Methods A total of 217 patients who were diagnosed with decompensated hepatitis C cirrhosis and were admitted to The Third People’s Hospital of Kunming l from January, 2019 to December, 2022 were enrolled, among whom 63 patients who were readmitted within at least 1 year and had no portal hypertension-related complications were enrolled as recompensation group, and 154 patients without recompensation were enrolled as control group. Related clinical data were collected, and univariate and multivariate analyses were performed for the factors that may affect the occurrence of recompensation. The independent-samples t test was used for comparison of normally distributed measurement data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed measurement data between two groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. A binary Logistic regression analysis was used to investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis, and the receiver operating characteristic (ROC) curve was used to assess the predictive performance of the model. Results Among the 217 patients with decompensated hepatitis C cirrhosis, 63 (29.03%) had recompensation. There were significant differences between the recompensation group and the control group in HIV history (χ2=4.566, P=0.034), history of partial splenic embolism (χ2=6.687, P=0.014), Child-Pugh classification (χ2=11.978, P=0.003), grade of ascites (χ2=14.229, P<0.001), albumin (t=4.063, P<0.001), prealbumin (Z=-3.077, P=0.002), high-density lipoprotein (t=2.854, P=0.011), high-sensitivity C-reactive protein (Z=-2.447, P=0.014), prothrombin time (Z=-2.441, P=0.015), carcinoembryonic antigen (Z=-2.113, P=0.035), alpha-fetoprotein (AFP) (Z=-2.063, P=0.039), CA125 (Z=-2.270, P=0.023), TT3 (Z=-3.304, P<0.001), TT4 (Z=-2.221, P=0.026), CD45+ (Z=-2.278, P=0.023), interleukin-5 (Z=-2.845, P=0.004), tumor necrosis factor-α (Z=-2.176, P=0.030), and portal vein width (Z=-5.283, P=0.005). The multivariate analysis showed that history of partial splenic embolism (odds ratio [OR]=3.064, P=0.049), HIV history (OR=0.195, P=0.027), a small amount of ascites (OR=3.390, P=0.017), AFP (OR=1.003, P=0.004), and portal vein width (OR=0.600, P<0.001) were independent influencing factors for the occurrence of recompensation