Primary male genital melanomas are very rare; they are associated with high mortality and late detection. Scrotal melanoma is the least common presentation and only 23 cases have been reported. Herein, the authors present a 30-year-old patient with stage IIIC (T4b, N2a, M0) scrotal melanoma in order to report the characteristics, treatment, and outcome, as well as to emphasize the importance of examination of the genitals, education of patients about self-examination and destigmatizing genital lesions to increase the likelihood of earlier detection.

Simple Summary There is a clinical need for non-invasive methods to detect urogenital cancer, for which urine offers a promising liquid biopsy. Tumor DNA in urine originates from shedding of the local tumor, but may also be excreted transrenally as circulating DNA fragments from the bloodstream. To assess the origin of tumor-associated DNA in the urine of urogenital cancer patients, molecular tumor markers were tested in natural voided urine, and in urine samples in which contact with the local tumor was circumvented. The latter concerned nephrostomy urine of bladder cancer patients and catheter urine of cervical cancer patients. We demonstrated that tumor DNA in the urine of urogenital cancer patients results not only from the shedding of the local tumor, but also from transrenal excretion of circulating tumor DNA. This supports the great potential of urine as a diagnostic tool for cancer detection. Abstract In urogenital cancers, urine as a liquid biopsy for non-invasive cancer detection holds great promise for future clinical application. Their anatomical position allows for the local shedding of tumor DNA, but recent data indicate that tumor DNA in urine might also result from transrenal excretion. This study aims to assess the origin of tumor-associated DNA in the urine of 5 bladder and 25 cervical cancer patients. Besides natural voided urine, paired urine samples were collected in which contact with the local tumor was circumvented to bypass local shedding. The latter concerned nephrostomy urine in bladder cancer patients, and catheter urine in cervical cancer patients. Methylation levels of GHSR, SST, and ZIC1 were determined using paired bladder tumor tissues and cervical scrapes as a reference. Urinary methylation levels were compared to natural voided urine of matched controls. To support methylation results, mutation analysis was performed in urine and tissue samples of bladder cancer patients. Increased methylation levels were not only found in natural voided urine from bladder and cervical cancer patients, but also in the corresponding nephrostomy and catheter urine. DNA mutations detected in bladder tumor tissues were also detectable in all paired natural voided urine as well as in a subset of nephrostomy urine. These results provide the first evidence that the suitability of urine as a liquid biopsy for urogenital cancers relies both on the local shedding of tumor cells and cell fragments, as well as the transrenal excretion of tumor DNA into the urine.

Pregnancy presents unique obstacles to diagnosis and management of urologic disease. We present a case of a primigravid female with clot retention requiring evacuation in the operating room due to the avulsion of a bladder mass which prolapsed during labor. Tumor pathology demonstrated a low-grade spindle cell lesion positive for progesterone receptor (PR) and high mobility group A2 (HMGA2), suggestive of deep angiomyxoma versus a benign fibroepithelial polyp or inflammatory myofibroblastic tumor.

Cancer pain remains a significant clinical problem worldwide. Cancer pain causes are multifactorial and complex and varying with a variety of factors and processes related both to the tumor process and to the host itself. Even though the quality of pharmacologic pain management has improved in the last decades, 1 in 3 patients do not receive pain medication appropriate for the intensity of experienced pain. Chronic cancer pain in urologic patients has different traits, since this carcinoma might originate from various organ:, prostate, kidneys, adrenal glands, urinary bladder or the penis. Urogenital neoplasm very often metastasized into the bones (spine, pelvis and head bones) and they are associated with pathological fractures, hypercalcemia, and neurological deficits, which lead to a significant reduction in quality of life. Pain induced by bone metastases is nociceptive pain, but may also be associated with neuropathic pain if the tumor performs compression or invasion of the nerve, spinal cord or nerve plexus. In 70-90% of urological cancer patients pain can be adequately relieved by consistent adherence to the WHO cancer pain recommendations. However, additional pain relief therapies, such as radiation and psychosocial treatment of these patients have to be considered.

