ABSTRACT The frequency of positive cone margins and its significance in cervical intraepithelial neoplasia are under controversy. The purpose of the current study was to identify factors associated with positive cone margin status and to evaluate its clinical significance in high-grade cervical intraepithelial neoplasia. Medical records of women who underwent loop electrosurgical excision procedure at the Soroka Medical Center (January 2001-July 2011) were reviewed retrospectively. Patient age, extent of dysplasia, endocervical glands involvement, positive margin status, type of margin involved, degree of margin involvement, and postcone endocervical curettage results were evaluated as possible factors associated with persistent/recurrent disease. A total of 376 women were included in the study. Cone margin involvement was observed in 33% (endocervical-22%, ectocervical-8%, both margins-3%). Factors significantly associated with cone margin involvement were older age (older than 35 y), widespread dysplasia in the cone specimen (≥4 sections) (P<0.001 for each), and endocervical glands involvement (P=0.003). Fifty patients (13%) had persistent/recurrent disease. Involvement of the cone margins (focal: hazard ratio=17, P<0.001; extensive: hazard ratio=28, P<0.001) and older age (hazard ratio=1.18 for every 5 additional years, P=0.03) were associated with persistent/recurrent disease. We conclude that women older than 35 yr with widespread high-grade dysplasia in the cone specimen and involvement of endocervical glands are more likely to have positive cone margins. Positive cone margins, particularly when extensively involved, and increased patient age are associated with persistent/recurrent disease. These factors should be considered while planning for further management.

    ABSTRACT: Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Identification of precancerous lesions has been primarily by cytologic screening of cervical cells. Cellular abnormalities, however, may be missed or may not be sufficiently distinct, and a portion of patients with borderline or mildly dyskaryotic cytomorphology will have higher-grade disease identified by subsequent colposcopy and biopsy. Sensitive and specific molecular techniques that detect HPV DNA and distinguish high-risk HPV types from low-risk HPV types have been introduced as an adjunct to cytology. Earlier detection of high-risk HPV types may improve triage, treatment, and follow-up in infected patients. Currently, the clearest role for HPV DNA testing is to improve diagnostic accuracy and limit unnecessary colposcopy in patients with borderline or mildly abnormal cytologic test results.

    ABSTRACT: The prognostic significance for residual or recurrent disease of cervical intraepithelial neoplasia Grade III in endocervical glands by cone biopsy was examined in 341 consecutive patients diagnosed from 1979 through 1983 and followed through 1988. Treatment by hysterectomy, within 8 weeks of cone biopsy, was done in 96 patients. The only variable that could predict residual disease at hysterectomy was positive margins (P = 0.059). However, both positive margins and positive glands were (independently of one another and after the effects of length of follow-up, hospital of admission, and age at time of first diagnosis were held constant) highly significant predictors of residual or recurrent disease in the 245 women who did not undergo a hysterectomy (P = 0.000 for each). The authors therefore conclude that information concerning gland involvement on cone biopsy specimens should influence patient management.

    ABSTRACT: In 51 of 106 patients (48%) residual disease was identified in hysterectomy specimens performed following cervical conization. Invasive squamous cell carcinoma was found in one patient in spite of clear cone margins. Thirty-nine of sixty-three patients (62%) with cervical intraepithelial neoplasia (CIN) involving the inner (endocervical) margin of the cone biopsy had residual disease. When both the inner margin and post-cone endocervical curettage (ECC) were involved, residual disease was present in 24 of 30 (80%) hysterectomy specimens. When the inner margins of the cone were involved with CIN-III and the post-cone ECC was negative, 36% of hysterectomy specimens contained residual disease compared to 88% when post-cone ECC was positive. These findings indicate that post-cone endocervical curettage has significant predictive value with respect to the presence or absence of residual disease in patients with CIN involving the inner margins of the cervical cone.
