BACKGROUND/PURPOSE Despite high long-term survival rates in patients with Wilms tumor, there is a need to develop better prognostic biomarkers in order to maximize cure while avoiding treatment-associated morbidities. Tumor-associated macrophages have been recently associated with poorer prognosis and increased disease progression in a number of adult cancers. We investigated the relationship b...

Like testicular cancer in adulthood, the Wilms' tumor or nephroblastoma in childhood is an example of a curable malignant disease. The review by Huszno et al. in this Journal gives an overview concerning diagnosis and treatment of adult Wilms' tumors [1]. This tumor entity was first described in 1814 by Rance and in 1899 Max Wilms, a German surgeon, described this tumor in detail [2]. Beckwith ...

The diagnosis of extra-renal Wilms' tumor is often missed at initial clinical presentation leading to a delay in initiating appropriate therapy. A 5-year-old girl presented with a 3-week history of a painless lump in the pelvis. Radiological investigations suggested an ovarian neoplasm. Tumor markers for ovarian malignancy were in normal range. Trucut biopsy also suggested the possibility of an...

Nephroblastoma – also known as Wilms tumor – is the most frequent renal malignancy in childhood with the highest incidence of this tumor within the fourth year of life. 80% of patients are less than 5 years old, however it is a rare condition in neonates (<1%). In general, there are no known risk factors for the development of nephroblastoma, but it may be associated with rare conditions like D...

Low-grade endometrial stromal sarcoma (LGESS) with intravascular extension is very rare, with only 26 cases having been reported. We experienced a case of LGESS with inferior vena cava (IVC) extension. A 60-year-old female presented with left leg edema. She had a history of total hysterectomy, and was diagnosed of leiomyoma at that time. On imaging study, tumor masses were located around both c...

Mutations of the p53 tumor suppressor gene occur frequently in a variety of adult-onset tumors, including colon, breast, lung, and brain, yet are infrequently identified in pediatric malignancies. Wilms' tumor, a common solid tumor of childhood, can be associated with mutations of the WT1 gene. Alterations of the p53 gene have been shown to modulate the ability of WT1 to transactivate its targe...

BACKGROUND The most common renal tumors in adults is renal cell carcinoma. Wilms' tumor in subjects older than 16 years is rare; only 3% of Wilms' tumors are reported in adults, which explain the difficulties in diagnosis and treatment of this tumor entity in this age group. METHODS Patient with stage IV adult nephroblastoma with favorable histology was described, current treatment modalities...

The Wilms' tumor suppressor gene, WT1, encodes a zinc finger transcription factor that has been demonstrated to negatively regulate several growth factor and cognate receptor genes. However, inconsistent with its tumor suppressor function, WT1 has also been demonstrated to be required to inhibit programmed cell death in vitro and in vivo. Moreover, anaplastic Wilms' tumors, which typically expr...

We report a 13-month-old girl with primary intrarenal neuroblastoma initially diagnosed as Wilms' tumor. Intrarenal neuroblastoma is exceedingly rare in pediatric age that may masquerade as Wilms' tumor clinically and radiographically and it is important to differentiate for management.

Objective(s): To validate certain markers for cancer stem cell populations and their clinical importance in Wilms tumor (WT)Materials and Methods: Immunohistochemical study for CD133 and CD56/NCAM was performed on forty-six cases of WT that were diagnosed between 1999 and 2015, and the association of these markers with survival and progn...
