20. key issues and challenges

21. Key Issues/Challenges
Large disparity exists between highly developed and developing/underdeveloped countries in Asia
Issues/challenges, particularly associated with developing/ underdeveloped countries
Smoking epidemic
Air pollution
Lack of disease awareness, robust prevention initiatives, and early screening
Inequality in access to quality care/access to clinical trials (rural vs urban)
Inadequate cancer health care infrastructure
Need for more and better-educated health care professionals
Alternative or traditional approaches to treatment (eg, China and India)

22. Future Directions

23. Important Initiatives Needed to Improve Patient Care
Education and public awareness campaigns on the importance of lifestyle modifications, screening, and early detection/intervention in disease management
Increased governmental support and investment in health care infrastructure/additional resources to ensure more equitable access to care for all segments of the population
Increased funding to train more health care providers to serve underprivileged populations, particularly in rural areas
Increased collaboration between academic centres and the private sector, including pharmaceutical companies, to promote basic scientific research and expedite the development of effective therapies for cancers that are prevalent in Asia

24. Summary
Lung cancer is highly prevalent in Asia, accounting for the majority of new cases diagnosed and responsible for the most cancer-related mortality in the world
The Asia Pacific region has made important contributions to the advancement of the current treatment of lung cancer and continues to be a key area for research and clinical development
However, a number of serious issues and challenges remain
Significant governmental support and investment as well as increased collaboration with the private sector are needed to improve disease management/patient care
