研究目的:

本课题精准聚焦于肾细胞癌伴下腔静脉癌栓(RCC-IVCTT)患者术前健侧肾脏功能损害(pre-RD) 这一被长期忽视的临床现象。研究从明确的临床问题出发(pre-RD高发且预后差),通过前期临床研究首次系统定义了pre-RD,并发现其与下腔静脉梗阻密切相关;进而提出“癌栓导致健侧肾慢性淤血性损伤”的创新性科学假说,并利用独创的动物模型初步揭示了其潜在分子机制。在临床认知层面,挑战了“手术解除梗阻即可改善肾功能”的传统观念,揭示了RCC-IVCTT患者中普遍存在但未被充分认知的慢性淤血性肾损伤,推动临床对该并发症的重视;在科学研究层面,将“淤血性肾损伤”的研究范畴从经典的心衰领域,拓展至肿瘤性静脉梗阻这一全新情境,为理解慢性肾脏损伤提供了新的视角和模型。通过整合多组学数据与病理形态学评估,本研究旨在系统揭示静脉癌栓所致淤血性肾损伤的关键基因与信号通路,从而为临床早期诊断与靶向干预提供新的理论依据和潜在靶点。  

Objectives of Study:

This project precisely focuses on preoperative contralateral kidney functional impairment (pre-RD) in patients with renal cell carcinoma accompanied by inferior vena cava tumor thrombus (RCC-IVCTT), a long-neglected clinical phenomenon. Originating from a clear clinical problem (high incidence of pre-RD and its poor prognosis), this study systematically defines pre-RD for the first time through preliminary clinical research and identifies its close association with inferior vena cava obstruction. It further proposes an innovative scientific hypothesis, "tumor thrombus-induced chronic congestive injury to the contralateral kidney," and preliminarily explores the underlying molecular mechanisms using a novel animal model. At the clinical level, it challenges the traditional concept that "surgical removal of the obstruction can improve renal function," revealing the widespread yet underrecognized chronic congestive kidney injury in RCC-IVCTT patients and promoting greater clinical attention to this complication. At the scientific research level, it extends the scope of "congestive kidney injury" from the classic context of heart failure to the novel scenario of tumor-induced venous obstruction, offering new perspectives and models for understanding chronic kidney injury. By integrating multi-omics data with pathomorphological evaluation, this study aims to systematically elucidate the key genes and signaling pathways involved in congestive kidney injury induced by venous tumor thrombus, thereby providing new theoretical foundations and potential targets for early clinical diagnosis and targeted intervention.
