BACKGROUND: Based on ontogenetic-anatomic considerations, we have introduced total mesometrial resection (TMMR) and laterally extended endopelvic resection (LEER) as surgical treatments for patients with cancer of the uterine cervix FIGO stages I B1 - IV A. For a subset of patients with locally advanced disease we have sought to develop an operative strategy characterized by the resection of additional tissue at risk for tumor infiltration as compared to TMMR, but less than in LEER, preserving the urinary bladder function...

Urine may represent a convenient source of biomarkers for the early detection of prostate cancer (PCa) since contains secreted prostatic products and exfoliated tumor cells. Furthermore urine are easy to collect with non-invasive procedures and they are repeatable. Several urinary biomarkers for PCa have been proposed in the past but only one (PCA3) has been approved for clinical use and even this is not widely utilized in the routine practice. Most of these, particularly the proteins, were abandoned due to lack of confirmation...

BACKGROUND: Integrin-targeting radiopharmaceuticals have potential broad applications, spanning from cancer theranostics to cardiovascular diseases. We have previously reported preclinical dosimetry results of (68)Ga-NODAGA-RGDyK in mice. This study presents the first human dosimetry of (68)Ga-NODAGA-RGDyK in the five consecutive patients included in a clinical imaging protocol of carotid atherosclerotic plaques. Five male patients underwent whole-body time-of-flight (TOF) PET/CT scans 10, 60 and 120 min after tracer injection (200 MBq)...

Background/Objective: A post-bladder tumor resection dose of MMC can reduce non-invasive papillary (pTa) bladder cancer recurrences by up to 40%; this treatment is recommended in both the AUA and EUA non-muscle-invasive bladder cancer guidelines. A common complication of this treatment is eosinophilic cystitis. Symptoms range from mild urinary frequency and urgency to debilitating pain and dysuria. Currently, there is no established treatment algorithm for MMC-induced cystitis. Methods: Members of the Urologic Surgery Quality Collaborative (USQC), a group composed of over 160 private and academic urologists, met to discuss the management of patients with cystitis following MMC therapy...

The neutrophil-to-lymphocyte ratio (NLR) is an inflammation marker that has prognostic value for various tumors, but its prognostic value in urothelial carcinoma (UC) remains controversial. This meta-analysis investigated the prognostic value of NLR in UC. A systematic search was performed on PubMed, ISI Web of Science, and Embase for studies focusing on the association between NLR and clinical features or prognosis of UC and published until November 2016. Prognostic outcomes and clinical features were collected and analyzed...

Bladder cancer arises from the epithelial lining of the urinary bladder, and it is known as transitional cell carcinoma (TCC). Tobacco smoking is the main known contributor to urinary bladder cancer. However thirty percent of bladder tumors probably result from occupational exposure in the workplace to carcinogens. Immunotherapy by intravesicular delivery of Bacillus Calmette–Guérin (BCG) is used to treat and prevent the recurrence of superficial bladder cancer. Successful BCG immunotherapy for bladder cancer is associated with proper induction of T helper (Th)1 immunity...

Genomic analyses are defining numerous new targets for cancer therapy. Therapies aimed at specific genetic and epigenetic targets in cancer cells as well as expanded development of immunotherapies are placing increased demands on animal models. Traditional experimental models do not possess the collective features (cancer heterogeneity, molecular complexity, invasion, metastasis, and immune cell response) critical to predict success or failure of emerging therapies in humans. There is growing evidence, however, that dogs with specific forms of naturally occurring cancer can serve as highly relevant animal models to complement traditional models...

PURPOSE: Cytokeratin 20 (CK20) and insulin-like growth factor 2 (IGF2) were previously proposed to be elevated in clinical samples from patients with bladder cancer (BCa). A two cohort design validation study was used to assess the relevance for BCa detection by transcript quantitation of both markers in urine samples. Their diagnostic value was assessed in comparison with voided urine cytology (VUC). METHODS: RNA isolation was carried out using cellular sediments of urine samples from 196/103 histologically positive BCa patients, as well as 97/50 control subjects for the test (TC) and validation cohort (VC), respectively...

Polyps of the lower reproductive tract are found in 7.8-50% of women. It has been hypothesized that cytogenetic modifications on chromosomes 6, 7 and 12 as well as epigenetic factors involving enzyme and metabolic activities may cause polyps to develop. Cervical polyps found in 2-5% of cases are of low clinical significance and can cause, although rarely, post coital bleedings. Cervical polyps grow during pregnancy and mucorrhoea. Trans vaginal ultrasound (TVU) provides an excellent diagnostic technique to diagnose the size and the anatomic location of endometrial polyps (EPs)...

Penile metastasis is an extremely rare event and mainly originate from primary pelvic tumor sites such us urinary bladder, gastro-intestinal tract and prostate and more rarely from respiratory system, bone tumors and melanoma. Here we describe the unusual presentation of two bladder urothelial cancer metastatic to the penis with no relevant clinical symptoms. Namely, a 69 years-old man with a warthy lesions of the foreskin and the glans misunderstood for a condylomata that at histological and immunohistochemical analysis showed a bladder urothelial carcinoma; and a 71 years-old man with reddish skin lesion of the glans, a previous history of bladder and urethral carcinoma and histological pagetoid spread of urothelial cancer to the glans...

INTRODUCTION: Bladder cancer (BC) has varied clinical behavior in terms of recurrence and progression. Current pathological characteristics are insufficient to prognosticate the outcome of a given treatment. Cellular metabolic regulatory molecules, such as micro RNA (miRNA), could be a potential biomarker to prognosticate the treatment outcomes. MATERIALS AND METHODS: PubMed and Google Scholar databases were searched for publications from 1990 to 2016, related to miRNA biogenesis, its function, and role in the pathogenesis of bladder as well as other cancers...
