Combined assessment of peritumoral Th1/Th2 polarization and peripheral immunity as a new biomarker in the prediction of BCG response in patients with high-risk NMIBC.

Intravesical Bacille Calmette-Guérin (BCG) remains the most effective treatment for high-risk non-muscle-invasive bladder cancer (NMIBC), unfortunately there is no validated biomarker to predict clinical outcome. Here we tried to explore the possibility that a combination of the density of peritumoral infiltrating cells (Th1, Th2 and PD-L1) and the composition of peripheral immune cells (neutrophil and lymphocyte counts) could generate a more reliable prognostic biomarker. Twenty-two patients with high-risk NMIBC treated with BCG (10 BCG nonresponders and 12 BCG responders) were selected.

Bladder cancer: Present and future.

Bladder cancer has a high incidence and involves high associated morbidity and mortality. Since its initial clinical suspicion, early diagnostic confirmation and multimodal treatment involve different medical specialties. For this reason, we consider it important to spread the current consensus for its management.

Role of Inflammation in the Perioperative Management of Urothelial Bladder Cancer With Squamous-Cell Features: Impact of Neutrophil-to-Lymphocyte Ratio on Outcomes and Response to Neoadjuvant Chemotherapy.

Background: Neutrophil-to-lymphocyte ratio (NLR) might reflect an increased neutrophilic inflammatory response, and urothelial tumors with squamous-cell features (SqD) have been linked to inflammation. We hypothesized that NLR could be prognostic in these patients.

Patients And Methods: In patients with SqD muscle-invasive bladder cancer treated with curative intent, NLR and relationships with outcomes were analyzed by Cox regression, log-rank, and Kaplan-Meier analysis.

Low Pretreatment Neutrophil-to-Lymphocyte Ratio Predicts for Good Outcomes in Patients Receiving Neoadjuvant Chemotherapy Before Radical Cystectomy for Muscle Invasive Bladder Cancer.

Purpose: The pretreatment neutrophil-to-lymphocyte ratio (NLR) has been associated with cancer prognosis, influencing progression and chemosensitivity. We aimed to define the role of the NLR in predicting the outcomes to neoadjuvant chemotherapy (NAC) in patients with muscle invasive bladder cancer (MIBC).

Patients And Methods: The data from patients treated with NAC and radical cystectomy for MIBC from 2007 to 2015 at a tertiary care center were reviewed.

[Diode laser enucleation of the prostate (Dilep): technique and initial results].

Introduction: we present our preliminary experience and results of practising the prostate enucleation technique using a diode laser (DiLEP) and intravesical morcellation, following the same principles of holmium laser enucleation (HoLEP).

Materials And Method: we endoscopically treated benign prostate hyperplasia with DiLEP in 17 patients over a period of five months. They were all followed up for three months with flowmetry and IPSS.

[Holmium laser enucleation of the prostate. Experience in Hospital Germans Trias i Pujol].

Objectives: Evaluate the introduction of the enucleation with Holmium laser in our center, including the surgeon's learning curve by the analysis of the patients.

Materials And Methods: 150 procedures have been analyzed in a retrospective manner with an average follow-up of 11 months. Qmax, IPSS and Qol have been determined before surgery, at 6 months and 12 months, realizing their statistic analysis.

BRCA1 mRNA expression and outcome to neoadjuvant cisplatin-based chemotherapy in bladder cancer.

Background: neoadjuvant chemotherapy has shown a modest benefit in muscle-invasive bladder cancer patients; however, the subset of patients most likely to benefit has not been identified. BRCA1 plays a central role in DNA repair pathways and low BRCA1 expression has been associated with sensitivity to cisplatin and longer survival in lung and ovarian cancer patients.

Patients And Methods: we assessed BRCA1 messenger RNA expression levels in paraffin-embedded pre-treatment tumor samples obtained by transurethral resection from 57 patients with locally advanced bladder cancer subsequently treated with neoadjuvant cisplatin-based chemotherapy.

[Importance of the tissue polypeptide antigen level in neoplastic patients. Its correlation with other tumor markers].

In order to know the behavior of the tissue polypeptide antigen (TPA) as a tumor marker, the authors determine its amount in serum by means of radioimmunoassay (TPA Prolifigen RIA) in 441 patients having respiratory, digestive, urogenital, hematopoietic, mammary and other malignant tumors. The obtained results indicate that: TPA has no tumor specificity; however it increases in tumors without any other known tumor marker. TPA has no diagnostic value, but it is useful for the following up of digestive, mammary, respiratory, ovarian and testicular cancer; amounts of TPA comprised between 90 and 120 U/l are not specific and have no clinical significance; and it is very useful the simultaneous determination of CEA and TPA in the respiratory, digestive and mammary malignant neoplasms to help the clinical data in the evaluation of tumor mass (CEA) and tumor activity (TPA) without indication of tumor localization.
