Is this liver mets?

I am currently on taxol/herceptin and concerned about possible liver mets. My onc does want to do scans. I have been experiencing occassional stomach pain high on my right side, sometimes stabbing. I noticed it after the last two infusions and sometimes after eating. Also my liver function tests are high and taxol was reduced on 2 occassions but they continue to be high. My onc tells me the liver function tests show that taxol is contibuting to the high counts.
Does anyone know what Alkaline Phosphatese, Transaminase-SGPT, Transaminase-SGOT represent? Anyone else experiencing pain?
THanks for your help
