Adenocarcinoma in situ of the uterine cervix.

OBJECTIVE: To assess the diagnostic accuracy of cervical conization in women with adenocarcinoma in situ and to determine whether a select group of women could be managed by conization alone without hysterectomy. METHODS: We retrospectively reviewed 40 cases of cervical adenocarcinoma in situ diagnosed on cervical conization. RESULTS: Cervical conization revealed adenocarcinoma in situ alone in 15 women. Twenty-five women had adenocarcinoma in situ coexisting with squamous dysplasia (23) or microinvasive squamous cell carcinoma (two). Twenty-two women underwent hysterectomy after cone biopsy. Adenocarcinoma in situ was detected in the hysterectomy specimen in one of 12 women with uninvolved cone margins, versus seven of ten women with involved margins (P = .006); two of these seven women also had foci of invasive adenocarcinoma in the hysterectomy specimen. Conization was the only treatment for 18 selected women with adenocarcinoma in situ and uninvolved margins; all were relapse-free after a median interval of 3 years (range 1.5-5). CONCLUSIONS: Women with cervical adenocarcinoma in situ diagnosed by conization who have positive margins are at high risk of residual adenocarcinoma in situ and moderate risk of occult invasive adenocarcinoma; expectant management is not warranted. However, a cone biopsy with uninvolved margins can reliably guide subsequent therapy. Selected young women who desire preservation of fertility and have uninvolved margins probably can be managed by conization alone, but further study is required to establish the safety of this approach.

Further study of the management of cervical adenocarcinoma in situ.

OBJECTIVE: The objective of this study was to study further the management of cervical adenocarcinoma in situ (AIS) with particular regard to the results of conservative management without hysterectomy and the use of large loop excision of the transformation zone (LLETZ). METHODS: Based upon the files of the Pathology Department at the Cleveland Clinic Foundation, recently encountered AIS patients were combined with patients from a previous study that ended in 1994. Charts and clinical materials were retrospectively reviewed and abstracted. RESULTS: Fifty-two patients were identified for a combined study group of 98 patients. The mean age was 37 years. Fifty-two percent were identified due to abnormal squamous elements on a Pap smear and 43% due to abnormal glandular cells. In patients treated with hysterectomy, 67% were found to have residual disease following conization with positive margins including 3 patients with invasive cancer. Among all patients, LLETZ was associated with a positive margin rate of 57.1% vs 27.3% with cold knife conization (CKC) (chi(2), P = 0.008). Among patients treated conservatively with conization, the rates of positive margins were 40.0 and 20.0%, respectively, for LLETZ and CKC (chi(2), P = 0.11); 9.5% of conservatively managed patients with negative initial conization margins eventually had recurrent AIS. CONCLUSION: Cold knife conization is the preferred method of management for cervical AIS patients selecting conservative treatment. Despite initial conization margins being uninvolved, such patients have an approximate risk of 10% for recurrent AIS.

Transvaginal ultrasonography in the prediction of preterm birth after treatment for cervical intraepithelial neoplasia.

