Abstract Colorectal Cancer (CRC) is the third most common type of cancer worldwide and ranks second in mortality. Screening programs for early detection and treatment have been implemented in several countries. Economic evaluations are an important tool to support decision-making about reimbursement and coverage decisions in health systems and, therefore, to support efficient resource allocation. The article aims to review the up-to-date evidence on economic evaluations of CRC screening strategies. MEDLINE, EMBASE, Web of Science, SCOPUS, SciELO, Lilacs, CRD databases, and lists of references were reviewed to identify relevant literature regarding full economic evaluations of CRC screening in asymptomatic average-risk individuals over 40 years old. Searches were conducted with no restriction to language, setting, or date. Qualitative syntheses described CRC screening strategies and comparators (baseline context), study designs, key parameter inputs and incremental cost-effectiveness ratios. Seventy-nine articles were included. Most of the studies were from high-income countries and a third-party payer perspective. Markov models were predominantly used, although microsimulation has been increasingly adopted in the last 15 years. The authors found 88 different screening strategies for CRC, which differed in the type of technique, the interval of screening, and the strategy, i.e., isolated or combined. The annual fecal immunochemical test was the most predominant screening strategy. All studies reported cost-effective results in their scenarios compared to no screening scenarios. One-quarter of the publications reported cost-saving results. It is still necessary to develop future economic evaluations in Low- and Middle-Income Countries (LMICs), which account for the high burden of disease.

OBJECTIVES: Strategic planning for coronavirus disease (COVID-19) care has dominated the agenda of medical services, which have been further restricted by the need for minimizing viral transmission. Risk is particularly relevant in relation to endoscopy procedures. This study aimed to describe a contingency plan for a tertiary academic cancer center, define a strategy to prioritize and postpone examinations, and evaluate the infection rate among healthcare workers (HCWs) in the endoscopy unit of the Cancer Institute of the State of São Paulo (ICESP). METHODS: We created a strategy to balance the risk of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and to mitigate the effects of postponing endoscopic procedures in oncological patients. A retrospective analysis of prospectively collected data on all endoscopies between March and June 2020 compared with those during the same period in 2019 was carried out. All HCWs were interviewed to obtain clinical data and SARS-CoV-2 test results. RESULTS: During the COVID-19 outbreak, there was a reduction of 55% in endoscopy cases in total. Colonoscopy was the most affected modality. The total infection rate among all HCWs was 38%. None of the senior digestive endoscopists had COVID-19. However, all bronchoscopists had been infected. One of three fellows had a serological diagnosis of COVID-19. Two-thirds of all nurses were infected, whereas half of all technicians were infected. CONCLUSIONS: In this pandemic scenario, all endoscopy services must prioritize the procedures that will be performed. It was possible to maintain some endoscopic procedures, including those meant to provide nutritional access, tissue diagnosis, and endoscopic resection. Personal protective equipment (PPE) seems effective in preventing transmission of COVID-19 from patients to digestive endoscopists. These measures can be useful in planning, even for pandemics in the future.

OBJECTIVES: Since the outbreak of the novel coronavirus disease 2019 (COVID-19), all health services worldwide underwent profound changes, leading to the suspension of many elective surgeries. This study aimed to evaluate the safety of elective colorectal surgery during the pandemic. METHODS: This was a retrospective, cross-sectional, single-center study. Patients who underwent elective colorectal surgery during the COVID-19 pandemic between March 10 and September 9, 2020, were included. Patient data on sex, age, diagnosis, types of procedures, hospital stay, mortality, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) preoperative screening tests were recorded. RESULTS: A total of 103 colorectal surgical procedures were planned, and 99 were performed. Four surgeries were postponed due to positive preoperative screening for SARS-CoV-2. Surgical procedures were performed for colorectal cancer (n=90) and inflammatory bowel disease (n=9). Laparoscopy was the approach of choice for 43 patients (43.4%), 53 (53.5%) procedures were open, and 3 (3%) procedures were robotic. Five patients developed COVID-19 in the postoperative period, and three of them died in the intensive care unit (n=3/5, 60% mortality). Two other patients died due to surgical complications unrelated to COVID-19 (n=2/94, 2.1% mortality) (p<0.01). Hospital stay was longer in patients with SARS-CoV-2 infection than in those without (38.4 versushttps://doi.org/10.3 days, respectively, p<0.01). Of the 99 patients who received surgical care during the pandemic, 94 were safely discharged (95%). CONCLUSION: Our study demonstrated that elective colorectal surgical procedures may be safely performed during the pandemic; however, preoperative testing should be performed to reduce in-hospital infection rates, since the mortality rate due to SARS-CoV-2 in this setting is particularly high.

