OBJECTIVE: To determine the interpretability and significance of the traditional factors used to predict residual dysplasia in hysterectomy specimens after loop conization. MATERIALS AND METHODS: Loop electrosurgical cervical conization was performed on 372 patients. Ninety three women had a hysterectomy within 6 months of the loop conization. Residual disease was defined as cervical intraepithelial neoplasia or cancer in the hysterectomy specimen. RESULTS: Of the 93 patients having a subsequent hysterectomy, 36 (38.7%) has residual disease in their hysterectomy specimen. The mean age of the patients with residual disease in the post loop conization hysterectomy specimen was 42.22. The mean age of those free of residual disease was 29.42. By multivariate analysis, dysplasia involving the ectocervical margin (p = 0.34) and the endocervical margin (p = 0.35) was not predictive of disease in the hysterectomy specimens. Endocervical curettage (p = 0.005), glandular involvement (p = 0.01), loop conization pathology findings (p < 0.05) and cytological examination (p < 0.001) were predictive of residual dysplasia. CONCLUSIONS: Cytological reports, increasing age, severity of disease, gland involvement and endocervical curettage were the only factors that accurately predicted residual dysplasia. The presence or absence of dysplasia in the loop conization, ectocervical margin and endocervical margin was not predictive of residual dysplasia in post loop conization hysterectomy specimens.  相似文献

OBJECTIVE: To quantify the risk of residual invasion when cervical conization reveals microinvasive squamous carcinoma and to determine whether any factors affect this risk. METHODS: We reviewed the charts and histopathology slides of 87 women who underwent a conization that contained microinvasive squamous carcinoma, followed by either a repeat conization or hysterectomy. Depth of invasion, number of invasive foci, and status of the internal margin and post-conization endocervical curettage (ECC) were assessed. The findings were correlated with the presence of residual invasion. RESULTS: Significant predictors of residual invasion included status of the internal margin (residual invasion present in 22% of women with an involved margin versus 3% with a negative margin; P < .03) and the combined status of the internal margin and post-conization ECC (residual invasion in 4% of patients if both negative, 13% if one positive, and 33% if both positive; P < .015). Depth of invasion and number of invasive foci in the conization specimen were not significant. The power of this study to detect a 25% difference in the risk of residual invasion was 73% for depth of invasion and 75% for number of invasive foci. CONCLUSION: Women with microinvasive squamous carcinoma in a conization specimen in which both the internal conization margin and post-conization ECC are negative have a low risk of residual invasion and are candidates for follow-up or simple hysterectomy. If either the internal margin or the post-conization ECC contains dysplasia or carcinoma, the risk of residual invasion is high and warrants repeat conization before definitive treatment planning.  相似文献

OBJECTIVE: Our purpose was to study the feasibility of conservatively managing selected cases of dysplasia involving endocervical cone margins. STUDY DESIGN: A retrospective review of patients conservatively managed after being found to have squamous cell dysplasia involving the endocervical margins of their cervical cone biopsy specimens. In phase I patients who had cold-knife conization with positive endocervical margins underwent repeat Papanicolaou smears and colposcopy, with biopsies and endocervical curettage as indicated. Those found free of disease were followed up with frequent Papanicolaou smears. In phase II patients with dysplasia to the endocervical resection edges on loop electrical excision procedure biopsy specimens were followed up with frequent cytologic studies. RESULTS: In phase I, 31 patients with positive endocervical margins on cold-knife conization and no evidence of dysplasia on reevaluation were followed up for 1 to 18 years. Dysplasia was detected in one patient during cytologic surveillance. In phase II, 11 patients were followed up for 12 to 31 months; only one patient has dysplasia. CONCLUSION: Selected patients with squamous cell dysplasia at endocervical cone biopsy margins may avoid additional surgery.  相似文献