OBJECTIVE: To estimate whether cervical length measured by transvaginal ultrasonography in women having had loop electrosurgical excision procedure (LEEP), cold knife conization, or cryotherapy predicts spontaneous preterm birth. METHODS: Women with a history of LEEP, cold knife conization, or cryotherapy and who were subsequently pregnant with singleton gestations were prospectively compared with both a low-risk control group and women with previous spontaneous preterm birth. A transvaginal ultrasonogram measuring cervical length was performed at 24 to 30 weeks of gestation. Primary outcomes included cervical length and spontaneous preterm birth less than 37 weeks. Secondary outcomes were spontaneous preterm birth less than 34 weeks, low birth weight, and maternal and neonatal outcomes. RESULTS: Women with previous LEEP (N = 75), cold knife conization (N = 21), and cryotherapy (N = 36) had shorter cervical lengths (3.54, 3.69, and 3.75 cm respectively) than the low-risk control group (N = 81, 4.21 cm) (P < .001, P = .03, P = .02 respectively) and similar lengths to women with a previous spontaneous preterm birth (N = 63, 3.78 cm). Loop electrosurgical excision procedure and cold knife conization, but not cryotherapy, were associated with spontaneous preterm birth less than 37 weeks (odds ratio 3.45, 95% confidence interval 1.28-10.00, P = .02; and odds ratio 2.63, 95% confidence interval 1.28-5.56, P = .009, respectively). Using a cutoff of 3.0 cm, transvaginal ultrasonography had a positive predictive value of 53.8% and negative predictive value of 95.2% for spontaneous preterm birth less than 37 weeks in women with LEEP. CONCLUSION: Women with a history of LEEP, cold knife conization, and cryotherapy all independently have shorter cervical lengths than low-risk controls and similar lengths to women with previous spontaneous preterm birth. Loop electrosurgical excision procedure and cold knife conization are associated with spontaneous preterm birth less than 37 weeks, and transvaginal ultrasonography predicts preterm birth in women who have had LEEP. LEVEL OF EVIDENCE: II-2.

High-grade cervical intraepithelial neoplasia (CIN) in pregnancy: clinicotherapeutic management.

UNLABELLED: An increasing incidence of cervical intraepithelial neoplasia (CIN) among young women has been noticed in recent years. For this reason pregnancy might represent a peculiar opportunity to undergo cytocolposcopic examination for those women who do not take part in a screening program for cervical carcinoma. Diagnosis of CIN during pregnancy poses the question of the management of this disease and particularly of whether it is better to treat the lesion or not during pregnancy. To contribute to the solution of this issue we initiated a study on the management of high-grade CIN in pregnancy. MATERIAL AND METHODS: Five hundred and seventy-one pregnant women underwent cytologic, colposcopic and, when necessary, histologic examination. Those in whom a CIN was discovered in the first four months of gestation underwent laser conization. When the diagnosis of CIN was made after the sixteenth week of gestation, cytocolposcopic monitoring was performed every eighth week during pregnancy and two months after childbirth. Laser conization was performed under colposcopic guidance in the outpatient setting in all cases. All treated patients were submitted to cytologic, colposcopic and, if necessary, histologic examination every third month in the first year after treatment, every sixth month in the second year and yearly from the third year onwards. RESULTS: In 14 (2.4%) of the 571 examined women a CIN III was discovered, 6 of which associated with a human papilloma virus (HPV) infection. Of these, 8 patients, whose diagnosis was made within the sixteenth week of pregnancy, underwent laser conization. In one case a minor hemorrhage occurred during treatment. Two patients reported minor bleeding up to ten days after treatment. No major hemorrhages or cervical stenosis were observed. Histologic examination of the cones confirmed the preoperative diagnosis based on cervical biopsies and the lesion was entirely removed by conization in all cases. Seven of the 8 patients who underwent laser conization during pregnancy had a spontaneous delivery at term. The remaining patient, who had had a previous cesarean section, was again delivered by cesarean section. All treated patients were cured after the first-year follow-up visit. In 6 patients CIN was diagnosed after the sixteenth week of pregnancy. These women underwent cytocolposcopic examination every eighth week during pregnancy and two months after delivery, when the cervical changes associated with gestation had disappeared. Four of these patients showed persistence of CIN at postpartum follow-up and therefore underwent laser conization. In two patients spontaneous regression of the lesion was observed. In no case did progression to invasive carcinoma occur. CONCLUSIONS: Given the increasing incidence of CIN in young women, the beginning of pregnancy may represent a peculiar opportunity for all pregnant women who do not take part in cervical screening programs to undergo a cytocolposcopic examination. In case of a diagnosis of high-grade CIN within the first 16 weeks of pregnancy, a conservative excisional treatment, which does not expose the pregnancy to any risk, should be carried out in order to confirm the intraepithelial localization of the lesion.

