RlapsRisk™ BC

RlapsRisk® BC is an AI diagnostic to help pathologists and oncologists determine the right treatment pathway for early breast cancer patients


Product Description

Assess the risk of breast cancer relapse with RlapsRisk BC

Our research shows accurate discrimination between high and low risk of relapse*

  • Testing – suitable for adults with primary invasive breast cancer (ER+/HER2-)
  • 78% Cumulative Sensitivity – greater than those obtained by standard clinical scores*
  • Dynamic Specificity – achieves 80% specificity for post-treatment, time-dependent accuracy at 5 years*
  • Digital pathology – intended to work with surgically resected tissue on digitized slides
  • PDF report – delivered as a PDF report with user-friendly design
  • Workflow agnostic – deployment is feasible across IMS systems, or even a shared directory


Trained with data from a fruitful partnership with Gustave Roussy

Based on 1800 breast cancer patients (incl. 1480 HER2-/HR+)

Validating product performance

We work closely with medical institutions and pathology lab networks to validate our solutions and ensure their performances are robust across clinics, hospitals, and laboratories.

Image AI analysis outperforms clinical scores

RlapsRisk BC achieves 78% sensitivity and 80% specificity for post-treatment, time-dependent accuracy at 5 years, outperforming current clinical scores in practice.*

Cumulative Sensitivity/Dynamic Specificity are natural extensions of sensitivity/specificity to the setting of time-to-event outcomes, such as the metastasis-free interval (MFI), understood as the time to distant relapse occurrence from initial surgery. In use here, as they easily accommodate time-dependent outcome status as well as right-censoring.