Background: This review is an update of a previously published review in the Cochrane Database of Systematic Reviews (2009, Issue 3).Tea is one of the most commonly consumed beverages worldwide. Teas from the plant Camellia sinensis can be grouped into green, black and oolong tea, and drinking habits vary cross-culturally. C sinensis contains polyphenols, one subgroup being catechins. Catechins are powerful antioxidants, and laboratory studies have suggested that these compounds may inhibit cancer cell proliferation. Some experimental and nonexperimental epidemiological studies have suggested that green tea may have cancer-preventative effects. Objectives: To assess possible associations between green tea consumption and the risk of cancer incidence and mortality as primary outcomes, and safety data and quality of life as secondary outcomes. Search methods: We searched eligible studies up to January 2019 in CENTRAL, MEDLINE, Embase, ClinicalTrials.gov, and reference lists of previous reviews and included studies. Selection criteria: We included all epidemiological studies, experimental (i.e. randomised controlled trials (RCTs)) and nonexperimental (non-randomised studies, i.e. observational studies with both cohort and case-control design) that investigated the association of green tea consumption with cancer risk or quality of life, or both. Data collection and analysis: Two or more review authors independently applied the study criteria, extracted data and assessed methodological quality of studies. We summarised the results according to diagnosis of cancer type. Main results: In this review update, we included in total 142 completed studies (11 experimental and 131 nonexperimental) and two ongoing studies. This is an additional 10 experimental and 85 nonexperimental studies from those included in the previous version of the review. Eleven experimental studies allocated a total of 1795 participants to either green tea extract or placebo, all demonstrating an overall high methodological quality based on 'Risk of bias' assessment. For incident prostate cancer, the summary risk ratio (RR) in the green tea-supplemented participants was 0.50 (95% confidence interval (CI) 0.18 to 1.36), based on three studies and involving 201 participants (low-certainty evidence). The summary RR for gynaecological cancer was 1.50 (95% CI 0.41 to 5.48; 2 studies, 1157 participants; low-certainty evidence). No evidence of effect of non-melanoma skin cancer emerged (summary RR 1.00, 95% CI 0.06 to 15.92; 1 study, 1075 participants; low-certainty evidence). In addition, adverse effects of green tea extract intake were reported, including gastrointestinal disorders, elevation of liver enzymes, and, more rarely, insomnia, raised blood pressure and skin/subcutaneous reactions. Consumption of green tea extracts induced a slight improvement in quality of life, compared with placebo, based on three experimental studies. In nonexperimental studies, we included over 1,100,000 participants from 46 cohort studies and 85 case-control studies, which were on average of intermediate to high methodological quality based on Newcastle-Ottawa Scale 'Risk of bias' assessment. When comparing the highest intake of green tea with the lowest, we found a lower overall cancer incidence (summary RR 0.83, 95% CI 0.65 to 1.07), based on three studies, involving 52,479 participants (low-certainty evidence). Conversely, we found no association between green tea consumption and cancer-related mortality (summary RR 0.99, 95% CI 0.91 to 1.07), based on eight studies and 504,366 participants (low-certainty evidence). For most of the site-specific cancers we observed a decreased RR in the highest category of green tea consumption compared with the lowest one. After stratifying the analysis according to study design, we found strongly conflicting results for some cancer sites: oesophageal, prostate and urinary tract cancer, and leukaemia showed an increased RR in cohort studies and a decreased RR or no difference in case-control studies. Authors' conclusions: Overall, findings from experimental and nonexperimental epidemiological studies yielded inconsistent results, thus providing limited evidence for the beneficial effect of green tea consumption on the overall risk of cancer or on specific cancer sites. Some evidence of a beneficial effect of green tea at some cancer sites emerged from the RCTs and from case-control studies, but their methodological limitations, such as the low number and size of the studies, and the inconsistencies with the results of cohort studies, limit the interpretability of the RR estimates. The studies also indicated the occurrence of several side effects associated with high intakes of green tea. In addition, the majority of included studies were carried out in Asian populations characterised by a high intake of green tea, thus limiting the generalisability of the findings to other populations. Well conducted and adequately powered RCTs would be needed to draw conclusions on the possible beneficial effects of green tea consumption on cancer risk.

