Autologous hematopoietic stem-cell transplant in small-sized and peripheral centers: a 10-year experiment

Along with continuing changes in therapeutic modalities, indications of autologous hematopoietic stem-cell transplantation (ASCT) have been emerging and changing considerably, especially in the era of targeted therapy and small molecule inhibitors. Patients treated with novel agents tend to have a longer survival period, thus eventually reaching higher ages at ASCT. Herein, and to address the question of ASCT outcomes in small, community-based, peripheral French centers, we report the 10-year follow-up results of 136 patients who received ASCT in our eight-bed ASCT unit, situated in an urban area.

We retrospectively analyzed a cohort of 136 patients treated between 2008 and 2017 at the Duchenne Hospital Center. Of these 136 patients, 75 underwent ASCT for myeloma, while 61 underwent ASCT for lymphoma, amongst which 57 patients were treated for B-cell lymphoma. The median age was 65 years (range, 27-72) for myeloma patients, and 62 years (range, 27-71) for patients with lymphoma.

The cohort median follow up was estimated at 33 months; 10-year overall survival (OS) and progression-free survival (PFS) were 71% and 64% for B-cell non-Hodgkin lymphoma, and 75% and 45% for myeloma, respectively. No statistically significant differences were found for OS or 1-year PFS between patients who received ASCT from 2008 to 2012, and those who received it from 2013 to 2017.

In the absence of randomized trials studying the role of center size, experience, and standardization procedure for ASCT outcome, these results may suggest that ASCT in peripheral accredited small-sized centers could be a viable option to facilitate follow up and enable access to this treatment, especially for elderly patients, in comparison with referring the patient to central large hospitals to undergo ASCT.
