Primary bone sarcomas

1 / First assessment

Establish the diagnosis before treatment.

Persistent bone pain, swelling or a concerning X-ray needs assessment, but these findings have other possible causes. X-rays and further imaging describe the lesion; tissue examination establishes the tumour type.

MRI assesses local extent. Staging tests look for disease elsewhere and are chosen for the suspected diagnosis. They are not one fixed scan package for every patient.

2 / Planning the sample

Biopsy is part of the treatment plan.

Imaging should precede biopsy when a bone sarcoma is suspected. The team planning definitive treatment should help choose the target and route, because the biopsy site can affect later surgery.

If biopsy or surgery has already happened, bring the pathology report, available slides or blocks, scans and operation records. Reviewing existing material may help clarify the diagnosis before another procedure.

3 / Different diseases

The tumour type changes the sequence of care.

Osteosarcoma, Ewing sarcoma and chondrosarcoma differ in their biology and response to treatment. The pathology result therefore needs to be considered with the imaging and clinical findings.

At Aster MIMS Kannur, sarcoma pathology review, medical oncology and a regular multidisciplinary tumour board support this planning.

• Osteosarcoma: many high-grade tumours are treated with chemotherapy and surgery. Some lower-grade tumours follow a different plan.
• Ewing sarcoma: chemotherapy is combined with surgery, radiotherapy or both for control of the original tumour.
• Chondrosarcoma: surgery is central for many cases. Chemotherapy or radiotherapy has selected roles that depend on subtype and circumstances.

4 / The operation

Discuss tumour clearance and useful function.

Surgery aims to remove the tumour with an appropriate margin of surrounding tissue. Depending on the site, reconstruction may be needed after removal.

Limb-preserving surgery is considered where appropriate, but it is not suitable for every tumour. Discuss the likelihood of complete removal, expected function, possible complications and relevant alternatives, including amputation when indicated.

5 / After treatment

Recovery includes more than wound healing.

The operation and any reconstruction influence restrictions, rehabilitation and return to activities. Ask for a plan that also accounts for chemotherapy or radiotherapy when these are part of treatment.

Follow-up assesses possible recurrence, function and treatment effects. Some effects appear later, so keep a treatment summary and agreed follow-up plan. Report persistent new symptoms between appointments rather than waiting for the next scheduled scan.

Rehabilitation and a dedicated plastic and reconstructive surgery department are available at Aster MIMS Kannur when the treatment plan requires their support.
