After former radical extensions the breast cancer surgery now tends to accept the necessary minimum principle. There are surveys which rated the local recurrence to the width of the intact margin around the tumour; they are aware of the decisive role of extensive intraductal component to have an influence on the local recurrence. Leaving out irradiation in selected groups is a part of the less aggressive tendency of breast cancer treatment. The omitment of the routine use of axillary dissection is under further consideration as well. The intraoperative mapping of lymph nodes looks promising in assessing their tumorous involvement. The prognostic role of dissection can be replaced by the immunoreactive hepatocyte growth factor. Timing of the operation adjusted to the menstrual phase seems to improve the survival in case of those patients who were operated on in the luteal phase.
A bacterial inoculum was positioned intraperitoneally and retroperitoneally in animals who had been treated with various antibiotic programs. The results indicate that the retroperitoneal tissue is more resistant to severe infectious complications than the general peritoneal cavity.
Bei Ratten wird durch eine Omentektomie die Immun-Erythrophagocytose der Leukocyten stark herabgesetzt. Nach den experimentellen Untersuchungen der Autoren steht das Omentum mit der mobilen, cellulären Schutzvorrichtung des Organismus ebenfalls in Zusammenhang. Die Versuchsdaten wurden durch statistische Berechnungen erhärtet.
