Total lymphoid irradiation in progressive bronchiolitis obliterans syndrome after lung transplantation: a single-center experience and review of literature.

Limited results about treatment with total lymphoid irradiation (TLI) in lung transplant (LTx) recipients suffering from progressive bronchiolitis obliterans syndrome (BOS) have been reported. We performed a retrospective analysis of all LTx recipients undergoing TLI for progressive BOS in our center, focusing on long-term outcomes regarding overall survival and lung allograft function. Treatment with TLI (2004-2017, n = 20, 1 BOS stage 1, 6 BOS stage 2, and 13 BOS stage 3) resulted in significant attenuation of the FEV -decline in the majority of patients, mainly in those with a rapid decline (P = 0.
