Immunosuppressive drugs used in the management of heart and lung transplants have a large monetary and quality of life cost due to their side effects. Total lymphoid irradiation (TLI) is one method of minimising the need for or replacing post-operative immunosuppressive drugs. A literature review was conducted on electronic databases using defined search terms. The aim was to establish the indi...

PURPOSE The presence of a pronounced tumor lymphocytic infiltrate (TLI) is deemed to reflect the presence of an immunoinflammatory response against the tumor and may thus have prognostic significance. We investigated the prognostic value of TLI detected in pathological specimens collected following neoadjuvant chemotherapy (NACT) in patients with breast cancer. METHODS 100 consecutive patient...

In this study, we investigated the influence of some of the variables of the thymidine labeling index (TLI) in human colorectal carcinoma. These variables were: cell suspensions versus tissue fragments; incubation with 5-fluoro-2'-deoxyuridine; method of tissue procurement; location in the large bowel; and TLI distri bution in different areas of the tumor. Mean TLI values for cell suspensions a...

To determine predictive factors for temporal lobe injury (TLI) in nasopharyngeal carcinoma patient (NPC) treated with intensity-modulated radiation therapy (IMRT). A total of 695 NPC cases treated with IMRT were retrospectively analyzed. TLI was diagnosed on MRI images. Volume-dose histograms for 870 evaluable temporal lobes were analyzed, and the predictive factors for the occurrence of TLI wa...

Preconditioning with the nonmyeloablative regimen total lymphoid irradiation (TLI) before hematopoietic cell transplantation facilitates the establishment of mixed chimerism and protects against graft-versus-host disease. We reported that the development of mixed chimerism requires interleukin (IL)-4 and is associated with increased host anti-donor TH2 cells, but the effect of TLI on the differ...

The concept of using total lymphoid irradiation (TLI) for immunosuppression is based on the prolonged and profound immunosuppressive effects observed after TLI in the treatment of patients with Hodgkin's disease. Pre-operative TLI of allograft recipients has been shown to be immunosuppressive when used alone or together with chemical immunosuppression. Fractionated TLI and allogeneic bone marro...
