BACKGROUND/AIM: There is no known report regarding the relationship of atezolizumab plus bevacizumab (Atez/Bev) treatment with muscle volume loss (MVL) in unresectable hepatocellular carcinoma (u-HCC) patients. This study aimed to elucidate the clinical relationship between MVL and Atez/Bev.
MATERIALS/METHODS: From September 2020 to December 2021, 229 u-HCC patients treated with Atez/Bev and with muscle volume data obtained by computed tomography at the baseline available were analyzed (median age, 74 years; males, 186 (81.2%); ECOG PS 0/1, 221 (96.5%); HCV:HBV:alcohol:others = 81:33:40:75; Child-Pugh A, 212 (92.6%); modified albumin-bilirubin (mALBI) grade 1:2a:2b = 79:60:90; BCLC 0:A:B:C = 1:24:87:117; median observation period, 6.8 months). Japan Society of Hepatology criteria were used for definition of MVL and prognostic factors were retrospectively evaluated.
RESULTS
Multivariate Cox-hazard analysis of prognostic factors for progression-free survival (PFS) showed elevated alpha-fetoprotein (AFP) (≥100 ng/mL) (HR 1.848, 95% CI 1.264-2.702, = 0.002), mALBI grade (≥2a) (HR 1.563, 95% CI 1.035-2.359, = 0.034), and MVL (HR 1.479, 95% CI 1.020-2.144, = 0.039) as significant factors. For overall survival (OS), significant factors included elevated AFP (≥100 ng/mL) (HR 3.564, 95% CI 1.856-6.844, < 0.001), mALBI grade (≥2a) (HR 3.451, 95% CI 1.580-7.538, = 0.002), and MVL (HR 2.119, 95% CI 1.150-3.904, = 0.016). Patients with MVL (MVL group, = 91) showed worse PFS than those without (non-MVL group, = 138) (median PFS 5.3 vs. 7.6 months, = 0.025), while the MVL group showed worse OS ( = 0.038), though neither reached the median survival time.
CONCLUSION
MVL may be a clinical factor related to poor prognosis in patients receiving Atez/Bev treatment for u-HCC.
背景/目的：目前尚无关于阿替利珠单抗联合贝伐单抗（阿替利珠单抗/贝伐单抗）治疗与不可切除肝细胞癌（u-HCC）患者肌肉量减少（MVL）之间关系的报道。本研究旨在阐明MVL与阿替利珠单抗/贝伐单抗之间的临床关系。
材料/方法：对2020年9月至2021年12月期间接受阿替利珠单抗/贝伐单抗治疗且基线时有通过计算机断层扫描获得的肌肉量数据的229例u-HCC患者进行分析（中位年龄74岁；男性186例（81.2%）；东部肿瘤协作组体能状态0/1分，221例（96.5%）；丙型肝炎病毒：乙型肝炎病毒：酒精：其他=81:33:40:75；Child-Pugh A级，212例（92.6%）；改良白蛋白-胆红素（mALBI）分级1:2a:2b=79:60:90；巴塞罗那临床肝癌（BCLC）0:A:B:C级=1:24:87:117；中位观察期6.8个月）。采用日本肝脏学会标准定义MVL，并对预后因素进行回顾性评估。
结果
无进展生存期（PFS）预后因素的多因素Cox风险分析显示，甲胎蛋白（AFP）升高（≥100 ng/mL）（风险比[HR]1.848，95%置信区间[CI]1.264-2.702，P=0.002）、mALBI分级（≥2a）（HR 1.563，95%CI 1.035-2.359，P=0.034）和MVL（HR 1.479，95%CI 1.020-2.144，P=0.039）为显著因素。对于总生存期（OS），显著因素包括AFP升高（≥100 ng/mL）（HR 3.564，95%CI 1.856-6.844，P<0.001）、mALBI分级（≥2a）（HR 3.451，95%CI 1.580-7.538，P=0.002）和MVL（HR 2.119，95%CI 1.150-3.904，P=0.016）。有MVL的患者（MVL组，n=91）的PFS比无MVL的患者（非MVL组，n=138）更差（中位PFS 5.3个月对7.6个月，P=0.025），而MVL组的OS更差（P=0.038），尽管两组均未达到中位生存时间。
结论
MVL可能是接受阿替利珠单抗/贝伐单抗治疗的u-HCC患者预后不良的临床相关因素。
