The present study clearly demonstrates that CYP11B2 immunostaining is a powerful tool for histopathological diagnosis of aldosterone overproduction in PA and for subtype classification of APA, multiple APCCs, unilateral multiple adrenocortical micronodules, and diffuse hyperplasia.
Various systemic inflammatory response biomarkers are associated with oncological outcome. We evaluated the superiority of prognostic predictive accuracy between neutrophil-lymphocyte ratio (NLR) and lymphocyte-monocyte ratio (LMR), and the prognostic significance of their perioperative change in patients with bladder cancer undergoing radical cystectomy (RC). We retrospectively analyzed 302 patients who had undergone RC in four institutions. Comparison of predictive accuracy between NLR and LMR was performed using receiver operating characteristic curve analysis. Overall survival (OS) and cancer-specific survival (CSS) were assessed with the Kaplan-Meier method and Cox regression analysis. Preoperative and postoperative LMR showed higher predictive accuracy for OS than NLR did (p = 0.034). Applying a cutoff of 3.41, change in perioperative LMR stratified patients into three groups (low, intermediate, and high risk), showing a significant difference in OS and CSS (p < 0.001, each), and pathological outcomes. Multivariable analyses for OS and CSS showed that poor changes in LMR (high risk) were an independent prognostic factor (hazard ratio 5.70, 95 % confidence interval 3.49-9.32, p < 0.001; hazard ratio 4.53, 95 % confidence interval 2.63-7.82, p < 0.001; respectively). Perioperative LMR is significantly associated with survival in patients with bladder cancer after RC, and it is possibly superior to NLR as a prognostic factor.
We evaluated the complications of each procedure using the ESS for classification of technical difficulty. Based on the results of our retrospective study, nephrouretectomy should be upgraded as "very difficult" group according to the ESS. Appropriate grading by technical difficulty is beneficial for the prevention of complications from laparoscopic surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
