Stem Cell Treatment

We are the first academic National Cancer Institute (NCI)-designated Cancer Center in South Texas to offer this advanced treatment. 

The Stem Cell Transplant and Cellular Therapy Program at Mays Cancer Center provides stem cell therapy to Hodgkin lymphoma and non-Hodgkin lymphoma, multiple myeloma and testicular cancer patients. 

What is stem cell therapy?

Stem cell therapy is also called stem cell treatment or transplant. It uses healthy stem cells to replace blood cells that are affected by chemotherapy treatment. While chemotherapy destroys cancer cells, it also destroys healthy cells. The stem cells used for transplant can come from the patient themselves or from a viable donor. 

Types of stem cell therapy

There are two main types of stem cell treatment, including:

• Allogeneic stem cell transplant (SCT): An SCT uses stem cells from a donor, who may be a relative or someone who is not related. Before the procedure, the patient receives a conditioning treatment to prevent their immune system from rejecting the donor cells. The conditioning treatment may include chemotherapy, radiation or both. The new cells flow through the patient’s bloodstream to the bone marrow. SCT is typically used for types of leukemia.
• Autologous stem cell transplant (ASCT): In an ASCT procedure, your own stem cells are collected (harvested) before high-dose chemotherapy treatment and saved (banked) for use later. After you have chemotherapy — and radiation, if you receive both treatments — the banked stem cells are returned to your body. Autologous transplant is typically used for Hodgkin lymphoma, non-Hodgkin lymphoma and myeloma. It can also be used for testicular cancer.

We currently perform only autologous stem cell transplant at Mays Cancer Center.

Stem cell treatment: What to expect

Autologous stem cell treatment involves several steps leading up to transplant:

Step 1: Referral and evaluation for stem cell therapy

You will need a referral from your hematologist to be considered for transplant. 

You will meet with a transplant doctor as an outpatient at Mays Cancer Center. Together, you will review your health history and discuss the procedure, its benefits and any potential risks. A coordinator will help verify your insurance coverage for the procedure.

Step 2: Pre-transplant work-up for stem cell therapy

Your pre-transplant work-up will include several tests to help determine whether you qualify for stem cell therapy. They include:

• Blood and urine tests
• Bone marrow assessment
• Dental exam (to find and treat any possible areas of infection, because your immune system will be weakened during stem cell treatment) 
• Heart and lung function tests
• Imaging such as a CT or PET scan
• Organ function test
• Psychosocial evaluation

Step 3: Preparing for stem cell treatment

After the test results come back, you will meet with your doctor to go over any questions, confirm your readiness and consent for the procedure.

A few days before your stem cell collection, you will start taking specific medications as a daily injection. The injections help your body produce more stem cells and move them from the bone marrow to your bloodstream. These medications can cause minor side effects such as aches and pains or flu symptoms.

Step 4: Stem cell collection

You will then return to Mays Cancer Center as an outpatient for stem cell collection. We take blood from a vein in your arm, like when you donate blood. It will then be processed through a machine that extracts the stem cells, which are then frozen and stored in the lab. This process is repeated daily for a period of one to five days.

Step 5: Conditioning regimen and treatment for stem cell therapy

You will then be admitted to UT Health San Antonio Multispecialty and Research Hospital. There you will be given high-dose chemotherapy treatment, along with radiation if it is part of your treatment plan. This may last over the course of about a week. The treatment destroys cancerous cells in preparation for transplant.

Step 6: Stem cell transplant and monitoring

Your transplant (engraftment) will be scheduled a day or two after your last chemotherapy and radiation dose. The frozen stem cells are thawed and then given to you through an infusion.   

The stem cells flow from your bloodstream into the bone marrow. They then begin producing new blood cells to replace those that the chemotherapy destroyed. Your stem cells will regrow, and blood counts will rise over a course of days to a couple weeks after your transplant. 

You will remain in the hospital for a few weeks to receive ongoing medical care. In some cases, you may need additional blood transfusions of platelets or red blood cells. During this time, you will be especially prone to infections. You may be given antibiotics to prevent or treat them.

Discharge and home recovery

After you are discharged and return home, you will have frequent outpatient follow-up appointments with your doctor. These last for the next four to six weeks. Your doctor will monitor you for complications and ensure your immune system is recovering. 

Recovery from autologous stem cell transplant can be slow. It may take a few or several months for you to begin feeling like your usual self.

Advanced Care Clinic

The Advanced Care Clinic (ACC) at the UT Health San Antonio Multispecialty and Research Hospital provides 24-hour specialty care. It’s designed for patients that have complications or side effects after a procedure, surgery or treatment. It is also for cancer patients. The ACC is staffed by doctors who provide expert diagnosis and care. It requires a referral from your oncologist or hematologist.

The ACC does not offer general emergency or urgent care services.

Learn more about the Advanced Care Clinic or call 210-450-1000 for a referral.

Survivorship services

Our Cancer Survivorship Program is available to support you well beyond the treatment phase. We focus on both the physical and emotional sides of cancer, promoting your ongoing wellness and quality of life.
