Taking appropriate actionable steps (treatment vs. active surveillance) based on intra-operative gross surgical margin assessment and post-operative histological evaluation could make the difference between a durable/curative outcome or a devastating early recurrence in your cancer patients following surgical resection.   The panel of world-renowned surgical and medical Oncologists and Pathologist will focus their discussions on the following tumors on which differing views are widespread:

  • Extremity Soft Tissue Sarcomas – Marginal vs. Wide Surgical Resection
  • Mast Cell Tumors – Metric vs. Proportional Surgical Margins
  • Histologic Margins – Making sense of narrow or close margins

The above topics are addressed via an exchange of discussion points and case-discussions  debated between the 3 panelists.  The discussion will conclude with an interactive discussion on what actionable steps can and should be taken based on the result of margin assessment.
