Acquiring fresh and well-characterized tumor tissue samples is critical for conducting high-quality "omics" studies. However, it can be particularly challenging in the context of prostate cancer (PC) due to the unique nature of this organ and the high heterogeneity associated with this tumor. On the other hand, histopathologically characterizing samples before their storage without causing significant tissue alterations is also an intriguing challenge.

Depending on the invasiveness of tumors, patients with BC will undergo surgery and surveillance lifelong, owing the high rate of recurrence and progression. In this context, the development of strategies to support non-invasive BC diagnosis is focusing attention.

Cancer treatment in eldery people is challenging due to fragility and comorbidities of these patients. To meet the needs of treating UN in the eldery, it is necessary to optimize healthcare resources, for which a deep analysis of cancer registries becomes mandatory.
View Article and Find Full Text PDFBladder cancer (BC) represents a clinical, social, and economic challenge due to tumor-intrinsic characteristics, limitations of diagnostic techniques and a lack of personalized treatments. In the last decade, the use of liquid biopsy has grown as a non-invasive approach to characterize tumors. Moreover, the emergence of omics has increased our knowledge of cancer biology and identified critical BC biomarkers.
View Article and Find Full Text PDFPatients with non-muscle invasive bladder cancer (NMIBC) undergo lifelong monitoring based on repeated cystoscopy and urinary cytology due to the high recurrence rate of this tumor. Nevertheless, these techniques have some drawbacks, namely, low accuracy in detection of low-grade tumors, omission of pre-neoplastic lesions and carcinomas in situ (CIS), invasiveness, and high costs. This work aims to identify a urinary metabolomic signature of recurrence by proton Nuclear Magnetic Resonance (H NMR) spectroscopy for the follow-up of NMIBC patients.

A prospective study was done, 106 patients, 57 had previously been diagnosed with urological chronic pelvic pain (UCPP)/interstitial cystitis (IC) and 49 patients with gynaecological chronic pelvic pain (GCPP). Neoplastic cells cultures were exposed to the urine of patients with UCPP/IC and patients with GCPP.

The study of bladder cancer (BC) metabolism could be the key to developing new strategies for diagnosis and therapy. This work aimed to identify tissue and urinary metabolic signatures as biomarkers of BC and get further insight into BC tumor biology through the study of gene-metabolite networks and the integration of metabolomics and transcriptomics data.
View Article and Find Full Text PDFNon Muscle Invasive Bladder Cancer (NMIBC) is among the most frequent malignant cancers worldwide. NMIBC is treated by transurethral resection of the bladder tumor (TURBT) and intravesical therapies, and has the highest recurrence rate among solid tumors. It requires a lifelong patient monitoring based on repeated cystoscopy and urinary cytology, both having drawbacks that include lack of sensitivity and specificity, invasiveness and care costs.

Aim: The aim of our study was to assess the cardiovascular (CV) risk profile in a cohort of lupus patients with preserved kidney function after a nephritis episode, compared to patients without a nephritis flare.
Objective: To determine whether the apoptotic effect test could serve as a biomarker of severity in bladder pain syndrome/interstitial cystitis.
Material And Methods: A prospective study was conducted between January 2010 and January 2015, which included 57 patients diagnosed with interstitial cystitis and 49 diagnosed with chronic pelvic pain of gynaecological origin. The urine was exposed to cell cultures, and the urine's capacity for inducing apoptosis in the cultures was analysed.
Objective: To determine whether the number and percentage of positive biopsy cores identify a Gleason 3+4 prostate cancer (PC) subgroup of similar biologic behaviour to Gleason 3+3.
Material And Method: An observational post-radical prostatectomy study was conducted of a cohort of 799 patients with localised low-risk (n=582, Gleason 6, PSA <10ng/ml and cT1c-2a) and favourable intermediate PC (n=217, Gleason 3+4, PSA ≤10 ng/ml and pT2abc). The Gleason 3+4 tumours were stratified by number (≤3 vs.
Prostate cancer (PCa) is the second most common cancer among men worldwide. Its etiology remains largely unknown compared to other common cancers. We have developed a risk stratification model combining environmental factors with family history and genetic susceptibility.

Material And Methods: The implementation of the Lean Healthcare methodology in a urology department was conducted in 3 phases: 1) team training and improvement of feedback among the practitioners, 2) management by process and superspecialisation and 3) improvement of indicators (continuous improvement). The indicators were obtained from the Hospital's information systems.
Introduction: The main objective of the study was to assess the apoptotic effect of urine from patients with interstitial cystitis (IC) in cell cultures and to study its value as a diagnostic biomarker for IC.
