Two long-established and seven newly established endometrial adenocarcinoma cell lines were tested for their capacity to repair sublethal damage after fractionated irradiation. Cell survival was determined with the 96-well plate clonogenic assay based on limiting dilutions. Total radiation doses of 0.75 Gy, 1.25 Gy, 2.50 Gy, 5.00 Gy and 7.50 Gy were used either as a single dose or divided into two or three equal fractions with a 24 h interval. Survival data were fitted to the linear quadratic model, and the area under the survival curve (AUC), equivalent to the mean inactivation dose, was obtained with numerical integration. The amount of sublethal damage repair (SLDR) was expressed as an area-under-the-curve (AUC) ratio comparing survivals from fractionated-dose with those from single-dose experiments. SLDR capacity of the cell lines expressed as an AUC ratio varied between 1.00 and 1.59, and the mean was 1.17. Two highly radiosensitive cell lines were found to be SLDR-deficient, but most of the cell lines studied had some SLDR capacity. We have earlier shown that endometrial cancer cell lines as a group are more radiosensitive than squamous-cell carcinoma (SCC) lines. Data obtained in this study suggest that the capacity for SLDR in these cell lines is rather limited compared with the majority of SCC lines tested. This finding underlines further the high radioresponsiveness of endometrial cancer.
