The expression of legumain which has been shown overexpressed in patients with metastatic gastric cancer is positively correlated to both disease progression and outcome, and negatively correlated to microRNA (miR)-3978 expression. The RNA-binding protein, poly r(C) binding protein 1 (PCBP1) was the most downregulated protein in the metastatic tissue specimens. Quantitative real-time PCR showed that PCBP1 expression is transcriptionally downregulated in peritoneal metastasis tissues. RNA immunoprecipitation experiments showed that PCBP1 and miR-3978 are sequestered in normal peritoneal tissue, but the complex is disrupted following metastatic progression...

According to the REGARD and RAINBOW trials, ramucirumab(RAM)was introduced as second-line therapy for advanced or metastatic gastric cancer. RAM may impair wound healing due to the inhibition of angiogenesis; details on the postoperative course of patients who underwent surgery during RAM treatment remain unclear. Between 2011 and 2016, 93 patients with incurable gastric cancer were treated with RAM in our institute. Among them, 3 patients underwent surgery after RAM treatment. Case 1: A 74-year-old man with liver metastasis from gastric cancer was treated with a paclitaxel(PTX)plus RAM regimen...

Gastric cancer with peritoneal dissemination is usually considered to be oncologically unresectable and is known to have a very poor prognosis. Despite recent advances in systemic chemotherapy, peritoneal dissemination due to advanced gastric cancer (AGC) still remains the most life-threatening type of metastasis and recurrence, which usually causes ascites accumulation, intestinal obstruction, or hydronephrosis, and then seriously impairs the quality of life. In general, the median survival time of these cases is reported to be just only 6-9 months...

Tumor-associated macrophages (TAMs) expressing the multi-ligand endocytic receptor mannose receptor (CD206/MRC1) contribute to tumor immunosuppression, angiogenesis, metastasis, and relapse. Here, we describe a peptide that selectively targets MRC1-expressing TAMs (MEMs). We performed in vivo peptide phage display screens in mice bearing 4T1 metastatic breast tumors to identify peptides that target peritoneal macrophages. Deep sequencing of the peptide-encoding inserts in the selected phage pool revealed enrichment of the peptide CSPGAKVRC (codenamed "UNO")...

A 55-year-woman presented with abdominal fullness. An abdominal MRI disclosed ovarian and uterine tumors. Under the pathological diagnosis of Kruckenberg tumor, total hysterectomy and bilateral adenexectomy were performed. Gastrointestinal endoscopy disclosed type 3 on the greater curvature and anterior wall of the middle gastric body. The gastric cancer had a similar histology, which suggested the tumor origin and led to the diagnosis of c-stage IV. She received 6 courses of SOX chemotherapy. Staging laparoscopy revealed no peritoneal metastasis and negative cytodiagnosis of ascites...

BACKGROUND/OBJECTIVE: Whether gastrojejunostomy (GJJ) or duodenal stent (DS) placement is preferable for treatment of gastric outlet obstruction (GOO) in patients with unresectable pancreatic cancer is unclear. We compared the usefulness of GJJ with that of DS placement in these patients. METHODS: We retrospectively reviewed 66 consecutive patients with unresectable pancreatic cancer who underwent GJJ or DS placement for symptomatic GOO. RESULTS: We analyzed 30 patients who underwent GJJ and 23 who underwent DS placement...

Recent gastric cancer clinical trials have aimed to establish the efficacy of combination therapy over monotherapy, however, the role for genomic biomarkers in these trials has remained largely unexplored. Here, using the NanoString expression platform, we analyzed 105 gastric tumors from a randomized phase III Japanese clinical trial (GC0301/TOP002) testing the efficacy of irinotecan plus S-1(IRI-S) versus S-1 therapy. We found that previously established proliferative subtype signatures, were associated with older patients (>65 years) and liver metastasis while mesenchymal subtype signatures were associated with younger patients (≤65 years) and peritoneal metastasis...

BACKGROUND: The prognosis of gastric cancer is generally determined by tumor depth and lymph node metastasis, while the effect of cross-sectional tumor location on prognosis remains unclear. METHODS: This study recruited patients who had been diagnosed with gastric cancer and who underwent gastrectomy from 1989 to 2012. The cross-sectional locations of the gastric cancers were classified into four regions: the lesser (LC) and greater curvatures (GC), and anterior (AW) and posterior walls (PW)...

Various types of tumors, particularly those originating from the ovary and gastrointestinal tract, display a strong predilection for the peritoneal cavity as the site of metastasis. The intraperitoneal spread of a malignancy is orchestrated by a reciprocal interplay between invading cancer cells and resident normal peritoneal cells. In this review, we address the current state-of-art regarding colonization of the peritoneal cavity by ovarian, colorectal, pancreatic, and gastric tumors. Particular attention is paid to the pro-tumoral role of various kinds of peritoneal cells, including mesothelial cells, fibroblasts, adipocytes, macrophages, the vascular endothelium, and hospicells...

The metastatic spread of breast carcinoma to the stomach is rare. There are a small number of previous studies that report metastases from the breast to the stomach and these provide limited information regarding this infrequent event. Consequently, the clinicopathological features, clinical outcomes and the optimal treatment for these patients remain to be elucidated. In the present study, 78 cases of gastric metastases from breast cancer, including the current case, were identified from previous studies between 1960 and 2015...

A 69-year-old man presented to our hospital because of epigastric pain. A type 2 lesion was seen in the lesser curvature of the antrum of the stomach. A moderately differentiated adenocarcinoma(human epidermal growth factor receptor 2-negative) was diagnosed by biopsy. Abdominal computed tomography showed a mass shadow 52mm in diameter in the pyloric region invading the surrounding organs, but no evidence of distant metastasis. Chemotherapy with S-1 and cisplatin(SP therapy)was initiated because of a diagnosis of locally advanced gastric cancer...

DNA methylation of leukocyte DNA has been proposed to be a biomarker for cancer that can be used to target patients for appropriate clinical implementation. We investigated IGF2 DMR and LINE1 methylation in the leukocyte DNA and their association with clinicopathological features and prognosis of gastric cancer (GC) patients. Methylation status of IGF2 DMR and LINE1 in the leukocyte DNA was quantified using bisulfite pyrosequencing in 207 GC patients. Methylation of both IGF2 DMR and the LINE1 was significantly higher in the undifferentiated histologic type compared to the differentiated histologic type (both P = 0...

BACKGROUND: Peritoneal cytology positive for carcinoma cells (CY+) is an independent poor prognostic factor in gastric cancer, and patients with CY+ are diagnosed with stage IV disease. However, there is no standard treatment strategy for CY+ gastric cancer, whereas combination chemotherapy with fluoropyrimidine and platinum has been established as the standard treatment for unresectable advanced gastric cancer or after R2 resection. Herein, we assessed whether adding cisplatin to S-1 (SP) could improve the outcome of CY+ gastric cancer patients, as compared to S-1 monotherapy...
