Levels of the DNA adduct, N7-methyldeoxyguanosine, are associated with increased risk of failure of treatment of cervical intraepithelial neoplasia.

OBJECTIVE: To determine whether exposure to methylating agents was a risk factor for treatment failure in women undergoing colposcopic examination. METHODS: Nine hundred fifty-eight women attending for colposcopic examination after abnormal cervical smear test results were recruited into the study cohort. Information on demographic factors, smoking and other risk factors was obtained and a pre-treatment biopsy was taken and stored at -70 degrees C. After follow-up, cases who had treatment failure of cervical intraepithelial neoplasia (CIN) within 2 years following treatment were identified (n = 77) and matched to women with no treatment failure of CIN in this time period (controls, n = 154). DNA was extracted from the pre-treatment biopsies and levels of N7-methyl-deoxyguanosine (N7-MedG), a marker of exposure to methylating agents, were quantified as the ring-opened form of the base damage by a validated immunoslotblot assay. RESULTS: Sufficient DNA for N7-MedG analysis was extracted from 61 subjects corresponding to 20 matched case control pairs. N7-MedG was detected in cervical DNA with levels ranging from non-detected (<0.1 micromol/mol dG) to 4.83 micromol/mol dG. N7-MedG levels were significantly higher in cases (geometric mean 0.99 micromol/mol dG) than controls (0.33 micromol/mol dG; P = 0.01). There were no associations between N7-MedG levels and HPV or smoking status. Log N7-MedG content, after adjustment for HPV status at time of treatment, was found to be significantly associated with increased risk of treatment failure (OR 5.74, 95% CI 1.05-31.23). CONCLUSIONS: The association between pre-treatment levels of DNA damage induced by methylating agents and subsequent treatment failure implicates methylating agent exposure as a causative factor in treatment failure.

Could precolposcopy information and counseling reduce women's anxiety and improve knowledge and compliance to follow-up?

OBJECTIVE: To investigate the effects of precolposcopy counseling on women's anxiety, knowledge about colposcopy and compliance to follow-up. METHODS: Two hundred and twenty women referred for colposcopy for the first time were recruited. They attended precolposcopy sessions in which written and video information were given and subsequently were randomized to have either further explanation and discussion with an experienced colposcopic nurse (study group) or no further discussion (control group). Each subject completed a Chinese version of the state-anxiety questionnaire (STAI) and a knowledge questionnaire before and immediately after the precolposcopy sessions and also before the colposcopy examination. Women's concern and opinion on the programme were also assessed. Follow-up data was compared with those who did not attend the precolposcopy sessions. RESULTS: Women's knowledge about colposcopy significantly improved after the precolposcopy sessions. The improvement was more significant in the study group than in the control group immediately after the sessions (P = 0.003). The difference between the groups in knowledge scores remained statistically significant before colposcopic examination (P = 0.015) but the difference diminished between these two assessment points. There was no statistically significant difference between the two groups in the anxiety scores at all assessment points. Women who attended the precolposcopy sessions had a significantly higher attendance rates and better compliance to follow-up than those who did not attend the sessions. CONCLUSION: Precolposcopy session with explanation and discussion improves women's knowledge about colposcopy, but has negligible effects on women's anxiety before colposcopy. Provision of written and video information at the precolposcopy sessions can improve compliance to follow-up after colposcopy.

Primary cervical lymphoma: report of two cases and review of the literature.

