- Abstract:
- Clinical evidence and the majority of experimental data suggest a cross-resistance between cisplatin and radiation in ovarian cancer. The authors are not aware of any report of a human ovarian cancer cell line for which the dose-response relationships to both radiation and chemotherapy including paclitaxel and cisplatin have been evaluated with the same methodology. The present study investigated the radiosensitivity profiles of four established human ovarian cancer cell lines in vitro using the ATP assay, which measures total cell kill. The CAOV-3 cell line showed the highest degree of radiosensitivity of the four cell lines. SKOV-3 cells were the most resistant. The BG-1 cell line, previously shown to be highly resistant to cisplatin but sensitive to paclitaxel, was distinctly sensitive to radiation. This was particularly true for the lower dosages (2-6 Gy). The four cell lines tested are a good representation of cell lines with different radiosensitivities. The different response patterns to cytotoxic agents and radiation, make the BG-1 cell line in particular an interesting candidate for future studies on mechanisms of resistance and combination effects between radiation and chemotherapy.