RESUMO Introdução: embora seja uma doença rara, a imunodeficiência comum variável (IDCV) destaca-se como a imunodeficiência primária sintomática mais frequente. Os portadores são propensos a uma série de infecções bacterianas recorrentes, além do risco de desenvolver doenças autoimunes e neoplasias incluindo o câncer gástrico (CG). Apesar do risco reconhecido, não existem protocolos específicos padronizados para o manejo do CG nesses pacientes, de modo que os resultados oncológicos relatados são variados. Assim, esse estudo tem como objetivo descrever as características clinicopatológicas e prognóstico de pacientes com IDCV submetidos ao tratamento cirúrgico do CG. Métodos: foram avaliados retrospectivamente todos os pacientes com CG submetidos a tratamento cirúrgico entre 2009 e 2020. Posteriormente foram identificados pacientes com diagnóstico de IDCV e esse grupo foi comparado com o restante dos pacientes sem nenhuma imunodeficiência. Resultados: dentre os 1101 pacientes com CG avaliados no período, 10 apresentavam algum tipo de imunodeficiência e 5 foram diagnosticados com IDCV. Os pacientes com IDCV apresentaram idade menos avançada, menor IMC e lesões com menor diâmetro em comparação aqueles sem IDCV. Quatro pacientes foram submetidos à gastrectomia curativa e um paciente realizou jejunostomia. Dois pacientes foram a óbito (1 paliativo e 1 curativo) e um paciente apresentou recidiva da doença. Não houve diferença estatisticamente significativa em relação à incidência de complicações pós-operatórias e sobrevida entre os grupos avaliados. Conclusão: a incidência IDCV nos pacientes com CG submetidos à tratamento cirúrgico foi de 0,5% ocorrendo em idade menos avançada mas sem diferença com relação aos resultados cirúrgicos e oncológicos.

ABSTRACT Introduction: although it is a rare disease, common variable immunodeficiency (CVID) stands out as the most frequent primary symptomatic immunodeficiency. Carriers are prone to a variety of recurrent bacterial infections, in addition to the risk of developing autoimmune diseases and neoplasms including gastric cancer (GC). Despite the recognized risk, there are no specific standardized protocols for the management of GC in these patients, so the reported oncological results are varied. Thus, this study aims to describe the clinicopathological characteristics and prognosis of patients with CVID undergoing surgical treatment of GC. Methods: all patients with GC undergoing surgical treatment between 2009 and 2020 were retrospectively evaluated. Later, patients diagnosed with CVID were identified and this group was compared with the remaining patients without any immunodeficiency. Results: among the 1101 patients with GC evaluated in the period, 10 had some type of immunodeficiency, and 5 were diagnosed with CVID. Patients with CVID had younger age, lower BMI, and smaller lesions compared to those without CVID. Four patients underwent curative gastrectomy and one patient underwent jejunostomy. Two patients died (1 palliative and 1 curative) and one patient had disease recurrence. There was no statistically significant difference regarding the incidence of postoperative complications and survival between the evaluated groups. Conclusion: the CVID incidence in patients with GC undergoing surgical treatment was 0.5%, occurring at a less advanced age, but with no difference regarding surgical and oncological results.

