Application

Application Comment Organism
medicine progression-free survival significantly longer in high FUCA activity group than in low FUCA activity group, not correlated to clinical response to trastuzumab but maybe useful as biomarker for predicting progression-free survival for trastuzumab treatment, serum FUCA activity correlates with early detection in hepatocellular carcinoma Homo sapiens
medicine may be useful as a biomarker for predicting the progression-free survival of for trastuzumab treatment Homo sapiens
