Comparing preoperative and pathologic tumor sizes in breast cancer

Official title: Concordance Between Preoperative Assessments and Pathologic Size Measurements in Breast Cancer: a Prospective Observational Study

Run by Incheon St.Mary's Hospital · NCT06505577 · Data updated 2026-11-12

This study is trying to see if combining different tests and factors can help doctors better plan breast cancer surgeries by predicting how much of the tumor needs to be removed.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adult patients diagnosed with invasive or in situ breast cancer who are scheduled for surgical resection.

Probably not a fit

Patients with recurrent breast cancer or those who did not undergo surgery will not benefit from this study.

What this trial studies

This observational study focuses on breast cancer patients scheduled for surgical resection, aiming to improve surgical planning by accurately predicting the extent of tumor resection. It integrates various predictive factors, including imaging studies, physical examinations, and tumor molecular subtypes, to derive a model that can guide surgeons in determining the optimal resection extent. By analyzing the interplay of these factors in real-world clinical settings, the study seeks to minimize reoperation rates and enhance patient outcomes. The findings could lead to better management strategies for breast cancer surgeries.

Why it matters

Potential benefit: If successful, this study could lead to reduced reoperation rates and improved surgical outcomes for breast cancer patients.

How similar studies have gone: While similar studies have explored predictive factors in breast cancer surgery, this approach aims to integrate multiple factors in a novel way to enhance clinical decision-making.
