Serum Tumor Markers, Hypoxia-Inducible factor-1α HIF-1α and Vascular Endothelial Growth Factor, in Patients with Non-small Cell Lung Cancer Before and after Intervention

摘要

Objective: To explore changes in the serum tumor makers, hypoxia-inducible factor- (HIF- ) and vascular endothelial growth factor (VEGF) level and their relations in patients with non-small cell lung cancer (NSCLC) before and after intervention. Materials and Methods: Forty patients with NSCLC and 40 healthy individuals undergoing physical examination in our hospital provided the observation and control groups. HIF- and VEGF levels in serum were detected by enzyme-linked immuno-sorbent assay (ELISA) in the observation group before and after intervention and in control group on the day of physical examination, along with serum carcino-embryonic antigen (CEA), neuron-speci ic enolase (NSE) and squamous cell carcinoma antigen (SCC) levels in the observation group with a fully automatic biochemical analyzer. Clinical effects and improvement of life quality in the observation group were also evaluated. Results: The total effective rate and improvement of life quality after treatment in observation group were 30.0% and 32.5%, respectively. Serum HIF- and VEGF levels in the control group were lower than that in observation group (p demonstrated a positive relation with VEGF level (p and VEGF levels and decrease of indexes related to hematological tumor markers in NSCLC patients after intervention.
