DF is related with distal tumors and patients submitted to subtotal gastrectomy. It affects not only the postoperative period with high morbidity and mortality rates, but may also have a negative impact on long-term survival.

High levels of inflammatory markers and the neutrophil-lymphocyte ratio appear to be associated with worse overall survival in solid tumors. However, few studies have analyzed the role of the neutrophil-lymphocyte ratio in gastric cancer patients scheduled to undergo curative resection. In the present study, a systematic review and meta-analysis was performed to analyze the relationship between the neutrophil-lymphocyte ratio and overall survival in patients with gastric cancer submitted to curative resection and to identify the clinicopathological features (age, gender, tumor depth, nodal involvement and tumor differentiation) that are correlated with high neutrophil-lymphocyte ratios. A literature search of PubMed, Scopus, Cochrane and EMBASE through November 2017 was conducted. Articles that included gastric cancer patients submitted to curative resection and preoperatory neutrophil-lymphocyte ratio values were included. A total of 7 studies comprising 3264 patients from 5 different countries were included. The meta-analysis revealed an association of high neutrophil-lymphocyte ratios with older age, male gender, lower 5-year overall survival, increased depth of tumor invasion, positive nodal involvement but not with histological differentiation. Evaluation of the neutrophil-lymphocyte ratio is a cost-effective method that is widely available in preoperatory settings. Furthermore, it can effectively predict prognosis, as high values of this biomarker are related to more aggressive tumor characteristics. This ratio can also be used to stratify risk in patients within the same disease stage and may be used to assist in individualized follow-up and treatment.

A high NLR was an independent risk factor for reduced survival in GC patients submitted to potentially curative resection. Calculating NLR is easily reproducible and may be incorporated in pre-operative evaluation.

Introduction Multivisceral resection (MVR) is potentially curative for selected gastric cancer patients, supposedly at the cost of increased complications. However, current data comparing MVR to standard gastrectomy (SG) is lacking. Objectives Compare complications and survival after MVR and SG. Methods In a retrospective cohort of 1015 patients with gastric adenocarcinoma, 58 underwent MVR and 466 SG. Groups were compared concerning their characteristics, complications, and survival. Results One hundred seventy‐six patients had postoperative complications. Major complications were more frequent after MVR (P = .002). Surgical mortality was 8.6% and 4.9% for MVR and SG (P = .221). Older age, higher morbidities, and MVR were independent risk factors for major complications. The odds ratio for major complications was 5.89 for MVR with one or two organs and 38.01 for MVR with three or more organs. The pancreas was the most commonly removed organ and pT4b disease were confirmed in 34 (58.6%) of the MVR cases. Disease‐free survival (DFS) was lower in MVR patients (51% vs 77.8%; P < .001), being worse according to the number of organs resected. In pN+ patients, DFS was worse after MVR. DFS was equivalent to pT4b and non‐pT4b in the MVR group. Conclusions Increased morbidity and lower survival are expected for gastric cancer patients undergoing MVR.

Background: Since the publication of the first Brazilian Consensus on Gastric Cancer (GC) in 2012 carried out by the Brazilian Gastric Cancer Association, new concepts on diagnosis, staging, treatment and follow-up have been incorporated. Aim: This new consensus is to promote an update to professionals working in the fight against GC and to provide guidelines for the management of patients with this condition. Methods: Fifty-nine experts answered 67 statements regarding the diagnosis, staging, treatment and prognosis of GC with five possible alternatives: 1) fully agree; 2) partially agree; 3) undecided; 4) disagree and 5) strongly disagree A consensus was adopted when at least 80% of the sum of the answers “fully agree” and “partially agree” was reached. This article presents only the responses of the participating experts. Comments on each statement, as well as a literature review, will be presented in future publications. Results: Of the 67 statements, there was consensus in 50 (74%). In 10 declarations, there was 100% agreement. Conclusion: The gastric cancer treatment has evolved considerably in recent years. This consensus gathers consolidated principles in the last decades, new knowledge acquired recently, as well as promising perspectives on the management of this disease.

Objective:To evaluate the impact of neutrophil-lymphocyte ratio change after curative surgery for gastric cancer.Methods:A retrospective analysis of patients with gastric cancer who underwent curative surgery between 2009 and 2017 was performed. A cutoff value was established for the neutrophil-lymphocyte ratio in the pre- and postoperative periods, according to the median value, and four subgroups were formed (low-low/low-high/high-low/high-high). Clinical-pathological and survival data were analyzed and related to these subgroups.Results:A total of 325 patients were included in the study. The cutoff values of the neutrophil-lymphocyte ratio were 2.14 and 1.8 for the pre and postoperative periods, respectively. In patients with stages I and II, the high-high subgroup presented worse overall survival (p=0.016) and disease-free survival (p=0.001). Complications were higher in the low-high subgroup of patients.Conclusion:The neutrophil-lymphocyte ratio is a low cost, efficient and reproducible marker. The prognosis individualization can be performed according to the identification of subgroups at a higher risk of complications and worse prognosis.

-Background: Benign liver tumors, due to its relative easeness its imaging identification, have their incidence increasing in population in recent years, becoming frequent in the clinical picture and often a challenge for clinicians and surgeons. Doctors began to face dilemmas related to diagnosis in asymptomatic patients with liver nodules. Aim: Update the knowledge of hepatic adenomas due to the crescent diagnosis seen in the recent years. Methods: Was performed a literature review consulting Medline/PubMed, SciELO, Embase, Lilacs database with the following descriptors: hepatic adenoma, surgery, medical treatment, diagnosis, pathophysiology and molecular biology. Conclusion: The diagnosis of incidental asymptomatic lesions is a major dilemma in clinical practice because it brings intense distress for patients and their families, and often become a challenge for the physician or surgeon. Injury is of particular interest because it can provide both benign evolution or potentially lethal complications. Recently, its resection is no more mandatory; currently, more individualized treatment are required, aiming less morbidity. In light of new advances in molecular biology, the physician who diagnoses the lesion must identify the potential unfavorable evolution, and recognize cases who need more aggressive medical management. RESUMO -Introdução:Os tumores hepáticos benignos, devido à relativa facilidade na identificação através de exames de imagem, tiveram incidência crescente na população nos últimos anos, tornando-se quadro frequente na rotina clínica e muitas vezes um desafio para clínicos e cirurgiões. Logo, o médico passou a enfrentar dilemas relacionados ao diagnóstico e conduta nestes pacientes assintomáticos e portadores de nódulos hepáticos. Objetivo: Atualizar o conhecimento dos adenomas hepáticos frente à evolução ocorrida com seu conhecimento nos últimos anos. Método: Foi efetuada revisão da literatura em consulta na Medline/Pubmed, Scielo, Embase e Lilacs com cruzamento dos seguintes descritores: adenoma hepático, cirurgia, tratamento clínico, diagnóstico, fisiopatologia e biologia molecular. Conclusão: O diagnóstico incidental de lesões assintomáticas constitui grande dilema na prática clínica, pois traz intensa angústia para o paciente e seus familiares, e muitas vezes tornam-se um desafio para o clínico ou cirurgião. É lesão de particular interesse, pois pode apresentar evolução tanto benigna como complicações potencialmente letais. O adenoma hepático deixou recentemente de ser lesão de ressecção obrigatória; atualmente, adota-se conduta mais individualizada, visando menor morbimortalidade. À luz dos novos avanços da biologia molecular, cabe ao médico que o diagnostica identificar aqueles com potencial evolução desfavorável, para que nesses seja empregada conduta mais agressiva.
