[A clinical study on adoptive immunotherapy of bone metastatic neoplasm with tumor infiltrating lymphocytes].

In order to establish a more efficient and less toxic approach than lymphokine activated killer (LAK) cell in adoptive immunotherapy (AIT), tumor infiltrating lymphocytes (TILs) were isolated from operation and biopsy samples of 10 patients with bone metastatic tumor during 1990 approximately 1992. TILs activated and expanded in vitro were adoptively transferred to patients with bone metastatic lesions. Complete response in 1, partial response in 2, minor response in 3 and nonresponse in 4 patients with TILs immunotherapy were observed. The effective rate was 30%, P > 0.01. The results of this preliminary study indicate that adoptive immunotherapy with large number of TILs is an encouraging approach in the treatment of advanced neoplasm with bone metastasis.
