Human error in marking breast excision margins is significant. This study shows inconsistent margin marking, questioning the safety of reexcision procedures in breast conserving surgery.

Area of Science:

  • Surgical Oncology
  • Pathology
  • Medical Imaging

Background:

  • Close or involved excision margins after breast conserving surgery often lead to reexcision.
  • Accurate margin assessment is crucial for effective treatment and preventing positive margins.

Purpose of the Study:

  • To quantify human error in marking breast excision margins.
  • To evaluate the reliability of identifying and marking specimen margins for pathological assessment.

Main Methods:

  • An experimental model simulating breast excision margins was created.
  • Computer software measured surface areas to compare human-painted margins with control measurements.
  • Six volunteers marked the margins of the experimental model.

Main Results:

  • Marking of breast excision margins by humans showed considerable variability.
  • Thirty percent of hand-painted surfaces deviated by 20% or more from control measurements.
  • The deep surface, consistently painted last by volunteers, was significantly larger than controls.

Conclusions:

  • This study highlights significant human error in marking imaginary boundaries on breast excision models.
  • The findings raise concerns about the safety and accuracy of targeting single margins during reexcision procedures.
  • Improved methods for margin assessment in breast surgery are warranted.
