Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Area of Science:

  • Oncology
  • Public Health
  • Radiology

Background:

  • Lung cancer is the leading cause of cancer mortality globally and in Chile, with smoking as the primary risk factor.
  • Low-dose computed tomography (LDCT) has demonstrated reduced mortality in lung cancer screening, yet Chile lacks formal screening guidelines.
  • This initiative sought to establish expert-driven recommendations for lung cancer screening tailored to the Chilean context.

Framework:

  • A mixed-methods approach combined a literature review with a Delphi panel of 18 Chilean experts.
  • The RAND/UCLA method and evidence-based decision-making criteria guided the consensus process over three voting rounds and a synchronous meeting.
  • The study identified 25 key recommendations for lung cancer screening in Chile.

Implementation:

  • Recommendations encompass defining the target population, determining screening frequency and duration, and outlining program characteristics.
  • Considerations for the health institutions responsible for program delivery were also addressed.
  • Selected recommendations focus on the practical aspects of establishing and running lung cancer screening programs.

Implications:

  • Experts raised concerns regarding the feasibility and acceptability of implementing screening programs due to potential barriers such as cost and public awareness.
  • Generating local evidence is crucial to address Chile's specific regional particularities.
  • Ensuring the effectiveness and successful integration of lung cancer screening programs in Chile requires addressing identified challenges and tailoring strategies to the local healthcare landscape.
