Tumour Reduce

My father tumor in the liver has reduce in size. Previously the length was 36mm and now it has reduce to 27mm. The lung tumour looks about the same but has flatten.
The clinical trial medicine by Abbott has indeed help my father condition to improve. The ABT-869 is mixed with Ensure Plus milk and taken at night. The major side effect are fatigue and loss of appetite. As my father complain of pain, the doctor has reduce the ABR-869 dosage to 12.5mg. The next review will be one month later.
