Abstract
Purpose On January 1st, 2018, the ÖGZ (Austrian Society of Cytology) revised its cytological nomenclature to make it more similar to the 2015 Bethesda system. Following these changes, the Austrian Society of Gynecology and Obstetrics felt it necessary to revise the approach currently used in Austria to diagnose and treat CIN and to review the procedures to be followed when the quality of cytological specimens is unsatisfactory. It was not possible to adopt the German S3 guideline “Prevention of Cervical Cancer” in its entirety, because the Munich III gynecological cytology nomenclature used in Germany is not used in Austria. This made it necessary to compile a separate scientific opinion for Austria.
Methodology The OEGGG worked together with the ÖGZ (Austrian Society for Cytology), AGO Austria (Austrian Working Group for Gynecological Oncology), the AGK (Colposcopy Working Group), and physicians representing gynecologists in private practice. The different scientific associations nominated representatives, who attended the various meetings. After an in-depth analysis of the recent literature, three meetings and numerous votes by telephone, we were able to achieve a consensus about the contents of this guideline.
Recommendations The guideline provides recommendations for the diagnosis and treatment of CIN which take account of the gynecological cytology nomenclature used in Austria.
Key words: cervical intraepithelial neoplasia, cytology, colposcopy
1 Introduction
This guideline describes the approach currently recommended in Austria for the work-up of abnormal cytological findings and positive HPV test results, the recommended treatment for squamous (SIL, CIN) and glandular (AIS) cervical intraepithelial neoplasia and the procedures to be followed when cytological specimens are unsatisfactory.
Abnormal findings can occur during primary cytological screening and in the context of primary HPV-based screening for cervical cancer with cytological triage. Within the currently existing opportunistic screening program for cervical cancer we recommend that women aged 30 years and above undergo validated testing for HPV at least every 3 years. This recommendation applies both to HPV-vaccinated and non-HPV-vaccinated women. Routine co-testing should be avoided; the procedures can be carried out alternately ( 19 , 24 ; cf. also 3.4).
This guideline aims to harmonize and standardize management and avoid under- and over-treatment. A work-up based on the recommendations of this guideline will reduce the number of conizations and prevent delays in diagnosis. Women with cytological abnormalities and with persistent oncogenic HPV infections require a careful diagnostic work-up and a colposcopy examination. While there are several options for borderline and low-grade lesions, high-grade cytological lesions should be investigated immediately. Simply repeating the cytological smear without a colposcopy and without ascertaining the patientʼs HPV status (for patients aged > 30 years) is not recommended. According to the Austrian Vaccination Schedule, HPV vaccination is recommended for all women up to the age of 45 years. Primary testing for HPV is preferred in HPV-vaccinated women aged 30 years and above 10 . Any deviations from the recommendations given in this guideline must be justified and recorded for forensic purposes.
The histological terminology used in this guideline corresponds to the current histological WHO 2014 classification 13 and its German-language version 23 . When examining women who wish to have children, it is important that the pathologist reporting the findings differentiates HSIL (CIN II) from HSIL (CIN III) as careful differentiation will allow the treating physician to wait and see whether any regression of the CIN II occurs which could help to avoid obstetric complications subsequent to conization 26 .
The colposcopic terminology corresponds to the Rio de Janeiro 2011 nomenclature of the International Federation of Cervical Pathology and Colposcopy (IFCPC) 4 and its approved German-language version 6 , 20 .
Cytological findings are recorded in accordance with the guidelines of the Austrian Society for Cytology (ÖGZ) on the nomenclature and reporting of cervical cytology findings 21 .
2 Methodology
Statements and recommendations were voted on at three consensus conferences 3 , 17 . The statements and recommendations were discussed at the consensus conferences, which were held in Vienna on 30 January 2018, 14 March 2018 and 20 June 2018, and participants agreed to proposals during the final moderated session. The compilation of this scientific opinion also took the previous recommendations (compiled in 2015) and the recommendations of the German S3 Guideline on the Prevention of Cervical Cancer 24 into special consideration.
During the consensus process, participants who were present voted on the wording of the scientific opinion during the sessions, while participants who had been excused from attending voted by telephone. As no systematic search, selection, evaluation and synthesis of evidence was carried out, no level of evidence is provided for the recommendations and statements.
3 Diagnosis
The following examination procedure is recommended to determine whether any dysplastic changes of the cervix uteri are present.
3.1 Inspection and colposcopy
Unaided visual inspection after cleaning of the cervix uteri; targeted cytological smear (great care must be taken to ensure that a smear is obtained from the transformation zone!); a smear specimen may be taken to test for HPV; acetic acid test (3 – 5% acetic acid); Schillerʼs iodine test may be used. Findings must be recorded (in writing, using a drawing, possibly even photographed or videoed).
3.2 Conventional cytology
Smear samples should be obtained from the ectocervix and endocervix (transformation zone) using suitable sampling tools (spatula and/or brush). The sample must be spread thinly and evenly, usually on a slide, and immediately fixed using a suitable spray, or the sample can be placed in 96% alcohol for at least 10 minutes. Alternatively, thin-layer cytology can be used to obtain a sample.
3.3 Histological specimens
Tissue sampling can be done either by:
punch biopsy with samples taken from the area of maximum changes using biopsy forceps during colposcopy performed to visualize the area (take several biopsies if necessary) 28 .
endocervical curettage (if there is a suspicion of endocervical involvement); pregnant patients should not undergo endocervical curettage.
3.4 Testing for HPV
Persistent infection with high-risk human papillomavirus (high-risk HPV) is a prerequisite for developing cervical cancer or its precursors 5 , 27 . The only exceptions are a few rare cervical adenocarcinoma subtypes 8 . A latency period of several years is assumed to exist between initial HPV infection and the development of invasive carcinoma. This means that a negative high-risk HPV test has a high negative predictive value; the existence of cervical dysplasia requiring treatment over the longer term can be largely excluded. Subtype-specific HPV tests (for HPV type 16 and type 18) provide additional predictive and prognostic information. Testing for low-risk HPV subtypes (low-risk HPV) provides no additional relevant Information and should therefore not be carried out.
3.4.1 Methods for diagnosing high-risk HPV
Many different tests to detect high-risk HPV are used all over the world. As the HPV tests used in Europe are currently not subjected to standard quality controls, it is important to only use tests in routine clinical practice which comply with the internationally accepted criteria of Meijer and Stoler 1 , 15 , 25 . The following tests currently fulfil these quality criteria: Digene Hybrid Capture 2 High-Risk HPV DNA Test ® (QIAGEN); Cobas HPV Test ® (Roche); Cervista ® HPV HR (Hologic); APTIMA HPV Assay ® (Hologic) Papillocheck ® (Greiner Bio One); Abbott RT High-risk HPV Test ® (Abbott); BD Onclarity HPV Test ® (BD) 24 .
4 Management of Abnormal Cytological Findings and Positive HPV Test
4.1 Management following positive HPV test ( Fig. 1 )
Fig. 1.

