Survival rates according to tyrosine hydroxylase (TH) expression in peripheral blood at diagnosis. (A) The 5-year progression-free survival (PFS) was lower in TH-positive than in TH-negative patients (63.8±6.9% vs. 94.7±2.1%, p < 0.001). (B) In analysis confined to high-risk patients, the probability of 5-year PFS was lower in TH-positive than in TH-negative patients (55.7±8.2% vs. 89.6±5.8%, p=0.001). (C) Among TH-positive patients, a higher expression level of TH was associated with a worse outcome (above median level vs. below median level: 5-year PFS, 52.9±10.0% vs. 75.7±8.8%, p=0.075).
