“…Firstly, univariate analyses were performed for socio-demographic characteristics including age at first diagnosis, age at recurrence, marital status, education, job, economic status and clinical variables including menstruation, time since first diagnosis, time since recurrence, performance status, chemotherapy, and recurrence pattern (data not shown). We only included variables in the multiple regression models which were determined as significant according to univariate analysis or were reported as strong predictors for QOL of recurrent breast cancer patients in previous studies [2,8,16-18].
