Monoclonal Antibodies in Oncology and their Effect on Arterial Stiffness — A Systematic Review.

Introduction: Malignancies are the second leading cause of death worldwide. Treatment Monoclonal Antibody (MAbs)-based treatment of cancer has been established as one of the most successful therapeutic strategies in the last 20 years; however, there is a growing concern about the effects of these agents on patients' cardiovascular profile. Areas Covered: In this manuscript we summarize current evidence regarding MAb effects on arterial stiffness, which is an recognised biomarker of cardiovascular risk. For this purpose, we explored two bibliographic databases [PubMed, Scopus] and one full-text database (Google-Scholar) for all publications published on MAbs' effects on arterial stiffness until December 2019. Only few of the monoclonal antibody agents used in oncology have been investigated as per their effects on arterial properties and this limited evidence suggests that cancer therapy with monoclonal antibodies demonstrates either a temporary or long-term increase in arterial stiffness. Discussion: It seems that by targeting 'checkpoints' in cancer genesis, anticancer MAbs also affects vascular properties causing endothelial dysfunction and arterial stiffness. Furthermore, several MAbs cause hypertension and may as a result increase pulse wave velocity. On the other hand, MAbs that target inflammatory cytokines seem to improve cardiovascular survival however, their effect on arterial stiffness is yet to be investigated. Further research is warranted in order to elucidate the biochemical pathways, clinical implications and potential reversibility of monoclonal antibody chemotherapy-induced vascular dysfunction.
