Stereotactic body radiotherapy (SBRT) is an evolving treatment for the local management of pancreatic cancer (PC). The main purpose of this study is to report our initial experience in terms of local control (LC) and toxicity for PC patients treated with SBRT.
We conducted a retrospective review of patients treated with SBRT using abdominal compression (AC) or an end-expiratory breath-holding (EEBH) technique. The median prescribed dose was 35 Gy, delivered in five fractions. Toxicities were recorded using Common Terminology Criteria for Adverse Events (CTCAE) v5.0, and survival was estimated using the Kaplan-Meier method.
From 2017 to 2023, 17 PC patients were offered SBRT. Their median age was 69 years. The median follow-up from the date of diagnosis was 22.37 months. The overall survival (OS) was 94% at 1 year and 60.9% at 2 years. The progression-free survival (PFS) was 63.1% at 6 months and 56.1% at 9 months. The median OS was 26.3 months, and the median PFS was 20.6 months. The 6-month and 1-year LC rates were 71% and 50.8%, respectively.
We are successful in implementing the SBRT program at our centre. SBRT appears to be a promising treatment option for achieving LC with limited acute toxicities.
立体定向体部放疗（SBRT）是一种治疗胰腺癌（PC）的局部管理方法，正在不断发展。本研究的主要目的是报告我们采用 SBRT 治疗 PC 患者的局部控制（LC）和毒性的初步经验。
我们对采用腹部压缩（AC）或呼气末屏气（EEBH）技术进行 SBRT 的患者进行了回顾性研究。中位处方剂量为 35 Gy，分 5 次给予。采用 CTCAE v5.0 记录毒性，采用 Kaplan-Meier 法估计生存情况。
2017 年至 2023 年，我们为 17 例 PC 患者提供了 SBRT。他们的中位年龄为 69 岁。从诊断日期到中位随访时间为 22.37 个月。1 年的总生存率（OS）为 94%，2 年的 OS 为 60.9%。6 个月的无进展生存率（PFS）为 63.1%，9 个月的 PFS 为 56.1%。中位 OS 为 26.3 个月，中位 PFS 为 20.6 个月。6 个月和 1 年的 LC 率分别为 71%和 50.8%。
我们成功地在我们的中心实施了 SBRT 计划。SBRT 似乎是一种有前途的治疗选择，可实现 LC，且急性毒性有限。
