RÉSUMÉ
Background: Breast cancer tops the global cancer incidence rates, having the highest rate of death among women. The primary objective of this study was to assess the impact of standard chemotherapy treatment dose adjusted for the Sri Lankan population, on hepatic and kidney function of breast cancer patients. Methods: The study conducted a cross-sectional, retrospective and prospective analysis of 75 breast cancer patients who received doxorubicin, cyclophosphamide, and paclitaxel chemotherapy regimen with normal liver and renal function at baseline at UHKDU oncology clinic. The study population had a mean age and BMI of 54.04±11.33 years and 26.7±3.89, respectively. Prior to starting the 16-cycle chemotherapy treatment, mean serum SGOT, SGPT, Creatinine, and eGFR values were 27.57 U/l, 31.32 U/l, 0.71 mg/dl, and 99.07 ml/minute/1.73 m2 respectively. Results: During the treatment, there was a statistically significant increase in the mean values of SGOT and SGPT (p<0.05), whereas there was no significant variation in the mean values of creatinine and eGFR (p>0.05) compared to the baseline results. The study identified a significant positive correlation in SGOT (r=0.793) and SGPT (r=0.872) values, while there was a noteworthy negative correlation (r=-0.757) between eGFR and chemotherapy cycle. Furthermore, there was a positive significant correlation between serum creatinine levels and chemotherapy cycle (r=0.579). Conclusions: The dosed adjusted chemotherapy regimen had a significant impact on hepatic function but had no statistically significant impact on renal function among the study population. Further research is recommended to evaluate the long-term effects of standard chemotherapy treatment on liver and kidney functions.
