BACKGROUND: Adrenocortical carcinoma (ACC) is an aggressive, deadly malignancy. Resection remains the primary treatment; however, there is conflicting evidence regarding the optimal approach to and extent of surgery and the role of adjuvant therapy. We evaluated the impact of surgical technique and adjuvant therapies on survival in non-metastatic ACC.
METHODS: We performed a retrospective cohort study of subjects who underwent surgery for non-metastatic ACC between 2010 and 2019 utilizing the National Cancer Database. The primary outcome was overall survival. Cox proportional hazards models were developed to identify associations between clinical and treatment characteristics and survival.
RESULTS: Overall, 1175 subjects were included. Their mean age was 54 ± 15 years, and 62% of patients were female. 67% of procedures were performed via the open approach, 22% involved multi-organ resection, and 26% included lymphadenectomy. Median survival was 77.1 months. Age (hazard ratio [HR] 1.019; p < 0.001), advanced stage (stage III HR 2.421; p < 0.001), laparoscopic approach (HR 1.329; p = 0.010), and positive margins (HR 1.587; p < 0.001) were negatively associated with survival, while extent of resection (HR 1.189; p = 0.140) and lymphadenectomy (HR 1.039; p = 0.759) had no association. Stratified by stage, laparoscopic resection was only associated with worse survival in stage III disease (HR 1.548; p = 0.007). Chemoradiation was only associated with improved survival in patients with positive resection margins (HR 0.475; p = 0.004).
CONCLUSION: Tumor biology and surgical margins are the primary determinants of survival in non-metastatic ACC. Surgical extent and lymphadenectomy are not associated with overall survival. In advanced disease, the open approach is associated with improved survival.
