[Clinical features of recurrent breast cancer--factors related to prognosis]

Influencing factors related to clinical appearances of recurrent breast cancer for the prognoses were studied. Stages of the disease at the time of the first surgery were highly related to the disease free interval (DFI) and the survival after the recurrence. Positivity of estrogen receptor in tumor tissue was found to be correlated with prognoses. The prognosis was also influenced by the first recurrent site. The patients with liver metastases which found as the first recurrent site showed shorter survival, on the other hand, the patients with metastases at soft tissue or bone showed relatively longer survival. The comparative analysis was performed in terms of the factors which effect on the prognoses of the patients of early death and the long survivors after the recurrence of the disease.
