Delayed Selective Sentinel Node Biopsy for Patients Undergoing Mastectomy for DCIS

Feasibility Study on Delayed Selective Sentinel Node Biopsy for Patients Undergoing Mastectomy for Ductal Carcinoma in Situ

Sponsor

Seoul National University Hospital

Enrollment

84 participants

Start Date

Jun 13, 2023

Study Type

INTERVENTIONAL

Conditions

DCIS

Summary

In the case of a patient undergoing total mastectomy for intraductal carcinoma (DCIS), the sentinel lymph node is not excised during the primary surgery but only marked for identification. If the final histological examination confirms invasive cancer, delayed surgery is performed to remove the sentinel lymph node that was marked during the initial surgery. primary endpoint : The success rate of identifying the sentinel lymph node that was marked during the primary surgery in cases where the final histological examination confirms invasive cancer is evaluated. addendum) The previously documented Breast-Conserving Surgery has been corrected to reflect the accurate procedure of Total Mastectomy.

Eligibility

Inclusion Criteria3

Patients diagnosed with DCIS through histological examination.
Patients undergoing mastectomy

Exclusion Criteria4

In cases where imaging tests or physical examinations suggest possible lymph node metastasis.
In patients who have previously undergone axillary lymph node surgery on the same side as the current procedure.
