Study summary

This study is being done to investigate clonal hematopoiesis and therapy-emergent myeloid neoplasms in patients with ovarian or other solid cancers. Researchers want to identify risk factors for developing these blood cancers as well as if there is/are a genetic/environmental component(s) to developing blood cancer.

Read the detailed description

OUTLINE: This is an observational study.

Patients undergo blood sample collection and complete surveys on study. Patients' medical records are also reviewed.

What researchers measure

Primary outcomes

  1. Determine the correlation between baseline TP53m VAF in blood with CH expansion in OC patients

    Time frame: Through study completion, up to 5 years

  2. Identify risk of TMN for OC survivors with and without TP53m CH treated with platinum chemotherapy and PARP inhibitors

    Measurement Tool: will measure by BM biopsy confirmation done by local hematologist

    Time frame: Through study completion, up to 5 years

  3. Define the trajectories of clonal evolution and mechanisms of transformation from non-cancerous TP53m to TMN

    Measurement Tool: the variant allele fraction of the blood clone

    Time frame: Through study completion, up to 5 years
