Abstract:
Objective This study aimed to explore the expression of tumor?derived colony?stimulating factor 1 (CSF1), its prognostic significance and underlying related mechanisms in resected lung adenocarcinoma ( ADC ) . Methods Immunohistochemistry and tissue microarray were used to detect the expression of CSF1, epidermal growth factor receptor ( EGFR), and CD68 in 266 patients with lung adenocarcinoma treated in our department between 2004 and 2008. Results In the 266 ADC cases, the positive rates of expression of CSF1, EGFR and CD68 proteins were 56. 4%, 42. 1% and 81. 2%, respectively. The expression level of CSF1 was positively correlated with TNM stage, number of involved nodal stations, tumor recurrence and EGFR expression (P<0. 05). Univariate analysis indicated that TNM stage, number of involved lymph nodes, number of involved nodal stations, CSF1 expression, the combination of CSF1/EGFR and co?expression of CSF1/CD68/EGFR were statistically significant for prognosis (P<0. 05). The results of multivariate analysis showed that TNM stage, co?expression of CSF1/EGFR and CSF1/CD68/EGFR were significant and independent risk factors for survival (P <0. 05). Correlational analysis showed that expression of CSF1 and EGFR in the tumors was positively correlated to the degree of infiltration of interstitial tumor?associated macrophages (TAMs) (respectively; P <0. 05). Conclusions The expression of CSF1 indicates a poor prognosis in postoperative lung adenocarcinoma. Co?expression of CSF1 and EGFR may be a valuable independent prognostic predictor, and its mechanism is probably involved in the interaction of cancer cells and TAMs in the progression of lung adenocarcinoma.
