This study retrospectively reviewed the outcomes of patients with advanced hepatocellular carcinoma (HCC) receiving atezolizumab with bevacizumab (A + B) therapy at the Veterans Health Administration (VHA).
Patients with advanced HCC who received first-line systemic therapy with A + B at the VHA between December 1, 2019, and March 1, 2022, were selected from electronic medical records (EMR) using ICD-9 and ICD-10 codes. Abstractors reviewed the EMR of the patients from their index date of A + B initiation until death or their last VHA visit, with the study period ending on January 31, 2023. The chi-square test was used to compare rates, and the Mann-Whitney test was used to compare medians.
A total of 332 patients met the study criteria. The median age was 67 years; 99% were male, 63% were non-Hispanic Whites, 26% were Black, and 66% had an Eastern Cooperative Oncology Group performance status of ≥1. 84% had child Pugh score (CPS) class A, 16% had CPS classes B and C, 62% had a grade 2 albumin-bilirubin score, 56% had HCC caused by viral hepatitis, 80% had cirrhosis, and 67% had received prior local therapies. The 6-month progression-free survival (PFS) was 59%, while the 1-year PFS rate was 36%. Overall survival (OS) at 1-year was 52% in our study.
In real world, despite having similar PFS as the phase III IMbrave 150 trial, our OS at 12 months was lower (52% vs. 67%) because our study included a higher proportion of elderly patients with moderate liver dysfunction and a 40% non-White. This study provided real-world outcomes that differed from the study population in a pivotal trial.
本研究回顾性分析了退伍军人健康管理局(VHA)中接受阿替利珠单抗联合贝伐单抗(A+B)治疗的晚期肝细胞癌(HCC)患者的治疗结果。
从2019年12月1日至2022年3月1日期间在VHA接受A+B一线全身治疗的晚期HCC患者的电子病历(EMR)中,使用ICD-9和ICD-10编码进行筛选。提取人员回顾了患者从开始A+B治疗的索引日期直至死亡或最后一次VHA就诊时的EMR,研究期截止于2023年1月31日。采用卡方检验比较率,采用曼-惠特尼检验比较中位数。
共有332例患者符合研究标准。中位年龄为67岁;99%为男性,63%为非西班牙裔白人,26%为黑人,66%的东部肿瘤协作组体能状态≥1。84%的患者Child-Pugh评分(CPS)为A级,16%为B级和C级,62%的患者白蛋白-胆红素评分为2级,56%的患者HCC由病毒性肝炎引起,80%有肝硬化,67%曾接受过局部治疗。6个月无进展生存期(PFS)为59%,1年PFS率为36%。本研究中1年总生存期(OS)为52%。
在现实世界中,尽管PFS与III期IMbrave 150试验相似,但我们12个月时的OS较低(52%对67%),因为我们的研究纳入了更高比例的有中度肝功能不全的老年患者和40%的非白人患者。本研究提供了与关键试验中的研究人群不同的真实世界结果。
