[Further facts in pleural recurrence prevention by radio-colloidal gold in operated breast cancer].

The communication deals with endoscopical facts making recognizable that the intrapleural incorporation of colloidal radio-gold after the so-called radical mastectomy corresponds to a preventive-curative act. There is an analysis and proof of lymphogenous nature of the threatening, in it's manifest stage always lethal early and late pleural metastasis. The special and various features of the pleural cavity in postoperative endoscopy are demonstrated as a basis for the following dosage of radio-gold in a preventive-curative sense. Original, spectacular pictures are represented. On the basis of an experience for decades and because of the insufficient results of surgical therapy and conventional radiotherapy, unsatisfactory quoad sanationem et vitam, it must be pointed out that an additional, intrapleural radio-gold therapy is imperative. The application must be done early after operation. The effectiveness of this application is beyond question, since the pioneer-work of J. H. Müller and the ten years results with his preoperative radio-gold infiltration of the breast and my own endoscopically developed intrapleural radio-gold infusion. Both methods make possible true healing and ten years survival. For this reasons I recommend the employ of the more practicable intrapleural infusion on a big collective. The question of a long-term effectiveness of the therapy with fast electrons (betatron) is still to be decided on the ten years parameter. But I don't doubt that radio-gold is superior to all kind of radiotherapy controlling the contralateral pleural dissemination.
