penile length. When a device is explanted and replaced at a later date, patients can expect to lose 15% to 30% of penile length irrespective of age, diabetes, type of infecting organism and time to reimplantation.

RESUMO

PURPOSE: To evaluate the safety and efficacy of prostate artery embolization (PAE) for the treatment of benign prostatic hyperplasia for prostates ≥ 80 mL. PATIENTS AND METHODS: A retrospective review was conducted of 93 patients with prostate volumes (PVs) ≥ 80 mL treated with PAE from April 2014 through October 2017. Mean patient age was 68.5 years (range 52-88) and mean age-adjusted Charlson comorbidity index was 3.2 (range 1-8). Exclusion criteria included history of biopsy-proven prostate cancer or catheter dependency. Clinical and urodynamic outcomes were reviewed at 1, 3, 6, and 12 months. Adverse events were graded according to the Clavien-Dindo classification. RESULTS: Mean PV decreased significantly from 141.7 mL to 98.1 mL at 3 months (P < .01) and 82.2 mL at 12 months (P < .01). Significant improvements were seen in 3- and 12-month mean International Prostate Symptom Scores (IPSS) (22.3 vs 7.1 and 7.3, respectively; P < .01 for both), quality of life (QOL) (4.4 vs 1.2 and 1.3; P < .01 for both), and postvoid residual volume (196.7mL vs 92.1 and 61.2 mL; P < .01 and P < .01, respectively). Significant improvement was also seen in 3-month mean maximum urinary flow: 7.7 mL/s vs 12.8 mL/s (P < .01). One grade II complication of stroke occurred; all other complications were self-limited and grade I. CONCLUSIONS: PAE achieved a clinically and statistically significant improvement in symptom burden and secondary outcome measures in patients with PVs ≥ 80 mL. PAE may be an alternate treatment for patients for whom conventional surgical options are limited or associated with significant morbidity.

RESUMO

PURPOSE: To evaluate efficacy and safety of prostate artery embolization (PAE) in urinary catheter-dependent patients with large prostate volumes and high comorbidity scores. MATERIALS AND METHODS: A retrospective single-center review was conducted of 30 patients with urinary retention at time of PAE from November 2014 through February 2017. Mean (range) age was 73.1 years (48-94 y), age-adjusted Charlson comorbidity index was 4.5 (0-10), duration of urinary retention was 63.4 days (2-224 d), International Prostate Symptom Score quality-of-life (IPSS-QOL) was 5.3 (3-6), and prostate volume was 167.3 cm3 (55-557 cm3). These parameters were collected at 3, 6, and 12 months after PAE. Trials of voiding were performed approximately 2 weeks after PAE and, if failed, every 2 weeks thereafter. Adverse events were graded using the Clavien-Dindo classification. RESULTS: At a mean (range) of 18.2 days (1-72 d), 26 (86.7%) patients were no longer reliant on catheters. Follow-up was obtained in all patients eligible at 3 and 6 months and 17 of 20 (85.0%) patients eligible at 1 year. Mean (range) IPSS-QOL improved significantly to 1.2 (0-5), 0.7 (0-4), and 0.6 (0-4) at 3, 6, and 12 months (all P < .001). Mean (range) prostate volume decreased significantly to 115.9 cm3 (27-248 cm3) at 3 months (P < .001). Two patients experienced grade II urosepsis complications, which were successfully treated with intravenous antibiotics. All other complications were self-limited grade I complications. CONCLUSIONS: PAE represents a safe and effective option for management of patients with urinary retention, especially patients with large prostates who are not ideal surgical candidates.

