Context: Among patients with advanced life-limiting illness, an inaccurate understanding of prognosis is common and associated with negative outcomes. Recent years have seen an emergence of new interventions tested for their potential to improve prognostic understanding. However, this literature has yet to be synthesized.Objectives: To identify and characterize tested interventions, summarize intervention findings, and outline directions for future research.Methods: Systematic searches were conducted in five databases - PubMed/MEDLINE (NLM), EMBASE (Elsevier), CINAHL (EBSCO), PsycINFO (OVID), and Cochrane Central Register of Controlled Trials (Wiley) - to identify interventions evaluated within a randomized controlled design for their impact on prognostic understanding.Results: Of the 2354 initial articles, 12 were selected for final inclusion, representing nine unique interventions. Intervention types included decision aids accompanying medical consults, palliative care consultations, communication training for patients and physicians, and targeted discussions regarding prognosis and treatment decision making. Common components of interventions included provision of prognostic information, assistance with end-of-life care planning, and provision of decisional and emotional support during discussions. Most interventions were associated with some indication of improvement in prognostic understanding. However, even after intervention, inaccurate prognostic understanding was common, with 31-95 percent of patients in intervention groups exhibiting inaccurate perceptions of their prognosis.Conclusion: Prognostic understanding interventions hold the potential to improve patient understanding and thus informed decision making, but limitations exist. Future research should examine why many patients receiving intervention may continue to maintain inaccurate perceptions, and identify which intervention components can best enhance informed, value-consistent decision making.

Prostate cancer remains the second most common cancer among men. Screening is gaining acceptance, likely reducing mortality at the cost of overdiagnosis and overtreatment. Increasing use of magnetic resonance imaging and biomarkers may mitigate some of the negative consequences of screening. Prostate cancer (PCa) is one of the most common cancers worldwide. Understanding the epidemiology and risk factors of the disease is paramount to improve primary and secondary prevention strategies. To systematically review and summarize the current evidence on the descriptive epidemiology, large screening studies, diagnostic techniques, and risk factors of PCa. PCa incidence and mortality rates for 2020 were obtained from the GLOBOCAN database of the International Agency for Research on Cancer. A systematic search was performed in July 2022 using PubMed/MEDLINE and EMBASE biomedical databases. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines and was registered in PROSPERO (CRD42022359728). Globally, PCa is the second most common cancer, with the highest incidence in North and South America, Europe, Australia, and the Caribbean. Risk factors include age, family history, and genetic predisposition. Additional factors may include smoking, diet, physical activity, specific medications, and occupational factors. As PCa screening has become more accepted, newer approaches such as magnetic resonance imaging (MRI) and biomarkers have been implemented to identify patients who are likely to harbor significant tumors. Limitations of this review include the evidence being derived from meta-analyses of mostly retrospective studies. PCa remains the second most common cancer among men worldwide. PCa screening is gaining acceptance and will likely reduce PCa mortality at the cost of overdiagnosis and overtreatment. Increasing use of MRI and biomarkers for the detection of PCa may mitigate some of the negative consequences of screening. Prostate cancer (PCa) remains the second most common cancer among men, and screening for PCa is likely to increase in the future. Improved diagnostic techniques can help reduce the number of men who need to be diagnosed and treated to save one life. Avoidable risk factors for PCa may include factors such as smoking, diet, physical activity, specific medications, and certain occupations. [ABSTRACT FROM AUTHOR]