The clinical outcome of patients with stage Ia1 and Ia2 squamous cell carcinoma of the uterine cervix: a Cooperation Task Force (CTF) study.

PURPOSE OF INVESTIGATION: The objective of this retrospective multicenter study was to assess the clinical outcome of patients with microinvasive squamous cell carcinoma of the uterine cervix. METHODS: The hospital records of 166 patients with microinvasive squamous cell carcinoma of the uterine cervix were reviewed. All cases were retrospectively staged according the 1994 International Federation of Gynecology and Obstetrics (FIGO) nomenclature. One hundred and forty-three cases were in Stage Ia1 and 23 in Stage Ia2 disease. Surgery consisted of conization alone in 30 (18.1%) patients, total hysterectomy in 82 (49.4%), and radical hysterectomy in 54 (32.5%). All patients in whom conization was the definite treatment had Stage Ia1 disease and had cone margins negative for intraepithelial or invasive lesions. RESULTS: None of the 67 patients submitted to pelvic lymphadenectomy had histologically proven metastatic lymph nodes. Of the 166 patients, eight (4.8%) had an intraepithelial recurrence and four (2.4%) had an invasive recurrence. With regard to FIGO substage, disease recurred in nine (6.3%) out of 143 patients with Stage Ia1 and three (13.0%) out of 23 with Stage Ia2 cervical cancer. With regard to type of surgery, disease recurred in three (10.0%) out of the patients treated with conization alone, four (4.9%) out those who underwent total hysterectomy, and five (9.3%) out of those who underwent radical hysterectomy. It is worth noting that none of the 30 patients treated with conization alone had recurrent invasive cancer after a median follow-up of 45 months. However three (10%) of these patients developed a cervical intraepithelial neoplasia (CIN) III after 16, 33, and 94 months, respectively, from conization. CONCLUSIONS: Conization can represent the definite treatment for patients with Stage Ia1 squamous cell cervical cancer, if cone margins and apex are disease-free. For patients with Stage Ia2 cervical cancer extrafascial hysterectomy with pelvic lymphadenectomy might be an adequate standard therapy, although the need for lymph node dissection is questionable.

Colposcopic directed biopsy in the management of abnormal pap smear at Phramongkutklao Hospital.

OBJECTIVE: To evaluate agreement in pathologic diagnosis of tissue obtained by colposcopic directed biopsy (CDB) and conization or total abdominal hysterectomy (TAH) in the diagnosis of cervical intraepithelial neoplasia (CIN). MATERIAL AND METHOD: Medical records of women with abnormal cervical cytology referred for colposcopic examination from January 1, 1999 to December 31, 2003 were reviewed. Agreement in diagnosis of CIN in tissue obtained by CDB and tissue obtained by conization or TAH is defined as not more than one level of CIN disparity. RESULTS: Agreement between pathologic diagnosis of tissue from CDB and tissue from conization or TAH is 67.1% with a 95% confidence interval of 57-77%. Six cases of invasive cancer were not diagnosed from CDB but subsequently diagnosed from conization. CONCLUSION: Agreement between pathologic diagnosis of tissue obtained from CDB and tissue from conization or TAH in the present study was too low to accept CDB as a diagnostic modality for CIN in selected cases. Conization should be performed in these cases after diagnosis of CIN is made by CDB.

Microinvasive adenocarcinoma of the cervix: a clinicopathologic study of 77 women.