Objective: To study and compare the national and regional incidences and risk of developing of neoplasms of individual urogenital sites using 2012 – 2014 reports from the National Cancer Registry Programme (NCRP) data. Materials and Methods: A number of incident cases, age-adjusted rates (AARs), and cumulative risk (0 – 64 years) pertaining to urogenital neoplasms, along with the ICD-10 codes, were extracted. Data on indicators, namely number of incident cases, AARs and one in a number of persons develop cancer were summarized for both the sexes in each of the cancer registries and presented region-wise in the form of ranges. Results: The proportion of all urogenital neoplasms in comparison to all cancers was 12.51% in women and 5.93% in men. Risk of development of urogenital cancers for women was maximum (1 in 50) in the North-eastern region, followed by Rural West, South, and North. For men, the risk of developing neoplasms of urogenital sites was highest (1 in 250). For the neoplasms of the renal pelvis and ureter, both the incidence and risk were quite low for all genders across all the regions. Cervical neoplasms had the highest incidence (4.91 – 23.07) among female genital neoplasms, while prostate had the highest incidence (0.82 – 12.39) among male genital neoplasms. Conclusion: Making people aware of urogenital neoplasms and their risk factors are important for the public health awareness point of view. Centers that deal with either management of urogenital cases or/and screening of genital neoplasms could serve as the designated centers for creating such awareness.

Introdução: A doença de Paget extramamária é constituída por adenocarcinoma da pele em áreas de glândulas apócrinas. Trata-se de neoplasia rara cujo tratamento cirúrgico aparenta resultados satisfatórios. Devido às altas taxas de recorrência, entretanto, as cirurgias são potencialmente mutilantes. O imiquimode é imunoestimulador tópico utilizado no tratamento de verrugas anogenitais e carcinomas in situ. Seu uso tem sido descrito na literatura científica para terapia da doença de Paget extramamária com resultados satisfatórios. Objetivo: Descrever a evolução de quatro casos de doença de Paget extramamária tratados com imiquimode, para avaliação da evolução e resposta terapêutica. Métodos: Foi realizado estudo retrospectivo em serviço de dermatologia da cidade de São Paulo com revisão de prontuários de todos os pacientes com diagnóstico de doença de Paget extramamária e tratados com imiquimode de janeiro de 2011 a julho de 2018. Resultados: Foram incluídos quatro pacientes, três com lesão vulvar e um com lesão em bolsa escrotal. Duas mulheres evoluíram com resolução total da doença, uma não apresentou alteração, e o homem evolui com regressão de 70% da lesão, sendo submetido à exérese cirúrgica de área consideravelmente menor do que a da lesão inicial. Conclusões: O imiquimode se apresenta como método terapêutico válido no tratamento da doença de Paget extramamária.

Management of genitourinary (GU) cancers is improving rapidly with the development of immunotherapy agents, especially anti-PD-1/anti-PD-L1 therapies. Large studies have shown better outcomes for the treatment of these patients, leading to new drug approvals and recent changes in standards of care in renal, prostate and bladder cancer. We performed a review of recent studies assessing efficacy of immuno-oncology therapies in GU cancers. New results are summarized and next ways of development of clinical research are discussed as the use of such therapies will soon be assessed in first-line or adjuvant settings.

Objective Unlike for bladder cancer, the impact of regional lymph node dissection for upper tract urothelial carcinoma is unclear. We explored whether patient survival was influenced by systematic regional lymph node dissection, using resection templates according to the main tumor location, during radical nephroureterectomy for upper tract urothelial carcinoma. Methods The systematic regional lymph node dissection group was defined as cases in which the dissection of nodes and surrounding tissues followed the established template, and the non-systematic regional lymph node dissection group as cases undergoing limited or no lymph node dissection. We performed radical nephroureterectomy on 98 consecutive patients with various stages of upper tract urothelial carcinoma from May 1994 to September 2014 at our institution. Of these, 77 patients with cTanyN0M0 of upper tract urothelial carcinoma undergoing radical nephroureterectomy were grouped into systematic regional lymph node dissection or non-systematic regional lymph node dissection cohorts according to the extent of dissection, and their outcomes compared. Results Forty-four patients were categorized as systematic regional lymph node dissection and 33 as non-systematic regional lymph node dissection, including 17 with more limited nodal dissection and 16 with no nodal dissection. Five-year recurrence-free survival and cancer-specific survival were significantly higher in the systematic regional lymph node dissection (93% and 94%, respectively) than in the non-systematic regional lymph node dissection group (75% and 77% recurrence-free survival and cancer-specific survival, respectively). Further, 5-year recurrence-free survival and cancer-specific survival of muscle-invasive upper tract urothelial carcinoma (pT2-4) were significantly higher in the systematic regional lymph node dissection (87% and 91%, respectively) than in the non-systematic regional lymph node dissection group (59% and 62%, respectively) (P = 0.0237 and P = 0.0224). Neither recurrence-free survival nor cancer-specific survival was significantly prolonged by systematic dissection in patients with pTis-1 histology. Conclusions Systematic regional lymph node dissection during radical nephroureterectomy for cTanyN0M0 upper tract urothelial carcinoma patients has a significantly beneficial impact on survival compared with patients undergoing more limited dissection, especially in the cases involving muscle invasion.

