The radiation response of SCCVII tumor cells in C3H/He mice varies with the irradiation conditions.
The radiation response of SCCVII tumor cells in C3H/He mice under various irradiation conditions was studied using an in vivo-in vitro assay. When tumor-bearing mice were irradiated without anesthesia or physical restraint, the tumor had a hypoxic fraction of 5.4%. Both anesthesia and immobilization of the tumor-bearing leg with adhesive tape produced significant increases in the hypoxic fraction (23 and 28%, respectively). Restraining the mouse in a jig without immobilizing the tumor-bearing leg also increased the hypoxic fraction (13%).
