Background: Adrenocortical carcinoma (ACC) is an aggressive cancer originating from steroidogenic cells within the adrenal cortex. Unfortunately, half of patients present with metastatic spread upon initial diagnosis, and there is no curative therapy for advanced disease. Genomic analysis has identified that the most aggressive subgroup of ACC patients have overlapping alterations in the WNT/β-catenin pathway and the p53/RB signaling pathway.Objecti...

Adrenocortical carcinoma (ACC) is a very severe endocrine malignancy with poor prognosis. While cancer immunotherapies have revolutionized the treatment of several cancer entities, the results of initial studies of different immune checkpoint inhibitors in ACC were heterogeneous and clinically substantial responses were observed only in a subset of patients. Expression of immune checkpoint molecules - programmed cell death 1 (PD-1), its ligand PD-L1 and cytotoxic T Lymphocytes...

Background: Adrenocortical carcinoma is a rare endocrine malignancy with poor prognosis and few treatment options in advanced disease. Immune checkpoint inhibitors (ICI) have been studied in few clinical trials with a limited number of patients in ACC. No real-life data are available so far. In the present study we aimed at evaluating treatment response and safety of ICI treatment in advanced ACC and identifying clinical, biochemical, histological and molecular markers for pre...