OBJECTIVE: To prove that microinvasive adenocarcinoma of the cervix exists and, like its squamous counterpart, carries an excellent prognosis. METHODS: Seventy-seven women with microinvasive adenocarcinoma of the cervix were seen from 1971 to 1995. Microinvasion was defined as depth of invasion or tumor thickness of at most 5 mm. Microscopic assessment was made on punch biopsies, serially sectioned conization specimens, and extensively sampled hysterectomy specimens. RESULTS: Most of the women had abnormal Papanicolaou smears. We made definitive diagnoses on conization specimens in 49 women, hysterectomy specimens in 22, and colposcopically directed punch biopsies in six (three being no residual disease in the subsequent conization-hysterectomy specimens). The length of microinvasive adenocarcinomas ranged from 0.8 to 21 mm, and the volume was between 3 and 1000 mm. The tumors were multicentric in 21 cases, but no true "skip" lesions were found. Overall, 58 cold-knife conizations were performed: the margins were free in 39 cases, involved in 18, and inconclusive in one. The one loop conization had involved margins. Definitive therapy included cold-knife conization in 16 women, combined with pelvic-node dissection in four. In the remainder of the women, we performed some type of hysterectomy. None of the 26 women who had radical hysterectomy had parametrial spread, and none of the 48 who had pelvic-node dissection or the 23 in whom one or both adnexa were removed had metastases. There have been two "recurrences" to date; one was an adenocarcinoma and the other a squamous cell carcinoma, both at the vault. CONCLUSION: Microinvasive adenocarcinoma of the cervix is a clinicopathologic entity that appears to have the same prognosis, and should be treated in the same way, as its squamous counterpart.

[Diagnosis and treatment of cervical dysplasia. Report of 42 cases].

The authors present a retrospective study of 42 cases of conization carried out between January 1987 and October 1989 in the Department of Gynaecology 1 of Dupuytren University Hospital in Limoges. The average age of the population was 42 years and 7 months, with an average parity of 1.9 children per woman. Conization was carried out using either a cold knife (37 cases) or an electric knife (5 cases). Complications consisted of 4 stenoses, 2 secondary haemorrhages and 1 perineal burn. 4 microinvasive cancers, 7 CIN III, 10 CIN II, 4 CIN I and 3 pieces of tissue free from any dysplastic lesion were found on histological examination of the conization tissue. 17 patients (40.4%) had flat condylomas. There was perfect agreement between the diagnoses from the smears and biopsies in 82.1 p. cent of cases; there was 57.1 p. cent agreement when the smear result was compared with the histological study of the conization tissue, and 39.2 p. cent agreement when the latter was compared with biopsy results. On the other hand, false diagnosis due to overevaluation of the severity of the dysplasia was predominant using the least invasive examination (42.8 p. cent when comparing the smear results with those from the study of conization tissue, and 39.2% for biopsies with respect to the conizations). According to the authors, the therapeutic strategy to be used in treating dysplasia must take the severity of the dysplasia, the presence of infection due to HPV and its serotyping, the location and size of the dysplasia, the visibility of the endo-exocol junction line and the psychological context of the patient into consideration.

Fertility sparing treatment for in situ and early invasive adenocarcinoma of the cervix.

OBJECTIVE: To explore the outcome and long-term follow-up of fertility sparing surgery for cervical adenocarcinoma in situ and early invasive adenocarcinoma. METHODS: Between 1985 and 1996, all women with adenocarcinoma in situ (AIS) and stage I adenocarcinoma were identified. Data were abstracted from clinical records and pathology reviewed. RESULTS: One hundred thirty three women with stage I adenocarcinoma of the cervix were treated. Twenty subjects met the criteria for International Federation of Gynecology and Obstetrics stage IA1 lesions. Fourteen subjects were treated with radical hysterectomy, whereas two were treated with simple hysterectomy. Because of the desire to preserve fertility, four women with adenocarcinoma were treated with cervical conization alone, and three women have gone on to deliver viable infants. Forty-two women with adenocarcinoma in situ were identified, of whom 20 were treated with fertility sparing surgery (conization). Five women treated with conization had positive margins recurring in two, and one developed an invasive adenocarcinoma 5 years after conization. None of the women with adenocarcinoma treated with cervical conization have developed recurrent disease after a median follow-up of 48 months. Cone margin status was predictive of residual disease at hysterectomy. CONCLUSION: Women with adenocarcinoma in situ and negative margins may be treated with conservative, fertility sparing surgery. Education is essential regarding the risks of residual/recurrent disease because subjects can develop lethal recurrent disease. The fertility sparing management of invasive stage IA1 adenocarcinoma of the uterine cervix may also be entertained among women who desire future fertility and have negative margins of resection.

