Comment on Kasai et al.: Clinical profile of long-term survivors of breast or thyroid cancer with metastatic spinal tumours.

We read with great interest the paper by Kasai et ]

published in International Orthopaedics. We congratulate the

authors on their work. We agree with them on one point and

disagree on another one. The first is that a long time (above

5 years) between diagnosis of the thyroid cancer and the

operation for the spinal metastases would be a good

prognostic sign. However, we disagree that the “surgical

strategy for spinal metastases” developed by us [5] would

not expect survival in patients with spinal metastases from

thyroid cancer.
