Adrenocortical Carcinoma: a Therapeutic Challenge - 44 Cases from a Single Tertiary Care Center in India.

This study was conducted among patients with adrenocortical carcinoma (ACC) to analyze their clinico-pathological profile, management outcomes, and risk factors for local recurrence, systemic metastasis, and survival. The data of patients with ACC who were managed at a single institution between January 2004 and December 2016 was retrospectively collected and analyzed using STATA 13.1. Forty-four patients with a diagnosis of ACC were included in the study. The mean age at presentation was 38.5 ± 14.6 (9-74) with a male preponderance. Functioning tumors represented 59.1% (n = 26), cortisol being the most common hormone secreted. Forty patients (90.9%) underwent surgery, 14 (35%) of whom required an en bloc resection of adjacent organs. Fifteen (37.5%) received radiation (RT) to the postoperative bed while chemotherapy and mitotane were administered in 12 (27.3%) and 9 (20.5%) respectively. The mean follow-up was 34.3 ± 32.7 months. Twelve (30%) patients developed local recurrence, 21 (55.3%) had systemic metastasis, and 15 (34.1%) expired. The mean 1-year and 5-year overall survival rates were 77% and 65.7% respectively. On multivariate analysis, patients with ENSAT stage III/IV were significantly associated with local recurrence (p = 0.011) and metastasis (p = 0.037). Age > 50 (p = 0.003) and ENSAT III/IV (p = 0.017) were significantly associated with mortality on univariate analysis but not on multivariate analysis. In our study population, patients presented at a younger age with a male preponderance. Ninety percent underwent surgery, a subset (35%) requiring resection of adjacent organs to ensure R0 resection. Patients presenting at ENSAT stage I/II have better outcomes. © Indian Association of Surgical Oncology 2021.