OBJECTIVE: To determine how the loop electrosurgical excision procedure (LEEP) compares to cold knife conization in providing an adequate diagnostic specimen. STUDY DESIGN: Between 1991 and 1995, 95 patients underwent either diagnostic LEEP or cold knife conization at Allegheny University Hospitals. The indications for the procedure were a cytologic/histologic discrepancy, unsatisfactory colposcopic evaluation, positive endocervical curettage or exclusion of invasion. RESULTS: Severe thermal artifact rendered the LEEP specimens uninterpretable in 4.4% of cases. A median number of two passes were required for LEEP excision of the transformation zone. The number of passes correlated with the amount of thermal artifact detected (P = .034). Regarding recurrence patterns, normal follow-up cervical cytology was similar for both groups: 96.7% in the LEEP group vs. 100% in the cold knife conization group. CONCLUSION: We conclude that LEEP is an acceptable diagnostic alternative to traditional cold knife conization. Thermal artifact remains a disadvantage that can be minimized by limiting the number of passes required to obtain a complete specimen.  相似文献

Forty thousand consecutive cytologic smears and subsequent diagnostic procedures resulted in the diagnosis of 41 carcinomas in situ, 35 microinvasive and invasive carcinomas, and 24 severe dysplasias for a yield of significant neoplasia of one lesion per 400 Papanicolaou smears. Twenty-five of the carcinomas in situ and microinvasive and invasive carcinomas were diagnosed in patients with atypical smears indicating that all patients with persistent atypical smears require evaluation by tissue examination. Seventy-eight percent of the 119 patients subjected to conization either had carcinoma in situ, microinvasive and invasive carcinoma, or significant cervical dysplasia. Post-operative complications following conization were negligible. In addition there were no postconization deleterious effects on three concurrent and nine subsequent pregnancies. A history of gonorrhea places a patient at a higher risk of developing cervical carcinoma. Annual performance of cytologic smear evaluation is indicated in all sexually active women and in all virginal women over 20 years of age.  相似文献

The in situ polymerase chain reaction (PCR) is a technique that has important applications in the diagnosis of viral and bacterial diseases. This study investigated an in situ PCR assay established to detect the presence of Chlamydia trachomatis in endocervical swabs. In addition, histological sections of endocervical squamous cell carcinoma were analyzed because previous studies had revealed a significant association with C. trachomatis. A total of 20 cervical neoplasms (squamous cell carcinoma in situ; n = 10; invasive squamous cell carcinoma; n = 10) and endocervical smears taken from five patients with and without inflammatory changes were analyzed by conventional PCR. Chlamydial DNA was found in 10 histological samples (six carcinomas in situ, four invasive carcinomas) and in one endocervical swab from a patient with known C. trachomatis infection. Positive specimens were used for establishing an in situ PCR assay (IS-PCR). After IS-PCR, these samples showed dense cytoplasmic staining of endocervical cells (smears) and non-neoplastic epithelial cells (cervical neoplasms). The other tumor samples and smears did not demonstrate positive PCR reaction. The results indicate that in situ PCR is an effective technique for localizing C. trachomatis in target cells because IS-PCR detection of chlamydial DNA correlated with histological and cytological features.  相似文献

One hundred nine of 735 patients (14.8%) referred for colposcopic evaluation had "unsatisfactory" examinations. Of 108 women 40 years of age or over, 81 had unsatisfactory examinations (45%) as compared with 28 of 555 women under 40 (5%) (p less than 0.001). Thirty-five of the 109 patients with unsatisfactory examinations (32%) had had prior cautery or conization as compared with 141 of 626 in the "satisfactory" group (22.5%) (p less than 0.04). Seventy-three of the 99 patients on whom follow-up information was obtained had cervical conization biopsies for final diagnoses. Correlation with previously performed endocervical curettage and colposcopically directed biopsies was poor. Careful correlation of cytology, colposcopy and histopathology is necessary to achieve optimal results in the management of patients with unsatisfactory examinations. Diagnostic conization continues to play an important role in the management of patients with abnormal cervical cytology.  相似文献

