Autologous stem cell transplantation can treat lymphoma. Although it cannot cure it, it can consolidate the effect and reduce the recurrence rate. Autologous stem cell transplantation refers to maximizing the killing of lymphoma cells and transplanting autologous stem cells into the body to restore hematopoietic and immune functions as soon as possible after giving the patient an intense pretreatment of radiotherapy and chemotherapy. Autologous stem cells can come from bone marrow or peripheral blood, and autologous stem cell transplantation has no rejection reaction, so it is more effective. Although autologous stem cell transplantation and radiotherapy and chemotherapy cannot treat lymphoma fundamentally, they are more effective in consolidating the therapeutic effect and have better results. Not all lymphoma patients are suitable for autologous stem cell transplantation, doctors will consider the indications and contraindications according to the condition of the patient to determine whether the patient is suitable for this treatment.
