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.

Plain Language Summary

Simplified for easier understanding

This study is looking at whether a sentinel lymph node biopsy — a procedure to check if breast cancer has spread to nearby lymph nodes — can safely be delayed until after mastectomy rather than done at the same time, for patients with DCIS (a very early, non-invasive form of breast cancer). **You may be eligible if...** - You are 20–75 years old - You have been diagnosed with DCIS (ductal carcinoma in situ) confirmed by biopsy - You are scheduled for mastectomy **You may NOT be eligible if...** - Your biopsy shows signs of invasive (spreading) cancer - You have already had sentinel node biopsy or lymph node removal - You have had previous breast surgery or radiation to the same breast Talk to your doctor to see if this trial is right for you.
