He's Getting a What?

This central line is working. The plan is to start the conditioning chemo tomorrow.

In 8 days, Jenson gets an allogeneic, nonmyeloablative bone marrow transplant from Sydney's stem cells.

For those of you without medical degrees, here is an explanation I found on the web:


Bone marrow transplant
A bone marrow transplant is a procedure to replace damaged or destroyed bone marrow with healthy bone marrow stem cells.

Bone marrow is the soft, fatty tissue inside your bones. Stem cells are immature cells in the bone marrow that give rise to all of your blood cells.

Description
There are three kinds of bone marrow transplants:

Autologous bone marrow transplant: "Auto" means "self." Stem cells are removed from you before you receive high-dose chemotherapy or radiation treatment. After these treatments are done, your stems cells are put back in your body. This is called a "rescue" transplant.

Allogeneic bone marrow transplant: "Allo" means "other." Stem cells are removed from another person, called a donor. Most times, the donor must have the same genetic makeup as the patient, so that their blood is a "match" to yours. Special blood tests are done to determine if a donor is a good match for you. A brother or sister is most likely to be a good match. Donors who are not related to the patient may be found through national bone marrow registries.

Umbilical cord blood transplant: Stem cells are removed from a newborn baby's umbilical cord immediately after being born. The stem cells are stored until they are needed for a transplant. Umbilical cord blood cells are so immature, there is less of a concern that they will not match.

Before the transplant, chemotherapy, radiation, or both may be given. This may be done in two ways:

Ablative (myeloablative) treatment: High-dose chemotherapy, radiation, or both are given to kill any cancer cells. This allows new stem cells to grow in the bone marrow.

Reduced intensity (nonmyeloablative) treatment: Today, some patients are getting lower doses of chemotherapy and radiation before a bone marrow transplant.

A stem cell transplant is done after chemotherapy and radiation is complete. The stem cells are delivered into your bloodstream through a tube called a central venous catheter. The process is similar to getting a blood transfusion. The stem cells travel through the blood into the bone marrow. Usually, no surgery is required.

Minor surgery may be needed to collect bone marrow and stem cells from a donor. This is called a bone marrow harvest. The surgery is done under general anesthesia, which means the donor will be asleep and pain-free during the procedure. The bone marrow is removed from the hip bones.

Why the Procedure is Performed
A bone marrow transplant replaces bone marrow that is either not working properly or has been destroyed (ablated) by chemotherapy or radiation.

Your doctor may recommend a bone marrow transplant if you have:

Certain cancers, such as leukemia, lymphoma, and multiple myeloma
A disease that affects the production of bone marrow cells, such as:
Sickle cell anemia
Aplastic anemia
Thalassemia
Congenital neutropenia
Severe immunodeficiency syndromes
Had chemotherapy that destroyed your bone marrow

Risks
A bone marrow transplant may cause the following symptoms:

Pain
Chills
Fever
Hives
Chest pain
Drop in blood pressure
Shortness of breath
Nausea
Flushing
Headache
Funny taste in the mouth

Possible complications of a bone marrow transplant depend on many things, including:

The disease you are being treated for
If you had chemotherapy or radiation before the bone marrow transplant
Your age
Your overall health
How good of a match your donor was
The type of bone marrow transplant you received (autologous, allogeneic, or umbilical cord blood)

Complications can include:

Infections, which can be very serious
Bleeding in the lungs, the intestines, brain, and other areas of the body
Anemia
Stomach problems, including diarrhea, nausea, and vomiting
Pain
Inflammation and soreness in the mouth, throat, esophagus, and stomach, called mucositis
Damage to the kidneys, liver, lungs, and heart
Cataracts
Early menopause
Graft failure, which means that the new cells do not settle into the body and start producing stem cells
Graft-versus-host disease , a condition in which the donor cells attack your own body
Delayed growth in children who receive a bone marrow transplant

Before the Procedure
Your health care provider will ask you about your medical history and do a physical exam. You will have many tests before your treatment begins.

Your doctor or nurse should discuss the emotional stress of having a bone marrow transplant. You may want to meet with a mental health counselor. It is important to talk to your family and children to help them understand what to expect.

You will need to make plans to help you prepare for the procedure and handle tasks after your transplant. Things to consider include:

Advanced care directives
Arranging medical leave from work
Bank or financial statements
Care of pets
Household chores
Insurance coverage
Payment of bills
Schedules and care for your children
You may need to find housing for yourself or your family near the hospital.

After the Procedure
A bone marrow transplant is usually done in a hospital or medical center that specializes in such treatment. Most of the time, you will stay in a special bone marrow transplant unit in the center to limit your chance of getting an infection.

How long you stay in the hospital depends on how much chemotherapy or radiation you received, the type of transplant, and your medical center's procedures. While you are in the hospital, you will be isolated because of the increased risk of infection. The health care team will closely monitor your blood count and vital signs.

While you are in the hospital you may:

Receive medications to prevent or treat infections, including antibiotics, antifungals, and antiviral drugs.
Need many blood transfusions
Be fed through a vein (IV) until you can eat by mouth and stomach side effects and mouth sores have gone away
Be given medication to prevent graft-versus-host disease

Outlook (Prognosis)
How well you do after transplant greatly depends on:

The type of bone marrow transplant
How well the donor’s cells matched yours
What type of cancer or illness you have
Your age and overall health
The type of chemotherapy or radiation therapy you had before your transplant
Any complications
Your genes

A bone marrow transplant may completely or partially cure your illness. If the transplant is a success, you can go back to most of your normal activities as soon as you feel well enough. Most times it takes up to 1 year to recover fully.

Complications or failure of the bone marrow transplant can lead to death.