BACKGROUND: Primary lymphoma arising from the female genital tract has been rarely encountered. Primary cervical lymphoma is even rarer in gynecologic oncology practice and accounts for approximately only 1% of extranodal lymphomas. In this article, two cases of cervical lymphoma are presented with a review of the available literature. CASE HISTORIES: A 51-year-old woman presented with abnormal vaginal discharge. On pelvic examination, cervix was apparently normal; however, a solid and mobile pelvic mass was palpated. Pap smear was reported as HSIL at another institution. Radiological evaluation revealed a cervical mass with a 3 cm diameter. Histopathological evaluation of LEEP material was reported as diffuse large B cell lymphoma. We performed abdominal hysterectomy plus bilateral salphingo-oopherectomy and the patient was treated with adjuvant 6 cycles of CHOP chemotherapy. A second case was a 49-year-old postmenopausal woman who had undergone a routine gynecologic follow-up examination without any complaint at another institution. Routine cytological smear revealed HSIL. Punch biopsy under colposcopic examination presented no remarkable pathology except for a benign inflammation. Due to discordance between cytology and histology, LEEP was performed under colposcopic examination, which revealed follicular lymphoma grade III. This patient was treated with 6 cycles CHOP chemotherapy without any surgery. CONCLUSION: Primary cervical lymphoma is a rare disorder. Although most reported cases in the literature have a normal Pap smear, some may represent with co-existent cytological abnormalities. Therefore, cervical lymphomas should be kept in mind in patients with cytological abnormalities.

Diagnostic and therapeutic laser conization for cervical intraepithelial neoplasia.

OBJECTIVE: The clinical efficacy of conservative treatment using Nd-YAG laser technique for cervical intraepithelial neoplasia (CIN) was evaluated in a large series of CIN patients based on the long-term follow-up results. METHODS: We have treated 2107 women preoperatively diagnosed as having CIN by Nd-YAG contact laser conization with vaporization of the base. Their postoperative histologic findings and clinical outcomes were evaluated. RESULTS: The cone specimen was reported as showing that 1956 (92.8%) of 2107 cases had no CIN or CIN 1-3 and 151 (7.2%) cases had invasive diseases. 1956 cases without invasive diseases were followed up for 16 to 252 months. Incomplete excision occurred in 230 (12.3%) of 1874 patients with CIN lesion in the cone specimen, but failure rate (persistence or recurrence) was only 1.2%. 192 (83.5%) of 230 postoperative CIN patients with positive surgical margins showed no abnormal cytology or colposcopy during follow-up period. Preoperative underdiagnosis of biopsy results compared with cytologic or colposcopic findings elevated the risk for incomplete excision and failure rate. CONCLUSION: The combination of laser excision and vaporization of the base was useful to detect unexpected invasive disease and revealed excellent therapeutic effects for CIN. Preoperative cytologic or colposcopic findings should be taken into account for the conservative treatment of CIN.

Usefulness of combining testing for p16 protein and human papillomavirus (HPV) in cervical carcinoma screening.

OBJECTIVE: To evaluate the value of the combination of p16 and HPV detection in the screening for cervical cancer. METHODS: 186 patients with previous abnormal cervical lesion were studied. After colposcopic examination, two conventional Pap slides were prepared: the first was Papanicolaou-stained and examined by cytologist; the second was immunocytochemically stained for p16. Cervical cells were collected by brush using for HPV detection by Hybrid Capture II. Biopsy of any colposcopically abnormal lesions was performed. RESULTS: The 186 cervical samples were classified cytologically as normal (148), ASCUS (13), low-grade (11), high-grade (12) dysplasia and squamous cell carcinoma (2). P16 and HPV were found in all high-grade dysplasia and SCC, and in 64% and 27% of low-grade dysplasia, 62% and 0% of ASCUS and 7.4% and 3.4% of normal, respectively. 18 of p16-positive cases (11%) were HPV-negative, 14 of them in the ASCUS and normal group. Compared to histological results, all of the p16-positive cases of squamous metaplasia, CIN II/III and SCC were HR-HPV-positive. Therefore, the cases that were positive for both with normal cytology (5 cases) or low-grade dysplasia (3 cases) may comprise a high-risk group for neoplastic change. CONCLUSION: The combination of p16 and HPV detection may be useful in cervical cancer screening to identify high-risk patients requiring early and proper management.

Papillomavirus detection: demographic and behavioral characteristics influencing the identification of cervical disease.

