The median follow-up period was 60.5 months (range 9-123 months). Seventy-nine women (23.5%) had a low pre-treatment haemoglobin concentration, but anaemia was not correlated with age, tumour size, nodal status, histological grade or hormone receptor status. Univariate analysis revealed that disease-free survival and overall survival were shorter in patients with anaemia at the time of diagnosis than in patients with normal haemoglobin concentrations. Anaemia remained a significant prognostic factor for disease-free survival and overall survival in the multivariate analysis (relative risk, 1.884 and 1.785, respectively). These results suggest that pre-treatment haemoglobin concentration is an independent prognostic factor in patients with early-stage breast cancer.<\/jats:p>","DOI":"10.1177\/147323000503300307","type":"journal-article","created":{"date-parts":[[2013,2,27]],"date-time":"2013-02-27T14:22:43Z","timestamp":1361974963000},"page":"319-328","source":"Crossref","is-referenced-by-count":6,"title":["Pre-treatment
