Systemic inflammation is relevant in intrahepatic cholangiocarcinoma (iCCA), but controversial results exist on the prognostic role of inflammatory indexes and their correlation with tumor microenvironment. The authors aimed to explore biological values these indexes. A retrospective cohort study involving iCCA patients who underwent hepatic resection between 2010 2021 was conducted. neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte (LMR), clinic-pathological factors were recorded. Immune-cell subpopulations, isolated from surgical specimens, analyzed by flow cytometry. NLR LMR cut-offs calculated X-Tile software. Linear regression, Kaplan-Meier, Cox regression analyses total 101 considered. ≥3.83 <2.28 correlated worse survival. Patients divided into groups: 67 (66.3%) low-risk 34 (33.7%) high-risk (having at least one ratio). 5-year overall survival 49.8 18.9% for low- groups, respectively ( P =0.003).

Abstract Intrahepatic cholangiocarcinoma (iCCA) is an aggressive liver malignancy that arises from second-order biliary epithelial cells. Its incidence gradually increasing worldwide. Well-known risk factors have been described, although in many cases, they are not identifiable. Treatment options continuously expanding, but the prognosis of iCCA remains dismal. R0 resection only curative treatment, a limited number patients can benefit it. Frequently, major hepatectomies needed to completely remove tumour. This could contraindicate surgery or increase postoperative morbidity with chronic disease and small remnant volume. In cases anticipated inadequate future remnant, regenerative techniques may be used expand resectability. The role extent lymphadenectomy still matters debate. Improvements diagnosis better understanding genetic profiles might lead optimized surgical approaches drug therapies. neoadjuvant adjuvant therapies broadening, gaining more acceptance clinical practice. Combining locoregional novel drugs, such as checkpoint-inhibitors molecular-targeted molecules, improve treatment survival rates. Liver transplantation, after very poor initial results, now receiving attention for unresectable early (i.e. &lt;2 cm) cirrhotic livers, showing outcomes comparable those hepatocellular carcinoma. Ongoing prospective protocols testing efficacy transplantation unresectable, advanced tumours confined liver, sustained response treatment. changing landscape, aim our work review state-of-the-art medical iCCA.

Abstract Prostate cancer (PCa) is one of the leading causes morbidity and mortality in men. Metastasis main cause PCa‐associated death. Recent evidence indicated a significant reduction PCa associated with higher ω‐3 polyunsaturated fatty acids (PUFAs) consumption. However, underlying mechanisms remained elusive. In this study, we applied global acetylome profiling to study effect treatment. Results that oleic acid (OA, monounsaturated acid, MUFA, 100 µM) elevates while EPA (eicosapentaenoic reduces acetyl‐CoA level, which alters acetylome. After treatment, two crucial cell motility regulators, PFN1 FLNA, were found altered acetylation levels. OA increased whereas decreased level. Furthermore, promotes inhibits migration invasion. Immunofluorescence assay impedes formation lamellipodia or filopodia through reduced localization FLNA edge cells. Therefore, perturbed may be critical step acid‐affected motility. This provides some new insights into response PUFAs treatment better understanding invasion modulation.

Human cancers express altered levels of actin-binding cytoskeletal filamin A (FLNA) protein. FLNA in mammals consists an domain at its N-terminus that is followed by 24 immunoglobulin-like repeat modules interrupted two hinge regions between repeats 15–16 and 23–24. Cleavage these produces a naturally occurring C-terminal 90 kDa fragment (FLNACT) physically interacts with multiple proteins diverse functions. This cleavage leads to actin cytoskeleton remodeling, which turn contributes cellular signaling, nucleocytoplasmic shuttling transcriptional factors nuclear receptors, regulation their activities are important for initiation progression cancers. Therefore, recent studies have proposed blocking as means cancer therapy. Here, we update how has been targeted different approaches potential implications future treatment human
