Diagnosis and Staging
The process of medulloblastoma diagnosis is thorough. It uses many steps to make sure the disease is correctly identified and staged. Important tools include MRI and CT scans. These scans show detailed pictures of the brain and spinal cord.
An MRI scan is often the first choice because it gives clear images. It helps see normal and abnormal brain parts. CT scans are used when quick images are needed, like in emergencies.
After imaging, a lumbar puncture might be done. This is to check the cerebrospinal fluid (CSF) for tumor cells. It helps see if the tumor has spread to the spinal cord.
Medulloblastoma Treatment Strategies Explored Sometimes, a biopsy is needed to confirm the diagnosis. A biopsy takes a tumor sample for a closer look under a microscope. This tells doctors the type and grade of the tumor.
After confirming medulloblastoma diagnosis, the next step is cancer staging. This tells doctors how far the disease has spread. The TNM system is often used, which looks at:
- T (Tumor): The size and spread of the main tumor
- N (Nodes): If cancer has spread to nearby lymph nodes
- M (Metastasis): If cancer has spread to other parts of the body
Other systems might be used too, based on medical guidelines. This detailed staging helps doctors plan the best treatment for each patient. It makes treatment more effective.
| Staging Criteria | Description |
|---|---|
| T (Tumor) | Looks at the size and spread of the main tumor. |
| N (Nodes) | Checks if cancer has spread to nearby lymph nodes. |
| M (Metastasis) | Sees if cancer has spread to distant parts of the body. |
Surgical Treatment Options for Medulloblastoma
Surgery is key in treating medulloblastoma. It aims to remove the tumor and save brain function. Before surgery, doctors plan carefully to get the best results.
Pre-Surgery Evaluation
Before surgery, a detailed check-up is done. This includes MRI and CT scans to see the tumor’s size and where it is. Doctors from different fields work together to plan the surgery well.
They look at the patient’s health to make sure they’re ready for surgery. This helps lower the risk of problems during the procedure.
Surgical Techniques and Approaches
Many surgical methods are used for medulloblastoma. Each method depends on the tumor and the patient. Here are some:
- Microsurgery: Uses high-precision microscopes for better visibility and accuracy.
