title: Establishment of a new cell line (TAYA) of clear cell adenocarcinoma of the ovary and its radiosensitivity.
abstract: A new cell line (TAYA) was established from ascites of a patient with clear cell adenocarcinoma of the ovary, and the sensitivity of the cell line to various anticancer drugs and radiation was investigated. The 50% growth inhibitory concentrations (IC50) (nM) of various anticancer drugs were: cisplatin >10,000, paclitaxel 80, SN-38 (irinotecan metabolite) 460, and gemcitabine >10,000, showing that the cells had a low sensitivity to these anticancer drugs. In contrast, the 50% growth inhibitory dose (ID50) of radiation was 1.8 Gy, showing that the cells were highly sensitive to radiation. Thus, radiotherapy may be effective for treatment of clear cell adenocarcinoma of the ovary.