Loop-cone cerclage in pregnancy: a 5-year review.

OBJECTIVE: The purpose of this study was to evaluate the efficacy and outcomes of patients undergoing conization utilizing a technique of loop-cone cerclage when a diagnostic cone biopsy was required in pregnancy. METHODS: All loop conizations between 1997 and 2001 were reviewed; 15 patients were identified who underwent cone- cerclage with 13 medical records completely available for review. Abstracted data included age, parity, pap smears prior to and during pregnancy, and histology obtained during colposcopy. The operative time for the procedure, estimated blood loss, complications, pathology of loop specimen, and pregnancy outcomes were recorded. RESULTS: Thirteen charts were available for complete review. The mean operating time was 22 min; 11 patients had less than 50 cc blood loss and two patients had a 250 cc blood loss. The median age was 26.5, average parity was 2, and mean gestational age was 24.1 weeks. Six patients had abnormal pap smears prior to pregnancy, one woman had previously undergone colposcopy, and there was no documentation of previous pap smears in six patients. During pregnancy, on pap smear, nine patients had HSIL, three patients had ASCUS/LSIL, and one patient had adenocarcinoma. Thirteen patients underwent colposcopy and biopsy; eight patients had the question of invasive disease, five patients had endocervical glandular involvement with carcinoma in situ, which were the indications for conization. There were no intraoperative or late postoperative complications. All patients delivered at term. CONCLUSIONS: While the need for conization during pregnancy is rare, there are indications when it is necessary. Loop-cone cerclage is a safe method for performing diagnostic and therapeutic conization during pregnancy.

[Therapy for cervical intraepithelial neoplasia and fertility].

BACKGROUND: We reviewed the case records of patients of childbearing age treated with various types of surgical techniques for cervical intraepithelial neoplasia (CIN) to determine the impact of surgical treatment on their fertility. METHODS: Between 1983 and 1997 a total of 486 women with CIN received surgical treatment at out unit. Laser vaporization was used in 196 cases, cold-knife conization in 163 and REP in 127. The outcome of the various treatments was then compared. RESULTS: Independent of the surgical technique used, the percentage of pregnancies achieved after surgery was high: 93.33 and 96.66% of patients treated with laser vaporization and REP, respectively, and 87.69% of those who received cold-knife conization. The differences did not reach statistical significance nor were significant differences observed in the number of abortions or in the method of birth delivery (spontaneous, Cesarean section). However, a higher percentage of premature births was noted among women who received cold-knife conization (31.57%), which was statistically significant in the comparison among the three groups. CONCLUSIONS: The results from our study indicated which techniques for the treatment of CIN may be preferable. Compared with the other two techniques, cold-knife conization bears higher costs (hospitalization, general anesthesia) and has been superceded by laser vaporization and REP as evaluated in this series. When cold-knife conization must be used, cerclage of the cervix uteri should be performed in the event of future pregnancy. In contrast, laser vaporization and REP can be performed in an outpatient setting with local anesthesia. These techniques, because they are conservative, afford the advantages of complete lesion removal and maintenance of reproductive capability. Another important consideration is that REP is less costly and allows histological examination of the surgical specimen.

Squamous intraepithelial lesion-microinvasive carcinoma of the cervix during pregnancy.

