Summary

To validate the accuracy of 68Ga-Pentixafor PET/CT and adrenal venous sampling (AVS) in subtype diagnosis of PA/ACS patients with adrenal nodules, based on biochemical and clinical remission outcomes, and to determine whether the diagnostic accuracy of 68Ga-Pentixafor PET/CT is non-inferior to AVS.

Detailed description

This is a prospective, multicenter, randomized crossover trial. Patients with a confirmed diagnosis of primary aldosteronism (PA) or autonomous cortisol secretion (ACS) with adrenal nodules were prospectively enrolled. They were randomized to undergo 68Ga-Pentixafor PET/CT and adrenal venous sampling (AVS) in a crossover design for subtype diagnosis. The treatment strategy was determined based on the diagnostic results, with the primary endpoint being the biochemical complete remission rate at 6 months postoperatively. The study aims to compare the value of these two methods in the subtype diagnosis of PA.

Conditions

• Primary Aldosteronism
• Autonomous Cortisol Secretion

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	68Ga-Pentixafor PET/CT	Patients in the 68Ga-Pentixafor PET/CT group will first undergo 68Ga-Pentixafor PET/CT, followed by adrenal venous sampling (AVS). The subsequent treatment will be guided based on the diagnostic results. The diagnosis of unilateral PA was made if LISUVmax ≥1.50 or or unilateral functional adrenal tumor based on 68Ga-Pentixafor PET/CT
DIAGNOSTIC_TEST	AVS	Patients in the adrenal venous sampling (AVS) group will first undergo adrenal venous sampling (AVS), followed by 68Ga-Pentixafor PET/CT. The subsequent treatment will be guided based on the diagnostic results. The diagnosis of unilateral PA was made LI ≥ 4 or LI 2-4 with contralateral suppression or typical nodule on the dominant side by CT
