Contemporary prostate cancer treatment choices in multidisciplinary clinics referenced to national trends.

BACKGROUND: The purpose of this study was to assess treatment choices among men with prostate cancer who presented at The University of Texas MD Anderson Cancer Center multidisciplinary (MultiD) clinic compared with nationwide trends. METHODS: In total, 4451 men with prostate cancer who presented at the MultiD clinic from 2004 to 2016 were analyzed. To assess nationwide trends, the authors analyzed 392,710 men with prostate cancer who were diagnosed between 2004 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) database. The primary endpoint was treatment choice as a function of pretreatment demographics. RESULTS: Univariate analyses revealed similar treatment trends in the MultiD and SEER cohorts. The use of procedural forms of definitive therapy decreased with age, including brachytherapy and prostatectomy (all P < .05). Later year of diagnosis/clinic visit was associated with decreased use of definitive treatments, whereas higher risk grouping was associated with increased use (all P < .001). Patients with low-risk disease treated at the MultiD clinic were more likely to receive nondefinitive therapy than patients in SEER, whereas the opposite trend was observed for patients with high-risk disease, with a substantial portion of high-risk patients in SEER not receiving definitive therapy. In the MultiD clinic, African American men with intermediate-risk and high-risk disease were more likely to receive definitive therapy than white men, but for SEER the opposite was true. CONCLUSIONS: Presentation at a MultiD clinic facilitates the appropriate disposition of patients with low-risk disease to nondefinitive strategies of patients with high-risk disease to definitive treatment, and it may obviate the influence of race.

Radical prostatectomy or radiotherapy for high- and very high-risk prostate cancer: a multidisciplinary prostate cancer clinic experience of patients eligible for either treatment.

OBJECTIVE: To compare radical prostatectomy (RP) vs radiotherapy (RT) with androgen-deprivation therapy (ADT) in the setting of patients with high-risk and very high-risk (VHR) prostate cancer who were deemed eligible for either therapy and made a treatment choice after consultation in a multidisciplinary prostate cancer clinic (MDPCC), and to compare the MDPCC patients' outcomes to a matched Surveillance, Epidemiology and End Results (SEER) cohort. PATIENTS AND METHODS: Prospectively collected, retrospective study comparing patients who underwent RP (231 patients) vs RT+ADT (73) from 2004 to 2013. Biochemical recurrence (BCR), local recurrence, distant metastasis failure, and overall survival (OS) were calculated for each treatment group overall and according to National Comprehensive Cancer Network risk strata. A propensity score matched comparison with a SEER cohort was performed for OS. RESULTS: There was no difference in local recurrence (hazard ratio [HR] 2.7, 95% confidence interval [CI] 1.0-7.9; P = 0.06), distant metastasis failure (HR 2.5, 95% CI 0.8-7.8; P = 0.1) and OS (HR 1.35, 95% CI 0.4-4.8; P = 0.6) between patients undergoing RP vs RT+ADT. Patients treated via the MDPCC survived on average 16.9 months (95% CI 13.1-20.8) longer than those in the matched SEER cohort. CONCLUSIONS: Long-term outcomes appear similar amongst patients with high-risk and VHR prostate cancer deemed eligible for either RP or RT, and treated after consultation in a MDPCC. Outcomes of the MDPCC patients were superior to those of the matched SEER cohort.

Quality of life after brachytherapy or bilateral nerve-sparing robot-assisted radical prostatectomy for prostate cancer: a prospective cohort.

