The Sriram Chandra Bhanja Medical College and Hospital (SCBMCH) in Cuttack successfully performed a haploidentical bone marrow transplant on a patient. It is said to be the first-ever such surgery in Odisha.
The surgery was performed on Subhrashu Sahu (29) from Kantabani village under Khordha’s Baghamari police limits. The donor was his 15-year-old younger brother.
As per reports, the health condition of both the patient and stem-donor is stable.
Subhrashu was diagnosed with blood cancer in 2016. Though he recovered in 2019, the disease relapsed later. The doctors this time decided to transplant his bone marrow with a suitable donor.
While the bone marrow transplant is usually done from a donor with a 100 percent or 90 percent match, the doctors opted for a haploidentical transplant after failing to find a close match.
A haploidentical transplant is a type of allogeneic transplant. It uses healthy, blood-forming cells from a half-matched donor to replace the unhealthy ones. The donor is typically a family member.
A haploidentical or half-matched donor is usually the mother, father or the child. Parents are always a half-match for their children. Siblings (brothers or sisters) have a 50% chance of being a half-match for each other. It’s very unlikely that other family members (like cousins, aunts or uncles) would be a half-match.
