Comprehensive somatic profiling of gastroenteropancreatic neuroendocrine neoplasms. By Chirayu Mohindroo et al.
Figure 2. Mutational heatmap of pathogenic and likely pathogenic variants across tumors from 111 patients. Each row represents a tumor sample, and each column represents a gene. The colored tiles indicate the presence of pathogenic or likely pathogenic mutations. Gray tiles indicate unavailable data for the corresponding variable and sample, except where otherwise specified in the color legend. The heatmap illustrates the distribution and frequency of clinically relevant mutations across the cohort, alongside key clinical characteristics. Genes were grouped into broad functional categories according to their predominant biological roles described in the literature; these categories are descriptive and not mutually exclusive, as individual genes may participate in multiple biological pathways.

What does the therapeutic landscape for adrenocortical carcinoma look like beyond mitotane? A new review addresses the immunological hurdles posed by the intrinsically immune-privileged environment of the adrenal cortex, which has limited current treatment efficacy. 🔗 doi.org/10.1530/EO-26-0040
[Endocrine Oncology logo] Beyond mitotane: next-generation therapeutic landscapes in adrenocortical carcinoma. By Keya Kotecha, Katia Mariniello, Leonardo Guasti. Figure 1. Mechanistic landscape for next-generation therapeutic modalities in ACC. (A) Precision targeting via antibody-drug conjugates (ADCs) bypasses traditional immune exclusion by delivering cytotoxic payloads directly to ACC antigens, such as DLK1. After binding to the antigen on the cell surface, ADCs are internalised via endocytosis and trafficked to the endo-lysosomal compartment. Here, the acidic environment and lysosomal proteases facilitate the proteolytic cleavage or hydrolytic uncoupling of the payload from the antibody, allowing the active drug to be released into the cytosol. When the payload (such as the PBD dimer used in ADCT-701) is hydrophobic (lipophilic) and neutrally charged, it possesses the unique ability to diffuse across the plasma membrane of...Endocr Oncol EO-26-0040. doi.org/10.1530/EO-26-0040.

Metformin modifies hormone changes associated with androgen deprivation therapy for prostate cancer. By Mathew Gorman et al.

Figure 1. Mean changes in leptin (A), IL-6 (B), and IGFBP1 (C) from baseline in the metformin vs placebo groups. In PCa patients treated with ADT, commercially available ELISAs were performed on serum samples collected across six study visits from 79 patients, resulting in a total of 474 samples. The assays used are as follows for each analyte: leptin (Cat. SLP00, R&D Systems, Inc., USA), IL-6 (Cat. SS600C, R&D Systems, Inc., USA), and IGFBP1 (Cat. 11 -IGFHU -E01, ALPCO, USA). Two-tailed independent t-tests were used to determine whether significant changes in laboratory values were evident in patients receiving metformin vs placebo at 9 and 12 months. Both fasting (F) and postprandial (PP) values were assessed at these time points. The error bars represent the standard error of the mean.

By comparing the three groups of corticotroph tumors by secretory behavior (USP8+ FCTs with the highest secretion index, followed by WT FCTs with a lower secretion index and NFCTs), we found that TBX19 and PCSK1 expressions are increased in USP8+ and WT FCTs compared to NFCTs. We also found that, in FCTs, PCSK1N expression was decreased in USP8+ FCTs compared to WT FCTs.

To screen or not to screen: complexity of SDHA mutation management. By Einas Mohamed et al.

Figure 1
A structured clinical algorithm summarising the interpretation and management of SDHA variants. This flowchart integrates tumour phenotype, SDH immunohistochemistry (IHC) and germline findings to guide whether an SDHA variant should be considered ‘actionable’. In this context, an actionable SDHA variant refers to a germline or tumour finding that warrants clinical follow-up, including surveillance for SDH-related tumours and/or cascade testing for at-risk relatives. The algorithm begins with the identification of an SDHA-mutated tumour (e.g. GIST, phaeochromocytoma/paraganglioma or less typical SDH-associated tumours – such as RCC, neuroblastoma or pituitary adenoma)...Endocrine Oncology 6, 1; 10.1530/EO-25-0048
