Abstract
In this study retrospectively (from 2 to 2012) and prospectively (from 2012 to 2016) reviewed all cases record for patients with primary malignant, benign aggressive and metastatic tumours of the proximal humerus who were operated at Kasr El-Einy oncology units, The youngest patient was a child 3 years old , the oldest was 79 years old male, with a mean age of 40.9 years , most of cases were in the second decade of life, in this study our concern was not directed to specific age group because proximal humeral tumours occur at any age and management will be the same in resection protocols. Patients were followed up for 12 months -12 years (mean 6 years).Pathological diagnosis of cases after staging was 28 osteosarcoma patients , 19 Ewing’s sarcoma patients ,15 chondrosarcomas patients , 10 benign aggressive disease (five giant cell tumors of bone, five chondroblastoma ) either primary aggressive or recurrent , 5 metastatic disease patients one primary lymphomas of bone, one leiomyosarcoma, one malignant fibrous histocytoma and one recurrent desmoplastic fibroma .Patients were planned by pre-operative management protocol in form of full history, general and local examination. A full laboratory investigations, all patients were subjected to a local and distant screening of the tumor at the time of the diagnosis.All tumors were confirmed pathologically, through either an open or a core biopsy preferred by the same surgeons performing the resection, the pathology specimen was interpreted by a single pathologist after correlation with imaging studies and the surgical team.
