<h1>Woman with relapsed blood cancer receives successful bone marrow transplant using advanced TMLI radiation therapy</h1> A Chennai hospital successfully performed a bone marrow transplant on a 29-year-old woman with relapsed blood cancer using Total Marrow and Lymphoid Irradiation (TMLI), a specialized radiation therapy. The patient received stem cells from her sister as a matched donor. TMLI precisely targets bone marrow and lymphoid tissues while sparing vital organs, reducing complications compared to total body radiation. The treatment combined immunotherapy, precision radiation, and transplant procedures. The patient showed early signs of successful engraftment with complete chimerism, indicating 100% donor-derived cells in analyzed samples.
