PD-1 and PD-L1 immune checkpoint expression - the prognostic impact on adrenocortical carcinoma

Landwehr Laura-Sophie , Sbiera Iuliu , Altieri Barbara , Remde Hanna , Kircher Stefan , Sbiera Silviu , Kroiss Matthias , Fassnacht Martin

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) and its ligand PD-L1 - has been shown to pred...

Clinical relevance of targeted sequencing in paraffin-embedded samples for prognostic classification of adrenocortical carcinoma

Lippert Juliane , Dischinger Ulrich , Appenzeller Silke , Prete Alessandro , Kircher Stefan , Skordilis Kassiani , Elhassan Yasir , Altieri Barbara , Fassnacht Martin , Ronchi Cristina

Adrenocortical carcinoma (ACC) is a rare malignant tumour with heterogeneous outcome. Prognostic classification relies on individual clinical/histopathological parameters that have limited performance. Recent studies proposed the use of selected DNA-based biomarkers to improve prognostication of ACC. Aim of the study was to perform a comparative analysis of DNA-based biomarkers (BM) for prognostic assessment of ACC by evaluating their added value to the established prognostic ...

Is there an epithelial to mesenchymal transition (EMT) in adrenocortical tumours?

Sbiera Iuliu , Kircher Stefan , Feuchtinger Annette , Höfner Kerstin , Karl Walch Axel , Fassnacht Martin , Kroiss Matthias , Sbiera Silviu

Introduction: Adrenocortical carcinoma (ACC) is an aggressive tumour with unsatisfactory treatment options in advanced disease. Activation of epithelial to mesenchymal transition (EMT) has been described as causative of metastatic spread in human cancers. New drugs were developed targeting EMT with a focus on FGF/FGFR signalling. We here asked whether EMT is relevant in ACC.Methods: We analysed 6 normal adrenal glands (NAG), 40 adrenocortical adenomas (A...

New cancer drug targets identified in adrenocortical carcinoma through gene expression profiling

Liang Raimunde , Weigand Isabel , Altieri Barbara , Kircher Stefan , Steinhauer Sonja , Sbiera Silviu , Kroiss Matthias , Rosenwald Andreas , Fassnacht Martin , Ronchi Cristina

Adrenocortical carcinomas (ACC) are associated with heterogeneous prognosis and limited treatment options for advanced stages. Until now no efficient targeted therapies have been identified. This study aims to identify possible new molecular drug targets for a future personalized therapeutic approach. We isolated good quality RNA from 40 formalin-fixed paraffin-embedded tumor samples (33 from primary surgery, 5 from local recurrences and 2 from distant metastasis) of ACC patie...

Prognostic role of targeted methylation analysis in formalin-fixed paraffin-embedded samples of adrenocortical carcinoma

Lippert Juliane , Altieri Barbara , Morrison Breanna , Steinhauer Sonja , Smith Gabrielle , Lorey Antonia , Hanna Urlaub , Kircher Stefan , Sitch Alice J , Fassnacht Martin , Ronchi Cristina

Adrenocortical carcinoma (ACC) is a rare and aggressive endocrine neoplasia with heterogeneous molecular background and clinical outcome. Previous studies identified hypermethylation in specific genes to be associated with poor prognosis. Here, we aimed to investigate the role of methylation pattern for prognostic stratification of patients with ACC as compared to clinical parameters, using methods easily applicable in clinical routine. We investigated a total of 237 ACCs (96 ...

Coincidence of Primary Adrenocortical Carcinoma and Melanoma: Three Case Reports

Lynn Ko Ye , Kumar Vaishnavi , Lippert Juliane , Diaz-Cano Salvador , Skordilis Kassiani , Kimpel Otilia , Kircher Stefan , Asia Miriam , S. Elhassan Yasir , Altieri Barbara , L. Ronchi Cristina

Adrenocortical carcinoma (ACC) is a rare endocrine malignancy. ACC may rarely occur as part of familial cancer syndromes, but the majority of the cases occur sporadically. A significant proportion of sporadic ACC cases may be preceded by other malignancies and adrenal metastasis from these primary tumours may frequently occur. Herein we present three cases where sporadic ACC was identified in patients with coexistent or previous history of melanoma.Case ...

Cyclin dependent kinase 4 as promising drug target in adrenocortical carcinoma

Liang Raimunde , Weigand Isabel , Sbiera Silviu , Kircher Stefan , Lippert Juliane , Altieri Barbara , Steinhauer Sonja , Hantel Constanze , Rost Simone , Rosenwald Andreas , Kroiss Matthias , Fassnacht Martin , Ronchi Cristina

Adrenocortical carcinomas (ACC) are associated with heterogeneous prognosis and limited treatment options for advanced stages. Until now no efficient targeted therapies have been identified. This study aims to identify possible new molecular drug targets for a future personalized therapeutic approach. RNA was isolated from 40 formalin-fixed paraffin-embedded tumor samples from ACC patients (26F&14M, median age 46 yrs) with known genetic background (Lippert et al. JCEM ...

Targeted molecular analysis in adrenocortical carcinomas: a strategy towards improved personalized prognostication

Lippert Juliane , Appenzeller Silke , Liang Raimunde , Sbiera Silviu , Kircher Stefan , Altieri Barbara , Weigand Isabel , Riemens Renzo , Rosenwald Andreas , Kroiss Matthias , Rost Simone , Fassnacht Martin , Ronchi Cristina

Background: Adrenocortical carcinoma (ACC) has a heterogeneous prognosis and current medical therapies have limited efficacy in its advanced stages. Genome-wide multi-omics-studies identified molecular patterns associated with clinical outcome. Here, we aimed at identifying a molecular signature useful for both personalized prognostic stratification and druggable targets, using methods applicable in clinical routine.Methods: 117 tumor samples from 107 AC...

Mesenchymal tissue markers as potential drug targets in adrenocortical tumours

Sbiera Iuliu , Altieri Barbara , Feuchtinger Annette , Kircher Stefan , Hofner Kerstin , Walch Axel Karl , Fassnacht Martin , Ronchi Cristina L , Kroiss Matthias , Sbiera Silviu

Introduction: Adrenocortical carcinoma (ACC) is a rare, aggressive tumour with unsatisfactory treatment options in advanced disease. Activation of epithelial to mesenchymal transition (EMT) has been described as causative of metastatic spread in a variety of human cancers. Accordingly, new drugs were developed specifically targeting EMT with a focus on HGF/c-MET and FGF/FGFR signalling. We here asked whether EMT is a relevant mechanism in ACC.Methods: Ex...

Targeted molecular analysis in adrenocortical carcinomas: a way towards improved personalized prognostication

Lippert Juliane , Appenzeller Silke , Liang Raimunde , Sbiera Silviu , Kircher Stefan , Altieri Barbara , Nanda Indrajit , Weigand Isabel , Gehrig Andrea , Steinhauer Sonja , Mueller Clemens , Kroiss Matthias , Rost Simone , Rosenwald Andreas , Fassnacht Martin , Ronchi Cristina

Adrenocortical carcinoma (ACC) has heterogeneous prognosis and no effective targeted therapies. Pan-genomic studies identified complex molecular patterns related to outcome. Our study aimed at identification of an ‘easy-to-apply’ molecular signature for better personalized prognostic stratification. A total of 107 ACC patients were enrolled. Clinical/histopathological parameters of prognostic relevance were evaluated. Targeted molecular analysis was performed on DNA ...
