Summary

This is a single institution phase II study that will enroll patients with T0-3N0-2 p16-positive oropharyngeal squamous cell carcinoma (OSCC) undergoing resection of all gross visible disease at the primary site and in the lymph nodes.

Conditions

  • Oropharyngeal Cancer
  • Carcinoma

Interventions

DRUG

Cisplatin

Low risk pathology with post-op HPV DNA (-): cisplatin-based chemoradiation with 30 Gy in 15 fractions and 3 cycles of weekly cisplatin 40mg/m2 IV on Days 1, 8, and 15 of radiation. Low risk pathology with post-op HPV DNA (+): cisplatin-based chemoradiation with 40 Gy in 20 fractions and 4 cycles of weekly cisplatin 40mg/m2 IV on Days 1, 8, 15, and 22 of radiation. High risk pathology with post-op HPV DNA (-), excluding patients with both 5 LN+ and ENE+ or pre-op HPV DNA≤12 copies/mL: cisplatin-based radiation with 40 Gy in 20 fractions and 4 cycles of weekly cisplatin 40mg/m2 IV on Days 1, 8, 15, and 22 of radiation. High risk pathology with post-op HPV DNA (+) OR pre-op HPV DNA≤12 copies/mL OR both 5 or more LN+ and ENE+: cisplatin-based radiation with 50 Gy in 25 fractions with 5 cycles of weekly cisplatin 40mg/m2 IV on Days 1, 8, 15, 22, and 29 of radiation.
