Summary of

Choroid plexus papilloma

Choroid plexus tumors are primary central nervous system (CNS) tumors. This means they begin in the brain or spinal cord.

Choroid plexus papillomas are grouped in two grades based on their characteristics.

  1. Grade I choroid plexus papilloma are low grade tumors. This means the tumor cells grow slowly.
  2. Grade II atypical choroid plexus papilloma are mid-grade tumors. This means the tumors have a higher chance of coming back after being removed.

Choroid plexus tumors occur in both children and adults, but are more common in children in the first year of life. Choroid plexus tumors occur slightly more often in females than males.

Choroid Plexus Tumors was originally published by the National Cancer Institute.

You can request raw data by completing this form. The review normally takes 1 week. Once approved you can access the raw data by creating cohorts of interest on the Kids First Data Resource Portal and performing analysis on the cloud in Cavatica

Flash frozen tissue is tissue from a surgical procedure where the tissue is frozen instantly in liquid nitrogen to ensure there is no degradation

Tissue in freezing media is tissue from a surgical procedure where the tissue is frozen 1 degree at a time over a 24-hour period to keep the tissue intact and compatible with regrowing the tumor for testing

Matched blood is blood that is collected from the patient in addition to tissue from the tumor. This blood provides researchers a direct comparison between normal and tumor specimens for this specific patient

Cerebral Spinal Fluid (CFS) is fluid taken from the the nervous system that researchers can use to study brain tumors

Paternal and maternal specimens are specimens taken from the biological parents of the subject. These specimens provide researchers with the ability to compare tumor and normal tissue and predispositions
