Abstract
INTRODUCTION
Acute lymphoblastic leukemia (ALL) is caused by abnormal proliferation of blasts originated from hematopoietic lymphoid precursors. ALL constitutes 75% of pediatric leukemia cases and has an incidence of 1.28/100.000 in adults. The etiology of ALL is a still matter of debate. In some studies, ABO blood groups were shown playing a role in development of cardiovascular, oncologic, and other diseases. In this study, we aimed to investigate relationship with ALL and ABO and Rh blood groups.
METHODS
124 ALL patients treated at our center between February 2014 and April 2020 were retrospectively studied. The data of age, gender and blood group of healthy thrombocyte donors were used as the control group.
RESULTS
Although the most common blood group was A Rh+ among both males and females, we did not find a statistically significant difference between control group and ALL patients regarding ABO blood group distribution and Rh positivity. When both groups were sub-grouped according to gender, they did not differ between ABO and Rh distribution.
DISCUSSION AND CONCLUSION
There are few studies about the relationship between ALL and blood group types. Our study suggests blood group frequency might be similar among ALL patients with healthy individuals. Further studies with larger patient populations are needed.
