Comprehensiveness

On this resource, the following formatting is used for comprehensiveness:

  • Minimal depth
  • (Moderate depth)
  • ((Comprehensive))
  • Generally measure estimated volume or 3 dimensions for samples greater than 0.4 cm in greatest dimension.[notes 1]
  • ((Note the color of the sample, even when unremarkable.))
  • Generally, use inking for resection margins where cancer radicality is important.Template:Ink note Excisions made by laser do not need inking on the excision surfaces, since the coagulated surface can be easily identified in the microscope.[1]
  • (Preferably photograph or make a drawing where slices have been taken.)[2]
  • Remove any surgical stitches from samples before microtomy.
  • (At least for larger samples, consider looking for medical imaging or biopsy reports in order to better guide the process.)[3]
  • Generally, strive to make slices perpendicular to visible interfaces of relevant tissues.

Notes

  1. Specifying dimensions in 3 dimensions is generally a waste of time for specimens less than 0.4 cm.
