Abstract
Patients with solid tumors present a higher risk of infectious diseases with worse outcomes compared with immunocompetent patients. Prolonged treatment of prophylactic and empirically chosen antibiotics and health care-acquired infections can predispose patients with cancer to infections with antimicrobial-resistant (AMR) organisms. AMR is a global health priority and can affect patients with cancer. The outcome of patients with cancer worsens dramatically if multidrug-resistant (MDR) microorganisms cause infections. Moreover, the emergence of MDR organisms increases health care costs. Antimicrobial stewardship programs can be useful to monitor and improve the use of antibiotics in all oncological settings, including the palliative setting. Awareness of the magnitude of these issues is still low, so it is important to inform and educate oncologists. This narrative review aims to illustrate the main evidence on infections caused by AMR organisms in patients with cancer and the tools that oncologists should have to enhance their multidisciplinary management.
