Peritoneal metastasis of gastric cancer is the main cause of death in gastric cancer patients. Peritoneal metastasis of gastric cancer is difficult to diagnose in its early stage due to lack of obvious clinical signs and symptoms, and poor treatment outcomes and prognosis are often associated with late stage peritoneal metastasis. Therefore, it is crucial to utilize effective early diagnostic tools and to improve the long-term outcomes and the prognosis of patients with advanced gastric cancer. Recently, systemic chemotherapy and intraperitoneal chemotherapy are the first line therapy, and cytoreductive operation plus abdominal cavity thermochemotherapy may be the best method in the treatment of peritoneal metastasis...

Patients with peritoneal metastasis (PM) from pancreatic cancer have a short life expectancy. Systemic combination chemotherapy leads to a median overall survival of 7-8 months. Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) is a treatment alternative, where studies in patients with PM from ovarian, gastric and colorectal cancer show a high safety profile and interesting results. This case study report data on the PIPAC treatment in patients with PM from pancreatic cancer. In a standard laparoscopy, chemotherapeutics (cisplatin and doxorubicin) are nebulized within the peritoneal cavity...

Peritoneal metastasis of gastric cancer (PMGC) is incurable and thus has an extremely poor prognosis. We have found however that locoregionally administered trastuzumab armed with a radionuclide astatine-211 ((211) At)-emitting α-particle ((211) At-trastuzumab) is effective against HER2-positive PMGC in a xenograft mouse model. We first observed that (211) At-trastuzumab can specifically bind and effectively kill NCI-N87 (N87) cells, which are HER2-positive human metastatic GC cells, both in vitro and in subcutaneous tumors...

Gastric cancer (GC) is the most common epithelial malignancy worldwide. Basic transcription factor 3 (BTF3) plays a crucial role in the regulation of various biological processes. We designed experiments to investigate the molecular mechanism underlying the role of BTF3 in GC cell proliferation and metastasis. We confirmed that BTF3 expression was decreased in GC tissues and several GC cell lines. Lentivirus-mediated downregualtion of BTF3 reduced cell proliferation, induced S and G2/M cell cycle arrest, and increased apoptosis...

CUB domain-containing protein-1 (CDCP1) is a trans-membrane protein predominantly expressed in various cancer cells and involved in tumor progression. CDCP1 is phosphorylated at tyrosine residues in the intracellular domain by Src family kinases and recruits PKCδ to the plasma membrane through tyrosine phosphorylation-dependent association with the C2 domain of PKCδ, which in turn induces a survival signal in an anchorage-independent condition. In this study, we used our cell-free screening system to identify a small compound, glycoconjugated palladium complex (Pd-Oqn), which significantly inhibited the interaction between the C2 domain of PKCδ and phosphorylated CDCP1...

Cancer-associated fibroblasts (CAFs), as the activated fibroblasts in tumor stroma, are important modifiers of tumor progression. However, the molecular mechanisms underlying the tumor-promoting properties of CAFs in gastric cancer remain unclear. Here, we show that CAFs isolated from gastric cancer produce significant amounts of interleukin-6 (IL-6). CAFs enhances the migration and EMT of gastric cancer cells through the secretion of IL-6 that activates Janus kinase 2/signal transducers and activators of transcription (JAK2/STAT3) pathway in gastric cancer cells, while deprivation of IL-6 using a neutralizing antibody or inhibition of JAK/STAT3 pathway with specific inhibitor AG490 markedly attenuates these phenotypes in gastric cancer cells induced by CAFs...

Disseminated metastasis is associated with a poor prognosis, and its management in the peritoneal or pleural cavity is crucial in the treatment of cancer. Recent studies show that ion and water transporters play important roles in fundamental cellular functions, including the regulation of cell volume that would be involved in the cancer process. Here, we review the evidence for hypotonic treatments of cancer and evaluate the potential of the cellular physiological approach in clinical management. The regulation of extracellular osmolality is a promising method, with several studies demonstrating the cytocidal effects of hypotonic solution on cancer cells...
