Open versus minimally invasive surgery for suspected adrenocortical carcinoma.

Adrenocortical carcinoma (ACC) is a rare malignancy with a poor prognosis. Although laparoscopy has been widely adopted for management of benign adrenal tumors, minimally invasive surgery for ACC remains controversial. Retrospective analyses, frequently with fewer than one hundred participants, comprise the majority of the literature. High-quality data regarding the optimal surgical approach for ACC are lacking due to the rarity of the disease and the fact that determination of tumor type (e.g., adenoma or carcinoma) is determined after adrenalectomy, since adrenal tumors are generally not biopsied. While the benefits of minimally invasive surgery including lower intra-operative blood loss and decreased hospital length-of-stay have been consistently demonstrated, clinical equipoise for long-term survival and recurrence outcomes between open and minimally invasive adrenalectomy (MIA) remains. This review examines retrospective studies that directly compare patients with ACC who underwent either open or laparoscopic adrenalectomy, and considers these findings in the context of current guideline recommendations for surgical management of ACC.
