Aim:
To investigate the correlation between breast cancer in Greek women and ABO blood groups.
Material-Methods:
In 166 female patients with breast cancer factors such as blood group, histological type, family history, presence or absence of nodal and/or distant metastases were examined. These patients had similar demographic, clinical, surgical, immunohistochemical, laboratory, and follow-up data and this group is representative of general population of women in Greece.
Results:
The ductal type of breast cancer was differentially distributed in blood groups Rh (+) (P
Conclusion:
Blood group A is often associated with ductal breast cancer (49.6%), in contrast to the other blood groups and particularly to blood group AB (3.6%). Blood group A and, particularly, A (-) has the worst prognosis of all.
