METHOD FOR EVALUATION OF SENSITIVITY OF CANCER-TISSUE-DERIVED CELL MASS OR AGGREGATED CANCER CELL MASS TO MEDICINAL AGENT OR RADIOACTIVE RAY

摘要

Disclosed is a method for evaluating the sensitivity to a medicinal agent or a radioactive ray using a novel cancer-tissue-derived cell mass or aggregated cancer cell mass which can reflect the behavior of cancer cells in vivo accurately. Firstly, the cancer-tissue-derived cell mass or aggregated cancer cell mass is prepared from an individual. The evaluation is achieved by applying a medicinal agent or a radioactive ray to the novel cancer-tissue-derived cell mass or aggregated cancer cell mass in vitro, and evaluating the state of growth of the cancer-tissue-derived cell mass or aggregated cancer cell mass, determining whether the cancer-tissue-derived cell mass or aggregated cancer cell mass is dead or alive, or analyzing a signal from the cancer-tissue-derived cell mass or aggregated cancer cell mass.