in patients with decompensated hepatitis C cirrhosis. The ROC curve analysis showed that HIV history, grade of ascites, history of partial splenic embolism, AFP, portal vein width, and the combined predictive model of these indices had an area under the ROC curve of 0.556, 0.641, 0.560, 0.589, 0.745, and 0.817, respectively. Conclusion For patients with decompensated hepatitis C cirrhosis, those with a history of partial splenic embolism, a small amount of ascites, and an increase in AFP level are more likely to experience recompensation, while those with a history of HIV and an increase in portal vein width are less likely to experience recompensation. -

大多数肝癌患者起病隐匿,诊断时已为晚期,失去根治性治疗机会,预后较差[1]。在全球Ⅲ期临床试验IMbrave 150中,阿替利珠单抗联合贝伐珠单抗(T+A方案)在不可切除肝细胞癌患者的一线治疗中的总生存期(overall survival,OS)和无进展生存期(progression-free survival,PFS)优于索拉非尼[2]。同样,在中国进行的多中心研究ORIENT-32表明,在不可切除的原发性肝癌患者中,信迪利单抗联合贝伐珠单抗类似物(双达方案)作为一线治疗的OS和PFS也显著优于索拉非尼[3]。基于上述研究,免疫检查点抑制剂联合抗血管生成治疗已成为不可切除肝癌的一线治疗标准,但客观缓解率仅有30%左右,远期生存率也有待提高[4-5]。
局部治疗对于控制病灶及改善长期生存均有较好疗效,目前立体定向放疗(stereotactic body radiotherapy,SBRT)已成为肝癌局部治疗的有效手段之一,与靶免方案的联合治疗也取得较好效果[6-7]。从机制上来看,放疗不仅可以造成肿瘤细胞DNA的直接损伤,还能导致肿瘤抗原释放,激活机体主动免疫,从而增强肿瘤免疫治疗效果[8]。抗血管生成治疗可以使肿瘤血管系统正常化,改善肿瘤微环境,从而提高放疗效果[9]。因此,SBRT联合双达方案的三联治疗从理论上可以改善不可切除肝癌患者的预后,但相关治疗效果、不良反应以及疗效预测指标鲜有报道。
本研究回顾性分析接受SBRT联合双达方案治疗的不可切除肝癌患者资料,评估预后及不良反应,探索预后预测指标,为该方案的治疗管理提供参考。
1. 资料和方法
1.1 研究对象
纳入2022年3月—12月在本中心放射治疗科接受SBRT联合双达方案治疗的不可切除肝癌患者42例。纳入标准:(1)经病理组织学确诊或符合临床诊断标准的原发性肝癌患者;(2)巴塞罗那分期为B或C期;(3)ECOG评分为0或1分;(4)治疗前基线AFP>40 mAU/mL;(5)根据改良实体瘤评价标准,至少有1处肝内可测量病灶。排除标准:(1)既往进行过抗肿瘤治疗;(2)双达方案治疗小于2个周期;(3)合并其他恶性肿瘤;(4)治疗后影像学或实验室数据缺失。
1.2 治疗方案
1.2.1 SBRT
本科室采用SBRT设备射波刀(美国Accuracy公司的VSI Cyberknife)。所有患者治疗前在CT引导下植入金标3~5枚,5~7天后于CT模拟机(somatom40排CT,德国Siemens公司)下行放疗定位。以CT模拟机平扫影像为基准图像,MR(Philips Ingenia MR-RT 3.0T,瑞士Royal Dutch Philips Electronics Ltd公司)增强影像为辅助图像,定位完成后将图像传至TPS系统(MultiPlan4.0系统,美国Accuracy公司)。放疗专科医生勾画相应肿瘤靶区和危及器官。大体肿瘤靶区基础上外扩3~5 mm为计划靶区,根据正常器官限量制定治疗计划,参照《AAPM TG101报告》[10]。SBRT剂量及分割模式主要取决于肝功能和正常器官剂量限制,也与病灶的大小、数量和位置等有关。给予处方剂量为36~50 Gy,分5~6次,连续照射。
1.2.2 双达方案
患者在完成放疗1周后接受信迪利单抗联合贝伐珠单抗治疗,具体剂量为:信迪利单抗200 mg,静脉滴注,每3周1次;贝伐珠单抗10 mg/kg,静脉滴注,每3周1次。双达方案一直使用到出现疾病进展或无法耐受的严重不良反应。
1.3 随访和评估