OBJECTIVE: The folate pathway is involved in hepatic carcinogenesis and angiogenesis. Polymorphisms in genes related to such processes, including methylene tetrahydrofolate reductase (MTHFR) and vascular endothelial growth factor (VEGF)] may play an important role in the development of hepatocellular carcinoma (HCC). The objective of this study was to evaluate MTHFR and VEGF polymorphisms in Brazilian patients with hepatitis C virus (HCV)-related HCC. METHODS: A total of 119 patients diagnosed with confirmed HCC and HCV were included in the study. SNP genotyping assays were performed using real-time PCR. VEGFA (rs2010963, rs3025039, and rs833061) and MTHFRC677T (rs1801133, rs1801131) polymorphisms were evaluated. RESULTS: The C alleles of MTHFR (rs1801131) and VEGF (rs2010963) were associated with protection against the development of multinodular HCC, while the T allele of MTHFR (rs1801133) was associated with a higher risk of multinodular presentation [p=0.04 OR 1.835 CI (1.022-3.297)]. Multivariate analysis revealed that the GG/GC genotypes of VEGF rs2010963 were independently associated with multinodular tumors at diagnosis (p=0.013; OR 4.78 CI (1.38-16.67)]. CONCLUSION: Our results suggest that these polymorphisms may increase the risk of rapid tumor progression in patients with HCV infection. This subgroup of patients with HCC and who present polymorphism is more likely to be diagnosed with multinodular disease and not be amenable to receiving curative treatments. These data must be validated in larger cohorts, and the screening intervals can be customized based on genetic history.

RESUMO Objetivo: Avaliar o impacto da alteração da relação neutrófilo-linfócito após ressecção curativa por câncer gástrico. Métodos: Realizou-se análise retrospectiva de pacientes com câncer gástrico submetidos à gastrectomia curativa entre 2009 e 2017. Foi estabelecido valor de corte para a relação neutrófilo-linfócito nos períodos pré e pós-operatório de acordo com a mediana, e quatro subgrupos foram formados (baixo-baixo/baixo-alto/alto-baixo/alto-alto). Dados clínicos e patológicos e de sobrevida foram analisados e relacionados com estes subgrupos. Resultados: Foram incluídos no estudo 325 pacientes. Os valores de corte para a relação neutrófilo-linfócito foram 2,14 e 1,8 para os períodos pré e pós-operatório, respectivamente. Em pacientes com estádios I e II, o subgrupo alto-alto apresentou pior sobrevida global (p=0,016) e sobrevida livre de doença (p=0,001). As complicações ocorreram mais em pacientes do subgrupo baixo-alto. Conclusão: A relação neutrófilo-linfócito é um marcador de baixo custo, eficiente e reprodutível. A individualização do prognóstico pode ser realizada de acordo com a identificação de subgrupos com maior risco de complicações e pior prognóstico.

ABSTRACT 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.

RESUMO Racional : A terapia de conversão no câncer gástrico (CG) é definida como o uso de quimio/radioterapia seguida de ressecção cirúrgica com intenção curativa de um tumor que era considerado irressecável ou oncologicamente incurável. Objetivo : Avaliar os resultados da terapia de conversão no tratamento do CG. Métodos : Análise retrospectiva de todas as operações de CG entre 2009 e 2018. Os pacientes que receberam alguma terapia antes da operação foram também identificados para definir o grupo de conversão. Resultados : Entre 1003 operações realizadas para o CG, 113 foram submetidos ao tratamento neoadjuvante e 16 (1,6%) considerados como terapia de conversão. As principais indicações para o tratamento foram: lesões T4b (n=10), metástase linfonodal (n=4), carcinomatose peritoneal e metástase hepática em 1 caso cada. O diagnóstico foi feito por exame de imagem em 14 casos (75%) e durante o procedimento cirúrgico em 4 casos (25%). Os esquemas quimioterápicos mais utilizados foram XP e mFLOX. Complicações cirúrgicas maiores ocorreram em 4 casos (25%) e 1 (6,3%) foi a óbito. Após seguimento médio de 20 meses, 11 pacientes (68,7%) apresentaram recidiva e 9 (56,3%) morreram. Sobrevida livre de recidiva prolongada acima de 40 meses ocorreu em dois casos. Conclusão : A terapia de conversão pode oferecer possibilidade de sobrevida prolongada para um grupo de pacientes com CG considerados inicialmente fora das possibilidades terapêuticas.

