A review has been made of lymphographic diagnoses recorded from patients with cervical carcinoma over more than five years. The diagnosis by lymphography of nodes metastases had to be altered in some 25 per cent, and correction proved necessary also in cases in which lymphography had failed to yield conclusive information. - In the group with lymphographically secured cancer lymph nodes coincided with histological results in 70 per cent of all primary and 90 per cent of secondary checks. Comparable gaps were recorded also from the group with lymphographically inconclusive information on lymph node cancer. - The following conclusions are drawn from the study described: (a) The accuracy of lymphographic diagnosis depends on the experiences of the examiner and changes within time and this must be considered in the evaluation of therapeutic success or failure. - (b) Conclusive findings in the context of lymph node problems are obtainable from selective use of lymphography.
