We treated hepatic metastasis of gastric cancer with CPT-11 therapy and obtained complete remission of the hepatic tumor that has been maintained for than 2 years postoperatively. The patient was a 71-year-old man with a history of angina pectoris. In 1988, gastric cancer was diagnosed, and he underwent distal gastrectomy at another hospital. In 2003, the patient began to suffer from regurgitation symptoms and presented to our hospital in October of the year. Remnant gastric cancer was diagnosed as a result of detailed investigation. Preoperative imaging revealed the presence of a solitary tumor (6 cm in diameter) in the posterior lobe of the liver, and it was confirmed to be a hepatic metastasis from the remnant gastric cancer by needle biopsy. We decided to treat this metastasis with postoperative systemic chemotherapy. Total resection of the remnant stomach was done in November 2003 and oral S-1 therapy was started 3 weeks after surgery. When the response of the hepatic metastasis was evaluated after the completion of 3 courses, the tumor showed enlargement. Therefore, his chemotherapy was changed to CPT-11. After a total 900 mg of CPT-11 had been administered, imaging studies confirmed disappearance of the hepatic metastasis. The patient remains disease-free and has no impairment of daily activities 2 years after resection of the remnant stomach.

Background: In malignant melanoma, liver metastases significantly reduce survival, even despite highly effective new therapies. Given the increase in metabolic liver diseases such as metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH), this study investigated the impact of liver sinusoidal endothelial cell (LSEC)-specific alterations in MASLD/MASH on hepatic melanoma metastasis.
Methods: Mice were fed a choline-deficient L-amino acid-defined (CDAA) diet for ten weeks to induce MASH-associated liver fibrosis, or a CDAA diet or a high fat diet (HFD) for shorter periods of time to induce early steatosis-associated alterations.

Background: A growing number of centers offer hepatic artery infusion pump (HAIP) chemotherapy for advanced liver malignancies. While small series have demonstrated feasibility of robotic HAIP placement, comparison of outcomes with open placement is lacking. We compared outcomes after robotic versus open HAIP placement.

Splice-switching oligonucleotides (SSOs) can restore protein functionality in pathologies and are promising tools for manipulating the RNA-splicing machinery. Delivery vectors can considerably improve SSO functionality in vivo and allow dose reduction, thereby addressing the challenges of RNA-targeted therapeutics. Here, we report a biocompatible SSO nanocarrier, based on redox-responsive disulfide cross-linked low-molecular-weight linear polyethylenimine (cLPEI), for overcoming multiple biological barriers from subcellular compartments to en-route serum stability and finally in vivo delivery challenges.

Colorectal cancer is one of the most prevalent malignant neoplasms in Brazil. Hepatectomy for resection of liver metastases plays an essential role in increasing disease-free survival, with the possibility of cure. The feasibility of liver resection depends on factors related to the remaining liver after surgery.

Cholangiocarcinoma (CCA) is a malignant biliary system tumor and the second most common primary hepatic neoplasm, following hepatocellular carcinoma. CCA still has an extremely high unfavorable prognosis, regardless of type and location, and complete surgical resection remains the only curative therapeutic option; however, due to the underhanded onset and rapid progression of CCA, most patients present with advanced stages at first diagnosis, with only 30 to 60% of CCA patients eligible for surgery. Recent innovations in medical imaging combined with the use of radiomics and artificial intelligence (AI) can lead to improvements in the early detection, characterization, and pre-treatment staging of these tumors, guiding clinicians to make personalized therapeutic strategies.
