What Is a Haploidentical (Half-Match) Bone Marrow Transplant?
A haploidentical bone marrow transplant is a type of allogeneic hematopoietic stem cell transplant in which the donor shares 50% of the recipient’s HLA (human leukocyte antigen) markers. This makes it possible for patients to undergo a transplant using a partially matched family member when a fully matched sibling or unrelated donor is unavailable.
Key Points:
- Donor is usually a parent, child, or half-matched sibling
- Increases chances of finding a donor within family
- Uses advanced immunosuppressive protocols to prevent rejection and graft-versus-host disease (GVHD)
This method has greatly expanded access to transplants for patients worldwide, especially those from ethnic minorities or underrepresented donor groups.
How Does a Haploidentical Transplant Work and Who Is Eligible?
In a haploidentical BMT, donor stem cells are collected and infused into the patient after intensive conditioning (chemotherapy/radiation). Modern techniques ensure the patient’s immune system accepts these half-matched cells.
Eligibility Criteria:
- No fully matched donor available (sibling/unrelated)
- Diagnosed with leukemia, lymphoma, aplastic anemia, or other serious blood disorders
- Patient is fit for myeloablative or reduced-intensity conditioning
- Availability of a biological parent or child as donor
Who is not eligible?
- Patients with multi-organ failure
- Active uncontrolled infections
- Severe cardiac or pulmonary impairment
Indian transplant teams conduct rigorous pre-BMT evaluations to ensure safety and suitability.

Haploidentical BMT removes donor search delays and expands transplant options, especially for patients without sibling matches.
Which Diseases Are Treated with Haploidentical BMT in India?
India’s advanced transplant centers successfully use haploidentical BMT to treat a wide range of malignant and non-malignant hematological diseases.
Malignant Disorders:
- Acute lymphoblastic leukemia (ALL)
- Acute myeloid leukemia (AML)
- Chronic myeloid leukemia (CML)
- Hodgkin and Non-Hodgkin lymphoma
- Myelodysplastic syndromes (MDS)
Non-Malignant Disorders:
- Severe aplastic anemia
- Thalassemia major
- Sickle cell disease
- Congenital immunodeficiency disorders (SCID, Wiskott-Aldrich Syndrome)
Pediatric Indications:
- Neuroblastoma
- Metabolic disorders
India’s BMT protocols follow international standards from EBMT, ASBMT, and NMDP, ensuring safety and excellent outcomes across age groups.
What Is the Step-by-Step Treatment Protocol for Haploidentical Bone Marrow Transplant in India?
The haploidentical transplant process in India follows a systematic and multidisciplinary approach to ensure optimal outcomes.
1. Donor Evaluation & Matching:
- HLA typing to determine 50% match
- Basic health check, viral testing, blood compatibility
- Infectious disease clearance
2. Patient Pre-Transplant Evaluation:
- Complete blood count, kidney/liver function, echocardiogram
- Pulmonary function test (PFT)
- Bone marrow biopsy
- Chest X-ray, CT scans
- Viral screening (CMV, Hep B/C, HIV)
3. Conditioning Regimen:
- High-dose chemotherapy or radiation
- Goal: destroy cancer cells and suppress immunity
- Common regimens: Fludarabine, Busulfan, Cyclophosphamide
4. Stem Cell Collection (Donor):
- G-CSF administered for 4–5 days to mobilize stem cells
- Peripheral blood stem cells collected via apheresis
- Sometimes, bone marrow is harvested under general anesthesia
5. Stem Cell Transplantation:
- Cells infused via central venous catheter
- Done like a blood transfusion, over 2–4 hours
6. Post-Transplant Monitoring:
- Isolation in sterile HEPA-filtered BMT rooms
- Daily blood tests, fever watch, supportive care
- Neutrophil engraftment in 12–20 days
- Medications to prevent GVHD, infections, and rejection
India uses post-transplant cyclophosphamide (PTCy) to reduce GVHD risk in haploidentical transplants, a globally accepted protocol.
What Devices, Technology, and Safety Systems Are Used in Indian BMT Units?
India’s top BMT hospitals are equipped with international-grade infrastructure and the latest technology to ensure safe and successful haploidentical bone marrow transplants.
Advanced Diagnostic Tools:
- Flow cytometry for leukemia typing and MRD (Minimal Residual Disease)
- HLA typing and PCR-based tests for genetic compatibility
- Viral screening with ELISA, PCR, and CMV load testing
Stem Cell Collection & Processing:
- Apheresis machines: Spectra Optia, Fresenius COM.TEC
- Stem cell cryopreservation in liquid nitrogen tanks at –196°C
- Controlled-rate freezers to prevent cell damage
BMT Units and Isolation Rooms:
- Positive pressure isolation rooms with HEPA filters
- Separate air-handling units to minimize infection risk
- 24x7 monitoring of vitals with bedside patient monitors
Infection Control & Supportive Care:
- High-end pharmacy with antifungals, antivirals, and immunosuppressants
- Sterile units for chemo administration
- Automated blood counters and culture machines
These technologies help ensure engraftment success, manage complications, and reduce infection risk.
