A prospective evaluation of patient perspectives and financial considerations during prostate cancer treatment decision-making.

INTRODUCTION: In universal healthcare systems, patients may still encounter financial obstacles from cancer treatments, potentially influencing treatment decision-making. We investigated the relationship between socioeconomic status and treatment decision-making as it pertains to patient values, preferences, and perceived barriers to care for localized prostate cancer. METHODS: We conducted a prospective study of patients undergoing a prostate biopsy for the initial detection of prostate cancer. Sociodemographic variables were collected, with validated instruments used to determine health literacy levels. Patients were divided into two groups using self-reported income; those with a positive identification of prostate cancer underwent additional surveys to ascertain their knowledge of their diagnosis, treatment-related preferences, and socioeconomic barriers to care. Descriptive statistics were used. RESULTS: Of 160 patients, approximately one-third were classified as having low health literacy. Within the low-income group, education levels were lower (34.6% had less than high school education vs. 10.2% in the high-income group) and unemployment rates higher (75.0% unemployed vs. 38.9% in the high-income group). Low-income patients with prostate cancer placed greater importance on indirect out-of-pocket expenses related to treatment (78.3% vs. 33.3%, p=0.001), higher emphasis on treatment-related travel time (50% vs. 15.1%, p=0.004), and more often had difficulty paying for healthcare services in the past (30.9% vs. 9.1%, p=0.02). CONCLUSIONS: Patients with lower household incomes have unique treatment values and decision-making preferences. They may experience additional challenges and barriers to obtaining cancer care, at least partly related to indirect costs. These findings should be considered when framing prostate cancer treatment discussions and designing patient-facing health information.

Chronic kidney damage pathology score for systematic assessment of the non-neoplastic kidney tissue and prediction of post-operative renal function outcomes.

To establish a systematic histological assessment of non-neoplastic kidney (NNK) tissue at the time of nephrectomy to evaluate a patient's risk of developing post-operative renal dysfunction, a combined prospective pathologic assessment of the NNK and a retrospective clinical chart review was conducted. A blinded nephropathologist performed standardized assessment of glomerular sclerosis, tubulointerstitial fibrosis, arteriosclerosis, and hyaline arteriolosclerosis. Combined these formulated the chronic kidney damage pathology score (CKDPS). Multivariate logistic regression models were developed to assess the effect of CKDPS and other clinical factors on renal function up to 24 months following nephrectomy (partial or radical). 156 patients were included in the analysis with a median age of 60 years. 70% patients underwent radical nephrectomy. A history of hypertension and/or diabetes was present in 55.8% and 22.1%, respectively. Higher CKDPS (particularly glomerular global sclerosis and arteriosclerosis scores), radical nephrectomy, and reduced baseline estimated glomerular filtration rate (eGFR) were associated with worsening post-operative renal function outcomes. The systematic assessment of non-neoplastic kidney tissue at the time of renal surgery can help identify patients at risk of post-operative renal dysfunction. CKDPS represents a standardized and prognostically relevant histologic reporting system for non-neoplastic kidney tissue.

The Association between Income Status and Treatment Selection for Prostate Cancer in a Universal Health Care System: A Population-Based Analysis.

PURPOSE: Treatment selection for localized prostate cancer is guided by risk stratification and patient preferences. While socioeconomic status (SES) disparities exist for access to care, less is known about the effect of SES on treatment decision-making. We sought to evaluate whether income status was associated with the treatment selected (radical prostatectomy [RP] vs radiation therapy [RT]) for nonmetastatic prostate cancer in a universal health care system. MATERIALS AND METHODS: All men from Manitoba, Canada who were diagnosed with nonmetastatic prostate cancer between 2005 and 2016 and subsequently treated with RP or RT were identified using a provincial cancer database. SES was defined as neighborhood income by postal code and divided into income quintiles (Q1-Q5, with Q1 the lowest quintile and Q5 the highest). Multivariable logistic regression nested models were used to compare whether SES was associated with treatment type received. RESULTS: We identified 3,966 individuals who were diagnosed with nonmetastatic prostate cancer and were treated with RP (2,354) or RT (1,612). After adjusting for demographic and clinicopathological characteristics, as income quintile increased, men were incrementally more likely to undergo RP than RT (range Q2 vs Q1: adjusted OR 1.40, 95% CI 1.01-1.93; Q5 vs Q1: adjusted OR 2.30, 95% CI 1.70-3.12). CONCLUSIONS: As income levels increased there was a stepwise incremental increase in the odds of receiving RP over RT for localized prostate cancer. These results may inform initiatives to better understand the values, priorities and barriers that patients experience when making treatment decisions in a universal health care system.

