Subtype-specific pattern of white blood cell differential in endogenous Cushing’s syndrome

Detomas Mario , Altieri Barbara , Chifu Irina , Remde Hanna , Landwehr Laura-Sophie , Sbiera Silviu , Kroiss Matthias , Fassnacht Martin , Deutschbein Timo

Objective: Glucocorticoid excess impairs immune function, thereby predisposing patients with endogenous Cushing’s syndrome (CS) to infections. However, it is still not clear whether there is a CS-subtype specific pattern in white blood cell (WBC) and WBC differential (WBCD) count.Methods: Retrospective monocentric cohort study in patients with either overt endogenous CS or adrenal adenomas with autonomous cortisol secretion (ACS), with WBC and WBCD ...

Inflammation-Based Scores as Predictors of Treatment Response in Advanced Adrenocortical Carcinoma

Mangone Alessandra , S. Elhassan Yasir , Prete Alessandro , Asia Miriam , Detomas Mario , Altieri Barbara , Mantovani Giovanna , Ronchi Cristina L.

Background: Standard treatment for advanced adrenocortical carcinoma (ACC) is mitotane in monotherapy or combined with etoposide, doxorubicin and cisplatin (EDP), yet biomarkers predictive of treatment response are lacking. Inflammation-based scores were proposed as predictors for gemcitabine+capecitabine efficacy, used as second-line in progressive ACC. We investigated the role of inflammation-based scores in predicting response to first-line treatment in advanced ACC.<p ...

Cellular landscape of adrenocortical carcinomas determined by molecular profiling of primary, recurrent and metastatic tumour samples at single-nuclei resolution.

Altieri Barbara , S. Tourigny David , Secener Ali Kerim , Sbiera Silviu , Arampatzi Panagiota , Sauer Sascha , Fassnacht Martin , Ronchi Cristina

Background: Molecular mechanisms of malignant adrenocortical tumorigenesis remain elusive despite previous comprehensive genomic studies. Nonetheless, cellular heterogeneity of primary, recurrent and metastatic adrenocortical carcinoma (ACC) haven’t been fully investigated.Aim: To characterize the molecular profile of different cell subtypes in primary, recurrent and metastatic ACC by single-nuclei RNA sequencing (snRNA-Seq), using adult human norma...

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 ...

Can Inflammation-Based Scores Help Predict Treatment Response in Advanced Adrenocortical Carcinoma?

Mangone Alessandra , Altieri Barbara , Detomas Mario , Prete Alessandro , Abbas Haider , Felicitas Asia Miriam , Elhassan Yasir , Mantovani Giovanna , Ronchi Cristina

Background: Treatment for advanced adrenocortical carcinoma (ACC) consists of mitotane alone or combined with etoposide, doxorubicin and cisplatin (EDP), yet their efficacy is limited and burdened with significant toxicity. Moreover, markers of response are lacking. Inflammation-based scores have been proposed as prognostic factors in several malignancies including ACC, and recently also as predictors of gemcitabine+capecitabine efficacy, second-line treatment in progressive d...

Erythropoiesis in endogenous Cushing syndrome: sex-related and subtype-specific differences

Detomas Mario , Deutschbein Timo , Tamburello Mariangela , Chifu Irina , Kimpel Otilia , Sbiera Silviu , Kroisz Matthias , Fassnacht Martin , Altieri Barbara

Context: Endogenous Cushing syndrome (CS) is associated with hematological abnormalities. Nevertheless, conflicting data have been reported on erythropoiesis. Some studies reported an association between CS and anemia in men, whereas others described erythrocytosis in affected patients. Furthermore, it is unclear whether there are CS subtype-specific changes in red blood cells (RBC) parameters.Objective: To investigate sex and subtype-specific changes in...

PLK1 inhibitors as potential new treatment for adrenocortical carcinoma

Smith Gabrielle , Liang Raimunde , Chortis Vasileios , Lippert Juliane , Hantel Constanze , Altieri Barbara , Fassnacht Martin , Foster Paul , Ronchi Cristina

Background: Adrenocortical carcinoma (ACC) is a rare aggressive cancer with limited treatment options for advanced stages. By targeted RNA expression screening, we identified polo-like kinase 1 (PLK1) as one of most overexpressed genes, thus representing a potential drug target for ACC. PLK1 inhibitors are under evaluation in clinical trials for other solid cancers and seem to be more effective in TP53 mutated tumours. The aim of the study was to evaluate PLK1 protein levels i...

Neuroendocrine neoplasms (NEN) arising in uncommon sites: epidemiological and clinical features

Modica Roberta , de Cicco Federica , Bottiglieri Filomena , Di Maio Silvana , Altieri Barbara , Rainone Carmen , Faggiano Antongiulio , Colao Annamaria

Background and aim: Neuroendocrine neoplasms (NEN) show increasing incidence and varying biology, but epidemiological and clinical data for other than gastroenteropancreatic (GEP) and thoracic NEN are scattered. Furthermore the best therapeutic approach in NEN arising in uncommon sites is still debated. Aim of this study is to assess the epidemiological and clinical features of NEN arising in uncommon sites in a monocentric series of a referral center.Ma...

Epithelial to mesenchymal transition in adrenocortical tumours: focus on FGF-FGFR pathway and c-MET

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

Ad Adrenocortical carcinoma (ACC) is an aggressive tumour and treatment remains unsatisfactory in advanced disease. Activation of epithelial to mesenchymal transition (EMT) is considered causative for metastatic spread in a variety of human cancers. Accordingly, new drugs were developed specifically targeting EMT with a focus on hepatocyte growth factor (HGF)/HGF receptor (c-MET) and fibroblast growth factor (FGF)/FGF receptor (FGFR) signalling.We here a...

The Notch ligand Jagged1 is up-regulated in adrenocortical carcinomas and is associated with a favourable clinical outcome

Ronchi Cristina , Sbiera Silviu , Altieri Barbara , Steinhauer Sonja , Wild Vanessa , Bekteshi Michaela , Kroiss Matthias , Fassnacht Martin , Allolio Bruno

Background: Adrenocortical tumours consist of frequent adrenocortical adenomas (ACA) and highly malignant (ACC) with a still incompletely understood pathogenesis. Dysregulation of Notch signalling pathway is implicated in several cancers with oncogenic or tumour suppressor functions. Copy number gains and over-expression of Jagged1, a ligand of Notch receptor, was reported in ACC. The aim of the study was to evaluate the expression of Jagged1 and other Notch-r...
