[Immunologic control in patients with cancer of the gastrointestinal tract]

Blastic transformation in vitro was used to estimate immunological competence in patients having gastrointestinal cancer. The authors found a correlation between lymphocyte transformation by phytohemagglutinin and prognosis. Autologous plasma inhibited lymphocyte transformation, particularly in those patients that proved to have an unfavorable clinical evolution one year after surgery.
