A RANDOMISED STUDY EVALUATING MAINTENANCE SCHEDULE IN EARLY ADJUVANT CHEMOTHERAPY FOR INTERMEDIATE RISK NON-MUSCLE-INVASIVE BLADDER CANCER

2008

ABSTRACT Introduction and Objective: Adjuvant intravesical chemotherapy or BCG immunotherapy after transurethral resection (TUR) is a standard treatment for non–muscle-invasive transitional cell cancer of the bladder (NMI TCCB) at intermediate risk. Although the clinical value of early intravesical adjuvant chemotherapy is well established, the optimal schedule regimen and the role of maintenance is still debated. Methods: Between May 2002 and August 2003, 577 patients, undergoing TUR for NMI TCCB, were recruited. All patients underwent TUR and early (within 6 hours) intravesical chemotherapy with epirubicin at the dose of 80 mg diluted in 60 ml of saline solution. When histology was availa…

Perioperative Chemotherapy in Poorly Differentiated Neuroendocrine Neoplasia of the Bladder: A Multicenter Analysis

2020

There is scant evidence about optimal management of poorly differentiated neuroendocrine carcinoma of the bladder (BNEC). We performed a multicenter retrospective study on BNEC patients from 13 Italian neuroendocrine-dedicated centers to analyze strategies associated with better outcomes. Mixed adeno-neuroendocrine carcinomas (MANEC) were included. We analyzed overall survival (OS) in the overall cohort, relapse-free survival (RFS) in radically operated patients and progression-free survival (PFS) in patients who received chemotherapy for metastatic disease. Fifty-one BNEC patients were included (male: 46, median age: 70 years). Overall, median OS was 16.0 months, radical tumor resection wa…

Orthotopic MAINZ pouch bladder substitution – long-term follow-up

2021

Introduction After radical cystectomy, orthotopic neobladder is one surgical strategy for urinary diversion. To assess the usefulness of an operation, long-term data are essential. We examined long-term complications and continence rates of orthotopic ileocecal (MAINZ pouch) bladder substitution. Material and methods Between 1986 and 2011, 193 patients underwent orthotopic MAINZ pouch bladder substitution. Until July 2000, ureter implantation was performed into the ascending colon through a submucosal tunnel technique (Goodwin-Hohenfellner). After July 2000, ureters were implanted into the terminal Ileum using the ileocecal valve to prevent reflux: the left spatulated ureter by an end-to-en…

The Giessen-Mainz-Frankfurt procedure: a new method for complex pelvic reconstruction for bladder exstrophy.

2001

In bladder exstrophy primary reconstruction remains the gold standard worldwide. Despite various types of osteotomies the permanent correction of pubic diastasis remains a challenge. In maxillofacial surgery callus distraction is a routine treatment for hypoplastic mandibles. Originally described by Ilizarov, this method provides stable and true bone lengthening after gradual distraction of an osteotomy site as long as the periosteum remains intact. In cooperation with the departments of maxillofacial surgery and orthopedics we used this technique to correct pubic diastasis and facilitate phallic reconstruction in a 4 1/2-year-old boy with bladder exstrophy who had previously undergone cont…

“Randomised, open-label, phase II trial of paclitaxel, gemcitabine and cisplatin versus gemcitabine and cisplatin as first-line chemotherapy in advan…

2005

The purpose of the study was to evaluate the antitumor activity and the safety of paclitaxel combined with gemcitabine and cisplatin in patients affected by advanced transitional cell carcinoma of the urothelium (TCC). Eighty-five patients affected by advanced TCC and measurable disease were randomized to receive either paclitaxel at dosage of 70 mg/m2, gemcitabine 1000 mg/m2 and cisplatin 35 mg/m2 on days 1 and 8 every 3 weeks (GCP) or gemcitabine 1000 mg/m2 on days 1, 8, 15 and cisplatin 70 mg/m2 on day 2 every 4 weeks (GC). All enrolled patients were considered evaluable for response and toxicity (intention to treat). The observed response rate was 43% for GCP and 44% for GC combination,…

Papaverine in Human Bladder Muscle

1989

It is generally assumed that drugs which induce relaxation of smooth muscles may be of clinical importance in some urological disorders; such drugs are indeed widely used, for example, in the therapy of unstable bladders or to facilitate the passage of ureteral stones. Recently, papaverine has been shown to be very effective, e.g., in relaxing smooth muscles of the corpus cavernosum penis, thereby inducing erections in many impotent men (Virag 1982). The purpose of this study is to determine the relaxing properties of papaverine in isolated muscle strips from the human detrusor and to evaluate its potential clinical importance.

Zschokkella hildae Auerbach, 1910: phylogenetic position, morphology, and location in cultured Atlantic cod.

2010

Abstract The myxozoan Zschokkella hildae Auerbach, 1910, was detected with a prevalence of 100% in cultured Atlantic cod, Gadus morhua L. aged 1+ from a culture facility on the west coast of Scotland. Sporogonic stages of Z. hildae, plasmodia producing 2–5 mature spores, were located predominantly in the collecting ducts and ureters of the kidney, and spores were present in the urine collected from the bladder. Less frequently, plasmodia were detected in the interstitial tissue of the kidney. The parasite prevalence in cultured fish was considerably higher than reported in wild fish but no obvious signs of pathology were detected. SSU rDNA sequencing and phylogenetic analysis showed that Z.…

Ultrasound-Guided Intramural Inoculation of Orthotopic Bladder Cancer Xenografts: A Novel High-Precision Approach

2013

Orthotopic bladder cancer xenografts are essential for testing novel therapies and molecular manipulations of cell lines in vivo. Current xenografts rely on tumor cell inoculation by intravesical instillation or direct injection into the bladder wall. Instillation is limited by the lack of cell lines that are tumorigenic when delivered in this manner. The invasive model inflicts morbidity on the mice by the need for laparotomy and mobilization of the bladder. Furthermore this procedure is complex and time-consuming. Three bladder cancer cell lines (UM-UC1, UM-UC3, UM-UC13) were inoculated into 50 athymic nude mice by percutaneous injection under ultrasound guidance. PBS was first injected b…
