Study Design: Longitudinal study.
Objectives: To describe the severity of spinal cord injury/disease (SCI/D), type and management of neurogenic lower urinary tract dysfunction, tumor characteristics, and bladder cancer latency period in SCI/D patients.
Setting: Spinal cord injury centers in Germany, Austria, and Switzerland.
Methods: Data of SCI/D patients diagnosed with bladder cancer were collected between Jan 2012-Dec 2019 in the course of annual surveys in the neuro-urological departments of all 28 centers. Demographic and paralysis-specific data, data on the type and management of neurogenic lower urinary tract dysfunction, and histopathological tumor characteristics were collected.
Results: Regarding histopathological tumor characteristics, no significant differences were found in 135 individuals with SCI/D when stratified for bladder management without chronic catheterization, SCI/D severity, and ASIA classification. The mean latency period between the onset of SCI/D and the diagnosis of bladder cancer was significantly longer in patients with catheter-free emptying methods compared to patients with intermittent catheterization, and in patients with LMNL (Lower Motor Neuron Lesion) compared to patients with UMNL (Upper Motor Neuron Lesion).
Conclusions: Urinary bladder carcinomas are late events in the long-term course of SCI/D. Follow-up and approaches to screening must therefore be intensified with increasing duration of long-term SCI.

Although curcumin is a well-known natural polyphenol with many biological activities, its clinical application has been limited by low aqueous solubility and stability. Therefore, curcumin derivatives have been proposed to overcome these limitations and increase anticancer activity. This study tested curcumin derivatives with modified feruloyl moieties ( and ) and the β-diketo moiety () to better understand their anticancer mechanism against human bladder cancer cells.

The overexpression of the epidermal growth factor receptor (EGFR) in certain types of prostate cancers and glioblastoma makes it a promising target for targeted radioligand therapy. In this context, pairing an EGFR-targeting peptide with the emerging theranostic pair comprising the Auger electron emitter cobalt-58m (Co) and the Positron Emission Tomography-isotope cobalt-55 (Co) would be of great interest for creating novel radiopharmaceuticals for prostate cancer and glioblastoma theranostics. In this study, GE11 (YHWYGYTPQNVI) was investigated for its EGFR-targeting potential when conjugated using click chemistry to N1-((triazol-4-yl)methyl)-N1,N2,N2-tris(pyridin-2-ylmethyl)ethane-1,2-diamine (TZTPEN).

Despite the high incidence of bladder cancer (it represents the 7th most common cancer in males), EAU guidelines do not recommend any technique for screening and prevention, whereas the main diagnostic tools remain computed tomography urography (CTU), cytology, and cystoscopy. Unfortunately, these gold-standard modalities are mainly characterized by low sensitivity and accuracy. To minimize the limitations and increase the detection rates of urothelial cancer, several technologies have been developed.

The innate immune response serves as the primary defense against viral infections, with the recognition of viral nucleic acids by pattern recognition receptors (PRRs) initiating antiviral responses. Mitochondrial antiviral-signaling protein (MAVS) acts as a pivotal adaptor protein in the RIG-I pathway. Alternative splicing further diversifies MAVS isoforms.

Despite advances in prophylaxis, early diagnosis, and treatment, urogenital cancers represent a significant challenge to public health in Poland due to their relatively high prevalence and mortality rates. This narrative review aims to explore contemporary evidence on the epidemiology of urogenital cancers in Poland, such as prostate cancer, bladder cancer, kidney cancer, testicular cancer, and penile cancer, focusing on current and historical status and trends in the broader context of healthcare delivery. The literature consistently indicates that urogenital cancer continues to be a significant contributor to cancer incidence and mortality rates in Poland.
