Race-specific prostate cancer outcomes in a cohort of low and favorable-intermediate risk patients who underwent external beam radiation therapy from 1990 to 2017.

BACKGROUND: Previous research exploring the role of race on prostate cancer (PCa) outcomes has demonstrated greater rates of disease progression and poorer overall survival for African American (AA) compared to Caucasian American (CA) men. The current study examines self-reported race as a predictor of long-term PCa outcomes in patients with low and favorable-intermediate risk disease treated with external beam radiation therapy (EBRT). METHODS: This retrospective cohort study examined patients who were consented to enrollment in the Center for Prostate Disease Research Multicenter National Database between January 01, 1990 and December 31, 2017. Men self-reporting as AA or CA who underwent EBRT for newly diagnosed National Comprehensive Cancer Network-defined low or favorable-intermediate risk PCa were included. Dependent study outcomes included: biochemical recurrence-free survival, (ii) distant metastasis-free survival, and (iii) overall survival. Each outcome was modeled as a time-to-event endpoint using race-stratified Kaplan-Meier estimation curves and multivariable Cox proportional hazards analysis. RESULTS: Of 840 men included in this study, 268 (32%) were AA and 572 (68%) were CA. The frequency of biochemical recurrence, distant metastasis, and deaths from any cause was 151 (18.7%), 29 (3.5%), and 333 (39.6%), respectively. AA men had a significantly younger median age at time of EBRT and slightly higher biopsy Gleason scores. Multivariable Cox proportional hazards analyses demonstrated no racial differences in any of the study endpoints. CONCLUSIONS: These findings reveal no racial disparity in PCa outcomes for AA compared to CA men, in a long-standing, longitudinal cohort of patients with comparable access to cancer care.

Opioid-Limiting Pain Control After Transurethral Resection of the Prostate: A Randomized Controlled Trial.

OBJECTIVE: To assess whether a multimodal opioid-limiting protocol and patient education intervention can reduce postoperative opioid use following transurethral resection of the prostate. METHODS: This prospective, non-blinded, single-institution, randomized controlled trial (NCT04102566) assigned 50 patients undergoing a transurethral resection of the prostate to either a standard of care control (SOC) or multimodal experimental group (MMG). The intervention included adding ibuprofen to the postoperative pain regimen, promoting appropriate opioid use while hospitalized, an educational intervention, and discharging without opioid prescription. Data regarding demographics, operative data, opioid use, pain scores, and patient satisfaction were compared. RESULTS: A total of 47 patients were included, n = 23 (MMG) and n = 24 (SOC). Demographic and operative findings were similar. Statistical analysis for noninferiority demonstrated non-inferior inpatient pain control (mean pain score 2.5 MMG vs 2.4 SOC, P = 0.0003). The multimodal group used significantly fewer morphine milligram equivalents after discharge (0 vs 4.1, P = 0.04). Inpatient use was reduced but did not reach statistical significance (6.0 vs 9.8, P = 0.2). Mean satisfaction scores with pain control were similar (9.6 MMG vs 9.2 SOC, P = 0.32). No opioid prescriptions were requested after discharge. Adverse events and medication side effects were infrequent and largely similar between groups. CONCLUSION: Implementation of an opioid-limiting postoperative pain protocol and patient education resulted in no outpatient opioid use while maintaining patient satisfaction with pain control. Eliminating opioids following a common urologic procedure will decrease risk of opioid-related adverse events and have a positive downstream impact.

Contemporary trends in management of stage 1 seminoma.

PURPOSE: Surveillance is now the preferred treatment strategy for patients with stage 1A/1B seminoma as reflected by the National Comprehensive Cancer Network guidelines. In this study, we aimed to describe trends in adjuvant management strategy for stage 1A/B seminoma from 2004 to 2016 using the National Cancer Database. MATERIALS AND METHODS: The database was queried for patients diagnosed with stage 1A/1B seminoma between 2004 and 2016. Staging was determined using the American Joint Committee on Cancer guidelines. Surveillance was defined as no treatment with chemotherapy or radiation within 60 days of diagnosis. Proportions of cancer patients utilizing surveillance, radiation, and single-agent chemotherapy were summarized annually. Kaplan-Meier survival analysis was used to compare overall survival between groups. RESULTS: 8,686 patients with stage 1A/1B seminoma met inclusion criteria over the course of the study period. Overall, 3,004 (34.6%) patients began adjuvant chemotherapy or radiation within 60 days. Utilization of surveillance increased from 39.8% in 2004 to 86.8% in 2016 while utilization of radiation decreased from 59.7% to 4.6%. High-volume centers adopted surveillance earlier than low-volume centers. CONCLUSION: This study describes trends in utilization of surveillance, chemotherapy, and radiotherapy for stage 1A/1B seminoma over 12 years. A major shift from utilization of adjuvant treatment to surveillance in patients with stage 1A/B seminoma is observed in this large national cancer database; a minority of patients now receive adjuvant treatment and risk-related toxicities. Survival analysis reveals similar survival at a median 5-year follow-up. The results provide insight into the time needed for clinical practice to adopt the preferred approach of surveillance over the time period studied.

