OBJECTIVE: To examine the correlation between cervical cytology and final histological results in patients who have undergone loop electrosurgical excision procedure (LEEP) with or without colposcopy-directed biopsy. METHODS: A retrospective review was performed of 829 patients who underwent LEEP for abnormal cervical cytology at Gangnam Severance Hospital between January 2004 and December 2008. Patients were classified to three groups according to cervical cytology and also divided into two groups based on the treatment they received: see-and-treat group and the standard three-step group. Final histological results were compared for the each study group. RESULTS: There were no differences in the final histological results between see-and-treat and three-step group in patients with high-grade squamous intraepithelial lesions (HSIL) cytology (N=523) (p=0.71). However, in patients with low-grade squamous intraepithelial lesions (LSIL)/atypical squamous cells of undetermined significance (ASCUS) (N=257) or normal cytology (N=49), the final histological results were significantly different between see-and-treat and three-step group (p<0.001) and the rate of overtreatment was significantly higher in the see-and-treat group (p<0.001). CONCLUSION: A see-and-treat protocol may be a viable alternative only in patients with HSIL cytology if colposcopic impression is suggestive of cervical intraepithelial neoplasia (CIN) 2 or 3 lesions.

OBJECTIVE: The aim of this study was to identify human papillomavirus (HPV) in cervical intraepithelial neoplasia (CIN) and to evaluate the persistence of HPV after loop electrosurgical excision precedure (LEEP). METHODS: Records of 138 patients with LEEP performed due to cervicitis, CIN I, CIN II and CIN III were reviewed and persistence of HPV were followed up at 3, 6, 9 and 12 month after LEEP treatment from January 1996 to December 1999. RESULTS: Among 202 patients, 138 cases (68.3%) were showed HPV positive before LEEP and histologic findings were showed as cervicitis 20 cases (14.5%), CIN I 23 cases (16.7%), CIN II 31 cases (22.5%) and CIN III 64 cases (46.3%). Persistence of HPV after LEEP treatment were 10.9% (15/138) at 3 month and 2.9% (4/138) at 6 month. However, among 15 cases of persistent HPV, only 5 cases (33.3%) were showed an abnormal Pap smear at 3 month after LEEP. CONCLUSION: Human papillomavirus (HPV) was eliminated over 90% at 3 month after LEEP treatment in CIN. Detection of HPV was helpful to estimate therapeutic effect and to predict the recurrence or persistence of CIN after LEEP treatment.

The carcinoma of uterine cervix is the most common malignant neoplasm in Korean women. Nearly all invasive cervical carcinomas are preceded by a intraepithelial stage. The cervical intraepithelial lesion(CIN) is subdivided into I, II, and III, depending on the severity of the changes. To evaluate the histologic characteristics of the CIN, we studied the CIN III by mapping of the uterine cervix. The results were as follows. 1. The CIN III without I or II was 54.8%(17/31 cases). 2. The multifocal CIN III was 12.9%(4/31 cases). 3. The horizontal growth of CIN III was 38.7%(12/31 cases). These results indicate that the CIN III is unifocal and CIN III without I or II is more common.

OBJECTIVE: To evaluate Fragile histidine triad (Fhit) and p53 expression pattern in cervical intraepithelial neoplasm (CIN) and invasive cervical cancer, and to verify the correlation between the loss of Fhit and clinicopathological parameters of invasive cervical carcinoma and the relationship between Fhit and p53 expression. METHODS: 10 low-grade squamous intraepithelial lesions (LSIL), 16 high-grade squamous intraepithelial lesions (HSIL), and 21 invasive cervical carcinomas were evaluated by immunohistochemical staining for Fhit and p53 primary antibody. Their expression patterns in CIN and invasive cervical cancer were analysed semiquantitatively as positive and negative by the staining area and intensity. Clinicopathological data were obtained by review of patients' hospital records. RESULTS: Compared with CIN (LSIL and HSIL), invasive cervical carcinoma showed significantly loss of Fhit expression (p<0.05). P53 expression did not show the significant difference between CIN and invasive cervical cancer. There was no relationship between loss of Fhit and p53 expression in CIN and invasive cervical cancer. But loss of Fhit expression in invasive cervical cancer was also significantly associated with FIGO stage (p<0.05). CONCLUSION: Our results suggest that loss of Fhit expression may play an important role in the malignant transformation of CIN to invasive cancer. However, further molecular studies are needed to elucidate the role of Fhit gene in the carcinogenesis of cervical cancer.

OBJECTIVE: In cervical intraepithelial neoplasia (CIN), p16INK4a immunohistochemistry has been reported to be a useful diagnostic biomarker. However, limited information is available about the association between the p16INK4a immunohistochemistry and the outcomes of CIN. Here, we report p16INK4a immunohistochemistry as an effective biomarker to predict the outcomes of CIN. METHODS: p16INK4a immunohistochemistry was performed in patients with CIN from January 2000 to August 2009. Among these patients, we have performed a retrospective analysis of the medical records to evaluate the outcome of CIN 1-2 and performed statistical analysis to determine the correlation between p16INK4a expression and the outcomes. We also performed HPV genotyping and analyzed the relation between the infecting human papillomavirus (HPV) genotype and the outcomes. RESULTS: A total of 244 patients, including 82 with CIN 1, 60 with CIN 2, and 102 with CIN 3, were examined. The rate of p16INK4a overexpression increased with increasing CIN grade, 20.7% for CIN 1, 80.0% for CIN 2, and 89.2% for CIN 3, with significant differences between CIN 1 and CIN 2-3 group. In the 131 CIN 1-2 patients, the progression rate was significantly higher for the patients showing p16INK4a overexpression than for those not showing p16INK4a overexpression (p=0.005); the regression rate was also found to be significantly lower for the patients showing p16INK4a overexpression (p=0.003). High-risk HPV genotypes were detected in 73 patients (73.7%). Both progression and regression rates were not significantly different between the high-risk HPV-positive and HPV-negative groups (p=0.401 and p=0.381, respectively). CONCLUSION: p16INK4a overexpression was correlated with the outcome of CIN 1-2, and p16INK4a is considered to be a superior biomarker for predicting the outcome of CIN 1-2 compared with HPV genotyping.
