摘要: 目的 探索应用改良CARG模型指导中国老年肿瘤患者抗癌药物剂量调整。方法 前瞻性收集北京协和医院肿瘤内科2022年9月1日至2023年10月29日收治的年龄≥65岁的实体肿瘤患者的临床资料,对其进行老年综合评估(CGA)和CARG评分,根据CARG评分分为低、中、高风险组,结合治疗目的(根治性、姑息性)给予相应比例的抗癌药物减量,记录所有患者的抗癌(化疗、靶向和免疫治疗)生存数据和不良反应。采用费舍尔精确检验对比CARG评分指导调整剂量组(试验组)和医生经验性调整剂量组(对照组)不良反应发生率的关系。采用受试者操作特征曲线(ROC)分析CARG模型对抗癌药物严重不良反应的预测价值。结果 共纳入166例年龄≥65岁老年实体肿瘤患者,中位年龄71岁(65~90岁),78.3%为男性,68.7%为消化道肿瘤,69.3%为Ⅳ期。试验组95例,其中CARG评分低、中、高风险组人数分别为24例(25.3%)、51例(53.7%)和20例(21.0%),对照组71例。随访截止于2024年12月31日,81例患者疾病进展,10例死亡。试验组和对照组的总体不良反应发生率分别为92.6%和94.4%,其中≥3级不良反应发生率分别为45.3%和43.7%,两组之间均无显著统计学差异。结论 改良CARG模型指导剂量调整策略达到了与经验性剂量调整相当的安全性,符合老年肿瘤患者的个体化治疗理念,优化了老年肿瘤治疗的决策工具。

Abstract: Objective To evaluate the clinical value of a modified Cancer and Aging Research Group(CARG) model in guiding anticancer drug dose adjustments for elderly cancer patients in China. Methods This prospective study enrolled patients aged ≥65 years with solid tumors at the Department of Oncology, Peking Union Medical College Hospital from September 1, 2022 to October 29, 2023. All patients underwent comprehensive geriatric assessment(CGA) and CARG risk scoring, and were stratified into low-, intermediate-, and high-risk groups. Anticancer drug doses(including chemotherapy, targeted therapy or immunotherapy) were reduced proportionally based on CARG risk stratification and treatment intent(curative vs. palliative). Treatment outcomes and adverse events(AEs) were recorded regularly. Fisher's Exact Test compared AE incidence between the CARG-guided dose adjustment group(experimental) and the physician-experience-guided dose adjustment group(control). Receiver operating characteristic(ROC) curve analysis was used to assess the predictive value of the CARG model for severe toxicity. Results Among 166 enrolled patients(median age: 71 years[range: 65-90]; 78.3% were male; 68.7% had gastrointestinal cancers; 69.3% had stage Ⅳ), 95 were assigned to the experimental group(CARG low-risk: 24[25.3%], intermediate-risk: 51 [53.7%], high-risk: 20[21.0%]) and 71 were included into the control group. By December 31, 2024, 81 patients experienced disease progression and 10 patients died. Overall AE rates was 92.6% in the experimental group and 94.4% in the control group, while grade ≥3 AEs were recorded in 45.3% vs. 43.7%, respectively(both P>0.05). Conclusions The modified CARG model-guided dose adjustment strategy achieved comparable safety to empirical dose adjustment, which is in line with the individualized treatment paradigm for elderly cancer patients, representing a structured framework for optimizing therapeutic decision-making in geriatric oncology.
