title: Primary malignant tumours of the scapula--a review of 29 cases.
abstract: OBJECTIVE
  Primary malignant bone tumours of the scapula are very rare. Apart from limited small series and some case reports, international literature on flat bone sarcoma is exiguous and not much is known about the oncological outcome.
  
  
  METHODS
  A retrospective analysis of 29 patients diagnosed with a primary malignant tumour of the scapula was performed. The mean age was 40 years. The average time of follow-up was 60 months. Diagnoses included chondrosarcoma in 11 patients, Ewing's sarcoma/PNET in six, osteosarcoma in three, and others in nine.
  
  
  RESULTS
  Five patients (19%) had no surgery. Wide resection was performed in 18 patients (74%) and marginal and intralesional resection in three patients (13%) each. Fifteen patients underwent resection without bony reconstruction, seven patients underwent a Tikhoff-Linberg procedure, and two patients received a custom-made scapula prosthesis. Six patients were diagnosed with metastasis after a mean time of nine months after surgery, while three patients suffered local recurrence at an average of six months after surgery. Disease-specific survival was 70% at one year and 47% at five years. The mean MSTS score was 69% and was highest for patients with scapular prosthesis.
  
  
  CONCLUSIONS
  The overall prognosis of primary malignant bone tumours of the scapula remains to be inferior compared to extremity sarcoma. Endoprosthetic reconstruction, however, shows promising functional results even in cases of total scapulectomy.
