Surgery of primary retroperitoneal tumours.

Upon detecting 112 retroperitoneal space-reducing processes the authors operated on 62 adults with primary retroperitoneal tumours (12 benign and 50 malignant). The diagnostics and complex therapy of these tumours are dealt with. It is established that although the CR, MRI and USG have resulted in a considerable development, the therapeutic results are still not much better.

Comparative evaluation of manual and instrumental rectum resections.

The authors compared the perioperative results of 125 + 125 Dixon operations performed at two time intervals (1956-1979 and 1985-1990), the postoperative recurrences and the survival data. It is established that, from the anastomosis point of view, the instrumental resections--beside their rapidity and favourable sterility--are safer interventions associated with less complications. With respect to local recurrences the two methods do not differ significantly.

Occult breast cancer presenting with axillary metastasis.

The literature of occult breast cancer is reviewed and the management of our 43 patients is discussed. In 20 patients mastectomy and axillary block dissection, in nine upper-outer quadrant resection of the breast with axillary block dissection, and in two axillary biopsy were carried out. The primary tumour was found only in 11 patients during the first operation, either by macroscopic or microscopic examination.

[Occult breast cancer causing axillary metastasis].

Authors review 43 cases of occult breast cancer selected from 6396 patients operated on for breast cancer in the National Institute of Oncology, Budapest over a 20-year period (1972-1991). In 20 patients mastectomy and axillary block dissection, in 9 upper-outer quadrant resection of the breast with axillary block dissection, in 12 only axillary block dissection, and in 2 axillary biopsy were carried out. The primary tumor was localized only in 11 patients during the first operation either by macroscopic or by microscopic examination.
