Objectives To systematically review the efficacy and safety of docetaxel or epirubicin based regimens in the treatment of advanced gastric cancer. Methods We searched EMbase, PubMed, The Cochrane Library, Web of Science, CBM, CNKI and WanFang Data from inception to March 2017, to collect randomized controlled trials (RCTs) on docetaxel or epirubicin based regimens in the treatment of advanced gastric cancer. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was performed by using RevMan 5.3 software. Results A total of 12 RCTs involving 984 advanced gastric cancer patients were included. The results of meta-analysis showed that docetaxel based regimens were superior to epirubicin based regimens in ORR (RR=1.21, 95%CI 1.02 to 1.43, P=0.03), DCR (RR=1.13, 95%CI 1.01 to 1.26, P=0.03), 1-year survival rate (RR=1.26, 95%CI 1.01 to 1.56, P=0.04) and 2-year survival rate (RR=3.03, 95%CI 1.59 to 5.75, P=0.000 7), while there was no statistical difference between two groups in the incidence of grade Ⅲ to Ⅳ adverse events. The results of sensitivity analysis showed that docetaxel based regimens were superior to epirubicin based regimens in 2-year survival rate (RR=2.56, 95%CI 1.06 to 6.19, P=0.04), but there were no statistical differences in ORR (RR=1.13, 95%CI 0.88 to 1.45, P=0.34), DCR (RR=1.02, 95%CI 0.85 to 1.21, P=0.84) and 1-year survival rate (RR=1.29, 95%CI 0.92 to 1.80, P=0.14). The results of sensitivity analysis indicated that the overall outcomes might be affected by the risk bias of included studies. The comparision between docetaxel based regimens and epirubicin based regimens was consistent with the overall outcomes in the incidence of grade Ⅲ to Ⅳ adverse events. Conclusions Compared with epirubicin based regimens, docetaxel based regimens may have more clinical benefits for advanced gastric cancer patients. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.

Objective To evaluate the effectiveness and safety of lentinan on immune function in patients with advanced gastric cancer. Methods We searched MEDLINE (1969-2006), EMBASE (1984-2006), OVID (1969-2006), CENTRAL (Cochrane Central Register of Controlled Trials in The Cochrane Library) (Issue 4, 2006), the Chinese Biomedicine Database (1978-2006) and CNKI (1978-2006). We also handsearched relevant journals. Pharmaceutical companies were contacted to identify additional randomized controlled trials. We assessed the identified studies in order to include high quality studies. Results Ten studies (containing 786 patients) met the inclusion criteria. Six trials shown that lentinan+FAM had significant efficacy upon patients with advanced gastric cancer compared with FAM in overall response [Plt;0.01, RR1.70, 95%CI (1.39,2.09)]. In three trials, a significant effect of lentinan+FAM group compared with FAM group in quantity of CD3+ T, T4/T8, NK was found, but lower than FAM group in side- effect of digestive system [RR0.71, 95%CI (0.55,0.91)]. The other trail identified there were fewer side effects in lentinan+FAM group compared with FAM group, though did not discribe the overall response. In case the significant heterogeneity, meta-analysis could not be used for the other three trails included, since the components of chemotherapeutic agents (ATP+Co-A+Vc; DDP+ Epirubicin+5FU; 5FU+CF+VP16) were not the same. In the three trials, overall response was statistically significant better in the lentinan group than in the control group, and lentinan group could significantly increase the quantity of CD3+ T, T4/T8, NK compared with control group. Conclusions The present meta-analysis suggested that addition of lentinan to standard chemotherapy provided a significant advantage over chemotherapy alone in terms of efficacy for patients with advanced gastric cancer. However, most of trials included in the review were of low quality, therefore, it is of necessity to conduct multi-center randomized-controlled trials of high quality.
ObjectiveTo compare the clinical effects of continuous hyperthermic peritoneal perfusion chemotherapy (CHPPC) and intravenous chemotherapy for advanced gastric cancer patients, and find better nursing methods. MethodsSixty advanced gastric cancer patients who underwent chemotherapy between June 2013 and June 2014 were divided into CHPPC group (group C, n=30) and intravenous chemotherapy group (group V, n=30). We recorded the nursing methods for both the two groups, patients' satisfaction to the nursing and treatment, peritoneal metastasis rate and quality of life during the chemotherapy. ResultsThe life quality in group V was lower than that in group C (P<0.05). The differences in patients' satisfaction rate, peritoneal metastasis rate, and one-year survival rate were not significantly different between the two groups (P>0.05). ConclusionFor patients with advanced gastric cancer requiring chemotherapy, in spite of higher cost and more complicated operations, CHPPC is superior in lower adverse events rate, better quality of life during chemotherapy and doesn't decrease patients' satisfaction to the nursing and treatment.

ObjectiveTo observe the clinical curative effect of interventional chemotherapy in the treatment of advanced gastric cancer. MethodsThirty advanced gastric cancer patients underwent arterial infusion chemotherapy and embolization treatment between January and December 30, 2013. The treatment was carried out every three weeks. We evaluated the clinical results after the third treatment. The clinical improvement was assessed based on alleviation of such symptoms as epigastric pain, poor appetite, nausea, vomiting and fecal occult blood. The tumor size was evaluated through abdominal CT examination. ResultsAbdominal pain relieved in 19 out of 28 patients (67.9%); appetite improved in 18 out of 24 patients (75.0%); vomiting relieved in 15 out of 16 cases (93.8%); and fecal 9 out of 12 patients with positive occult blood turned to negative (75.0%). The total effective rate was 83.3%, and 8 patients accepted interventional therapy after operation. The survival rates during the 6, 12 and 24-month follow-up were respectively 85.0%, 65.0%, and 25.0%. ConclusionsInterventional chemotherapy and embolization treatment are effective for advanced gastric cancer, which can relieve symptoms and lower tumor stage. Some patients have a second chance of operation, which can be an effective method in the treatment of advanced gastric cancer.
