Stem Cell Transplant Treatment and Procedures

The Transplant Timeline: A Phased Approach

Undergoing a stem cell transplant is often described by survivors not merely as a medical treatment, but as a journey of rebirth. It is a sophisticated, multi-stage process that requires precision, patience, and world-class medical expertise. At Liv Hospital, we guide our international patients through every step of this journey, transforming a complex biological procedure into a structured, manageable, and supported experience.

For many patients traveling from the US and Europe, the primary concern is understanding exactly what happens during the weeks spent in the hospital. Unlike a standard surgery where you are asleep and wake up “fixed,” a stem cell transplant is an active process. It involves harnessing the power of your own body (or a donor’s) to rebuild an entire immune system from scratch.

Our Hematology and Bone Marrow Transplant Unit is designed specifically for this purpose. From the advanced apheresis machines used to collect cells to the HEPA-filtered isolation rooms that protect you during recovery, every detail is engineered for safety and success.

Step 1: Mobilization and Harvesting – Collecting the Life-Saving Cells

The journey begins long before the actual transplant day. The first critical phase is “harvesting” or collecting the stem cells that will later save the patient’s life.

For Autologous Patients (Self-Donor): The process starts with Mobilization. Under normal conditions, stem cells live deep inside the bone marrow and do not circulate in the blood. To get them out, we administer daily injections of a growth factor called G-CSF (Granulocyte-Colony Stimulating Factor) for 4 to 5 days. This medication stimulates the bone marrow to produce millions of stem cells and release them into the bloodstream.

Once the stem cell count in the blood is high enough, Apheresis begins.

  • The Procedure: The patient is connected to a cell separator machine (Spectra Optia®) via a catheter in the arm or neck.
  • The Experience: It feels similar to donating blood platelets. Blood is drawn, spun in the machine to separate the stem cells, and the remaining blood is returned to the body.
  • Duration: This painless process typically takes 3 to 4 hours. The collected cells are then frozen (cryopreserved) and stored until needed.

For Allogeneic Patients (Donor): The donor undergoes the same mobilization and apheresis process. In rare cases (such as for certain pediatric conditions or aplastic anemia), we may need to harvest cells directly from the pelvic bone under anesthesia. However, 90% of transplants at Liv Hospital use the non-surgical peripheral blood method described above.

Step 2: The Conditioning Regimen – Preparing the Body

Phase 1: Mobilization and Harvesting

Once the cells are safely stored or the donor is ready, the patient is admitted to the transplant unit to begin the Conditioning Phase. This is often considered the most physically demanding part of the treatment.

The Purpose of Conditioning:

  1. Eradicate Disease: High doses of chemotherapy (and sometimes Total Body Irradiation – TBI) are delivered to kill any remaining cancer cells in the body.
  2. Suppress Immunity: For allogeneic transplants, the patient’s immune system must be temporarily suppressed so it does not attack the new donor cells.
  3. Create Space: The chemotherapy clears out the old bone marrow, creating physical “room” for the new stem cells to settle and grow.

Managing Side Effects: At Liv Hospital, we use a “supportive care first” approach. We know that conditioning can cause nausea, mucositis (mouth sores), and fatigue. Therefore, we do not wait for symptoms to appear. We administer anti-nausea medications, antiviral prophylaxis, and specialized oral care protocols preventatively. Our clinical nutritionists also adjust the patient’s diet to ensure they maintain strength when eating becomes difficult.

Step 3: Day Zero – The Transplant Infusion

Graft-versus-Host Disease (GVHD) Prophylaxis

After the conditioning is complete, there is usually a rest day, followed by Day 0. This is the day the transplant actually happens. For patients and our medical team alike, this is a day of celebration for a second birthday.

The Infusion Process: Contrary to popular belief, the transplant is not a surgery. It takes place right in the patient’s hospital room.

  • The Setup: The frozen cells (for autologous) are thawed at the bedside in a water bath, or fresh donor cells (for allogeneic) arrive from the lab.
  • The Administration: The cells are infused through the central venous catheter, looking very much like a bag of blood or plasma.
  • The Sensation: The process is painless. Patients are awake and can talk to their families. Some patients report a taste of “creamed corn” or garlic in their mouth during the infusion due to the preservative used in frozen cells, but this passes quickly.

