In Lebanon, a small country in the Middle East, there are a total of less than 20 pediatric oncologists, who work at multiple hospitals across the country. In 2012, within a program development initiative sponsored by St Jude Children’s Research Hospital, the majority of pediatric oncologists agreed to establish a cooperative group, within which to initiate collaborative treatment programs for childhood tumors. The hypothesis is that centralized diagnosis and staging and coordinated treatment would result in better patient outcomes. Outcome would also be improved by enhanced access to technically specialized and expensive procedures by eliminating financial barriers, and ensuring expert care.

To establish feasibility, the newly formed group (Lebanese Children’s Oncology Group, LCOG) focused first on pediatric bone tumors. The most common malignant pediatric bone tumors are Osteosarcoma and Ewing sarcoma.

Patients aged below 18 years diagnosed with Ewing’s Sarcoma or Osteosarcoma that were enrolled on the collaborative Bone Tumor and in the period of July 1 2012 to June 30 2015

 Retrospective chart review will be applied to all children diagnosed with Ewing’s Sarcoma and Osteosarcoma that were enrolled on the Collaborative Bone Tumor program between July 1, 2012 and June 30, 2015

Collected data include chemotherapy details, associated delays and toxicities, local control modality (surgery, radiation), acute and chronic complications, and patient outcome
