Pathology questions?

[Cal-Gal]

Hello Ladies and Gentleman,

I am still learning on this journey--and while I am done with my chemo regiment--I still have questions regarding my surgical path report.

What do the following notations on my pathology refer to?

1.) "Intermediate for Lymphovascular invasion"-it notes that D2-40 immuno stain examined--when I looked and found that--(I think in the lymph node biopsy noted area.) It noted this;
"equivocal, foci suspicious for lymhovascular invasion not present on stain." I was rated negative or 0/1 node. And what are foci??

2.) Ki-67 20%?

3.) SPR(tubule,nuclear, mitotic) Score 8/9 on 3 tumors 7/9 on the other?

I found through reading etc. that #1 refers to the spread of cells into the bloodstream--not sure if that is correct or not? and that is usually reported as positive or negative? mine is intermediate?

I found through reading that #2 and #3 refer to a metric to score the rate at which a tumor is growing?--but I could not find what the actual scores or numbers really mean.

I would appreciate any of you that have any feedback or explanations for me.

I remain high on life today---and grateful for all of you---
