Abstract

It is of interest to evaluate the influence of breast cancer on oxidative stress, liver function tests, renal biomarkers, action of doxorubicin, cyclophosphamide and paclitaxel (AC-T) in the treatment and mechanism over altering the measured markers in breast cancer. Sixty histopathological confirmed cases of female patients suffering with breast carcinoma from the Department of Oncology at Omega Cancer Hospital, Visakhapatnam were included in the study. The investigation was performed in 3 groups: a control group containing 30 healthy females of similar age, 30 breast cancer patients without treatment and 30 patients receiving treatment with anticancer combination drugs AC-T. The venous blood samples from both controls and patients were measured for total antioxidant status (TAS), nitric oxide (NO), malondialdehyde, alanine aminotransferase, aspartate aminotransferase, and blood urea, serum creatinine. One-way ANOVA and Tukey-Kramer multiple comparisons post-test were applied as statistical analysis tools through SPPS software version 20.0. P<0.05 was regarded as significant. According to the findings, higher stages of breast cancer were linked to considerable increase in oxidative stress markers during AC-T treatment. The findings of the study revealed that oxidative stress is linked to breast cancer, and that chemotherapy exacerbates this oxidative stress, causing damage to a variety of cellular _targets. Monitoring serum oxidative stress markers may aid in the evaluation of chemotherapy effects in breast cancer patients. According to our findings, AC-T chemotherapy will elevate malondialdehyde, a lipid peroxidation marker, and lowers the total antioxidant status.

Keywords: Breast cancer; chemotherapy; malondialdehyde; oxidative stress; total antioxidant status.
