Tumor growth versus time for the different treatments. Tumor volumes measured using the CT images for a subset of rats in each group. Untreated animals (crosses), n = 11; infusion of 127IUdR with osmotic pump 20 mg ml−1 alone (triangles), n = 6; irradiation alone (single fraction of 15 Gy) (open squares), n = 5; or in combination with 127IUdR with osmotic pump 20 mg ml−1 (filled squares), n = 5. IUdR was administrated for six days starting seven days after tumor implantation. The line corresponds to an exponential fit of the `untreated group' survival data. |
