PURPOSE: Matrix metalloproteinase (MMP) 1, MMP2, MMP3 and MMP9 are important members of the MMP family. Recently, many studies have been carried out on the association between polymorphisms of MMP1 -1607 1G/2G, MMP2 -735 C/T, MMP2 -1306 C/T, MMP3 -1171 5A/6A and MMP9 -1562 C/T and lung cancer risk. However the results of these studies remained inconclusive due to conflicting results from different case-control studies. To clarify these associations, we conducted a meta-analysis. METHODS: We conducted a comprehensive search in Medline, EMBASE, OVID and Chinese Biomedical Literature Database (date from Jan 2000 to Aug 2012). Overall and subgroup analysis by the ethnicity of study population was carried out. Odds ratio (OR) with 95% confidence interval (95%CI) were used to assess the strength of the association. RESULTS: There were 17 studies involving five polymorphic sites in four MMP genes. For MMP1 -1607,increased lung cancer risk was found under dominant model (MMP1 -1607 1G/2G: OR=1.14, 95%CI=1.03-1.26 , P=0.01 ), but not in Caucasian population. For MMP2 -1306 C/T, T polymorphism decreased lung cancer risk under dominant and recessive models (dominant, OR=0.63, 95%CI=0.46-0.88, P=0.0006; recessive, OR=0.61, 95%CI=0.38-0.99, P=0.04). For MMP9 -1562 C/T, TT genotype decreased this risk under the recessive model (OR=0.38, 95%CI=0.19-0.75, P=0.005), but not in Asian population. For MMP2 -735 C/T and MMP3 -1171 5A/6A, there was no association between this polymorphism and lung cancer risk under the dominant and recessive models. CONCLUSIONS: MMP1 -1607 1G/2G polymorphism increased lung cancer risk in Asians. It was also found thatMMP2 -1306 C/T polymorphism decreased lung cancer risk in Asians, while MMP9 -1562 C/T polymorphism decreased lung cancer risk in Caucasians. No significant difference was found in any genotype of MMP2 -735 C/T and MMP3 -1171 5A/6A. Further studies with large sample size should be carried out.
