When compared with placebo for treating immune mediated inflammation post transplantation and in autoimmunity, mesenchymal stromal cells (MSCs) may reduce the all-cause mortality if they are used for a therapeutic reason. Moreover, the therapeutic use of MSCs may increase the complete response of acute and chronic GvHD, but the evidence is very uncertain. The evidence suggests that MSCs for prophylactic reason result in little to no difference in the all-cause mortality, in the relapse of malignant diseases, and in the incidence of acute GvHD. The evidence suggests that MSCs for prophylactic reason reduce the incidence of chronic GvHD.Platelet transfusions may be necessary for those who receive chemotherapy or undergo a stem cell transplantation due to the higher risk for bleeding. When comparing therapeutic/non-prophylactic platelet transfusions to prophylactic platelet transfusions there is little to no difference in the mortality secondary to bleeding and they may result in a slight reduction in the number of days on which a significant bleeding event occurred. The evidence suggests that therapeutic platelet transfusions result in a large increase in the number of people with at least one significant bleeding event and they likely result in a large reduction in the number of platelet transfusions. Other
It is unclear if including aerobic physical exercise, in addition to the standard treatment for adult patients with haematological malignancies, is effective at reducing anxiety and serious adverse effects. Aerobic physical exercises may result in little to no difference in the mortality, in the quality of life and in the physical functioning.
Implants, made from hard metals or silicone, associated with anaplastic large cell lymphoma. Familial component
Familial lymphoid cancer is rare. The familial risk of lymphoma is elevated for multiple lymphoma subtypes, suggesting a shared genetic cause. However, a family history of a specific subtype is most strongly associated with risk for that subtype, indicating that these genetic factors are subtype-specific. Genome-wide association studies  have successfully identified 67 single-nucleotide polymorphisms  from 41 loci, most of which are subtype specific. HIV/AIDS
The Centers for Disease Control and Prevention (CDC) included certain types of non-Hodgkin lymphoma as AIDS-defining cancers in 1987. Immune suppression rather than HIV itself is implicated in the pathogenesis of this malignancy, with a clear correlation between the degree of immune suppression and the risk of developing NHL. Additionally, other retroviruses, such as HTLV, may be spread by the same mechanisms that spread HIV, leading to an increased rate of co-infection. The natural history of HIV infection has greatly changed over time. As a consequence, rates of non-Hodgkin lymphoma (NHL) in people infected with HIV has significantly declined in recent years. Treatment
The traditional treatment of NHL includes chemotherapy, radiotherapy, and stem-cell transplants. There have also been developments in immunotherapy used in the treatment of NHL. Chemotherapy
The most common chemotherapy used for B-cell non-Hodgkin lymphoma is R-CHOP, which is a regimen of four drugs (cyclophosphamide, doxorubicin, vincristine, and prednisone) plus rituximab. Treatment complications
If participants receive stem-cell transplants, they can develop a graft-versus-host disease.
