Pheochromocytoma and paraganglioma (PPGLs) are neuroendocrine tumors with diverse clinical presentations. PPGLs can be sporadic but often are associated with various syndromes, which can have variable clinical presentations. A thorough workup is therefore critical for staging, treatment, and follow-up. Imaging is an essential part of the workup and diagnosis of PPGLs.
Improvements in cross-sectional imaging with radionuclides have increased specificity and sensitivity for identifying and treating PPGLs. Furthermore, a variety of targets on PPGLs has allowed for optimal imaging with radionuclides that can be used for staging and treatment. Currently, radionuclides are being evaluated for staging and treatment of PPGLs. Developing novel radionuclides that can identify disease sites and target them simultaneously provides a potential for improving survival and outcomes in patients with PPGLs. Given the clinical diversity among PPGLs, expanding the therapeutic arsenal against locally advanced or metastatic PPGLs can allow clinicians to evaluate and treat PPGLs thoroughly.
嗜铬细胞瘤和副神经节瘤(PPGL)是具有多种临床表现的神经内分泌肿瘤。PPGL 可以是散发性的,但常与各种综合征相关,这些综合征可能有不同的临床表现。因此,彻底的检查对于分期、治疗和随访至关重要。影像学是 PPGL 检查和诊断的重要组成部分。
随着放射性核素的横断面成像技术的进步,其在识别和治疗 PPGL 方面的特异性和敏感性都有所提高。此外,PPGL 上的各种靶点使得放射性核素的最佳成像成为可能,从而可用于分期和治疗。目前,放射性核素正在评估用于 PPGL 的分期和治疗。开发能够同时识别疾病部位并靶向它们的新型放射性核素,为提高 PPGL 患者的生存率和预后提供了可能。鉴于 PPGL 的临床表现多样化,扩大针对局部晚期或转移性 PPGL 的治疗武器库,可以让临床医生更全面地评估和治疗 PPGL。
