Target disease:

Pheochromocytoma (PHEO) coexisting ipsilaterally with primary aldosteronism (PA)

研究类型:

观察性研究

Study type:

Observational study

研究所处阶段:

Study phase:

N/A

研究设计:

病例研究 

Study design:

Case study 

研究目的:

1. 明确同侧 PHEO 与 APN 共存的组织学与空间分布特征。 2. 分析不同区域的突变谱差异,评估是否存在共享突变或独立起源。 3. 揭示 PHEO(尤其 VHL 突变)是否通过 CXCL12/VEGF/HIF-2α 等旁分泌机制促进 APN 的形成。 4. 利用细胞实验构建机制模型,为此类罕见并存疾病提供病理生理依据。  

Objectives of Study:

1. Characterize the histological and spatial distribution features of coexisting ipsilateral PHEO and APN. 2. Analyze differences in mutation profiles across distinct regions to assess whether shared mutations exist or if independent origins are present. 3. Reveal whether PHEO (particularly VHL mutations) promotes APN formation through paracrine mechanisms such as CXCL12/VEGF/HIF-2α. 4. Develop mechanistic models using cellular experiments to provide pathophysiological rationale for this rare coexisting disease.
