Zusammenfassung
Eine adäquate postoperative Strahlentherapie senkt das
lokoregionäre Rückfallrisiko nach Brustkrebsoperation auf etwa ein
Drittel bis ein Fünftel des ohne Radiotherapie bestehenden Risikos. Das
lokale Rezidiv stellt einen unabhängigen prognostischen Faktor dar. In den
letzten Jahren gibt es zunehmend Hinweise darauf, daß die postoperative
Radiotherapie durch die verbesserte lokoregionäre Tumorkontrolle auch
einen signifikanten Einfluß auf die langfristigen Überlebensraten
hat. Eine Strahlentherapie ist deshalb grundsätzlich bei hohem lokalem
Rezidivrisiko indiziert, also nach allen brusterhaltenden Operationen und nach
Mastektomie bei fortgeschrittenen Stadien (pT3-4 oder ausgedehnter LK-Befall).
Die Risiken einer modernen Strahlentherapie sind gering.
Summary
An adequate postoperative radiation therapy reduces the locoregional
recurrence risk after a breast cancer surgery to about one third to one fifth
of the risk, which is present without radiotherapy. The local relapse is an
independent prognostic factor. During the last years there has been an
increasing number of hints, that the postoperative radiotherapy has a
significant influence on the long-term survival rates due to an improved
locoregional tumor control. Therefore, a radiation therapy is basically induced
in the case of a large local relapse risk, i.e. after all surgeries which save
the breast and after mastectomy in advanced stages (pT3-4 or extensive LC
infestation). The risk of a modern radiation therapy is low.
