Analysis of clinical factors correlated with the accuracy of colposcopically directed biopsy.

PURPOSE: Many factors affect the accuracy of colposcopically directed biopsy (CDB). This study aimed to compare the histological results of CDB with those of cone specimens and to determine clinical factors associated with the accuracy of CDB in defining the extent and severity of cervical intraepithelial neoplasia. METHODS: We studied 513 patients diagnosed with cervical intraepithelial neoplasia by CDB who underwent conization between September 2012 and December 2016. We retrospectively evaluated the agreement between histological results on biopsies and cone specimens and analyzed factors influencing the accuracy of the results. RESULTS: The overall agreement between the histological results on biopsy and the corresponding cone specimens was 74.1%; underestimation occurred in 6.4% of cases. The agreement between histological results on biopsy and cone specimen was 54.5% for low-grade lesions, 78.2% for high-grade lesions, and 28.9% for microinvasive cervical cancer. The overall agreement between high-grade cytology and the final histological diagnosis was 86.7%. By univariate analysis, patient age (p = 0.026), menopausal status (p = 0.018), type of transformation zone (p = 0.003), number of biopsies (p = 0.002), and cone width (p = 0.015) were found to be associated with the accuracy of CDB. However, multivariate logistic regression revealed that cone width (p = 0.044) was the only independent factor correlated with CDB accuracy. CONCLUSIONS: Our data suggest that old age (≥50), postmenopausal status, and transformation zone type 3 might be positively associated with the under-diagnosis of CDB. Three or more biopsies and cone width ≥21 mm might improve CDB accuracy. However, cone width was the only independent factor correlated with CDB accuracy.

[Evaluation of satisfaction after in-office conization under local anesthesia]. / Évaluation de la satisfaction des patientes après conisation en consultation sous anesthésie locale.

OBJECTIVES: Treating cervical intraepithelial neoplasia is essential in cervix carcinoma prevention and conization is the standard treatment. In the current medical and economic context, which advocates the simplification of procedures, loop excision conization is well adapted to an in-office procedure. Therefore, we evaluated the patient satisfaction after an in-office conization. METHOD: We conducted an observational study at the Besançon University Medical Centre. Between November 2013 and October 2014, all patients treated by an in-office conization were included. Global satisfaction of patient was retrospectively collected by answering a telephone questionnaire. RESULTS: Seventy patients were treated by in-office conization and answered the questionnaire. Global satisfaction was 88.6%. Moreover, 75.7% of patients declared to have felt no pain or moderate pain during the conization. Most of the patients (91.4%) would advise this in-office care to their relatives. The rate of positive margins for dysplasia was 31.4% and postoperative haemorrhage occurred in 7.1%. CONCLUSION: In this context of medical care cost reduction, conization seems to be perfectly adapted to in-office surgery. It was also found to be well accepted by patients without raising neither positive margins rate nor postoperative haemorrhage risk.

Comparison of cold knife cone biopsy and loop electrosurgical excision procedure in the management of cervical adenocarcinoma in situ: What is the gold standard?

OBJECTIVE: To compare the outcomes of patients with cervical adenocarcinoma in situ (ACIS) treated with cold knife cone (CKC) biopsy or loop electrosurgical excision procedure (LEEP) for the treatment of cervical adenocarcinoma in situ (ACIS). STUDY DESIGN: This is a retrospective, population-based cohort study of Western Australian patients with ACIS diagnosed between 2001 and 2012. Outcomes included pathological margin status and the incidence of persistent or recurrent endocervical neoplasia (ACIS and adenocarcinoma) during follow-up (<12 months) and surveillance (≥12 months) periods. RESULTS: The study group comprised 338 patients including 107 (32%) treated initially by LEEP and 231 (68%) treated by CKC biopsy. The mean age was 33.2 years (range 18 to 76 years) and median follow-up interval was 3.6 years (range <1 year to 11.8 years). Overall, 27 (8.0%) patients had ACIS persistence/recurrence while 9 (2.7%) were diagnosed with adenocarcinoma during the follow-up and surveillance periods. No patient died of cervical cancer within the study period. There were no significant differences in the incidence of persistent and/or recurrent endocervical neoplasia according to the type of excisional procedure. Patients with positive biopsy margins were 3.4 times more likely to have disease persistence or recurrence. CONCLUSION(S): LEEP and CKC biopsy appear equally effective in the treatment of ACIS for women wishing to preserve fertility. Patients undergoing conservative management for ACIS should be closely monitored, particularly if biopsy margins are positive in initial excision specimens. Patients and their clinicians should be aware of the potential risks of residual and recurrent disease.

Conization of the uterine cervix: does the level of gynecologist's training predict margin status?

