Understanding Medulloblastoma: An Overview
Medulloblastoma is the most common pediatric brain tumor. It’s very important to catch it early. It happens mostly in the cerebellum, which helps with movement.
What is Medulloblastoma?
It’s a fast-growing tumor in kids. It’s a type of CNS tumor that can spread quickly. Getting help right after finding out is key.
Incidence and Risk Factors
Studies show medulloblastoma makes up about 20% of pediatric brain tumors. It’s a big deal for young people. Things that raise the risk include family genes and being exposed to radiation.
Medulloblastoma Subtypes
There are four main types of medulloblastoma, each with its own traits: KDM6A Medulloblastoma: Genetic Insights & Therapy
- WNT (Wingless) subtype: This is the best type to have, with a good chance of getting better.
- SHH (Sonic Hedgehog) subtype: This type is seen in kids of all ages and has special features.
- Group 3: This is the worst type, often with bad outcomes.
- Group 4: This is the most common type, with a middle chance of getting better.
Knowing these types helps doctors make better plans for pediatric brain tumor patients.
The Role of Genetics in Medulloblastoma
Medulloblastoma is a type of brain tumor with lots of genetic differences. Cancer Genomics has changed how we see this cancer. It shows us how genes that help cancer grow and genes that stop it are important.
Genetic Mutations and Pathways
Studies, like those from The Cancer Genome Atlas (TCGA), have found key genetic changes in medulloblastoma. The sonic hedgehog pathway is a big deal in these findings. It’s a way that cells talk to each other, and when it’s broken, it helps tumors grow. Changes in oncogenes and tumor suppressor genes in this pathway are big clues.
