PAR-25-175: Integration of Imaging and Fluid-Based Tumor Monitoring in Cancer Therapy

Research Focus

This R01 program supports clinical studies that integrate imaging and liquid biopsy assays to monitor cancer treatment response and detect treatment resistance in real time. The NCI seeks research combining molecular or functional imaging modalities (e.g., PET, MRI) with fluid-based tumor monitoring—detection of circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), circulating RNA, or exosomes in blood, cerebrospinal fluid, saliva, or urine. Studies must demonstrate how these two modalities complement each other in characterizing therapy response across cancer types and treatment settings. Research should address questions such as: How do imaging and liquid biopsy results correlate during active treatment? What minimal biomarker changes correspond to detectable tumor changes? Can liquid biopsy monitoring substitute for routine imaging surveillance? The goal is to establish optimal assay combinations for accurate, early detection of treatment failure or resistance, informing clinical decision-making in precision oncology.

At a Glance

  • Who can apply: Domestic and foreign institutions; domestic for-profit organizations; clinical trial participation is optional.
  • Funding & project length: Less than $500,000 direct costs per year; maximum 5 years.
  • Award mechanism: R01 Research Project Grant.
  • Key dates: Open January 5, 2025; rolling due dates (next: February 5, 2025); earliest start May–July 2025 depending on cycle.
  • Best fit for: Oncology, cancer biology, medical imaging, molecular diagnostics; multidisciplinary teams integrating imaging scientists, liquid biopsy developers, and clinical researchers in first-line/recurrent disease or retrospective cohort settings.
