Abstract 50P
Background
As we enter an aging society, the number of elderly breast cancer patients is increasing. We assessed the prognostic factors of recurrence or metastasis for breast cancer patients over the age of 65 by analyzing the characteristics of tumor and long-term clinical outcomes.
Methods
Data were retrospectively analyzed for 286 breast cancer patients aged 65 years and older who underwent treatment in the Pusan national university hospital and Pusan national university Yangsan hospital from 2008 to 2014. Dividing two groups as the patients with event such as recurrence or metastasis and those who without it, the Cox regression model was used to examine the risk factors of recurrence or metastasis.
Results
Among 286 patients with invasive breast cancer, forty three patients (15.0%) have been found to have recurrence or distant metastasis during median follow-up period of 61 months. The poor prognosis was found in the advanced stage of breast cancer, patients without endocrine therapy and low Allred scores of estrogen receptor.Table: 50P
Variable | Hazard ratio | P-value | 95% CI |
---|---|---|---|
Stage | 1.78 | <0.0001 | (1.39, 2.28) |
Endocrine therapy | 0.04 | 0.0002 | (0.01, 0.23) |
Estrogen receptor | 1.34 | 0.0076 | (1.08, 1.66) |
Conclusions
The advanced stage of breast cancer was poor prognosis in the elderly breast cancer patients. Moreover, endocrine therapy should be performed on elderly breast cancer patients with high Allred score of estrogen receptor because it is good for prognosis.
