Sample item

A 25-year-old woman has knee pain and an eccentric lytic lesion in the distal femoral epiphysis reaching the subchondral bone, with a soap-bubble look and a pathological fracture risk. What is the treatment of choice?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Extended curettage with adjuvant and bone cement

Giant cell tumour is locally aggressive but usually benign. Extended curettage with an adjuvant such as phenol or liquid nitrogen and cement filling is standard, and resection is reserved for severe cases.

Option by option

  • A. Above-knee amputation

    Amputation is too radical for a tumour that usually responds to local treatment.

  • B. Extended curettage with adjuvant and bone cement (correct)

    Correct. Extended curettage with adjuvant and cement is the usual treatment.

  • C. Radiotherapy

    Radiotherapy carries a risk of malignant transformation and is reserved for inoperable sites.

  • D. Chemotherapy as for osteosarcoma

    Chemotherapy is not effective for giant cell tumour.
