Abstract

BACKGROUND AND OBJECTIVES:

A disintegrin and metalloprotease 12 (ADAM12) has multiple domains and functions, and it plays important roles in the development of cancer. We conducted a retrospective study to determine whether the expression of the membrane type of ADAM12 (ADAM12-L) could be a prognostic factor in resected pathological (p-) stage I lung adenocarcinoma.

METHODS:

ADAM12-L mRNA expression was quantified by a reverse-transcription polymerase chain reaction in tissue samples from 84 completely resected p-stage I lung adenocarcinoma patients. The patients were divided into ADAM12-L-Low and ADAM12-L-High groups, and correlations with clinicopathologic features were obtained.

RESULTS:

Five-year survival rates of the ADAM12-L-Low and ADAM12-L-High groups were 95.1% and 71.9%, respectively. The postoperative prognosis for the ADAM12-L-High group was significantly poorer than for the ADAM12-L-Low group (P = 0.006). Multivariate analysis confirmed that high expression of ADAM12-L was an independent factor for poor prognosis (P = 0.007, hazard ratio 8.288). The ADAM12-L-High group was less differentiated and had a significantly higher rate of cancer recurrence.

CONCLUSIONS:

ADAM12-L mRNA expression is an independent prognostic factor in resected p-stage I lung adenocarcinoma, and is significantly correlated with tumor differentiation stage and postoperative cancer recurrence.