The cytologic features of squamous cell carcinoma in situ with endocervical gland involvement have been described in cervical smears. We evaluated the presence of two types of cellular fragments in 43 cervical smears of high grade squamous intraepithelial lesions (HGSIL) to assess their ability to predict glandular involvement by HGSIL in subsequent cone biopsies. An endocervical brush was used to obtain all endocervical specimens. Of 16 cases without glandular involvement, fragments were present in 13 smears. Of 27 cases with glandular involvement, fragments were absent in 11 smears. No statistical association was identified between the presence of abnormal cellular fragments on cervical smears of HGSIL and endocervical gland involvement on cone biopsies.  相似文献

In gynecologic cytology, different reporting schemes suggest mentioning the presence of endocervical cells or asking for a statement on adequacy. We were interested in the question whether our data could provide a possible basis for discussing a sampling technique with smear takers. At the time of writing, in all cases, both the presence of endocervical cells and hysterectomy are recorded in our laboratory information system. Most smears are taken with cotton swabs, but the sampling technique is often modified according to the clinical situation. In a series of 20,471 cervical/vaginal smears, 2,152 (10.5%) were taken from hysterectomy patients. Among the non-hysterectomy patients, endocervical cells were found in 65% of the cases. Typically, there was a lower frequency of endocervical cells in smears stemming from older women. The frequency decreased from a maximum of 75% in the age group of 40-44 years to 45% in the age group of 65-69 years. With regard to the smear takers, some differences were evident, with age distribution and frequency of hysterectomy being different among the smear takers. In a setting where many smears of hysterectomized patients are examined by cytology, good data quality is required to evaluate the sampling techniques of different smear takers. The age dependence of endocervical cell yield is confirmed. Different age distribution of the patients from different smear takers suggests that the percentage of smears showing endocervical cells cannot be considered an optimal estimator.  相似文献

OBJECTIVE: To determine the significance of an atypical squamous cells of undetermined significance (ASCUS) diagnosis in patients 18 years or younger. STUDY DESIGN: From June 1994 to June 1995, 630 cervicovaginal smears were performed on patients 18 years or younger (mean age 16.4, range 14-18) at University Hospitals of Cleveland. Of these patients, 69 (10.9%) were diagnosed with ASCUS or ASCUS with a qualifying statement. Follow-up cervicovaginal smears, biopsies and charts were reviewed for a 12-18-month period following the initial diagnosis of ASCUS. RESULTS: The study population was sexually active: 63% were gravid, 21% were multigravid, 68% had a history of sexually transmitted diseases (STDs), and 32% had multiple STDs. Follow-up cervicovaginal smears or biopsies were obtained on 46 patients (32 cervicovaginal smears and 14 biopsies/endocervical curettage cases). Mild to moderate dysplasia was identified in 21.6% of patients (10.8% on cervicovaginal smears and 10.8% on biopsies), and a repeat diagnosis of ASCUS was given in 37%. In patients with a repeat diagnosis of ASCUS, a follow-up cervicovaginal smear or biopsy revealed dysplasia in an additional 13%. The overall rate of dysplasia was 34.7%. CONCLUSION: Regardless of age, the diagnosis of ASCUS in a sexually active patient population has significant implications. Furthermore, we recommend that these patients be managed the same way as high-risk adult patients.  相似文献

BACKGROUND AND OBJECTIVE: Minimal conization with carbon dioxide laser (CO2) for safe diagnosis and treatment of cervical intraepithelial neoplasia (CIN) 1-3 has been utilized for 15 years. To evaluate the results of 15 years' follow-up. STUDY DESIGN/MATERIALS AND METHODS: Clinical prospective study: 2,903 non-pregnant women whose cervicovaginal smear revealed CIN 1-3, confirmed by colposcopy, were referred for minimal conization treatment (LMC). This outpatient free-hand excision is performed under local anesthesia with a 60-W continuous laser beam focused to a 0.1-mm spot size, giving a power density of 165,000 W/cm2. Adjuvant cervical curettage is done routinely. RESULTS: Complications after the procedure were insignificant. Histopathological investigations revealed invasive carcinoma in 1.2% of the minicones. The primary cure rate was 96.1%. In the life table analysis of the patients the cumulative risk of recurrence for all forms of CIN was 0.89% at year 5, 1.36% at year 10, and 3.02% at year 15. There was no sudden onset carcinoma during the follow-up period. CONCLUSION: Minimal conization is a safe, effective treatment for CIN and early forms of microinvasive carcinoma. Invasive carcinoma can be detected early and should be treated without delay. The cumulative risk of developing new CIN is 3.02% at year 15 and there is no risk of sudden-onset invasive carcinoma following this procedure.  相似文献

