| Popis: | Background: Adrenalectomy is standard of care for phaeochromocytomas, but for bilateral phaeochromocytoma, the recommendations are inconsistent. However, large studies systematically investigating long-term outcomes for total adrenalectomies compared to those for patients with adrenal-sparing operations are lacking. Methods: A multi-center consortium-based registry was established to study clinical, genetic and surgical data in 623 patients with bilateral phaeochromocytomas. Findings: Of 623 patients, median age at diagnosis was 30 (range 3-79) years and 48% were female. Synchronous bilateral phaeochromocytomas were diagnosed in 396 patients and metachronousphaeochromocytomas in 227 (36%); interval to second operations were up to 40 (median 6) years. In 96% of tested patients germline mutations were detected in the genes RET (56%), VHL (34%), and others (10%). Of 849 operations, 385 (45%) surgeries in 326 patients were planned as adrenal-sparing which was successful in 251. 372 patients became steroid-dependent. Follow-up was up to 53 (median 11) years. Adrenal crises developed in 67 patients (18%) during follow-up, and 49 (13%) had manifestations of iatrogenic Cushing syndrome. Of the steroid-independent patients, 34 (14%) had developed another phaeochromocytoma within the remnant adrenal after up to 27, median 8 years, all treated with removal of the new phaeochromocytoma. Overall survival was mainly influenced by non-phaeochromocytoma comorbidities, whereas only 1% died of metastatic phaeochromocytoma. Cortical-sparing operations did not affect survival. Interpretation: Cortical-sparing operations avert lifelong steroid-dependency without affecting survival. Preoperative genetic testing is recommended even in unilateral phaeochromocytoma presentations to identify patients at heritable risk, to guide surgical approach, and inform for gene-specific extra-adrenal morbidities.
