title: ABO blood groups and bladder carcinoma.
abstract: Following some reports concerning the possible influence of ABO blood groups on constitutional types and different features of human pathology, we have investigated if there are relationships between ABO blood groups and bladder tumors. Our findings show that tumoral behavior in patients with bladder carcinoma and blood group O has a tendency to an increased aggressivity with higher tumoral grade and more relapses than what is seen in tumors of patients with A blood group. Although this difference is not statistically significant, we believe that blood group ABO should be considered as a constitutional prognostic factor in bladder carcinoma and further investigations in this field are needed.