RESUMO

OBJECTIVE: Few studies have examined the impact of cultural processes prevalent in minority ethnic groups such as cancer fatalism and medical mistrust on health-related quality of life (HRQoL) following a cancer diagnosis. The present study examined relationships among ethnicity, HRQoL, and two possible cultural vulnerability factors-fatalistic attitudes and medical mistrust-among an ethnically diverse sample of men with prostate cancer (PC) prior to undergoing active treatment. METHODS: A total of 268 men with localized PC (30% African American, 29% Hispanic, and 41% non-Hispanic White) were assessed cross-sectionally prior to active treatment. Path analyses examined relationships among ethnicity, vulnerability factors, and HRQoL. RESULTS: Ethnicity was not related to HRQoL after controlling for relevant covariates. Hispanic men reported greater cancer fatalism compared with non-Hispanic White men (ß = 0.15, p = 0.03), and both Hispanics (ß = 0.19, p < 0.01) and African Americans (ß = 0.20, p < 0.01) reported greater medical mistrust than non-Hispanic Whites. Fatalism demonstrated a trend toward negatively impacting physical well-being (ß = -0.12, p = 0.06), but was not significantly related to emotional well-being (ß = -0.10, p = 0.11). Greater medical mistrust was associated with poorer physical (ß = -0.14, p = 0.03) and emotional well-being (ß = -0.13, p = 0.04). CONCLUSIONS: Results indicate that fatalistic attitudes and medical system mistrust were more prevalent among minority men. Less trust in the medical system was associated with poorer physical and emotional well-being. Attention to perceptions of the healthcare system and its relation to HRQoL may have implications for targeting culturally driven attitudes that may compromise adjustment to a PC diagnosis.Copyright © 2015 John Wiley & Sons, Ltd.

RESUMO

INTRODUCTION: Sarcoidosis is a multisystem disease that commonly involves the lungs, but may also present with extrapulmonary manifestations. Genitourinary (GU) tract involvement has been traditionally thought to be rare, but that view may underestimate the true prevalence of the disease due to the often, silent presentation thereof. METHODS: The literature pertaining to sarcoidosis from the general systemic point of view, etiology and therapy and with regard to specific organs was reviewed by identifying key words in a PubMed search. That material with special relevance to the Indian experience was emphasized. RESULTS: There are a number of isolated case reports in the literature describing symptomatic and asymptomatic GU tract sarcoidosis. The world literature associated with the generalized syndrome was reviewed and summarized. Specific aspects of GU involvement are presented for each organ of the GU tract. CONCLUSIONS: It is critical for the practicing clinician to have a working knowledge of the clinical manifestations of this disease as it involves the GU tract, as well as to be able to distinguish it from tuberculosis and the various malignancies that affect this organ system.

RESUMO

PURPOSE: Previous studies have demonstrated significant variation in recurrence rates after transurethral resection of bladder tumor, likely due to differences in surgical quality. We sought to create a framework to define, measure and improve the quality of transurethral resection of bladder tumor using a surgical checklist. MATERIALS AND METHODS: We formed a multi-institutional group of urologists with expertise with bladder cancer and identified 10 critical items that should be performed during every high quality transurethral bladder tumor resection. We prospectively implemented a 10-item checklist into practice and reviewed the operative reports of such resections performed before and after implementation. Results at all institutions were combined in a meta-analysis to estimate the overall change in the mean number of items documented. RESULTS: The operative notes for 325 transurethral bladder tumor resections during checklist use were compared to those for 428 performed before checklist implementation. Checklist use increased the mean number of items reported from 4.8 to 8.0 per resection, resulting in a mean increase of 3.3 items (95% CI 1.9-4.7) on meta-analysis. With the checklist the percentage of reports that included all 10 items increased from 0.5% to 27% (p <0.0001). Surgeons who reported more checklist items tended to have a slightly higher proportion of biopsies containing muscle, although not at conventional significance (p = 0.062). CONCLUSIONS: The use of a 10-item checklist during transurethral resection of bladder tumor improved the reporting of critical procedural elements. Although there was no clear impact on the inclusion of muscle in the specimen, checklist use may enhance surgeon attention to important aspects of the procedure and be a lever for quality improvement.