首次随访时间为治疗后6~8周,此后每6~8周随访1次。随访时检查血常规、肝功能、凝血功能、血清肿瘤标志物、上腹部增强CT或磁共振成像以及肺部CT,以评估肿瘤缓解。必要时进行PET-CT检查以确认是否肝外转移。主要终点为OS[定义为从SBRT开始日期至全因死亡日期或末次随访日期(2024年5月30日)的时间]以及PFS[定义为从SBRT开始日期至首次检测到影像学进展或全因死亡日期的时间]。次要终点为客观缓解率(objective response rate,ORR)和疾病控制率(disease control rate,DCR),根据mRECIST标准将肿瘤缓解分为完全缓解(complete remission,CR)、部分缓解(partial response,PR)、疾病稳定(stable disease,SD)和疾病进展(progressive disease,PD),并由2名经验丰富的放射科医生独立评价。ORR定义为获得CR+PR患者的百分比,DCR定义为获得CR+PR+SD患者的百分比。AFP应答定义为治疗后6~8周AFP下降大于50%。根据不良事件通用术语标准5.0版评估不良事件。
1.4 统计学方法
所有数据的统计分析使用SPSS 26.0或Graphpad Prism进行。通过Kaplan-Meier法和Log-rank检验估计生存率并进行比较;使用Cox比例风险模型估计HR和95%CI,在单变量模型中P<0.1的变量纳入多变量分析。P<0.05为差异有统计学意义。

在目前的临床诊疗中,免疫联合抗血管生成治疗已成为晚期肝细胞癌的一线标准方案,但ORR仅有30%左右,亟待提高[11-12]。随着放疗技术的进展,放疗不仅可导致肿瘤细胞DNA双链断裂,还能诱导免疫原性细胞死亡,刺激全身抗肿瘤免疫[13]。抗血管生成治疗可通过使肿瘤血管正常化,形成免疫友好的肿瘤微环境来增强放疗的功效[9]。此外,免疫治疗可以克服放疗导致肿瘤表面PD-L1表达增加、抑制性免疫细胞功能增强等负面作用,从而增强放疗的协同效率[14]。这为放疗联合免疫及抗血管生成治疗提供了坚实的理论依据。
既往回顾性研究分析了放疗联合靶免的治疗方案,Su等[15]研究发现,PD-1抑制剂与抗血管药物联合调强放疗的ORR为42.6%,Wang等[6]报道的SBRT联合仑伐替尼和PD-1抑制剂的ORR可达到63%。一项前瞻性多中心Ⅱ期临床研究显示,放疗联合双达方案的ORR为58.7%,中位PFS为13.8个月,中位OS为24.0个月[16]。与上述前瞻性研究不同,本研究放疗在双达方案之前,患者ORR为69%,与单独双达方案以及上述前瞻性研究相比均有提升,中位OS与前瞻性研究结果相当。在双达方案之前进行SBRT或许具有协同效应,可获得较好的局部缓解及生存结局,本研究为该三联疗法的可行性和安全性提供了临床证据。
本研究入组患者中有36例(85.8%)存在PVTT,通常与不良预后相关[17]。但由于PVTT细胞对辐射的敏感性较高,SBRT已被证明在控制PVTT方面疗效显著[18]。一方面,放疗使癌栓收缩有助于恢复部分门静脉血流,可改善肝功能;另一方面,PVTT的控制能消除部分侵入血流的肿瘤细胞,进而减少了血行转移,产生较好的肿瘤反应和生存结局[19]。除此之外,在双达方案之前使用SBRT可以有效降低肝脏肿瘤负荷,改善肝功能,提高患者对后续治疗的耐受性,从而接受更多周期的双达方案维持治疗,这可能是本组患者预后良好的原因之一。
在预后指标的探索方面,AFP是一种与肿瘤负荷和生物学行为相关的生物标志物,数十年来在肝癌领域发挥着重要作用[20]。当前指南推荐AFP与超声联合,用于肝癌高危人群的早期筛查[21]。此外,AFP易于在随访期间重复检测,可评估其动态变化来监测治疗效果[22]。目前关于AFP应答的临界值尚无定论,国内外研究多为主观定义。一项Meta分析显示,AFP应答的定义为AFP水平下降20%或50%所占比例居多,且该研究提示与AFP水平下降50%的临界值相比,AFP水平下降20%对OS和PFS的预测效果更好,但倾向于仅接受靶向治疗的患者[23]。Shao等[24]将早期AFP应答定义为治疗后4周下降超过20%,这与晚期肝癌免疫治疗较好的预后有关。另一项研究表明在接受T+A方案治疗的晚期肝癌患者中,治疗第6周时AFP较基线降低≥75%或升高≤10%的患者均具有较长的PFS及OS[25]。本研究参考入组患者AFP水平下降比例的中位值,将SBRT联合双达治疗后6~8周AFP水平下降>50%定义为AFP应答,多因素分析提示AFP应答是患者OS的独立影响因素。AFP应答可辅助影像学评估,有助于更好地识别该三联疗法中疗效显著的患者,并对疗效不佳患者及时调整治疗方案。但是,对于不同AFP初始值的肝癌患者,AFP应答的预测价值是否一致仍未知,且关于判断AFP应答的最佳时间窗目前亦无定论。在未来的探索中,需要更多高质量的前瞻性研究对AFP给予更多关注。
本研究也证实了SBRT联合双达方案治疗的安全性,双达方案治疗最常见的不良反应为蛋白尿、血小板减少、转氨酶升高、高血压和甲状腺功能减退等[3],与本研究不良反应相似,治疗期间未发生导致停药或死亡的不良事件。本研究中所采用的射波刀特有的呼吸追踪系统有效降低了照射过程中肝脏位移带来的肝损伤。另一方面以肿瘤为中心,剂量梯度衰减也使得周围组织所受照射剂量更低。总之,不良反应主要集中在1~2级,SBRT与双达方案联合产生协同毒性的可能性较小。
综上所述,SBRT联合双达方案治疗晚期肝癌可改善生存且安全性可控,治疗后6~8周AFP水平下降>50%与预后良好相关。但本研究为回顾性研究,样本量相对较少,未来仍需开展前瞻性的随机、对照、多中心临床研究,进一步验证结论。
