1, Methods The ultrasonic manifestations of 46 cases of nephroblastoma confirmed by surgery and pathology were studied retrospectively.

2, Objective To probe the clinical pathological features of nephroblastoma, which is also called Wilm′s Tumor(WT).

3, To date,(http:///nephroblastoma.html) the angiogenesis activity of nephroblastoma and its regulators have not been well defined.

4, Methods: 7 cases of adult nephroblastoma confirmed by surgery and pathology were analyzed retrospectively.

5, Objective To study the relationship of nephroblastoma to the differentiation and development of fetal kidney and to the existence of nephrogenic rest(NR).

6, Conclusions The results suggested that the genesis of nephroblastoma is relevant to the retarded differentiation of fetal kidney. NR is the precursor lesion of nephroblastoma.

7, Objective: To evaluate the value of CT in diagnosing and staging of nephroblastoma in children.

8, The survival rate of children suffering from highly differentiated nephroblastoma increased to 90. 48% by combined therapy by operation, chemotherapy and radiotherapy in 42 cases.

9, The most common origins are the orbit and the kidneys and the predominant tumors are retinoblastoma and nephroblastoma respectively. In contrast to those found in Shanghai and Shandong, the inciden...

10, Materials and Method:To analyse the CT manifestations on 36 cases of adrenal neuroblastoma and 32 cases of nephroblastoma both confirmed by postoperative pathologic diagnosis.

11, Conclusion: There is a lower expression of E cadherin in nephroblastoma.

12, The diagnostic model combined with 2 biomarkers could separate nephroblastoma from other child′s abdominal solid tumors with a sensitivity of 93.3%, and a specificity of 100%.

13, Methods: Immunohistochemical staining S P was used to detect E cadherin protein in 30 tissue samples of nephroblastoma and 11 tissue samples of the adjacent kidney.

14, For these years, residua of metanephric blastema and delay of differentiation in the development of kidney have been considered the cause of nephroblastoma.

15, To study the significance of microvessel count (MVC) in nephroblastoma.

16, Objective To investigate the particularity of therapy of bilateral nephroblastoma ( BWT ) and necessity of lifetime follow - up.

17, The DNA content and cell cycle in paraffin-embedded sections collected from 5 cases of congenital mesoblastic nephroma. 96 cases of nephroblastoma and 27 normal kidneys were studied by flow cytometry.

18, Objective To explore the new method to monitor the prognosis of nephroblastoma.
