Peritoneal regression grading score (PRGS) in peritoneal metastasis: how many biopsies should be examined?

Objectives: The four-tied peritoneal regression grading score (PRGS) is increasingly used to evaluate the response of peritoneal metastases (PM) to chemotherapy. The minimal number of peritoneal biopsies needed for PRGS determination remains unclear.

Methods: A prospective cohort of 89 PM patients treated with 210 pressurized intraperitoneal aerosol chemotherapy (PIPAC) cycles was investigated.

Feasibility, Safety, and Efficacy of Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC) for Peritoneal Metastasis: A Registry Study.

Introduction: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a novel drug delivery system with superior pharmacological properties for treating peritoneal metastasis (PM). Safety and efficacy results of PIPAC with cisplatin/doxorubicin or oxaliplatin from a registry cohort are presented.

Methods: IRB-approved registry study.

Treatment of carcinoma in situ of the urinary bladder with an alpha-emitter immunoconjugate targeting the epidermal growth factor receptor: a pilot study.

Purpose: Patients with carcinoma in situ (CIS) of the bladder refractory to bacillus Calmette-Guérin (BCG) treatment are usually treated with cystectomy. Therefore, new treatment options with preservation of the urinary bladder are needed. The objective of the study was to investigate the feasibility, safety and efficacy of a novel targeted alpha-emitter immunotherapy for CIS after BCG treatment failure.

Diagnosis, Treatment, and Outcome of Arterioureteral Fistula: The Urologist's Perspective.

Introduction: Arterioureteral fistula (AUF) is a rare but potentially life-threatening disease that primarily arises as a long-term complication in oncological patients who have permanent ureteral stenting. The incidence is rising. The objective of this study was to outline the risk factors for management and outcome of AUF in a large individual case series.

Human papilloma virus is not detectable in samples of urothelial bladder cancer in a central European population: a prospective translational study.

Background: Previous investigations on the association of human papillomavirus (HPV) and human bladder cancer have led to conflicting results. The aim of this study was to determine if low and high risk HPV play a role in the etiology of superficial low grade and invasive high grade urothelial carcinoma of the bladder.

Methods: We prospectively collected tumor samples of urothelial carcinoma of the bladder from 109 patients treated with transurethral resection or cystectomy, with bladder tissue from transurethral resection of the prostate serving as control.

Optimizing selective renal clamping in nephron-sparing surgery using the Nussbaum clamp.

Objectives: Selective clamping techniques are an attractive surgical option in nephron-sparing surgery. We describe the use of the Nussbaum clamp for this procedure and point out the advantages of this clamping technique.

Technical Considerations: The perirenal fat overlying the tumor is removed from the kidney.

Linkage of aggressive prostate cancer to chromosome 7q31-33 in German prostate cancer families.

It has been suggested that chromosome 7q32 contains genes that influence the progression of prostate cancer from latent to invasive disease. In an attempt to confirm this linkage to prostate cancer aggressiveness, 100 German prostate cancer families were genotyped using a panel of eight polymorphic markers on chromosome 7q. We used a multipoint allele sharing method based upon a likelihood ratio test implemented in GENEHUNTERPLUS v1.
