Management of histologic abnormalities of the cervix.

The American Society for Colposcopy and Cervical Pathology sponsored a consensus conference in 2001 to develop evidence-based guidelines for women with histologic abnormalities of the cervix. The options for management of cervical intraepithelial neoplasia 1, 2, and 3 are ranked according to the strength of the recommendation and the quality of the evidence. Follow-up with repeat cytology at six and 12 months or DNA testing for high-risk types of human papillomavirus at 12 months is the preferred management approach for women with cervical intraepithelial neoplasia 1 and satisfactory initial colposcopy. If results from repeat cytology are reported as atypical squamous cells of undetermined significance or greater, or if DNA human papillomavirus testing is positive for oncogenic types of the virus, repeat colposcopy is preferred. When the initial colposcopy is unsatisfactory, a diagnostic excisional procedure is preferred. Follow-up without treatment is acceptable only in women who are pregnant and adolescents with cervical intraepithelial neoplasia 1 who had unsatisfactory colposcopy. Biopsy-confirmed cervical intraepithelial neoplasia 2 and 3 requires treatment except during pregnancy and in compliant adolescents with cervical intraepithelial neoplasia 2 and negative endocervical curettage. When colposcopy is satisfactory, treatment includes ablative or excisional procedures. A diagnostic excisional procedure is recommended in women with biopsy-confirmed cervical intraepithelial neoplasia 2 or 3 and unsatisfactory colposcopy.

Preparing digitized cervigrams for colposcopy research and education: determination of optimal resolution and compression parameters.

OBJECTIVE: Visual assessment of digitized cervigrams through the Internet needs to be optimized. The National Cancer Institute and National Library of Medicine are involved in a large effort to improve colposcopic assessment and, in preparation, are conducting methodologic research. MATERIALS AND METHODS: We selected 50 cervigrams with diagnoses ranging from normal to cervical intraepithelial neoplasia 3 or invasive cancer. Those pictures were scanned at 5 resolution levels from 1,550 to 4,000 dots per inch (dpi) and were presented to 4 expert colposcopists to assess image quality. After the ideal resolution level was determined, pictures were compressed at 7 compression ratios from 20:1 to 80:1 to determine the optimal level of compression that permitted full assessment of key visual details. RESULTS: There were no statistically significant differences between the 3,000 and 4,000 dpi pictures. At 2,000 dpi resolution, only one colposcopist found a slightly statistically significant difference (p = 0.02) compared with the gold standard. There was a clear loss of quality of the pictures at 1,660 dpi. At compression ratio 60:1, 3 of 4 evaluators found statistically significant differences when comparing against the gold standard. CONCLUSIONS: Our results suggest that 2,000 dpi is the optimal level for digitizing cervigrams, and the optimal compression ratio is 50:1 using a novel wavelet-based technology. At these parameters, pictures have no significant differences with the gold standard.

The role treatment for cervical intraepithelial neoplasia plays in the disappearance of human papilloma virus.

OBJECTIVE: To explore the role played by excision of the transformation zone in women diagnosed with cervical intraepithelial neoplasia (CIN) in the disappearance of human papillomavirus (HPV). MATERIAL AND METHODS: In a retrospective, cohort study, women with CIN who were treated by loop electrosurgical excision procedure of the transformation zone were compared with another group of women with CIN who were managed expectantly. The decision to treat or manage expectantly was made by one of the authors on clinical grounds. All patients were evaluated with cervical cytologic analysis, pathologic examination of excised tissue, and HPV DNA testing, which was considered positive when high-risk HPV types were detected. Among women treated with loop electrosurgical excision procedure, the median lag time was calculated from diagnosis of CIN to treatment. The median time for conversion from HPV-positive to HPV-negative status in both groups was compared, as well as the 1- and 2-year cure rates (defined as converting to HPV-negative status) in the treated and untreated groups. RESULTS: In the treated group, 12% had CIN 1, 83% had CIN 2,3, 2% had cancer, and 3% had normal pathologic results. In the untreated group, 82% had CIN 1, 16% had CIN 2,3, and 2% had normal pathologic results (p < 0.0001). The lag time from the initial diagnosis of CIN to treatment was less than 1 month. The median follow-up time was 7 months (range, 1-121 months) in the treated group and 13 months (range, 1-70 months) in the untreated group. The 1-year rates of conversion to HPV-negative status, defined as the cure rates in the treated and untreated groups, were 65% (+/- 6%) and 23% (+/- 7%), respectively, and the 2-year cure rates in the treated and untreated groups were 90% (+/- 4%) and 56% (+/- 11%), respectively (p < 0.0001). Median time to conversion to a negative HPV status was 7.7 months for the treated patients compared with 19.4 months in the untreated patients (p < 0.0001). CONCLUSIONS: Women treated by loop electrosurgical excision procedure are more likely convert to HPV-negative status at 1 and 2 years and do so significantly sooner than those managed expectantly.

Differentiating high-grade cervical intraepithelial lesion from atrophy in postmenopausal women using Ki-67, cyclin E, and p16 immunohistochemical analysis.

