[Autologous bone marrow transplantation in intestinal carcinoma]

Although adjuvant chemotherapy has made some progress in the treatment of colorectal cancer, chemotherapy of metastatic disease remains disappointing. Autologous bone marrow or stem cell transplantation following supralethal chemotherapy is presently not of major significance in tumors of the intestine. The registry of the EBMT (European Cooperative Group for Blood and Marrow Transplantation) contains at March 1993 a total of 2085 cases of autotransplants for solid tumors, of which only 19 were performed for disseminated gastrointestinal cancer (15 gastric, 4 colon). It remains to be shown, whether the presently poor results can be improved upon inclusion of lymphokine-activated killer cells (LAK-cells) by use of cytokine combinations or by the use of tumor infiltrating lymphocytes (TIL) post transplantation.
