Background: Survey for more accurate biomarkers for predicting and preventing the future recurrence in high risk patients is urgently needed. The transcription factor forkhead box-O3 (FOXO3) is a well-established tumor suppressor. Its phosphorylation (p-FOXO3) as well as deregulation is involved in cancer initiation, progression and drug resistance. Therefore, we proposed that p-FOXO3/FOXO3 ratio change may play important role in the bladder cancer recurrence.
Methods: Surgical specimens of cancer tissue were obtained from 75 patients with bladder cancer (30 of non-recurrent and 45 of recurrent). The relative expression levels of p-FOXO3/FOXO3 in cancer tissue were measured by immunohistochemistry (IHC) stain and graded according to stain intensity. The correlation p-FOXO3/FOXO3 with clinicopathological parameters and tumor recurrence was analyzed.
Results: For bladder cancer patients with tumor recurrence, higher tumor grade (82% vs 70%, P=0.04) and stage (≥II, 49% vs 33%, P=0.02) in these patients was seen. In IHC study of paired tumor tissues, 39 out of 75 (52%) patients have increased p-FOXO3/FOXO3 ratio and they are closely related to tumor grade (low grade vs high grade =29.4% vs 58.6%, P=0.01) but not related to stage (low stage vs high stage =46.5% vs 59.3%, P=0.26). Regarding to tumor recurrence, the p-FOXO3/FOXO3 ratio is significant higher in recurrent group than non-recurrent group patients (0.78±0.15 vs 1.25±0.11, P=0.03). As comparing the first recurrence and subsequent recurrence group patients, there is no difference in the level of p-FOXO3/FOXO3 ratio (1.25±0.11 vs 1.10±0.09, P=0.25). Interestingly, recurrent tumors in low grade bladder cancer patients have marked increased p-FOXO3/FOXO3 ratio than non-recurrent tumors (0.90±0.22 vs 0.15±0.12, P=0.02).
Conclusion: Increased p-FOXO3/FOXO3 ratio has been observed in bladder cancer patients with tumor recurrence and it is closely related to higher tumor grade. Low grade bladder cancer is high risk in recurrence when p-FOXO3/FOXO3 ratio increased. These results implicated that p-FOXO3/FOXO3 ratio can be applied as a useful marker for further treatment decision making and prognostic of tumor recurrence in bladder cancer patients.

: Diabetes mellitus (DM) is associated with worse surgical outcomes, and is a risk factor for bladder cancer and subsequent oncological outcomes. This study evaluated outcomes robot-assisted radical cystectomy (RARC) compared to open radical cystectomy (ORC) in patients with DM. : Data of adults ≥ 18 years old with DM who underwent radical cystectomy were extracted from the United States National Inpatient Sample database 2005-2018.

Bladder cancer (BC) is a prevalent urinary malignancy and muscle-invasive bladder cancer (MIBC) is particularly aggressive and associated with poor prognosis. One of MIBC features is the nuclear atypia. However, the molecular mechanism underlying MIBC remains unclear.

Exploration of molecular markers is an ongoing focus in the field of bladder cancer research. Based on data from public databases, was identified as upregulated in bladder urothelial carcinoma (BLCA); however, its exact function and regulatory mechanism in this context remain unclear. To investigate the clinical implications of , we examined its levels in 90 BLCA and adjoining normal tissue samples.

Arsenic (As) occurs naturally in different forms and oxidation states. Amongst them, inorganic arsenic (iAs) is classified as both genotoxic and carcinogenic whilst other organic arsenic species are considered less toxic. As in rice is mainly present in the form of iAs which therefore poses a health risk to populations that consume rice as a staple food.

Introduction: Approximately 75% of bladder cancer cases are non-muscle invasive at diagnosis. Drug development for non-muscle invasive bladder cancer (NMIBC) has historically lagged behind that of other malignancies. No treatment has demonstrated the ability to overcome drug resistance that ultimately leads to recurrence and progression.
