[Correlation of the immune profile with local immunocyte infiltration in urinary bladder tumours (author's transl)]

In 40 patients with urinary bladder tumours we compared the results of the immune profile, obtained by means of cutaneous tests with dinitrochlorobenzene (DNCB), and the infiltration of immunocompetent cells in the histological pattern after transurethral tumour resection. It was noted that the more the tumour had infiltrated, the less was it possible to immunize with DNCB or to achieve an immunocyte infiltration in the tumour. According to the classification of the WHO there was a positive reaction in 56-67% and a correlating immunocyte infiltration in 50-73%.
