PG - 182-6 AB - OBJECTIVE: To explore the feasibility and practical value of fluorescence in situ hybridization (FISH) detection of TERC gene amplification in cervical intraepithelial lesions (CIN) and squamous cell carcinoma (SCC). METHODS: Tissue microarray was constructed to cover 150 cases of various cervical conditions, including 24 cases of normal cervical mucosa, 78 cases of CINs (CINI, 25 cases; CINII, 21 cases and CINIII, 32 cases) and 48 cases of SCC. FISH was used to detect TERC gene amplification. RESULTS: TERC gene amplification was detected in 8% (2/25) CINI, 47.6% (10/21) CINII, 71.9% (23/32) CINIII and 87.5% (42/48) SCC. There were significant differences among these groups (P < 0.05). The amplification rates of TERC gene in SCC, CINIII and CINII were significantly higher than those of normal cervical epithelium and CINI (P < 0.05). Significant differences were also observed among CINI and CINII, CINIII and SCC (P < 0.05), and between CINII and SCC (P < 0.05). There were no significant differences between normal cervical epithelium and CINI, CINII and CIN III, and between CINIII and SCC (P > 0.05). FISH detection of amplification of TERC gene in CINI and CINII-III demonstrated the following statistics: sensitivity of 62.3%, specificity of 92.0%, accuracy of 71.8%, positive and negative predictive values of 94.3% and 53.5%, respectively. CONCLUSIONS: FISH detection is a reliable method in detecting TERC gene amplification using paraffin tissue sections. When histological evaluation becomes difficult, TERC amplification detectable by FISH may offer a diagnostic distinction of CINI from CINII. Moreover, TERC amplification may be used as a biomarker in predicting CIN progression to invasive cancer.
