在癌症治疗领域,肝细胞癌依然是一大挑战,手术切除是早期患者获得根治性治疗的重要选择,但术后高达50%-70%的复发率极大地限制了患者预后的改善。与此同时,随着免疫检查点抑制剂的应用,免疫治疗已成为肝癌治疗版图中的关键部分。然而,患者的治疗反应呈现出显著的异质性,如何精准识别哪些患者更可能从治疗中获益,哪些患者面临更高的复发风险,是临床上面临的紧迫问题。近年来的研究发现,一种由血小板、中性粒细胞和淋巴细胞计数计算得出的综合性指标——全身免疫炎症指数,因其整合了炎症与免疫状态,能更全面地反映肿瘤相关的炎症反应和宿主的免疫能力,被认为是肝癌的稳健预后指标。但对于SII高的高危患者群体,临床仍缺乏精确的风险评估工具。传统模型通常缺乏影像学特征的深度整合,也较少在免疫治疗场景下进行验证,其背后的生物学机制也尚不明确。针对这些不足,一项旨在解决这些难题的研究在《Journal of Hepatocellular Carcinoma》上发表了最新成果。
1 and FDR < 0.05), a total of 779 DEGs were identified, of which 275 were up-regulated and 504 were down-regulated. (B) KEGG enrichment bubble diagram, significant pathways include Cytokine-cytokine receptor interaction, IL-17 signaling pathway, etc. (C) GO circle diagram (BP / CC / MF): Enrichment items focused on antibacterial humoral immune response, chemotaxis / migration, myeloid leukocyte activation (BP), hemoglobin complex, monomer / homodimer ion channel complex (CC), oxygen carrier activity, ligand-gated ion channel activity, etc. (MF). (D) Immune infiltration analysis (quanTIseq): Tregs - quantiseq infiltration was significantly increased in the high-risk group (Wilcoxon P = 0.013). (E–K) drug sensitivity analysis (oncoPredict/calcPhenotype based on GDSC2 training): There were significant differences in the predictive sensitivity of the following drugs between the high and low risk groups-Teniposide-1809 (P = 0.032), Obatoclax-Mesylate-1068 (P = 0.037), AZD2014-1441 (P = 0.035), Wnt-C59-1622 (P = 0.057), Niraparib-1177 (P = 0.072), Talazoparib-1259 (P = 0.029) and AGI-6780-1634 (P = 0.031).">
