SUMMARY
(1) Introduction to the lecture
Norie KAWAHARA began by reiterating the overall theme for the autumn 2025 lecture series: Beyond Borders: Navigating Health Knowledge for Well-Being. She noted that in the first two sessions students had looked at Asia’s health challenges from a broad, global view. In the first class, discussions had focused on the values behind cross-border medical cooperation. In the second class, students explored the structural issue of knowledge gaps and built the foundation for our theoretical framework. The third and fourth sessions have moved on from theory to practice. In the third class, students focused on non-communicable diseases (NCDs), as a case study of urgent global concern, which had helped to connect ideas to real actions.
Dr. Kawahara noted that today’s lecture would take a new angle: looking at how generative AI, a new and powerful technology, can be used to address antimicrobial resistance (AMR), a serious global threat that affects cancer care and public health worldwide. She noted that the session brings together two important perspectives under one shared theme, namely “No One Left Behind in Cancer Care.” First, student would hear from the Union for International Cancer Control (UICC) about the global challenge of antimicrobial resistance and how it impacts cancer treatment outcomes worldwide. Second, Mr. Teppei Sakano from the Asia Cancer Forum, would show how digital transformation, from AI screening to telemedicine, can bring care closer to those who are often beyond the reach of hospitals.
By connecting these two perspectives — global health and digital innovation — it is hoped that students will be empowered to explore how Japan and Asia can work together to close the gaps in access to safe, effective, and equitable cancer care.
(2) Lecture 1
The negative impact of AMR on cancer care and treatment outcomes
Shalini Jayasekar ZÜRN presented on antimicrobial resistance (AMR) and its impact on cancer care and treatment outcomes. She began by noting that while AMR is recognized by the WHO as one of the top ten global health threats, there has been very little discussion within the cancer community about what AMR means for cancer patients and cancer treatment.
The Importance of Addressing Antimicrobial Resistance (AMR)
Antimicrobial medicines are the cornerstone of modern medicine, but AMR has become a major global health crisis requiring urgent and coordinated action. According to WHO data from 2023, one in six common bacterial infections worldwide was resistant to antibiotics. Without proper action to address AMR, life expectancy globally will be reduced by 1.8 years over the next decade. Bacterial AMR was directly responsible for approximately 1.27 million deaths in 2019 and contributed to about 5 million deaths overall. The economic impact is also significant: direct healthcare costs are estimated at up to 20 billion US dollars annually in the USA and about 1.5 billion euros in the EU. AMR is one of the greatest threats to modern medicine, but there is very little discussion so far of what it means specifically for cancer care.
The Impact of AMR on Cancer Care
As many as one in five cancer patients undergoing treatment need antibiotics. More broadly, antimicrobial medicines—including antifungals and antivirals—are important for cancer treatment. Infection is the second leading cause of death in cancer patients, after cancer itself. An analysis of more than 1.5 million bacterial isolates found that rates of AMR among priority pathogens were up to three times higher in cancer patients compared with non-cancer patients.
Cancer patients are more susceptible to infections for several reasons. The underlying disease itself compromises their immune system, and cancer treatments—including bone marrow transplants, radiotherapy, chemotherapy, and newer immunotherapies—further reduce immune function. Additionally, catheters and other medical devices used in chemotherapy and supportive care create pathways for infection, particularly when contaminated. Pneumonia and sepsis are among the most frequent causes of admission to intensive care units for cancer patients. The consequence is that some individuals with cancer that might otherwise be successfully treated are dying due to drug-resistant infections. This problem occurs more often than generally recognized, as the cancer and infectious disease communities often work in silos and do not consider cancer patients and infectious disease patients as the same population.
Global Research Findings
In 2020, UICC convened a task force of experts to guide a program on AMR and cancer care. These experts identified a gap in data on the global prevalence of AMR in cancer patients, particularly those with hematological malignancies. This led to a scoping review published in Lancet Oncology in May 2025, which aimed to estimate the global prevalence of AMR in blood tumors, determine healthcare outcomes associated with AMR, and describe key gaps and future research directions.
The scoping review analyzed 274 studies conducted in 52 countries between 2000 and 2023 (Figure 1).
