BACKGROUND
Complement information about the share the role of antipapain activity in serum people with breast cancer.
OBJECTIVE
We measured the activity of cysteine peptidase inhibitors in the sera of 150 patients with breast cancer. Patients were divided into four groups depending on the cancer type and treatment method. We also analysed the control group. The activity of cysteine peptidase inhibitors was defined as a 'defensiveness' marker.
METHODS
The activity of cysteine peptidase inhibitors was measured against papain using the colorimetric method and the BANA substrate.
RESULTS
The highest activity of enzymes was found in the group of patients with BC and hereditary predisposition to it, and the lowest activity was found in patients after surgical treatment.
CONCLUSIONS
The activity of cysteine peptidase inhibitors in serum was measured against papain. We found that the activity levels were correlated with the cancer stage and treatment method. The lowest activity was found in patients after surgical treatment; the highest in women with active cancer and a hereditary predisposition to it.
