BACKGROUND: The promoter -1082 A/G (rs1800896) polymorphism of Interleukin-10 (IL-10) gene have been widely reported and considered to have a significant role on gastric cancer risk, but the results are inconsistent. OBJECTIVE: To clarify the association, we conducted a meta-analysis to investigate the associations IL-10 -1082 A/G polymorphism with gastric cancer. METHODS: Eligible articles were identified by searching databases including PubMed, Web of Science, and Google Scholar up to August 03, 2017. Odds ratios (OR) with corresponding 95% confidence intervals (CIs) were used to assess the association. RESULTS: A total of 30 case-control studies with 6,101 cases and 8,557 controls were included in this meta-analysis. Overall, a significant association between IL-10 -1082 A/G polymorphism and gastric cancer risk was observed under the allele model (G vs A: OR=1.305, 95% CI=1.076-1.584; P=0.007), heterozygote model and (GA vs AA: OR=1.252, 95% CI=1.252-1.054; P=0.011) and dominant model (GG+GA vs AA: OR=1.264, 95% CI=1.053-1.516; P=0.012). In the subgroup analysis by ethnicity, increased gastric cancer risk were found in Asians under the allele model (G vs A: OR=1.520, 95% CI=1.172-1.973; P=0.002), homozygote model (GG+GA vs AA: OR=1.571, 95% CI=1.023-2.414; P= 0.039), heterozygote model (GA vs AA: OR=1.465, 95% CI=1.192-1.801; P≤0.001) and dominant model (GG+GA vs AA: OR=1.448, 95% CI=1.152-1.821; P=0.002), but not among Caucasian and Latinos populations. CONCLUSION: These results suggested that the IL-10 -1082 A/G (rs1800896) polymorphism might contribute to the gastric cancer susceptibility, especially among Asians.
Background: Non-synonymous polymorphisms in XRCC1 hase been shown to reduce effectiveness of DNA repair and be associated with risk of certain cancers. In this study we aimed to clarify any association between XRCC1 Arg399Gln and colorectal cancer (CRC) risk by performing a meta-analysis of published case-control studies. Materials and Methods: PubMed and Google Scholar were searched to explore the association between XRCC1 and CRC. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to estimate the association strength.
About 50 % of patients with diffuse large cell lymphoma are candidate for salvage chemotherapy followed by bone marrow transplantation in the selected patients. In the current study we evaluated modified ICD (Irinotecan, Cisplatin, and Dexamethasone with G-CSF support) as salvage chemotherapy in the patients previously treated with R-CHOP or CHOP. In a retrospective study we evaluated 16 patients treated with modified ICD: irinotecan 65 mg/m 2 (max 100 mg)/day plus cisplatin 30 mg/m 2 (max 50 mg)/ day and dexamethasone 40 mg/day on days 1 and 8. Prednisolone 200 mg divided in 2 doses was given orally on days 2 and 9. G-CSF (PDgrastim) was administered at 300 lg/day subcutaneously on days 4-6 and 11-13. pre-and posthydration was given according to our hospital protocol. Overall response rate was 75 % for all of the patients and 90 % for the patients treated as first line salvage. The median overall survival was 23 ± 12 months. There was no grade 3/4 of neutropenia and no cycles of chemotherapy were delayed due to leucopenia. Modified ICD might be an effective salvage regimen for refractory/relapsed lymphoma patients. Unlike original ICD, leucopenia does not seem to be a limiting factor. So we conclude that modified ICD shall be considered as a safe and effective regimen for salvage chemotherapy in refractory/relapsed patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
