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

摘要

in vivoin vitroDisclosed 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 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 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.
