This may be news for India, but it happens quite often in the US. Autologous (from self) stem cell transplants are used to treat a variety of malignancies including lymphoma, leukemia, myeloma and others.
The stem cells are removed from the patient through a special separation process and stored. The cancer and remaining bone marrow are destroyed with high dose radiation and chemo, then the stem cells are reinfused.
They are referring to using it in patients with compromised kidneys. That’s what is new, as far as I can understand.
