中文摘要
近期研究表明,血小板可能通过支持肿瘤生长和增加化疗耐药性,在胰腺癌进展中发挥作用。本研究旨在利用血小板相关基因风险评分构建胰腺癌预后模型。从公共数据库中筛选出预后相关血小板相关基因(PRGs),并进行聚类分析。我们研究了基于不同PRG分子亚型的胰腺癌的微环境特征和基因突变模式。采用LASSO-Cox回归分析构建了基于PRGs的预后模型。此外,我们还分析了风险评分与肿瘤临床特征及药物敏感性之间的相关性。研究识别出两种分子亚型,即聚类C1和C2。与聚类C1相比,聚类C2与更差预后相关。C1组在活化CD8+ T细胞、中枢记忆CD4+ T细胞和自然杀伤T细胞方面评分较高。C2组表现出更高的基因突变频率。我们建立并验证了一种新的胰腺癌预后预测模型及血小板相关基因风险评分。该风险评分与T分期、N分期和肿瘤分级呈正相关,且与其他临床因素相比具有显著的预后价值。总之,我们开发了一种聚焦于血小板参与胰腺癌的新型预后预测模型,为未来药物疗法和临床预后评估提供了潜在益处。

Recent studies have indicated that platelets may play a role in the advancement of pancreatic cancer by supporting tumor growth and increasing resistance to chemotherapy. This study aims to develop a prognostic model for pancreatic cancer using a platelet-related gene risk score. Prognostic platelet-related genes (PRGs) were identified from public databases and analyzed using cluster analysis. We investigated the microenvironment signatures and gene mutation patterns across different PRG-based molecular subtypes of pancreatic cancer. A prognostic model based on PRGs was developed using LASSO-Cox Regression Analysis. Additionally, we examined the correlation between the risk score and tumor clinical characteristics, as well as drug sensitivity. Two molecular subtypes, cluster C1 and C2, were identified. Cluster C2 was associated with a poorer prognosis compared to Cluster C1. The C1 group exhibited higher scores for activated CD8+ T cells, central memory CD4+ T cells, and natural killer T cells. The C2 group demonstrated a higher frequency of gene mutations. We established and validated a novel prognostic prediction model and platelet-related gene risk score for pancreatic cancer. The risk score was positively correlated with T stage, N stage, and tumor grade, and it presented a significant prognostic value compared to other clinical factors. In conclusion, a novel prognostic prediction model focusing on platelet involvement in pancreatic cancer has been developed, offering potential benefits for future drug therapies and clinical prognostic assessments.