Figure. 1 Overview of the scoping review of the Task Force on AMR and Cancer Care
The geographic distribution of research revealed significant disparities: 61% of studies were from high-income countries, 14% from lower-middle-income countries, and less than 1% from low-income countries. This geographic imbalance represents a notable gap in data collection across regions. Publication trends showed an increase from five papers in 2000 to 24 papers in 2024, indicating growing attention to the topic. However, the majority of studies (about 65%) were retrospective cohort studies, indicating a need for more randomized controlled trials, particularly in low and middle-income countries.
The scoping review focused on WHO priority pathogens, where resistance is increasing but few new medicines are in the pipeline. Among patients with blood tumors, the overall AMR prevalence was 35%. Bloodstream infections were the most common infection type. The top AMR pathogens were third-generation cephalosporin-resistant Enterobacterales at 44%, methicillin-resistant Staphylococcus aureus (MRSA) at 43%, and vancomycin-resistant enterococci (VRE) at 41%. Of 81 studies reporting on mortality, 65% showed that higher mortality rates were associated with AMR infections.
A second study, also published in Lancet Oncology in May 2025, compared the incidence and prevalence of AMR in outpatients with and without cancer. This study analyzed 1.6 million bacterial isolates and was conducted by the Cancer and AMR Consortium, of which UICC is part. The study found that cancer patients face AMR-resistant infections at rates up to three times higher than those without cancer. This applied to WHO priority pathogens including vancomycin-resistant enterococci and multidrug-resistant Pseudomonas aeruginosa. For specific pathogens, the incidence rate ratios showed cancer patients had roughly twice the rate of certain resistant bacteria compared to non-cancer patients. The conclusions emphasized that AMR prevalence is significantly higher in cancer outpatients, with increased AMR across multiple sources of infection including blood, respiratory, urinary, skin, and wound sources.
The Burden of AMR on Cancer Outcomes in Low and Middle-Income Countries
Data on the situation in low and middle-income countries remains limited compared to high-income countries. However, anecdotal evidence from UICC members in low and middle-income countries indicates that AMR is a significant issue. Some members have reported using Colistin, a reserve medicine on the WHO classification, due to lack of access to appropriate medicines. Hospital-based surveillance studies in various countries show evidence of drug resistance.
For example, one study in India showed that about 73% of patients with blood cancers were colonized with carbapenem-resistant bacteria in the gut. In Ghana, 45% of bacteria causing bloodstream infections in cancer patients were multidrug-resistant. A 2017 study in Ethiopia showed that bacterial infections in cancer patients were present in approximately 20% of cases, with multidrug resistance common. In Uganda, 85% of a certain class of bacteria (Enterobacteriaceae) causing bloodstream infections in cancer patients were multidrug-resistant. Although the data on a global scale is limited, these hospital-based surveillance studies demonstrate that the problem exists and action is needed.
UICC's Program of Work on Raising Awareness of AMR
AMR became a priority for UICC in 2020, at a time when awareness of AMR within the cancer community was minimal. UICC convened an expert task force including members from both the cancer community and infectious diseases community, with representation from organizations including the Norwegian Cancer Society, Swedish Cancer Society, and WHO. The program of work on AMR and cancer is guided by three policy asks: data collection and surveillance to inform policy; access to treatment through infection prevention and control, antimicrobial stewardship, and availability of quality-assured medicines and diagnostics; and emphasis on the importance of AMR alongside cancer treatment through streamlining of international policy documents and integration into national cancer control plans.
To raise awareness and mobilize change, UICC has developed several resources. These include a master course on the impact of AMR on cancer care outcomes covering why the cancer community should address this issue, the need to merge cancer registries with microbiology data, and relevant guidelines. The AMR Control supplement, written by 50 experts, provides recommendations for policy engagement. UICC also developed virtual dialogues, webinars, and policy briefs for the cancer community and cancer health workforce. Sessions were held at the World Cancer Leaders’ Summit and World Cancer Congress to engage world leaders. Side events occurred at the World Health Assembly and multi-stakeholder dialogue on AMR in New York. An important advocacy achievement was the inclusion of text on AMR and cancer in the United Nations Political Declaration on AMR in September 2024 and the Political Declaration on Noncommunicable Diseases in September 2025.
Integrating AMR into National Cancer Control Plans (NCCPs)
A current focus for UICC is including AMR mitigation strategies in national cancer control plans (NCCPs). A review of NCCPs found that only two countries explicitly mentioned AMR: Turkey included reference to antibiotic use for Helicobacter pylori, and Zambia highlighted antibiotics alongside essential cancer medicines and referenced WHO guidance on antibiotic use and surveillance. Malta and Moldova included text on infection control and prevention. Only four NCCPs globally currently include AMR considerations, though some Nordic countries are moving toward including AMR in their cancer strategies.
