[Serologic analysis of tumor antibodies in the sera of patients with carcinoma of the larynx (author's transl)].

Sera of 20 tumor patients with squamous cell carcinoma of the larynx were evaluated for the presence of antibodies against a soluble antigen from cultured carcinoma cells of the larynx. The antibody levels of the tumor sera were significantly higher than those of the control group. An immunological response was also observed in sera from the control group (55%).
