Mammakarzinom - Adjuvante Mitbestrahlung der Lymphabflussgebiete nach Mastektomie oder Brusterhaltender Operation

Data from 264 patients with surgically treated breast cancer were
retrospectively analysed with regard to the treatment effect of
extending the adjuvant radiotherapy to include the axillary,
intrammamarian, or supraclavicular lymph nodes. The rate of nodal
recurrence was 2,7% after extended therapy and 0,8% after local
therapy alone. Relapse-free survival was significantly longer after
local therapy alone that after extended therapy. The only
significant factor in the Cox model was T-status, which dominated
over the treatment effect.
