Preliminary report of an immunological study in urological cancer

In this study, 32 cases of cancer of the genito-urinary tract are discussed from the viewpoint of immunology. In eight cases treated surgically, there has been no evidence of recurrence over a period of 1-4 years. Those with a good immunological response have a satisfactory course. Patients with a good response have been treated by radical surgery depending on the stage of the tumour, whilst those with a poor response have been treated less radically by reduction of the tumour mass in the hope that a better response may develop. The authors of this report feel that the 'inhibition of the lymphocyte migration test' is a very important factor to evaluate in the study and immunological evolution of the patient. Also, and concerning cases with good immunological response, the poor results after surgery makes us consider the importance and value of blocking factors of the serum closely related to the B type lymphocytes.
