Despite advances in surgical, radiation and systemic therapy, the prognosis of pancreatic cancer remains poor. Most patients are not amendable to curative surgical resection at presentation. Chemo-radiotherapy is the standard of care for locally advanced pancreatic cancer, but its local control is poor. Stereotactic body radiotherapy (SBRT) is a viable therapeutic option to maximise local control with a tolerable side-effect profile. It enables precise delivery of high-dose radiation over a short period (typically 1-5 days) and leads to better local control, disease outcome, and symptom palliation. SBRT can also be applied in neoadjuvant, adjuvant, or re-irradiation treatment. We review the technology, clinical application, and future direction of SBRT for treatment of pancreatic cancer.

雖然手術、放療和全身治療有所進步,但胰腺癌的預後仍然很差。大多數患者在入院時無法耐受手術切除。化放療是局部晚期胰腺癌的標準治療方案,但局部控制較差。立體定向放射治療(SBRT)是能提供最大局部控制的可行選擇,而其副作用是可耐受的。它能夠在短時間內(通常為1-5天)精確地輸送高劑量輻射,並導致更好的局部控制、疾病結果和症狀緩解。SBRT也可用於新輔助治療、輔助治療或再照射治療。我們回顧SBRT治療胰腺癌的技術、臨床應用和未來發展方向。
