Cancer research in South Asian Association for Regional Cooperation (SAARC) countries.

Cancer is a major global health threat, with 35 million new cases projected by 2050, predominantly in low-income and middle-income-countries. Within South Asian Association for Regional Cooperation (SAARC) countries, a notable gap in cancer research investment and output compared with high-income countries highlights the need to strengthen research capacity. The rising cancer incidence across SAARC countries is not being matched by local research, particularly in clinical trials in molecular biology, targeted therapy, immunotherapy, and cancer vaccines. This paucity of research is problematic as guidelines and therapies developed in high-income countries might not be directly applicable to low-income and middle-income countries due to distinct regional sociocultural, genetic, and environmental factors and are often impractical in these countries due to cost and implementation challenges. This Series paper examines the cancer research landscape within SAARC countries, focusing on Bangladesh, Nepal, Sri Lanka, India, Pakistan, Afghanistan, Bhutan, and Maldives. We analyse PubMed publication rates and examine available infrastructure, current research (including clinical trials), and limitations and disparities among SAARC countries in terms of cancer research. Key challenges include disparities in health-care access, cultural and economic barriers, and little funding and infrastructure. Strengthening cancer research in SAARC countries requires building collaborative networks, improving research facilities and training, focusing on local epidemiological studies, and developing affordable technologies and treatments. Effective policy and stakeholder engagement could greatly advance cancer care in the region.
