Neutrophil-to-Lymphocyte Ratio Predicts Cancer Outcome in Locally Advanced Clear Renal Cell Carcinoma.

BACKGROUND: To evaluate the association of neutrophil-to-lymphocyte ratio (NLR) with recurrence-free survival (RFS) and overall survival (OS) in patients with locally advanced nonmetastatic clear cell renal cell carcinoma (ccRCC) undergoing radical nephrectomy. MATERIAL AND METHODS: We retrospectively identified 880 nephrectomies performed between January 2009 and December 2016 in a single center, reviewed data from 478 radical nephrectomies for kidney tumors and identified 187 patients with locally advanced nonmetastatic ccRCC (pT3-T4 N0M0). NLR was obtained preoperatively and calculated by dividing absolute neutrophil count by absolute lymphocyte count. OS and RFS were evaluated by the Kaplan-Meier method. Cox proportional-hazards regression models were used to evaluate predictors of RFS and OS. RESULTS: Among 187 patients with ccRCC (mean age 63.4 ± 11.5 years; 118 [63.1%] male), the median follow-up was 48.7 months. On univariate analysis, in patients with Fuhrman nuclear grade of differentiation 3-4, the median time to recurrence was significantly shorter with NLR ≥ 4 than < 4 (24 vs. 55 months, P = .045). On multivariable analysis adjusted for NLR ≥ 4, among all variables analyzed (NLR, microvascular invasion, sarcomatoid differentiation, tumor size and body mass index), only nuclear grade of differentiation was an independent predictor of recurrence (hazard ratio 2.18; 95% confidence interval 1.07-4.92, P = .03). The 3-year OS had no statistically significant difference between patients with NLR ≥ 4 or < 4. CONCLUSION: For patients with locally advanced, nonmetastatic ccRCC, RFS was reduced with high nuclear grade of differentiation and high preoperative NLR. These findings suggest an association between higher NLR and worse outcomes in locally advanced ccRCC.

Manifestação rara de edema agudo de pulmão associado à miocardite lúpica aguda - relato de caso / Unusual clinical manifestation of acute pulmonary edema associated to acute lupic myocarditis - case report

O lupus eritematoso sistêmico (LES) é a mais comum das doenças auto-imunes sistêmicas. Embora os rins classicamente sejam os órgãos mais acometidos no LES, o coração também pode ser afetado de forma significativa. Entretanto, a ocorrência de edema agudo de pulmão associado à miocardite lúpica é rara e de tratamento imunossupressor específico ainda incerto. O presente relato de caso revisa a literatura quanto a manifestações lúpicas do sistema cardiopulmonar, seu diagnóstico e tratamento, e descreve uma paciente lúpica jovem que evoluiu com edema agudo de pulmão decorrente de uma miopericardite lúpica aguda. O rápido diagnóstico pôde permitir o emprego da terapêutica imunossupressora adequada com reversão completa da disfunção miocárdica. Em pacientes jovens com quadro sugestivo de edema agudo de pulmão, o diagnóstico de LES deve ser considerado. O uso de pulsoterapia com corticóide endovenoso mostrou-se eficaz e seguro para o tratamento da manifestação cardíaca extrema.

Systemic lupus erythematosus is the most common systemic autoimmune disease. Although kidneys are the mainorgans affected, heart may suffer injury too. However, acute pulmonary edema associated to lupic myocarditis is rare and its specific immunosuppressive treatment is still undefined. The present case report reviews literature about lupic manifestations in heart and lungs, their diagnosis and treatment, and describes an young lupic patient that had pulmonary edema due toacute lupic myopericarditis. Prompt diagnosis enabled correct immunosuppressive therapy that resulted in a complete reversion of myocardial disfunction. Lupus is a possible diagnosis in young patients with pulmonary edema. The use of intravenous pulse therapy with corticosteroids was safe and efficient to healing of this severe myocardial manifestation.