OBJECTIVE: This study was undertaken to assess the association between detection of high-risk types of human papillomavirus and various demographic and behavioral characteristics and to further relate this association to cervical histopathologic findings. STUDY DESIGN: A total of 1007 patients with a Papanicolaou test result reported as high-grade squamous intraepithelial lesion or with 2 results reported as atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion were referred from city and county clinics to a colposcopic clinic. All women had a cervical smear obtained, underwent colposcopically directed biopsy and endocervical curettage, and had a specimen taken for human papillomavirus deoxyribonucleic acid detection by polymerase chain reaction. Demographic information was obtained from each patient. RESULTS: Human papillomavirus deoxyribonucleic acid was identified in 655 (66%) of the specimens. High-risk human papillomavirus types (16, 18, 31, 33, and 35) were detected in 463 (70.7%) of these specimens. The prevalence of evidence of human papillomavirus (koilocytosis) and grade 1 cervical intraepithelial neoplasia in the biopsy specimen decreased significantly with age, whereas the prevalence of grade 2 or 3 cervical intraepithelial neoplasia in the biopsy specimen increased with age. There was a significant age-dependent decreasing trend in detection of high-risk human papillomavirus deoxyribonucleic acid among women who had human papillomavirus-associated changes, grade 1 cervical intraepithelial neoplasia, and grade 2 or 3 cervical intraepithelial neoplasia in the biopsy specimen. The prevalences of high-risk human papillomavirus among patients with grade 1 cervical intraepithelial neoplasia and grade 2 or 3 cervical intraepithelial neoplasia were similar, and both were significantly higher than among women with no evidence of cervical intraepithelial neoplasia or koilocytosis in the biopsy specimen. Risk factors associated with grade 2 or 3 cervical intraepithelial neoplasia were different from those associated with human papillomavirus-associated changes and with grade 1 cervical intraepithelial neoplasia. CONCLUSION: The detection of high-risk human papillomavirus was age-dependent for all histologic categories. Patients with grade 2 or 3 cervical intraepithelial neoplasia had a prevalence of high-risk human papillomavirus that was similar to that among women with grade 1 cervical intraepithelial neoplasia but significantly higher than that among women whose biopsy specimens appeared normal or demonstrated only the presence of human papillomavirus-induced changes (koilocytosis). This suggests that separation of human papillomavirus-associated changes only from grade 1 cervical intraepithelial neoplasia may be of significance in tissue diagnosis.

Cervical findings in rape victims.

The difficulty of documenting genital findings in rape victims by gross visualization is well known. However, we report two cases in which cervical findings were readily established by colposcopic examination and photography. Use of the colposcope may significantly increase the reliability of establishing findings in rape victims.

Cytology and colposcopy in the diagnosis and management of preclinical carcinoma of the cervix uteri: a learning experience.

This report presents a learning experience in the use of colposcopy in the management of 254 patients consecutively and personally studied in whom one or more Papanicolaou smears suggested a cervical intraepithelial neoplasia or early invasive carcinoma. The accuracy of cytology in predicting the degree of cervical intraepithelial neoplasia and early invasive carcinoma, within the limits of confidence of the laboratory, was 84.5 per cent. The accuracy of the colposcopic impression, within the limits of confidence, was 83.5 per cent. When only those lesions that could be satisfactorily examined were considered, the accuracy of the colposcopic interpretation within the limits of confidence was found to be 96.4 per cent. Neoplastic lesions limited to the ectocervix, and lesions that extended from the ectocervix into the lower portion of the endocervical canal and lesions limited to the canal were significantly related to the age of the patient. Of the total group of 254 patients examined, 45 patients (17.7 per cent) were subjected to a diagnostic cone biopsy.

Relevance of human papillomavirus screening in management of cervical intraepithelial neoplasia.

