Article Synopsis
- The study aims to understand how specific molecular changes, particularly the expression of a certain gene, influence the clinical outcomes of patients with pulmonary carcinoids, which can range from slow-growing to deadly tumors.
- Researchers analyzed RNA sequencing data from two cohorts of pulmonary carcinoid patients (totaling 193) to determine the prognostic value of this gene expression and its relationship with telomerase activity, which is linked to tumor aggressiveness.
- Results showed that high expression of the gene correlates with worse survival rates and is an independent predictor of poor clinical outcomes, suggesting that it could be a key factor in assessing the severity of pulmonary carcinoids.
Background: Six thoracic pathologists reviewed 259 lung neuroendocrine tumours (LNETs) from the lungNENomics project, with 171 of them having associated survival data. This cohort presents a unique opportunity to assess the strengths and limitations of current World Health Organization (WHO) classification criteria and to evaluate the utility of emerging markers.
Patients And Methods: Patients were diagnosed based on the 2021 WHO criteria, with atypical carcinoids (ACs) defined by the presence of focal necrosis and/or 2-10 mitoses per 2 mm.
Background: Organoids are 3-dimensional experimental models that summarize the anatomical and functional structure of an organ. Although a promising experimental model for precision medicine, patient-derived tumor organoids (PDTOs) have currently been developed only for a fraction of tumor types.
Results: We have generated the first multi-omic dataset (whole-genome sequencing [WGS] and RNA-sequencing [RNA-seq]) of PDTOs from the rare and understudied pulmonary neuroendocrine tumors (n = 12; 6 grade 1, 6 grade 2) and provide data from other rare neuroendocrine neoplasms: small intestine (ileal) neuroendocrine tumors (n = 6; 2 grade 1 and 4 grade 2) and large-cell neuroendocrine carcinoma (n = 5; 1 pancreatic and 4 pulmonary).
Article Synopsis
- People with cancer often face higher risks of developing venous thromboembolism (VTE), but the link between VTE and cancer risk isn't fully understood.
- A study used genetic data to examine whether VTE could be a risk factor for various cancers and vice versa, but found no strong causal connection.
- Although there was a slight association between VTE risk and pancreatic cancer, it was influenced by blood type and didn't indicate a direct cause-and-effect relationship; overall, the findings suggest that existing links between VTE and cancer are likely due to other factors related to cancer itself.
Neuroendocrine neoplasms (NENs) comprise well-differentiated neuroendocrine tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs). Treatment options for patients with NENs are limited, in part due to lack of accurate models. We establish patient-derived tumor organoids (PDTOs) from pulmonary NETs and derive PDTOs from an understudied subtype of NEC, large cell neuroendocrine carcinoma (LCNEC), arising from multiple body sites.
