Imaging of urinary bladder hernias
2005
Lorenzo E. Bacigalupo1, Michele Bertolotto2, Filippo Barbiera3, Pietro Pavlica4, Roberto Lagalla3, Roberto S. Pozzi Mucelli2, Lorenzo E. Derchi1 Bacigalupo LE, Bertolotte M, Barbiera F, et al. erniation of the urinary bladder is not rare. It is usually considered that 1–3% of all inguinal hernias involve the bladder [1], and Iason [2], in 1944, reported an incidence of 10% in men older than 50 years. Most bladder hernias involve the inguinal and femoral canals, with the latter more frequent in women, and a predilection for the right side has been reported. However, herniations through ischiorectal, obturator, and abdominal wall openings have also been described. Any portion of the bladder m…
Use of tacrolimus and mycophenolate mofetil as induction and maintenance in simultaneous pancreas-kidney transplantation
2000
Clinical trials using quadruple immunosuppression that include the combination of tacrolimus and mycophenolate mofetil have been shown to reduce the incidence of acute rejection episodes in simultaneous pancreas-kidney (SPK) transplantation. In an attempt to obtain a low rejection rate without antibody induction therapy, we undertook a prospective study of combined tacrolimus and mycophenolate mofetil and steroids as primary immunosuppression for SPK transplantation. In this study, we analyzed 17 patients who received low-dose intravenous tacrolimus as induction therapy. This was combined with oral tacrolimus, mycophenolate mofetil, and steroids as the primary immunosuppression regimen. The…
Cytokeratin expression patterns in low-grade papillary urothelial neoplasms of the urinary bladder.
2003
BACKGROUND The differential expression patterns of cytokeratin 20 (CK20) and 34βE12 antigen in low-grade papillary urothelial tumors of the bladder are discussed. METHODS A retrospective study of 120 patients with low-grade papillary bladder tumors (45 neoplasms of low malignant potential and 75 low-grade WHO G1 carcinomas) was performed. All tumors were graded in accordance with the 1998 World Health Organization/International Society of Urological Pathology (WHO/ISUP) and 1999 WHO classifications. The mean follow-up was 76.6 months (range, 36–168 mos), considering for prognostic purposes the time to first recurrence, or relapse-free interval (RFI), and the total number of recurrent patien…
[18F]5-fluoro-2-deoxyuridine-PET for imaging of malignant tumors and for measuring tissue proliferation
2003
The nucleoside 5-fluoro-2-deoxyuridine is a pyrimidine analogue accumulating in proliferative cells. We prospectively evaluated biodistribution of the PET tracer [(18)F]5-fluoro-2-deoxyuridine (FdUrd), its value for imaging malignant tumors, and its correlation to both [(18)F]2-fluoro-2-deoxyglucose (FDG)-PET findings and histological proliferation indices. In 11 previously untreated patients (5 lung carcinoma; 3 soft tissue sarcoma; 2 gastrointestinal carcinoma; 1 non-Hodgkin lymphoma [NHL]), mean doses of 290 MBq FdUrd and 390 MBq FDG were administered intravenously on subsequent days. Static PET scans were initiated 50-70 min after administration and the mean standardized uptake values (…
Correlation between GP-170 expression, prognosis, and chemoresistance of superficial bladder carcinoma.
