Treatment of Early-Stage p16 (HPV)-Positive Squamous Cell Carcinoma of the Tonsil (Oropharynx)

This protocol addresses patients with squamous cell carcinoma of the tonsil in the oropharynx whose tumor is confirmed p16 (HPV)-positive and presents at an early clinical stage — a sub-population with distinct management considerations.

Clinical Scenario
  • Primary site: tonsil, oropharynx — squamous cell carcinoma
  • HPV status: p16-positive (confirmed by IHC)
  • Early clinical stage: T1–2, N0 — or T0–2, N1 with a single node ≤ 3 cm

p16 immunohistochemistry (IHC) testing of the tumor is required to confirm eligibility for this sub-population.

Treatment Approach (Partial Overview)

Single-modality treatment targeting both the primary tumor and the neck is the foundation of management for this early-stage, HPV-positive presentation. Approaches include surgical and radiotherapeutic options, with combined-modality strategies considered in certain node-positive cases; clinical trial enrollment is also an option.

Complete treatment selection, sequencing, dosing framework, and eligibility criteria are detailed in the full structured protocol.
