中文摘要:
      摘 要:[目的] 探讨碳离子放射治疗(carbon ion radiotherapy,CIRT)胰腺癌的临床疗效和安全性,以及影响患者生存的预后因素。[方法] 回顾性分析2020年1月至2025年8月期间CIRT治疗44例胰腺癌患者的临床资料。研究主要终点为总生存期,次要终点为急性不良反应。采用Kaplan-Meier法计算生存率并绘制生存曲线,采用Log-rank χ2检验进行单因素分析。[结果] 全组患者均顺利完成治疗,未发生Ⅲ级及以上急性不良反应,仅3例出现Ⅰ~Ⅱ级放射性十二指肠炎。全组患者随访时间 5~53个月,中位生存期为16个月(95%CI:14.59~NA)。CIRT治疗后1年、2年及3年生存率分别为71.06%、38.92%和25.94%。单因素分析显示:性别、日常生活能力评分、治疗前糖类抗原199水平及中性粒细胞与淋巴细胞比值是影响生存的显著预后因素(P<0.05)。[结论] CIRT具有良好的耐受性和安全性,即使在较高剂量下亦未增加严重不良反应,并能为胰腺癌患者带来较好的生存获益,需要在更大规模的研究中进一步验证。
英文摘要:
      Abstract:[Objective] To evaluate the clinical efficacy, safety, and prognostic factors affecting survival in pancreatic cancer patients treated with carbon ion radiotherapy (CIRT). [Methods] Clinical data of 44 CIRT-treated pancreatic cancer patients from January 2020 to August 2025 were retrospectively analyzed. The primary endpoint was overall survival(OS), and the secondary endpoint was acute adverse reaction. Survival rates were calculated using the Kaplan-Meier method, and univariate analysis was performed using the Log-rank χ2 test. [Results] All patients completed treatment successfully, with no grade ≥Ⅲ acute adverse reaction. Only 3 patients experienced grade Ⅰ~Ⅱ radiation-induced duodenitis. The follow-up period ranged from 5 to 53 months. The median OS was 16 months (95%CI: 14.59~NA). The 1-, 2-, and 3-year OS rates were 71.06%, 38.92%, and 25.94%, respectively. Univariate analysis identified sex, activities of daily living score, pre-treatment carbohydrate antigen 199 level, and neutrophil-to-lymphocyte ratio as significant prognostic factors for OS (P<0.05). [Conclusion] CIRT is well tolerated and safe in this cohort, without increasing severe adverse event, and provide promising survival outcomes for patients with pancreatic cancer. Further validation in larger studies is needed.
