Analysis of adjuvant chemotherapy in patients undergoing curative-intent resection of localized adrenocortical carcinoma

Abstract

Background: Studies evaluating the role of adjuvant chemotherapy (ACT) in Adrenocortical Carcinoma (ACC) are limited due to its rarity. The objective of this study was to evaluate if ACT provides a survival benefit in patients who underwent curative-intent resection of localized ACC and to determine factors associated with receipt of ACT.

Methods: The National Cancer Data Base was queried to identify patients (2010-2016) with curative-intent resection of localized ACC (T1-T3, N0, M0).

Results: Of 577 patients with adrenalectomy, 389 (67%) had adrenalectomy alone, and 188 (33%) received ACT. Private insurance, lymphovascular invasion, stage II, and radiotherapy were predictors of ACT (P < 0.05). Advanced (T3) stage lymphovascular invasion, and being uninsured were associated with decreased OS (P < 0.05). There was no association between ACT and OS.

Conclusions: For patient who underwent curative-intent resection of localized ACC, there was no association between ACT and OS. Private insurance, lymphovascular invasion, stage II disease, and radiotherapy were associated with receipt of ACT.
