Enteropathy-associated T-cell lymphoma (EATL) is a T-cell Non-Hodgkin Lymphoma which is highly associated with celiac disease. The prognosis of EATL has been considered poor and there are no standardized treatment protocols. Here, we evaluate treatment response and survival of EATL patients in a large multicenter cohort. A total of 61 patients diagnosed with EATL were analyzed. Various treatment regimens were applied in EATL during the past fifteen years including either monotherapy consisting of chemotherapy or resection, or combination therapy with both aforementioned regimens whether or not combined with stem-cell transplantation (SCT). Overall, 50/61 patients (82%) died after a median of 7.4 months. One- and five-year overall survival was 40 and 11%, respectively. Median follow-up in the survivors was 26 months. Patients treated with the most aggressive treatment, that is, resection, chemotherapy and autologous SCT, showed the most favourable outcome with complete remission in all patients, the lowest relapse rate and one- and five-year overall survival of 100 and 33%, respectively, although overall survival in this group was not significantly better as compared to patients treated with surgery and chemotherapy. This study indicates that combination treatment is superior compared to monotherapy. Whether or not consolidation therapy with autologous SCT may improve survival needs to be substantiated in a larger randomized international trial.