Two hundred twenty-two women undergoing incidental diagnostic dilation and curettage (D&C) at the time of elective laparoscopic tubal ligation were studied retrospectively to ascertain if the risks of a D&C were warranted in a group of young, healthy women with a low risk of endometrial pathology. The endometrial sampling was associated with five uterine perforations and one readmission for bleeding and did not uncover any significant pathology in women under 35. The endocervical curettings did yield pathology of some clinical significance in women of all ages. The risk of uterine perforation was significantly higher in women who were < 15 weeks postpartum. We conclude that in a population of asymptomatic women under the age of 35, a diagnostic D&C is not indicated at the time of elective laparoscopic tubal ligation.  相似文献

Colposcopic examination and biopsy were used to assess 123 pregnant patients presenting with abnormal cervical smears. Eighty-seven per cent were 30 years of age or less and 95 (77 per cent) had had one or no previous children. Two patients were found to have microinvasive carcinoma and, in an additional 95 patients, either severe dysplasia or carcinoma in situ was present. Fifty-five patients (45 per cent) had subsequent conization or hysterectomy and in no instance was the histological diagnosis more serious than that anticipated from the colposcopic evaluation. Only three patients (1-6 per cent) had a cone biopsy during pregnancy; only one minor complication occurred. Colposcopic examination is the choice method of evaluating patients with abnormal cervical smears in pregnancy.  相似文献

One hundred and sixty-eight cases of cervical conization were performed for cervical intraepithelial neoplasia (CIN) in a 32-month study. The indications for conization were unsatisfactory colposcopic finding, abnormal epithelium that extended into the endocervical canal, a microinvasive cervical cancer, and significant discrepancy among cytology, colposcopy, and/or punch biopsy histology. In the early period of the study, conization was done by the cold-knife method (N = 107), whereas loop diathermy was used in the latter part of the study (N = 61). Both groups were similar in terms of age, indications for conization, and size of cervical cone specimens. Loop diathermy conization was done in a significantly shorter time (5.7 +/- 1.8 minute vs 15.2 +/- 6.1 minute)(P < 0.05) than cold-knife conization. However, the difference in the postoperative complications between loop diathermy(3.0%) and cold-knife conization(4.7%) was not significant. The incidence rate of residual CIN III lesions in the subsequent hysterectomy specimens, found by histological documentation on these specimens was 25.0 and 26.1 percent after loop diathermy and cold-knife conization respectively. These results suggest that loop diathermy is much easier to perform and a more time-conserving treatment modality than cold-knife conization in the management of patients with cervical intraepithelial neoplasia.  相似文献

