Acute lymphoblastic leukemia (ALL) constitutes approximately 25% of the pediatric cancers. In general, the task of identifying immature leukemic blasts from normal cells under the microscope is challenging because morphologically the images of the two cells appear similar.


Challenge is split into 3 separate phases:

  • Train set composition:

    Total subjects: 73, ALL (cancer): 47, Normal: 26

    Total cell images: 10,661, ALL(cancer): 7272, Normal: 3389

  • Preliminary test set composition:

    Total subjects: 28, ALL (cancer): 13, Normal: 15

    Total cell images: 1867, ALL(cancer): 1219, Normal: 648

  • Final test set composition:

    Total subjects: 17, ALL (cancer): 9, Normal: 8

    Total cell images: 2586
