Changes of the total antioxidative status of blood cells in the progression of stomach and large bowel cancers in patients subjected to primary radical treatment

摘要

The analysis included 53 patients (32 men and 21 women) aged 43 to 66 years, who were subjected to radical treatment (surgical or combined) because of stomach (22 patients) or large bowel (31 patients) cancer. All the patients were included in the same model of control examinations, which considered evaluation of the erythrocytes TAS and of the Ca19-9, CEA and AFP concentrations in serum. It was confirmed that in all the patients in whom the recurrence and/or the dissemination occurred of the cancer, the average erythrocytes TAS value increased 5.5 times by comparison with the period before progression and 7 times in comparison with the patients without recurrence and/or dissemination of the cancer. Moreover it was shown that statistically significantly higher TAS values were associated with the progression of the large bowel cancer in comparison with the stomach cancer and that the blood cells TAS positively correlated with the changes of the Ca19-9, CEA and AFP concentrations in patients with progression of the cancer after radical treatment.
