| Abstract | Lysosome-associated protein transmembrane 4 beta-35 (LAPTM4B-35) is a member of the mammalian 4-tetratransmembrane spanning protein superfamily, which is overexpressed in several solid malignancies. However, the expression of LAPTM4 B-35 and its role in the progression of cervical carcinoma is unknown. The aim of this study was to determine the level of expression of LAPTM4B-35 in cervical carcinoma. Immunohistochemistry was used to determine the expression of LAPTM4B-35 protein in 53 cervical intraepithelial neoplasias (CINs) and 113 cervical carcinomas in comparison with 20 normal cervical specimens. The correlation between the expression of the LAPTM4B-35 protein and the clinicopathologic characteristics of patients with cervical carcinoma was analyzed. Statistical analysis showed that LAPTM4B-35 expression was significantly elevated in CINII/III and cervical carcinoma but not in CINI compared with the normal controls (P = 0.002, P < 0.001 and P = 0.289, respectively). In addition, the LAPTM4B-35 expression was significantly higher in both the CINII/III and cervical carcinoma cases than in the CINI cases (P = 0.021 and P = 0.002, respectively). High LAPTM4B-35 staining was present in 72.57% (82 of 113) of all the cases with cervical carcinoma. The overexpression of LAPTM4B-35 was significantly associated with the International Federation of Gynecology and Obstetrics stage (P = 0.014), tumor histologic grade (P = 0.033), lymph node metastasis (P = 0.045), and recurrence (P = 0.010). The Kaplan-Meier survival analysis showed that the high expression of LAPTM4B-35 was related to the poor overall survival and disease-free survival of patients with cervical carcinoma (P = 0.004 and P = 0.005, respectively). Multivariate Cox analysis showed that LAPTM4B-35 was an independent factor for both overall survival and disease-free survival (P = 0.015 and P = 0.016, respectively). Overexpression of LAPTM4B-35 may be associated with tumor progression in cervical carcinoma and thus may serve as a new molecular marker to predict the prognosis of cervical carcinoma patients. |
