01
Why Do We Work with the World?

Many types of childhood cancer are rare, making it difficult for any single country to collect enough data on its own. For this reason, JCCG works closely with partners around the world, pooling knowledge and resources to develop better approaches to diagnosis and treatment for children with cancer.

• Through active participation in international research networks—such as the International BFM Study Group and collaborations with leading groups including the Children’s Oncology Group in North America—JCCG promotes global cooperative studies that would not be possible within Japan alone.
• Currently, these collaborations include joint research on infant leukemia, leukemia associated with Down syndrome, as well as pediatric brain tumors and cancers of the liver and kidney. By working together internationally, we are advancing the development of new and more effective treatments across a wide range of childhood cancers.
• JCCG also actively shares knowledge in both directions. Our members participate in major international scientific meetings, such as the SIOP and the American Society of Hematology, bringing the latest global insights to Japan while sharing research results from Japan with the rest of the world.

Research Results That Benefit the World

The results of JCCG’s research are shared with physicians and researchers around the world through publications in scientific journals, helping to improve the care of children with cancer globally.

• Cancer Genomic Testing
  Our research demonstrated that cancer genomic profiling (CGP) is useful in identifying the most appropriate treatment for each child. (November 2025)
• Leukemia Treatment
  We established treatment approaches that reduce the burden on the body while improving survival rates. (February 2025)

03
Supporting Our Partners Across Asia

JCCG works closely with partners across Asia, using online meetings and other forms of collaboration to support the improvement of local medical care. Through these efforts, we also contribute to the training and development of physicians, helping to strengthen pediatric cancer care throughout the region.
