Summary

Biopsies can spread tumor cells, but excising the biopsy track during surgery reduces this risk. Marking the biopsy site with Indian ink improves visibility for complete track excision.

Area of Science:

  • Oncology
  • Surgical Pathology

Background:

  • Biopsy procedures, including fine needle and trocar techniques, carry a risk of iatrogenic tumor seeding along the biopsy tract.
  • This seeding can potentially lead to local recurrence or metastasis, complicating patient outcomes.

Purpose of the Study:

  • To evaluate methods for reducing the risk of tumor cell seeding via biopsy tracts.
  • To propose a practical technique for enhancing the identification and excision of biopsy tracts during subsequent surgical procedures.

Main Methods:

  • Review of existing literature on tumor seeding from biopsy procedures.
  • Proposal of using Indian ink as a fiducial marker for biopsy tracts.

Main Results:

  • Excision of the biopsy tract at the time of surgery is a recognized method to mitigate seeding risk.
  • Needle and trocar punctures may leave minimal or no visible evidence at the time of surgery, hindering complete tract excision.

Conclusions:

  • Excision of biopsy tracts is crucial for minimizing iatrogenic tumor cell spread.
  • Indian ink marking of biopsy sites offers a reliable method to ensure complete excision of the biopsy tract during surgery, thereby reducing cancer seeding risk.
