Embryonal rhabdomyosarcoma is a rare cancer that often requires multimodality therapy to treat; however, these therapies can cause changes in the biology of the tumor. Several reports have documented pathologic changes but only recently have genetic changes been mapped. We present case of two separate synchronous primary rhabdomyosarcomas in a 17-month-old patient and discuss the pathophysiology and genetic changes that occur with treatment. We hypothesize that a genetic field defect arising in development of the urogenital sinus caused the tumors, but that treatment modalities may have caused genetic alterations changing clinical behavior of the tumors and responses to treatment...

Nanfu Deng, Nora M Haney, Taylor P Kohn, Alexander W Pastuszak, Larry I Lipshultz
PURPOSE OF REVIEW: Non-standard shift work schedules negatively impact the overall health of shift workers, and several studies have shown that shift work, specifically, is detrimental to urogenital health. The aims of this study are to systematically review the literature and determine the effect of shift work on the outcomes of hypogonadism, male infertility, lower urinary tract symptoms, and urogenital cancers. RECENT FINDINGS: Recent evidence supports associations between non-standard shift work and an increase in the frequency of prostate cancer and the severity of erectile dysfunction, lower urinary tract symptoms, and hypogonadal symptoms, as well as worsening of semen parameters and fertility...

Angiogenesis is one important hallmark of cancer progression which explains the relevance of developing methods to efficiently analyze the neo-angiogenic process. In this report we make use of the transgenic adenocarcinoma of the murine prostate (TRAMP) model, considered a good model for studying clinical prostate cancer progression, to describe in detail the methods used to study angiogenesis in this type of solid tumor development. In this report we provide step-by-step procedures on the basis of previous work in our laboratory for: the mouse urogenital sinus (UGS) collection; microdissection of the prostate; preparation of the prostatic samples for immunofluorescence (to analyze vascular density, morphology, maturation, functionality, hypoxia, and others); preparation of prostatic samples to histopathological analysis and/or immunohistochemistry; and endothelial and vascular mural cell sorting and isolation by fluorescent associated cell sorting (FACS) to further analysis (mRNA, protein, or other) or to maintain in culture...

Helminths include free-living and parasitic Platyhelminthes and Nematoda which infect millions of people worldwide. Some Platyhelminthes species of blood flukes ( Schistosoma haematobium, Schistosoma japonicum , and Schistosoma mansoni ) and liver flukes ( Clonorchis sinensis and Opisthorchis viverrini ) are known to be involved in human cancers. Other helminths are likely to be carcinogenic. Our main goals are to summarize the current knowledge of human cancers caused by Platyhelminthes, point out some helminth and human biomarkers identified so far, and highlight the potential contributions of phylogenetics and molecular evolution to cancer research...

The biology of masculinization is fundamentally important for understanding the embryonic developmental processes that are involved in the development of the male reproductive tract, external genitalia, and also the tumorigenesis of prostate cancer. The molecular mechanisms of masculinization are of interest to many researchers and clinicians involved in varied fields, including molecular developmental biology, cancer research, endocrinology, and urology. Androgen signalling is mediated by the nuclear androgen receptor, which has fundamental roles in masculinization during development...

The patterns of 5-methylcytosine (5mC) and its oxidized derivatives, 5-hydroxymethylcytosine, 5-formylcytosine, and 5-carboxylcytosine (5caC) are reportedly altered in a range of cancers. Likewise, Wilms' Tumor protein 1 (WT1), a transcription factor essential for urogenital, epicardium, and kidney development exhibits aberrant expression in multiple tumors. Interestingly, WT1 directly interacts with TET proteins that catalyze the enzymatic oxidation of 5mC and exhibits high affinity for 5caC-containing DNA substrates in vitro ...

Human pesticide exposure can occur both occupationally and environmentally during manufacture and after the application of indoor and outdoor pesticides, as well as through consumption via residues in food and water. There is evidence from experimental studies that numerous pesticides, either in isolation or in combination, act as endocrine disruptors, neurodevelopmental toxicants, immunotoxicants, and carcinogens. We reviewed the international literature on this subject for the years between 1990 and 2017...

Myiasis is the infestation of humans with dipterous larvae. Traditionally, myiasis was thought to affect individuals living in tropical regions, however, several cases in temperate zones have been reported. We encountered two patients with histories of malignancies that presented with complaints of myiasis, in Chicago, in the spring and summer of 2016. The first patient, a 54-year-old female with a history of breast cancer, presented with complaints of maggots infesting her postsurgical chest wounds. She was diagnosed with sepsis, cellulitis, and wound myiasis...

Stable cancer patients diagnosed with a pulmonary embolus or deep vein thrombosis are commonly referred to the emergency department for management. This practice strains an already overburdened emergency department and is associated with long wait times and poor disease/injection education for patients. This pilot study sought to determine if stable cancer patients with newly diagnosed cancer-associated thrombosis could be effectively managed by community-based pharmacists who followed an evidence-based protocol to prescribe and initiate low-molecular weight heparin therapy...

OBJECTIVE: Wilms' tumor (WT) is the most common malignant tumor in the children's urogenital system. MiR-190b was found to participate in the development and progression of several cancers. However, the molecular mechanism of miR-190b in WT is still unclear. PATIENTS AND METHODS: We detected the miR-190b in WT tissue samples compared to adjacent normal samples as well as in WT patients' blood sample compared to normal volunteers using qRT-PCR. With over-expression and knockdown of miR-190b in WT-derived cell line SK-NEP-1, we next studied cell proliferation, cell circle, apoptosis, invasion and migration abilities change caused by miR-190b ectopic expression...

Standard radiation therapy for cervical cancer consists of external beam radiation therapy followed by an intracavitary brachytherapy boost. When brachytherapy cannot be performed due to unfavorable anatomy or coexisting medical conditions, stereotactic body radiotherapy with the CyberKnife is another treatment option which is less invasive and can be performed in a shorter treatment time. We performed non-invasive therapy using the CyberKnife for five cases of urogenital cancer located in the cervix. The local tumor control was excellent with minimal toxicity...

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...
