Hi,
Liver metastasis is common with gastrointestinal primary cancer. Other possibilities are lung cancer, breast cancer. CK 20 negative result rules out colon primary, Ck 7 negative rules out Lung primary. Other possible markers are GCDFP for breast cancer. In case of no primary tumor indentification, tumor to be called as CUP ( carcinoma of unknown primary) and to be treated with broad spectrum chemotherapy. Consult your oncologist.
