Is this trial a fit for you?

What this trial studies

This observational study aims to assess the outcomes for mothers diagnosed with cancer during pregnancy and the long-term effects on their children who were exposed to cancer treatments such as chemotherapy and radiotherapy. It includes collecting maternal blood samples, umbilical cord blood, and biopsies to evaluate fetal growth and maternal health. Additionally, the study will measure maternal and paternal anxiety related to the cancer diagnosis and conduct long-term follow-ups on the children to monitor their neurological and cardiological development. The study is structured in two parts, focusing on both maternal outcomes and child development.

Why it matters

Potential benefit: If successful, this study could provide critical insights into the safety and outcomes of cancer treatments during pregnancy, potentially guiding future clinical practices.

How similar studies have gone: While there have been studies on cancer treatment during pregnancy, this specific approach focusing on long-term outcomes for both mothers and children is relatively novel.
