Abstract
Late relapses of Wilms tumour are extremely uncommon but still represent possible events. Even more rarely Wilms tumours present as extrarenal neoplasms, for which it could be difficult to diagnose and treat them promptly.We present a unique case of late recurrence of Wilms tumour 16 years after the primary diagnosis, with location in the gynaecological system. The relapse presented as a vaginal mass, and it gradually raised up to involve the majority of pelvic organs. We accurately studied the tumour extension, even realising a 3D preoperative reconstruction, and we managed to evaluate the patient with a multidisciplinary team involving general surgeons, urologists, gynaecologists and plastic surgeons. We finally decided for an extended surgical approach and realised a complete pelvic exenteration. Three months after surgery, the patient is in a good general condition, without major surgical complications and with no radiological signs of pelvic tumour relapse.

Abstract
Extrarenal Wilms tumor (ERWT) is rare, and its occurrence in the adult recto-vaginal septum is even more uncommon. Importantly, instances of a BRCA2 gene mutation associated with ERWT have not been documented. In this report, we present an unusual case of ERWT situated in the recto-vaginal septum of a 49-year-old woman, accompanied by a concurrent BRCA2 gene mutation. After the tumor's second recurrence, the patient experienced symptomatic relief after administering poly (ADP-ribose) polymerase (PARP) inhibitor therapy. Given the limited exposure and understanding of optimal treatment strategies for this distinct tumor, there is a definite need to accumulate further clinical experiences and insight. Consequently, we propose that genetic testing be considered in cases involving tumor recurrence or metastasis, since this may offer valuable information for identifying targets for therapeutic intervention.

Abstract
Retroperitoneal extrarenal Wilms tumor is a rare condition in children that can be easily misdiagnosed as other retroperitoneal malignancies unrelated to the renal origin. Computerized tomography scan plays a crucial role in diagnosing and distinguishing retroperitoneal malignancies. In this report, we present two cases of retroperitoneal extrarenal Wilms tumor in children who were admitted due to abdominal mass. Laboratory examination did not reveal any significant abnormality. However, a computerized tomography scan revealed a solid or cystic-solid mass in the retroperitoneum accompanied by a bone spur extending from the anterior edge of the vertebral body to the back of the mass, while the origin of the tumor remained unclear. By analyzing these two cases and reviewing previous studies on retroperitoneal extrarenal Wilms tumor in children, we summarized the clinical and imaging characteristics of this rare condition. We also found that the presence of a spinal deformity adjacent to the mass might indicate the possibility of a retroperitoneal extrarenal Wilms tumor.

Abstract
BACKGROUND Circular RNA (circRNA) has been shown to play an essential role in cancer progression, including nephroblastoma. Hsa_circ_0093741 was discovered to be highly expressed in nephroblastoma. However, its function and mechanism in nephroblastoma development are still vague. METHODS The expression levels of hsa_circ_0093741, miR-562 and FRS2 (Fibroblast Growth Factor Receptor Substrate 2) were detected using western blotting and quantitative real-time polymerase chain reaction. Functional experiments were performed by using cell counting kit-8, colony formation, 5-ethynyl-2'-deoxyuridine (EdU), transwell, scratch assays in vitro and animal experiments in vivo. The interaction analysis was conducted using dual-luciferase reporter assay and RIP assay. RESULTS Hsa_circ_0093741 was highly expressed in nephroblastoma tissues and cells. Functionally, hsa_circ_0093741 silencing significantly suppressed the growth, invasion, and migration of nephroblastoma cells in vitro. MiR-562 was decreased in nephroblastoma, and was validated to be a target of hsa_circ_0093741. Inhibition of miR-562 reversed the anticancer functions of hsa_circ_0093741 silencing on nephroblastoma cells. FRS2 expression was increased in nephroblastoma and served as a target of miR-562, moreover, FRS2 overexpression attenuated the inhibitory functions of miR-562 on the nephroblastoma cell malignant phenotypes mentioned above. Pre-clinically, lentivirus-mediated hsa_circ_0093741 silencing also impeded nephroblastoma tumor growth and metastasis in vivo. CONCLUSION Knockdown of hsa_circ_0093741 suppresses nephroblastoma cell growth, migration and invasion by regulating the miR-562/FRS2 axis, suggesting the potential involvement of hsa_circ_0093741 in nephroblastoma progression.

