Immunity in adrenocortical carcinoma patients – interplay between anti-cancer immunity and steroid hormones

Sbiera Silviu , Dexneit Thomas , Sbiera Iuliu , Schreiner Jochen , Ronchi Cristina L. , Kroiss Matthias , Fassnacht Martin

Adrenocortical carcinoma (ACC) is one of the most aggressive endocrine malignancies. By applying a ‘multiple omics’ approach, we recently identified two distinct subgroups of ACC patients, a good prognosis “immune” and bad prognosis “steroid” phenotype.We hypothesized that the steroid phenotype is associated with glucocorticoid-induced suppression that can be ‘rescued’ by reactivating the immune system using immune...

Immune infiltrate and PD-1 / PD-L1 expression in adrenocortical carcinoma: who can predict patients´ outcome?

Landwehr Laura-Sophie , Sbiera Iuliu , Schreiner Jochen , Weigand Isabel , Kroiss Matthias , Fassnacht Martin , Sbiera Silviu

Context: Adrenocortical carcinoma (ACC) are endocrine malignant neoplasms associated with severe aggressiveness. Tumour-related glucocorticoid excess occurs in 60% of patients and is associated with poor prognosis. First clinical trials using immune checkpoint inhibitors are quite unsatisfactory and treatment advancements are urgently needed.Recently, we characterized tumour-infiltrating lymphocytes (TILs) in ACC and identified the detrimental dependency...

JIL-O: Establishment of a new steroidogenic human adrenocortical carcinoma cell line

Landwehr Laura-Sophie , Jochen Schreiner , Herterich Sabine , Appenzeller Silke , Fassnacht Martin , Kroiss Matthias , Weigand Isabel

Adrenocortical carcinoma (ACC) is a rare malignancy with heterogeneous but dismal prognosis and despite numerous efforts to improve patient care, effective treatment options are still lacking. ACC in vitro research faces for decades one major obstacle - the unavailability of different ACC cell line models. Here, we present a newly established human ACC cell line that was directly transferred to and now proliferates in cell culture. JIL-O cell line was derived from a p...

Characterization of cell death induced by mitotane in adrenocortical carcinoma cells

Weigand Isabel , Schreiner Jochen , Rohrig Florian , Kiseljak-Vassiliades Katja , Hofner Kerstin , Kendl Sabine , Fassnacht Martin , Sbiera Silviu , Kroiss Matthias

Background: Mitotane is the only drug approved for treatment of adrenocortical carcinoma (ACC). We have found that mitotane leads to endoplasmic reticulum stress and decreased viability in ACC cells. It is not known by which downstream mechanisms cell death is induced by mitotane.Aim: To characterize the mechanisms underlying cell death resulting from mitotane treatment in ACC cells.Methods: Lipid peroxidation in the ACC cell line ...

Steroid hormones and cancer immunity - insights into adrenocortical carcinoma

Landwehr Laura-Sophie , Dexneit Thomas , Herterich Sabine , Sbiera Iuliu , Schreiner Jochen , Kroiss Matthias , Fassnacht Martin , Sbiera Silviu

Context: Adrenocortical carcinoma (ACC) are endocrine malignant neoplasms associated with severe aggressiveness. By applying of ‘multiple omics’ approach, we recently categorized ACC patients based on their steroidogenic activity and expression of immune activation marker, which is along with prognosis; an ‘immune’ phenotype with good and a ‘steroid’ phenotype with bad outcome.Hypothesis: Our central hypothesis focuses on th...

Chortis Vasileios , Nijman Thomas , Bancos Irina , Gilligan Lorna C , Taylor Angela E , Ronchi Cristina L , O'Reilly Michael W , Schreiner Jochen , Asia Miriam , Riester Anna , Terzolo Massimo , Libe Rosella , Quinkler Marcus , Canu Letizia , Paiva Isabel , Bugalho Maria J , Kastelan Darko , Dennedy M Conall , Sherlock Mark , Ambroziak Urszula , Vassiliadi Dimitra , Bertherat Jerome , Beuschlein Felix , Fassnacht Martin , Deeks Jonathan J , Biehl Michael , Arlt Wiebke

Objective: Urine steroid metabolomics, combining mass spectrometry-based steroid profiling and machine learning, has been described as a novel diagnostic tool for detection of adrenocortical carcinoma (ACC). This proof-of-concept study evaluated the performance of urine steroid metabolomics as a tool for post-operative recurrence detection after microscopically complete (R0) resection of ACC.Methods: 135 ACC patients from 14 clinical centres provided pos...
