Cancer Patients Face Elevated Risk of Carrying Antimicrobial Resistant 'Superbugs'

Rhea-AI Summary

New groundbreaking studies published in The Lancet Oncology and Cancer Medicine reveal that cancer patients face significantly higher risks of developing antimicrobial resistant (AMR) infections compared to non-cancer patients. The research, conducted by the Cancer and AMR Consortium including BD (NYSE: BDX), analyzed over 1.6 million bacterial isolates from 198 outpatient facilities and 4.6 million hospital admissions in the U.S. Key findings show AMR rates were 1-3 times higher in cancer patients, with some specific pathogen combinations up to 5 times greater in outpatient settings. For hospitalized cancer patients, the risk was 1.5-2 times higher. The studies highlight critical concerns about AMR's impact on cancer treatment effectiveness, particularly for innovative therapies like CAR T-cell therapy, and emphasize the need for enhanced infection prevention programs and diagnostic tools.

Positive

• BD's involvement in groundbreaking research strengthens its position in diagnostic and infection prevention markets
• Study findings could drive increased demand for BD's rapid diagnostic tools and infection prevention solutions
• Research collaboration with prestigious organizations (UICC, AMR Action Fund) demonstrates BD's leadership in healthcare

Negative

• Rising AMR rates could impact the effectiveness of cancer treatments, potentially affecting related medical product demand
• Increased focus on infection prevention may require additional R&D investment from BD
• Growing AMR threat could lead to stricter regulations and protocols in medical settings

FRANKLIN LAKES, N.J., May 21, 2025 /PRNewswire/ -- First-of-their-kind studies published in The Lancet Oncology¹ and Cancer Medicine² provide new data showing that cancer patients in both hospital and outpatient settings are at a substantially higher risk of developing antimicrobial resistant (AMR) infections compared to all other non-cancer patients.

Key Takeaways:

• The studies, led by the Cancer and AMR Consortium, which includes BD (Becton, Dickinson and Company) (NYSE: BDX), the Union for International Cancer Control (UICC), and the AMR Action Fund, found AMR rates among key pathogens were 1 to 3 times higher, and up to 5 times greater with some specific pathogen-source combinations in outpatient cancer patients;³ and 1.5 to 2 times more likely in hospitalized cancer patients as compared to non-cancer patients2.
• Studies examined data on more than 1.6 million bacterial isolates collected from 198 outpatient facilities in the U.S. and more than 4.6 million admissions across 168 U.S. hospitals.

Together, the two studies, which are understood to be the first large, multi-center studies to quantify AMR among cancer patients in the U.S., offer some of the strongest evidence to date that superbugs pose a substantial risk to cancer patients across a variety of settings. 

"As an oncologist, my ability to effectively treat a patient's cancer is predicated on the idea that antibiotics will both cure and prevent potentially fatal infections throughout their course of care," said study co-author Yehoda Martei, MD, University of Pennsylvania. "The rapid emergence of AMR among oncology patients will affect cancer care, including the possibility of undermining new innovations such as CAR T-cell therapy and other immunotherapies, given the risk of immunosuppression and opportunistic infections associated with these therapies."

The rise of AMR is rapidly diminishing the effectiveness of available antimicrobial medicines, contributing to approximately 4.7 million deaths per year.⁴ Antibiotics and other antimicrobials like antifungals play a critical role in cancer care, both as a treatment for infections and as a preventative treatment to reduce the risk of infections associated with certain medical procedures, such as surgery or chemotherapy.

"These studies highlight a critical need for enhanced infection prevention programs, focused antibiotic and diagnostic stewardship, and an increased use of rapid diagnostic tools," said corresponding author Diane Flayhart, director Global Public Health at BD. "While we expected cancer patients to be at an increased risk of superbugs, we were surprised at the high proportion of AMR pathogens compared to non-cancer patients, especially in outpatient settings. It shows just how vulnerable cancer patients are to these dangerous pathogens."