J Cell Physiol 2021; 236:5757-5770.

Abstract
Nephroblastoma, a pediatric kidney cancer, caused by pluripotent embryonic renal precursors. Long noncoding RNAs (lncRNAs) are commonly abnormal expressed in many cancers. In the present study, we fousced on one newly discrovered lncRNA, MYLK Antisense RNA 1 (MYLK-AS1), and its functional role in proliferation and cycle distribution of nephroblastoma cells. Micorarray-based analysis revealed the highly expressed Cyclin E1 (CCNE1) and MYLK-AS1 in nephroblastoma. After nephroblastoma tissue sample collection, RT-qPCR confirmed the upregulated expression of MYLK-AS1 and CCNE1 in nephroblastoma tissues and cells. Kaplan-Meier curve exhibited that patients with elevated CCNE1 had lower overall survival rate in follow-up study. RNA binding protein immunoprecipitation, chromatin immunoprecipitation, and dual-luciferase reporter gene assay were employed to determine the relationship among MYLK-AS1, TCF7L2, and CCNE1, which validated that transcription factor 7-like 2 (TCF7L2) could specifically bind to MYLK-AS1 and TCF7L2 could positively promote CCNE1. After gain- and loss-of function assays, the conclusion that silencing of MYLK-AS1 could inhibit expression of CCNE1 through the transcription factor TCF7L2 to regulate the cell proliferation and cell cycle distribution of nephroblastoma cells was obtained. Subsequently, the subcutaneous tumor formation ability of nephroblastoma cell in nude mice was observed and the silencing of MYLK-AS1 exerts suppressive role in the tumorigenic ability of nephroblastoma cells in vivo. Taken together, MYLK-AS1 constitutes a promising biomarker for the early detection and treatment of nephroblastoma.

Abstract
Background Wilms’ tumor is also called nephroblastoma and is the most common pediatric renal cancer. Several genetic and epigenetic factors have been found to account for the development of Wilms’ tumor. MiRNAs play important roles in this tumorigenic process. In the present study, we aimed to investigate the role of miR-140-5p in nephroblastoma by identifying its targets, as well as its underlying molecular mechanism of action. Methods The miRNA expression profile of nephroblastoma samples was investigated and the targets of miR-140-5p were predicted and validated using the miRNA luciferase reporter method. Moreover, the roles of miR-140-5p in regulating nephroblastoma cell proliferation, migration and cell cycle were analyzed by the CCK8, migration and flow cytometry assays, respectively. The downstream protein of the direct target of miR-140-5p was also identified. Results miR-140-5p was downregulated in Wilms’ tumor tissues, whereas in the nephroblastoma cell lines G401 and WT-CLS1 that exhibited high levels of miRNA-140-5p, inhibition of cellular proliferation and metastasis were noted as well as cell cycle arrest at the G1/S phase. TGFBRI and IGF1R were identified as direct target genes for miRNA-140-5p. In addition, SMAD2/3 and p-AKT were regulated by TGFBRI and IGF1R separately and participated in the miRNA-140-5p regulatory network. Ectopic expression of TGFBR1 and IGF-1R could abrogate the inhibitory effect of miR-140-5p. Conclusion We demonstrated that miRNA-140-5p participates in the progression of Wilms’ tumor by targeting the TGFBRI/SMAD2/3 and the IGF-1R/AKT signaling pathways.

Abstract
Extrarenal nephroblastoma (ERNB) is a rare disease. We report a case of ERNB in a 4-year-old boy complaining of abdominal pain and vomiting. Imaging showed a retroperitoneal mass and left hydronephrosis. The mass was completely removed by surgery. The pathologic diagnosis was ERNB with favorable histology. Postoperative chemotherapy was administered for 24 weeks with actinomycin D, vincristine, and doxorubicin. No signs of recurrence were found for the next 3 years. We consider 53 reports of ERNB and our own. Median age at diagnosis was 42 months. The most common site is the retroperitoneal space (44.4%), followed by the uterus (14.8%).
