Objective: To explore the surgical results and clinicopathological features of gastric cancer patients with liver metastases. Methods: The clinicopathological data and post-operative survival of 37 patients who underwent resection of liver metastasis from gastric cancer at our department from Dec. 2007 to Dec. 2014 were analyzed. Results: The 1-, 3-, and 5-year overall survival rates after resection were 91.4%, 57.9%, and 22.0%, respectively, with a median survival of 37 months. Univariate analysis revealed that lymph node metastasis, multiple hepatic metastases and no preoperative chemotherapy are unfavorable prognostic factors for overall survival...

BACKGROUND: The outcome of gastric cancer patients with peritoneal metastasis remains poor. We treated these patients with intraperitoneal and intravenous paclitaxel plus oral S-1 (tegafur/gimeracil/oteracil), followed by gastrectomy in responders. We evaluated the clinical significance of peritoneal lavage carcinoembryonic antigen (CEA) messenger RNA (mRNA) levels as a biomarker for indication of conversion gastrectomy. METHODS: The peritoneal lavage of 68 patients who received the above regimen as induction chemotherapy was repeatedly collected via intraperitoneal access ports...

Gastric cancer (GC) is one of the most common tumors worldwide. Standard treatment after early detection involves surgical excision (recurrence is possible), and metastatic gastric cancer is refractory to immuno-, radio-, and most harmful chemotherapies. Various natural compounds have shown efficacy in killing different cancers, albeit not always specifically. In this study, we show that dandelion root extract (DRE) specifically and effectively suppresses proliferation and migration in human gastric cells without inducing toxicity in noncancerous cells...

OBJECTIVE: To assess the comparative efficacy and safety of polysaccharide K (PSK), with or without chemotherapy, for patients with gastrointestinal cancer (GIC) through a systematic review and network meta-analysis. MATERIALS AND METHODS: We performed a network meta-analysis to identify evidence from randomized controlled trials. We searched PubMed, Embase and the Cochrane Library for publications up to May 2017. The prespecified primary efficacy outcomes were 1-7 year overall survival (OS), while the secondary efficacy outcomes were 1-7 year disease-free survival (DFS); we performed subgroup analyses and meta-regressions according to the cancer type (colorectal, esophagus and gastric cancer) and treatment arms (with or without chemotherapy)...

5-Fluorouracil (5-FU) is a chemotherapeutic agent used to treat a variety of gastric cancers including oesophageal squamous cell carcinoma (OSCC), for which the 5-year mortality rate exceeds 85%. Our study investigated the effects of metformin, an antidiabetic drug with established anti-cancer activity, in combination with 5-FU as a novel chemotherapy strategy, using the OSCC cell lines, WHCO1 and WHCO5. Our results indicate that metformin treatment induces significant resistance to 5-FU in WHCO1 and WHCO5 cells, by more than 5-fold and 6-fold respectively, as assessed by MTT assay...

The incidence of metastatic gastric cancer (MGC) is high and the prognosis is poor with 5-year survival rarely exceeding 5%. Systemic chemotherapy is the cornerstone for MGC in current treatment guidelines. Recent studies have revealed both reduction surgery and conversion surgery can improve patient's prognosis, indicating the value of surgical treatment in MGC. Based on the present therapeutic strategy, we discuss the indication, extent and timing of surgery for MGC. Our conclusions are as followings: the treatment of gastric cancer is chemotherapy-based, target-included and surgery-combined multidisciplinary therapy; patients with single non-curable factor are most likely to benefit from surgery-combined multidisciplinary therapy; the optimal timing for surgery depends on the response to chemotherapy; it is worthwhile to explore the conversion therapy combining target therapy and chemotherapy; the resection of metastasis lesion can be managed according to Japanese guideline; in order to establish high-level evidence, it is necessary to unite experts from different disciplines to conduct clinical trial according to the category of metastasis of gastric cancer...

PURPOSE: Positive margins after definitive resection in gastric adenocarcinoma are associated with inferior outcomes. There are few randomized data to guide optimal adjuvant therapy after positive margins. METHODS: Using the National Cancer Database, we identified 24,619 nonmetastatic gastric adenocarcinoma patients who received diagnoses from 2004 to 2013 and underwent definitive resection to analyze for predictors of positive surgical margins. Of these patients, 2754 had positive margins (11...

Gastric cancer is one of the most factors, leading to cancer-related death worldwide. However, the therapies to prevent gastric cancer are still limited and the emergence of drug resistance leads to development of new anti-cancer drugs and combinational chemotherapy regimens. Our study was aimed to explore the anti-gastric cancer effects of liquiritin (LIQ), a major constituent of Glycyrrhiza Radix, which possesses a variety of pharmacological activities. The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) preferentially inhibited tumor cells over other normal cells, when used in alone or in combination...

Abundance of the ATPase-binding cassette (ABC) transporters and deranged self-renewal pathways characterize the presence of cancer stem cells (CSCs) in gastrointestinal cancers (GI cancers), which play crucial roles in tumorigenesis, chemotherapy resistance, tumor recurrence, and cancer metastasis. Therefore, in order to ensure high cure rates, chemoquiescence, CSCs should be ablated. Recent advances in either understanding CSCs or biomarker identification enable scientists to develop techniques for ablating CSCs and clinicians to provide cancer cure, especially in GI cancers characterized by inflammation-driven carcinogenesis...

Gastrectomy with D2 lymphadenectomy plus postoperative chemotherapy is the standard treatment for resectable locally advanced gastric cancer in Japan. However, the prognosis of patients with serosa-positive tumors remains unsatisfactory because of peritoneal recurrence. This study aimed to investigate the validity of neoadjuvant therapy with docetaxel, cisplatin, and S-1 (DCS) in patients with locally advanced gastric cancer. Thirty patients with locally advanced gastric cancer underwent neoadjuvant DCS therapy at Dokkyo Medical University Hospital between June 2013 and October 2015...

Local recurrence is common after radical surgery. However, the factors that contribute to survival after local recurrence remain unclear. In this retrospective study we analyzed the relationship between time to recurrence and survival after recurrence in 74 patients with locally recurrent gastric cancer. All patients received palliative radiotherapy with or without chemotherapy. The patients were divided into two groups according to the time between gastrectomy and local recurrence: early local recurrence (ELR, < 12 months after primary surgery), and late local recurrence (LLR, ≥12 months after primary surgery)...

Serine-arginine protein kinase 1 (SRPK1) phosphorylates proteins involved in the regulation of several mRNA processing pathways including alternative splicing. SRPK1 has been reported to be over-expressed in multiple cancers including prostate, breast, lung and glioma. Several studies further identified that inhibition of SRPK1 showed tumor-suppressive effects, thus raising SRPK1 as a novel candidate chemotherapy target. Interestingly, SRPK1 plays tumor suppressing role in mouse embryonic fibroblasts, on that SRPK1-silencing induces cell transformation...

BACKGROUND: Patients with gastric cancer and peritoneal carcinomatosis have a very poor prognosis; median survival is 3 to 4 months. Palliative systemic chemotherapy is currently the only treatment available in the Netherlands. Intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) has an established role in the treatment of peritoneal carcinomatosis originating from colorectal cancer, appendiceal cancer, and pseudomyxoma peritonei; its role in gastric cancer is uncertain. Currently, there is no consensus on the choice of chemotherapeutic agents used in HIPEC for gastric cancer...
