It appears that the high level of SGPT is due to taxotere
. With this level (>5 times of upper limit), you have to stop taxotere for time being and wait for it to come down. After that you may try its alternative, Taxol
and see what happens.
By the way, the better way to give taxotere is to give it 3 weekly (dose is higher), while Taxol is usually given weekly. You can discuss this with your oncologist
You can continue your normal diet.