OBJECTIVE: To provide comparative data on quality of life (QoL) after prostate cancer treatment to help patients make an informed decision regarding their choice of treatment. METHODS: Patients with pathologically proven, non-metastatic, T1-T3bN0 prostate cancer were included in this prospective non-randomized study if they were to receive treatment with curative intent. Sample size was at least 181 patients per cohort/treatment type. QoL was recorded at baseline and at each follow-up using the Expanded Prostate Cancer Index Composite (EPIC) instrument. The minimal clinically important difference was defined as half of the standard deviation of the baseline score for each domain. A mixed effects model was used to compare the different treatments. Data are presented on the brachytherapy and the bilateral nerve-sparing robot-assisted radical prostatectomy (RARP) cohorts. Hormonotherapy was not allowed. RESULTS: Between November 2007 and January 2013, 181 patients who received brachytherapy and 210 patients who underwent RARP were included. Of the patients who underwent RARP, 178 had bilateral nerve-sparing and were included in the present analysis. Response rate to EPIC questionnaires were higher in the brachytherapy than in the RARP arm: 82% vs 57% at 2 years after treatment and 55% vs 45% at 4 years after treatment. In the mixed effects model, patients in the RARP arm had better QoL with regard to urinary irritation/obstruction or bother and bowel function, and lower QoL regarding sexual function and urinary incontinence. Results were confirmed in a propensity score-matched model. Patient satisfaction was significantly higher in the brachytherapy group at 1, 2 and 3 years after treatment. CONCLUSION: This prospective non-randomized study shows long-term differences in QoL domains after bilateral nerve-sparing RARP and brachytherapy. Differences in patient satisfaction should be further explored. These results could be used to counsel patients in the decision-making process.

Genitourinary and gastrointestinal toxicity among patients with localized prostate cancer treated with conventional versus moderately hypofractionated radiation therapy: systematic review and meta-analysis.

BACKGROUND: Hypofractionated (HRT) prostate radiation therapy has the potential to deliver a higher biologically effective dose over a shorter time compared with conventional fractionation (CRT). HRT, giving fewer fractions each with higher dose, might improve the therapeutic ratio, resource use and patient convenience but the toxicity is still controversial. Our objective was to compare the gastroinstestinal (GI) and genitourinary (GU) toxicity of HRT versus CRT. METHODS: Systematic review and meta-analysis of randomized clinical trials studies in PubMed, Cochrane and EMBASE databases published through December 2016 was done. Only randomized trials that evaluated patients with localized prostate cancer (PCa) undergoing CRT or HRT were included. In these studies, the daily dose was 1.8 Gy or 2 Gy per day for CRT and 2.4 to 3.4 Gy for HRT. RESULTS: 7317 patients in nine studies were analyzed. Six studies included acute GU toxicity data which showed similar rates for both HRT and CRT (32.6vs. 31.9%; RD 0.00; 95% CI; -0.03,0.03; p = .81; I2 = 0%). Similarly, seven studies showed no difference in late GU toxicity based on treatment schedule (28.7 vs. 28.0%; RD -0.01; 95% CI; -0.04,0.03; p = .67; I2 = 52%). GI toxicity at three months after radiotherapy was higher in patients treated with HRT in six studies (27.5 vs. 21.9%; RD 0.06; 95% CI; 0.02,0.10; p = .004; I2 = 39%); however, eight studies showed GI toxicity 12 months or more after radiotherapy that was statistically the same (12.9 HRT vs. 16.2% CRT; RD -0.01; 95% CI; -0.04,0.02; p = .41; I2 = 58%). CONCLUSION: In meta-analysis of the available randomized trials on moderate HRT versus CRT for prostate cancer, acute and late GU toxicity were similar for both treatment schemes. While HRT was associated with higher acute GI toxicity, late toxicity was similar.

A Double-Blind, Randomized, Placebo-Controlled Trial of Panax Ginseng for Cancer-Related Fatigue in Patients With Advanced Cancer.

