| 1 | Prognostic significance of vascular endothelial growth factor polymorphisms in colorectal cancer patients显示文摘AIM To investigate the associations of the genetic polymor-phisms of vascular endothelial growth factor A(VEGF-A)-1498C>T and-634G>C, with the survival of patients with colorectal cancer(CRC). METHODS A prospective cohort consisting of 131 Brazilians patients consecutively operated on with a curative intention as a result of sporadic colorectal carcinoma was studied. DNA was extracted from peripheral blood and its amplification and allelic discrimination for each genetic polymorphism was performed using the technique of polymerase chain reaction(PCR) in real-time. The real-time PCR technique was used to identify the VEGF-A-1498C>T(rs833031) and-634G>C(rs2010963) polymorphisms. Genotyping was validated for VEGF-A-1498C>T polymorphism in 129 patients and for VEGF-A-634G>C polymorphism in 118 patients. The analysis of association between categorical variables was performed using logistic regression, survival by Kaplan-Meier method and multivariate analysis by the Cox regression method. RESULTS In the univariate analysis there was a significant association(OR = 0.32; P = 0.048) between genotype CC of the VEGF-A-1498C>T polymorphism and the presence of CRC liver metastasis. There was no association between VEGF-A-1498C>T polymorphism and VEGF-A-634G>C polymorphism with further clinical or anatomopathologic variables. The genotype CC of the VEGF-A-1498C>T polymorphism was significantly correlated with the 5-year survival(P = 0.032), but not significant difference(P = 0.27) was obtained with the VEGF-A-634G>C polymorphism with the 5-year survival in the univariate analysis. The genotype CT(HR = 2.79) and CC(HR = 4.67) of the polymorphism VEGF-A-1498C>T and the genotype CC(HR = 3.76) of the polymorphism VEGF-A-634C>G acted as an independent prognostic factor for the risk of death in CRC patients. CONCLUSION The CT and CC genotypes of the VEGF-A-1498C>T and the CC genotype of the VEGF-A-634C>G polymorphisms are prognostic factors of survival in Brazilians patients with sporadic colorectal carcinoma. | Gilmar Ferreira do Espírito Santo Bianca Borsatto Galera Elisabeth Carmen Duarte Elisabeth Suchi Chen Lenuce Azis Amilcar Sabino Damazo Gabriela Tognini Saba Flávia de Sousa Gehrke Ismael Dale Cotrim Guerreiro da Silva Jaques Waisberg | 2017 | World Journal of Gastrointestinal Oncology2017，9，2： | 4 |
| 2 | Giant hepatic extra-gastrointestinal stromal tumor treated with cytoreductive surgery and adjuvant systemic therapy:A case report and review of literature显示文摘BACKGROUND Primary extra-gastrointestinal stromal tumors(E-GIST)of the liver are rare.The clinical presentation may range from asymptomatic to bleeding or manifestations of mass effect.Oncologic surgery followed by adjuvant therapy with imatinib is the standard of care.However,under specific circumstances,a cytoreductive approach may represent a therapeutic option.We describe herein the case of an 84-year-old woman who presented with a tender,protruding epigastric mass.Abdominal computed tomography scan revealed a large,heterogeneous mass located across segments III,IV,V,and VIII of the liver.The initial approach was transarterial embolization of the tumor,which elicited no appreciable response.Considering the large size and central location of the tumor and the advanced age of the patient,non-anatomic complete resection was indicated.Due to substantial intraoperative bleeding and hemodynamic instability,only a near-complete resection could be achieved.Histopathology and immunohistochemical staining confirmed the diagnosis of primary E-GIST of the liver.Considering the risk/benefit ratio for therapeutic options,debulking surgery may represent a strategy to control pain and prolong survival.CASE SUMMARY Here,we present a case report of a patient diagnosed with E-GIST primary of the liver,which was indicated a cytoreductive surgery and adjuvant therapy with imatinib.CONCLUSION E-GIST primary of the liver is a rare conditional,the treatment is with systemic therapy and total resection surgery.However,a cytoreductive surgery will be necessary when a complete resection is no possible. | Michel Ribeiro Fernandes Caroline Lorenzoni Almeida Ghezzi Tomaz J M Grezzana-Filho Flávia Heinz Feier Ian Leipnitz Aljamir Duarte Chedid Carlos Thadeu Schmidt Cerski Marcio Fernandes Chedid Cléber RositoPinto Kruel | 2021 | World Journal of Gastrointestinal Surgery2021，13，3： | 3 |
| 3 | Acute kidney injury and electrolyte disorders in COVID-19显示文摘Acute kidney injury(AKI)and electrolyte disorders are important complications of hospitalized coronavirus disease 2019(COVID-19)patients.AKI is thought to occur due to multiple pathophysiological mechanisms,such as multiple organ dysfunction(mainly cardiac and respiratory),direct viral entry in the renal tubules,and cytokine release syndrome.AKI is present in approximately one in every ten hospitalized COVID-19 patients.The incidence rates of AKI increase in patients who are admitted to the intensive care unit(ICU),with levels higher than 50%.Additionally,renal replacement therapy(RRT)is used in 7%of all AKI cases,but in nearly 20%of patients admitted to an ICU.COVID-19 patients with AKI are considered moderate-to-severe cases and are managed with multiple interdisciplinary conducts.AKI acts as a risk factor for mortality in severe acute respiratory syndrome coronavirus 2 infection,especially when RRT is needed.Electrolyte disorders are also common manifestations in hospitalized COVID-19 patients,mainly hyponatremia,hypokalemia,and hypocalcemia.Hyponatremia occurs due to a combination of syndrome of inappropriate secretion of antidiuretic hormone and gastrointestinal fluid loss from vomiting and diarrhea.When it comes to hypokalemia,its mechanism is not fully understood but may derive from hyperaldosteronism due to renin angiotensin aldosterone system overstimulation and gastrointestinal fluid loss as well.The clinical features of hypokalemia in COVID-19 are similar to those in other conditions.Hypocalcemia is the most common electrolyte disorder in COVID-19 and seems to occur because of vitamin D deficiency and parathyroid imbalance.It is also highly associated with longer hospital and ICU stay. | Gabriel Martins Nogueira Noel Lucas Oliveira Rodrigues Silva Ana Flávia Moura Marcelo Augusto Duarte Silveira JoséA Moura-Neto | 2022 | World Journal of Virology2022，11，5： | 2 |