CONTEXT: The recent discovery of the existence of a human genitourinary microbiome has led to the investigation of its role in mediating the pathogenesis of genitourinary malignancies, including bladder, kidney, and prostate cancers. Furthermore, although it is largely recognized that members of the gastrointestinal microbiota are actively involved in drug metabolism, new studies demonstrate additional roles and the potential necessity of the gastrointestinal microbiota in dictating cancer treatment response. OBJECTIVE: To summarize the current evidence of a mechanistic role for the genitourinary and gastrointestinal microbiome in genitourinary cancer initiation and treatment response. EVIDENCE ACQUISITION: We conducted a literature search up to October 2018. Search terms included microbiome, microbiota, urinary microbiome, bladder cancer, urothelial carcinoma, renal cell carcinoma, kidney cancer, testicular cancer, and prostate cancer. EVIDENCE SYNTHESIS: There is preliminary evidence to implicate the members of the genitourinary microbiota as causative factors or cofactors in genitourinary malignancy. Likewise, the current evidence for gastrointestinal microbes in dictating cancer treatment response is mainly correlative; however, we provide examples where therapeutic agents used for the treatment of genitourinary cancers are affected by the human-associated microbiota, or vice versa. Clinical trials, such as fecal microbiota transplant to increase the efficacy of immunotherapy, are currently underway. CONCLUSIONS: The role of the microbiome in genitourinary cancer is an emerging field that merits further studies. Translating microbiome research into clinical action will require incorporation of microbiome surveillance into ongoing and future clinical trials as well as expansion of studies to include metagenomic sequencing and metabolomics. PATIENT SUMMARY: This review covers recent evidence that microbial populations that reside in the genitourinary tract—and were previously not known to exist—may influence the development of genitourinary malignancies including bladder, kidney, and prostate cancers. Furthermore, microbial populations that exist at sites outside of the genitourinary tract, such as those that reside in our gut, may influence cancer development and/or treatment response.

This review article aims to provide an overview on of diffusion-weighted MR imaging (DW-MR imaging) in the urogenital tract. Compared with conventional cross-sectional imaging methods, the additional value of DW-MR imaging in the detection and further characterization of benign and malignant lesions of the kidneys, bladder, prostate, and pelvic lymph nodes is discussed as well as the role of DW-MR imaging in the evaluation of treatment response.

Urogenital carcinoma is common in wild California sea lions ( Zalophus californianus) along the west coast of the US. From 1979 to 1994, this cancer was observed in 18% (66/370) of necropsied subadult and adult sea lions at The Marine Mammal Center in Sausalito, California. A retrospective review of records from 1 January 2005 to 31 December 2015 was performed to characterize prevalence and characteristics of cancer over this decade. Fourteen percent (263/1917) of necropsied sea lions had cancer, of which 90% (237/263) were urogenital carcinoma. The prevalence of urogenital carcinoma was significantly higher in adults compared to juveniles and subadults. Advanced-stage disease with metastases was identified histologically in 78% (182/232) of cases and was the cause of death in 95% (172/182) of these cases. Metastases were most common in lung and lymph nodes, and hydronephrosis, secondary to ureter obstruction by metastases, was identified in 62% (114/185) of animals with advanced disease. No significant temporal change in prevalence was detected over the decade, and this highly aggressive, fatal cancer remains common in stranded California sea lions.

Aim The aim of this study was to develop a risk scoring system specific to patients with bone metastasis of genitourinary cancer. Materials and methods This study included 180 patients with bone metastasis of three major types of genitourinary cancer: prostate cancer (n=111), renal cell carcinoma (n=43,), and urothelial carcinoma (n=26). Clinical factors at diagnosis of bone metastasis were evaluated to identify independent prognostic factors. Results Multivariate analysis showed that type of primary cancer, poor performance status, the presence of visceral metastases, high Glasgow prognostic score and elevated neutrophil-to-lymphocyte ratio were independently predictive of poor prognosis. Patients were able to be classified by the prognostic risk score into four prognostic groups with low, intermediate, high, and very high risk. Conclusion This risk scoring system could be useful for predicting survival of patients with bone metastasis of genitourinary cancer and in making decisions on appropriate treatments for them.

