We examined tumor-related pathologic factors and cone-related characteristics to identify parameters related to recurrence in microinvasive squamous cell carcinoma of the cervix treated with conization. This is a retrospective study on 67 consecutive cases of microinvasive carcinoma of the cervix [depth of invasion (DI) < 3 mm] treated with conization. The mean follow-up was 121 months (range 72-276 months). Four (6%) invasive recurrences were observed. Presence of lymphvascular space involvement (LVSI) was significantly related with recurrences (P < 0.05). The mean distance between tumor margin and apex of the cone (apical clearance) was 10.6 mm (range 5-22 mm), and the mean distance between lateral border of the cone and tumor margin (lateral clearance) was 6.5 mm (range 1.7-15 mm). We adopted cut-off values of 10 and 8 mm for apical and lateral clearances, respectively. We found a statistically significant difference between apical clearance and recurrence rate (P < 0.02). The LVSI was, other than DI, an important prognostic factor. Apical clearance was significantly correlated with recurrence. The cone-related characteristics, other than tumor-related pathologic factors, could help the decision concerning the definitive therapy for microinvasive carcinoma of the cervix.

    • "There is an association among Nanog, NS and Msi1 expression levels and the severity of epithelial cell changes, with expression levels highest in cells from SCC, CIN and then normal cervical epithelium. However, there were no positive correlations among Nanog, NS and Msi1 expression levels and the clinical pathological prognostic factors analyzed, indicating that overexpression of these three stem-cell-abundant proteins in cervical epithlium is not related to the prognosis of cervical carcinoma[19].

    ABSTRACT: Nanog, nucleostemin (NS) and musashi1 (Msi1) are proteins that are highly expressed in undifferentiated embryonic stem (ES) cells and have been shown to be essential in maintaining the pluripotency and regulating the proliferation and asymmetric division of ES cells and several nervous system tumor cells. The roles of Nanog, NS and Msi1 in development and progression of cervical carcinoma have, until now, not been well documented. In this study, expression of Nanog, NS and Msi1 was detected by immunohistochemistry analysis in 235 patients with various degrees of cervical epithelial lesions, including 49 with normal cervical epithelia, 31 with mild dysplasia (CIN I), 77 with moderate-severe dysplasia (CIN II-III) and 78 with squamous cervical carcinomas (SCCs). Associations with various clinical pathological prognostic variables were analyzed in 50 early-stage SCC patients. Nanog, NS and Msi1 expression levels were significantly higher in SCC patients compared with CIN patients, and were higher in CIN patients compared with those with normal cervical epithelia. Nanog expression levels showed significantly differences according to different tumor sizes (P < 0.05), whereas there were no differences in NS and Msi1 expression levels according to different clinical pathological parameters. Our findings indicate that Nanog, NS and Msi1 may be involved in carcinogenesis of the cervix and progression of cervical carcinoma.

    ABSTRACT: To assess the rate, the cumulative proportion, and the predictors of cervical intraepithelial neoplasia grades 2-3 (CIN 2-3) and invasive disease during the follow-up of patients conservatively treated for microinvasive (stage Ia1-2) squamous cell carcinoma (MIC) of the uterine cervix. Two hundred thirty women (median age, 37 years; range, 20-69 years) conservatively treated for MIC were followed up for 10 years and analyzed for cumulative proportion of CIN 2-3/invasive disease. The multivariate survival analysis was used to assess the clinicopathological features predicting the development of CIN 2-3/SCC. Of the 230 patients primarily treated by cone, 76 (33%) underwent hysterectomy as the immediate retreatment, and 13 had a residual disease. The remaining 154 women were subjected to posttreatment follow-up. The depth of stromal invasion was strongly associated with the prevalence of positive lymph nodes and lymphovascular space invasion (LVSI). The detection rate of CIN 2-3/SCC was stable at the first 2 visits (6.5% and 6.9%) and dropped thereafter. The cumulative proportion of patients whose conditions were diagnosed as CIN 2-3/carcinoma was 0.07, 0.09, 0.15, and 0.19 at 6, 12, 36, and 120 months, respectively. In multivariate survival analysis, involvement of 4 quadrants (odds ratio [OR], 5.8), LVSI (OR, 4.5), and cone margin involvement (OR, 5.6) were significant independent predictors of CIN 2-3/SCC after treatment. The upper age tertile (42-69 years) was an independent protective factor (OR, 0.3; 95% confidence interval, 0.1-0.9). A close, long-term surveillance should be scheduled for the MIC patients conservatively treated. Cone margin involvement, LVSI, and the number of quadrants involved on colposcopy are independent risk factors for disease persistence and/or progression to SCC.

    ABSTRACT: Background Treatment effectiveness and clinical outcome of patients with cervical carcinoma FIGO stage IA1 and IA2 are analyzed in three different time period at the Department of Obstetrics and Gynecology Rijeka, Croatia. Methods Retrospective analysis of the hospital chart of all cervical cancer patients between 1991 and 2005 was conducted with five-year follow up. Results Data on cervical cancer distribution by stage and five-year survival are presented. Separately analyzed age, histology type and treatment modalities in stage FIGO IA1 and IA2 during three consecutive five-year periods are presented. Conclusions Conservative surgical approach - conization alone in stage IA1 of the squamous cell car- cinoma is reasonable and safe treatment option for reproductive active women. During observed periods conization became the most used surgical technique applied in almost two third of FIGO IA1 cervical cancer patients. Lymph vascular space invasion in stage IA1 lead to adjunct pelvic lymphadenectomy with unclear clinical benefit. In cervical cancer patients stage IA2 simple hysterectomy and pelvic lymphadenectomy could be accepted as a standard treatment. In these patients further studies are recommended to evaluate other less radical surgical techniques - simple and radical trachelectomy with or without pelvic lymphadenectomy. Radical hysterectomy in both stages IA1 and IA2, based on personal experience and literature data represents a surgical overtreatment and should be aban- doned.