RESUMO

OBJECTIVE: To analyze the association between prediagnostic prostate-specific antigen kinetics and the risk of biopsy progression in prostate cancer patients on active surveillance, and to study the effect of prediagnostic prostate-specific antigen values on the predictive performance of prostate-specific antigen velocity and prostate-specific antigen doubling time. METHODS: The study included 137 active surveillance patients with two or more prediagnostic prostate-specific antigen levels measured over a period of at least 3 months. Two sets of analyses were carried out. First, the association between prostate-specific antigen kinetics calculated using only the prediagnostic prostate-specific antigen values and the risk of biopsy progression was studied. Second, using the same cohort of patients, the predictive value of prostate-specific antigen kinetics calculated using only post-diagnostic prostate-specific antigens and compared with that of prostate-specific antigen kinetics based on both pre- and post-diagnostic prostate-specific antigen levels was analyzed. RESULTS: Of 137 patients included in the analysis, 37 (27%) had biopsy progression over a median follow-up period of 3.2 years. Prediagnostic prostate-specific antigen velocity of more than 2 ng/mL/year and 3 ng/mL/year was statistically significantly associated with the risk of future biopsy progression. However, after adjustment for baseline prostate-specific antigen density, these associations were no longer significant. None of the tested prostate-specific antigen kinetics based on combined pre- and post-diagnostic prostate-specific antigen values were statistically significantly associated with the risk of biopsy progression. CONCLUSIONS: Historical prediagnostic prostate-specific antigens seems to be not clinically useful in patients diagnosed with low-risk prostate cancer on active surveillance.

RESUMO

UNLABELLED: Advanced prostate cancer patients often undergo androgen deprivation therapy (ADT). Advanced disease and adverse ADT side effects are often debilitating and negatively impact mood. Social support has been shown to mitigate detrimental effects of stress on mood. OBJECTIVE: This study sought to characterize positive and negative mood in this select patient population and determine whether social support moderated relations between stress and mood. METHODS: Participants (N = 80) completed the Interpersonal Support Evaluation List, Perceived Stress Scale, and Derogatis Affect Balance Scale at a single time point. Hierarchical regression models evaluated relations among social support, stress, and mood controlling for relevant covariates. Standard moderation analyses were performed. RESULTS: Participants reported higher levels of negative and positive mood compared with published means of localized prostate cancer patients. Overall, mood was more positive than negative. Stress levels were comparable to cancer populations with recurrent disease. Moderated regression analyses showed that social support partially buffered the effects of stress on positive mood; men with high stress and low support reported the lowest levels of positive mood. The model with negative mood as the dependent measure did not support moderation; that is, the relationship between stress and negative mood did not differ by level of social support. CONCLUSION: Among individuals living with advanced prostate cancer, social support may be an important factor that sustains positive mood in the presence of stress. Future work should examine the extent to which social support prospectively impacts health-related quality of life by promoting positive mood. Limitations include cross-sectional design, which precludes causal inferences.

RESUMO

Little is known about whether and how stress management skills may improve adjustment for men diagnosed with prostate cancer who opt for active surveillance. This study examined whether two types of perceived stress management skills, specifically the ability to relax and confidence in coping, moderated the relationship between prostate cancer (PC) concerns and psychological distress. Participants were 71 ethnically diverse men in active surveillance. Coping confidence moderated the relationship between PC concerns and intrusive thoughts (p < .01). At low levels of coping confidence, PC concerns was positively related to intrusive thoughts, ß = .95, p < .001, but not when coping confidence was high, ß = .19, p > .05. Coping confidence also moderated the relationship between PC treatment concerns (a subscale of PC concerns) and intrusive thoughts. At low levels of coping confidence, PC treatment concerns was positively associated with intrusive thoughts, ß = .73, p < .001, but not when coping confidence was high, ß = .20, p > .05. Findings underscore the importance of interventions aimed at improving coping in men undergoing active surveillance.
