Overexpression of Karyopherin α2 in small cell carcinoma of the cervix correlates with poor prognosis.
Background: Cervical small cell carcinoma (SCCC) is uncommon and little is known about its molecular markers. Karyopherin α2 (KPNA2) has been demonstrated in a variety of malignancies. Our objective was to determine whether the KPNA2 level is predictive of clinical outcome in patients with SCCC.
Methods: We detected KPNA2 expression by immunohistochemistry in SCCC tumors from 62 patients. The staining results were evaluated by H-score. The correlation among KPNA2 expression level, clinical characteristics, and prognosis was analyzed.
Results: KPNA2 expression was detected in tumor tissue from 55 patients with SCCC (55/62, 89%). High KPNA2 expression correlated significantly with International Federation of Gynecology and Obstetrics staging (P=0.035), tumor size (P=0.019), poorer overall survival (OS) (P=0.008), and poorer disease-free survival (P=0.004) compared to low KPNA2 expression. Multivariate analysis showed that KPNA2 expression level (P=0.037) and tumor size (P=0.046) were independent prognostic factors of OS.
Conclusions: KPNA2 may be a molecular marker and indicator of prognosis in SCCC.
期刊介绍：
The International Journal of Clinical and Experimental Pathology (IJCEP, ISSN 1936-2625) is a peer reviewed, open access online journal. It was founded in 2008 by an international group of academic pathologists and scientists who are devoted to the scientific exploration of human disease and the rapid dissemination of original data. Unlike most other open access online journals, IJCEP will keep all the traditional features of paper print that we are all familiar with, such as continuous volume and issue numbers, as well as continuous page numbers to keep our warm feelings towards an academic journal.