CONTEXT: The centralization of cancer care is associated with better clinical outcomes and may be a method for optimizing value-based health care systems. OBJECTIVE: To systematically review the literature regarding the impact of centralization of care on clinical outcomes for genitourinary malignancies. EVIDENCE ACQUISITION: A systematic review was conducted using Ovid and MEDLINE to identify studies between 1970 and 2018 reporting on the centralization of care for genitourinary malignancies. Prospective and retrospective studies were screened. EVIDENCE SYNTHESIS: There were no published randomized control trials (RCTs) on the centralization of care for genitourinary malignancies. Twenty-two retrospective studies met inclusion criteria. Centralization of radical cystectomy was the most studied. Care for bladder cancer, prostate cancer, penile cancer, testicular cancer, and renal cancer was reportedly associated with better morbidity and survival outcomes for patients treated at high-volume centers. However, evidence of better outcomes for centralization of care remains limited for penile, renal, and testicular cancers owing to the paucity of data and/or the lower incidence of these genitourinary malignancies. CONCLUSIONS: Care for genitourinary malignancies by high-volume providers was associated with greater utilization of cancer surgery, lower morbidity, and better survival outcomes. Centralization of care was most appropriate for complex procedures such as radical cystectomy when interpreted in the context of survival outcomes. Further research is needed to address the impact of centralizing care for all urologic malignancies with consideration of the associated costs and patient-reported measures, including quality of life and patient experience. PATIENT SUMMARY: We explored the evidence for moving major operations into larger centers. We focused on surgery for cancers of the bladder, prostate, testicle, penis, and kidney, and found that larger-volume hospitals had better survival outcomes and fewer complications when compared to smaller hospitals. The difference may be greatest for complex major surgeries such as radical cystectomy.

The genitourinary tract is a common site for new cancer diagnosis, particularly for men. Therefore, cancer-containing specimens are very common in surgical pathology practice. However, many benign neoplasms and nonneoplastic, reactive, and inflammatory processes in the genitourinary tract may mimic or cause differential diagnostic challenges with malignancies. Emerging clinicopathologic, immunohistochemical, and molecular characteristics have shed light on the pathogenesis and differential diagnosis of these lesions. This review addresses differential diagnostic challenges related to benign genitourinary tract lesions in the kidney, urinary bladder, prostate, and testis, with emphasis on recent advances in knowledge and areas most common in diagnostic practice.

Hemangiomas are common lesions, best known for their appearance in the liver. Their appearance in less common locations, such as the gastrointestinal and genitourinary tracts, is less well known. We will review the typical and atypical appearance of hemangiomas in these locations on sonography, CT, and MRI.

Introduction Male infertility (MI) has been widely associated with different comorbid conditions. The aim of this review is to summarize the available evidences investigating the link between MI cancer, chronic non-malignant conditions and overall health. Evidence acquisition A literature search has been conducted using the MEDLINE/PubMed and Scopus databases for English-language original and review articles and selecting publications from January 2007 to June 2017, although highly regarded older publications were also considered. The following key words and MeSH terms were combined: "male infertility," "semen analysis," "health," "comorbidities," "cancer," "metabolic syndrome," "diabetes," "hypertension," "cardiovascular diseases," and "mortality." Evidence synthesis Several studies supported a higher risk of testis cancer for patients with MI; conversely, controversial findings have been reported on the association between prostate cancer and MI. Beside urogenital malignancies, melanoma, bladder, thyroid and hematological malignancies have been also more frequently reported among infertile men. Large cohort studies supported a significant association between diabetes mellitus, metabolic disorders and MI. Similarly, the risk of developing cardiovascular diseases appears to be higher among infertile men. Of note, a significant association between semen alterations and the overall burden of comorbidities, as well as the overall mortality, has been reported. A common genetic background appears as the main pathophysiological link between infertility and other comorbidities. Conclusions Male infertility is a proxy of the overall male health status. Physicians should comprehensively assess men presenting for couple infertility and properly followed-up these patients given their higher risk of developing cancer.

