Diagnosis, Therapy and Follow-up of Cervical Cancer. Guideline of the DGGG, DKG and DKH (S3-Level, AWMF Registry No. 032/033OL, May 2021) – Part 2 with Recommendations on Psycho-oncology, Rehabilitation, Follow-up, Recurrence, Palliative Therapy and Healthcare Facilities

Abstract

Aim This is an update of the interdisciplinary S3-guideline on the Diagnosis, Therapy and Follow-up of Cervical Cancer (AWMF Registry No. 032/033OL), published in March 2021. The work on the updated guideline was funded by German Cancer Aid (Deutsche Krebshilfe) as part of the German Guideline Program in Oncology. The guideline was coordinated by the German Society of Gynecology and Obstetrics (Deutsche Gesellschaft für Gynäkologie und Geburtshilfe, DGGG) and the Working Group on Gynecological Oncology (Arbeitsgemeinschaft Gynäkologische Onkologie, AGO) of the German Cancer Society (Deutsche Krebsgesellschaft, DKG).

Method The process used to update the 2014 S3-guideline was based on an appraisal of the available evidence using the criteria of evidence-based medicine, adaptations of existing evidence-based national and international guidelines or – if evidence was lacking – on the consensus of the specialists involved in compiling the update. After an initial review of the current literature was carried out according to a prescribed algorithm, several areas were identified which, in contrast to the predecessor version from September 2014, required new recommendations or statements which would take account of more recently published literature and the recent appraisal of new evidence.

Recommendations The short version of this guideline consists of recommendations and statements on palliative therapy and follow-up of patients with cervical cancer. The most important aspects included in this updated guideline are the new FIGO classification published in 2018, the radical open surgery approach used to treat cervical cancer up to FIGO stage IB1, and the use of the sentinel lymph node technique for tumors ≤ 2 cm. Other changes include the use of PET-CT, new options in radiotherapy (e.g., intensity-modulated radiotherapy, image-guided adaptive brachytherapy), and drug therapies to treat recurrence or metastasis.

II  Guideline Application

Purpose and objectives

The rationale for this guideline was the problems relating to security of care as well as the fact that mortality and morbidity rates have not decreased much in the last 15 years and the current therapies administered to patients with cervical cancer vary greatly. The aim of this updated guideline remains the same as that of the previous version from 2014. This guideline “Diagnosis, Therapy and Follow-up of Cervical Cancer” is an evidence- and consensus-based instrument for the care of patients with cervical cancer. It provides patients with scientific, up-to-date, economically viable procedures for diagnosis, therapy, follow-up and rehabilitation which are appropriate for the various stages of disease. The current version of the guideline aims to provide a basis for clinical decision-making on appropriate treatment. The guideline also incorporates the concept of shared decision-making.

Targeted areas of patient care

The area covered by the guideline ranges from diagnosis to therapy and the follow-up of patients with cervical cancer and includes patients with microinvasive lesions/high-grade precursor lesions (but excludes patients with early precursor lesions/preinvasive lesions). The scope of the guideline is intersectoral. It covers outpatient and in-patient care as well as rehabilitation.

Target user groups

This S3-guideline is aimed at all patients with cervical cancer (including microinvasive lesions/high-grade precursor lesions but excluding early precursor lesions/preinvasive lesions) and their families.

Intended audience

The recommendations of the guideline are for all physicians and professional groups involved in the outpatient and/or in-patient care and rehabilitation of patients with cervical cancer.

The guideline is also intended for

• medical and scientific specialist societies and professional associations,

• special interest groups for women (womenʼs health organizations, patient organizations, and self-help organizations),

• quality assurance institutions and federal and state-level projects (e.g., AQUA, ADT, IQWiG, GEKID, gesundheitsziele.de, IQTIG),

• health policy institutions and decision-making bodies at federal and state levels,

• certification institutions (e.g., DKG),

• funding bodies.

Adoption and period of validity

The validity of this guideline was confirmed by the executive boards/heads of the participating medical professional societies, working groups, organizations and associations as well as by the boards of the DGGG, SGGG and OEGGG and the DGGG/OEGGG/SGGG guidelines commission and was thus approved in its entirety. This guideline is valid until October 2025. Because of the contents of this guideline, this period of validity is only an estimate. If changes are urgently required, then the guideline can be updated earlier; if the information in the guideline still represents the current state of knowledge, then the guidelineʼs period of validity can be extended.

III  Methodology

Basic principles

The method used to prepare this guideline was determined by the class to which this guideline was assigned. The AWMF Guidance Manual (version 1.0) has set out the respective rules and requirements for different classes of guidelines. Guidelines are differentiated into lowest (S1), intermediate (S2), and highest (S3) class. The lowest class is defined as consisting of a set of recommendations for action compiled by a non-representative group of experts. In 2004, the S2 class was divided into two subclasses: a systematic evidence-based subclass (S2e) and a structural consensus-based subclass (S2k). The highest S3 class combines both approaches. This guideline has been classified as: S3.

