Retinoblastoma Patient Clinical Database and Tissue Repository (NCT04959097)

🟢 Recruiting Interventional Protocol 📊 Observational Clinical Research Sponsor: Children's Hospital Los Angeles

🩺 Plain-English Summary (8th-Grade Level)

Retinoblastoma (RB) is a primary eye cancer that forms in the back of the eye of infants and toddlers. Traditionally, RB is diagnosed without a biopsy; tumor can only be studied once an eye has been surgically removed. Given this limitation, we use aqueous humor (AH), the clear fluid in the front of the eye to detect specific markers, or information, that comes from the tumor itself.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (1 items) and avoid the listed exclusions (2 items).
