Purpose: Open adrenalectomy (OA) remains the gold standard of surgical therapy for adrenocortical carcinoma, while the role of laparoscopic approach is controversial. We aim to explore the influence of surgical approaches on the oncologic prognosis of adrenocortical carcinoma by comparing the short-term outcomes of patients undergoing OA with those undergoing laparoscopic adrenalectomy (LA).
Patients and methods: We retrospectively analyzed the baseline characteristics, perioperative data and short-term prognosis of 42 patients diagnosed with stage I–III adrenocortical carcinoma, receiving OA (n=22) and LA (n=20) as primary therapy. The primary end point was the first recurrence.
Results: OA group had larger mean maximum diameter of tumor (10.1±3.6 versus 6.3±2.2 cm) and lesser benefits in operative time, bleeding loss and postoperative hospital stay than laparoscopic group. Mean disease-free survival (DFS) of OA was 44.8±35.1 months, which was longer than 17.5±10.4 months of LA, and the rate of 2-year DFS after primary surgery in the open group was higher than in the laparoscopic group (61.1% versus 21.4%, respectively). Rates of 1- and 3-year DFS showed no significant difference. All patients undergoing LA (11/11) showed local recurrent lesions at the first time of recurrence, while 5 of 13 patients undergoing OA did not show local recurrence (P=0.03).
Conclusion: OA for adrenocortical carcinoma is superior to laparoscopic approach in terms of DFS and rate of 2-year DFS, in spite of the larger maximum diameter of tumors and lesser benefit during perioperation. After LA, patients are more likely to show local recurrent lesions at the first time of relapse.
