- US Multi-Institutional
- Randomized. 46 patients with progressive multiple sclerosis. Arm 1) Modified total lymphoid irradiation (TLI) + low dose prednisone vs. Arm 2) sham TLI + identical prednisone. Modified TLI given as AP/PA 19.8/11 using modified mantle and smaller inverted Y, excluding spleen and ovaries
- 1997 PMID 9415539 -- "Modified total lymphoid irradiation and low dose corticosteroids in progressive multiple sclerosis." (Cook SD, J Neurol Sci. 1997 Nov 25;152(2):172-81.)
- Outcome: Fewer TLI patients showed sustained decline (SS); risk for relapse reduced 54% (SS); fewer new MRI lesions (SS)
- Toxicity: mild
- Conclusion: Total lymphoid irradiation and systemic immunosuppression have beneficial effect in progressive forms of MS