Background: Despite the high frequency, severity, and effects of cancer-related fatigue (CRF) on the quality of life (QoL) of patients with cancer, limited treatment options are available. The primary objective of this study was to compare the effects of oral Panax ginseng extract (PG) and placebo on CRF. Secondary objectives were to determine the effects of PG on QoL, mood, and function. Methods: In this randomized, double-blind, placebo-controlled study, patients with CRF ≥4/10 on the Edmonton Symptom Assessment System (ESAS) were eligible. Based on a pilot study, we randomized patients to receive either 400 mg of standardized PG twice daily or a matching placebo for 28 days. The primary end point was change in the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) subscale from baseline to day 29. Results: Of 127 patients, 112 (88.2%) were evaluable. The mean (SD) FACIT-F subscale scores at baseline, day 15, and day 29 were 22.4 (10.1), 29.9 (10.6), and 30.1 (11.6) for PG (P<.001), and 24.0 (9.4), 30.0 (10.1), and 30.4 (11.5) for placebo (P<.001). Mean (SD) improvement in the FACIT-F subscale at day 29 was not significantly different in the PG than in the placebo group (7.5 [12.7] vs 6.5 [9.9]; P=.67). QoL, anxiety, depression, symptoms, and functional scores were not significantly different between the PG and placebo groups. Improvement in the FACIT-F subscale correlated with baseline scores (P=.0005), Hospital Anxiety and Depression Scale results (P=.032), and sex (P=.023). There were fewer any-grade toxicities in the PG versus placebo group (28/63 vs 33/64; P=.024). Conclusions: Both PG and placebo result in significant improvement in CRF. PG was not significantly superior to placebo after 4 weeks of treatment. There is no justification to recommend the use of PG for CRF. Further studies are needed. Trial Registration: ClinicalTrials.gov identifier: NCT01375114.

The role of androgen deprivation therapy on biochemical failure and distant metastasis in intermediate-risk prostate cancer: effects of radiation dose escalation.

BACKGROUND: To determine whether the effect of androgen deprivation therapy (ADT) on the risk of biochemical failure varies at different doses of radiation in patients treated with definitive external beam radiation for intermediate risk prostate cancer (IRPC). METHODS: This study included 1218 IRPC patients treated with definitive external beam radiation therapy to the prostate and seminal vesicles from June 1987 to January 2009 at our institution. Patient, treatment, and tumor information was collected, including age, race, Gleason score, radiation dose, PSA, T-stage, and months on ADT. RESULTS: The median follow-up was 6 years. A total of 421(34.6%) patients received ADT, 211 (17.3%) patients experienced a biochemical failure, and 38 (3.1%) developed distant metastasis. On univariable analyses, higher PSA, earlier year of diagnosis, higher T-stage, lower doses of radiation, and the lack of ADT were associated with an increased risk of biochemical failure. No difference in biochemical failure was seen among different racial groups or with the use of greater than 6 months of ADT compared with less than 6 months. On multivariate analysis, the use of ADT was associated with a lower risk of biochemical failure than no ADT (HR, 0.599; 95% CI, 0.367-0.978; P<0.04) and lower risk of distant metastasis (HR, 0.114; 95% CI, 0.014-0.905; P=0.04). CONCLUSIONS: ADT reduced the risk of biochemical failure and distant metastasis in both low- and high dose radiation groups among men with intermediate-risk PCa. Increasing the duration of ADT beyond 6 months did not reduce the risk of biochemical failures. Better understanding the benefit of ADT in the era of dose escalation will require a randomized clinical trial.

Current clinical presentation and treatment of localized prostate cancer in the United States.

PURPOSE: SEER recently released patient Gleason scores at biopsy/transurethral resection of the prostate. For the first time this permits accurate assessment of prostate cancer presentation and treatment according to clinical factors at diagnosis. MATERIALS AND METHODS: We used the SEER database to identify men diagnosed with localized prostate cancer in 2010 who were assigned NCCN(®) risk based on clinical factors. We identified sociodemographic factors associated with high risk disease and analyzed the impact of these factors along with NCCN risk on local treatment. RESULTS: Of the 42,403 men identified disease was high, intermediate and low risk in 38%, 40% and 22%, respectively. On multivariate analysis patients who were older, nonwhite, unmarried or living in a county with a higher poverty rate were more likely to be diagnosed with high risk disease (each p <0.05). Of the 38,634 men in whom prostate cancer was the first malignancy 23% underwent no local treatment, 40% were treated with prostatectomy, 36% received radiation therapy and 1% underwent local tumor destruction, predominantly cryotherapy. On multivariate analysis patients who were older, black, unmarried or living in a county with a higher poverty rate, or who had low risk disease were less likely to receive local treatment (each p <0.05). CONCLUSIONS: Our analysis provides information on the current clinical presentation and treatment of localized prostate cancer in the United States. Nonwhite and older men living in a county with a higher poverty rate were more likely to be diagnosed with high risk disease and less likely to receive local treatment.