The management of cervical intraepithelial neoplasia is becoming more individualized. The European Federation of Colposcopy has developed guidelines for quality assurance and also certifies specialists. The status of the resection margins of conization specimens is prognostically important and is a quality feature. We examined the rate of positive margins in conization specimens according to the training level of the gynecologic surgeon. We reviewed the hospital charts of 411 consecutive patients who underwent conization for cervical intraepithelial neoplasia or adenocarcinoma in situ between November 2006 and December 2009. Preoperative colposcopy was performed to localize and characterize the transformation zone and the lesion in all cases. Ninety-seven conizations were performed by residents, 138 by staff members, and 124 by 1 certified specialist for colposcopy. A total of 334 cold-knife conizations and 25 loop electrosurgical excision procedures were carried out. The rates of positive histologic margins in conization specimens were 16%, 22%, and 5% for residents, staff members, and the certified specialist, respectively (P<0.001). Expertise of the gynecologic surgeon in performing conization procedures appears to influence the rate of involved margins after conization. These data support quality-assured preoperative colposcopy and European Federation of Colposcopy quality assurance criteria. Specialization of gynecologic staff members in the field of colposcopy is warranted.

Positive cone biopsy specimen margins in women infected with the human immunodeficiency virus.

OBJECTIVES: The purpose of this study was to compare the positive margin rate associated with cervical conization among women who are seropositive for human immunodeficiency virus with that among women who are seronegative. STUDY DESIGN: This was a cross-sectional study of 245 women who underwent cervical conization for the following indications: biopsy-proven cervical intraepithelial neoplasia grade 2 or 3, abnormal endocervical curettage specimen, cytologic-histologic examination discrepancy, persistent cervical intraepithelial neoplasia grade 1, or abnormal cytologic characteristics with inadequate colposcopic examination. RESULTS: Twenty-two (47.8%) of 46 women who were seropositive for human immunodeficiency virus and 65 (32.7%) of 199 women who were seronegative had positive cone biopsy specimen margins. In a multivariable logistic regression the human immunodeficiency virus-seropositive women had a 2-fold increased risk of having a positive cone biopsy margin (odds ratio, 2.25; 95% confidence interval, 1.07-4.76). CONCLUSION: If the presence of positive cone biopsy specimen margins represents the potential for disease progression, then our findings of a positive margin rate of nearly 50% in a human immunodeficiency virus-positive population may argue against the kind of conservative management of colposcopic follow-up that has been proposed for immunocompetent women.

Indications for cone biopsy: pathologic correlation.

OBJECTIVE: Our purpose was to determine the ability of different indications for cone biopsy to predict the presence of disease in the cone specimen and the utility of conization for low-grade disease. STUDY DESIGN: The records were reviewed of all patients who had an excisional cone biopsy at Queens Hospital Center between 1984 and 1995. Data were gathered regarding cytologic studies, visualization of the transformation zone, colposcopically directed biopsy, and endocervical curettage. The indications for the cone procedure were grouped as being for treatment (biopsy-proved disease) (indication A), discrepancy between cytologic and histologic diagnoses (indication B), positive endocervical curettage results (indication C), and transformation zone not fully visualized (indication D), and combinations of the above. RESULTS: Two thousand nine hundred sixty-nine records were reviewed. Of these, 604 had cone biopsies. Three hundred twenty-three of 355 (91%) cone biopsies done for indication A alone had disease on the cone specimen (defined as any grade of dysplasia or condyloma). Forty of 47 (85.1%) cone biopsies done for indication B alone had disease of the cone specimen. Forty-three of 46 (93.5%) cone biopsies done for indication C alone had disease on the cone specimen. Ninety-one cone procedures were done for a combination of indications A and D, with 87 (95.6%) showing disease on the cone specimen. Thirty-one procedures were done for a combination of indications B and D, with 25 (80.6%) showing disease on the cone specimen. Cone procedures were done on 32 women for a combination of indications C and D, and 30 (93.8%) had disease on the cone specimen. Two cone procedures were done because of the colposcopic appearance alone; one had high-grade disease on the cone specimen. Age did not help to predict the likelihood that disease would be found on the cone specimen. The data were then reanalyzed to determine the likelihood of finding high-grade disease (cervical intraepithelial neoplasia grades 2 or 3 or invasive cancer) on the cone specimen. Overall, those with preoperative high-grade cytologic or histologic characteristics (cervical intraepithelial neoplasia grades 2 or 3) were much more likely to have high-grade disease (277/371 [74.7%]) than were those with preoperative low-grade cytologic or histologic characteristics (condyloma or cervical intraepithelial neoplasia grade 1) (49/233 [21.0%]) (p < 0.001). CONCLUSION: Neither age nor the preoperative grade of disease are good discriminators of the likelihood that disease will be found on a conization specimen. However, patients who have high-grade disease on the preoperative evaluation are much more likely than those with only low-grade disease to have high-grade dysplasia or cancer on a subsequent conization.

Outpatient loop electrosurgical excision procedure for cervical intraepithelial neoplasia. Can it replace cold knife conization?

OBJECTIVE: To determine if loop electrosurgical excision procedure (LEEP) can replace cold knife conization. STUDY DESIGN: In a population at high risk for invasive carcinoma, 163 cases of LEEP conization were performed with the same indications as cold knife for cervical conization. RESULTS: Seventy-five percent of LEEP surgical specimens were positive for dysplasia. Six cases showed invasive squamous cell carcinoma. No complications were seen. CONCLUSION: LEEP conization is a quick, simple and economical procedure that can safely replace most cases of cold knife conization.
