Matrix metalloproteinase inhibitor reversion- inducing cysteine-rich protein with Kazal motifs: a prognostic marker for good clinical outcome in human breast carcinoma.

BACKGROUND: The recently described reversion-inducing cysteine-rich protein with Kazal motifs (RECK) inhibits membrane Type 1 matrix metalloproteinase (MMP-14), MMP-2, and MMP-9 secretion and enzymatic activity. Its expression is essential for normal vasculogenesis. Down-regulation of RECK has been implicated in tumor angiogenesis and progression. METHODS: The authors assessed the prognostic value of RECK expression in tumor tissue specimens from 278 breast carcinoma patients with a median follow-up time of 75 months (range, 2-169 months). RECK mRNA levels were measured by real-time quantitative reverse transcriptase-polymerase chain reaction. RESULTS: Expression levels of RECK were lower in tumor tissue specimens than in adjacent normal breast tissue specimens from 10 patients (P = 0.028). No relevant associations of RECK with established clinicopathologic factors or treatment regimens were found. RECK expression predicted a longer recurrence-free survival time (RFS; P = 0.037) at the optimal cutoff value (hazard ratio, 0.66; 95% confidence interval, 0.44-0.98). The 100 patients whose tumors exhibited low levels of RECK had a mean RFS time of 80.4 months and a 61.8% 5-year RFS rate, whereas the 178 patients with tumors with high RECK expression had a mean RFS time of 91.2 months and a 73.0% 5-year RFS rate. Multivariate Cox regression analysis showed that RECK expression maintained a significant independent prognostic value for RFS time (P = 0.047). CONCLUSIONS: These results are in agreement with the notion of RECK being an important tumor-suppressor gene. Therefore, the possibility of applying RECK, a pharmaceutical mimetic, or drugs activating endogenous RECK expression, as possible therapeutic or preventive agents for breast carcinoma should be explored.[1]
