Clinical Trial Summary
In this study, the investigators will perform endoscopic ultrasound-guided radiofrequency
ablation (EUS-RFA) treatment of left-sided adrenal tumours in patients with primary
aldosteronism (PA) and in patients with mild autonomous cortisol secretion (MACS). Four
different study groups will all receive EUS-RFA of left-sided adrenal tumours. Clinical and
biochemical outcome as well as procedural safety will be evaluated. In study patients with
verified lateralised aldosterone or cortisol overproduction to the left adrenal, outcome will
be compared with control groups performing conventional unilateral adrenalectomy.
Study group 1: PA patients with AVS-verified left sided lateralisation and a EUS-detectable
tumour in the left adrenal for EUS-RFA treatment.
Study group 2: PA patient with suspected left-sided overweight of aldosterone production and
a EUS-detectable tumour but without strict lateralisation of their aldosterone
overproduction, for EUS-RFA treatment as an aldosterone "debulking" procedure.
Study group 3: patients with MACS with AVS-verified lateralisation of cortisol overproduction
to the left adrenal and EUS-detectable tumour for EUS-RFA treatment Study group 4: patients
with MACS with bilateral adrenal tumours and verified bilateral overproduction of cortisol
for EUS-RFA treatment as a cortisol "debulking" procedure.
Description:
Primary aldosteronism (PA) is the most common cause of secondary hypertension, and is
associated with worse cardiovascular outcome than primary hypertension. Early diagnosis and
treatment is paramount to avoid excess morbidity and death. The two main forms of PA are
unilateral PA, often caused by an aldosterone-producing adenoma (APA), and bilateral PA.
Differentiation between unilateral and bilateral disease determines treatment options.
Adrenal vein sampling (AVS) is the recommended procedure to determine PA subtype, unilateral
or bilateral. For unilateral PA surgery with unilateral adrenalectomy is recommended
treatment. For PA without fulfilling lateralisation criteria, life-long medical treatment is
recommended.
Mild autonomous cortisol production (MACS) is present in 20-30% of all adrenal
incidentalomas, and is associated with the metabolic syndrome (hypertension, diabetes,
obesity and osteoporosis). Therefore these patients carry increased risk of developing
cardiovascular disease. Optimal treatment is debated, and based on the degree of MACS, degree
of metabolic complications, and the patient's own opinion. Unilateral adrenalectomy is an
option if the overproduction is unilateral, but in 15 % of cases, the overproduction is
bilateral, and treatment strategy even more troublesome.
The left adrenal is situated in near proximity to the stomach and is easily reached by
endoscopic ultrasound (EUS), and may be targeted for RFA, treating an aldosterone- or
cortisol-producing tumour only, and spearing the remaining adrenal. In this study we
introduce EUS-RFA as a new treatment option in the following patient groups:
Study group 1: PA patients with AVS-verified left sided lateralisation and a EUS-detectable
tumour in the left adrenal for EUS-RFA treatment.
Study group 2: PA patient with suspected left-sided overweight of aldosterone production and
a EUS-detectable tumour but without strict lateralisation of their aldosterone
overproduction, for EUS-RFA treatment as an aldosterone "debulking" procedure.
Study group 3: patients with MACS with AVS-verified lateralisation of cortisol overproduction
to the left adrenal and EUS-detectable tumour for EUS-RFA treatment Study group 4: patients
with MACS with bilateral adrenal tumours and verified bilateral overproduction of cortisol
for EUS-RFA treatment, as a cortisol "debulking" procedure.
For all study groups, if CT scan shows an adrenal nodule to the left adrenal, nodule size
must be < 40 mm and enhancement value must fulfill criteria for a benign adenoma. Patients
consenting to the EUS-RFA will have a EUS performed. If EUS of the left adrenal identifies an
adrenal nodule, a fine needle tissue sampling will be performed. Thereafter EUS-guided RFA
procedure of the tumour will be performed. After RFA treatment, the fine needle tissue
sampling will undergo morphological and functional characterisation, including application of
specific imaging mass cytometry for detection of aldosterone- or cortisol producing cells.
Clinical and biochemical outcome after EUS-RFA will be evaluated by the international
PASO-criteria (PA) or ENSAT/ECE criteria (MACS). In patients with lateralised PA or
lateralised MACS, clinical and biochemical outcome and postoperative hypoaldosteronism or
hypocortisolism will be compared with conventional unilateral adrenalectomy. Inn all
patients, procedural safety will be evaluated.
