Mortality Among Men with Advanced Prostate Cancer Excluded from the ProtecT Trial.

ABSTRACT:

Background

Early detection and treatment of asymptomatic men with advanced and high-risk prostate cancer (PCa) may improve survival rates.

Objective

To determine outcomes for men diagnosed with advanced PCa following prostate-specific antigen (PSA) testing who were excluded from the ProtecT randomised trial.

Design, setting, and participants

Mortality was compared for 492 men followed up for a median of 7.4 yr to a contemporaneous cohort of men from the UK Anglia Cancer Network (ACN) and with a matched subset from the ACN.

Outcome measurements and statistical analysis

PCa-specific and all-cause mortality were compared using Kaplan-Meier analysis and Cox's proportional hazards regression.

Results and limitations

Of the 492 men excluded from the ProtecT cohort, 37 (8%) had metastases (N1, M0=5, M1=32) and 305 had locally advanced disease (62%). The median PSA was 17μg/l. Treatments included radical prostatectomy (RP; n=54; 11%), radiotherapy (RT; n=245; 50%), androgen deprivation therapy (ADT; n=122; 25%), other treatments (n=11; 2%), and unknown (n=60; 12%). There were 49 PCa-specific deaths (10%), of whom 14 men had received radical treatment (5%); and 129 all-cause deaths (26%). In matched ProtecT and ACN cohorts, 37 (9%) and 64 (16%), respectively, died of PCa, while 89 (22%) and 103 (26%) died of all causes. ProtecT men had a 45% lower risk of death from PCa compared to matched cases (hazard ratio 0.55, 95% confidence interval 0.38-0.83; p=0.0037), but mortality was similar in those treated radically. The nonrandomised design is a limitation.

Conclusions

Men with PSA-detected advanced PCa excluded from ProtecT and treated radically had low rates of PCa death at 7.4-yr follow-up. Among men who underwent nonradical treatment, the ProtecT group had a lower rate of PCa death. Early detection through PSA testing, leadtime bias, and group heterogeneity are possible factors in this finding.

Patient summary

Prostate cancer that has spread outside the prostate gland without causing symptoms can be detected via prostate-specific antigen testing and treated, leading to low rates of death from this disease.

Project description:BackgroundMen with metastatic castrate-resistant prostate cancer can experience an array of treatment-related side effects. Accumulating evidence suggests exercise may alleviate some of these adversities and assist in disease management. However, empirical evidence in advanced prostate cancer patients remains limited. The purpose of this study is to determine whether men with metastatic prostate cancer, who are ineligible for high-intensity exercise, can partake in a home-based, moderate-intensity exercise program and the impact of doing so on quality of life and physical fitness parameters.MethodsThirty men with adenocarcinoma of the prostate and progressive systemic, metastatic disease will be recruited. Clinicians will screen patients against inclusion criteria to determine eligibility. All men enrolled will be prescribed a tailored, home-based, moderate-intensity exercise intervention consisting of aerobic and strengthening components for 12 weeks. Patients will receive supplementary education materials and weekly behavioural change consultations throughout the intervention. The primary outcome will be the feasibility of delivering such an intervention in men with metastatic disease. Secondary endpoints including skeletal events will be monitored for safety, as will the feasibility of patient-reported outcome measures and the sampling time points, generating data pertaining to completion rates and potential effect in future trials. General physical fitness will be assessed during these visits, using timed sit-to-stand testing and a 6-min walking test. Prior to each visit, objective physical activity levels will be captured for 7 days using an accelerometer, to determine the feasibility of this technology and the quality of data obtained. In parallel with the feasibility aspects of the trial, changes compared to baseline will be reported. Direct regular contact will also serve as a feedback loop, should any issues arise. This study has received ethical approval from the Office for Research Ethics Committees Northern Ireland.ConclusionsThis study aims to determine the potential utility of a home-based exercise intervention in managing side effects associated with advanced prostate cancer and its treatment. This feasibility trial will inform the design and implementation of a larger randomised control trial to determine the efficacy of moderate aerobic and strengthening exercise as an adjuvant therapy in men with metastatic prostate cancer. Collecting such evidence provides further support for exercise in this paradigm and potential for its inclusion as a low-toxicity therapy in standard cancer care, in the longer term.Trial registrationClinicalTrials.gov, NCT03658486Trial sponsor: Queen's University Belfast (Reference: B18/15).

Project description:PurposeTo describe a newly established international registry recruiting diverse patients with advanced prostate cancer across academic and community practices to address unmet needs in this population.Patients and methodsInitiated in 2017, IRONMAN (International Registry for Men with Advanced Prostate Cancer) is a prospective cohort of patients with advanced prostate cancer. The study will enroll 5,000 patients with metastatic hormone-sensitive prostate cancer (mHSPC) or castration-resistant prostate cancer (CRPC), recruited from Australia, the Bahamas, Barbados, Brazil, Canada, Ireland, Jamaica, Kenya, Nigeria, Norway, South Africa, Spain, Sweden, Switzerland, the United Kingdom, and the United States. The study is collecting datatypes to study variation in care and treatment of advanced prostate cancer across countries and across academic, community-based, and government practices with a focus on clinical outcomes, patient-reported outcomes, epidemiologic data, biologic subtypes, and clinician questionnaires.ResultsThrough July 2022, 2,682 eligible patients were enrolled in 11 of 12 active countries. Sixty-six percent of patients have mHSPC, and 34% have CRPC. On the basis of self-report, 11% of patients are Black and 9% are Hispanic. Five Veterans Affairs Medical Centers are enrolling patients. Globally, 23% of patients report being veterans of military service.ConclusionTo our knowledge, this is the first international cohort of people newly diagnosed with advanced prostate cancer designed to describe variations in patient management, experiences, and outcomes. IRONMAN aims to identify optimal treatment sequences to improve survival, understand patient-reported outcomes, and explore novel biomarkers to understand treatment resistance mechanisms. Insights from IRONMAN will inform and guide future clinical management of people with mHSPC and CRPC. This cohort study will provide real-world evidence to facilitate a better understanding of the survivorship of people with advanced prostate cancer.

