Cancer is a major global health burden, with rising incidence. However, prevention is possible and effective for many cancer types and known risk factors. Primary cancer prevention (PCP) focuses on reducing exposure to these risks, as outlined in the European Code Against Cancer. Key factors include smoking, second-hand smoke, poor diet, obesity, physical inactivity, alcohol abuse, sun exposure, workplace carcinogens, and infections like HBV and HPV. An estimated 30% to 45% of cancers could be prevented through healthier lifestyles, reducing risks for multiple cancer types. The International Agency for Research on Cancer (IARC) confirms the preventive impact of smoking cessation, weight control, sun protection, exercise, and reduced alcohol consumption.
Despite strong evidence supporting prevention programmes, their effectiveness is hindered by socioeconomic inequalities, poor integration into routine practice, and barriers to behavioral change. Implementation challenges stem from ineffective processes, lack of planning, and failure to adapt programmes to local settings. Consequently, evidence-based programmes (EBPs) that succeed in controlled trials often fail in real-world applications, leading to persistent health disparities and inefficient use of resources.
Implementation science, the study of methods to integrate research into practice, provides insights into overcoming these barriers. It identifies key factors influencing successful PCP implementation, such as individual reluctance, organizational gaps, and political inertia. Common obstacles include healthcare providers' doubts about intervention effectiveness, patients' low motivation, lack of institutional resources, and policymakers' reluctance to invest in long-term gains beyond election cycles.
PCP strategies are fragmented across Europe, leading to disparities. Solutions to enhance implementation remain scarce and poorly contextualized. Policymakers, health stakeholders, and clinicians need effective implementation strategies to address barriers and improve outcomes. Given the high prevalence of modifiable risk factors and the rising cancer burden, implementation science is essential for public health.
Tailored implementation, a key concept in this field, customizes strategies to local settings by engaging stakeholders, identifying barriers, adapting interventions, and evaluating outcomes. This approach acknowledges that a one-size-fits-all solution is ineffective and emphasizes the need for context-specific strategies. Though still evolving, tailored implementation has shown promise in improving programme outcomes.
In summary, the growing cancer burden underscores the urgency of addressing modifiable risk factors. While EBPs are effective in controlled settings, real-world implementation faces challenges. Decision-makers need structured methods to adapt and implement prevention programmes effectively.
The PIECES project (Agreement 101104390) aims to enhance the implementation of EBPs for PCP by addressing a range of risk factors and behavior change mechanisms to reduce cancer incidence in the EU and beyond. The project focuses on smoking, alcohol consumption, physical inactivity, HPV infection, sun exposure, and diet. Rather than testing effectiveness, PIECES emphasizes implementation processes and outcomes.
Specifically, PIECES will develop, test, and disseminate a systematic framework for selecting, adapting, and implementing PCP programmes at individual, organizational, and policy levels. It will provide an integrated toolkit to guide structured identification, tailoring, and application of EBPs, ensuring interventions are customized to local barriers and implementation contexts.
