Are risk factors for breast cancer similar in women with inflammatory breast cancer and in those with non-inflammatory breast cancer?
OBJECTIVE
The aim of the study was to compare reproductive factors in patients with inflammatory breast cancer (IBC), and with non-inflammatory breast cancer (non-IBC). The study was performed in two centers: one French including 49 IBC patients and 140 non-IBC and another Tunisian including 97 IBC and 139 non-IBC. Unconditional logistic regression was used for the analyses.


METHODS
The French IBC patients had a lower educational level, a higher body mass index and a longer cumulative duration of breast-feeding, and they included a greater proportion of non-European women, than the non-IBC patients. In the multivariate analysis, only breast-feeding duration remained associated with the IBC status (P=10(-3)). These results could not be verified in the Tunisian series, because the duration of breast-feeding was unavailable in this center.


RESULTS
This study suggests that the etiology of IBC might be different of that of non-IBC.
