| 1 | Assessment of vascular invasion in gastric cancer: A comparative study显示文摘AIM: To evaluate and compare detection of lymphatic and blood vessel invasion (LVI and BVI) by hematox-ylin-eosin (HE) and immunohistochemistry (IHC) in gastric cancer specimens, and to correlate with lymph node status. METHODS: IHC using D2-40 (a lymphatic endothelial marker) and CD34 (a pan-endothelial marker) was performed to study LVI and BVI in surgical specimens froma consecutive series of 95 primary gastric cancer cases. The results of the IHC study were compared with the detection by HE using McNemar test and kappa index. The morphologic features of the tumors and the presence of LVI and BVI were related to the presence of lymph node metastasis. A χ2 test was performed to obtain associations between LVI and BVI and other prognostic factors for gastric cancer. RESULTS: The detection rate of LVI was considerably higher than that of BVI. The IHC study identified eight false-positive cases and 13 false-negative cases for LVI, and 24 false-positive cases and 10 false-negative cases for BVI. The average Kappa value determined was moderate for LVI (k=0.50) and low for BVI (k=0.20). Both LVI and BVI were statistically associated with the presence of lymph node metastasis (HE: P=0.001, P=0.013, and IHC: P=0.001, P=0.019). The mor-phologic features associated with LVI were location of the tumor in the distal third of the stomach (P=0.039), Borrmann's macroscopic type (P=0.001), organ inva-sion (P=0.03) and the depth of tumor invasion (P=0.001). The presence of BVI was related only to the depth of tumor invasion (P=0.003). CONCLUSION: The immunohistochemical identification of lymphatic and blood vessels is useful for increasing the accuracy of the diagnosis of vessel invasion and for predicting lymph node metastasis. | Letícia Trivellato Gresta Ismael Alves Rodrigues-Júnior Lúcia Porto Fonseca de Castro Geovanni Dantas Cassali Mnica Maria Demas lva-res Cabral | 2013 | World Journal of Gastroenterology2013，19，24： | 8 |
| 2 | Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets. | Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo | 2021 | World Journal of Clinical Oncology2021，12，10： | 5 |
| 3 | Repurposing metformin for the treatment of gastrointestinal cancer显示文摘Diabetes mellitus type 2 and cancer share many risk factors.The pleiotropic insulin-dependent and insulin-independent effects of metformin might inhibit pathways that are frequently amplified in neoplastic tissue.Particularly,modulation of inflammation,metabolism,and cell cycle arrest are potential therapeutic cancer targets utilized by metformin to boost the anti-cancer effects of chemotherapy.Studies in vitro and in vivo models have demonstrated the potential of metformin as a chemo-and radiosensitizer,besides its chemopreventive and direct therapeutic activity in digestive system(DS)tumors.Hence,these aspects have been considered in many cancer clinical trials.Case-control and cohort studies and associated meta-analyses have evaluated DS cancer risk and metformin usage,especially in colorectal cancer,pancreatic cancer,and hepatocellular carcinoma.Most clinical studies have demonstrated the protective role of metformin in the risk for DS cancers and survival rates.On the other hand,the ability of metformin to enhance the actions of chemotherapy for gastric and biliary cancers is yet to be investigated.This article reviews the current findings on the anti-cancer mechanisms of metformin and its apparatus from pre-clinical and ongoing studies in DS malignancies. | Ademar Dantas Cunha Júnior Arinilda Campos Bragagnoli Felipe Osório Costa JoséBarreto Campello Carvalheira | 2021 | World Journal of Gastroenterology2021，27，17： | 5 |

| 5 | Evaluation of functional, autonomic and inflammatory outcomes in children with asthma显示文摘Asthma is common in childhood. This respiratory disease is characterized by persistent inflammation of the airways even when the child is not in thethroes of an attack. Chronic inflammation is caused by an imbalance between pro-inflammatory and antiinflammatory mechanisms as well as autonomic dysfunction, which plays an important role in the pathogenesis and control of this condition. The impact of these physiopathological aspects leads to inactivity and a sedentary lifestyle, which exerts an influence on functional capacity and control of the disease. The main objective of non-pharmacological therapy is the clinical control of asthma and the minimization of airway obstruction and hyperinflation during an attack. These factors can be controlled with noninvasive ventilation. The aim or the present review was to describe important neural, inflammatory and functional mechanisms that affect children with asthma. | Evelim Leal de Freitas Dantas Gomes Dirceu Costa | 2015 | World Journal of Clinical Cases2015，3，3： | 5 |
| 6 | Immunotherapy – new perspective in lung cancer显示文摘Lung carcinoma is associated with a high mortality worldwide,being the leading cause of cancer death.It is mainly classified into squamous non-small cell lung cancer(NSCLC),non-squamous NSCLC,and small cell lung cancer.However,such malignancy has been increasingly subdivided into histological and molecular subtypes to guide treatment.Therapies can be used in adjuvant and palliative settings.Regarding immunotherapy,it has been widely tested in both first or subsequent palliative lines.In this sense,drugs such as pembrolizumab,nivolumab,atezolizumab,ipilimumab,avelumab,and durvalumab have been assessed in large studies.Some of these trials have also studied these medicines in adjuvant and in maintenance therapy.In recent years,advances in immunotherapy have raised the hope that the unfavorable prognosis observed in several affected individuals can be changed.Immunotherapy has increased the overall survival in squamous NSCLC,non-squamous NSCLC,and small cell lung cancer.However,it has added to the oncology practice some side effects that are unusual in standard chemotherapy and require special clinical support.In order to show how immunotherapy is being applied in the treatment of lung carcinoma,we reviewed the main studies in adjuvant and palliative scenarios.What is the better scheme?What is the better combination?What is the better dose?When should we use immunotherapy?Does programmed cell death ligand 1 expression significantly interfere in immunotherapy efficiency?Some of these questions have already been answered,while others require more investigations. | Fillipe Dantas Pinheiro Adriano Fernandes Teixeira Breno Bittencourt de Brito Filipe Antonio Franca da Silva Maria Luísa Cordeiro Santos Fabrício Freire de Melo | 2020 | World Journal of Clinical Oncology2020，11，5： | 3 |
