Outcome of Ewing's sarcoma of the scapula–a long-term follow-up study

A child with Ewing's sarcoma in scapula: A rare case report

“…ES commonly involves femur, tibia, humerus, fibula and pelvis [4] . Scapula is a rare site for bone tumors (3%), and most scapular tumors are malignant [8] . The most common tumors affecting scapula are chondrosarcoma and osteosarcoma.…”

“…The most common tumors affecting scapula are chondrosarcoma and osteosarcoma. In a cohort study about patients diagnosed with ES between 1988 and 2018, only 29 cases were involved in the scapula [8] . There are 12 cases of congenital ES have been reported in the medical literature, 3 of them were in the shoulder girdle [9] .…”

“…Surgery with neoadjuvant chemotherapy is considered better for total survival in ES of scapula in comparison with chemotherapy and/or radiotherapy alone. On the other hand, patients with marginal resection and a chemotherapy response of <100% had the worst outcome [8] . Local recurrence did not have significant effect on total survival [8] .…”

“…On the other hand, patients with marginal resection and a chemotherapy response of <100% had the worst outcome [8] . Local recurrence did not have significant effect on total survival [8] . Long term follow-up should be done after primary management in order to detect any secondary malignancies and growth-related musculoskeletal complications.…”

“…Long term follow-up should be done after primary management in order to detect any secondary malignancies and growth-related musculoskeletal complications. The Musculoskeletal Tumor Society Score (MSTS) was used to assess the function of scapula, and according to Malik et al the median MSTS score was 67.4% [8] . The prognosis of ES depends on many factors: anatomic location, tumor stage and size, necrosis next to chemotherapy, presence or absence of metastases, raised serum LDH levels and older age (> 15 years old) [15] .…”
