High-dose therapy and transplantation for low-grade lymphoma.
Because of the indolent natural history of low-grade lymphomas, long follow-up is needed to assess the overall success of high-dose therapy and autografting. Results to date suggest that patients with brief first or second remission with chemotherapy or those who attain only a partial remission with second-line or subsequent chemotherapy, but remain drug sensitive, may enjoy prolonged remissions relative to conventional treatment. The role of autografting in first remission is uncertain because the data from clinical trials are not mature. Furthermore, the risk of myelodysplasia after transplantation, the broad range of therapeutic alternatives available, and the option to give high-dose therapy upon relapse argue against autografting as primary treatment. Although purging the autograft of residual lymphoma as assessed by molecular methods has been associated with longer remission duration in one major center, the data from published series are remarkably similar, whether the graft was purged or not. Promising anecdotal data suggest that allogeneic transplantation for low-grade lymphoma deserves further study in prospective clinical trials.
