Trial status:

Open for Enrollment

Why is this study being done?

OBJECTIVES: Primary - Classify patients with renal tumors by histological categorization, surgico-pathological stage, presence of metastases, age at diagnosis, tumor weight, and loss of heterozygosity for chromosomes 1p and 16q, to define eligibility for a series of therapeutic studies. - Maintain a biological samples bank to make specimens available to scientists to evaluate additional potential biological prognostic variables and for the conduct of other research by scientists. Secondary - Monitor outcome for those patients who are not eligible for a subsequent therapeutic study. - Describe whether the pulmonary tumor burden correlates with outcome in patients with stage IV disease. - Describe the sensitivity and specificity of abdominal CT scan by comparing it with surgical and pathologic findings for identification of local tumor spread beyond the renal capsule to adjacent muscle and organs, lymph node involvement at the renal hilum and in the retroperitoneum, preoperative tumor rupture, and metastases to the liver. - Compare the sensitivity and specificity of pre-operative abdominal CT scan and MRI for the identification and differentiation of nephrogenic rests and Wilms' tumor in children with multiple renal lesions. - Correlate the method of conception (natural vs assisted reproductive technology) with the development of Wilms' tumor. OUTLINE: This is a multicenter study. Tumor tissue, blood, and urine samples are collected for research studies, including immunohistochemistry. CT scans and MRIs are also performed. Loss of heterozygosity analyses (chromosome 1p and 16q) are performed by extraction of DNA. DNA polymorphisms are assayed by polymerase chain reaction using standard methodology. Leftover specimens are archived for future studies. Patients are followed periodically for 5 years. PROJECTED ACCRUAL: There are no sample size goals for this study.
