Early Dynamic Screening for Colorectal Cancer via Novel Protein Biomarkers Reflecting Biological Initiation Mechanisms. DIOPTRA seeks to revolutionize colorectal cancer (CRC) screening by offering a non-invasive, accessible, and personalized risk estimation through liquid biopsies. The aim is to identify high-risk cases that require colonoscopy, increase participation rates, and improve early detection.

Why CRC? Colorectal cancer is one of the top-3 most common cancers, with high mortality rates, metastatic potential, and detectable pre-cancerous states. Current screening participation rates are low, making it crucial to develop better methods.


  • Identify a subset of protein biomarkers for early CRC screening and understand their regulatory role through protein network analysis.
  • Conduct pilot studies at clinical sites to validate the proposed protocol and refine findings using standardized prospective data.
    Utilize state-of-the-art AI tools to detect significant biomarkers and risk factors related to CRC incidence in an objective and measurable manner.
  • Assess the effects of an extended risk factor set on CRC, offering behavioral interventions through a user-friendly mobile tool to impact modifiable pre-malignant states.
  • Advocate for change in CRC screening guidelines by providing policy makers with evidence-based data to inform decision-making on potential policy reform.
  • Investigate DIOPTRA’s expandability and network with ongoing / future cancer initiatives to empower the newly launched Knowledge Centre on Cancer, enhancing usability and accessibility for early user-friendly screening.

DIOPTRA is organized into 5 distinct phases:

  • Phase 1: Retrospective data collection, tissue / liquid biopsy samples, demographic and other relevant data, organize knowledge into standardized format, generate DIOPTRA homogenized dataset.
  • Phase 2: Risk factor investigation, initial stage of liquid biopsy biomarker analysis (early discovery), produce holistic CRC risk factor set and set of biomarker ‘hits’.
  • Phase 3: First stage of prospective data collection, acquire risk factors information and liquid / tissue biopsy pairs, analyze extended pool of samples for biomarker development, generate protein features for training and evaluating DIOPTRA AI model.
  • Phase 4: AI-based analysis for generating discriminative protein biomarkers, develop full stratification model using hybrid approach, incorporate knowledge into DIOPTRA mobile app for personalized behavioral interventions.
  • Phase 5: Clinical validation and real-settings feedback, define implementation needs for healthcare upscaling, incorporate full DIOPTRA solution into prospective studies.
