Pattern of metastases in human breast carcinoma in relation to estrogen receptor status

Anticancer Res. 1986 Jan-Feb;6(1):107-11.

Abstract

The distribution of metastases at the first recurrence of breast cancer was studied in 57 estrogen receptor (ER) positive and in 23 ER negative patients, who constituted a subset of 460 patients with operable breast cancer. The pattern of metastases with respect to localization of metastases and the dominant site of first recurrence was similar in patients with ER positive and ER negative tumours. The recurrence-free survival (RFS) and the overall survival were associated with the ER status in the 460 patients. ER positive patients had both a significantly longer RFS (p = 0.0024) and survival (p = 0.0001) compared to ER negative patients. Survival after recurrence was prolonged in patients with soft tissue recurrences only, and the proportion of dead patients was highest in receptor negative patients with metastases to bone and viscera. In conclusion, we could not demonstrate that ER positive and negative tumours have a propensity for recurrence at specific sites.
