How is stem cell collection done for myeloma treatment?
Stem cell collection, also called apheresis, is a key step before a stem cell transplant. Here's what happens:
Preparation Phase:
Before collection begins, you'll receive daily injections of growth factors for about a week. These medications encourage stem cells to move from your bone marrow into your bloodstream, increasing the number of stem cells available for collection.
The Collection Process:
A catheter or port is placed in your chest or arm if you don't already have one. During apheresis, a machine draws blood from one port, separates and collects the stem cells, then returns the rest of your blood through another port.
The collection typically takes three to four hours per session and often needs to be repeated for up to five days, depending on how many cells are collected. Everyone's different - some people need just a couple of days while others need more.
After Collection:
Once enough stem cells are gathered and cleaned, they're placed in an IV bag and frozen until you're ready for your transplant.
The process is generally well-tolerated, though you may feel tired afterward. Your healthcare team will monitor you throughout to ensure everything goes smoothly.