OBJECTIVE: In postmenopausal women, differentiating high-grade cervical intraepithelial neoplasia (CIN 2,3) from atrophic uterine cervical squamous epithelium histologically may pose a diagnostic challenge. Recent studies have indicated the value of using a combination of Ki-67, cyclin E, and p16 immunohistochemical analysis in recognizing CIN 2,3. In this study, we compared the staining features of Ki-67, cyclin E, and p16 in cervix specimens from postmenopausal women to distinguish CIN 2,3 from atrophy. METHODS: Twenty-six formalin-fixed paraffin-embedded archival cervical specimens (4 biopsy, 8 laser cone, and 14 total hysterectomy samples) were selected from 25 women 50 to 80 years of age (mean = 64 years). Cases included CIN 2,3 (n = 10), atrophy (n = 9), and coexistent CIN 2,3 and atrophy (n = 6). Slides were stained with monoclonal antibodies to Ki-67, cyclin E, and p16 using the avidin-biotin-peroxidase method. Strength of staining was graded as 1+ to 3+. Pattern of staining was described as diffuse, patchy, or scattered. Ki-67 staining restricted to the basal/parabasal zone was scored as negative. RESULTS: All CIN 2,3 cases demonstrated variable positivity for Ki-67, cyclin E, and p16. Most CIN 2,3 cases showed strong p16 (81.3%) and Ki-67 (75.0%) reactivity, while only 31.3% of them showed strong cyclin E activity. Some CIN 2,3 cases demonstrated strong p16 but weak Ki-61 and cyclin E reactivity. All atrophic epithelia were negative for p16, cyclin E, and Ki-67. In coexistent CIN 2,3 and atrophy cases, the three-antibody panel clearly demarcated the transition from benign to neoplastic epithelia. CONCLUSION: P16 is the most valuable marker followed by Ki-67 for differentiating CIN 2,3. While cyclin E appears to add limited value on these two markers. Therefore, although the three-antibody immunohistochemical panel (p16, Ki-67, and cyclin E) can be a valuable adjunct to routine hematoxylin-eosin staining, it is also possible to use the two-antibody panel (p16 and Ki-67) to effectively distinguish CIN 2,3 from atrophy in postmenopausal women.

The clinical usefulness of human papillomavirus testing in the follow-up of women after treatment for cervical intraepithelial neoplasia.

OBJECTIVE: To compare the effectiveness of human papillomavirus (HPV) testing and cervical cytologic analysis in monitoring patients after treatment for cervical intraepithelial neoplasia. MATERIALS AND METHODS: A retrospective study comparing cytologic analysis and HPV testing using the follow-up protocol recommended by the American Society for Colposcopy and Cervical Pathology Consensus Conference. Sixty-one patients were seen for a total of 193 follow-up patient visits. In 120 visits, both cytologic and HPV results were available. Specificity, sensitivity, positive and negative predictive values, and the rate of referral to colposcopy were calculated. RESULTS: In 68 visits, both HPV and cytologic results were negative, and in 19, both were positive. In 21 visits, cytologic results were positive and HPV results were negative, and in 12 visits, cytologic results were negative and HPV results were positive. The specificity of cytologic analysis and HPV testing was 68.3% and 75.8%, respectively (p = .16). The positive predictive value for cytologic analysis and HPV testing was 6.5% and 7.5%, respectively, and the negative predictive value was 100% and 98.9%, respectively. Had either test been used alone, cytologic analysis would have referred 40 patients to colposcopy and HPV testing would have referred 31 patients. Had both been used in combination, 52 patients would have required colposcopy with no significant improvement in the amount of disease detected. CONCLUSIONS: Both cytologic analysis and HPV testing are equally effective in monitoring patients after treatment for cervical intraepithelial neoplasia. The simultaneous use of cytologic analysis and HPV testing significantly increased colposcopy referrals without increasing the amount of disease detected.

Endometrial cells in pap smears of postmenopausal women: cytohistologic correlation.

OBJECTIVE: To evaluate the significance of endometrial cells in Papanicolaou (Pap) smears of postmenopausal women. MATERIALS AND METHODS: We reviewed all Pap smears of postmenopausal women from 1992 to 1999. Follow-up endometrial tissue obtained within 1 year of any Pap smear containing benign endometrial cells or foamy histiocytes was also reviewed. RESULTS: A total of 159 Pap smears containing benign endometrial cells or foamy histiocytes were identified. Fifty-six patients were excluded; 34 patients had no histiologic follow-up; 12 had insufficient tissue on endometrial sampling; and 10 had atypical glandular cells on cytologic analysis. Endometrial pathologic features were identified in 31 patients (30%), including 21(20%) with polyps, six (6%) with endometrial hyperplasia, and four (4%) with adenocarcinomas. Hormonal replacement therapy was not a factor associated with these endometrial adenocarcinomas. Six of the 10 patients with significant endometrial pathologic features (simple and complex endometrial hyperplasia or adenocarcinomas) were referred for evaluation based solely on their cytologic abnormality showing benign endometrial cells or foamy histiocytes. CONCLUSIONS: Both benign endometrial cells and foamy histiocytes on Pap smears in postmenopausal women are associated with endometrial pathologic features. Benign endometrial cells may carry a greater risk than foamy histiocytes.