Impact of a clinical trial initiative on clinical trial enrollment in a multidisciplinary prostate cancer clinic.

Clinical oncology trials are hampered by low accrual rates, with fewer than 5% of adult patients with cancer treated on study. Clinical trial enrollment was evaluated at The University of Texas MD Anderson Cancer Center's Multidisciplinary Prostate Cancer Clinic (MPCC) to assess whether a clinical trial initiative, introduced in 2006, impacted enrollment. The trial initiative included posting trial-specific information in clinic, educating patients about appropriate clinical trial options during the treatment recommendation discussion, and providing patients with trial-specific educational information. The investigators evaluated the frequency of clinical trial enrollment for men with newly diagnosed prostate cancer seen in the MPCC from 2004 to 2008. Logistic regression evaluated the impact of patient characteristics and the clinical trial initiative on trial enrollment. The median age of the 1370 men was 64 years; 32% had low-risk, 49% had intermediate-risk, and 19% had high-risk disease. Overall, 74% enrolled in at least one trial and 29% enrolled in more than one trial. Trial enrollment increased from 39% before the initiative (127/326) to 84% (880/1044) after the trial initiative. Patient enrollment increased in laboratory studies (from 25% to 80%), quality-of-life studies (from 10% to 26%), and studies evaluating investigational treatments and systemic agents (from 6% to 15%) after the trial initiative. In multivariate analysis, younger men (P<.001) and men seen after implementation of the clinical trial initiative (P<.001) were more likely to enroll in trials. Clinical trial enrollment in the MPCC was substantially higher than that seen nationally in adult patients with cancer, and enrollment rates increased after the introduction of a clinical trial initiative.

'It's not like you just had a heart attack': decision-making about active surveillance by men with localized prostate cancer.

BACKGROUND: Growing recognition that active surveillance (AS) is a reasonable management option for many men diagnosed with localized prostate cancer led us to describe patients' conceptualizations of AS and reasons for their treatment decisions. METHODS: Men were patients of a multidisciplinary prostate cancer clinic at a large tertiary cancer center where patients are routinely briefed on treatment options, including AS. We conducted a thematic analysis of interviews with 15 men who had chosen AS and 15 men who received radiation or surgery. RESULTS: Men who chose AS described it as an organized process with a rigorous and reassuring protocol of periodic testing, with potential for subsequent and timely decision-making about treatment. AS was seen as prolonging their current good health and function with treatment still possible later. Rationales for choosing AS included trusting their physician's monitoring, 'buying time' without experiencing adverse effects of treatment, waiting for better treatments, and seeing their cancer as very low risk. Men recognized the need to justify their choice to others because it seemed contrary to the impulse to immediately treat cancer. Descriptions of AS by men who chose surgery or radiation were less specific about the testing regimen. Getting rid of the cancer and having a cure were paramount for them. CONCLUSIONS: Men fully informed of their treatment options for localized prostate cancer have a comprehensive understanding of the purpose of AS. Slowing the decision-making process may enhance the acceptability of AS.

Implementation and Efficacy of a Large-Scale Radiation Oncology Case-Based Peer-Review Quality Program across a Multinational Cancer Network.

