Summary
Brief summary (as posted)
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.

[]Primary outcomes (2)
- measure
- Correlation of Ocular Salvage (eye saved) with biomarkers
- timeFrame
- through study completion, a minimum of 12 months after diagnosis and average of 24 months
- description
- We aim to evaluate whether any identifiable molecular biomarkers (e.g. chromosomal alterations or tumor fraction) in the aqueous or blood can predict ocular salvage, or the likelihood of saving the eye with therapy
- measure
- Identification of RB1 (RB Transcriptional Corepressor 1) gene mutations from the AH liquid biopsy
- timeFrame
- through study completion, a minimum of 12 months after diagnosis and average of 24 months
- description
- We aim to identify both somatic and germline RB1 gene mutations in the AH
Secondary outcomes (2)
- measure
- Correlation of High-Risk Histopathologic Features with presence of biomarkers
- timeFrame
- through study completion, a minimum of 12 months after diagnosis and average of 24 months (only if the eye is enucleated)
