ABSTRACT
Introduction: Breast cancer is the most common type among women and brings to them significant organic changes. A new intracranial pressure monitorization method consists of an external system of sensors that detects micrometric deformations on the cranial bones and transmits, in real-time, electrical signals that are visualized on a monitor. Objective: To identify changes in intracranial pressure due to chemotherapy connections through non-invasive methodology. Methods: The present study was conducted at Hospital Santa Casa de Misericordia in the city of Ponta Grossa, PR, Brazil in 2017. The variables P2/P1 ratio (ICP morphological evaluation), laboratory parameters, comorbidities, and clinical aspects of the volunteers were evaluated. The vascular toxicity of chemotherapy often causes endothelial dysfunction, resulting in a loss of vasodilation effects and suppresses anti-inflammatory and vascular repair functions. Results: The values of the P2/P1 ratio before and after chemotherapy were also compared between groups. A statistically significant difference was observed in the pre chemotherapy P2/P1 values compared to the post-chemotherapy values. Conclusion: Variations in ICP may occur in cancer patients. Further studies are necessary to evaluate if this change may contribute to the chemotherapy side effects occurrence.
