Abstract

AIMS:

Lung cancer is the leading cause of cancer-related deaths worldwide, and it still results in a poor prognosis despite research and development of a treatment modality. Angiomotin (AMOT) was first described as a protein involved in angiogenesis, and although the oncogenic and tumour-suppressive roles of AMOT were recently reported, the biological function of AMOT has not yet been clarified. The aim of this study was thus to evaluate the relationship between reduced AMOT p130 expression and clinicopathological parameters, including patients' survival.

METHODS:

We enrolled 67 patients with lung adenocarcinoma in this study and measured the immunoreactivity of AMOT p130 in a tissue microarray. The data were analysed using a χ2 test, Cox regression hazards model and log-rank test with Kaplan-Meier curves.

RESULTS:

Reduced AMOT p130 expression is related to lung adenocarcinoma developed at a young age with statistical significance, but there is no statistical significance for the other clinicopathological parameters. Kaplan-Meier curves with log-rank test showed that reduced AMOT p130 expression had significantly better survival rate compared with the retained group (p=0.002). Univariable and multivariable analyses of the disease free survival revealed that the decreased AMOT expression was an independent prognostic factor (p=0.004, p=0.008, respectively).

CONCLUSIONS:

Decreased AMOT p130 could be an independent indicator of poor survival in patients with lung adenocarcinoma.