A series of 12 adenoid basal carcinomas and three adenoid basal hyperplasias of the cervix were analyzed. The ages of the patients with adenoid basal carcinoma ranged from 30 to 91 years with a mean of 71 years. Pap smear results for 11 of 12 (92%) were abnormal. Almost all patients were asymptomatic. None had a gross cervical tumor. All tumors had typical histologic features of adenoid basal carcinoma, with various degrees of squamous differentiation. Depth of tumor invasion ranged from 2 mm to 10 mm (mean, 4.3 mm; median, 3.7 mm), exceeding 3 mm in six tumors (50%). Tumor volume was >500 mm3 in four tumors (33%). An associated neoplastic squamous lesion was present in 92% of patients, including high-grade cervical intraepithelial neoplasia in 10 cases and microinvasive squamous cell carcinoma in one. Treatment was predominantly surgical, usually after some form of cervical conization; conization alone was performed in three patients. Lymph nodes were removed in five patients; none of 104 nodes had metastases. No recurrence of tumor developed in any patient. Nine patients were alive without disease after 4 to 82 months (mean, 30 months), and three died without disease after 24, 63, and 87 months. The three patients with adenoid basal hyperplasia also were asymptomatic and did not have a gross cervical lesion. Pap smear results for two patients were abnormal. The adenoid basal hyperplasias were incidental, very superficial lesions that resembled small adenoid basal carcinomas. Generally, they were attached to the squamous or endocervical mucosal epithelium; all were less than 0.5 mm in depth. Treatment was hysterectomy in one patient and conization in two. Follow-up was short but uneventful. Our findings, together with those previously reported, indicate (1) adenoid basal carcinoma with typical histologic features is not a malignant neoplasm in that it typically presents in asymptomatic women, usually is discovered after an abnormal Pap smear result due to cervical intraepithelial neoplasia, does not produce a grossly visible lesion, has never metastasized to regional lymph nodes or elsewhere, and has never itself caused death; (2) rare, histologically atypical tumors with distinctly malignant features should not be regarded as adenoid basal carcinoma; and (3) adenoid basal hyperplasia probably is a small adenoid basal carcinoma. We propose the term "adenoid basal epithelioma" to replace adenoid basal carcinoma and adenoid basal hyperplasia, because it better describes the clinicopathologic features of these distinctive lesions and their excellent prognosis and may reduce the likelihood of unnecessarily aggressive treatment.  相似文献

OBJECTIVE: To determine whether the order of cell collection, endocervical or ectocervical cells first, has an effect on the quality of the Papanicolaou smear. METHODS: One thousand smears were obtained using an Ayre spatula and an endocervical brush. In 500 cases the endocervical brush was used first, and in 500 cases the spatula was used first. All Papanicolaou smears were collected by resident physicians in our university hospital gynecologic clinics. A smear was considered limited for interpretation for the following reasons: 1) lack of endocervical component, 2) obscured by blood, 3) obscured by inflammation, 4) drying artifact, and 5) too thick. RESULTS: The brush-first group had 405 (81%) adequate smears compared with 410 (82%) adequate smears in the spatula-first group. More smears were obscured by blood when the brush was used first (22 or 4.4% compared with three or 0.6%, P < .001). No endocervical component (ie, metaplastic cells, endocervical cells, or mucus) was found in 29 (5.8%) smears from the brush-first group compared with 45 (9.0%) of the spatula-first group, an insignificant difference. More squamous intraepithelial lesions were found when the spatula was used first (55 or 11% compared with 35 or 7.0%, P < .05). CONCLUSION: The quality of the Papanicolaou smear can be improved by using the Ayre spatula first followed by the endocervical brush. Fewer smears will be obscured by blood, which could result in more squamous intraepithelial lesions being detected.  相似文献

