Autologous hematopoietic cell transplantation non-Hodgkin's lymphoma: 100 month follow-up

Abstract

One hundred and ten adult patients with non-Hodgkin's lymphoma (NHL) received an autologous hematopoietic cell transplant (ABMT) from 1988 to 1993. All received a uniform preparative regimen of cyclophosphamide, BCNU and etoposide (CBV). Twenty-one percent had low grade histologies, 54% intermediate grade, and 25% high grade. Median follow-up of 48 survivors is 100 months. Kaplan-Meier 10 year overall survival and relapse-free survival for the entire group is 42% and 32%, respectively. Fifty patients were in complete remission 2 years post transplant. With additional follow-up, patients with high grade malignancies are cured, while patients with intermediate or low grade histologies were at continued risk of relapse up to 5 years post transplant. Of 39 patients in complete remission 5 years post transplant, none have relapsed with additional extended follow-up. We conclude that patients with NHL treated with ABMT, if in CR 5 years post transplant, are at very low risk of relapse with extended follow-up, suggesting the possibility of cure for all histologies, including those with low grade NHL.