OBJECTIVE: The objective of this work was to assess proper management of squamous intraepithelial lesion (SIL) and microinvasive carcinoma during and after pregnancy, to assess risks of punch biopsy and conization in pregnancy and to assess regression, persistence and risk of progression with low-grade (L) and high-grade (H) SIL. METHODS: We carried out a prospective study of 167 pregnant women from our colposcopic unit who were referred to us for abnormal cytological findings between 1997 and 2002. The diagnosis of precancerosis was verified in all of the women by punch biopsy, suspect microinvasive carcinoma needle or LETZ conization up to the 20th week of pregnancy. All women were followed-up during the pregnancy and 24 months after their deliveries. RESULTS: In 23 women with suspect early invasion we performed conization during the pregnancy (weeks 13-23). There were six cases (26.1%) of microinvasive carcinoma and 17 cases (73.9%) of HSIL. One pregnancy aborted two days after the conization. No other obstetrical complications were recorded and there were no premature deliveries. Sixty-two women with HSIL were only followed-up during their pregnancy. We observed complete regression of HSIL during the study in 14 patients (22.6%), regression to LSIL in 17 patients (27.4%), persistence in 25 patients (40.3%) and progression to microcarcinoma in six cases (9.7%). Eighty-two patients were followed up for LSIL. Complete regression of LSIL was observed during the study in 40 cases (48.8%), persistence in 24 cases (29.2%) and progression to HSIL in 18 cases (22.0%). CONCLUSION: For LSIL and HSIL during pregnancy the above follow-up is a sufficient and safe protocol. Suspect microinvasive carcinoma should be treated by conization, which is a safe procedure until the 24th week of pregnancy.

Cone biopsy causes cervical endometriosis and tubo-endometrioid metaplasia.

Cervices from 42 hysterectomies performed from 1 to 91 months (mean 12.2) following conization were re-examined in order to assess the possible effects of post-traumatic regeneration on the endocervix. Twenty-nine (69%) showed a continuum of abnormalities in which the shared finding was the presence of tubo-endometrioid glands, accompanied in many cases by varying amounts of endometrial-type stroma. Thus, 18 post-conization cervices (43%) showed endometriosis, and a further 11 cases (26%) contained tubo-endometrioid glands without demonstrable endometrial-type stroma. These abnormalities were situated at the healed cone biopsy site, either superficially within the new transformation zone and/or within the cone biopsy scar. Post-conization cervical endometriosis occurred from 2 to 91 months (mean 17.8) and tubo-endometrioid metaplasia 2-24 months (mean 11.0) after the cone biopsy. It is concluded that cervical endometriosis and tubo-endometrioid metaplasia are common complications of conization, and that they represent aberrant differentiation following injury. The demonstration of endometriosis and tubo-endometrioid metaplasia in 69% of post-conization cervices has implications for the interpretation of cervical biopsies and smears from this group of women.

[Radiosurgical treatment of cervical intraepithelial neoplasia].

In the present study we present our experience and data with loop electrosurgical excision procedures for the treatment of human papilloma virus (HPV)-associated lesions and intraepithelial neoplasia of the cervix. 58 patients underwent loop excision because of colposcopically suspect cervical lesions. In 78 cases cone biopsy (large loop excision of the transformation zone, LLETZ + partial resection of the cervical canal) was performed. In 80% of the loop excisions the lesions were removed with clear resection margins. Patients undergoing LLETZ conization were compared to patients who had a cold knife conization previously. The two groups were matched with regard to age, parity and histology. The cone specimen of patients with LLETZ conization revealed lesion-free margins in 93% compared to 87% in the group with cold knife conization. Operation time and duration of hospital stay were significantly shorter in the group of LLETZ conization. Loop electrosurgical excision procedures therefore represent an adequate method for the treatment of HPV-associated lesions and intraepithelial neoplasia of the cervix.

The diagnostic accuracy of combined colposcopy, cytology, and target biopsy of carcinoma in situ of the uterine cervix.

