Comparing preoperative and pathologic tumor sizes in breast cancer

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

Incheon St.Mary's Hospital · NCT06505577

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.

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.

Who should consider this trial

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

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

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 performed: 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.
