BACKGROUND: Adrenocortical carcinoma (ACC) is a rare malignancy that carries a poor prognosis. There has yet to be a large Australian series that documents the characteristics of ACC and there are a paucity of data on management and the long-term outcomes. We sought to provide a unique insight into the management of ACC in Australia as well as to identify factors associated with prognosis and survival.
METHODS: A multivariate analysis of a cohort of patients identified with ACC between 1998 and 2013 was undertaken. Recurrence-free survival (RFS) and overall survival (OS) were assessed as the main outcome measures and correlated with multiple clinical variables in order to identify prognostic markers.
RESULTS: Of the 104 patients identified, a total of 98 patients with complete clinical and outcome data were included in the study. Median OS was 56 months, with the 5-year survival being 48 % (95 % confidence interval 36-59). On multivariate analysis, age ≥50 years, metastases at presentation, and evidence of extra-adrenal invasion were found to be statistically associated with reduced OS. RFS was analyzed in patients without metastases. On multivariate analysis, extra-adrenal invasion and no preoperative endocrine investigations were found to be statistically significant poor prognostic factors, with a non-significant trend for higher individual surgeon volume to be associated with improved resection margins and RFS.
CONCLUSIONS: We present clinical outcomes and prognostic factors for patients with ACC in a landmark Australian series. We suggest that management in a specialized tertiary endocrine and/or surgical oncology unit is more likely to lead to improved outcomes.