To support cancer planners, the International Cancer Controller Portal recently launched a new thematic page exploring the link between AMR and cancer, listing resources for planners to use when including AMR in national cancer control plans. A policy brief encourages cancer planners to focus on five areas as a starting point: surveillance and data collection through strengthening diagnostic and microbiology lab capacity; infection prevention and control through developing programs using WHO guidance; effective antimicrobial stewardship; access to quality antimicrobials and diagnostics; and funding and implementation (Figure 2).
Figure. 2 Overview of measures to integrate AMR strategies into NCCPs
UICC will continue working with members and task force experts to push for including AMR in national cancer control policies, viewing this integration as a critical first step toward implementation.
Conclusion
In conclusion, Dr. Zürn noted that AMR presents a growing challenge, particularly for cancer patients. Research shows that cancer patients have significantly higher rates of resistant infections and worse outcomes when these infections occur. However, data gaps remain, especially in low and middle-income countries. The cancer community and infectious diseases community need to work together through targeted interventions and global collaboration. If appropriate action is not taken, all gains in cancer control and modern medicine will be at risk, as antibiotics and other antimicrobials are essential to cancer treatment. Addressing AMR in cancer care requires integrating it into national cancer control plans, collecting data on resistant infections in cancer patients, ensuring infection prevention and control measures are in place, implementing antimicrobial stewardship programs, and providing access to appropriate medicines and diagnostics.
(3) Lecture 2
No-one Left Behind – AMR and AI: Medical DX Projects of the Asia Cancer Forum
Teppei SAKANO, Director of Digital Transformation at the Asia Cancer Forum (ACF), presented on how digital transformation and artificial intelligence can support the global response to antimicrobial resistance (AMR). He focused on how digital infrastructure and AI-based tools can connect frontline clinicians, researchers, and policy makers to address AMR in cancer care.
Digital Infrastructure and Telemedicine Applications
ACF has been building medical digital transformation (DX) projects that integrate medical data platforms, telemedicine systems, and AI-based diagnostic imaging tools. Telemedicine operates in two primary models: doctor-to-patient, where physicians provide care directly to patients through smartphones and apps, and doctor-to-doctor, where expert oncologists support local physicians remotely.
ACF has developed mobile-based applications allowing clinicians to share images and support each other in real time, with these platforms also used for training and live mentoring through remote connections to surgical rooms.
Telemedicine systems are increasingly integrated with medical devices. A portable ultrasound system with AI can automatically screen patients and alert physicians to abnormalities, with expert support available via teleconsultation for complex cases. Similar structures apply to portable x-ray systems and AI-assisted mammography units operating from mobile units. These solutions have been deployed in various locations, including temporary medical examination sites at elementary schools in Brazil, particularly in areas with extremely low accessibility such as the Amazon region. The technology enables rapid deployment even in disaster or conflict zones, bridging gaps between large hospitals and rural clinics.
Oncology Networks and Humanitarian Applications
A major initiative is a doctor-to-doctor network for oncology developed in collaboration with the National Cancer Center of Japan, where oncology specialists provide teleconsultation to local physicians for difficult cancer cases. This infrastructure has been adapted internationally for infection control and AMR monitoring as well.
Since 2022, ACF has collaborated with Ukrainian medical authorities to address digital health capacity in conflict-affected regions. Over 1,600 medical facilities have been damaged or destroyed during the war. The ACF team has been installing portable diagnostic equipment with AI screening capabilities and telemedicine connections to Japanese hospitals to support affected areas.
Education is another critical component, with tele-education and observer programs established to train Ukrainian medical professionals. Sixteen medical doctors from Ukraine completed two-month training programs in collaboration with Japanese hospitals and national centers. Through these efforts, the organization identified that AMR has emerged as a significant issue in Ukraine, affecting hospital operations, patient outcomes, and national health resilience. The presence of multidrug-resistant infections is high among trauma and cancer patients, combined with limited access to diagnostics and appropriate antibiotics.