The methodological approach used to compile this guideline is described in the guideline report which is freely available on the homepage of the German Guideline Program in Oncology (https://www.leitlinienprogramm-onkologie.de/leitlinien/zervixkarzinom/) and the homepage of the AWMF (http://www.awmf.org/).

Grading of evidence based on SIGN

To classify the risk of bias in identified studies, this guideline used the system of the Scottish Intercollegiate Guidelines Network (SIGN) described in [Table 5] (cf. https://www.sign.ac.uk/media/1050/sign50_2019.pdf).

Tab. 5 Classification of levels of evidence according to SIGN.

Level	Description
1++	High-quality meta-analyses, systematic review of RCTs, or RCTs with a very low risk of bias.
1+	Well-conducted meta-analyses, systematic reviews, or RCTs with a low risk of bias.
1−	Meta-analyses, systematic reviews, or RCTs with a high risk of bias.
2++	High-quality systematic reviews of case-control or cohort studies, or High-quality case-control or cohort studies with a very low risk of confounding, bias or “chance” and a high probability that the relationship is causal.
2+	Well-conducted case-control studies or cohort studies with a low risk of confounding, bias or “chance” and a moderate probability that the relationship is causal.
2−	Case-control studies or cohort studies with a high risk of confounding, bias or “chance” and a significant risk that the relationship is not causal.
3	Non-analytical studies, e.g., case reports, case series.
4	Expert opinion

Grading of recommendations

This guideline indicates the level of evidence (based on the SIGN classification) of underlying studies and, if recommendations are made, the strength of the recommendation (grade of recommendation) for all evidence-based statements and recommendations. As regards the strength of the recommendation, the guideline differentiates between three levels of recommendation ([Table 6]), with the level reflected in the wording used in the respective recommendation, as shown below.

Tab. 6 Grade of recommendation.

Symbol	Description of level of obligation to comply with the recommendation	Terminology
A	Strong recommendation, highly binding	must/must not
B	Recommendation, moderately binding	should/should not
0	Open recommendation, not binding	may/may not

In principle, the grade of recommendation is based on the strength of the available evidence. For example, if there is a high level of evidence (e.g., provided by high-quality meta-analyses/systematic reviews of RCTs or several methodologically high-quality RCTs), then a strong recommendation is given (grade of recommendation: A, “must”).

But the following criteria are also taken into account and can result in the level of recommendation being upgraded or downgraded:

Consistency of study results

• Example: The effect estimates for study results diverge, showing no consistent tendency.

Clinical relevance of endpoints and effect sizes

• Example: Even though there are a number of studies with results which point in a specific direction, the importance of the selected endpoints and/or effect sizes are not considered relevant.

Benefit-to-risk ratio

• Example: Although the intervention has a proven benefit, it is also associated with a relevant harm which mitigates against giving an unqualified recommendation.

Ethical obligations

• Example: Downgrading: For ethical reasons, an intervention with a proven benefit cannot be unreservedly offered to patients. Upgrading: Strong recommendation based on case-control studies, because an RCT cannot be carried out for ethical reasons.

Patient preferences

• Example: An intervention with a proven benefit is not strongly recommended as it is rejected by patients who consider it to be onerous or not feasible.

Applicability, practicability of care

• Example: An intervention with proven positive effects cannot be recommended because structural reasons mean that it is not available in regional healthcare systems.

Statements

Statements are expositions or explanations of specific facts, circumstances or problems which do not directly call for action. They are adopted following a formal consensus procedure using the same approach used for recommendations, and they may be based either on study results or on expert opinions.

Achieving consensus and strength of consensus

At structured NIH-type (S2k/S3 level) consensus conferences, authorized participants attending the conference vote on draft statements and recommendations. Conferences are structured as follows: a recommendation is presented; participants can ask questions about the contents of the recommendation; amendments can be proposed; all proposed amendments are voted on. If a consensus (> 75% of votes) cannot be reached, there is another round of discussions, followed by another vote. At the end of the session, the strength of the consensus is determined based on the number of persons who participated in the session ([Table 7]).

Tab. 7 Strength of consensus based on the extent of consensus.

Symbols	Level of consensus	Extent of agreement in percent
+++	Strong consensus	> 95% of participants agree
++	Consensus	> 75 – 95% of participants agree
+	Majority agreement	> 50 – 75% of participants agree
–	No consensus	< 51% of participants agree

Expert consensus

When the guideline authors decide to make statements/recommendations based on the expert consensus of the guideline authors, such statements/recommendations are identified by the phrase “expert consensus” (EC). No symbols are used to grade such recommendations; the strength of the expert consensus is indicated by the wording used (must/should/may) in accordance with the grading shown in [Table 6].