A prospective analysis of health-related quality of life in intermediate and high-risk prostate cancer patients managed with intensity modulated radiation therapy, with vs. without hormonal therapy.

INTRODUCTION: Combined radiotherapy and hormonal treatment are recommended for intermediate- and high-risk prostate cancer (CaP). This study compared the long-term effects on health-related quality of life (HRQoL) of intermediate- and high-risk CaP patients managed with radiation therapy (RT) with vs. without hormone therapy (HT). METHODS: Patients with intermediate- and high-risk CaP enrolled in the Center for Prostate Disease Research diagnosed from 2007 to 2017 were included. EPIC and SF-36 questionnaires were completed and HRQoL scores were compared for patients receiving RT vs. RT + HT at baseline (pretreatment), 6, 12, 24, 36, 48, and 60 months after CaP diagnosis. Longitudinal patterns of change in HRQoL were modeled using linear regression models, adjusting for baseline HRQoL, age at CaP diagnosis, race, comorbidities, National Comprehensive Cancer Network (NCCN) risk stratum, time to treatment, and follow-up time. RESULTS: Of 164 patients, 93 (56.7%) received RT alone and 71 (43.3%) received RT + HT. Both groups reported comparable baseline HRQoL. Patients receiving RT+HT were more likely to be NCCN high risk as compared to those receiving only RT. The RT + HT patients experienced worse sexual function, hormonal function, and hormonal bother than those who only received RT; however, HRQoL recovered over time for the RT + HT group. No significant differences were observed between groups in urinary and bowel domains or SF-36 mental and physical scores. CONCLUSION: Combined RT + HT treatment was associated with temporary lower scores in sexual and hormonal HRQoL compared with RT only. Intermediate- and high-risk CaP patients should be counseled about the possible declines in HRQoL associated with HT.

Utilization of retroperitoneal lymph node dissection for testicular cancer in the United States: Results from the National Cancer Database (1998-2011).

INTRODUCTION: Retroperitoneal lymph node dissection (RPLND) for the treatment of testicular cancer is a relatively rare and complex operation that may contribute to differences in utilization. We sought to characterize the use of RPLND between different categories of cancer center facilities in the United States. MATERIALS AND METHODS: The National Cancer Database was queried for patients with germ cell tumors treated at different types of cancer centers between 1998 and 2011. The proportion of patients who underwent RPLND was stratified by stage and histology and then compared between treatment facilities. RPLND utilization was then compared between facility types as a function of time. RESULTS: A total of 59,652 patients met inclusion criteria and 5,475 (9.2%) underwent RPLND. The proportion of patients treated with RPLND for non-seminomatous germ cell tumor (NSGCT) was significantly different between cancer center types for all stages (P<0.001) and used most often in academic comprehensive cancer centers. There was no difference in the proportion of RPLND utilization for stage II and III seminoma stratified by treatment facility. There was a significantly decreased trend in the utilization of RPLND for stage I (P = 0.032) NSGCT whereas utilization was increased for stage III NSGCT (P≤0.001) over the study period. CONCLUSIONS: The proportion of patients undergoing RPLND for NSGCT varies significantly by the type of cancer center and is used most often in academic cancer centers. Utilization of RPLND decreased for stage I NSGCT and increased for stage III NSGCTs during the study period.

Does a perioperative belladonna and opium suppository improve postoperative pain following robotic assisted laparoscopic radical prostatectomy? Results of a single institution randomized study.

INTRODUCTION: Robotic assisted laparoscopic radical prostatectomy (RALP) is a common treatment for localized prostate cancer. Despite a primary advantage of improved postoperative pain, patients undergoing RALP still experience discomfort. Belladonna, containing the muscarinic receptor antagonists atropine and scopolamine, in combination with opium as a rectal suppository (B & O) may improve post-RALP pain. This study evaluates whether a single preoperative B & O results in decreased postoperative patient-reported pain and analgesic requirements. MATERIALS AND METHODS: Patients undergoing RALP at Virginia Mason Medical Center between November 2008 and July 2009 were offered the opportunity to enter a randomized, double-blind, placebo-controlled trial. Exclusion criteria included: glaucoma, bronchial asthma, convulsive disorders, chronic pain, chronic use of analgesics, or a history of alcohol or opioid dependency. Surgeons were blinded to suppository placement which was administered after induction of anesthesia. All patients underwent a standardized anesthesia regimen. Postoperative pain was assessed by a visual analog scale (VAS) and postoperative narcotic use was calculated in intravenous morphine equivalents. RESULTS: Ninety-nine patients were included in the analysis. The B & O and control groups were not significantly different in terms of age, body mass index, operative time, nerve sparing status or prostatic volume. Postoperative pain was significantly improved during the first two postoperative hours in the B & O group. Similarly, 24-hour morphine consumption was significantly lower in patients who received a B & O. No adverse effects secondary to suppository placement were identified. CONCLUSION: Preoperative administration of B & O suppository results in significantly decreased postoperative pain and 24-hour morphine consumption in patients undergoing RALP.
