Results were analyzed of diagnosis and treatment of 314 patients with malignant tumours of the liver. Of these, 36 had primary tumours of the liver (PTL), 278 were presenting with metastatic tumours (MTL). In addition, an analysis was carried out in 1236 oncological patients in order that the frequency of metastasizing of tumours into the liver might be determined together with the specific weight of metastases of different locations. The rates of tumours metastasizing to the liver were found out to be 45.7, 33.3, 30.1 percent with the gallbladder, major duodenal papilla, stomach respectively. Ultrasonography is an effective diagnostic tool for malignant tumours of the liver, being of great informative value (sensitivity in PTL--97.2%, MTL--75.7%). Eight (22.2%) patients with PTL and seventeen (6.1%) ones with MTL underwent surgical treatment. The only radical modality of treatment is still anatomical resection of the liver. Investigations are under way designed to study efficiency of thermo-(cryo) destruction of solitary and single liver metastases if surgical resection is beyond the bounds of possibility.

BRAF mutations drive initiation and progression of various tumors. While BRAF inhibitors are effective in BRAF-mutant melanoma patients, intrinsic or acquired resistance to these therapies is common. Here, we identify non-receptor-type protein tyrosine phosphatase 23 (PTPN23) as an alternative effective target in BRAF-mutant cancer cells.

Background And Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common cause of hepatocellular carcinoma (HCC). In this study, we combine metabolomic and gene expression analysis to compare HCC tissues with non-tumoural tissues (NTT).
Methods: A non-targeted metabolomic strategy LC-MS was applied to 52 pairs of human MASLD-HCC and NTT separated into 2 groups according to fibrosis severity F0F1-F2 versus F3F4.
Aim: This study aims to investigate the clinical utility of the derived neutrophil-to-lymphocyte ratio (dNLR) and the Geriatric Nutritional Risk Index (GNRI) in predicting treatment outcomes for patients with unresectable hepatocellular carcinoma (HCC) undergoing combination therapy with atezolizumab and bevacizumab (Atez/Bev).
Methods: A retrospective analysis was conducted on 310 patients. The dNLR, NLR, and GNRI were calculated, and their impact on progression-free survival (PFS) and overall survival (OS) was assessed.

Introduction: Biliary tract cancer (BTC) comprises a clinically diverse and genetically heterogeneous group of tumors along the intra- and extrahepatic biliary system (intrahepatic and extrahepatic cholangiocarcinoma) and gallbladder cancer with the common feature of a poor prognosis, despite increasing molecular knowledge of associated genetic aberrations and possible targeted therapies. Therefore, the search for even more precise and individualized therapies is ongoing and preclinical tumor models are central to the development of such new approaches.
Areas Covered: The models described in the current review include simple and advanced in vitro and in vivo models, including cell lines, 2D monolayer, spheroid and organoid cultures, 3D bioprinting, patient-derived xenografts, and more recently, machine-perfusion platform-based models of resected liver specimens.

In triple-negative breast cancer (TNBC), pro-tumoral macrophages promote metastasis and suppress the immune response. To target these cells, a previously identified CD206 (mannose receptor)-binding peptide, mUNO was engineered to enhance its affinity and proteolytic stability. The new rationally designed peptide, MACTIDE, includes a trypsin inhibitor loop, from the Sunflower Trypsin Inhibitor-I.
