Abstract
Main: The pharmacological treatment of cancer can lead to undesirable hemodynamic adverse effects. Laser therapy may promote hemodynamic balance in these patients. This study aimed to analyze the values of the biomarkers ultrasensitive C-reactive protein (PCR_us) and Homocysteine (HCy) after the use of intravascular laser irradiation of blood (ILIB) in mastectomized patients using hormonal blockers Tamoxifen and Aromatase Inhibitors. Methods: This was an experimental, placebo-controlled, randomized clinical trial with experimental (G1) and control (G2) groups. In G1, patients were irradiated with ILIB using a red laser at 660 nm on the carotid artery, while G2 received a placebo treatment. Blood collection for HCy and us-CRP biomarker evaluation was conducted monthly for 4 months. Statistical analysis was performed using R Studio 4.4.2 and JAMOVI, with a significance level of 5%. Results: A total of 21 patients participated in the study, with 12 in G1 and 9 in G2. There were no differences in age, systolic, diastolic blood pressure, and heart rate between the groups. The initial and final mean PCR_us levels for G1 were 6.8 and 3.8 mg/dL, and for HCy were 14.2 and 12.1 µmol/L, respectively. While for G2 initial and final mean PCR_us levels were 9.40 and 7.60 mg/dL, and for HCy were 14.33 and 16.69 µmol/L. There was no statistical difference for PCR_us. However, a significant difference between the groups (p < 0.05) for HCy in the 3rd and 4th months. Conclusion: During ILIB Therapy, there was a reduction in HCy, which may favor the improvement of cardiovascular function in these patients undergoing anticancer therapies.