Management following positive HPV test. [rerif]
Colposcopy and cytological follow-up examinations should be carried out within 6 months at the latest 24 .
4.2 Management of patients with PAP III (ASCUS, ASC-H) ( Fig. 2 )
Fig. 2.

Management of patients with PAP III (ASCUS, ASC-H). [rerif]
HPV testing is recommended in Austria as the primary work-up for PAP III. Patients proven to have high-risk HPV infection should have a colposcopy and histological evaluation without delay.
Patients with PAP III but no evidence of high-risk HPV infection should undergo further evaluation for other possible causes.
Women with Pap III and existing inflammation and/or atrophy can be given a short course of estrogen and/or treated for vaginitis before repeating the cytology test and the histological evaluation.
4.3 Management of patients with PAP IIID (LSIL) ( Fig. 3 )
Fig. 3.

Management of patients with PAP IIID (LSIL). [rerif]
The detection of high-risk HPV has a higher sensitivity for HSIL+ (CIN III+) than repeat cytology 24 .
4.4 Management of patients with PAP IIIG (AGC-NOS, AGC) ( Fig. 4 )
Fig. 4.

Management of patients with PAP IIIG (AGC-NOS, AGC). [rerif]
If histological findings of women with PAP IIIG and positive for high-risk HPV are negative, they should be referred for diagnostic conization as soon as possible.
4.5 Management of patients with PAP IV (HSIL, AIS) ( Fig. 5 )

Fig. 7.

