Expression of brain-derived neurotrophic factor and its receptor TrkB is associated with poor prognosis and a malignant phenotype in small cell lung cancer

Coexpression of BDNF and TrkB was associated with poor prognosis in SCLC patients, and BDNF promoted the migration of TrkB-overexpressing SCLC cells. TrkB is thus a potential therapeutic target for SCLC.
