RESUMO
PURPOSE: Muscle-invasive bladder cancer (MIBC) is an aggressive disease with a complex treatment. In Brazil, as in most developing countries, data are scarce, but mortality seems exceedingly high. We have created a centralization program involving a multidisciplinary clinic in a region comprising seven municipalities. The aim of this study is to evaluate the impact of a multidisciplinary clinic and a centralization-of-care program (CABEM program) on MIBC treatment in Brazil. PATIENTS AND METHODS: A total of 116 consecutive patients were evaluated. In group 1, 58 patients treated for MIBC before establishing a bladder cancer program from 2011 to 2017 were retrospectively evaluated. Group 2 represented 58 patients treated for MIBC after the implementation of the CABEM centralization program. Age, sex, staging, comorbidity indexes, mortality rates, type of treatment, and perioperative outcomes were compared. RESULTS: Patients from group 2 versus 1 were older (68 v 64.2 years, P = .02) with a higher body mass index (25.5 v 22.6 kg/m2, P = .017) and had more comorbidities according to both age-adjusted Charlson Comorbidity Index (4.2 v 2.8, P = .0007) and Isbarn index (60.6 v 43.9, P = .0027). Radical cystectomy (RC) was the only treatment modality for patients in group 1, whereas in group 2, there were 31 (53%) RC; three (5%) partial cystectomies; seven (12%) trimodal therapies; 13 (22%) palliative chemotherapies; and three (5%) exclusive transurethral resections of the bladder tumor. No patient in group 1 received neoadjuvant chemotherapy, whereas it was offered to 69% of patients treated with RC. Ninety-day mortality rates were 34.5% versus 5% for groups 1 versus 2 (P < .002). One-year mortality was also lower in group 2. CONCLUSION: Our data support that a centralization program, a structured bladder clinic associated with protocols, a multidisciplinary team, and inclusion of chemotherapy and radiotherapy treatments can pleasingly improve outcomes for patients with MIBC.

Biomarkers have a variety of clinical applications in multiple stages of diagnosis and therapy. Troponin T and brain natriuretic peptide are the best-known in the cardiovascular field, but experimental studies have identified new biomarkers with potential clinical value. In this article, novel biomarkers of kidney injury are investigated in the context of their relationship with atherosclerotic coronary disease. This review was carried out through a search in the PubMed database using as keywords each biomarker to be studied with the descriptor (DECS/MeSH) "Myocardial Infarction", and the keywords "coronary" and "cardiovascular", using the Boolean operator "AND". After the selection, 24 articles published between 2003 and 2017 were identified for the review. Eight biomarkers were investigated: neutrophil gelatinase-associated lipocalin (NGAL), fibroblast growth factor 23 (FGF23), tissue inhibitor of metalloproteinase-2 (TIMP-2), syndecan-1, interleukin-6 (IL-6), galectin-3, and the vascular cell adhesion molecules ICAM-1 and VCAM-1. Most identified articles were experimental studies, studies on human subjects having few participants. There are several promising biomarkers in the setting of coronary disease. The main evidence available in the literature suggests that elevated NGAL levels are associated with better prognosis after cardiac arrest and with comorbid kidney injury; elevated FGF23 is associated with coronary artery disease severity; TIMP-2 protects against coronary artery disease; increased expression of syndecan-1 is observed in myocardial infarction (MI) and protects against an exacerbated inflammatory response; IL-6 is associated with atherosclerotic disease and major cardiovascular outcomes; galectin-3 correlates with adverse clinical events post-MI; and elevated ICAM-1/VCAM-1 levels are associated with risk of coronary disease. Further studies are required to better investigate the role of each of these biomarkers in both stable coronary disease and acute coronary syndrome.