Population-based Assessment of Intermittent Androgen Deprivation Therapy Utilization for Relapsed, Nonmetastatic, Hormone-sensitive Adenocarcinoma of the Prostate.

OBJECTIVES: Androgen deprivation therapy (ADT) is the standard of care for men with nonmetastatic hormone-sensitive prostate cancer (nmHSPC) after treatment failure. Although intermittent ADT (iADT) is noninferior to continuous ADT for prostate cancer outcomes, with superior quality of life and cost-to-benefit ratio, little is known regarding its real-world utilization. The authors aimed to determine the utilization of iADT in a Canadian Provincial Cancer Program for relapsed nmHSPC and identified risk factors associated with the nonreceipt of iADT. MATERIALS AND METHODS: This retrospective population-based cohort study used linked administrative databases to identify all patients with relapsed nmHSPC from 2012 to 2016 and quantified ADT prescription history. Patients were defined as iADT eligible if prostate-specific antigen (PSA) was <4 ng/mL and trending downwards on ≥2 sequential PSAs after ≥6 months of ADT. Univariable and multivariable logistic regression analyses were performed to determine factors associated with nonreceipt of iADT. RESULTS: A total of 601 men with relapsed, nmHSPC were included with a median age at relapse of 73 (range, 46 to 96), pre-ADT PSA of 12.2 ng/mL, and a median pre-ADT PSA doubling time of 7.8 months. 80.9% of the cohort were eligible to receive iADT and 74.4% were treated with iADT. On multivariable analysis, patients originally treated with surgery (odds ratio [OR], 0.19; 95% confidence interval [CI], 0.08-0.46) or having a Gleason Score ≥8 (OR, 0.30; 95% CI, 0.12-0.78) had decreased odds of receipt of iADT. Patients with longer PSA doubling times were more likely to receive iADT (OR, 2.71; 95% CI, 1.17-6.31). CONCLUSIONS: The utilization of iADT was relatively common for men in Manitoba during the study period, however, the uptake of iADT can be improved among identified subgroups.

The impact of fellowship training on pathological outcomes following radical prostatectomy: a population based analysis.

BACKGROUND: Radical prostatectomy (RP) is a common treatment for prostate cancer (PCa). Morbidity, mortality and pathological outcomes may be superior in academic institutions. One explanation may be the involvement of oncology fellowship trained urologists within academic institutions. The literature examining pathological outcomes often lacks individual surgeon data. The objective of this study was to compare pathological outcomes following RP between fellowship trained and non-fellowship trained urologists. METHODS: Population-based, retrospective chart review of men diagnosed with PCa between 2003 and 2008, the majority treated with open approach RP (>99%). Pathological outcomes were compared between oncology fellowship trained academic (FTA), non-fellowship trained academic (NFTA) and non-academic (NA) urologists. Relationships with pathological outcomes were examined utilizing multivariable logistic regression. RESULTS: 83.1% of eligible patients were included in our analysis resulting in 1075 patients. In multivariable analysis, surgeon group was an independent predictor of positive surgical margin (PSM) (p < 0.0001). NFTA and NA urologists were more likely to have PSM compared to FTA urologists (OR 2.50; 95% CI: 1.44-4.35 and OR 2.10; 95% CI: 1.53-2.88, respectively). However, the proportion of PSM between NFTA and NA urologists was not significant (p = 0.492). In addition, pathological stage (p = 0.0004), Gleason sum (p < 0.0001), and surgeon volume (p = 0.017) were associated with PSM. Limitations include retrospective design and lack of clinical and functional outcomes. CONCLUSIONS: Uro-oncology fellowship trained surgeons had significantly lower rates of PSM than non-fellowship trained surgeons in this population based cohort. This study demonstrates the importance of surgeon-related variables on pathological outcomes and highlights the value of additional urologic oncology fellowship training.
