RESUMEN
From 1976 through 1984 46 patients with locally advanced breast cancer were treated by either radiotherapy alone or by combination of surgery and postoperative radiotherapy. Eleven of the 21 patients treated by radiotherapy alone had a local or regional recurrence, while no recurrences occurred in the combined treatment group. From this study it was concluded that "locally advanced" breast cancer is a heterogeneous disease and that further study concerning the role of surgery is justifiable for a selected subgroup of patients with non-inflammatory resectable tumours (meeting the criteria of "locally advanced" breast cancer).

In a group of 14 patients with chronic renal failure and secondary hyperparathyroidism, subtraction scintigraphy with 201Tl and 99mTc for parathyroid localisation was performed prior to subtotal parathyroidectomy. Fourteen of 38 (37%) enlarged hyperplastic glands found at first operation corresponded with the hot spots seen on the preoperative scans. Four of five (80%) found at a second operation had also been detected this way preoperatively. Postoperative scans were performed in nine patients. All hot foci seen on the preoperative scans had disappeared. In two patients new hot spots emerged correlating with known residual parathyroid tissue, and also in one patient with recurrent secondary hyperparathyroidism. We conclude that this diagnostic method is of limited value prior to the first neck exploration in secondary hyperparathyroidism of chronic renal failure. However it might be a useful method in the evaluation of patients with signs of persistent or recurrent hyperparathyroidism.