PURPOSE: With expansion of academic cancer center networks across geographically-dispersed sites, ensuring high-quality delivery of care across all network affiliates is essential. We report on the characteristics and efficacy of a radiation oncology peer-review quality assurance (QA) system implemented across a large-scale multinational cancer network. METHODS AND MATERIALS: Since 2014, weekly case-based peer-review QA meetings have been standard for network radiation oncologists with radiation oncology faculty at a major academic center. This radiotherapy (RT) QA program involves pre-treatment peer-review of cases by disease site, with disease-site subspecialized main campus faculty members. This virtual QA platform involves direct review of the proposed RT plan as well as supporting data, including relevant pathology and imaging studies for each patient. Network RT plans were scored as being concordant or nonconcordant based on national guidelines, institutional recommendations, and/or expert judgment when considering individual patient-specific factors for a given case. Data from January 1, 2014, through December 31, 2019, were aggregated for analysis. RESULTS: Between 2014 and 2019, across 8 network centers, a total of 16,601 RT plans underwent peer-review. The network-based peer-review case volume increased over the study period, from 958 cases in 2014 to 4,487 in 2019. A combined global nonconcordance rate of 4.5% was noted, with the highest nonconcordance rates among head-and-neck cases (11.0%). For centers that joined the network during the study period, we observed a significant decrease in the nonconcordance rate over time (3.1% average annual decrease in nonconcordance, P = 0.01); among centers that joined the network prior to the study period, nonconcordance rates remained stable over time. CONCLUSIONS: Through a standardized QA platform, network-based multinational peer-review of RT plans can be achieved. Improved concordance rates among newly added network affiliates over time are noted, suggesting a positive impact of network membership on the quality of delivered cancer care.

Long-term outcomes for men with high-risk prostate cancer treated definitively with external beam radiotherapy with or without androgen deprivation.

BACKGROUND: Men with high-risk prostate cancer are often thought to have very poor outcomes in terms of disease control and survival even after definitive treatment. However, results after external beam radiotherapy have improved significantly through dose escalation and the use of androgen deprivation therapy (ADT). This report describes long-term findings after low-dose (< 75.6 Gy) or high-dose (≥ 75.6 Gy) external beam radiation, with or without ADT. METHODS: This analysis included 741 men with high-risk prostate cancer (clinical classification ≥ T3, Gleason score ≥ 8, or prostate-specific antigen level ≥ 20 ng/mL) treated with external beam radiotherapy at a single tertiary institution from 1987 through 2004. The radiation dose ranged from 60 to 79.3 Gy (median, 70 Gy); 295 men had received ADT for ≥ 2 years, and the median follow-up time was 8.3 years. RESULTS: The 5- and 10-year actuarial overall survival rates were significantly better for men treated with the higher radiation dose (no ADT plus ≥ 75.6 Gy, 87.3% and 72.0%, respectively; and ADT plus ≥ 75.6 Gy, 92.3% and 72%, respectively) (P = .0035). The corresponding 5- and 10-year biochemical failure-free survival rates were significantly better for patients treated with both ADT and higher radiation dose (82% and 77%, P < .0001). At 5 years, men who had not received ADT and had received radiation dose < 75.6 Gy had higher clinical local failure rates than those given ADT and radiation dose ≥ 75.6 Gy (24.2% versus 0%, P < .0001). The 10-year symptomatic local failure rate was only 2% for all patients. CONCLUSIONS: Contrary to lingering historical perceptions, treatment of high-risk prostate cancer with modern, high-dose, external beam radiotherapy and ADT can produce better biochemical, clinical, and survival outcomes over those from previous eras. Specifically, symptomatic local failure is uncommon, and few men die of prostate cancer even 10 or more years after treatment.

Outcomes in stage I testicular seminoma: a population-based study of 9193 patients.

BACKGROUND: Few studies have quantified temporal patterns of cause-specific mortality in contemporary cohorts of men with early-stage seminoma. Given that several management strategies can be applied in these patients, each resulting in excellent long-term survival, it is important to evaluate associated long-term sequelae. In particular, data describing long-term risks of cardiovascular disease (CVD) are conflicting. METHODS: We identified 9193 men diagnosed with stage I seminoma (ages 15-70 years) in the population-based SEER registries (1973-2001). We calculated survival estimates, standardized mortality ratios (SMRs), and adjusted hazard rates (AHRs). RESULTS: During 121,037 person-years of follow-up (median, 12.3 years), 915 deaths (SMR, 1.23; 95% CI, 1.16-1.32) were reported, with significant excesses for suicide (n = 39; SMR, 1.45; 95% CI, 1.06-1.98), infection (n = 58; SMR, 2.32; 95% CI, 1.80-3.00), and second malignant neoplasms (SMNs; n = 291; SMR, 1.81; 95% CI, 1.61-2.03), but not CVD (n = 201; SMR, 0.91; 95% CI, 0.80-1.05). After radiotherapy (78% patients), CVD deaths were not increased (n = 158; SMR, 0.89; 95% CI, 0.76-1.04), in contrast to SMN deaths (n = 246; SMR, 1.89; 95% CI, 1.67-2.14). SMN mortality was higher among patients administered radiotherapy than among those not given radiotherapy (AHR, 1.36; 95% CI, 0.99-1.88; P = .059), with a cumulative 15-year risk of 2.64% (95% CI, 2.19-3.16). Suicide, although rare, accounted for 1 in 230 deaths. CONCLUSIONS: Modern radiotherapy as applied in this large population-based study is not associated with excess CVD mortality. Although increased all-cause mortality exists, cumulative SMN risk is considerably smaller than reported in historical series, but additional follow-up will be required to characterize long-term trends. The increased risk of suicide, previously unreported in men with stage I seminoma, requires confirmation.