The entire infusion can take anywhere from 30 minutes to a few hours, depending on the volume of cells. Once the bag is empty, the “transplant” is technically done, but the biological work is just beginning.

Step 4: The Engraftment Phase – The Waiting Game

After Day 0, the patient enters the Neutropenic Phase. This is the period where the old bone marrow has been destroyed, but the new cells haven’t started working yet. The immune system is effectively at zero.

Life in Isolation: To protect the patient during this vulnerable window, Liv Hospital utilizes specialized HEPA-filtered isolation rooms. These rooms maintain positive air pressure, ensuring that no outside air (and airborne bacteria) can enter when the door is opened.

  • Daily Routine: Patients are monitored 24/7. Blood tests are taken every morning to check cell counts.
  • Hygiene: Meticulous personal hygiene is enforced to prevent infection from the patient’s own skin bacteria.
  • Diet: A strict “neutropenic diet” is served—all food is thoroughly cooked, and no raw fruits or vegetables are allowed to eliminate the risk of foodborne bacteria.

The Sign of Success: Usually, between Day +10 and Day +21, a miracle happens. The white blood cell count, which has been at zero, starts to rise. This is called Engraftment. It means the stem cells have successfully migrated to the bone marrow “factory” and have started the production line. The patient often feels a sudden surge in energy and well-being as their body begins to defend itself again.

Advanced Techniques: Haploidentical and Mismatched Transplants

stem cell transplant

One of the reasons international patients choose Liv Hospital is our ability to perform complex transplants when a perfect donor is not available.

Standard transplants require a 10/10 HLA match. However, using Haploidentical Transplant protocols, we can use a donor who is only a half-match (like a parent, child, or sibling).

  • T-Cell Depletion Technology: We use sophisticated lab techniques to remove the specific immune cells (T-cells) from the donor graft that cause rejection, while keeping the stem cells and “fighter” cells that attack cancer.
  • Post-Transplant Cyclophosphamide: A specialized drug protocol that “re-educates” the immune system to accept the half-matched cells.

This capability means that virtually every patient has a potential donor, removing the biggest barrier to life-saving treatment.

Supportive Care: Treating the Whole Person

A stem cell transplant is as much a psychological challenge as it is a physical one. Isolation can be lonely, and the fear of the unknown is real.

  • Psychological Support: Our on-staff psychologists visit patients regularly to provide coping strategies and emotional support.
  • Physical Therapy: Staying in bed for weeks causes muscle loss. Our physiotherapists guide patients through gentle, in-room exercises (like stationary cycling) to maintain muscle mass and lung function, which has been proven to speed up engraftment.
  • Patient Concierge: For our US patients, our international team handles everything from visa extensions for family members to ordering favorite meals, ensuring the patient feels at home while far away.

FREQUENTLY ASKED QUESTIONS

Is the transplant procedure painful?

The transplant infusion itself is completely painless. The “harvesting” of stem cells from the blood is also painless, though holding your arm still for 3-4 hours can be tiring. The main discomfort comes from the side effects of chemotherapy (mouth sores, nausea), which are managed with medication.

Yes. We encourage patients to bring laptops, tablets, books, and photos to make the room feel like home. However, all items must be wiped down and sterilized by our nursing staff before being brought into the clean zone.

Hair loss typically begins 2-3 weeks after conditioning chemotherapy starts. Regrowth usually begins within 3 to 6 months after the transplant. Interestingly, the new hair may come back with a different texture or color (sometimes called “chemo curls”).

If the new cells fail to engraft (which is rare) or the disease returns, a second “salvage” transplant can be considered. Liv Hospital also offers “Donor Lymphocyte Infusions” (DLI) a booster shot of donor immune cells to help kickstart the graft or fight relapse.

Yes, but with strict protocols. Usually, one designated family member can visit or stay in the room (depending on the specific unit rules), provided they are healthy and wear protective clothing (masks, gowns) supplied by the hospital.
