Paraneoplastic acral vascular syndrome in a patient with non-small cell lung adenocarcinoma with KRAS G12A oncogenic mutation.

Paraneoplastic acral vascular syndrome (PAVS) is a rare condition characterised by signs of digital ischaemia, including Raynaud's phenomenon, acrocyanosis and digital gangrene, in the context of an underlying neoplastic process. Prompt recognition of this syndrome, as well as accurate identification and classification of the associated neoplastic condition, are crucial.This report describes the case of a woman diagnosed with PAVS secondary to stage IV non-small cell lung adenocarcinoma harbouring a Kirsten Rat Sarcoma viral homolog oncogene (KRAS) G12A mutation (p.

Metabolic Singularities in Microsatellite-Stable Colorectal Cancer: Identifying Key Players in Immunosuppression to Improve the Immunotherapy Response.

Although immune checkpoint inhibitor (ICI) therapy is currently the standard of care in microsatellite-unstable (MSI) metastatic colorectal cancer (CRC), ICI therapy, alone or in combination with other therapies, is not a treatment approach in microsatellite-stable (MSS) CRC, which is present in 95% of patients. In this review, we focus on metabolic singularities-at the transcriptomic (either bulk or single cell), proteomic, and post-translational modification levels-that induce immunosuppression in cancer and specifically in MSS CRC. First, we evaluate the current efficacy of ICIs in limited and metastatic disease in MSS CRC.

Utility of the combination of high fluorescence cells and tumor markers for the diagnosis of malignant pleural effusions.

Background: New diagnostic tools have emerged to assist the traditional diagnosis of malignant pleural effusion (MPE), such as high fluorescence cells (HFc) and tumor markers (TMs), determined by clinical laboratory automated pleural fluid workup. This study aimed to evaluate the diagnostic ability of the combination of HFc and TMs for diagnosing MPE.

Methods: We recruited hospitalized patients with pleural effusion at Parc Taulí University Hospital.
