Cancer research funding in South Asia

Background: The rising burden of cancer significantly influences the global economy and healthcare systems. While local and contextual cancer research is crucial, it is often limited by the availability of funds. In South Asia, with 1.7 million new cancer cases and 1.1 million deaths due to cancer in 2020, understanding cancer research funding trends is pivotal.Methods: We reviewed funded cancer studies conducted between January 1, 2003, and Dec 31, 2022, using ClinicalTrials.gov, International Cancer Research Partnership (ICRP) Database, NIH World RePORT, and WHO International Clinical Trials Registry Platform (ICTRP). We included funded studies related to all cancer types, conducted in South Asian countries, namely Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka.Results: We identified 6561 funded cancer studies from South Asia between 2003 and 2022, increasing from 400 studies in 2003-2007 to 3909 studies in 2018-2022. India had the highest number of funded cancer studies, while Afghanistan, Bhutan, and the Maldives had minimal or no funded cancer research output. Interventional studies (67.3%) were the most common study type funded. The most common cancer sites funded were breast (17.8%), lung (9.9%), oropharyngeal (6.2%), and cervical (5.0%) cancers. On the WHO ICTRP, international funding agencies contributed to a majority of studies (57.5%), except in India where local funding agencies (58.2%) funded more studies.Conclusion: This study identified gaps in research funding distribution across cancer types and geographic areas in South Asia. This data can be used to optimize the distribution of cancer research funding in South Asia, fostering equitable advancement in cancer research

Colon cancer survival among South Asian Americans: A cross-sectional analysis of a national dataset

Introduction: Colon cancer (CC) is one of the most common cancers among South Asian Americans (SAAs). The objective of this study was to measure differences in risk-adjusted survival among SAAs with CC compared to non-Hispanic Whites (NHWs) using a representative national dataset from the United States.Methods: A retrospective analysis of patients with CC in the National Cancer Database (2004-2020) was performed. Differences in presentation, management, median overall survival (OS), three-year survival, and five-year survival between SAAs and NHWs were compared. Kaplan-Meier analysis and multivariable Cox regression were used to assess differences in survival outcomes, adjusting for demographics, presentation, and treatments received.Results: Data from 2873 SAA and 639,488 NHW patients with CC were analyzed. SAAs were younger at diagnosis (62.2 versus 69.5 y, P \u3c 0.001), higher stage (stage III [29.0% versus 26.2%, P = 0.001] or Stage IV [21.4% versus 20.0%, P = 0.001]), and experienced delays to first treatment (SAA 5.9% versus 4.9%, P = 0.003). SAAs with CC had higher OS (median not achieved versus 68.1 mo for NHWs), three-year survival (76.3% versus 63.4%), and five-year survival (69.1% versus 52.9%). On multivariable Cox regression, SAAs with CC had a lower risk of death across all stages (hazard ratio: 0.64, P \u3c 0.001).Conclusions: In this national study, SAA patients with CC presented earlier in life with more advanced disease, and a higher proportion experienced treatment delay compared to NHW patients. Despite these differences, SAAs had better adjusted OS than NHW, warranting further exploration of tumor biology and socioeconomic determinants of cancer outcomes in SAAs
