Abstract

Proliferative activity, evaluated as [3H]thymidine labelling index ([3H]dT LI), and hormone receptors were determined on 97 primary breast cancers and on metachronous lesions from the same patient. Overall, the [3H]dT LI of metachronous lesions was significantly higher than that of the primary tumour (P = 0.003). Hormone receptor profiles of the two lesions were similar in about 75% of the cases; disagreements were mainly due to a disappearance of hormone receptors in metachronous lesions. In contralateral tumours, [3H]dT LI and hormone receptors were unrelated to those of the relative primary lesion. In this series of relapsing patients, [3H]dT LI was unrelated to hormone receptor status in the primary tumour, but it was higher in the metachronous lesions from patients with hormone receptor-negative primary tumours. For patients given no systemic therapy between surgery and relapse, the time to develop local-regional recurrences or contralateral tumours was inversely related to the [3H]dT LI of the metachronous lesions.
