[Radiotherapy in advanced osseous destruction in chronic myeloid leukemia. A case report]

Chronic myelocytic leukemia is a disease of myeloproliferative disorder. In chronic myelocytic leukemia occasionally myelosarcomas occur as defined tumors which can cause localized symptoms. We report a case of successful palliative radiotherapy.A 44-year-old patient with total destruction of the left humerus caused by myelosarcoma of the bone in chronic myelocytic leukemia was treated with percutaneous megavoltage radiotherapy, the total applied dose was 40 Gy. After radiotherapy the patient was free of pain. The tumorous swelling of soft tissue subsided completely, there was total formation of callus in the affected humerus and the patient could be mobilized.This case report confirms the high effectiveness of palliative radiotherapy even in advanced cases of myelosarcomas which has been described in literature.
