Active clinical trials for "Wilms Tumor"

RATIONALE: Studying samples of blood, tissue, or bone marrow from patients with cancer in the laboratory may help doctors to learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research trial studies biomarkers in samples from younger patients with Wilms tumor.

Study purpose is to assess the prognostic role of Minimal Residual Disease (defined as medullary expression of WT1 gene), performed at Baseline and during treatment according to clinical practice. MRD results will be relate to treatment outcome and survival analysis variables (Overall Survival, Disease Free Survival, Cumulative Incidence of Relapse)

This study is a prospective, non-randomized observational study. Freshly isolated tumor cells will be tested for chemosensitivity to the standard of care drugs as single agents and in combinations using state-of-the-art viability assay designed for ex-vivo high-throughput drug sensitivity testing (DST). In addition, the genetic profile of the tumor will be obtained from the medical records and correlated with drug response.

RATIONALE: The identification of gene mutations in young patients with pleuropulmonary blastoma syndrome may allow doctors to better understand the genetic processes involved in the development of some types of cancer, and may also help doctors identify patients who are at risk for cancer. PURPOSE: This research study studies gene mutations in samples from young patients with pleuropulmonary blastoma syndrome at risk for developing cancer.

RATIONALE: Studying samples of urine from patients with cancer in the laboratory may help doctors identify biomarkers related to cancer. PURPOSE: This clinical trial studies biomarkers in urine from patients with Wilms tumor.

This laboratory study is evaluating how well dactinomycin and vincristine work in treating young patients with cancer. Studying samples of blood and urine in the laboratory from patients with cancer may help doctors learn how dactinomycin and vincristine affect the body and how patients will respond to treatment.

RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying biomarkers in blood and tumor tissue samples from patients with Wilms tumor.

RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This clinical trial studies biomarkers in tumor tissue samples from young patients with very low risk Wilms tumors.

Hepatic veno-occlusive diseases (VOD) during cancer treatment in children are serious toxicities that have occurred with interruptions of chemotherapy and risk of relapse. In addition, these toxicities have a negative impact on the patient's quality of life, serious long-term sequelae and are potentially fatal in children. The risk factors associated with the occurrence of these complications are, to date, unknown, at the exception to the exposition to certain treatments (6-thioguanine, busulfan, actinomycin D, radiotherapy, etc.). To understand the effects of this toxicity and those of susceptibility to the disease becomes a major issue in the treatment of these children.
