Chronic Myeloid Leukemia (CML): Surgery
In rare cases, chronic myeloid leukemia (CML) may be treated with surgery to remove a swollen spleen. This is called a splenectomy. The goal is not to cure CML, but to improve symptoms so you feel better.
What is the spleen?
The spleen is an organ near the stomach. It’s part of the system that makes white blood cells and destroys old red blood cells. It also helps to prevent infections by filtering bacteria in the blood.
When splenectomy is done for CML
A splenectomy may help improve blood counts and relieve pressure and mild pain from an enlarged spleen that's pressing on nearby tissues and organs. A splenectomy might be advised if:
-
Your spleen is so swollen that it's pushing on other organs, such as your stomach. Other treatments, such as chemotherapy or radiation therapy, are often used first to try to shrink the spleen.
-
Your spleen is filtering out too many red blood cells and platelets from your blood. It's your spleen's job to remove worn-out blood cells. But leukemia can make your spleen overactive. A splenectomy can help raise your red blood cell and platelet counts.
Vaccines before your surgery
You may need some vaccines before surgery to remove your spleen. This is because your risk for certain infections will go up after your spleen is removed.
What to expect for your surgery
A splenectomy is done in a hospital. The surgery takes up to a few hours. It depends on the way the surgery is done. Splenectomy can be done by making 1 large cut (incision) or a few smaller incisions in your belly (abdomen). The main artery going to your spleen is tied off. The spleen is removed. Your incision is then closed with stitches (sutures). Talk with your healthcare provider about whether or not you will need to stay in the hospital after surgery.
Preventing infections after a splenectomy
You'll need to be careful to prevent infection after your surgery and for the rest of your life. That's because your spleen helps protect you against some types of infection. Your healthcare provider will likely encourage you to get vaccines to help prevent certain infections. You'll get more information on this.
