Angiogenesis and Ewing sarcoma--relationship to pulmonary metastasis and survival.

Background/purpose: Intratumoral angiogenesis quantified by microvessel density (MVD) has been shown to be a strong prognostic indicator in a number of malignant tumors. Its association with prognosis in Ewing sarcoma has not been previously studied. The aim of our study was to investigate the relationship between angiogenesis and clinical outcome in Ewing sarcoma.

Tumor angiogenesis and outcome in osteosarcoma.

Intratumoral angiogenesis quantified by microvessel density (MVD) has been shown to be a strong prognostic indicator in a number of malignant tumors. Its association with prognosis in bone sarcomas has been subject to less extensive research. The aim of this study was to investigate prognostic significance of angiogenesis in osteosarcoma.
