[Interdisciplinary communication in breast-preserving therapy of early infiltrating ductal breast carcinoma].

The goal in breast-maintaining treatment of early mammary cancer means control of the tumor in a cosmetically acceptable breast worthy to be left in place. To this intent, a staged approach with agreement between therapists (surgeon, radiotherapist, oncologist) and pathologist should be used. Morphologic and histopathologic findings are relevant and are age-dependent indicators for risk of local recurrence. The cosmetic result as well as local tumor control depend on clinical findings and techniques of resection. The interdisciplinary communication weighs clinical and morphological criteria for counselling and selection of patients. In the presence of unfavourable prerequisites for cosmetically satisfactory results and increased probability of local recurrence (greater than 20%/5 years), breast-maintaining therapy should not be recommended; however, prognostic criteria do not depend on operative techniques.