OBJECTIVE: To evaluate the utility of human papillomavirus detection in identifying women with abnormal Papanicolaou smears who can be safely followed up with cytologic study only, we conducted a study to determine the sensitivity, specificity, and negative and positive predictive values of a Food and Drug Administration-approved human papillomavirus test kit for detection of cervical intraepithelial neoplasia in colposcopically directed biopsy specimens. STUDY DESIGN: We enrolled women with abnormal Papanicolaou smears referred to a colposcopy clinic serving indigent patients. All 1128 women had a referral Papanicolaou smear, a clinic Papanicolaou smear, and a sample for human papillomavirus deoxyribonucleic acid test; 1075 underwent colposcopically directed biopsies and endocervical curettage. We used the HPV Profile kit for human papillomavirus testing. RESULTS: Of 486 women with low-grade squamous intraepithelial lesions on Papanicolaou smear, 35.4% had high-risk human papillomavirus deoxyribonucleic acid detected, and of 592 with high-grade lesions, 44.4% had high-risk human papillomavirus detected. Among 527 women with biopsy specimens showing cervical intraepithelial neoplasia and in 267 with cervical intraepithelial neoplasia grades 2 or 3, 38.7% and 56.2% had high-risk human papillomavirus deoxyribonucleic acid detected. However, the sensitivity of human papillomavirus deoxyribonucleic acid detection to identify biopsy-confirmed cervical intraepithelial neoplasia grades 2 or 3 was 55.7%, and the positive predictive value of the test was only 34.9%. CONCLUSION: Human papillomavirus appears to be causally associated with cervical cancer but human papillomavirus screening does not appear to be of value to identify women with abnormal Papanicolaou smears who can be safely followed up with cytologic study alone.

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.

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.

A randomized comparison of the effects on vaginal and cervical epithelium of a placebo vaginal ring with non-use of a ring.

Little is known about the effects of contraceptive vaginal rings on the vaginal surface epithelium, although most studies have not demonstrated any significant deleterious effect. However, one study found that some medium-to-long-term levonorgestrel-releasing ring users developed chronic erythematous and ulcerative lesions in the posterior vaginal fornix. Subsequently, this ring was completely redesigned (IVR-2) with different dimensions and much greater flexibility. The first version of IVR-2 was designed as a placebo ring to explore effects on the vagina and cervix without addition of a progestogen. One-hundred-sixty-six healthy sexually active women volunteers were recruited in four centers and randomly assigned for 6 months to either placebo ring use or control (non-use) using a predetermined randomization code generated by WHO in a 2:1 ratio. Careful inspections of the vaginal and cervical epithelium were performed with a colposcope at admission and at 2-month intervals. No clinically significant lesions were detected in any center either among ring users or controls. However, a number of minor changes in appearance of the vaginal and cervical epithelium (erythema, petechiae, ecchymosis, and minor aceto-white changes) were described from the Sydney Center, some of which were present on admission and some of which were found on subsequent examination. Ten of eleven "red" changes on the cervix and vagina were noted in IVR-2 users, and only one in the controls, suggesting a contribution by the IVR-2 to minor epithelial surface changes. Five of ten resolved completely with continued ring use. There was no correlation in this study between epithelial changes and cigarette smoking or frequency of intercourse in the 14 days prior to colposcopic examination but a significant relationship between tampon use in the last 7 days and all epithelial changes (p = 0.05) and especially red changes (p = 0. 027) was noted. Red changes were significantly less likely to be found among condom users (p = 0.007). The IVR-2 placebo ring did not produce clinically significant changes in the vaginal epithelium and cervical mucosa and a carefully controlled and randomized study should be considered to compare the epithelial appearances in women using a placebo IVR-2 and one releasing 20 microg levonorgestrel.

A new vaginal antimicrobial contraceptive formulation: phase I clinical pilot studies.

Pilot clinical trials were performed with a new vaginal suppository called "Long Acting, Sustained Release of Spermicide" ("LASRS"). No visual or colposcopic lesions or patient complaints occurred as a result of using LASRS with increasing doses of nonoxynol-9 (up to 20%) for 5 days or of applying the highest dose of nonoxynol-9 (20%; total 400 mg) for 8 h. Colposcopic or visual lesions were also not induced when LASRS with 20% nonoxynol-9 was used for 7 consecutive days by the study participants except for those who developed symptomatic monilia vaginitis. Symptoms were reported although these were mostly minor. A long-lasting, bioadhesive, translucent layer (film) of formulation formed over the vaginal and cervical surfaces. Postcoital spermicidal studies showed LASRS to be highly effective for prolonged periods of time. Although intercourse was delayed for 5 to 8.5 h after insertion of the formulation, an average of only 0. 2 motile sperm/HPF could be found in cervical mucus. These studies suggest LASRS to possess advantages over presently marketed formulations by having long-term efficacy and by forming a bioadhesive, presumably protective layer over the genital tract epithelium. The results also suggest the formulation to decrease the vaginal irritation caused by nonoxynol-9 as noted by colposcopy. These pilot data support a more extensive study with the LASRS suppository.

