Choice of Radiosensitizer in Baseline Grade-2 Sensorineural Hearing Loss (SNHL) in Head and Neck Cancer

  • Rule of Thumb:
    • Avoid cisplatin in patients with grade ≥ 2 baseline hearing loss 
  • Cisplatin:
    • Is ototoxic and can cause irreversible worsening of SNHL:
      • Risk is cumulative and dose-dependent
  • Alternatives:
    • Cetuximab + Radiotherapy (RT):
      • NCCN-endorsed option for cisplatin-ineligible patients
      • Inferior to cisplatin in HPV-positive disease:
        • RTOG-1016, De-ESCALaTE trials:
          • But appropriate when platinum is contraindicated
  • Carboplatin-based chemoradiation:
    • Some centers use carboplatin (AUC 1 to 2 weekly) ± 5-FU or paclitaxel with RT:
      • Evidence less robust than cisplatin:
        • But can be considered when cetuximab is unsuitable
  • Practice Pearls:
    • Baseline audiogram required in all patients before starting cisplatin or alternatives
    • Avoid concurrent ototoxic drugs:
      • Loop diuretics, aminoglycosides, high-dose salicylates
    • Monitor hearing during therapy if any platinum agent is considered
