BACKGROUND: As mammographic screening becomes more widespread, larger
numbers of tumours are diagnosed while small and node negative. METHODS: We
examined detection mode, tumour size, node status, histological type,
therapy and outcome in 1053 breast cancers diagnosed in one county of the
Swedish Two-County Trial of mammographic screening for breast cancer.
RESULTS: Of patients undergoing total mastectomy with axillary dissection,
65% were found to be node negative. For tumours of size 1-9 mm, 95% were
node negative. The major effects on survival were tumour size, node status
and histological type. Primary adjuvant therapy had no significant
association with survival. CONCLUSIONS: The advent of mammography has
substantially enhanced the possibilities for less radical treatment. There
is an urgent need for therapeutic trials utilizing
mammographic-pathological correlations to ascertain in advance which
tumours can and which cannot benefit from more radical therapy.
