目的:我们的研究是研究牛磺内酯的影响,一种新型的抗肿瘤和抗血管生成药物,AGGF1,一种血管生成因子,诊断为肝细胞癌(HCC)的患者的血管生成模仿。
方法:在2021年5月至2022年12月期间,共有120例HCC患者来自我们医院的肿瘤和肝胆外科。所有患者均通过影像学或组织活检确认HCC诊断。患者的年龄从37岁到72岁,平均年龄64.29±4.58岁。将这些参与者平均分为两组:对照组和观察组,每人由60个人组成。对照组接受标准药物治疗,观察组给予牛磺内酯治疗。在被纳入研究之前,所有参与者或其法定代表人提供签署的知情同意书.通过问卷调查收集患者的人口统计信息。ELISA用于测量治疗后患者中VEGF和AGGF1的水平。Westernblot用于评估PDGF的蛋白表达,血管生成素,AGGF1利用MRI成像技术评估患者肿瘤血管的灌注特征。使用超声检查比较患者之间的肿瘤血管密度。我们还在无进展生存期和总生存期方面对两组进行了比较。
结果:两组患者一般资料差异无统计学意义(P>0.05)。值得注意的是,观察组VEGF和AGGF1水平明显低于对照组(P<0.05)。此外,PDGF的水平,血管生成素,与对照组相比,观察组AGGF1蛋白表达显著降低(P<0.05)。在肿瘤灌注方面,观察组肿瘤血管平均灌注量和最大灌注量均低于对照组(P<0.05)。此外,与对照组比较,观察组肿瘤血管峰值和到达时间延迟(P<0.05)。此外,观察组肿瘤血管密度明显低于对照组(P<0.05)。观察组患者的无进展生存期和总生存期均长于对照组(P<0.05)。
结论:在肝癌患者中,我们的研究强调了牛磺内酯治疗的潜在功效,因为它有效地抑制了血管生成因子和血管生成模拟,最终改善这些患者的预后。
OBJECTIVE: Our study was to investigate the impact of taurolactone, a novel anti-tumor and anti-angiogenic drug, on AGGF1, an angiogenic factor, and angiogenesis mimicry in patients diagnosed with hepatocellular carcinoma (HCC).
METHODS: A total of 120 HCC patients were enrolled from the Department of Oncology and Hepatobiliary Surgery at our hospital between May 2021 and December 2022. HCC diagnoses were confirmed through imaging or tissue biopsy for all patients. The age of patients ranged from 37 to 72 years, with an average age of 64.29 ± 4.58 years. These participants were divided equally into two groups: the control group and the observation group, each consisting of 60 individuals. While the control group received standard drug treatment, the observation group was administered taurolactone treatment. Before being included in the study, all participants or their legal representatives provided signed informed consent. Patient demographic information was collected through a questionnaire survey. ELISA was used to measure the levels of VEGF and AGGF1 in patients following treatment. Western blot was applied to assess the protein expression of PDGF, Angiopoietin, and AGGF1. MRI imaging technology was utilized to assess the perfusion characteristics of tumor blood vessels in patients. Tumor vessel density was compared between patients using ultrasonography. We also conducted a comparison between the two groups in terms of progression-free survival and overall survival.
RESULTS: General patient information between the two groups showed no significant differences (P > 0.05). Of note, the observation group exhibited greatly lower levels of VEGF and AGGF1 compared to the control group (P < 0.05). Moreover, the levels of PDGF, Angiopoietin, and AGGF1 protein expression were significantly reduced in the observation group compared to the control group (P < 0.05). In terms of tumor perfusion, the observation group displayed lower average and maximum perfusion volumes in tumor blood vessels compared to the control group (P < 0.05). Additionally, the observation group demonstrated delayed peak times and arrival times of tumor blood vessels in comparison to the control group (P < 0.05). Furthermore, the density of tumor blood vessels was notably lower in the observation group compared to the control group (P < 0.05). Patients in the observation group had longer progression-free survival and overall survival than the control group (P < 0.05).
CONCLUSIONS: In HCC patients, our study highlighted the potential efficacy of taurolactone treatment as it effectively inhibited angiogenic factors and angiogenesis mimicry, ultimately leading to an improved prognosis for these patients.
