RESUMO

PURPOSE: To develop a risk score based on a prognostic model and a nomogram integrating baseline clinicopathological variables to predict bladder cancer-specific survival (BCSS) to neoadjuvant chemotherapy (NAC) in muscle-invasive bladder cancer (MIBC) patients. METHODS: We retrospectively identified a consecutive sample of 247 MIBC patients treated with cisplatin-based NAC-plus-cystectomy in two Spanish hospitals between 2000 and 2019. Age at MIBC diagnosis, sex, histology, lymphovascular invasion, previous non-MIBC, hydronephrosis, and clinical TNM were included in the initial Cox regression model. A risk score was computed based on the final prognostic model and a nomogram was used to estimate BCSS at 2 and 5 years. RESULTS: Median age was 66 years; 89% were males; 83% had pure urothelial carcinoma; 16.2% had previous non-MIBC. Clinical stage was T2N0, T3-4aN0, and Tx-4N + in 24%, 57%, and 19% of patients, respectively. Complete pathological response was seen in 29.4% and downstaging to non-MIBC (ypT1, ypTa, ypTis) in 12.5% of patients. Overall 5-year BCSS was 59%. Four prognostic factors were identified: variant histology, previous non-MIBC, female sex and hydronephrosis. By adding the points attributed to each of these factors, we categorized patients in three groups: low-risk (0 points); intermediate-risk (1-9 points); high-risk (≥ 10 points). Five-year BCSS was 72%, 53%, and 15%, respectively (p < 0.0001). CONCLUSION: We developed a nomogram and risk score based on four baseline clinicopathological characteristics to predict BCSS to NAC-plus-cystectomy in MIBC patients. If validated in prospective studies, this nomogram can be useful for selecting patients likely to benefit from NAC.

RESUMO

OBJECTIVE: Nonalcoholic fatty liver disease (NAFLD), insulin resistance and liver fibrosis are prevalent in individuals co-infected with HIV type 1 (HIV-1)/hepatitis C virus (HCV), even after HCV eradication. Our aim was to evaluate single nucleotide polymorphisms (SNPs) associated with advanced liver fibrosis in HIV-1/HCV co-infected patients. DESIGN/METHODS: In a cohort of 102 participants, we genotyped 16 SNPs in 10 genes previously associated with NAFLD and the innate immune response and correlated the genotypes with liver fibrosis and fat accumulation. RESULTS: Multinomial logistic regression analysis identified three metabolic parameters that were significantly associated with advanced liver fibrosis (stage F3-F4): albumin [odds ratio (OR) 0.80, 95% confidence interval (CI) 0.69-0.91, P = 0.001], percentage of visceral fat area (PVFA) (OR 1.06, 95% CI 1.01-1.12, P = 0.03) and BMI (OR 1.47, 95% CI 1.22-1.77, P < 0.0001). After adjustment for sex, albumin, PVFA and BMI, we found that three SNPs were significantly associated with advanced fibrosis, one each in PNPLA3/rs738409 (P = 0.016), ADAR-1/rs1127313 (P = 0.029) and IFIH1/rs1990760 (P = 0.033). CONCLUSION: Our results indicate that genotyping for these SNPs can be a useful predictive tool for liver fibrosis progression and liver fat accumulation in patients co-infected with HIV-1/HCV.

RESUMO

Our primary objective was to assess the independent association between liver fibrosis (LF) and abdominal fat accumulation (AFA) and fatty liver disease (FLD). We also aimed to determine the diagnostic accuracy of AFA and FLD for the prediction of cirrhosis measured using unenhanced low-dose computed tomography (CT). This is a cross-sectional study in stable human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients with active HCV replication. CT was used to quantify fat content in segments III and VI of the liver and AFA. Transient elastometry was used to stage LF. Multivariate logistic regression, receiver operating characteristic curve analysis, and linear mixed model analysis were applied. One hundred fifteen HIV/HCV-coinfected patients were included. Cirrhosis was detected in 20.8% (24 patients). There was a high correlation between anthropometric characteristics and radiological variables. The factors independently associated with cirrhosis were albumin concentration [odds ratio (OR), 0.69; 95% confidence interval (CI), 0.58-0.83; p < .0001] and visceral fat accumulation (OR, 1.02; 95% CI, 1.01-1.04; p = .0003). Multinomial analysis showed that visceral fat area (VFA) was the factor independently associated with stage F2 (OR, 1.02; 95% CI, 1.0-1.03; p < .005) and albumin concentration with stage F3 (OR, 0.75; 95% CI, 0.64-0.89; p < .001). VFA was the only radiological variable with an area under the curve >0.7 for the prediction of cirrhosis. There was no inter- or intraobserver variability in the measurement of AFA; however, high interobserver variability was recorded in the measurement of FLD. The association of VFA with cirrhosis, the high reproducibility of CT for the measurement of VFA, and the ability of VFA to predict cirrhosis make CT a suitable technique for identifying HIV/HCV-coinfected patients for closer surveillance.