2003
To study GP-170 in superficial bladder cancer at initial diagnosis and at recurrence and to evaluate if intravesical chemoprophylaxis modifies the expression of GP-170 in tumor recurrences. GP-170 was retrospectively assessed in 160 patients affected by primary superficial transitional cell carcinoma of the bladder and followed for up to 10 years. Eighty-four patients (52.5%) recurred after transurethral resection (TUR). Adjuvant intravesical chemotherapy after TUR was adopted in 52 patients. The correlations between GP-170 and G-grade, T-category, risk of recurrence and of progression, and adoption of adjuvant intravesical chemotherapy were investigated. The correlations between variations…
p53 immunoreactivity in biopsy specimens of T1G3 transitional cell carcinoma of the bladder--a helpful parameter in guiding the decision for or again…
2000
The aim of this study was to determine whether p53 is helpful in making the decision to undergo cystectomy in T1, G3 transitional cell carcinoma (TCC) of the bladder, by prospectively comparing the p53 status of bladder biopsies with the histology and p53 status of the corresponding cystectomy specimens. From January 1996 to August 1997, 38 consecutive patients with T1G3 TCC at 6 different centres were enrolled into the study. Bladder biopsies and cystectomy specimens were examined with three different antibodies against p53. The p53 status of each bladder biopsy was compared with p53 status, tumour stage and grade of the cystectomy specimen. An independent evaluation of the histology and i…
[Conservative treatment of locally advanced bladder carcinoma: neoadjuvant chemotherapy, TUR and radiotherapy. Results in 40 patients]
1998
to assess the results of bladder preservation in infiltrating bladder cancer. The potential for neoadjuvant chemotherapy followed by extensive TUR and radiotherapy was investigated in 40 patients with T2-T4a G2-G3 bladder carcinoma.from 1983 to 1995, 40 patients were submitted to bladder-sparing treatment consisting of neoadjuvant chemotherapy, extensive, TUR and radiotherapy. Most patients had T3G3 cancer. Cystectomy was not performed due to patient" choice in 29 cases (72.5%), for severe pulmonary or cardiovascular disease in disease in 9 patients (22.5) and age over 80 in 2 (5%) patients. A deep TUR-biopsy was performed before and after chemotherapy and an extensive TUR was repeated at t…
Factors affecting recurrence and progression in superficial bladder tumours
1995
Prognostic factors in superficial bladder tumours are highly correlated with each other. In this study, their relative importance is examined and grouping of patients in three different prognostic groups suggested. 576 patients (from EORTC protocols 30790 and 30782) were analysed. They have been followed from 3 months to 8.6 years with a median of 4 years. 76 patients developed an invasive tumour (or = T2); the shortest time to invasion was 12 weeks, the longest was 6.6 years. Time from invasion to death ranged from 3 weeks to 4.4 years with a median of 2 years. Prognostic factors contributing to recurrence, invasion and survival were investigated: age, sex, size of largest tumour, number o…
High IL-22RA1 gene expression is associated with poor outcome in muscle invasive bladder cancer
2020
Abstract Background The cell surface interleukin 22 (IL-22) receptor complex is mainly expressed in epithelial and tissue cells like pancreatitis cells. Recent studies described that IL-22R was overexpressed in malignant diseases and was associated with a poor overall survival (OS). The role of IL-22RA1 gene expression in muscle invasive bladder cancer (MIBC) has not been investigated, yet. Objectives The aim of this study was to analyze the role of IL-22RA1 gene expression in patients with MIBC. Methods In a cohort of 114 patients with MIBC who underwent radical cystectomy, IL-22RA1 gene expression was analyzed with qRT-PCR and correlated with clinical parameters. Furthermore, Kaplan-Meier…
Cigarette Smoking and Drinking Water Source: Correlation with Clinical Features and Pathology of Superficial Bladder Carcinoma
2007
<i>Objective:</i> Water source and cigarette smoking are related to clinical characteristics and pathology of superficial transitional cell carcinoma of the bladder. <i>Methods:</i> Tumor number, dimension, G-grade, T-stage, recurrences, cigarette smoking and water supply were recorded in patients harboring Ta–T1 G1–3 transitional cell carcinoma of the bladder. <i>Results:</i> Of 577 patients, 61% had multiple and 36% recurrent tumors. Two hundred and forty-one patients (42%) were current smokers and 188 (33%) were former smokers. Bottled water was the only drinkable source for 249 (45%) patients, municipal water supply for 177 (32%), artesian wells for 3…
