Metastatic multicentric epithelioid angiosarcoma of bone. A case report with pitfalls. Tumor seeding after percutaneous biopsy and hypercalcemia.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Angiosarcomas are a type of malignant tumor of vascular origin. They represent <1% of all primary bone tumors. The multicentric or metastatic does not differ in its high aggressiveness and poor prognosis. A 72-year-old male with bone angiosarcoma initially located in proximal femur. After biopsy in a non-expert sarcoma center, he presented tumor involvement in the needle trajectory and multicentric/metastatic involvement at the sacro-coccygeal level. He associated tumoral-hypercalcemia and was referred to our sarcoma center. He was treated by tumoral resection and tumor prosthesis. In the follow-up he presented pulmonary metastasis and new implants, dying 2 months later. Multicentric or metastatic bone involvement in angiosarcomas has only theoretical relevance for their management. Biopsy should be performed in sarcoma centers due to the risk of dissemination. Although hypercalcemia in sarcomas is uncommon, we highlight its investigation.