Study Objective To review our local experience with urogenital rhabdomyosarcoma (RMS) to determine the most common clinical presentation(s). Design Retrospective case series of all female patients with urogenital RMS who presented to a tertiary pediatric hospital between 1996 and 2016. All institutional electronic pathology reports were screened for RMS and those that were pelvic in origin and occurred in female patients were included for further analysis. Seventeen cases of urogenital RMS in female patients were identified and reviewed. Setting This study was conducted at The Royal Children's Hospital in Melbourne, Australia. This is a tertiary referral center for the state of Victoria and surrounding areas, which services more than 1.5 million pediatric patients. Participants Female pediatric patients (ages 0-18 years) who presented to The Royal Children's Hospital with eventual pathologic tissue diagnosis of urogenital RMS. Main Outcome Measures The cases were reviewed for clinical presentation, duration of symptoms before initial presentation, time to tissue diagnosis, and outcomes of treatment. Results Of the 17 cases reviewed, 5 (29%) presented with perineal mass, 4 (24%) presented with each of abdominal mass and grape-like lesions/hemorrhagic mass at the introitus, 3 (18%) with nonspecific symptoms only, and 1 (6%) with vulvar inflammation. Conclusion The clinical presentation of urogenital RMS in women is heterogeneous, and the classically described presentation of grape-like lesions at the introitus and vaginal bleeding represents only a small proportion of clinical presentations. Awareness of other presentations, which appear to be more common than previously recognized, needs to be increased to ensure timely diagnosis and treatment.

The diagnosis and treatment of rare genitourinary tumors is inherently challenging. The Rare Diseases Act of 2002 initially defined a rare disorder as one that affects fewer than 200,000 Americans. The lack of widely available clinical guidelines, limited research funding, and inaccessible clinical trials often lead to difficulty with treatment decisions to guide practitioners in rendering effective care for patients with rare genitourinary cancers. This article will discuss basic tenets of diagnosis and treatment as well as recent developments and clinical trials in rare non-urothelial bladder cancers and penile squamous cell cancers.

Suspicious malignant supraclavicular lymphadenopathy provides a challenge for diagnosis and treatment. The wide variety of primary tumours that metastasise to this region should alert the clinician to look beyond the head and neck, particularly if it is the only site in the neck with suspected disease. As metastatic spread to these nodes from primaries not in the head and neck often indicates wide spread disease, neck dissection is controversial. In this article we review the lymphatic anatomy and discuss the investigation of supraclavicular lymphadenopathy. We discuss the evidence for the management of the neck in patients with subclavicular primary cancers (excluding lymphoma and melanoma) and the role of neck dissection.

The objectives of this innovative meeting were to discuss developments in the management of genitourinary cancer worldwide and how Italian clinicians could harness these innovations in their everyday practice. The 2-day meeting was divided into two sessions covering kidney and prostate cancer, and a large part was given over to the presentation and discussion of new recently presented data at major international congresses in 2012. There were no restrictions on content and all subjects from pathology, surgery and genetics to therapy and patient outcomes were covered.

C-Met is a receptor tyrosine kinase with multiple functions throughout embryonic development, organogenesis and wound healing and is expressed in various epithelia. The ligand of c-Met is Hepatocyte Growth Factor (HGF) which is secreted among others by mesenchymal stroma/stem (MSC) cells. Physiological c-Met functions are centred around processes that underly cellular motility and invasive growth. Aberrant c-Met expression and activity is observed in numerous cancers and makes major contributions to cell malignancy. Importantly, HGF/c-Met signaling is crucial in the context of communication between cancer cells and the the tumor stroma. Here, we review recent findings on roles of dysregulated c-Met in urogenital tumors such as cancers of the urinary bladder, prostate, and ovary. We put emphasis on novel aspects of cancer-associated c-Met expression regulation on both, HGF-dependent and HGF-independent non-canonical mechanisms. Moreover, this review focusses on c-Met-triggered signalling with potential relevance for urogenital oncogenesis, and on strategies to specifically inhibit c-Met activity.