Smoking as a risk factor for preinvasive and invasive cervical lesions in female sex workers in Venezuela.

OBJECTIVES: To determine whether the number of cigarettes smoked per day and years of smoking were risk factors for preinvasive and invasive cervical lesions in Venezuelan female sex workers. METHODS: The clinical history of 438 female sex workers (FSWs) was taken and each received a gynecological examination, a Pap smear, and a colposcopic examination. A colposcopically-guided cervical biopsy was taken when the epithelium appeared abnormal. RESULTS: The FSWs' mean age was 32.16+/-8 years. Age at first sexual intercourse was 15.9+/-2 years, parity was 4.1+/-2.3, live births were 3+/-3, and age at first delivery was 16.6+/-4.7 years. Cervical biopsies were performed in 84 FSWs. Sixty-four of them (76.2%) had preinvasive or invasive lesions and 47 (73.4%) were current smokers (Relative Risk) (RR), 1.26; 95% confidence interval (CI), 1.02-1.55; P<0.03]. FSWs who smoked more than 20 cigarettes per day had an increased RR to get a premalignant or malignant cervical lesion (RR, 1.27; 95% CI, 1.02-1.52; P<0.03). There was no statistically significant difference between FSWs who smoked 20 cigarettes or more per day and FSWs who smoked less than 20 cigarettes per day (RR, 1.36; 95% CI, 0.81-2.29; P<0.25). FSWs who had been smoking for 5 years or more were at risk to develop preinvasive or invasive cervical lesions (RR, 1.37; 95% CI, 1.01-1.86; P<0.04). CONCLUSIONS: The risk for FSWs to develop preinvasive or invasive cervical lesions increased with the number of cigarettes they smoked per day and their years of smoking.

Laser miniconization procedure.

OBJECTIVE: To describe the outpatient procedure of minimal conization with free-hand guided high power density carbon dioxide laser for simultaneous diagnosis and treatment of CIN producing a one-piece tissue specimen for histological examination. MATERIAL AND METHODS: 3100 non-pregnant patients with mild, moderate or severe dysplasia in pap smear, having colposcopically proved ectocervical lesions but without evidence of invasive carcinoma, or 85 pregnant patients with severe dysplasia in pap smear having extensive colposcopic signs of at least carcinoma in situ were admitted for this treatment. This outpatient procedure including cervical curettage is performed under local anesthesia to excise a one-piece 5 mm (during pregnancy 7 mm) deep minicone. RESULTS: The degree of patient discomfort, bleeding complications, postoperative pain, infection or vaginal discharge were all minimal. The procedure was fast, causing minimal thermal damage of resection lines of the minicone specimen. Histopathological examination of the non-pregnant minicones revealed microinvasive or invasive carcinoma in 1.2%, the primary cure rate was 96.1%. During pregnancy, 13.3% malignancy was found. No unexpected sudden onset of invasive carcinoma was recorded during the 15-year follow-up and the cumulative risk of recurrence for all forms of CIN was 3.02% CONCLUSIONS: The outpatient miniconization procedure, performed with a free-hand guided 60-W high power density CO2 laser is a reliable method for simultaneous diagnosis and treatment of CIN. Because of the paucity of complications, this procedure may also be appropriate during pregnancy.

Conservative treatment of low grade squamous intraepithelial lesions (LSIL) of the cervix.