Penile cancer: Clinical Practice Guidelines in Oncology.

Squamous cell carcinoma of the penis represents approximately 0.5% of all cancers among men in the United States and other developed countries. Although rare, it is associated with significant disfigurement, and only half of the patients survive beyond 5 years. Proper evaluation of both the primary lesion and lymph nodes is critical, because nodal involvement is the most important factor of survival. The NCCN Clinical Practice Guidelines in Oncology for Penile Cancer provide recommendations on the diagnosis and management of this devastating disease based on evidence and expert consensus.

Bladder cancer.

Bladder cancer is the fourth most common cancer in the United States. Urothelial carcinoma that originates from the urinary bladder is the most common subtype. These NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) provide recommendations on the diagnosis and management of non-muscle-invasive and muscle-invasive urothelial carcinoma of the bladder. This version of the guidelines provides extensive reorganization and updates on the principles of chemotherapy management.

Use of maximum slope images generated from dynamic contrast-enhanced MRI to detect locally recurrent prostate carcinoma after prostatectomy: a practical approach.

OBJECTIVE: The purpose of this article is to present the value of high-temporal-resolution and high-spatial-resolution dynamic contrast-enhanced MRI (DCE-MRI) combined with the postprocessed slope images generated from the fastest rate of enhancement of each voxel for detecting local recurrence of prostate carcinoma after radical prostatectomy. METHODS AND MATERIALS: Of 125 patients, 47 patients with and without local recurrence confirmed by biopsy or clinical follow-up were identified. All patients underwent DCE-MRI with a spatial resolution of 3 mm and mean temporal resolution of 11.3 seconds (range, 8.4-14.0 seconds). RESULTS: In patients with local recurrence, the mean (± SD) prostate-specific antigen level and tumor size were 1.9 ± 1.8 mg/dL and 10.8 ± 5.7 mm, respectively, at the time of MRI. Thirty-six of 37 patients (97%) with biopsy or clinically confirmed local recurrence had positive MRI findings. Eight of 10 patients (80%) with negative recurrence had negative MRI findings. Of the 36 patients, 16 (44%) had time-intensity curves of rapid increase-rapid washout and 18 (50%) had rapid increase-plateau or slow washout. The recurrent tumor reached the peak enhancement within one phase following the peak enhancement of the common femoral artery. In patients with a negative MRI result, the mean PSA level was 0.2 ± 0.1 mg/dL. CONCLUSION: DCE-MRI using high temporal and spatial resolution is highly accurate in detecting subcentimeter local recurrences within the postprostatectomy bed. Combined with visual inspection of original source images (using the common femoral artery as a reference), the slope image is a simple and practical way of identifying locally recurrent prostate carcinoma.

Patients' Preferences for Androgen Deprivation Therapy in the Treatment of Intermediate-Risk Prostate Cancer.