Diffusion weighted magnetic resonance imaging (DW MRI) appears to hold promise as a non invasive imaging modality in the detection of early microstructural and functional changes of different organs. DW MRI is an imaging technique with a high sensitivity for the detection of a large variety of diseases in the urogenital tract. In kidneys DWMRI has shown promise for the characterization of solid lesions. Also in focal T1 hyperintense lesions DW MRI was able to differentiate hemorrhagic cysts from tumours according to the lower apparent diffusion coefficient (ADC) values reported for renal cell carcinomas. Promising results were also published for the detection of prostate cancer. DW MRI applied in addition to conventional T2 weighted imaging has been found to improve tumour detection. On a 3 T magnetic resonance unit ADC values were reported to be lower for tumours compared with the normal appearing peripheral zone. The combined approach of T2 weighted imaging and DW MRI also showed promising results for the detection of recurrent tumour in patients after radiation therapy. DW MRI may improve the performance of conventional T2 weighted and contrast enhanced MRI in the preoperative work up of bladder cancer as it may help in distinguishing superficial from muscle invasive bladder cancer which is critical for patient management. Another challenging application of DW MRI in the urogenital tract is the detection of pelvic lymph node metastases. As the ADC is generally reduced in malignant tumours and increased under inflammatory conditions reduced ADC values were expected in patients with lymph node metastases. © 2009 International Cancer Imaging Society.

Testicular cancer is one of the commonest cancers in men of working age, and is increasing in incidence in Europe and North America. One suggested mechanism of causation is that there is impaired differentiation of germ cells in the pre- or perinatal period, followed by malignant transformation in later life, possibly by a hormonal mechanism. Endocrine disrupting chemicals (EDCs) have been a major focus of interest for etiological research into testicular cancer because they interact with various hormonal pathways. Several EDCs including bisphenol A, phthalates, metals, polychlorinated biphenyls, and organochlorines have been investigated, but there are few studies and those that exist have not been able to assess exposure well. In addition, several studies, particularly those with better exposure assessment, have suggested that workers in electrical occupations have increased risks of testicular cancer. Electromagnetic radiation may have subthermal effects or may disrupt hormone release. Chronodisruption such as due to shift-work could potentially increase the risk of testicular cancer via disruption of hormonal cycles, but only one study has so far investigated this possibility. Lastly, solvent exposure, particularly to dimethylformamide, has been suggested to be associated with testicular cancer, but almost all these studies are based on job title only, with no specific assessment of solvent exposure. In conclusion, there is little evidence available on which to base definitive statements about occupational causes of testicular cancer. Future studies need to improve exposure assessment and develop ways to adjust for possible prenatal factors.

Introduction: Imaging studies are an integral and important diagnostic modality to stage, to monitor and follow-up patients with metastatic urogenital cancer. The currently available guidelines on diagnosis and treatment of urogenital cancer do not provide the clinician with evidence-based recommendations for daily practice. Objectives: To develop scientifically valid recommendations with regard to the most appropriate imaging technique and the most useful time interval in metastatic urogenital cancer patients undergoing systemic therapy. Methods: A systematic literature review was performed searching MedLine, Embase and Web of Science databases using the terms prostate, renal cell, bladder and testis cancer in combination with the variables lymph node, lung, liver, bone metastases, chemotherapy and molecular therapy, and the search terms computed tomography, magnetic resonance imaging and positron emission tomography were applied. A total of 11,834 records were retrieved from all databases. The panel reviewed the records to identify articles with the highest level of evidence using the recommendation of the US Agency for Health Care Policy and Research. Conclusions: Contrast-enhanced computed tomography remains the standard imaging technique for monitoring of pulmonary, hepatic and lymph node metastases. Bone scintigraphy is still the most widely used imaging technique for the detection and follow-up of osseous lesions. For clinical trials it might be replaced by either PET-CT or MRI of the skeletal axis. Response assessment for patients treated with cytotoxic regime is best performed by the RECIST/WHO criteria; treatment response to molecular triggered therapy is best assessed by CT evaluating decrease in tumor size and density. Cross-sectional imaging studies for response assessment might be obtained after each 2 cycles of systemic therapy to early stratify responders from non-responders.

