Key result
Abdominal metastasis in osteosarcoma is a late manifestation and terminal prognostic indicator, with both reported cases quickly followed by patient decline and death.
Case Report (n=2)
Abdominal metastasis in osteosarcoma is a late manifestation and terminal prognostic indicator, though early detection may improve palliative care.
Abdominal metastasis signals terminal osteosarcoma; leaves open optimal surveillance strategies in advanced disease.
Two cases of primary distal femur osteosarcoma with subsequent metastasis to the abdomen are presented. In both cases, the development of abdominal metastasis was quickly followed by patient decline and death. A review of the literature was performed, assessing the presentation and survival of patients with osteosarcoma metastasized to the abdomen. As illustrated by the current cases and the literature review, abdominal metastasis in osteosarcoma is often a late manifestation and terminal prognostic indicator. Nonetheless, early detection and prompt intervention of this less common site of disease metastasis may improve patient care and palliative therapy.
