Genotyping NAT2 with only two SNPs (rs1041983 and rs1801280) outperforms the tagging SNP rs1495741 and is equivalent to the conventional 7-SNP NAT2 g…

2011

Genotyping N-acetyltransferase 2 (NAT2) is of high relevance for individualized dosing of antituberculosis drugs and bladder cancer epidemiology. In this study we compared a recently published tagging single nucleotide polymorphism (SNP) (rs1495741) to the conventional 7-SNP genotype (G191A, C282T, T341C, C481T, G590A, A803G and G857A haplotype pairs) and systematically analysed if novel SNP combinations outperform the latter. For this purpose, we studied 3177 individuals by PCR and phenotyped 344 individuals by the caffeine test. Although the tagSNP and the 7-SNP genotype showed a high degree of correlation (R=0.933, P0.0001) the 7-SNP genotype nevertheless outperformed the tagging SNP wit…

Total, red and processed meat consumption and human health: an umbrella review of observational studies

2022

Meat consumption has represented an important evolutionary step for humans. However, modern patterns of consumption, including excess intake, type of meat and cooking method have been the focus of attention as a potential cause of rise in non-communicable diseases. The aim of this study was to investigate the association between total, red and processed meat with health outcomes and to assess the level of evidence by performing a systematic search of meta-analyses of prospective cohort studies. Convincing evidence of the association between increased risk of (i) colorectal adenoma, lung cancer, CHD and stroke, (ii) colorectal adenoma, ovarian, prostate, renal and stomach cancers, CHD and st…

Rectosigmoid Pouch (Mainz Pouch II) in Children

2005

Continent anal urinary diversion is a therapeutic option in bladder exstrophy. We report our long-term results with the rectosigmoid pouch (Mainz pouch II), a modification of the classic ureterosigmoidostomy.A total of 38 children with a mean age of 5 years (range 0.5 to 17) underwent a Mainz pouch II procedure between 1991 and 2004. Most patients (33) had bladder exstrophy or incontinent epispadias. In 14 children (37%) urinary diversion was performed after failed primary reconstruction. In 6 children conversion was performed from an incontinent type of urinary diversion. Renal function, continence and metabolic changes were analyzed. A total of 35 children were followed for a mean of 112 …

Venous thromboembolism in metastatic urothelial carcinoma or variant histologies: incidence, associative factors, and effect on survival.

2016

Venous thromboembolism (VTE) is common in cancer patients. However, little is known about VTE risk in metastatic urothelial carcinoma or variant histologies (UC/VH). We sought to characterize the incidence, associative factors, including whether various chemotherapy regimens portend different risk, and impact of VTE on survival in metastatic UC/VH patients. Patients diagnosed with metastatic UC/VH from 2000 to 2013 were included in this multicenter retrospective, international study from 29 academic institutions. Cumulative and 6-month VTE incidence rates were determined. The association of first-line chemotherapy (divided into six groups) and other baseline characteristics on VTE were anal…

Second-Line Chemotherapy in Advanced Bladder Cancer

Immunohistochemical expression of Ki-67, Cyclin D1, p16INK4a, and Survivin as a predictive tool for recurrence and progression-free survival in papil…

2019

Objectives: To investigate the expression of several immunohistochemical (IHC) markers and their predictive ability for the recurrence-free and progression-free survival of papillary urothelial bladder cancer (UBC) pTa/pT1 G2 (WHO 1973) compared to classical anatomo-clinical variables using a multidimensional analysis. Materials and Methods: A population-based cohort of 213 primary stage UBC (pTa/pT1) G2 (WHO 1973) was evaluated by classic anatomopathological variables and characterized by immunohistochemistry (23 IHC markers, representative of different oncogenic pathways). The most important variables as a predictor of recurrence-free and progression-free survival were selected using mult…

Gemcitabine and oxaliplatin combination chemotherapy in advanced biliary tract cancers

2006

Background Biliary tract cancers are uncommon tumors with a poor prognosis and most patients present with invasive and inoperable disease at diagnosis. Chemotherapy represents a palliative treatment, with poor response rates and a median survival of less than 6 months. Oxaliplatin and gemcitabine have shown an interesting activity as single agents in this group of patients. Patients and methods We carried out a multicenter phase II study to evaluate the efficacy and safety of combined oxaliplatin and gemcitabine in locally advanced and metastatic biliary tract carcinoma. The schedule of chemotherapy included oxaliplatin 100 mg/m2 on day 1 and gemcitabine 1000 mg/m2 on days 1 and 8, every 21…

Epidermal Growth Factor Receptor (EGFR) Cell Expression During Adjuvant Treatment After Transurethral Resection for Non-Muscle-Invasive Bladder Cance…

2019

Abstract Background The aim of the study was to investigate the feasibility of Epidermal Growth Factor Receptor (EGFR) measurement in bladder washings of patients affected by non–muscle-invasive bladder cancer (NMIBC) and its prognostic role in identifying risk subgroups and predicting disease recurrence and progression. Patients and Methods Patients with NMIBC treated with transurethral resection of bladder tumor (TURBT) from 2012 to 2015 were enrolled. Samples of bladder washings were collected and stored at −80°C until RNA extraction. The cDNA obtained from RNA was used to perform a gene expression analysis by a real time polymerase chain reaction. Results An adequate cellular pellet was…

Multiple Mucosal Biopsies and Postoperative Urinary Cytology in Patients with Bladder Cancer

1990

Seventy-one patients with bladder tumors of stage Ta, T1 or T2 were studied by bladder mucosal biopsies. In 34 (48%) patients abnormal histology was found in at least one of the biopsies. The occurrence and severity of mucosal abnormalities were related to tumor grade and stage. Urinary cytology after complete tumor resection was positive in 18 of 19 patients with abnormal biopsies and in 6 of 12 patients with normal biopsies. Postoperative urinary cytology seems to be a good indicator for the presence of urothelial atypia.
