            Introduction: Collaboration enables understanding and addressing complex public health problems, such as disparities in childhood cancer survival in low- and middle-income countries. We describe the implementation of VIGICANCER, Colombia's childhood cancer clinical outcomes surveillance system, as an example of a collaborative effort aimed at improving clinical outcomes in children and adolescents with cancer in low- and middle-income countries. Methods: Several collaborative initiatives have been established in resource-constrained settings, demonstrating knowledge gains regarding mechanisms underlying inequities in low-and middle-income countries, and showcasing programs aimed at improving outcomes for children with cancer. These initiatives include “twinning” programs, national, regional, and international partnerships, and research consortia. Results: A notable example is VIGICANCER, implemented in partnership with the Cali Population-Based Cancer Registry, the POHEMA foundation, and the Colombian Association of Pediatric Hematology and Oncology (ACHOP). VIGICANCER has emerged as a benchmark for collaboration and research in Latin America, offering valuable lessons for replication in other low- and middle-income countries. Conclusions: VIGICANCER sets a precedent for future collaborative efforts aimed at providing a comprehensive understanding of epidemiology and drivers of cancer disparities across Colombia, with the goal of improving survival gaps equitably in children and adolescents with cancer in Colombia and other low- and middle-income countries.