Background. For men with intermediate-risk prostate cancer (IRPC), adding short-term androgen deprivation therapy (ADT) to external beam radiation therapy (EBRT) has shown efficacy, but men are often reluctant to accept it because of its impact on quality of life. Methods. We conducted time tradeoffs (score of 1 = perfect health and 0 = death) and probability tradeoffs with patients aged 51 to 78 y who had received EBRT for IRPC within the past 2 y. Of 40 patients, 20 had received 6 mo of ADT and 20 had declined. Utility assessments explored 4 ADT-related side effects: hot flashes, fatigue, loss of libido/erectile dysfunction, and weight gain. Results. The most commonly reported "worst" treatment-related complication of ADT was fatigue (50% in both cohorts) followed by reduced libido/erectile dysfunction (40% in both cohorts). The utilities for fatigue were mean = 0.71 and median = 0.92 and for reduced libido/erectile dysfunction were mean = 0.81 and median = 0.92. Utilities did not differ significantly between cohorts. Assuming a 6-mo course of ADT, men reported being willing to trade 3 mo of life expectancy to avoid fatigue due to ADT and 1.8 mo to avoid sexual side effects. Patients in the ADT cohort were willing to accept the side effects of ADT in exchange for a mean 8% absolute increase in survival, whereas patients in the no ADT cohort required a 16% increase (P < 0.001). Conclusions. When considering treatment with ADT, men with IRPC identified fatigue and sexual dysfunction as the most bothersome side effects. Patients who declined ADT expected a larger survival benefit than those who opted for treatment. Both groups expected a survival benefit exceeding that shown by recent trials, suggesting some men may be selecting treatments inconsistent with their preferences. Highlights: This study demonstrates that prostate cancer patients receiving radiation therapy are reluctant to receive androgen deprivation therapy (ADT) most commonly due to anticipated fatigue and loss of libido/erectile dysfunction.Men who had received ADT reported they would require an average 8% absolute increase in survival to tolerate its side effects, whereas those who declined ADT would require an average 16% increase.Required thresholds are well above the estimated absolute survival benefit for ADT demonstrated in recent clinical trials, suggesting an unmet need for improved patient education regarding the risks and benefits of ADT.

Improving efficiency and reducing costs of MRI-Guided prostate brachytherapy using Time-Driven Activity-Based costing.

INTRODUCTION: Integrated quality improvement (QI) and cost reduction strategies can help increase value in cancer care. Time-driven activity-based costing (TDABC) is a bottom-up costing tool that measures resource use over the full care cycle. We applied standard QI and TDABC methods to improve workflow efficiency and reduce costs for MRI-guided prostate brachytherapy. METHODS AND MATERIALS: We constructed process maps of the baseline prostate brachytherapy workflow from initial consultation through one year after treatment. Process maps reflected resources and time required at each step. TDABC costs were calculated by multiplying each process time by the cost per min of the resource(s) used at that step. We then used plan-do-study-act methodology to identify workflow inefficiencies and implement solutions to reduce resource consumption. RESULTS: The highest cost components at baseline were the operating room (OR) (40%), imaging (8.7%), and consultation (7.6%). Higher-than-expected costs (3%) were incurred during surgery scheduling. After targeted QI initiatives, OR time was reduced from 90 to 70 min, which reduced overall cost by 5%. Personnel task downshifting reduced costs by 10% at consultation and 77% at surgery scheduling. Re-engineering of follow-up protocols reduced costs by 8.4%. Costs under the new workflow decreased by 18.2%. CONCLUSIONS: TDABC complements traditional QI initiatives by quantifying the highest cost steps and focusing QI initiatives to reduce costs and improve efficiency. As payment reform evolves toward bundled payments, TDABC and QI initiatives will help providers understand, communicate, and improve the value of cancer care.

Recommendations for post-prostatectomy radiation therapy in the United States before and after the presentation of randomized trials.

