ABSTRACT
<p><b>OBJECTIVE</b>To explore the clinical factors affecting the sensitivity of EGFR-TKI treatment in advanced non-small cell lung cancer.</p><p><b>METHODS</b>Clinical data were retrospective analyzed to determine the clinical factors affecting the outcome of 166 patients with advanced non-small cell lung cancer who received EGFR-TKI treatment in our hospttal from January of 2005 to December of 2006.</p><p><b>RESULTS</b>One hundred and nineteen patients benefited from EGFR-TKI treatment in the total of 166 patients and the disease control rate was 71.7%. Among the factors analyzed, sex, age, smoking, pathological type, brain and bone metastasis or not when EGFR-TKI was used, the time using EGFR-TKI and the level of LDH at the time of diagnosis had no significant effect on the clinical benefit rate. Among the 126 patients with serum CEA assayed at diagnosis, 84 cases had a higher serum CEA level. Compared with the patients with normal serum CEA level, the patients with a higher serum CEA level benefited more easily from EGFR-TKI therapy, with a disease control rate of 79.8% and 59.5%, respectively (P = 0.016). Among the patients who got benefits from EGFR-TKI treatment, smoking and the CEA level at diagnosis had effects on the duration of progression-free survival. The progression free survivals were 9.57 ± 6.75 months in non-smokers, 4.86 ± 3.44 months in light-smokers and 5.25 ± 4.34 months in heavy-smokers (P = 0.007). The progression free survival was 9.45 ± 7.48 months in the group with a higher serum CEA level and 6.52 ± 4.46 months in the group with normal serum CEA level (P = 0.036).</p><p><b>CONCLUSIONS</b>In patients with advanced non-small cell lung cancer, EGFR-TKIs treatment is safe and effective. The patients with high CEA level are prone to benefit from it.</p>
