[DNFB reaction in bladder cancer, an immunological study]

It is stated that the determination of the reactivity against the primary antigen dinitrofluorbenzol by means of the epicutaneous skin test before the beginning of a therapy may give an essential reference to the spreading of the tumour and to the prognosis. The course control in patients with carcinoma of the urinary bladder should therefore consist not only of clinical but also of immunological examinations.
