Study Notes
Stem Cell Therapy for Leukemia: Autologous vs. Allogeneic
- Leukemia treatment involves stem cell transplantation, either autologous or allogeneic.
- Autologous transplantation uses the patient's own stem cells
- Allogeneic transplantation uses stem cells from a matched donor.
Autologous Stem Cell Transplantation
-
Mechanism of Action:
- Complete remission after cancer treatment is achieved.
- The body regenerates blood-producing cells.
- It does not involve problems with graft-versus-host disease (GVHD)
-
Steps:
- Blood-forming stem cells are removed from the patient.
- Patient receives treatment to eliminate remaining cancer cells, and to ready their body for the donor stem cells.
- The patient receives back their stem cells.
Allogeneic Stem Cell Transplantation
-
Mechanism of Action:
- Destroys cancer cells and suppresses the patients' immune system.
- The graft-versus-tumor (GVT) effect is used to eliminate cancerous cells.
- The blood-producing system is regenerated.
-
Steps:
- Stem cells are collected from donor cells
- Stem cells are processed through a machine.
- Stem cells are infused into the patient.
- Patient receives treatment to reduce their immune system's strength to prevent rejection of donated stem cells.
Comparison of Transplant Types
| Aspect | Autologous Stem Cell Transplantation | Allogeneic Stem Cell Transplantation |
|---|---|---|
| Source of Stem Cells | Patient's own stem cells | Stem cells from a matched donor (sibling or unrelated) |
| Risk of GVHD | No risk | Higher risk |
| Immuno-suppression | Not required | Required |
| Risk of Infections | Lower | Higher |
| GVT effect | No | Yes |
| Relapse risk | Higher | Lower |
| Eligibility | Depends on complete remission before transplant | Depends on a compatible donor health |
| Complications | Lower, but relapse can be a major concern | Higher, due to GVHD and infections |
| Suitable patients | Older patients or those with health concerns; Low risk leukemia/ remission risk | Younger, healthier individuals; High risk or relapsed leukemia. |
