Dear SIOP Members and Friends,


The SIOP community expresses its deepest condolences to the healthcare team, patients and families at Okhmatdyt Children’s Cancer Hospital in Kyiv, Ukraine, for the recent death of hematologist Dr. Oksana Leontieva due to ongoing missile strikes on civilian targets.

We renew our call for the protection of healthcare workers, their patients, and families. When military action creates a humanitarian crisis, healthcare workers are placed directly in danger on the frontlines and the children they care for suffer the most.


Guillermo Chantada, SIOP President

on behalf of the SIOP Community