AI-powered Infection Control Platform
ACF has launched an AMR digital transformation project in collaboration with the Japanese government's infection control centers, WHO, and Ukrainian partners. The system is an AI-powered platform that collects, analyzes, and visualizes data on antimicrobial use and resistance trends. Users can input patient data, diagnosis information, and pathogen data to receive AI-generated antimicrobial recommendations. The system connects with laboratories to monitor resistance patterns, provides clinical insights and feedback, and includes access to current infectious disease research and news. Real-time dashboards display facility and regional-level resistance statistics for health facilities and public health authorities.
The project integrates infection control data collection with AI-driven diagnostics and optimal antibiotic recommendations. It has been implemented in Ukraine in collaboration with government public health centers and hospitals. The system is provided free of charge to clinicians, hospitals, and pharmaceutical companies developing new antibiotics. The overarching concept is to ensure no one is left behind in the global fight against AMR through AI and medical digital transformation.
(4) Discussion
Dr. Iwasaki, moderator of the discussion session, opened by asking Dr. Zürn to clarify the definition of AMR for a diverse audience including non-medical students.
Dr. Zürn explained that AMR stands for antimicrobial resistance and encompasses all medicines used to treat infections, including antibiotics, antifungals, antivirals, and antiparasitics. She noted that the public may better understand the terms 'drug resistance' or 'superbugs.' AMR occurs when medicines taken to fight infection no longer work. While resistance exists across all therapeutic areas, its acceleration is driven by inappropriate and overuse of medicines, such as doctors prescribing antibiotics for viral infections or using antimicrobials as growth hormones in agriculture and livestock. She emphasized that the research and development pipeline for new antibiotics and antifungals is not advancing at the pace needed, particularly compared to blockbuster cancer treatments.
Dr. Iwasaki characterized AMR as a worldwide crisis, sometimes called a 'silent pandemic' with potential to cause greater health impacts than COVID-19. He noted that AMR is a threat to all countries globally. He emphasized that currently there are no effective therapeutic options for treating AMR infections, creating a significant challenge for physicians managing affected patients. Cancer patients are particularly vulnerable because they face both the underlying disease and treatment-related immunosuppression, making them fragile and susceptible to infection.
Dr. Iwasaki asked how AMR infections should be properly managed. Dr. Zürn explained that guidelines vary by region. When cancer patients develop fever with neutropenia, initial standard treatment is monotherapy. However, once an AMR pathogen is identified, management becomes more complex, potentially requiring admission to intensive care and more complicated intravenous formulations. She stressed that empirical treatment must be adapted to local surveillance data, including antibiogram information, and that guidelines must be facility-specific, current, and based on surveillance data. She noted that guidelines from the American Society for Clinical Oncology (ASCO) and Infectious Diseases Society of America (IDSA) from 2018 are outdated. The main message is that guidelines must be updated and the cancer and infectious diseases communities must collaborate at national and facility levels to ensure antimicrobial stewardship alongside cancer treatment.
Dr. Iwasaki described Japanese hospital practice, which typically involves isolating infected patients and selecting appropriate antibiotics for AMR pathogens. He noted that many cases are complicated with mixed infections, so proper antibiotic use is essential. He acknowledged that while guidelines exist, they require updating for current situations. He emphasized that proper information and correct understanding are critical for doctors and nurses. He suggested that Mr. Sakano’s application tool could be valuable for showing infection prevalence status and proper treatment approaches.
Mr. Sakano explained that his team is focusing on Ukraine as an AMR epicenter. The CDC has announced that AMR is spreading from Ukraine to the rest of the world. A critical issue is that wounded soldiers take seven to ten days to transfer from the frontline to hospitals, and then are transferred to neighboring countries like Poland, Romania, Germany, and Switzerland, spreading AMR during these transfers. During transfer, patients acquire many pathogens, but medical data including testing results and antibiotic usage information are not shared between clinicians. This data sharing failure is a major problem. Additionally, clinicians use multiple antibiotics to prevent patient death, but without knowing what medications were previously prescribed, the usage multiplies and escalates. Studies indicate that trauma patients have a 50% higher mortality probability due to AMR issues in Ukraine.
Dr. Iwasaki noted that soldiers and cancer patients share common features: both are in poor situations for infection control and are physiologically weak. He observed that Mr. Sakano's system serves two purposes: accumulating correct information about infections and current AMR infection status, and providing doctors and medical personnel with proper guidance on using antimicrobial drugs and infection control methods. He stated that such systems are needed not only in Ukraine but also in other countries, including Japan and developed nations, which currently lack nationwide or region-wide capability to capture AMR infection status. He emphasized that new drug development is difficult from a business perspective and requires national, government, and global support.
