Treatment of Anaplastic Thyroid Cancer with Symptomatic or Threatening Bone Metastases
Bone metastases in anaplastic thyroid cancer require urgent, targeted intervention. The primary clinical goal is relief of bone pain and prevention of skeletal complications. The recommended approach depends critically on whether the affected bone is structurally intact or compromised.
Clinical Scenario
This protocol applies to anaplastic thyroid cancer with bone metastases that are symptomatic or pose a structural threat — including situations where a weight-bearing bone is at risk or spinal cord compression is threatened. The appropriate first intervention differs between these presentations.
Treatment Approach (Overview)
Management centres on palliative radiotherapy, with a bone-stabilising surgical step required first in cases of structural compromise, and the addition of bone-protective systemic agents throughout.
Specific fractionation schedules, sequencing criteria, agent selection, and supportive supplementation are detailed in the full structured protocol.
Clinical Goal
Relief of bone pain.

- In patients with ATC with symptomatic or threatening bone metastases—but without structural compromise or threatened spinal cord compression in need of surgical remediation—we recommend palliative radiotherapy.
- In patients with ATC with bone metastasis causing structural compromise in a weight-bearing region or threatening spinal cord compression, we recommend orthopedic fixation before initiation of palliative radiotherapy.
- In patients with ATC with bone metastasis, we suggest periodic intravenous bisphosphonate infusions or subcutaneous RANK ligand inhibitor.
