Introduction: Adrenocortical carcinoma (ACC) is one of the most aggressive endocrine malignancies and confers a poor prognosis in advanced stages. Effective treatments are lacking. The results of immune checkpoint inhibition were disappointing with few responders only deriving clinical benefit. For the development of novel immunotherapies such as tumor vaccines and T cell-based treatments, target identification is essential. Tumor-specific mutant neoantigens that may be recogn...

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...

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 ...

Adrenocortical carcinoma (ACC) is a rare aggressive cancer with heterogeneous behaviour. Disease surveillance relies on frequent imaging, which comes with significant radiation exposure. Here we investigated the role of circulating cell-free DNA (ccfDNA) in ACC monitoring. We extracted ccfDNA from 1-4 ml EDTA-plasma using the Nonacus Cell3TMXtract or the Qiagen QIAamp MinElute kit and quantified by fluorimeter. We investigated 63 patients with ACC (25M/38F, 52±...

Adrenocortical carcinoma (ACC) is a rare tumor with heterogeneous outcome and no available targeted therapy. The aim of the study is to identify prognostic molecular markers and novel potential drug targets.A total of 43 FFPE tumor samples were retrospectively investigated for somatic mutations and copy number variations (CNV) by next-generation sequencing (160 cancer-related genes, Qiagen). Gene expression was evaluated by quantitative RT-PCR in a subgr...

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...

ContextThe occurrence of different subtypes of endogenous Cushing’s syndrome (CS) in single individuals is extremely rare. We here present the case of a female patient who was successfully cured from adrenal CS 4 years before being diagnosed with Cushing’s disease (CD).Case DescriptionA 50-year-old female was diagnosed with ACTH-independent CS and a left-sided adrenal adenoma in January 2015. After ...

Context: The occurrence of different subtypes of endogenous Cushing’s syndrome (CS) in single individuals is extremely rare. We here present the case of a female patient who was successfully cured from adrenal CS 4 years before being diagnosed with Cushing's disease (CD).Case Description: A 50-year-old female was diagnosed with ACTH-independent CS and a left-sided adrenal adenoma in January 2015. After adrenalectomy and histopathological co...

Background: Genetic alterations underlying the pathogenesis of autonomous cortisol secretion and early adrenocortical tumorigenesis have been identified in 40% of adrenocortical tumors (ACT). Nonetheless, the molecular events leading to development of ACT and steroid secretion remain obscure for a large proportion of patients.Aim: Aims of our study were to investigate the relationship between transcriptome profile and genetic background in a large series...

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 ...
