Abstract
Background
Posterior retroperitoneoscopic adrenalectomy is an appealing approach for patients
with hereditary pheochromocytoma and lends well to cortex preservation. We sought
to examine pheochromocytoma recurrence in patients with hereditary pheochromocytoma
in the era of posterior retroperitoneoscopic adrenalectomy and evaluate the predictors
of recurrence.
Methods
Patients with hereditary pheochromocytoma who underwent adrenalectomy for pheochromocytoma
between 1995 and 2020 with biochemical cure and follow-up >1 year were identified.
Recurrence was defined as plasma metanephrines above the upper limit of normal with
radiographic evidence of disease in the ipsilateral adrenal bed.
Results
Seventy-eight hereditary pheochromocytoma patients (median age = 32.4 years; 60.3%
women) underwent 114 adrenalectomies for pheochromocytoma. Of these patients, 40 had
multiple endocrine neoplasia type 2A (51.3%), 10 had multiple endocrine neoplasia
type B (12.8%), 17 had von Hippel-Lindau disease (21.8%), and 11 had neurofibromatosis
type 1 (14.1%). Thirty-eight adrenalectomies (33.3%) were performed before the introduction
of posterior retroperitoneoscopic adrenalectomy and 76 (66.7%) after. Cortical-sparing
technique was performed in 62 (54.4%) adrenalectomies, with no difference in its use
before and after posterior retroperitoneoscopic adrenalectomy introduction (P > .05). During a median follow-up of 80.7 months (interquartile range 43.4–151.2),
12 ipsilateral recurrences (10.5%) were identified. There was no difference in recurrence
before and after the introduction of posterior retroperitoneoscopic adrenalectomy
or by surgical technique or approach of the entire cohort (P > .05). Recurrence was more common in those with RET M918T mutation (23.5% vs 8.2%; P = .05). Patients with RET M918T mutations had a shorter recurrence-free survival (P = .013). On multivariate analysis, only RET M918T mutation was independently associated with an increased recurrence risk (hazard
ratio = 4.30; 95% confidence interval, 1.26–14.66; P = .019).
Conclusion
The introduction of posterior retroperitoneoscopic adrenalectomy did not influence
the recurrence rate after adrenalectomy for hereditary pheochromocytoma patients.
Patients with a RET M918T germline mutation are at increased risk for pheochromocytoma recurrence and
may benefit from initial total adrenalectomy.