Summary Background Indirect evidence suggests that prolonged treatment with warfarin might be associated with a decreased incidence of urogenital cancer. We aimed to assess this association in a large population-based study. Methods Beneficiaries of Saskatchewan Health who were eligible for prescription drug benefits and aged 50 years or over with no history of cancer since 1967 were enrolled into a nested, matched case-control study. 19 412 new cases of urogenital cancer diagnosed between Jan 1, 1981, and Dec 31, 2002, were identified by use of information from the Saskatchewan Cancer Agency registry. For each case, six controls, totalling 116 470, who were matched for age, sex, and time of diagnosis were selected randomly. Conditional logistic regression analysis was used to calculate adjusted incidence rates of urogenital cancer in relation to warfarin use. Findings Compared with men who never used warfarin, men with 4 years of warfarin use had an adjusted incidence rate of 0·80 (95% CI [0·65–0·99]). For warfarin use 76–100% of the time, the adjusted rate ratios were 0·80 (0·66–0·96) during year 2 preceding diagnosis of prostate cancer, 0·76 (0·62–0·94) during year 3, and 0·67 (0·53–0·86) during year 4. No significant association was found between warfarin and risk of other urogenital cancers. Interpretation Our results suggest that warfarin has an antitumour effect that is specific to prostate cancer. Further investigation, with more complete assessment of confounders and that addresses the effect of warfarin on mortality of prostate cancer, is warranted.

Perivascular epithelioid cell tumors (PEComas) are mesenchymal tumors composed of histologically, immunohistochemically, ultrastructurally, and genetically distinctive cells. PEComas have been described in different organs and are considered ubiquitous tumors. In this review we discuss recent informations related to PEComas in the genitourinary tract.

We integrated all the eligible studies and investigated whether the TNF-α 308G/A polymorphism correlates with urogenital cancer risk. Tumor necrosis factor-α (TNF-α) is a risk factor for some urogenital cancers; however, in prostate and bladder cancers the results are controversial. PubMed, EMBASE, Web of Science, the Cochrane Library, the Chinese Biomedical Literature Database, and the Wanfang Database were searched for all case-control studies on the relationship between the TNF-α 308G/A polymorphism and susceptibility to urogenital cancer between January 1994 and January 2015. The pooled odds ratio with 95% confidence interval was calculated to assess the associations. A total of 504 articles were found, 39 of which involved 11,613 cases and 12,542 controls that fulfilled the inclusion criteria. Overall, the TNF-α 308G/A polymorphism was significantly associated with the risk of urogenital cancer. In the subgroup analysis for different cancer types, significant associations were found in cervical cancer and urothelial carcinoma, while our meta-analysis indicated that there were no significant associations between the TNF-α 308G/A polymorphism and prostate, bladder, or renal cancers. When stratified by ethnicity, significant associations were observed in Caucasian populations, whereas no significant associations were found in African-Americans, Asians, or mixed populations. Furthermore, carriers of the -308A allele among the hospital-based case-control group were at a high risk of urogenital cancer. Our meta-analysis showed that the TNF-α 308G/A polymorphism was significantly associated with urogenital cancer risk, particularly in the Caucasian and hospital-based populations.

Multiparametric MR imaging (mpMRI) combine different sequences that, properly tailored, can provide qualitative and quantitative information about the tumor microenvironment beyond traditional tumor size measures and/or morphologic assessments. This article focuses on mpMRI in the evaluation of urogenital tract malignancies by first reviewing technical aspects and then discussing its potential clinical role. This includes insight into histologic subtyping and grading of renal cell carcinoma and assessment of tumor response to targeted therapies. The clinical utility of mpMRI in the staging and grading of ureteral and bladder tumors is presented. Finally, the evolving role of mpMRI in prostate cancer is discussed.

Background Hepatic resection of liver metastases of non-colorectal, non-neuroendocrine, and non-sarcoma (NCNNNS) primary malignancies seems to improve survival in selected patients. The aims of the current review were to describe long-term results of surgery and to evaluate prognostic factors for survival in patients who underwent resection of NCNNNS liver metastases. Methods We identified 30 full texts (25 single-center and 5 multicenter studies) published after year 1995 and published in English with a total of 3849 patients. For NCNNNS liver metastases, 83.4 % of these subjects were resected. Results No prior systematic reviews or meta-analyses on this topic were identified. All studies were case series without matching control groups. The most common primary sites were breast (23.8 %), genito-urinary (21.8 %), and gastrointestinal tract (19.8 %). The median 5- and 10-year overall survival were 32.3 % (range 19–42 %) and 24 % (indicated only in two studies, range 23–25 %), respectively, with 71 % of R0 resections. Conclusions There is evidence suggesting that surgery of NCNNNS metastases is safe, feasible, and effective if treatment is part of a multidisciplinary approach and if indication is based on the prognostic factors underlined in literature analysis.
