Operable breast cancer patients with diagnostic delay--oncological and emotional characteristics

Delayed diagnosis in cancer patients often implies presentation with advanced disease with poorer prognosis as a consequence. The aim of the present study was to gain more insight into mechanisms which determine patient delay in the diagnosis of operable breast cancer, stages I and II.

Patient delay was related to socio-demographic, psychological and clinical-oncological variables in 96 consecutive patients investigated one day before surgery.

Patients with a diagnostic delay for one month or more (N=29) reported increased emotional control compared to patients without delay (N=67) (Mean score on Courtauld Emotional Control scale (CEC) 54.5 vs 46.4; p=0.003) and more often grade I tumour (17 out of 29 vs 16 out of 67 patients; p=0.002). Diagnostic delay was predicted independently by tumour differentiation (hazard ratio=5.0; p<0.01 (95% CI: 1.7-14.8)) and emotional control (hazard ratio=5.1; p<0.01 (95% CI: 1.6-16.1)). Multivariate survival analysis with tumour grading and patient delay as covariates showed significant survival effect for tumour differentiation only (hazard ratio=4.4; p<0.05 (95% CI: 1.3-15.4)).

There seems to be an association between aggressiveness of tumour growth, diagnostic delay and emotional control in patients with early stage breast cancer. Clinical implications of these findings are discussed.
