Univariate analysis for disease recurrence and survival
The significance of stage, histology, differentiation,
menopausal status, age, ER, PR and Her2/neu status,
adjuvant therapy and CTC for RFS and BRD is shown
in Table 1. T-stage, N-stage, overall stage, differential
grade, ER status, PR status, Her2neu status and CTC
were significant for RFS and BRD. For CTC a cutoff
value of 1 or more CTC was chosen. If similar analyses
are performed with higher cutoff values than CTC is no
longer significant. This is probably due to the small
number of patients that had 2 or more CTC.
