Serum hepatocyte growth factor as a marker of tumor activity in head and neck squamous cell carcinoma.

Abstract

Hepatocyte growth factor (HGF) has previously been reported to be elevated in the serum of patients with malignancy, including breast, colorectal and gastric cancers. Here, we evaluated the correlation between serum HGF and the progression of head and neck squamous cell carcinoma (HNSCC). The mean serum HGF levels in 71 healthy control subjects, 78 patients with primary HNSCC, and eight patients with recurrent HNSCC were 0.538+/-0.163, 0.701+/-0.252, and 0.925+/-0.349ng/ml, respectively. The increase in the HGF level was significantly correlated with tumor stage progression. The HGF level had decreased to normal at 1 month after curative resection of the tumors. During follow-up for several months, the HGF level significantly increased in recurrent HNSCC patients, whereas there was no increase in nonrecurrent patients. Our data suggest that serum HGF is significantly corrected with tumor progression and may be a strong predictor of recurrence in HNSCC.
