  • Publication number: 20140128272
    Abstract: Provided are a method for retaining in a dormant state a cancer tissue-derived cell mass that can reflect accurately the in vivo behavior of cancer cells, and an evaluation method for examining the sensitivity to various treatments including a drug sensitivity test by using a cancer tissue-derived cell mass in such a dormant state. The cancer tissue-derived cell mass is prepared from an individual. Such a cancer tissue-derived cell mass is cultured in vitro under the conditions of hypoxia and low levels of growth factors. Furthermore, a treatment with a drug, etc. is applied in vitro to the cancer tissue-derived cell mass in the dormant state so that evaluation is achieved by examination of its proliferation state, determination of life and death, and analysis of signals.
