Correlation between anxiety parameters and oestrogen receptor levels (ER) were investigated in 89 patients with primary breast cancer. Patients were divided into two groups, ER poor (< 0.05 fmol/microgram DNA) and ER rich (> 0.05 fmol/microgram DNA). No differences were found between anxiety levels, determined by a modified Hospital Anxiety and Depression (HAD) scale, in the two groups. This report does not support the findings from other studies, claiming an association between psychological parameters and oestrogen receptor status, which is believed to be a prognostic predictor.
