Neurologic complications after irradiation of malignant tumors of the testis.

Of 156 consecutive patients with malignant tumor of the testis 99 were alive two years after treatment. Of these, 12 had radiation-induced neurologic complications which, in 5 instances, consisted of persisting, wholly or partially disabling paresis in the lower limbs. Five had mild, transient symptoms and had persisting symptoms which were not incapacitating. In all those with disabling symptoms the irradiation dose had been higher than 1 600 reu, corresponding to 54.5 Gy over 6 weeks with daily fractions 5 days a week.