Teaching operative dictation. A survey of obstetrics/gynecology residency program directors.

OBJECTIVE: To assess current efforts to teach operative dictation in obstetrics and gynecology residency programs. STUDY DESIGN: A survey detailing the didactics of operative dictation was distributed in a single mailing to all program directors listed in the roster of the Council on Residency Education in Obstetrics and Gynecology. RESULTS: Of 274 surveys distributed, 115 (42%) were returned. Ten percent of program directors reported defined curricula related to operative dictation. Using a combination of lectures, personal instruction and review of previous notes, attendings and senior residents share the responsibility for teaching operative dictation in the majority (78%) of programs. Sixty percent of program directors were in favor of more formal guidelines for residency education in the technique of operative dictation, 34% were opposed, and 6% offered no opinion. CONCLUSION: Obstetrics and gynecology residency programs rarely have a structured curriculum for teaching operative dictation, and the majority of program directors support the institution of more formal guidelines.

In vitro conventional cytology historical strengths and current limitations.

Despite the fact that cervical cytology screening programs have dramatically reduced the prevalence of cervical cancer in the US, women continue to develop and die from the disease. The most important observation contributing to this failing is that 60% of women with invasive cancer have not had a Pap smear in the previous 5 years (or have never had one). The most clinically effective and cost effective approach to reducing the incidence of cervical cancer is to screen the unscreened population. Recent evidence has also noted that the sensitivity of conventional cytology is also much lower than was previously believed. Much recent investigation has been directed at identifying the reasons for this low sensitivity and identifying ways to improve it. Only by improving the sensitivity of cervical cancer screening and participation in screening programs can the prevalence, morbidity, and mortality from cervical cancer be further reduced.

Colposcopy quality control for clinical trials: the positive effects from brief, intensive educational intervention.

OBJECTIVE: To determine whether a brief, intensive colposcopy course improves the cognitive skills of colposcopists participating in clinical trials. MATERIALS AND METHODS: Twenty-two colposcopists involved in a multicenter clinical trial attended an intensive colposcopy course designed to improve diagnostic skills. Participants completed a pretest and posttest of 10 case-based studies and the ASCCP Colposcopy Recognition Award (CRA) examination. Pre- and posttest exam and CRA results were compared for each individual and the group. RESULTS: The group mean pre- and posttest total scores were 67% and 73%, respectively. There was a significant improvement in posttest colposcopic impression mean scores compared with the pretest (56% and 44%, respectively). The greatest improvement in colposcopic impression mean scores was for low-grade, high-grade, and cancer cases; 25%, 23%, and 20%, respectively. CRA scores did correlate positively with pretest scores. CONCLUSION: A brief, intensive colposcopic educational program improved the cognitive skills of the colposcopists.

Can cervicography be improved? An evaluation with arbitrated cervicography interpretations.

OBJECTIVE: The purpose of this study was to estimate the optimal performance of cervicography. We compared an arbitrated cervigram classification with an arbitrated referent diagnosis of cervical neoplasia. STUDY DESIGN: From an initial group of 8460 women, a stratified sample of cervigrams from 3645 women and histologic information from 414 women underwent arbitration. Interobserver agreement was assessed for cervicography and the referent diagnosis. Sensitivity, specificity, and predictive values were estimated for initial and arbitrated cervicography results, compared with the initial and arbitrated referent diagnoses. RESULTS: For the detection of arbitrated high-grade lesions or cancer, arbitrated cervicography yielded an overall sensitivity of 63.9% and a specificity of 93.7%. Significantly higher sensitivity was associated with younger age and age-related visual characteristics. CONCLUSION: Optimization of the cervigram classification improved performance over a single interpretation in this population but suggested the limits of static visual screening.

Atypical glandular cells of undetermined significance: significance of cell type and age on patient management.

OBJECTIVE: To compare the rate, accuracy, and histological correlation of cytological smears reported as atypical glandular cells of undetermined significance (AGUS) in different age groups. MATERIALS AND METHODS: Cervical cytology smears reported as AGUS were reviewed and correlated with histologic follow-up and repeat cytology. RESULTS: A total of 40,464 Pap smears were performed at Long Island Jewish Medical Center between 1996 and 2000. Of those, 163 (0.4%) smears were diagnosed as AGUS, and 62% of the patients with AGUS had either histologic or cytologic follow-up or both. The highest AGUS rates occurred in the fifth (0.6%) and ninth (0.84%) decades of life. Eighty-eight patients had histologic follow-up. Significant endometrial lesions occurred in 15 patients. The mean age was 64 years. Significant cervical lesions occurred in 12 patients. The mean age was 45 years. Among women with AGUS-favor endometrial (AGFEM) cell origin, 9 of 34 women had a significant lesion (8 endometrial and 1 cervical). Four of 12 endometrial carcinomas were identified among women whose cytology suggested cervical origin. CONCLUSIONS: Older women were more likely to have significant endometrial lesions and younger women significant cervical lesions. However, neither cytologic criteria nor the patient's age is perfect in directing the clinician toward the likely origin of the atypical cells.
