Loop electrosurgical excision has largely replaced the ablative techniques for treatment of all grades of CIN. Its major advantage is that it produces a tissue specimen, which can be examined to ensure that invasive carcinoma is not present. Recent series have found unexpected microinvasive or invasive squamous lesions in 0.7% of loop specimens and adenocarcinoma in situ in 0.5%. The cure rates from loop electrosurgical excision for all grades of dysplasia average 96%.

A histologic diagnosis of CIN should be made before proceeding with loop electrosurgical excision. If loop excision is used instead of colposcopic biopsy (the see-and-treat philosophy), negative specimens will be found in 20-40%–an unacceptably high rate. Furthermore, patients with biopsy-proven low-grade lesions may have up to 40% negative loop specimens. Only those patients with highgrade cytology and obvious colposcopic lesions who may not return for treatment may be considered for the see-and-treat technique. This approach has been used in the United Kingdom, where waiting lists for treatment of abnormal cytology are unusually long, and in the United States for health departments or areas where workers move rapidly from one community to the other.

The management of positive margins at the time of electrosurgical excision is controversial. If the margins suggest invasive cancer, a repeat conization with cold cauterization is indicated because the electrosurgical artifact may interfere with the determination of the depth of invasion. If the patient has a CIN lesion at the margin, follow-up with endocervical sampling and colposcopy at 3 months is indicated. If all margins are negative, two additional examinations 3 months apart are sufficient to establish clearance of the lesion. If the follow-up evaluation result is positive, repeat conization is indicated. A series of loop excisions were reported in which 44% of women had incomplete excision of CIN. Despite this, 95% of the patients remained free of recurrence during follow-up.

Follow-up of patients treated by any modality should include an endocervical brush cytology specimen and col-poscopy at 3-4 months posttreatment. After a negative first evaluation, patients may be followed with cytologic assessment at 6-month intervals.
The histologic diagnosis and the extent of the lesion always must be determined before treatment is performed. A variety of techniques have been used to treat CIN, including surgical excision, cryosurgery, laser vaporization, and loop electrosurgical excision. All of these modalities have a small (2-4%) risk of hemorrhage, later cervical stenosis, and infertility. Cytologic follow-up at approximately 3-month intervals after I year is appropriate.

Ablative therapy such as cryosurgery or laser vaporization is appropriate when the following conditions exist:
• There is no evidence of microinvasive or invasive cancer on cytology, colposcopy, endocervical sampling, or biopsy;
• The lesion is located on the ectocervix and can be seen entirely; and
• There is no involvement of the endocervix as determined by colposcopy and endocervical sampling.
Cryosurgery should be used only for small, low-grade lesions that can be easily covered by the cryoprobe. Several large series indicate a 93-96% cure rate for CIN I and II, but a 77-92% cure rate for CIN III.

Laser vaporization may be chosen for patients who have either large lesions on the exocervix that extend onto the vagina or an irregular “fishmouth” cervix with deep clefts. The major advantage of laser vaporization therapy is the ability to control the depth and width of destruction by direct vision through the colposcope. Destruction of the cervical tissue to a depth of 3.8 mm will ablate all of the involved glands in 99.7% of cases. The standard procedure for laser vaporization is to destroy the tissue to a depth of 7 mm, where 100% of the endocervical glands will have been destroyed. The success rates for laser vaporization range from 83% to 97% for CIN I and II and from 77% to 96% for CIN III. More recent series indicate a greater than 90% cure rate in patients with CIN III. Excisional therapy by conization, laser excision, or loop electrosurgical excision is indicated when the operator determines there is a need for a tissue specimen to rule out invasion, when there is an abnormal finding on endocervical curettage, or when colposcopy is unsatisfactory.

Analysis of the screening programs in British Columbia indicate that low-grade lesions in women younger than 34 years of age will regress spontaneously 84% of the time. For women older than 34 years, 40% of lesions will regress. Despite the fact that most low-grade lesions will regress spontaneously, some physicians are unwilling to manage these lesions expectantly. However, it is acceptable to repeat the Pap test in 4-6 months; if the result is abnormal, colposcopy may be performed at that time. When a woman has a colposcopically abnormal transformation zone and a low-grade squamous intraepithelial lesion is documented by biopsy, destruction of that abnormal transformation zone is acceptable. However, no treatment and monitoring by cytologic and colposcopic examination every 4-6 months are reasonable options. If a lesion persists for more than 1 year, treatment should be recommended at that time because of the diminished likelihood of spontaneous regression.