OBJECTIVE: To assess the accuracy of the cervical smear and colposcopy in diagnosing low grade squamous intraepithelial lesions (LSIL), and the natural history of LSIL. METHOD: The cytological, colposcopic and histological findings of 145 patients with a smear diagnosis of LSIL were compared, and the final outcome studied. RESULTS: The diagnosis of LSIL either by cytology alone or in combination with colposcopy was associated with a rate of overdiagnosis of 11.7% and 6.9%, respectively, and a rate of underdiagnosis of 31.0% and 26.2%, respectively. Spontaneous regression of lesions occurred in 81.1% of patients with proven LSIL, with regression within 24 months in 4/5 of cases. CONCLUSIONS: The degree of dysplasia shown in the cervical smear correlated poorly with histology. All patients with cervical smear showing LSIL should have colposcopy and colposcopic-directed biopsy to exclude the presence of more advanced lesions. In the absence of some serious lesions, it is then acceptable to observe the patient for 24 months before adopting definite treatment, as spontaneous regression is common.

Risk factors for early cytologic abnormalities after loop electrosurgical excision procedure.

OBJECTIVE: To evaluate risk factors for early cytologic abnormalities and recurrent cervical dysplasia after loop electrosurgical excision procedure (LEEP). METHODS: A retrospective analysis was performed of all pathology records for LEEPs performed at our institution from January 1996 through July 1998. Follow-up cytology from 2 through 12 months after LEEP was reviewed. Patients with abnormal cytology were referred for further colposcopic evaluation. Statistical analysis using chi2 test for trend, proportional hazards model test, Fisher exact tests, and life table analysis were performed to identify risk factors for early cytologic abnormalities after LEEP and to determine relative risk of recurrent dysplasia. RESULTS: A total of 298 women underwent LEEP during the study period, and 29% of these had cytologic abnormalities after LEEP. Grade of dysplasia, ectocervical marginal status, endocervical marginal status, and glandular involvement with dysplasia were not found to be independent risk factors for early cytologic abnormalities. However, when risk factors were analyzed cumulatively, the abnormal cytology rate increased from 24% with no risk factors to 67% with three risk factors present (P =.037). Of patients with abnormal cytology after LEEP, 40% developed subsequent dysplasia, and the mean time to diagnosis was approximately 6 months. The relative risk of subsequent dysplasia ranged from a 20% increase to twice the risk if post-LEEP cytology was low-grade squamous intraepithelial lesion or high-grade squamous intraepithelial lesion, respectively. CONCLUSION: Based on these results, consideration should be given for early colposcopic examination of patients who have evidence of marginal involvement or endocervical glandular involvement with dysplasia. These patients are at increased risk for abnormal cytology and recurrent dysplasia. This initial visit should occur at 6 months, as the mean time to recurrence of dysplasia was 6.5 months.

Laser conization assisted by crypt visualization for cervical intraepithelial neoplasia.

OBJECTIVE: To describe intraoperative visualization of crypts and its effects on specimen clearance, safety, and clinical results of excisional treatment of cervical intraepithelial neoplasia (CIN). METHODS: We treated 147 patients with high-grade CIN (II-III) and colposcopically-assessed endocervical extension, using a CO2 laser instrument in a day-hospital setting. Endocervical walls were stained preoperatively with a 2% methylene blue aqueous solution. Cervical conization was done by laser under colposcopic vision. Stromal incision and cone shape were directed laterally to the endocervical crypts by intraoperative visualization in transparency of the stain. RESULTS: We were able to make stromal incisions at minimal and uniform radial distances from the cervical canal, thus allowing individualized cone shape and optimal bleeding control. Median (range) base diameter and height of specimens were 18 (13-24) and 20 (15-26) mm, respectively. The final histologic diagnosis was CIN II in 35 patients, CIN III in 111, and microinvasive carcinoma in one. Endocervical disease extension was confirmed in 103 patients (70%); the median (range) length of CIN in the 99 evaluable cases was 15.6 (0.5-25.7) mm, and crypt involvement was found in 39 (26.5%). All lateral margins were free of dysplasia. Four specimens (2.7%) had positive apical margins. No significant complications occurred, and fertility did not seem to be impaired. With a median (range) follow-up period of 68 (60-92) months, only 1.4% of patients experienced recurrence; two patients, both with involved crypts, had recurrent dysplasia at 23 and 45 months, respectively. CONCLUSION: Laser microsurgical conization assisted by crypt visualization facilitates safe and complete removal of CIN extending into the endocervix.
