    Abstract:
    Humoral antitumor response of Lewis lung tumor-bearing mice was measured by humoral leukocyte adherence inhibition (H-LAI) test. The reactivity of serum against tumor antigens prepared from primary tumor and lung metastases could be revealed at the first day after injection of tumor cells. On the other hand, the macroscopical appearance of the primary tumors and lung metastases was observed after 5 and 11 days, respectively. These findings suggest that the immune reaction of the host could be detected by H-LAI test earlier than the tumor can manifest itself. The antigens prepared from primary tumors and metastases seemed to be very similar, however, the metastasis antigen had additional determinants as detected by the H-LAI technique. Comparison of two tumor lines, the original Lewis lung tumor (LLT) and its variant with high metastatic capacity (LLT-HH), showed high similarity between their antigens as tested in H-LAI system by cross-reaction probes.
