MarginMarker histology marking dye and CorrectClips radiographic markers can add clarity and reduce error.

Pathologists lead the standardization of specimen marking to ensure the highest quality of analysis for all cancer patients.


The Problem

In cancer surgery, the single most important predictor of local recurrence is the tissue margins.1,2 Research indicates that using suture for specimen orientation can result in a 31% disagreement rate between the surgeon and pathologist with regard to margin interpretation.3 For specimens <20cm3, the discordance rate can be as high as 78%.3 Re-excision rates exceed 20% in breast surgery suggesting that some re-excisions
may be performed on the wrong margin.4

The Solution

MarginMarker™ sterile ink kit and CorrectClips™ radiographic markers remove inconsistencies, reducing error and ambiguity. The pathology lab receives specimens with margins accurately and uniformly marked.

Standardization

Pathology receives specimens marked with a consistent color coding scheme which completely defines each of the six tissue margins. Entire surface areas are indicated, and irregularities and fissures on the surface are clearly marked in relation to each margin.

Confidence

Validity of Markings
  • MarginMarker sterile inks define the edges of specimen margins; this is more complete than suture, which marks only one point to represent the entire margin plane, and which requires the pathologist to estimate margin boundaries.
  • Specimen markings by MarginMarker have greater validity than suture methods. CorrectClips detach easily with minimal interruption to tissue surface compared to suture. False positives can be reduced, as MarginMarker inks minimize migration into crevasses or punctures created by suture.
  • Pathologists have greater confidence that if re-excision is required, it is valid and necessary to prevent cancer recurrence, and that the designated margin for re-excision is correct.
Performance of MarginMarker Inks
  • MarginMarker sterile inks adhere throughout specimen processing; the colors show brightly on slides, easily distinguishing each margin. There is no need to apply additional ink.
  • MarginMarker sterile inks can be used when specimen sterility is maintained for cytogenetic analysis or microbiology testing.
  • MarginMarker sterile inks are packaged for single use, minimizing the risk of cross-contamination from other specimens.

Results

Clinical Benefits

Vector Surgical’s tissue margin marking system, comprised of MarginMarker and CorrectClips, provides a secure, complete and accurate designation of tissue specimen margins, potentially contributing to:

Improved Patient Outcomes

  • Lower cancer recurrence1,9
  • Improved cosmesis6,8
Efficiency
  • Promotes clear, systematic pathologist-surgeon communication
Compliance
  • MarginMarker and CorrectClips are in compliance with 2012 CAP Accreditation Guidelines for specimen handling by maintaining margin designation during fixation10
