    Abstract:
    OBJECTIVE: To explore changes in the serum tumor makers, hypoxia-inducible factor-1α (HIF-1α) 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-1α 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-specific 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-1α and VEGF levels in the control group were lower than that in observation group (p<0.01), but remarkably elevated after intervention (p<0.01). In addition, serum CEA, NSE and SCC levels were apparently lowered by treatment (p<0.01). Serum HIF-1α demonstrated a positive relation with VEGF level (p<0.01) and was inversely related with CEA, NSE and SCC levels (p<0.01). CONCLUSIONS: Significant correlations exist between marked increase of serum HIF-1α and VEGF levels and decrease of indexes related to hematological tumor markers in NSCLC patients after intervention.
