title: [Restoration of antineoplastic reactivity of the leukocytes after preincubation].
abstract: Specific antitumor sensitization in patients with carcinoma of the stomach was revealed by means of the leukocyte migration inhibition test. After 24-hour preincubation at 4 degrees C in a serum-free medium the areactive leukocytes from patients with carcinoma of the stomach (stages III--IV) acquired the ability to react specifically to allogeneic antigens of the tumor of the same localization. Preincubation did not influence the inhibition of migration of leukocytes in non-tumor patients by stomach carcinoma antigens. The supernatant of preincubated leukocytes of tumor patients contained substances that inhibited migration of indicator leukocytes.
