Reactive carbonyl compounds of protein in patients’ blood after surgical treatment of
breast cancer

Introduction.
The problem of breast cancer (BC) is one of the important and complicated in oncology. In this
aspect, there is a significant amount of interest in the study of oxidative processes, since their disorders can act
as one of the pathogenetic factors of carcinogenesis.
Aimof the study:
To study the Reactive carbonyl compounds of proteins (RCCs) in plasma and in erythrocytes
of blood of the BC patients after surgical treatment.
Materials andmethods:
The blood of 20 women with BC was examined, which have I-IIIa stages after surgical
treatment in the volume of radical resection or radical mastectomy performed at the first stage of treatment.
The control group consisted of practically healthy women (n = 15). The level RCCs in erythrocytes and in
blood plasma was determined by the method of Levine R.L et al. (1990).
Resultsof the study:
In erythrocytes of BC patients with I stage, there was a slight decrease in the percentage
of RCCs. At the same time, an increase of RCCs was observed in II stage BC patients (by 50% compared to
control, p <0.05). The level of RCCs in erythrocytes of BC patient’s blood with III stage was 2 times lower than
the control. In blood plasma of BC patients with I stage the significant increase in RCCs was observed (3 times
compared with the control). In BC patients with II stage, this indicator exceeded control by 70-75% (p <0.05),
whereas in patients with III stage of BC, the content of RCCs did not differ significantly from control.
Conclusions:
These data suggest the development of carbonyl stress in the body of BC patients. Surgical
removal of the tumor in breast cancer does not eliminate the conditions for the oxidative modification of
proteins.
