Crazy metastisis with lobular
Hello… I was originally diagnosed with ILC in 2013, stage 2B with three lymph nodes positive. I was ER positive and her2 negative. Had double mastectomy, 8 rounds of ACT and 5 years of AI. Now I have been diagnosed with malignancy in a lymph node in porta hepatic which is where blood vessels feed into the liver and other major organs. There was no malignancy found in the liver though. This is a strange scenario. I just received my path report which states the following:
In porta hepatic lymph node: Positive for metastatic carcinoma with aprocrine features
Tumor cells are positive for GATA3 and CK7 and negative for PAX8, GCDFP and mammoglobin. Although breast origin is favored, GATA3 is not specific for breast primary.
Liver wedge is benign hepatic parenchyma with no metastatic carcinoma
I am not surprised at these results but don't understand the GATA3, CK7, etc or what it means for outcomes or what treatment I will need.
Has anyone had any experience with lobular cancer metastasizing to anodd area of the body? This is so confusing and will have to speak to my oncologist about how this is treated. Thank you for your thoughts
