Surgery for recurrent adrenocortical carcinoma: A multicenter retrospective study

Adrenocortical carcinoma is a rare neoplasm with a high rate of recurrence. We studied the impact of surgery on the survival in recurrent adrenocortical carcinoma patients.

We performed a retrospective review of patients with recurrent adrenocortical carcinoma, managed in 5 French University Hospitals between 1980 and 2014. We compared surgery and medical management for ACC recurrence.

Fifty-nine patients were included, 46 of whom had an initial R0 resection. Twenty-nine patients underwent reoperation for recurrence, while 30 had nonoperative treatments. Operated patients had a greater median overall survival after recurrence than nonoperated patients (91 vs 15 months; P < .001). Patients operated on for local or distant recurrence had similar overall survival (110 vs 91 months; P = .81). In nonoperated patients, types of medical managements did not impact survival. Surgery for recurrence (P = .037) and a disease-free interval between initial resection and recurrence >12 months (P = .059) were both prognostic factors for improved survival, whereas age, stage, and tumor size (P ≥ .2 each) were not. A Ki67 <25% tended to be associated with better overall survival (P = .051).

Both surgery for recurrence and disease-free interval between the initial resection of an adrenocortical carcinoma and recurrence >12 months are associated with better overall survival.
