Transforming growth factor-?1 level correlates with angiogenesis, tumor progression, and prognosis in patients with nonsmall cell lung carcinoma

TGF-beta1 seems to affect tumor angiogenesis and to play an important role in tumor progression in patients with nonsmall cell lung carcinoma. Furthermore, the TGF-beta1 protein level may be an independent predictor of survival in patients with adenocarcinoma of the lung.
