1 Tumor Response to Combination Celecoxib and Erlotinib Therapy in Non-small Cell Lung Cancer Is Associated with a Low Baseline Matrix Metalloproteinase-9 and a Decline in Serum-Soluble E-Cadherin  Karen L. Reckamp, MD, Brian K. Gardner, PhD, Robert A. Figlin, MD, David Elashoff, PhD, Kostyantyn Krysan, PhD, Mariam Dohadwala, PhD, Jenny Mao, MD, Sherven Sharma, PhD, Landon Inge, PhD, Ayyappan Rajasekaran, PhD, Steven M.

2 FIGURE 1 Soluble E-cadherin (sEC) decreases in patients treated with celecoxib and erlotinib who achieve partial response. sEC was evaluated by enzyme linked immunosorbent assay in patient serum at baseline and at week 8 of treatment. A, All patients at weeks 0, 4, and 8, *p = 0.021—decline in patients with PR compared with those with SD and PD. Individual patient values for (B) patients with PR; (C) patients with SD; and (D) patients with PD.

3 FIGURE 2 MMP-9 is lower at baseline and after 8 weeks in patients treated with celecoxib and erlotinib who achieve partial response. MMP-9 was evaluated by enzyme linked immunosorbent assay in patient serum at baseline and at week 8 of treatment. A, All patients at weeks 0 and 8, *p = 0.006—baseline values of patients with PR compared with those with SD and PD Journal of Thoracic Oncology 2008 3, DOI: ( /JTO.0b013e bef) Copyright © 2008 International Association for the Study of Lung Cancer Terms and Conditions

4 FIGURE 3 TIMP-1 is lower in patients treated with celecoxib and erlotinib who achieve partial response. TIMP-1 was evaluated by enzyme linked immunosorbent assay in patient serum at baseline and at week 8 of treatment. A, All patients at weeks 0 and 8, *p = 0.047—decreased levels in patients with PR compared with those with SD and PD. Individual patient values for (B) patients with PR; (C) patients with SD; and (D) patients with PD.

5 FIGURE 4 CCL15 decreases in patients treated with celecoxib and erlotinib who achieve partial response. CCL15 was evaluated by enzyme linked immunosorbent assay in patient serum at baseline and at week 8 of treatment. A, All patients at weeks 0, 4, and 8, *p = 0.016—decline in patients with PR compared with those with SD and PD at week 4, **p = 0.003—decline in patients with PR compared with those with SD and PD at week 8. Individual patient values for (B) patients with PR; (C) patients with SD; and (D) patients with PD.
