Bone Marrow Transplantation is a specialized treatment for cancers like leukemia, lymphomas and some non-cancerous diseases like thalassemia. In a haploidentical transplant, the donor cells with only 50% match are used. This is in sharp contrast to transplant of perfectly matched cells. The donor can be a family member that includes parents, children and siblings. Haploidentical Bone Marrow Transplant is advised only during certain conditions, when there is no fully human leukocyte antigen (HLA) matched family donor or matched unrelated donor.
Highest quality irradiation procedures are facilitated by innovative technologies. The entire bone marrow is targeted with higher doses of radiation, without exposing other organs to its harmful effects.
Importantly, the condition of sick patients with zero white blood counts is crucial, as they are at greater risk of life. These patients are placed in the special BMT unit which has a stand by ventilators, dialysis machine, ultrasound and X-ray machine.

The four stages of the BMT process includes,
Each patient needs to undergo a complete medical check-up to evaluate his/her suitability for the bone marrow transplant process. The medical check-up includes blood tests, chest X-ray and CT Scan, heart and lung condition, and bone marrow check. Patients are counselled about the BMT procedure, complications and chances of success.
The patient is given high dose of chemotherapy or radiotherapy to destroy the diseased marrow. The stem cells or bone marrow cells are given to the patient through the Central Venous Line (CVL). Possible complications that may occur due to bone marrow transplant like allergic reactions, high blood pressure and high heart rate are effectively treated. Immunosuppressants are given to suppress the immune system and reduce the risk of rejection of new stem cells or bone marrow.
The patient is kept in the clean room of the BMT facility. Blood and platelet transfusions are given and the infections are treated with antibiotics.
In the first three months following bone marrow transplant, the white blood cells (neutrophils and lymphocytes) count is ensured to be above the critical value, before the patient is moved out of critical isolation. This condition shows that the transplanted blood cells are working normally. Significantly, if the neutrophils increase to normal or near-normal levels, the patient is ready for discharge. In the next twelve months, as the risk of graft-versus-host disease (GVHD) is very high, the patient has to undergo regular check-ups and blood test (2-3 times a week) to check the WBC count as there is still the risk of infections from viruses and fungus.
