Microbiome Program
The study of the microbes (bacteria, fungi, viruses) that inhabit the human body, including the gastrointestinal (GI) tract, and how they affect health and disease is a rapidly emerging field with significant scientific and clinical potential. Research on the microbiome deepens our understanding of cancer and promotes innovative methods for its prevention, diagnosis and treatment.
The Microbiome Program at City of Hope® is revolutionizing cancer care through a nexus of personalized and holistic medicine, integrating diet, nutrition and the immune system to promote early detection, personalized interventions and better treatment outcomes. The microbiome plays a significant role in cancer progression and immune responses, which can impact the effectiveness of chemotherapy, immunotherapy, radiotherapy, surgical and targeted therapies. It can also help predict treatment responses and enhance the efficacy of existing therapies.
Mission and Vision
Founded in 2024 under the leadership of Robert Jenq, M.D., the Microbiome Program is dedicated to revolutionizing cancer care by harnessing the untapped therapeutic potential of the microbiome. Through state-of-the-art science and innovation, City of Hope strives to establish itself as a global hub for microbiome research, developing breakthroughs that enhance cancer treatment outcomes worldwide.
