Stereotactic Ablative Radiotherapy for Bone Metastasis of Gastrointestinal Stromal Tumor: Case Report and Review of the Literature

Background: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. These tumors are rare and only make bone metastases at a rate of 5%. Case summary: A 31-year-old male with a GIST presented with solitary bone metastasis at the right iliac bone. We performed stereotactic ablative radiotherapy (SABR) and achieved excellent local control. Herein, our case is presented, and a short review of the literature is carried out. Conclusion: SABR should be considered as a treatment option in GIST with bone metastasis.