The results of cytology, colposcopy and target biopsy in 91 cases diagnosed by conization as uterine cervical carcinoma in situ and 39 cases diagnosed as microinvasive carcinoma were compared. Lesions limited to the ectocervix could be identified by colposcopy, and those identified as carcinoma in situ by cytology or target biopsy were all included in the group diagnosed as carcinoma in situ by conization. Among the 29 cases of carcinoma in situ limited to the ectocervix, 19 (66%) were similarly diagnosed by both cytology and target biopsy, allowing for us to avoid conization. For cases diagnosed as microinvasive carcinoma using target biopsy, conization must also be performed in order to determine the depth of invasion. Even in cases diagnosed as dysplasia or carcinoma in situ by target biopsy, when it is thought that the lesion may extend into the cervical canal or in cases where agreement with the cytological results is not found, conization is necessary.

[Study with serial sectioning of 312 preclinical cancers of the uterine cervix. Indications for selective treatment (author's transl)].

The authors have studied by step serial sectioning 312 cervix the most obtained by cold knife conization. They have studied too, the frequency of inadequate resection (i.e. non in sano conization) and clinically occult invasion according to the age of patients. Conization is adequate for the treatment of 70 per cent of women less than 30 years of age. But after 50 it is sufficient in only 22 per cent of the patients. Conization must be performed in most cases of grade III to V cervical smear (according to Papanicolaou's classification). The cervical cone must be studied by serial sectioning (every 500 microns). According to the result of this study the treatment must be selected : conization for in situ carcinoma resected in sano, simple hysterectomy for in situ carcinoma not resected in situ and Wertheim type operation for invasive carcinoma.

The suitable treatment for adenocarcinoma in situ of uterine cervix: a report of four cases.

Adenocarcinoma in situ (AIS) of the uterine cervix is a rare disease. Some authors suggested that conization is a suitable treatment for AIS as for squamous cell carcinoma in situ. However, others did not agree. Four cases of AIS, from 1984 to 1994, have been diagnosed in the Hospital of National Taiwan University. If the diagnosis of the conization specimen showed AIS, abdominal total hysterectomy was performed days thereafter. The remaining uterine cervix was checked by histopathology to determine whether it was free of cancer lesions. AIS lesions remained in the uterine cervix, as shown by conization in two cases. AIS is not like lesion as squamous cell carcinoma in situ lesion which is easy to be removed by conization. It is suggested that conization is not an adequate treatment for AIS, rather, a total hysterectomy should be performed.

The reliability of preconization diagnostic evaluation in patients with cervical intraepithelial neoplasia and microinvasive carcinoma.

The accuracy of preconization cytology and histology was evaluated in 536 patients undergoing combination laser conization. Exact agreement between cytology and cone diagnosis was observed in 41.8% of the patients. The lowest agreement, 13.6% was demonstrated in cytologic cervical intraepithelial neoplasia (CIN) I, the highest in cytologic CIN III, 64.3%. Concerning microinvasive disease, the positive predictive value of cytology was only 27.3%; the negative predictive value 94.6%. When cytology showed CIN II or worse, the cone biopsy showed CIN or invasive disease in 92.8%. Exact agreement between preconization histology and the cone biopsy was found in 59.5%. Highest agreement was observed in CIN III lesions, 67.1%, and the lowest agreement in CIN II lesions, 42.7%. When preconization showed CIN II, a higher grade of lesion was found in the cone biopsy in 29.1%. Cone biopsy revealed invasive disease in 38 cases. In 24 cases, invasive disease was not demonstrated prior to conization, corresponding totally to 4.7% of patients not suspected to have invasive disease prior to conization. Regarding invasive disease, the sensitivity of preconization histology was 36.8%, the positive predictive value 58.3%, and the negative predictive value 95.3%. Kappa statistics demonstrated rather low agreement between cone diagnoses and preconization diagnoses. These results confirm the potential risk of overlooking invasive disease by conventional preconization evaluation and demonstrate the need for excisional methods in the management of cervical intraepithelial neoplasia to provide a sufficient specimen for diagnostic purposes. Combined with the therapeutic results, combination laser conization was a reliable diagnostic and therapeutic method in the management of patients with CIN and microinvasive cancer of the cervix.