Mr. Sakano highlighted the dramatic decline in antibiotic development. In Japan during the 1990s, 27 new antibiotics were approved; from 2010 to 2020, only three were approved—approximately one-tenth the previous rate. In the United States, antibiotics comprised 20% of all new drug pipelines in the past; now only 6% are antibiotics. Pharmaceutical companies are reluctant to develop new antibiotics, with only 3,000 scientists globally now working on this compared to 50,000 previously. His focus is to demonstrate to pharmaceutical companies how proper antibiotic usage through data systems can extend product lifetimes and generate profit, potentially encouraging pharmaceutical development. By targeting and limiting antibiotic usage, revenue can be maintained while preserving drug effectiveness.
Dr. Zürn noted that Mr. Sakano’s application tool could be amazing if implemented, but noted challenges in linking laboratory data and cancer registries, particularly in low and middle-income countries (LMICs). She emphasized that these challenges should not prevent attempts. The first step is bringing cancer and AMR communities together to recognize the importance of merging data.
A student asked what policy changes LMICs could adopt to ensure responsible antibiotic use among practitioners, given challenges of poor lifestyles, limited resources, and easy availability and overuse of antibiotics. Dr. Zürn emphasized patient awareness of what AMR is, AMR risks, and infection prevention and control. For practitioners, she recommended guidelines based on local, up-to-date surveillance data for infections in cancer wards and facilities. Guidelines should be harmonized at national and local levels with microbiological support. She stressed that cancer and infectious disease departments should coordinate when procuring antimicrobials alongside cancer medicines, using the WHO model list of essential medicines as guidance but adapted to local needs.
A student noted that antibiotic usage is higher in animal medicine than human medicine but questioned why the focus is on human medicine when most emerging infections have zoonotic origins. Dr. Zürn acknowledged the issue and explained the recent Quadripartite Agreement that brings agriculture, environment, human, and veterinary sectors together to address AMR collaboratively through a One Health approach. Antibiotics are misused in animals as growth hormones due to lack of education. The FAO and World Animal Health Organization have guidelines and standards, though education remains needed in resource-limited settings.
Dr. Iwasaki added that huge volumes of antibiotics are used in agriculture and animal feeding, and attention must focus on non-medical fields alongside medical applications when considering total antibiotic consumption and its role in creating AMR pathogens.
A student asked whether standards exist for antibiotic use in animals. Dr. Zürn stated that guidelines exist from the FAO and World Animal Health Organization, but education is lacking in resource-limited settings. For humans, the WHO has the AWaRe (access, watch reserve) classification and WHO model list of essential medicines guidance. However, global guidance must be adapted at national, regional, and facility levels based on local surveillance data.
A student asked about AI progress in addressing challenges of multidrug-resistant microbes, including discovering new antibiotics. Mr. Sakano explained that the application imports surveillance data from WHO and governments plus clinical data and published papers. AI instantly updates with changes, which humans cannot do as quickly. However, accuracy and phantom data results must be continuously checked. The team uses new AI models from ChatGPT, Gemini, and Claude, etc., recognizing clear advantages in using modern AI.
Dr. Iwasaki added that AI is widely used in drug development beyond infectious diseases, helping identify proper targets and supporting multiple phases of drug development, with pharmaceutical companies increasingly utilizing AI tools. He expressed hope that AI could help develop drugs for AMR pathogens.
A student asked how low-income countries should proceed with publishing national guidelines when lacking evidence from clinical research and funding. Dr. Zürn advocated for increased randomized controlled trials in low and middle-income countries, acknowledging challenges but emphasizing need for data. She recommended using the WHO Model List of Essential Medicines as a model but adapting it to country-specific needs through national committees. She mentioned CDC Africa has guidelines on AMR and cancer. Most importantly, she urged that national cancer control plans include infection management, infection prevention and control, and procurement of appropriate antimicrobials and diagnostics.
Dr. Iwasaki noted that collaboration between oncologists and infectious disease specialists is essential, and cited the National Cancer Center of Japan's decision decades ago to establish an infectious disease control department as recognition of this importance.
5) Assignment
Students were given the following assignment:
