Abstract

ABO sustav krvnih grupa povezan je s rizikom od nekoliko malignih bolesti, ali još uvijek nije
razjašnjeno je li rizik od tumora dojke veći kod nositeljica određene ABO krvne grupe. Cilj istraživanja
bio je ispitati povezanost između genotipova ABO krvnih grupa i pojave tumora dojke te ispitati
povezanost između genotipova ABO krvnih grupa i zastupljenosti gradusa tumora (I-III) i biljega ER, PR
i HER2/neu. Istraživanjem je obuhvaćeno 59 bolesnica kojima je dijagnosticiran invazivni tumor dojke i
80 asimptomatskih, zdravih žena, dobrovoljnih darivateljica krvi. Genomska DNA izolirana je iz pune
krvi pomoću komercijalno dostupnog paketa reagensa za izolaciju: QIAampDNA Blood Mini Kit
(QIAGEN, Njemačka). Genotipizacija na pet osnovnih alela (O1, O2, A1, A2, B) i 15 genotipova bila je
izvedena pomoću PCR-SSP metode. Usporedbom genotipova i fenotipova ABO krvne grupe između
pacijentica i kontrolne skupine, dobiveno je P>0,05 te nema statističke značajnosti za povezanost ABO
genotipova/fenotipova između skupine pacijentica koje boluju od tumora dojke i kontrolne skupine.
Ispitivanjem značajnosti u razlici zastupljenosti gradusa tumora, statusa ER, PR i HER2/neu nisu
dobivene statistički značajne vrijednosti za pojavu određenog gradusa tumora te statusa biljega ER, PR i
HER2/neu u genotipu O1A1 u odnosu na ne-O1A1 genotipove ABO sustava krvnih grupa. Rezultati rada
potvrdili su da ne postoji povezanost između genotipova/fenotipova ABO krvnih grupa i tumora dojke
kod ispitivanih skupina.

Abstract (english)

ABO blood type is associated with risk for several malignancies, but still is not clear if the risk of
breast cancer is greater in carriers of certain ABO blood group. The aim of this study was to examine the
correlation between ABO blood group genotypes and the occurrence of breast cancer, as well as the
association between ABO blood group genotypes and the presence of certain tumor grades (I-III) and ER,
PR, HER2 markers. The research included 59 patients who were diagnosed with invasive breast cancer
and 80 asymptomatic, healthy women,voluntary blood donors. Genomic DNA was isolated from whole
blood using commercially available reagent packages for isolation QIAampDNA Blood Mini Kit
(QIAGEN, Germany). Genotyping of the five basic alleles (O1, O2, A1, A2, B) and 15 genotypes was
performed using PCR-SSP method. By comparing genotypes and phenotypes of ABO blood groups
between the patients and the control group, P>0,05 was obtained and there is no statistical significance for
the correlation between ABO genotypes/phenotypes of the patient group and the control group. By
examining the significance of different tumor grade occurrence, and ER, PR and HER2/neu status, it was
discovered that there is no statistical significance for the appearance of a particular grade, and tumor
markers ER status, PR and HER2 / neu status in O1A1 genotype compared to non-O1A1 genotypes of
ABO blood group system. The thesis results confirmed that there is no correlation between ABO blood
type genotypes/phenotypes and breast cancer in tested groups.
