NCT ID: NCT02160795 Withdrawn - Pediatric Leukemia Clinical Trials

Feasibility of Identifying a Chinese Study Population and Eligible Pediatric Cancer Cases, and Linking the Two Groups to Assess the Role of Periconceptional Folic Acid Supplements in Risk of Pediatric Cancer.

Start date: March 27, 2014
Phase:
Study type: Observational

Background: - Pregnant women are encouraged to take the vitamin folate. It helps prevent some birth defects. Children of mothers who take it also have less risk of some cancers. Between 1993 and 1995, some women in China took the vitamin daily before and during early pregnancy. Another group did not. This study will follow up on children born to both sets of women. (The children were born between 1994 and 1996.) Researchers will use these data to study the link between folate and cancer in infants and children. Objective: - To see if folate may reduce childhood cancer if women take it every day before and during early pregnancy. Eligibility: - Mothers who took part in a Chinese folic acid study between 1993 and 1995 and their offspring. Design: - Mothers of children in the study will sign a consent form. The form lets the researchers review the child s medical history. They may also review data about their cancer diagnosis. The children will also sign a form.
