Background: To evaluate the risk factors for invasive bladder cancer and to develop a predictive model for the improvement of individual comprehensive therapy for invasive bladder cancers.
Materials And Methods: The records of 356 patients with invasive bladder cancer, operated on at three Chinese medical institutes, were reviewed. The Cox proportional hazards regression model was used to assess the clinical and pathological variables affecting disease-free survival (DFS). The regression coefficients determined by Cox regression analysis were used to construct a predictive index (PI). PI was used to categorize the patients into different risk groups. Kaplan-Meier survival curves followed with log-rank test were plotted to compare the difference.
Results: Tumor configuration (RR = 1.60, P = 0.01), multiplicity (RR = 1.41, P = 0.04), histological subtype (RR = 2.13, P < 0.01), tumor stage (RR = 2.50, P < 0.01), tumor grade (RR = 2.35, P < 0.01), node status (RR = 2.48, P < 0.01), and neoadjuvant chemotherapy (RR = 0.46, P = 0.02), had independent prognostic significance for DFS. PI = 0.47 x (configuration) + 0.34 x (multiplicity) + 0.76 x (tumor histological subtype) + 0.92 x (stage) + 0.86 x (grade) + 0.91 x (node status) - 0.79 x (neoadjuvant chemotherapy). The range of PI was -0.32 to 6.52, which was equally divided into three risk groups with significant differences on Kaplan-Meier curves and a log-rank test (P < 0.01). Meanwhile, the patient's probability of survival could be calculated by PI.
Conclusions: Seven factors (tumor configuration, multiplicity, histological subtype, tumor stage, tumor grade, node status, neoadjuvant chemotherapy) affect the prognosis after radical cystectomy (RC) for invasive bladder cancer. PI can be used to optimize the individual comprehensive therapy. Given fewer perioperative complications, fast recovery from surgery and relatively satisfactory quality of life, ureterocutaneostomy, and ileal conduit are suitable for the patients with short expected life spans.

Background: The prognosis for urothelial carcinoma remains poor, with limited therapeutic options, emphasizing the need for further research into targeted therapies. The prognostic and predictive significance of human epidermal growth factor receptor 2 (HER2) expression in urothelial carcinoma remains unclear, with previous studies reporting conflicting results.
Methods: We conducted a retrospective analysis of advanced urothelial carcinoma cases diagnosed between January 2017 and December 2022.
Background: Radical cystectomy has the potential to be a curative strategy for patients with aggressive bladder cancer. Emerging evidence over the last 20 years has shown that minimally invasive surgical approaches using robotics in performing this highly complex and morbid operation can achieve the same oncological outcomes while reducing complications for the patient.
Objective: This paper aims to present a managerial and leadership roadmap for change to robotic cystectomy for patients with advanced bladder cancer to achieve improved patient outcomes while embracing technological developments in the delivery of cancer care.

Introduction: Gastropod hemocyanins are potent immunostimulants in mammals, a trait associated with their large molecular size and unusual glycosylation patterns. While the hemocyanin from the marine snail keyhole limpet (KLH), has been widely studied and successfully employed as a carrier/adjuvant in several immunological applications, as well as a non-specific immunostimulant for bladder cancer treatment, few other gastropod hemocyanins have been biochemically and immunologically characterized. In this work, we investigated the immunogenic properties of the hemocyanin from (PcH), an invasive south American freshwater snail.

Background And Objective: Bladder cancer (BC) represents a significant health care challenge and is frequently detected during evaluations for haematuria in emergency departments (EDs). Our aim was to evaluate the clinical performance and economic implications of the Xpert BC Detection (BCD) test for patients presenting to the ED with haematuria to address the pressing need for more efficient and accurate diagnostic tools in this setting.
Methods: We conducted a prospective single-centre observational study in the ED of a tertiary university hospital.

As an antibody-drug conjugate (ADC), disitamab vedotin (RC48) is a promising treatment targeting ERBB2 for locally advanced and metastatic bladder cancer (BLCA). However, the subtype heterogeneity of muscle-invasive bladder cancer (MIBC) often leads to different therapeutic outcomes. In our study, we aim to explore sensitivity differences and mechanisms of different molecular subtypes of MIBC to RC48 treatment and develop a strategy for combination therapy against cancer.