Procedure after histological verification of LSIL (CIN I), HSIL (CIN II, CIN III), AIS. [rerif]
In accordance with internationally accepted quality standards, a colposcopy should be done prior to carrying out conization or destruction of superficial tissue 16 .
5.1 Resection
Indications:
Persistent CIN I (LSIL) for more than 2 years
Persistent high-risk HPV infection for more than 2 years with additional indications (divergent findings) 12
HSIL (CIN II, III)
Recurrent pathological cytology without a histological correlate
Suspicion of early invasion
Suspicion of AIS
Note: Contrary to the approach used in the USA, in Austria as in other European countries, CIN II are not classified as HSILs which require immediate treatment 24 .
Technique:
Conization using high-frequency loop (loop conization, LEEP, loop excision, loop cone biopsy; LLETZ) is recommended. Because of potential obstetric complications 14 the aim must be to achieve resection with narrow tumor-free margins. Once the patient no longer wishes to have children, the radical excision can be expanded and a larger cone can be resected.
5.2 Superficial destruction
Possible indications:
LSIL (condylomas, CIN I)
Requirements:
Ectocervical location of lesion
Transformation zone can be visualized in its entirety
Previous biopsy
Colposcopy and cytology must be carried out after 6 months to monitor the site.
Currently, opinions differ internationally with regard to evaluating the evidence for superficial destruction.
5.3 Additional procedures after conization
There is some evidence in the literature that HPV vaccination after conization reduces the risk of recurrence 9 , 11 . Indicators of therapy failure include persistent HPV, positive resection margins, older patient age, large lesions, small excision specimen and limited experience of the surgeon 2 .
Prospective observational studies have shown that detection of high-risk HPV is the most sensitive method indicating residual or recurrent lesions 2 . Testing for high-risk HPV should be carried out 6 months after treatment at the earliest.
Resection of HSIL (CIN II, III) with tumor-free margins
Gynecological examinations (colposcopy, cytology) should be carried out at regular intervals to monitor changes.
Testing for high-risk HPV should be carried out 6 months after treatment. If the test results are positive but the results of cytology, histology and colposcopy are unremarkable, a repeat test for high-risk HPV should be carried out after a further 6 months. Women with a negative high-risk HPV test results can be followed up with routine screening performed at regular intervals 7 , 24 .
Resection of HSIL (CIN II, CIN III) without tumor-free margins
Resection of an HSIL without tumor-free margins does not require immediate reconizaton/hysterectomy 22 , 24 . Follow-up colposcopy, cytology and histology examinations should be carried out after 3 – 6 months, although testing for HPV should only be carried out after 6 months. Reconizaton/hysterectomy should only be carried out for persistent HSIL.
Resection of AIS without tumor-free margins
It should be noted that if an AIS is resected without achieving tumor-free margins, a second resection (or a hysterectomy, if indicated) must be carried out in all cases 24 .
6 CIN (SIL) in Pregnancy ( Fig. 8 )
Fig. 8.

