Stomatin-like protein 2 (SLP-2) is a novel cancer-related gene whose product promotes cell growth, tumorigenicity, and adhesion in human esophageal squamous cell carcinoma. The purpose of this study was to investigate whether SLP-2 is overexpressed in human laryngeal squamous cell carcinoma (LSCC) and, if so, the significance of its overexpression in relation to clinical parameters. By analyzing 124 cases of LSCC with a tissue microarray, we concluded that SLP-2 is overexpressed in LSCC as compared with the adjacent normal laryngeal epithelium (P = .000) and furthermore that SLP-2 expression correlates with clinical stage. Overexpression can be regarded as a significant prognostic factor, with higher expression being found in lymph node metastasis.