ISSUES: The colposcope was developed in 1925 and is well established in clinical gynecologic practice for defining and delineating cytologically detected lesions mainly of the cervix but also the vagina and vulva. Additionally, various endoscopic procedures in gastroenterology, pulmonary and urologic lesions enhance the cytologic detection and histologic verification of precancerous and cancerous lesions. The cost-effectiveness of all these devices and their applicability, particularly in countries with a limited health budget, is a major issue. This task force considered aspects of the present state of the art and the challenges in the 21st century. CONSENSUS POSITION: Automated cytology can interface with colposcopic examination in a number of significant ways. Automated cytologic analysis of conventional cervical smears can potentially direct colposcopic examination by predicting the nature of a lesion, assist in determining which patients should receive colposcopy and, in some settings, thereby reduce the number of colposcopies. Potentially, various combinations of automated cytology and colposcopy may be used to generate screening protocols that might result in more effective and inexpensive screening. The role of cervicography, or high-resolution cervical photography, as a screening device remains to be defined. Sensitivity for high grade lesions is generally no greater than that in cytology, and specificity appears lower. The interpretation of cervical photographs in triage of mildly abnormal cytology may prove to be useful in countries with established cytology programs. In areas of the world where cytology screening programs are not in place, the interpretation of cervical photographs may have its most dramatic effect. Cost-effectiveness analyses are needed. There are, at present, insufficient data for the evaluation of speculoscopy, a procedure using chemiluminescent illumination of the cervix for visualization of acetowhite areas. Basic training in colposcopy should be integrated into the residency programs of obstetrics and gynecology. Criteria for the adequate training of colposcopists should be developed. Continuing education programs in colposcopy should be developed when they are not already in existence. The cost-effectiveness of integrating colposcopy as a primary screening technique should be evaluated. Following a high-grade squamous intraepithelial lesion (HSIL) cytology result, colposcopically directed punch biopsy should be taken with or without endocervical curettage. This generally should precede the loop electrosurgical excision procedure (LEEP); however, in certain circumstances direct LEEP may be indicated. LEEP under colposcopic vision is an efficient way to treat an HSIL lesion of the cervix because the histologic extent and margins can be determined, unlike with laser surgery or cryosurgery. It is also more cost-effective than cold knife conization because general anesthesia and an operating room are unnecessary. Following LEEP, the endocervical canal should be examined colposcopically for any evidence of involvement. Lesions in the endocervix can then be removed with a different-shaped loop. Further research into Raman spectroscopy as a diagnostic aid in cervical pathology is needed, as is the use of micrococolpohysteroscopy for in vivo cytologic analyses, especially of the endocervical canal and transformation zone. Hysteroscopy is the most direct method for the diagnosis and treatment of intrauterine diseases. Hysteroscopic endometrial biopsy is more accurate than conventional biopsy methods. Cervical invasion of endometrial cancer can be detected by hysteroscopy. The depth of invasion, however, is more accurately determined by magnetic resonance imaging or computed tomography. ONGOING ISSUES: Many topics for ongoing research and/or implementation are mentioned under "Consensus Position," above. (ABSTRACT TRUNCATED)  相似文献

The objective of this study was to evaluate the incidence of residual disease and the presence of human papillomavirus (HPV) after conization. Data on 53 patients with carcinoma in situ or microinvasive carcinoma who underwent hysterectomy less than 2 months after conization were examined. Seven of 53 patients (13%) had positive margins. In 4 of these 7 patients (57%), residual disease was found in the postconization hysterectomy specimen. Two of 46 patients (4%) with negative margins also had residual disease. HPV DNA was detected by PCR in 27 of 53 conization specimens and in 2 postconization hysterectomy specimens. Of 2 patients, 1 did not have residual disease. Residual disease could be present even with a negative conization margin, and HPV DNA may be found in a histologically normal cervix after conization.  相似文献

After reviewing the charts of patients at the Tulane Unit of Obstetrics and Gynecology of Charity Hospital between the years 1950 and 1970, 25 patients were noted to have carcinoma in situ of the cervix uteri associated with pregnancy. Twenty-two patients had positive Papanicolaou smears. Subsequently, 20 patients had conization of the cervix uteri to exclude an invasive lesion. Vaginal delivery was accomplished in 17 of the patients. After complete re-evaluation, definite treatment was done six to eight weeks post partum, and there were no recurrences or deaths from the disease.  相似文献

Cervical involvement is one of the major prognostic factors in carcinoma of the endometrium confined to the uterus. The purpose of this study was to determine whether intrauterine ultrasound with a high-frequency miniature probe can depict the degree of cervical involvement of the disease. Thirty-two women with endometrial carcinoma underwent preoperative transvaginal and intrauterine sonography. By both scans, the degree of cervical involvement was prospectively evaluated. Sonograms were compared with the findings from histologic examination. Intrauterine sonography was completed in 30 of the 32 patients. In these 30 patients, the degree of cervical involvement (none, endocervical gland, or cervical stroma) based on transvaginal scan was correct in 23 cases (77%), and that based on intrauterine scan was correct in 26 cases (87%). Three tumors with endocervical glandular involvement were correctly diagnosed by intrauterine sonography, whereas they were incorrectly diagnosed by transvaginal scan. The specificity and positive predictive value of intrauterine sonography for the assessment of the presence of cervical stromal invasion are 100% (26/26 and 3/3, respectively). Although this study is preliminary, our experience with intrauterine sonography shows that it has potential for assessing cervical stromal invasion in endometrial carcinoma.  相似文献
