Abstract Objective Advanced adrenocortical carcinoma (ACC) is treated with mitotane alone or combined with cytotoxic chemotherapy, yet outcomes remain poor and prognostic models in this setting are lacking. This study aimed to evaluate the prognostic value of clinical parameters in a large cohort of patients with advanced ACC undergoing systemic therapy. Methods Multicenter, international cohort study investigating 418 patients with advanced ACC (61.5% = women, median age = 52 years) from 11 centers. Patients received mitotane monotherapy (n = 161), etoposide + doxorubicin + cisplatin ± mitotane (n = 178), or second-line regimens (gemcitabine + capecitabine ± mitotane or temozolomide + mitotane, n = 79). Variables included age, cortisol excess, performance status (ECOG-PS), tumor burden, and neutrophil-to-lymphocyte ratio (NLR) at start of therapy. Outcomes were overall survival (OS), time to progression (TTP), and best objective response. Results Tumor burden, cortisol excess, ECOG-PS, and NLR ≥5 independently predicted shorter OS (hazard ratio [HR] 1.55-2.68). We developed an integrated ENSAT Risk Score for Advanced ACC combining these variables: tumor burden (0-2), cortisol excess (0/1), ECOG-PS (0-2), and NLR (0/1). A score >2 (poor-risk) was significantly associated with worse OS and TTP across all treatment groups (HRs for OS: 3.05-3.96; TTP: 2.53-3.08). It also predicted poorer response to mitotane (P < .01) and second-line therapies (P = .04). Conclusions The ENSAT Risk Score for Advanced ACC is a practical, prognostic tool for patients with advanced ACC receiving systemic therapy. Based on accessible clinical and biochemical markers, it can support treatment decisions and facilitate informed discussions in routine care.

Background Corticotroph tumor progression (CTP) leading to Nelson’s syndrome (NS) is a severe and difficult-to-treat complication subsequent to bilateral adrenalectomy (BADX) for Cushing’s disease. Its characteristics are not well described, and consensus recommendations for diagnosis and treatment are missing. Methods A systematic literature search was performed focusing on clinical studies and case series (≥5 patients). Definition, cumulative incidence, treatment and long-term outcomes of CTP/NS after BADX were analyzed using descriptive statistics. The results were presented and discussed at an interdisciplinary consensus workshop attended by international pituitary experts in Munich on October 28, 2018. Results Data covered definition and cumulative incidence (34 studies, 1275 patients), surgical outcome (12 studies, 187 patients), outcome of radiation therapy (21 studies, 273 patients), and medical therapy (15 studies, 72 patients). Conclusions We endorse the definition of CTP-BADX/NS as radiological progression or new detection of a pituitary tumor on thin-section MRI. We recommend surveillance by MRI after 3 months and every 12 months for the first 3 years after BADX. Subsequently, we suggest clinical evaluation every 12 months and MRI at increasing intervals every 2–4 years (depending on ACTH and clinical parameters). We recommend pituitary surgery as first-line therapy in patients with CTP-BADX/NS. Surgery should be performed before extrasellar expansion of the tumor to obtain complete and long-term remission. Conventional radiotherapy or stereotactic radiosurgery should be utilized as second-line treatment for remnant tumor tissue showing extrasellar extension

Abstract Objective. Several smaller studies on adrenal incidentalomas (AI) suggested an association between autonomous cortisol secretion (ACS) and mortality (Di Dalmazi Lancet Diabetes Endocrinol 2014, Debono J Clin Endocrinol Metab 2014, Patrova Endocrine 2017). However, a recent meta-analysis (9 studies, 1356 patients) could not confirm these findings (Elhassan Ann Intern Med 2019). Aim. To investigate the effects of ACS on mortality, prevalence of cardiovascular (CV) risk factors, and (CV) morbidity, in a representative cohort of AI. Design. Retrospective observational study conducted at 27 ENS@T centers from 15 countries. Methods. Inclusion criteria: AI diagnosed 1996-2015, 1 mg dexamethasone suppression test, follow-up (FU) of ≥36 months, known survival status. Exclusion criteria: clinically relevant adrenal hormone excess (i.e. Cushing’s syndrome, pheochromocytoma, primary hyperaldosteronism), known malignancy. Patient stratification: serum cortisol after dexamethasone (>5 µg/dl, ACS; 1.9-5 µg/dl, possible ACS (PACS); ≤1.8 µg/dl, non-functioning adenoma (NFA)). Definition of CV events (CVE): hospitalization due to myocardial infarction and related interventions (PTCA, surgical bypass), stroke, deep vein thrombosis, pulmonary embolism. Results. 3640 patients (57% NFA, 36% PACS, 7% ACS) were considered eligible: 64% females; median age 61 years (range 18-91); median FU 84 months (36-277) (distribution between subgroups n.s.). 352 patients died during FU. Age- and sex adjusted overall survival was significantly reduced in patients with PACS (HR 1.55; 95%CI 1.24-1.94) and ACS (1.84; 1.29-2.61). Prevalence of CV risk factors were significantly higher in PACS and ACS than in NFA (hypertension: 72, 73, 57%, p<0.0001; dyslipidemia: 42, 49, 35%, p<0.0001; diabetes: 22, 25, 17%, p<0.0001) When adjusted to relevant confounders (i.e. age, sex, CV risk factors), time to first CVE was shorter in PACS (HR 1.36; 1.07-1.73) and ACS (HR 1.62; 1.10-2.40) compared to NFA. Conclusion. PACS and ACS are associated with increased overall mortality and CV morbidity. However, to prove causality a large randomized intervention trial is required.
