Figure 1. The Impact of HPV Status and Smoking History Following Re-irradiation with SBRT for Locally-Recurrent Previously-Irradiated Squamous Cell Carcinoma of the Oropharynx.

Figure 1

HPV positivity (OS = 13.63 months) did predict for better overall survival versus patients with HPV negative (OS = 6.88 months) tumors (P = 0.024). Smoking status did not predict for improved OS (P = 0.707) (data not shown).
