Bone tumors

Fibrosarcoma of bone

BoneMalignant / sarcomaFibrogenic tumours of bone

Epidemiology

A rare primary sarcoma of bone, now diagnosed with more caution because of the molecular reclassification of many tumors. That is why pathology review at an experienced center is decisive before treatment is settled.

Basic features

It produces a destructive lesion with no obvious bone or cartilage matrix, so an expert biopsy is key.

Usual treatment

It is treated with wide resection and consideration of radiotherapy or chemotherapy according to grade, site, and extent. Before chemotherapy starts it is worth discussing fertility preservation with the team, because some of these treatments can affect it and the options have to be raised beforehand.

Outcomes and prognosis

The risk of recurrence and metastasis depends on the grade and on achieving negative margins; the prognosis varies widely according to the grade.

Warning signs

These signs do not necessarily mean cancer, but they warrant evaluation before operating on or needling a mass.

  • A soft-tissue mass that grows, is larger than 5 cm, or is deep.
  • Persistent, night-time or progressive bone pain, especially if it limits activity.
  • A fracture from minimal trauma, or an aggressive bone lesion on an X-ray.
  • A lump that comes back after previous surgery.
  • Neurological symptoms, rapid swelling, or pain associated with a mass.

This information is general and does not replace a medical evaluation. A musculoskeletal tumor must be interpreted together with imaging, physical examination, biopsy when appropriate and each patient's context.

Specialist evaluation

If you have a mass, a bone lesion or a report suggesting a tumor, book an evaluation.
