Cancer patients face a new threat in the form of antimicrobial resistance (AMR), according to recent studies published by the Cancer AMR Consortium. These studies have revealed that infections, often caused by drug-resistant bacteria, are the second leading cause of death in cancer patients. Hospitalized cancer patients are also more likely to have infections caused by resistant bacteria compared to non-cancer patients.
The impact of AMR on cancer care has not been widely acknowledged by leading cancer organizations and conferences. Many deaths attributed to cancer may actually be caused by drug-resistant infections, highlighting the need for better recognition and understanding of this issue.
Oncologists emphasize the urgent need for better diagnostics to quickly identify infections, determine drug resistance, and choose effective medications. The current delay in identifying antibiotic resistance can lead to incorrect treatment decisions, putting patients at risk. Additionally, there is a critical need for new antibiotics to combat the rising rates of resistance. The lack of innovation in antibiotic development is attributed to a lack of commercial incentives for drug developers.
Innovative approaches such as subscription models, where national health services pay a fee for access to new antimicrobial drugs, are being explored to incentivize antibiotic development. However, more ideas and incentives are needed to address the growing threat of AMR in cancer care.
Failure to address antimicrobial resistance could have dire consequences, limiting the ability to safely administer life-saving cancer treatments such as CAR T-cell therapy. Without a replenished pipeline of antibiotics, doctors may face challenges in providing adequate care to patients, particularly in low and middle-income countries where access to antibiotics and infection control measures are limited.
Policymakers must take action to reform incentives for antibiotic-resistant medications to encourage investment in new drug development. The stakes are high for cancer patients and others affected by AMR, underscoring the importance of finding solutions to this pressing public health issue.
