Specimen margins are best defined by the surgeon, who knows the original shape and position of the tissue during surgery.
In cancer surgery, the single most important predictor of local recurrence is the tissue margins.1,2
Customary methods used to label tissue margins cause error. Medical research shows discordance rates of 31% to 52% in the identification of specimen margins between surgery, pathology and radiology.3,4 This error may lead to unnecessary re-excisions or cancer recurrence.5
Vector Surgical’s Tissue Orientation System, consisting of MarginMarker sterile tissue dyes and CorrectClips radiographic markers, provides secure and accurate designation of specimen margins, potentially resulting in more accurate re-excisions,6,7 fewer unnecessary re-excisions,6,8,9 lower cancer recurrence1,10 and improved cosmesis.7,9
Surgeons have greater confidence that if re-excision is required, it is valid and necessary to prevent cancer recurrence. Using MarginMarker and CorrectClips, there is greater certainty that the designated margin for re-excision is the correct margin featuring abnormal tissue. MarginMarker and CorrectClips help to ensure that tissue margins are interpreted consistently across the OR, radiology and pathology.
Vector Surgical’s tissue marking system, comprised of MarginMarker sterile tissue dyes and CorrectClips radiographic markers, provides a secure, complete and accurate designation of tissue margins potentially contributing to improved patient outcomes.
Improved Patient Outcomes
- More accurate re-excisions6,7
- Fewer unnecessary re-excisions6,8,9
- Potentially lower cancer recurrence when complete resection is accomplished1,10
- Better cosmesis due to re-excision of less tissue7,9
Valuable Time Saved
- More efficient surgeon-pathologist communication
- Less risk of needle stick in the OR