Project description:BackgroundElderly patients (≥65yr) with advanced prostate cancer and cardiovascular disease (CVD) conditions are often excluded from clinical trials of abiraterone acetate (AA) or enzalutamide (ENZ). Consequently, little is known about the effects of these medications on these vulnerable patients.ObjectiveTo assess the short-term outcomes of AA and ENZ in patients with pre-existing CVDs.Design, setting, and participantsA population-based retrospective study. The Surveillance, Epidemiology, and End Results-Medicare-linked database was used to identify prostate cancer patients using AA or ENZ.Outcome measurements and statistical analysisThe primary endpoint was 6-mo all-cause mortality, analyzed using modified Poisson regression modeling of relative risk (RR) adjusted for confounders and comorbidities.Results and limitationsAmong eligible patients (2845 with AA and 1031 with ENZ), 67% had at least one pre-existing CVD. Compared with those without pre-existing CVDs, having one to two pre-existing CVDs was associated with 16% higher 6-mo mortality (RR=1.16, 95% confidence interval [CI]: 1.00-1.36), and the risk increased further among those having three or more CVDs (RR=1.56, 95% CI: 1.29-1.88). Most of the differences in survival of patients with pre-existing CVD condition occurred within the first 6mo of treatment.ConclusionsAfter treatment with AA or ENZ, elderly prostate cancer patients with pre-existing CVDs experienced higher short-term mortality than otherwise similar patients without CVDs. Mortality associated with CVDs did not depend on having received AA versus ENZ.Patient summaryPatients with pre-existing cardiovascular diseases (CVDs) experienced higher short-term mortality after abiraterone acetate or enzalutamide than those without pre-existing CVDs. It is recommended that a multidisciplinary team, including a cardiologist, evaluate patients having pre-existing CVDs in the process of making treatment decisions and monitoring potential side effects.

Project description:ImportanceContinuing prostate-specific antigen (PSA) screening after age 70 years might benefit men at high risk of prostate cancer-specific mortality (PCSM) or metastatic prostate cancer (mPCa), but the relative value of clinical factors (race and ethnicity, competing mortality, and PSA history) in identifying men at higher vs lower risk is unknown.ObjectiveTo examine the value of PSA levels, race and ethnicity, and competing mortality in risk stratification for PCSM and mPCa in men after age 70 years.Design, setting, and participantsIn this cohort study, clinical data of all men receiving health care through the Veterans Health Administration who turned age 70 years between 2008 and 2020 and had a normal screening PSA value between age 65 and 69 years (<4 ng/mL [baseline PSA]) and no prior history of prostate cancer or biopsy were examined. The data cutoff date was December 26, 2023.ExposureThe most recent screening PSA value from age 65 to 69 years, self-reported race and ethnicity, and competing mortality risk derived from a machine learning model.Main outcome and measuresThe 10-year absolute risk of PCSM and mPCa were determined using regression modeling.ResultsThe cohort included 921 609 men who turned 70 years between 2008 and 2020; 11% of whom self-reported as Black and 82% as White race. Between age 65 and 70 years, 45% of patients had a baseline PSA of less than 1.00 ng/mL, and 32% had a baseline PSA of 1.00 to 1.99 ng/mL. Most patients (87%) continued to undergo screening past age 70 years, with little variation by competing mortality risk or race and ethnicity. The 10-year cumulative incidence of PCSM was 0.26% overall, and 95% of men had a 10-year risk less than 0.73%. Higher baseline PSA level between age 65 and 69 years was associated with 10-year PCSM risk (0.79% for 3.00-3.99 ng/mL vs 0.10% for 0.20-0.99 ng/mL), race and ethnicity (0.36% for Black vs 0.25% for White), and competing mortality (0.24% for the highest quintile vs 0.21% for the lowest quintile). Similar results were found for mPCa. Low PSA (0.20-0.99 ng/mL) was associated with very low PCSM and mPCa risk, even among Black men in the healthiest quintile of competing mortality risk (10-year PCSM risk, 0.08% [95% CI, 0.01%-0.44%]; 10-year mPCa risk 0.24% [95% CI, 0.10%-0.52%]).Conclusions and relevanceIn this cohort study, the findings suggest that most men receiving care through the VHA continue PSA screening after age 70 years despite low absolute 10-year PCSM risks. The PSA values from age 65 to 69 years may be highly informative for adverse prostate cancer outcomes after age 70 years, with a PSA less than 1 ng/mL associated with a very low risk of long-term PCSM and mPCa.
