[The L.A.I. test and tumor markers (Ca 19-9 and TPA) in the diagnosis of pancreatic carcinoma].

A particular cell-mediated immune response is tested in this work: the leukocyte adherence inhibition (L.A.I.) in the presence of organ tumor antigens. Forty-two patients suspected of having pancreatic cancer were submitted to the L.A.I. test and Ca 19.9 and TPA determination. The diagnosis of pancreatic cancer was eventually surgically confirmed and staged in 30 patients. The most important features of the L.A.I. test were good specificity (94%) and the ability to diagnose stage I cancers (3/4 cases, 75%), while the other markers are more likely to diagnose more advanced stages. The L.A.I. test seems to be also useful during the follow-up period since its positivity may even be some months previous to the clinical symptoms. During follow-up the L.A.I. test proved useful in supervising the neoplastic disease course from the moment of relapse to advanced clinical symptoms.
