Adjuvant therapy for gastric cancer:What have we learned since INT0116?

Gastric cancer is one of the main cancer-related causes of death worldwide. The curative treatment of gastric cancer consists of tumor resection and lymphadenectomy. However, surgical treatment alone is associated with high recurrence rates. Adjuvant treatment strategies have been studied over the last decades, but there have been controversial results from the initial studies. The pivotal INT0116 study demonstrated that the use of adjuvant chemoradiotherapy with 5-fluorouracil increases relapse-free and overall survival, and it has been adopted across the Western world. The high toxicity of radiochemotherapy and suboptimal surgical treatment employed, with fewer than 10% of the patients submitted to D2 lymphadenectomy, were the main study limitations. Since its publication, other adjuvant treatment modalities have been studied, and radiochemotherapy is being refined to improve its efficacy and safety. A multimodal approach has been demonstrated to significantly increase relapsefree and overall survival, and it can be offered in the form of perioperative chemotherapy, adjuvant chemoradiotherapy or adjuvant chemotherapy, regardless of the extent of lymphadenectomy. The objective of the present review is to report the major advances obtained in the last decades in the adjuvant treatment of gastric cancer as well as the perspectives of treatment based on recent knowledge of the molecular biology of the disease.

Analysis of 12 variants in the development of gastric and colorectal cancers

AIM To evaluate the relation between 12 polymorphisms and the development of gastric cancer(GC) and colorectal cancer(CRC).METHODS In this study,we included 125 individuals with GC diagnosis,66 individuals with CRC diagnosis and 475 cancer-free individuals. All participants resided in the North region of Brazil and authorized the use of their samples. The 12 polymorphisms(in CASP8,CYP2 E1,CYP19 A1,IL1 A,IL4,MDM2,NFKB1,PAR1,TP53,TYMS,UGT1 A1 and XRCC1 genes) were genotyped in a single PCR for each individual,followed by fragment analysis. To avoid misinterpretation due to population substructure,we applied a previously developed set of 61 ancestryinformative markers that can also be genotyped by multiplex PCR. The statistical analyses were performed in Structure v.2.3.4,R environment and SPSS *** After statistical analyses with the control of confounding factors,such as genetic ancestry,three markers(rs79071878 in IL4,rs3730485 in MDM2 and rs28362491 in NFKB1) were positively associated with the development of GC. One of these markers(rs28362491) and the marker in the UGT1 A1 gene(rs8175347) were positively associated with the development of CRC. Therefore,we investigated whether the joint presence of the deleterious alleles of each marker could affect the development of cancer and we obtained positive results in all analyses. Carriers of the combination of alleles RP1 + DEL(rs79071878 and rs28361491,respectively) are at 10-times greater risk of developing GC than carriers of other combinations. Similarly,carriers of the combination of DEL + RARE(rs283628 and rs8175347) are at about 12-times greater risk of developing CRC than carriers of other *** These findings are important for the comprehension of gastric and CRC development,particularly in highly admixed populations,such as the Brazilian population.

Saturated anisotropic hydraulic conductivity of a compacted lateritic soil

引用

Journal of Rock Mechanics and Geotechnical Engineering 2018年第5期10卷 986-991页

作者： Roberto Aguiar dos santos Edmundo Rogerio Esquivel Varzea Grande Institute of Engineering Federal University of Mato Grosso Cuiaba Mato Grosso Brazil Sao Carlos School of Engineering University of Sao Paulo Sao Carlos Sao Paulo Brazil

This study focuses on the saturated anisotropic hydraulic conductivity of a compacted lateritic clayey sandy soil. The effects of the molding water content and the confining stress on the anisotropic hydraulic conductivity are investigated. The hydraulic conductivity is measured with a flexible-wall permeameter. Samples are dynamically compacted into the three compaction states of a standard Proctor compaction curve： the dry branch, optimum water content and wet branch. Depending on the molding water content and confining stress, the hydraulic conductivity may increase or decrease. In addition, the results indicate that, when the samples are compacted to the optimum water content, lower hydraulic conductivity is obtained, except at a confining stress equal to 50 kPa. The increase of the confining stress decreases the hydraulic conductivity for each of the evaluated compaction states. In the wet branch, horizontal hy- draulic conductivity is about 8 times higher than the vertical value. The anisotropic hydraulic conduc- tivities of the dry and wet branches decrease when the confining stress increases, and the opposite is observed in the optimum water content state.