Any woman with a cytologic specimen suggesting the presence of a high-grade lesion should undergo colposcopy and directed biopsy. No other management approach is currently acceptable. After confirmation of a high-grade lesion, therapy aimed at destruction or removal of the entire transformation zone should be performed. The modality of treatment is based on the location and size of the lesion, the skill of the operator, and the need for further diagnostic materials.
If a high-grade squamous lesion is reported during pregnancy, the patient should undergo colposcopy and repeat cytology. If the lesion is completely seen and there is no suggestion of invasive carcinoma on the colposcopic or cytologic evaluation, treatment can be delayed until after delivery of the fetus. Vaginal delivery can be anticipated. If the patient presents for colposcopy in the first or second trimester and a lesion is visible, a directed cervical biopsy to confirm the absence of invasion is indicated. Biopsy may be delayed until after delivery in patients in the third trimester with no evidence of invasion on colposcopy or cytology.

A report of atypical glandular cells of undetermined significance should indicate, when possible, whether an endometrial or endocervical origin is favored. Atypical endometrial cells should be evaluated by endometrial biopsy. Atypical endocervical cells are further subclassified as favoring either a reactive or a neoplastic process. In a series of 63 patients, 2 women had invasive adenocarcinoma, 5 women had adenocarcinoma in situ, and 17 women had high-grade squamous intraepithelial lesions. Women with atypical glandular cells of undetermined significance should undergo colposcopy with directed biopsy and evaluation of the endocervical canal by endocervical curettage or brush. If the abnormality is not resolved, further diagnostic tests such as conization or hysteroscopy should be considered. Endometrial biopsy should be considered in women older than age 35 with this report. Consultation with a gynecologic oncologist may be helpful if all the results of the diagnostic tests are negative.

There are several management options for patients whose tests are classified as ASCUS. Some reports have indicated that there is a 10-40% rate of CIN found in patients with this report. Invasive cancer is very rare.
The 1991 Bethesda Conference recommended classifying ASCUS as “favor reactive” or “favor neoplasia.” The validity of this subclassification in predicting CIN by biopsy was subsequently confirmed. For those patients whose ASCUS test results favor a reactive process, the appropriate management is to repeat the Pap test in 4-6 months. If subsequent test results are abnormal, the patient should be scheduled for colposcopy. If there are three consecutive negative results within 2 years, the patient can be returned to routine screening.
A report of ASCUS in postmenopausal women not taking hormone replacement therapy may be due to atrophy, and a course of topical estrogen therapy may result in a normal report. If the Pap test is still equivocal after estrogen therapy, colposcopy should be considered. Colposcopy should be considered as initial evaluation for patients with ASCUS test results who previously have been treated for CIN, have a history of poor compliance to follow-up, or whose ASCUS Pap test result is qualified by a statement indicating that a neoplastic process is favored.

Ideally the patient with an ASCUS test result would have an intermediate triage test that is less expensive than colposcopy and more reliable than repeat cytology to direct her further care. Human papillomavirus testing has been evaluated in several studies and shows a sensitivity for the detection of high-grade lesions between 74% and 93 %.

Glandular Cell Abnormalities
Endometrial Cells. The presence of endometrial cells, cytologically benign, in a postmenopausal woman not receiving exogenous hormones should be investigated even when the cells are normal in appearance. Such cells may be associated with inadvertent sampling of the lower uterine segment, endometrial polyps, endometrial hyperplasia, or carcinoma. If the patient is taking hormone therapy, endometrial cells can be normal. (Endometrial cells on a Pap test from a pre-menopausal woman are considered a normal finding regardless of the phase of the menstrual cycle.)
Atypical Glandular Cells of Undetermined Significance. The term “atypical glandular cells of undetermined significance” is used to report changes beyond those encountered in the benign reactive processes but insufficient for a diagnosis of adenocarcinoma. The report should indicate whether the cells are thought to be of endocervical or endometrial origin, when possible.
Adenocarcinoma. A report of adenocarcinoma indicates a probable invasive tumor. The report should specify whether an endometrial, endocervical, or extrauterine site is suspected.
Other Neoplasias. Other malignant neoplasms may be suspected on the basis of certain cytologic findings. These include small cell carcinoma, melanoma, lymphoma, and sarcoma. When originally published, the Bethesda System included a directive for the cytopathologist to make a recommendation for further patient evaluation when appropriate. This recommendation was deleted in the second Bethesda workshop. The cytology report should not attempt to direct therapeutic management of the patient, but may include suggestions for additional cytologic or tissue evaluation if the cytopathologist believes that additional material will assist in clarifying the diagnosis. When atypical squamous cells are associated with atrophy, the cytopathologist may suggest estrogen therapy to help resolve the diagnostic uncertainty.