ABSTRACT Background: Conversion therapy in gastric cancer (GC) is defined as the use of chemotherapy/radiotherapy followed by surgical resection with curative intent of a tumor that was prior considered unresectable or oncologically incurable. Aim: To evaluate the results of conversion therapy in the treatment of GC. Methods: Retrospective analysis of all GC surgeries between 2009 and 2018. Patients who received any therapy before surgery were further identified to define the conversion group. Results: Out of 1003 surgeries performed for GC, 113 cases underwent neoadjuvant treatment and 16 (1.6%) were considered as conversion therapy. The main indication for treatment was: T4b lesions (n=10), lymph node metastasis (n=4), peritoneal carcinomatosis and hepatic metastasis in one case each. The diagnosis was made by imaging in 14 cases (75%) and during surgical procedure in four (25%). The most commonly used chemotherapy regimens were XP and mFLOX. Major surgical complications occurred in four cases (25%) and one (6.3%) died. After an average follow-up of 20 months, 11 patients (68.7%) had recurrence and nine (56.3%) died. Prolonged recurrence-free survival over 40 months occurred in two cases. Conclusion: Conversion therapy may offer the possibility of prolonged survival for a group of GC patients initially considered beyond therapeutic possibility.

RESUMO Racional: Tradicionalmente a omentectomia total é realizada juntamente com a ressecção gástrica associada à linfadenectomia na cirurgia do câncer gástrico. No entanto, evidências sólidas em relação ao seu benefício oncológico são escassas . Objetivo: Avaliar a incidência de metástases em linfonodos do omento maior em pacientes submetidos à gastrectomia potencialmente curativa por câncer gástrico, assim como, avaliar os fatores de risco para a ocorrência e a evolução dos pacientes. Métodos: Pacientes consecutivos submetidos à gastrectomia D2/D2 modificada devido ao adenocarcinoma gástrico foram analisados retrospectivamente a partir de um banco de dados. Resultados: Dos 284 pacientes, cinco (1,8%) tinham linfonodos metastáticos no omento maior (um pT3N3bM0; dois pT4aN3bM0; um pT4aN2M0 e um pT4bN3bM0). Quatro faleceram e um estava em tratamento paliativo com quimioterapia devido à recidiva da doença. Os linfonodos metastáticos no omento maior tiveram correlação significativa com o tamanho do tumor (p=0,018), estádio N (p<0,001), estádio clínico (p=0,022), invasão venosa (p=0,003), recorrência (p=0,006), local de recorrência (peritônio p=0,008; fígado p=0,023; ovário p=0,035) e óbito (p=0,008). Conclusão: A incidência de linfonodos metastático no omento maior de pacientes submetidos à gastrectomia radical por câncer gástrico é baixa. A omentectomia total pode ser evitada em tumores menores que 5,25 cm e estádios T1/T2. Entretanto, a presença de metástases linfonodais no omento maior está associada à recidiva no peritônio, fígado, ovário e óbito.

ABSTRACT Background: Traditionally, total omentectomy is performed along with gastric resection and extended lymphadenectomy in gastric cancer (GC) surgery. However, solid evidences regarding its oncologic benefit is still scarce. Aim: To evaluate the incidence of metastatic omental lymph nodes (LN) in patients undergoing curative gastrectomy for GC, as well as its risk factors and patients’ outcomes. Methods: All consecutive patients submitted to D2/modified D2 gastrectomy due to gastric adenocarcinoma from March 2009 to April 2016 were retrospectively reviewed from a prospective collected database. Results: Of 284 patients included, five (1.8%) patients had metastatic omental LN (one: pT3N3bM0; two: pT4aN3bM0; one: pT4aN2M0 and one pT4bN3bM0). Four of them deceased and one was under palliative chemotherapy due relapse. LN metastases in the greater omentum significantly correlated with tumor’s size (p=0.018), N stage (p<0.001), clinical stage (p=0.022), venous invasion growth (p=0.003), recurrence (p=0.006), site of recurrence (peritoneum: p=0.008; liver: p=0.023; ovary: p=0.035) and death (p=0.008). Conclusion: The incidence of metastatic omental LN of patients undergoing radical gastrectomy due to GC is extremely low. Total omentectomy may be avoided in tumors smaller than 5.25 cm and T1/T2 tumors. However, the presence of lymph node metastases in the greater omentum is associated with recurrence in the peritoneum, liver, ovary and death.

