About

This is a research study using Granulocyte Colony Stimulating Factor (GCSF) as a bone marrow stimulating agent for imaging to guide radiation treatment planning. G-CSF is a type of growth factor. Growth factors are proteins made in the body. G-CSF is a type of growth factor that makes the bone marrow produce white blood cells to reduce the risk of infection after some types of cancer treatment. GCSF is being given to stimulate the bone marrow to identify the active (blood cell producing regions) to better spare during pelvic radiation treatment planning.

Full description

This is a phase 1/2 study. The phase 1 is a dose finding portion of the study and phase 2 will enroll additional patients at the dose found in phase I. Patients in phase I and phase 2 will have the same treatment and follow-up.

Participants will undergo standard of care diagnostic imaging, complete blood count (CBC) with differential and chemistry labs initially. While receiving the GCSF, participants will have a CBC with differential checked a day after each dose and one day prior to first day of radiation. The treatment planning FDG PET/CT will be performed shortly after the GCSF. During chemoradiation, participants will have weekly CBC with differential checked and other labs as standard of care.
