MMP3 and cancer: A study by AbdRaboh et al. [24] showed that MMP3 rs3025058 6A allele carriers had an almost threefold increased risk for advanced (III–IV)-stage cancer (OR = 2.9, 95% CI 1.04–8.45, p < 0.05) but, in concordance to our findings, did not reveal association with the status of lymph nodes.
