Gross processing

Gross tumors according to organ and/or tumor type (as per above) whenever possible. In additional to general gross processing guidelines, the following instructions are usually acceptable:

  • Identify surgical margins where tumor involvement may be necessary to identify or negate.
  • Generally ink such margins.
  • Section the specimen so as to get a gross overview of tumor extent.
  • (Take a gross photograph of the tumor.)
  • Describe the tumor, minimally by color and consistency (firm/rubbery versus semisolid), and possibly also including diffuse versus well-demarcated.
  • Measure tumor dimensions and distances to relevant margins.
  • Sampling of generally at least one slice per centimeter of tumor (which for larger tumors may be submitted as 2-3 sections per cassette).

The most important aspects of a tumor is whether it is malignant or not, and staging. Further information: Evaluation of suspected malignancies
