Background Allogeneic hematopoietic stem cell transplantation has proved to be
an effective therapeutic option in various hematologic neoplastic disorders.
Because patients with advanced cutaneous T-cell lymphoma have a poor prognosis,
with minimal possibilities of sustained remission, we studied the therapeutic
potential of hematopoietic stem cell transplantation.
Observations Three young patients with refractory tumor stage mycosis fungoides underwent
allogeneic HLA-matched sibling transplantation with combined marrow and CD34-enriched
peripheral blood stem cell transplantation after cytoreductive chemotherapy
and total-body irradiation. Complete and sustained clinical and histologic
remission was achieved in 2 patients, and both remain disease free 4
years and 15 months later. One patient was in complete remission for 9 months,
followed by limited cutaneous recurrence. Mild graft-vs-host disease and graft-vs-tumor
effect have contained the recurring disease as a low-grade process.
Conclusions Allogeneic hematopoietic stem cell transplantation has the potential
for sustained remission and the possibility of cure for young patients with
advanced and recalcitrant cutaneous T-cell lymphoma. Even in the absence of
complete remission, an allogeneic graft-vs-tumor effect may provide an immune
mechanism to control the malignant T-cell process and alter the natural history
of disease.
