In the last decade, immunomodulation has emerged as a mode of therapy
capable of mediating the regression of cancer in some patients. This a
rticle reviews our experience with immunomodulation following transpla
nt and non-transplant chemotherapy. We used interferon and cyclosporin
e A following conventional chemotherapy in a non-transplant setting fo
r a B16 melanoma in a murine model. This combination generated cells w
ith MHC-unrestricted cytotoxicity. We have also used immunotherapy in
the transplant setting with IL-2 activated PBSC in patients with breas
t cancer. Of the 28 patients treated, 20 developed GVHD and the averag
e time to reconstitution was 12 days (comparable to a control group).
This article also raises the possibility of extending immunomodulation
to breast cancer patients in the nontransplant setting to induce an a
ntitumor immune response following cytoreductive chemotherapy.