RESUMO CONTEXTO: O tratamento do câncer de reto médio e distal evoluiu muito nas últimas décadas devido à disseminação da técnica de excisão total do mesorretal e ao uso de quimioterapia e radioterapia neoadjuvantes. No entanto, essa abordagem multidisciplinar pode afetar a qualidade de vida dos pacientes de várias maneiras que merecem ser adequadamente avaliadas. OBJETIVO: Avaliar a qualidade de vida imediata e tardia relacionada à saúde em pacientes tratados de câncer retal com intenção curativa. MÉTODOS: Estudo prospectivo que incluiu pacientes com câncer primário de reto médio ou baixo não metastático. Foram aplicados os questionários EORTC QLQ-C30 e EORTC-CR38 antes, 3 meses e 12 meses após o tratamento. As médias dos escores dos questionários foram estratificadas em quatro categorias para fins de comparação dos resultados nos diferentes momentos. RESULTADOS: Vinte e nove pacientes responderam aos 1º e 2º questionários e 12 responderam os três questionários. A idade média foi de 50,8 anos e 62% do sexo feminino. Preservação esfincteriana foi possível em 89,6%. As médias de escores globais de saúde e qualidade de vida melhoraram tanto após 3 meses quanto após 12 meses. Função cognitiva, dor, insônia, constipação, sintomas gastrointestinais, problemas esfincterianos, perda de peso melhoraram tanto no período imediato quanto tardio. Problemas sexuais masculinos e femininos e perspectiva futura pioraram tanto no período precoce quanto tardio. As demais funções ou sintomas ou itens não se alteraram. CONCLUSÃO: Apesar da complexidade do tratamento do câncer de reto dentro de um serviço especializado, a qualidade de vida ficou preservada ou melhor na maioria das características estudadas.

ABSTRACT BACKGROUND: The treatment of median and distal rectal cancer has evolved a lot in the last decades due to the dissemination of the technique of total mesortal excision and the use of neoadjuvant chemotherapy and radiotherapy. However, this multidisciplinary approach can affect patients’ quality of life in a number of ways that deserve to be adequately assessed. OBJECTIVE: To evaluate immediate and late health related quality of life in patients with rectal cancer treated with curative intent. METHODS: Prospective study including patients with non-metastatic mid or low rectal cancer. EORTC QLQ-C30 and EORTC-CR38 questionnaires were applied before, 3 months and 12 months after treatment. The mean scores of the questionnaires were stratified into 4 categories for the purpose of comparing the results at different moments. RESULTS: Twenty nine patients completed the 1st and 2nd questionnaires and 12 completed the three questionaries. Patient´s mean age was 50.8 years and 62% were female. Sphincter preservation was possible in 89.6%. Overall health scores and quality of life improved after three months after 12 months. After three months, sexual satisfaction, female sexual problems and future perspective were worsen, but gastrointestinal symptoms, sphincter problems, and weight loss were improved. After 12 months the Future Perspective deteriorated, but there was improvement of the problems related to stoma, sphincter problems and body image. CONCLUSION: Despite the complexity of the treatment of rectal cancer within a specialized service, quality of life was preserved and was satisfactory in most of the studied aspects.

OBJECTIVE: Our aim was to evaluate the Japan Gastroenterological Endoscopy Society criteria for endoscopic submucosal resection of early gastric cancer (EGC) based on the experience in a Brazilian cancer center. METHODS: We included all patients who underwent endoscopic submucosal resection for gastric lesions between February 2009 and October 2016. Demographic data and information regarding the endoscopic resection, pathological report and follow-up were obtained. Statistical calculations were performed with Fisher’s exact test and chi-square tests, with 95% confidence intervals. RESULTS: In total, 76% of the 51 lesions were adenocarcinomas, 16% were adenomas, and 8% had other diagnoses. The average size was 19.9 mm (±11.7). The average procedure length was 113.9 minutes (±71.4). The complication rate was 21.3%, with only one patient who needed surgical treatment (transmural perforation). Among the adenocarcinomas, 39.5% met the classic criteria for curability, 31.6% met the expanded criteria and 28.9% met the criteria for noncurative resection. Analysis of the indication criteria and curability revealed differences among cases with “only-by-size” expanded criteria (64.28%), other expanded criteria (40%) and classic criteria (89.47%), with a p-value of 0.049. During follow-up (15.8 months; ±14.3), 86.1% of the EGC patients had no recurrence. When well-differentiated and poorly differentiated lesions or lesions included in the classic and expanded criteria were compared, there were no differences in recurrence. The noncurative group presented a higher recurrence rate than the classic group (p=0.014). CONCLUSION: These results suggest that the Japanese endoscopic submucosal resection criteria might be useful for endoscopic treatment of EGC in Western countries.
