ObjectiveTo summarize controversy and progress of multi-slice spiral CT in efficacy evaluation of transformation therapy for advanced gastric cancer.MethodThe recent studies published at home and abroad on the spiral CT in evaluating the therapeutic effect of transformation therapy for the advanced gastric cancer were reviewed and analyzed.ResultsIn recent years, though the energy spectrum and dual-energy CT examinations had appeared, the most common tool in evaluating of the efficacy of transformation therapy for the advanced gastric cancer was the spiral CT. The most common evaluation standard was still the RECIST standard.ConclusionsSpiral CT has its outstanding diagnostic significance in therapeutic evaluation of transformation therapy for advanced gastric cancer. Although there is some controversy, with advancements of a large number of studies, it will greatly help diagnosis and treatment of advanced gastric cancer.
Objective To systematically evaluate the safety and efficacy of trastuzumab combined with chemotherapy for HER-2 positive patients with advanced gastric cancer. Methods We searched ClinicalTrails.gov, PubMed, EMbase, Web of Science, The Cochrane Library (Issue 5, 2016), CNKI, CBM, WanFang Data, VIP and major meeting proceeding databases (ASCO and ESMO) from inception to May 2016, to collect randomized controlled trials (RCTs) or non-RCTs about trastuzumab combined with chemotherapy versus chemotherapy alone for advanced gastric cancer. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was performed by using RevMan 5.3 software. Results Nine studies involving 1 034 HER-2 positive patients were included, of which three were RCTs and the other six were non-RCTs. Meta-analysis results indicated that the trastuzumab combined with chemotherapy group (the trial group) was superior to the chemotherapy alone group (the control group) in complete remission (OR=2.76, 95%CI 1.40 to 5.44,P=0.003), partial remission (OR=1.81, 95%CI 1.40 to 2.33,P<0.000 01), overall response rate (OR=2.09, 95%CI 1.63 to 2.68,P<0.000 01) and disease control rate (OR=2.20, 95%CI 1.63 to 2.98,P<0.000 1), while there was no statistical significances in stable disease (OR=0.87, 95%CI 0.66 to 1.14,P=0.31). In terms of safety, the incidence of diarrhea (OR=1.51, 95%CI 1.10 to 2.06,P=0.01) and erythra (OR=4.35, 95%CI 1.25 to 15.10,P=0.02) in the trial group were higher than the control group. However, other adverse reactions were no significant differences in two groups. Conclusion Compared with chemotherapy alone, trastuzumab combined with chemotherapy in the treatment of HER-2 positive patients with advanced gastric cancer can significantly improve response rate, but it may increase the incidence of diarrhea and erythra. Because of the limited quality and quantity of the included studies, the above conclusion needs to be verified by conducting more high quality studies.

ObjectiveTo understand the latest research progress in the treatment of advanced gastric cancer (AGC) and explore the optimal treatment strategy. Method The latest literature on the treatment of AGC was retrieved and reviewed. Results For patients with AGC, chemotherapy, radiotherapy, targeted therapy, immunotherapy, palliative therapy, nutritional support, and traditional Chinese medicine therapy were currently adopted in clinic, the combination of them were used usually. Some patients obtained good therapeutic effects by new chemotherapy drugs and antibody conjugated drugs. In the era of first-line immunotherapy or targeted therapy, first-line immunotherapy alone, immunotherapy in combination with chemotherapy, double immunotherapy, and immunotherapy combined with anti-angiogenesis targeted drugs for AGC had represented some survival benefits. ConclusionsThe research, development, and widespread application of new anti-tumor drugs have continuously expanded the treatment methods for AGC. The development of tumor molecular biology provides an opportunity for the treatment of AGC, and the precise diagnosis and treatment pattern guided by molecular typing is gradually maturing. However, the treatment of AGC is still facing challenges. In the era of precision medicine, facing the higher heterogeneity of gastric cancer, the dilemma of precise treatment of drugs for AGC, and the research and development of new anti-tumor drugs, the optimal treatment mode of AGC still needs more clinical exploration. It is necessary to comprehensively consider various aspects such as the patient’s physical condition, previous treatment status, and drug accessibility.
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.
ObjectiveTo evaluate the relationship between methylenetetrahydrofolate reductase (MTHFR) gene C677T polymorphism and efficacy of fluorouracil-based chemotherapy in patients with advanced gastric cancer (AGC). MethodsComputer retrieval in China Journal Full-text Database, Chinese Science and Technology Periodical Database, Wanfang database, Chinese Biomedical Literature Database, PubMed, EMbase, Cochrane Library and Web of Science Database (from their establishment to May 28, 2013) was performed to include case-control studies on MTHFR gene C677T polymorphism and sensitivity to fluorouracil-based chemotherapy in patients with advanced gastric cancer. Statistical analysis was done by using RevMan 5.1 software. ResultsSeven case-control studies with 775 patients were included. The meta-analysis showed that among MTHFR C677T genotypes, for TT vs. CC, OR=4.63, 95%CI (1.23, 17.4); and for CC+CT vs. TT, OR=0.21, 95%CI (0.06, 0.78). Subgroup analysis of Asian group showed that for TT vs. CC, OR=32.99, 95%CI (11.40,95.42); and for CC+CT vs. TT, OR=0.04, 95%CI (0.02, 0.10). Sensitivity analysis performed according to different detection methods showed that for TT vs. CC, OR=6.03, 95%CI (1.53, 23.72); and for CC+CT vs.TT, OR=0.17, 95%CI (0.04, 0.68). ConclusionPolymorphism of MTHFR C677T gene may be associated with sensitivity to fluorouracil-based chemotherapy in patients with AGC.
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.
