Prediction of the effect of neoadjuvant chemotherapy in patients with non-small cell lung cancer of stage III at phases of combined treatment.

: We examined 100 patients with non-small cell lung cancer (NSCLC). In addition to surgery there was performed neoadjuvant chemotherapy (2-3 cycles) EP (cisplatin at a dose of 80 mg/m2 on first day + etoposide at a dose of 120 mg/ m2 on days 1,3,5). There were studied the levels of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) as prognostic factors in the use of neoadjuvant chemotherapy in patients with NSCLC. The control group consisted of 30 healthy volunteers. The baseline level of bFGF was necessary for the prediction of combined treatment in patients with NSCLC stage III. The threshold value bFGF>10,2 ng/ml allowed predicting a good effect from chemotherapy with a sensitivity of 71,4% and specificity of 80,6%, while the sensitivity of VEGF in terms of forecasting bicycles reached 42,9 %. The resulting algorithm for predicting of the effect of neoadjuvant chemotherapy of patients with NSCLC provided perspectives to improve the outcomes of such patients.
