Kaplan meier local control by treatment group. Seven patients in the re-irradiation arm are also counted in one other arm because of recurrence. Compared to radiation therapy (RT) alone, adjuvant RT was not different (p=0.98), but recurrence after prior surgery (p = 0.02) and re-irradiation (with or without prior surgery) groups (p<0.01) were different.
