Tumor deposits

(Review)

Scott Campbell
  1. Colon/appendix (easier)
  2. Melanoma (satellites) (harder)
  1. Colon - This model holds for colon.  Some discussion of the use of characterizes = metastatic  discontinuous spread, but general agreement reached that this term both suffices and is accurate.

2. Melanoma (microsatellite) - Definition needs to stay primitive as definition of discontinuous spread from one part of the skin to another part of the skin structure AND within 2 cm cannot be modelled with necessary and sufficient conditions

2Tumor bud (Review)

Scott Campbell

Will leave as primitive....no way to model "cluster of cells at leading edge of invasive component of neoplasm"

  1. Presence of tumor buds - growth process << budding  

    Process could be defined as "budding" and included in the proliferation process qualifiers.  Then this could be considered sufficiently defined.  For now, concept will be left primitive

  3. Number of tumor buds.  This concept must be left primitive for now as there is no way to describe a tumor bud which consists of 1-4 cells at the leading edge of the invasive neoplasm.

3PatternsScott Campbell
  1. How to handle patterns within histologies
    1. Lung (Lepidic, acinar)
    2. DCIS
    3. Bladder (differentiation)

4Treatment effectScott Campbell

Continue discussion:

What are we measuring when assessing "treatment effect"?  

Is this a histologic change?  Viability of tumor cells?

  1. Primary site
  2. Lymph node

  2. Local metastases - sidedness? 
  3. count of local metastases
