Cortical-sparing adrenalectomy for patients with bilateral pheochromocytoma.
BACKGROUND: Bilateral pheochromocytomas are common in patients with multiple endocrine neoplasia type 2 (MEN 2) and von Hippel-Lindau disease ( VHL). In an effort to avoid long-term steroid dependence and Addisonian crisis, we have performed cortical-sparing adrenalectomy in this patient population. METHODS: Retrospective chart review was completed for patients with MEN 2- or VHL-related pheochromocytomas who underwent laparotomy at our institution for intended cortical-sparing adrenalectomy between June 1965 and March 1995. RESULTS: Fifteen patients (MEN 2A [10], MEN 2B [2], VHL [3]) underwent laparotomy for cortical-sparing adrenalectomy. None of the tumors were malignant. Cortical-sparing adrenalectomy was possible in 14 (93%). Thirteen of these 14 patients (93%) had normal postoperative plasma cortisol measurements and did not require steroid hormone supplementation. At a median follow-up of 138 months, two patients had died of metastatic medullary thyroid cancer, no patient had suffered Addisonian crisis, and three patients (21%) had recurrent pheochromocytomas (at 118, 176, and 324 months after operation). The remaining nine patients were alive without pheochromocytomas. CONCLUSIONS: Cortical-sparing adrenalectomy can be performed successfully in MEN 2 or VHL patients with bilateral pheochromocytomas, avoiding chronic steroid hormone replacement and the risk of Addisonian crisis in most patients. Long-term follow-up is necessary because recurrence may develop many years after operation.[1]References
