OBJECTIVES: The standard treatment for FIGO stage 1B1 cervical cancer is radical hysterectomy (RH) [1]. Indocyanine-green (ICG) is a drug injected within the cervical stroma to detect the sentinel lymph node (SLN) in cervical cancer [2,3]. ICG travels through the lymphatic channels in the lateral parametrium, which results enhanced with green, before reaching the SLNs. This could help identifying the surgical landmarks. The aim of this video is to propose a new approach to perform parametrial dissection as part of RH under the guidance of ICG...

Clinical heterogeneity of bladder cancer prognosis requires the identification of bladder tumors' molecular profile to improve the prediction value of the established and clinically used markers. In the present study, we have analyzed miR-221/222 cluster expression in bladder tumors and its clinical significance for patients' prognosis and disease outcome. The study included 387 tissue specimens. Following extraction, total RNA was polyadenylated at 3΄-end and reversed transcribed. SYBR-Green based qPCR assays were performed for the quantification of miR-221/222 expression...

Bladder cancer has a 60-70% recurrence rate most likely due to residual tumour left behind after a transurethral resection (TUR). Failure to completely resect the cancer can lead to recurrence and progression into higher grade tumours with metastatic potential. We present here a novel therapy to treat superficial tumours with the potential to decrease recurrence. The therapy is a heat-based approach in which bladder tumour specific single-walled carbon nanotubes (SWCNTs) are delivered intravesically at a very low dose (0...

The risk connotation of terminology in influencing decision-making should not be underestimated. For example, "superficial" T1HG bladder cancer has the same poor cancer-specific survival as that conferred by the "highest risk" prostate cancer (Gleason 10, T3b). Co-management of concomitant prostate cancer and non-muscle invasive bladder cancer requires a careful competing risk analysis by both the physician and patient. Herein, we detail how patients and physicians should be careful not to underestimate the risk attributed to "non-muscle invasive" bladder cancer...

Intravesical instillation of antitumor agents following transurethral resection of bladder tumors is the standard strategy for the treatment of superficial bladder cancers. However, the efficacy of current intravesical instillation is limited partly due to the poor permeability of the urothelium. We therefore aimed to develop a high-penetrating, target-releasing drug delivery system to improve the efficacy of intravesical instillation. PAMAM, a dendrimer, were conjugated with polyethylene glycol (PEG) to form PEG-PAMAM complex as a nanocarrier...

The sialyl-Tn (sTn) antigen is an O-linked carbohydrate chain aberrantly expressed in bladder cancer (BC), whose biosynthesis is mainly controlled by the sialyltransferase ST6GALNAC1. Treatment with Bacillus Calmette-Guérin (BCG) is the most effective adjuvant immunotherapy for superficial BC but one third of the patients fail to respond. A poorly understood correlation between the expression of sTn and BC patient's response to BCG was previously observed. By analyzing tumor tissues, we showed that patients with high ST6GALNAC1 and IL-6 mRNA expression were BCG responders...

CONTEXT: The incidence of urothelial carcinoma of the bladder (UCB) is lower in women; however, women tend to present with more advanced disease. To date, there is no quantitative synthesis of studies reporting gender-specific outcomes in non-muscle-invasive UCB. OBJECTIVE: To conduct a meta-analysis evaluating gender-specific differences in recurrence of non-muscle-invasive urinary bladder cancer (NMIBC). EVIDENCE ACQUISITION: An unrestricted systematic literature search of the MEDLINE, EMBASE, and Cochrane libraries was conducted...

BACKGROUND: Nowadays, the intravesical Bacillus Calmette-Guérin (BCG) instillation is the method of choice for the postsurgical treatment of high-grade nonmuscle-invasive bladder cancer , to reduce both recurrence rate and risk of progression. BCG is hypothesized to correct the immune system disequilibrium occurring during carcinogenesis, through an immunostimulation with detrimental effects for tumoral cells. Inflammation plays a crucial role in tumor progression. The deregulation of inflammasomes upon carcinogenesis underlines its importance both in physiologic and pathologic human conditions...

BACKGROUND: The independent prognostic role of squamous differentiation in pT1 bladder urothelial carcinoma has not been reported in previous studies. This article describes the impact of squamous differentiation on tumor recurrence and survival, and whether this histologic variant could indeed alter definitive treatment, based on single center-based retrospective data. METHODS: Totally, we retrieved (1)1449 histologically confirmed pT1 bladder urothelial carcinoma patients without histologic variants; (2)227 pT1 bladder urothelial carcinoma patients with squamous differentiation in our institution, from May 2004 to Oct 2015...

BACKGROUND: Urothelial bladder cancer (UBC) is the ninth most common cancer worldwide. In Italy, the prevalence of the disease is approximately 10%, making it the fourth most prevalent cancer in the country. The increase in prevalence requires continuous surveillance and care, resulting in a significant burden on Italian National Health Service, making any improvement to the strategy for diagnosing and treating this disease important to the medical and scientific community. The aim of this study was to evaluate the UBC cost of illness in the Italian context, collecting the total costs of the disease...

OBJECTIVE: Most of the ovarian cancers are diagnosed at advanced stages. As peritoneal carcinomatosis increases, especially when it extends to the diaphragm and intestinal mesos, probability of obtaining complete cytoreduction is reduced. Complete cytoreduction (residue zero: R0) is one of the main factors affecting survival [1-3]. Here we present a novel technique of stripping the peritoneal surfaces as a part of cytoreductive surgery in such cases. METHODS: A 55year-old woman diagnosed with peritoneal carcinomatosis was considered appropriate for primary cytoreduction after assessment of her thorax-abdominopelvic tomography, which revealed resectable intra-abdominal disease...

Disseminated Mycobacterium bovis is an uncommon side-effect of intravesical Bacillus Calmette-Guérin (BCG) therapy that may be mediated through Mycobacteraemia. This case report, of a 77-year-old man with a history of intravesical BCG therapy and recent cardiac surgery, highlights the need for patients with similar features on history, presenting with generalised symptoms, to have mycobacterial cultures included in their workup.

In the United States, the annual incidence of bladder cancer is approximately 70,000 new cases, with a mortality rate of approximately 15,000/year. The most common subtype (70%) of bladder cancer is superficial, namely hte non-muscle invasive disease form limited to the urothelium. The rate of progression and recurrence is up to 40 and 70%, respectively. Urothelial cell carcinoma of the bladder is typically treated with transurethral resection. The cancerous cells can float onto the adjacent epithelium, increasing the risk of recurrence...

Multidrug resistance (MDR) is a critical factor, which results in suboptimal outcomes in cancer chemotherapy. One principal mechanism of MDR is the increased expression of ATP-binding cassette (ABC) transporters. Of these, multidrug resistance-associated protein 3 (MRP3) and breast cancer resistance protein (BCRP) confer MDR when overexpressed in cancer cell lines. We measured the mRNA expression of MRP3 and BCRP in primary untreated bladder cancer specimens using reverse transcription-quantitative PCR (RT-qPCR) in comparison to normal bladder tissue...

INTRODUCTION: Urothelial carcinomas are the fourth leading cause of cancer in humans. Their incidence is increasing by more than 50% in 25 years. The superficial forms (70% cases) require a close active surveillance to identify frequent recurrences and progression to invasive stage. Our main goal was to identify prognostic molecular markers for bladder cancer that could be used alone or in combination in routine clinical practice. In this aim, we evaluated the capability of the BCA-oligo test based on a CGH array to correctly classify tumoral grade/stage...
