High Dose Steroid Therapy (Prednisone or Methylprednisolone) for the Improvement of Symptoms of Late Radiation-Associated Lower Cranial Neuropathy in Oropharyngeal Cancer Survivors

This phase I/II trial studies the side effect and best dose of steroid therapy (prednisone or methylprednisolone) in improving symptoms of late radiation-associated lower cranial neuropathy in oropharyngeal cancer survivors. Steroid therapy with prednisone or methylprednisolone may help to improve symptoms associated with late radiation-associated lower cranial neuropathy.

PRIMARY OBJECTIVE:

I. To establish feasibility and maximum tolerated dose (MTD) of steroid therapy that provides symptomatic improvement in oropharyngeal cancer (OPC) survivors with late lower cranial neuropathy (LCNP).

SECONDARY OBJECTIVE:

I. To examine endpoints that may be sensitive to functional or symptomatic gains with steroid therapy for late LCNP in OPC survivors by characterizing changes in symptoms, functional status, quality of life (QOL), neurophysiology, and imaging studies after steroid therapy.

TERTIARY OBJECTIVE:

I. To establish a hypothesis-generating database of physiologic, functional, and patient-reported outcomes (PROs) among head and neck cancer (HNC) survivors with late lower cranial neuropathy treated with steroid therapy.

OUTLINE: This is a phase I, dose-escalation study of steroid therapy followed by a phase II study.

Patients receive prednisone orally (PO) (or by feeding tube) once daily (QD) on days 1-5 and then taper off over 2 weeks or methylprednisolone intravenously (IV) over 1 hour on days 1-5 in the absence of disease progression or unacceptable toxicity.