PURPOSE: The EORTC 22911 and the SWOG 8794 studies, presented in 2004 and 2005, showed that adjuvant radiation therapy after prostatectomy improved biochemical disease-free survival in men with adverse pathological features. In this study we evaluated the use of post-prostatectomy radiation therapy following the presentation of these results, and the impact of margin involvement, pathological tumor stage, Gleason score and sociodemographic factors on post-prostatectomy radiation therapy recommendations. MATERIALS AND METHODS: The SEER cancer registry was used to identify 21,917 men who underwent radical prostatectomy for N0M0 prostate cancer with adverse pathological features (pT3 or margin positive pT2 disease) from 2000 through 2007. RESULTS: After adjusting for age, diagnosis year, race, SEER region and county education level in a multivariable regression model, decreasing age, margin involvement and Gleason 8 to 10 cancer were associated with receiving post-prostatectomy radiation therapy (all p < 0.001). Men with pT3a (AOR 2.95, CI 2.64-3.29) and pT3b disease (AOR 6.77, CI 5.75-7.97) were more likely to receive post-prostatectomy radiation therapy than those with pT2 disease. The use of post-prostatectomy radiation therapy did not increase after the presentation of study results (p = 0.166). CONCLUSIONS: While men with involved margins and more aggressive pathological disease features were more likely to receive post-prostatectomy radiation therapy, recommendations for post-prostatectomy radiation did not increase after the initial reports from the randomized trials, perhaps because these studies initially reported improved biochemical disease-free survival but not overall survival. Whether the recent report of a survival benefit from adjuvant radiation therapy in the SWOG trial will impact patterns of care requires further followup.

Prediction of erectile function following treatment for prostate cancer.

CONTEXT: Sexual function is the health-related quality of life (HRQOL) domain most commonly impaired after prostate cancer treatment; however, validated tools to enable personalized prediction of erectile dysfunction after prostate cancer treatment are lacking. OBJECTIVE: To predict long-term erectile function following prostate cancer treatment based on individual patient and treatment characteristics. DESIGN: Pretreatment patient characteristics, sexual HRQOL, and treatment details measured in a longitudinal academic multicenter cohort (Prostate Cancer Outcomes and Satisfaction With Treatment Quality Assessment; enrolled from 2003 through 2006), were used to develop models predicting erectile function 2 years after treatment. A community-based cohort (community-based Cancer of the Prostate Strategic Urologic Research Endeavor [CaPSURE]; enrolled 1995 through 2007) externally validated model performance. Patients in US academic and community-based practices whose HRQOL was measured pretreatment (N = 1201) underwent follow-up after prostatectomy, external radiotherapy, or brachytherapy for prostate cancer. Sexual outcomes among men completing 2 years' follow-up (n = 1027) were used to develop models predicting erectile function that were externally validated among 1913 patients in a community-based cohort. MAIN OUTCOME MEASURES: Patient-reported functional erections suitable for intercourse 2 years following prostate cancer treatment. RESULTS: Two years after prostate cancer treatment, 368 (37% [95% CI, 34%-40%]) of all patients and 335 (48% [95% CI, 45%-52%]) of those with functional erections prior to treatment reported functional erections; 531 (53% [95% CI, 50%-56%]) of patients without penile prostheses reported use of medications or other devices for erectile dysfunction. Pretreatment sexual HRQOL score, age, serum prostate-specific antigen level, race/ethnicity, body mass index, and intended treatment details were associated with functional erections 2 years after treatment. Multivariable logistic regression models predicting erectile function estimated 2-year function probabilities from as low as 10% or less to as high as 70% or greater depending on the individual's pretreatment patient characteristics and treatment details. The models performed well in predicting erections in external validation among CaPSURE cohort patients (areas under the receiver operating characteristic curve, 0.77 [95% CI, 0.74-0.80] for prostatectomy; 0.87 [95% CI, 0.80-0.94] for external radiotherapy; and 0.90 [95% CI, 0.85-0.95] for brachytherapy). CONCLUSION: Stratification by pretreatment patient characteristics and treatment details enables prediction of erectile function 2 years after prostatectomy, external radiotherapy, or brachytherapy for prostate cancer.

COVID-19 and Oncology: Operationalizing Best Practices Across Collaborative Health Systems.

To plan for a proactive approach to support patients traveling for their treatment during the COVID-19 pandemic, a network of oncology hospitals worked within existing collaborative agreements to define policies and procedures to transition care for patients living in communities in close proximity to a member institution. Nurse leaders were instrumental in collaborating with and leading interprofessional partners to achieve these outcomes. These efforts led to patients' abilities to continue treatment in their local community, ensuring continuity of cancer care.