CIN (SIL) in Pregnancy. [rerif]
6.1 Diagnosis
Colposcopy
Cytology
Histological evaluation if there is a suspicion of invasion
A biopsy can be carried out safely during pregnancy and should be performed if colposcopy results are unclear and there is a suspicion of invasion. Endocervical curettage is contra-indicated in pregnancy.
6.2 Treatment
Surgical treatment in pregnancy should be reserved for exceptional cases; it should only be done if there is a very high suspicion of invasion and it should only be carried out in specialized centers.
7 Nomenclature and Reporting of Cytological Findings
The contents of this chapter represent a summary of the quality standards/recommendations for gynecological cervical cytology of the ÖGZ (ÖGPath, 2nd revised version of July 2017).
7.1 Additional information provided on the cytological request form
The additional information provided must include:
patient data (name, maiden name, first name, date of birth, insurance number, name of the patientʼs medical insurance company),
date of cytology examination,
name of sender (and of the treating physician, if not identical with sender),
data about the specimen (type of specimen, site where sampled, device used for sampling),
clinical questions and important clinical data such as information about any history of bleeding, information about the patientʼs hormonal status (for example, hormone substitution, ovulation inhibitors, pregnancy, lactation, menopause), colposcopy findings (e.g., inflammation, polyps), abnormal gynecological bleeding, any intrauterine pessaries, previous gynecological or other relevant operations (e.g., conization, hysterectomy), relevant treatment (irradiation, chemotherapy, cytostatic drugs), HPV status, previous pathological cervical cytology findings.
7.2 Assessment of smear adequacy
Assessed smears should be classified into one of the following three groups. The criteria for unsatisfactory smear quality are defined as follows, based on the corresponding criteria of the Bethesda system:
A) Quality of smear: “Can be assessed without difficulty and is representative”
B) Quality of smear: “Unsatisfactory because …”
C) Quality of smear: “Cannot be assessed” (= Pap 0)
Not processed due to technical and/or administrative deficiencies
Processed but could not be evaluated because …
A) Quality of smear: “Can be assessed without difficulty and is representative” (all of the listed criteria must be met):
Pap smear labeled appropriately for identification purposes
Sufficient clinical information is provided
-
Criteria for representativity, method and technical processing:
Adequate number of cells: conventional smear should include between 8000 and 12 000 cells, thin-layer specimen should include a minimum of 5000 well preserved and clearly visible squamous epithelial cells (for instructions and test images to estimate the number of cells present, cf. The Bethesda System, 3rd edition, page 3 et seq. for thin-layer smears and page 11 et seq. for conventional smears, or https://bethesda.soc.wisc.edu/ ) 18 . Determining cell contents using the coated surface of the slide is no longer considered adequate.
Columnar epithelial cells and/or metaplastic cells in patients with ectocervix. Minimum number: at least 10 well preserved endocervical cells and/or metaplastic squamous epithelial cells, present either as individual cells or in groups.
Note: The Bethesda System no longer assumes that insufficient numbers of endocervical cells and/or metaplastic squamous epithelial cells from the transformation zone (EC/TZ) make the specimen unrepresentative; however, the Bethesda classification recommends that the report on the findings must include the information that EC/TZ are lacking.
B) Quality of smear: “Unsatisfactory because …” (one of the following criteria must be met):
-
… not representative
smear specimen lacks sufficient number of cells (estimated number for conventional smear: 5000 to 8000 well preserved and clearly visible squamous epithelial cells ; estimated number for thin-layer specimens: 2000 to 5000). The number of cells can vary depending on the initial clinical situation (pregnancy, hormone therapy, age, etc.).
no or too few columnar epithelial cells and/or metaplastic cells present in specimen (irrespective of the womanʼs age!) from patientʼs ectocervix (see above for reasons).
-
… only limited assessment possible (method and technical processing, etc.):
important clinical information is lacking, cf. II/1
poor fixation
there is slight to moderate cell damage in the form of smear artifacts (crush artifacts)
more than 50 – 75% of epithelial cell components are obscured by blood, inflammatory cells, thick layer of cells, contamination ( Fig. 9 ).
Fig. 9.

PAP II (NILM) but quality of smear is unsatisfactory. [rerif]
C) Quality of smear: “Cannot be assessed” (Pap 0) (one of the following criteria is present)
-
Smear slide cannot be identified or slide cannot be assigned to specific procedure.
Specimen slide is broken or not present (was not received)
-
Criteria for representativity, method and technical processing:
Insufficient number of squamous epithelial cells (less than estimated 5000 squamous epithelial cells in conventional smear or less than 2000 squamous epithelial cells in thin-layer specimens)
Very poor or no fixation; air-drying artifacts
More than 75% of epithelial cells obscured by blood, inflammation, thick layer of cells, contamination
Extensive cell damage due to smear artifacts (crush artifacts)
Note: Data on representativity must be reported for all cases, particularly for PAP I and II. PAP I requires a smear which is representative and can be clearly evaluated. Although it is of secondary importance, reports on cases with PAP III or higher should also include information on the quality of the smear, including whether the smear is representative/can be clearly assessed. The data must be recorded even if the suspicious findings (PAP III or higher) are not representative or insufficiently representative as any such findings must be investigated further without delay.
7.3 Nomenclature of findings
Cytological findings must be reported using a mandatory nomenclature und national ( Table 1 ) and international classification. The results, classified according to the Bethesda System, should be included in the report on findings.
Table 1 2018 Austrian gynecological cytology nomenclature and Bethesda equivalent.
