Hodgkin's Lymphoma is a hematologic malignancy with a wide range of therapeutic options that must be chosen according to the stage and the prognostic classification of each patient. The overall survival of patients treated for classic Hodgkin's Lymphoma is increasing significantly, with current cure rates being between 80% and 85%. Nevertheless, 20% to 25% are refractory to the initial treatment and about 30% relapse after having reached a complete response. Patients that have failed standard therapy still have a second chance of cure if they present chemosensitivity to cure schemes, followed by one type of hematopoietic stem cell transplantation (TCTH). Autologous TCTH is an attractive strategy for Hodgkin's Lymphoma patients that fail in the conventional standard therapy. The results in terms of overall survival and disease-free survival are higher than the cure schemes with conventional chemotherapy. This procedure addresses the cure in 50% of chemosensitive patients in second remission, and can lead to lasting remissions for those with more than two lines of treatment. Today, allogeneic TCTH, basically with reduced intensity conditioning (RIC) is indicated for patients with premature relapse after autologous TCTH or for young patients refractory to one or more lines of conventional treatment.
