On radioactive labelling of the lymph drainage regions of the pelvis.

The introduction of radioisotopes in the surgical management of cervical carcinoma at our clinic in 1970 constituted a major advance in this respect. Prior to surgery the lymphatic tissue of the pelvic region is labelled by subcutaneous applications of radioisotopes. Our experience shows that the body's kinetics encourage the deposition of the radionucleide and thus visualization even of the groups of lymph nodes located in the deeper layers of the pelvic region. This method allows virtually complete lymphonodectomy with resultant improvement of cure rates.
