  • Title: Improvement of impaired leukocyte migration inhibition by thymosin in patients with head and neck squamous carcinoma.
    Author: Wolf GT, Kerney SE, Chretien PB.
    Journal: Am J Surg; 1980 Oct; 140(4):531-7. PubMed ID: 6999927.
    Abstract:
    In a preliminary study of the effects of SK-SD and thymosin on leukocyte migration inhibition in patients with squamous carcinoma of the head and neck, the cancer patients had significantly lower leukocyte migration inhibition of SK-SD than normal subjects. Thymosin increased the inhibition to SK-SD in the cancer patients to levels similar to those in normal subjects, and decreased the inhibition in normal subjects. These results confirm and extend the results of previous studies of the effects of thymosin in vitro, which show restoration of immune reactivity in patients with impaired cellular immunity and either no effect or a decrease in immune reactivity in subjects with normal cellular immunity. These combined observations provide a rationale for determining the clinical effects of thymosin in immunoincompetent patients with head and neck cancer and suggest that immunorestorative agents such as thymosin be used with caution in patients with normal cellular immunity.
