Spectral Cancer Tissue Recognition - I

Explorative, Multi-centre, Prospective, Observational Study Evaluating the Feasibility of the SPCTR Prototype for Margin Assessment During Breast Conserving Surgery in Breast Cancer Patients.

This analytical performance study aims to validate the SPCTRone system for use in breast conserving surgery of breast cancer patients. By collecting spectral biomarkers and correlating these with the golden standard of histopathological assessment by a pathologist, we aim to train and optimize an AI model that is able to achieve the following outcomes with classifying tissues:

• Sensitivity (percentage of classified positive margins of actual positive margins): ≥ 96% CI 95.5-97.5%
• Specificity (percentage of classified free margins of actual free margins): 96% CI 95.5-97.5%
• Accuracy (total correctly classified margins): ≥ 96% CI 95.5-97.5%
• Negative predictive value (amount of true negative - free margins - among the classified negative margins): ≥ 95% CI 94.5-96.5%

Inclusion Criteria:

• Age ≥18 years
• Confirmed diagnosis breast cancer for which surgical procedure is needed
• Planned for breast conserving surgery

Exclusion Criteria:

• Person that undergoes breast amputation without confirmed cancer diagnosis
