On the other hand, for treatment of patients with metastatic brain tumors, which indicates advanced cancer, surgery and irradiation are mainly performed since the response rate to chemotherapy is low. To improve the prognosis of patients with cancer, many chemosensitivity tests, either in vitro or in vivo, have been tried to predict the efficacy of anticancer agents in individual patients before administration. However, no test that possesses high reproducibility, rapidity, convenience, low cost and good predictability has been developed so far. In this study, the usefulness of the chick embryo assay as an in vivo chemosensitiv­ity test and also as an experimental model for brain metastasis was evaluated. First, rat C6 glioma cells were grafted on the Chorioallantoic membrane (CAM) of chick embryo. This grafting was used to examine the effect of anticancer drugs. Then, 67 surgical specimens including benign tumors were examined by this method. All the tumor specimens tested had been grafted on the CAM ; the evalu­able ratio was 100%. Effectiveness ratios of ACNU, MCNU and CAP therapy for 22 specimens of glioblastoma, were 30.0, 50.0 and 18.8%, respectively. Effectiveness ratios for 7 specimens of anaplastic astrocytoma, were 28.6, 42.9 and 14.3%, respectively. Among them, 23 instances of previ­ously untreated malignant glioma were. evaluated retrospectively to predict the clinical effects, judged by computed tomography. There were 6 (55%) instances in which the assay response correctly corre­sponded to a clinical response (true-positive). There were 5 (45%) false-positives for the assay, 0 (0%) false-negative and 12 (100%) true-negatives. The overall predictive accuracy was 78% (18/23). Thus, a high-degree of positive association exists between this assay and the clinical outcome. Moreover, as an experimental model for brain metastasis, murine B16-F10 melanoma cells were transplanted into the blood vessel on the CAM and the antitumor effects of ACNU, MCNU and CAP therapy on metastasi加d melanoma cells in the brains of chick embryos were examined. The drugs which passed through the blood-brain barrier, were effective in this assay system. These results indi­cate that this in vivo assay system using the chick embryo is a promising method in predicting clini­cal response in the treatment of malignant brain tumors and is also is a useful experimental model for brain metastasis.
