Incidental diagnosis of bladder cancer in a national observational study in spain.

Introduction: Bladder cancer (BC) is a common malignancy in Spain. The aims of this study were: to identify the proportion of patients diagnosed with BC incidentally or after symptomatic presentation in a contemporary period in Spain; to compare demographic, clinical, and pathologic characteristics between these groups.

Methods: This was a retrospective analysis of a multi-centre observational study of 26 hospitals in the Spanish National Health System of all BCs newly diagnosed in 2011.

Is Tumor Budding a New Predictor for Early Cystectomy in pT1 High-Grade Bladder Cancer?

Unlabelled: Background & Objectives: We aimed to evaluate the risk of progression in high-grade T1 (HGT1) tumors using tumor budding (TB) and other standard clinical and histological features. TB is defined as an isolated cancer cell or a cluster composed of fewer than 5 cells scattered in the stroma and is usually used as a strong predictor of lymph node metastasis in T1 colorectal cancer.

Methods: This is an observational longitudinal cohort study involving 168 consecutive patients with HGT1 between 2013 and 2016.

Comparative analysis of the incidence of bladder cancer in the communities of Andalusia, Catalonia and Madrid in 2011.

Objectives: To determine the incidence of bladder cancer (BC) in the autonomous communities that include the largest number of cases in the national hospital BC registry (Andalusia, Catalonia and Madrid) and report the clinical, pathological and diagnostic differences and similarities of BC in these regions.

Material And Methods: An observational epidemiological study was performed in 2011 in 12 public hospitals with reference population areas according to the National Health System (Spain). Demographic and clinical variables were collected from new cases and relapses, with histopathologic confirmation of BC.
