Drugs used in chemotherapy specifically target and kill the cancer cells during the breast cancer treatment. However, the majority of anti-cancer therapies are non-specific, which will harm the innate cells. Our research work assessed the impact of chemotherapy with adriamycin/cytoxan (AC) on the influence of antioxidant enzymes and hematopathological profiles in the diagnosis and prognosis of breast cancer treated with chemotherapy.
40 breast cancer patients treated with AC chemotherapy (Adriamycin 60 mg/m2, Cytoxan 600 mg/m2) between July 2020 and March 2021 are part of this prospective study. The first sample was taken prior to chemotherapy, the second after the intervention's three cycles, and the third after the intervention's last cycle. Spectrophotometric technique was used to evaluate the amounts of antioxidant enzymes in serum samples. Patients' demographic variables, clinical features, biochemical andhematogical parameters data were noted. The data was compared before and after treatment using the Paired-t test.
55% of the patients were detected with carcinoma on left breast and majority was in Grade 3 clinical stage 37.5%. Most of the patients express estrogen and progesterone receptors 72.5%. Our findings demonstrated that a significant decrease in the mean values of antioxidant enzymes MDA, NO, TAS, CAT, GPx, GR, SOD and GST along with hematological parameters after three cycles of AC treatment in breast carcinoma individuals. The p-value is < 0.05.
Our research demonstrates that the body's oxidant/antioxidant system, particularly reduction levels and antioxidant enzyme activity, is drastically altered by AC chemotherapy in breast carcinoma individuals.
在乳腺癌治疗中,化疗药物专门靶向并杀死癌细胞。然而,大多数抗癌疗法是非特异性的,这会损害天然细胞。我们的研究工作评估了阿霉素/环磷酰胺(AC)化疗对乳腺癌化疗患者抗氧化酶和血液病理学特征在诊断和预后方面的影响。
2020年7月至2021年3月期间接受AC化疗(阿霉素60mg/m²,环磷酰胺600mg/m²)的40例乳腺癌患者是这项前瞻性研究的一部分。第一个样本在化疗前采集,第二个在干预三个周期后采集,第三个在干预最后一个周期后采集。采用分光光度技术评估血清样本中抗氧化酶的含量。记录患者的人口统计学变量、临床特征、生化和血液学参数数据。使用配对t检验比较治疗前后的数据。
55%的患者左乳检测出癌,大多数处于3级临床分期(37.5%)。大多数患者表达雌激素和孕激素受体(72.5%)。我们的研究结果表明,乳腺癌患者在接受三个周期的AC治疗后,抗氧化酶丙二醛(MDA)、一氧化氮(NO)、总抗氧化能力(TAS)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GPx)、谷胱甘肽还原酶(GR)、超氧化物歧化酶(SOD)和谷胱甘肽S-转移酶(GST)的平均值以及血液学参数显著下降。p值<0.05。
我们的研究表明,AC化疗会使乳腺癌患者体内的氧化/抗氧化系统,特别是还原水平和抗氧化酶活性发生显著改变。
