The usefulness of pretreatment DNCB in 85 patients with squamous cell carcinoma of the upper aerodigestive tract

Abstract

Pretreatment DNCB skin testing and absolute lymphocyte counts were studied in 85 consecutive head and neck cancer patients. All patients were treated primarily with radiation therapy alone or combined radiation plus surgery. The results of DNCB testing and absolute lymphocyte counts were not sufficiently predictive of outcome, (no evidence of disease after 2 years) to be useful in making treatment decisions on an individual patient. This applied to the good prognosis (T1, T2, N0-N3) and poor prognosis (T3, T4, N0-N3) groups.
