Application of tube LAI assay in larynx cancer patients

The tube LAI assay was used for long-term follow-up of specific antitumor immunity in larynx cancer patients. A high percentage of patients examined before surgery exhibited positive LAI reactivity, and the success of treatment was reflected in the disappearance of positive LAI reactions. The tube LAI assay may be useful in diagnosing the precancerous states. Finally, positive LAI reactions were observed in hospital staff members exposed to contact with cancer patients over several years.
