For the purpose of designing more successful cancer research, the strategy for cancer study in the field of Traditional Korean Medicine(TKM) during the 21th century was examined from the analysis of trends on cancer study in traditional korean medicine. The results were summarized as follows: 1. So far cancer research in TKM was chiefly done on cytotoxicity, side-effects by chemotherapy, tumor immunology, apoptosis, survival time with S-180 and pulmonary colonization assay and also clonogenic assay, cell adhesion assay, angiogenesis, cell-differentiation and side-effect by radiotherapy were partly performed. 2. It may be ideal that we should study synergistic effect between constituent drugs of prescriptions, tumor immunology, combined therapy between western and oriental medicines by reducing side-effect by radiotherapy and chemotherapy and antimetastasis according to the characteristics of oriental medicine chiefly and also supplement the studies on molecular biology, gene therapy, angiogensis and signal transduction. 3. We had better do specific-field research in cooperation between oriental medical colleges and Korea Institute of Oriental Medicine(KIOM) as well as study a target cancers such as hepatic cancer, pulmonary cancer and gastric cancer more intensively than all cancers domestically. 4. Our country must keep communication with China having many clinical data, Taiwan chiefly doing the combined tharapy between oriental and western medicines, Japan having done basic study actively on cancer.
