Cardio-Oncology Challenges in Elderly Patients

Abstract

Background and Objectives: Along with the ageing of the population, cancer and cardiovascular (CV) diseases more frequently coexist, complicating patients' management. Here, we focus on elderly oncologic patients, describing clinical features and comorbidities, discussing therapeutic management CV risk factors and CV complications risen during our CV follow-up, and exploring the different items of the comprehensive geriatric assessment (CGA) and the correlation between cardiac function by means of standard 2D echocardiography and each of the CGA items. Methods: A total of 108 consecutive patients (mean age 73.55 ± 5.43 years old; 40.7% females) referred to our cardio-oncology unit were enrolled, and three different groups were identified: Group 1, patients naïve for oncologic treatments (mean age 73.32 ± 5.40; 33% females); Group 2, patients already on antineoplastic protocols (mean age 73.46 ± 5.09; 44.1% females); and Group 3, patients who had already completed cancer treatments (mean age 74.34 ± 6.23; 55% female). The correlation between CGA, performed in a subgroup of 62 patients (57.4%), and echocardiographic parameters was assessed. Results: Group 2 patients had the highest incidence of CV events (CVEs) (61.8% vs. 14.8% in Group 1, 15% in Group 3; p ≤ 0.001) and withdrawals from oncologic treatments (8.8% vs. none in Group 1; p = 0.035). Group 2 had worse 48-month survival (47.1% vs. 22.2% in Group 1, 20% in Group 3; p = 0.05), which was even more evident when focusing on patients who died during follow-up. When assessing echocardiographic parameters, physical activity showed an inverse correlation with the left ventricular mass index (p = 0.034), while the Frailty index showed a direct correlation with the E/e' ratio (p = 0.005). Conclusions: A thorough baseline CV assessment is important in elderly oncologic patients eligible for anticancer treatment. In this population, CGA can be a simple, feasible screening tool that might help identify patients at a greater risk of developing CVEs correlating to several pivotal cardiovascular parameters.