IV  Guideline

1  Supportive therapy

Supportive therapy is an integral part of the treatment concept. There may be side effects in the form of acute changes which occur during or immediately following treatment or appear as late sequelae. There is a DACH S3-guideline “Supportive Therapy for Oncological Patients” (long version 1.3 – February 2020, AWMF registry no. 032/054OL) on the supportive care for cancer patients [1].

2  Psycho-oncology and Quality of Life

2.1  Psycho-oncological support

2.2  Measuring quality of life

3  Integrative Medicine

3.1  Counselling about complementary and alternative medicine (CAM)

3.2  Importance of alternative medicine

4  Rehabilitation

4.1  Physiotherapy treatment during rehabilitation

4.2  Treatment of lymphedema during rehabilitation

4.3  Treatment of fatigue syndrome during rehabilitation

5  Follow-up

Follow-up of patients with cervical cancer starts when surgical and/or radiochemotherapy has been completed. Follow-up includes taking the patientʼs medical history, a physical examination, and a medical consultation and support. If suspicious findings are detected at follow-up or if there is a clinical suspicion of disease, diagnostic imaging should be carried out based on the symptoms to detect locoregional or distant recurrence [12] – [18].

5.1  Follow-up without suspicion of recurrence

5.2  Tumor markers

5.3  Expanded diagnostic workup for suspicion of recurrence

5.4  HPV vaccination after conization

6  Local Recurrence

The rate of recurrence for cervical cancer for all tumor stages and forms of therapy is between 22 and 31% [19], [20]. Known risk factors for local/locoregional recurrence are the FIGO stage (tumor diameter, parametrial tumor invasion, metastatic involvement of pelvic lymph nodes), younger age (< 45 years), the histological subtype, and lymphatic invasion L1 [20] – [24].

6.1  Diagnosing local recurrence

6.2  Treatment of local recurrence

6.2.1  Treatment of central tumor recurrence after first-line surgical treatment

6.2.2  Treatment of pelvic wall recurrence after first-line or adjuvant radio-/radiochemotherapy

6.2.3  Palliative treatment of local recurrence (when margin-negative surgery is not possible)

7  Distant Metastasis

7.1  Therapy options for distant metastasis

7.1.1  Isolated metastasis

7.1.2  Disseminated metastases

7.1.3  Systemic therapies in the metastatic setting

7.1.3.1  Targeted therapy

7.1.3.2  Second-line therapies for cervical cancer

8  Palliative Medical Support

Detailed information can be found in the S3-guideline “Palliative Medicine for Patients with Incurable Cancer” (AWMF registry no. 128/001OL) [32]. The statements below were taken from the above-mentioned guideline.

9  The Wish to Have Children

The recommendations in this chapter are based on expert opinions as well as the current S2k guideline on preserving the fertility of patients with oncological disease (AWMF registry number: 015/082; version 1.0; September 2017), as the data are not sufficient for an evidence-based recommendation [41]. For more information on fertility preservation methods and their success rates, please refer to the S2k guideline mentioned here.

10  Cervical Cancer in Pregnancy

The published incidence of cervical cancer in pregnancy is low and lies between 0.02 and 0.9% [42].

11  Incidental Cervical Cancer After Simple Hysterectomy

12  Neuroendocrine Cervical Carcinoma

Neuroendocrine cervical carcinoma (NECC) is a particularly rare but very high-risk form of cervical cancer with an incidence of around 1 – 1.5% of all cervical cancers. Overall, NECC has a poor prognosis, irrespective of the therapy administered, and has a poorer prognosis than adenocarcinoma or squamous cell carcinoma [44] – [49]. Already in the early stages of disease (I to IIA), 40 – 60% of patients develop regional lymph node metastasis or hematogenous distant metastasis. The 5-year survival rate is between 34 – 37%, with a mean overall survival of 40 months [50], [51]. The most common therapy used to treat early-stage disease (FIGO I–IIA) is radical hysterectomy, optionally followed by adjuvant chemotherapy (or a first-line neoadjuvant concept), and this appears to have the best survival rates [50], [51]. Because of its histological similarity to small cell bronchial carcinoma (SCLC), treatment often consists of chemotherapy with etoposide and cisplatin/carboplatin (PE) or vincristine, adriamycin and cyclophosphamide (VAC) [50], [51]. Treatment of locally advanced NECC (IIB–IVB) or recurrence consists of combined radiochemotherapy or chemotherapy [50], [51]. To facilitate therapy planning, cases may be presented to specialist tumor boards for neuroendocrine tumors.

13  Healthcare Facilities

13.1  Treatment in oncological centers

After the gynecological examination has been carried out, the patient will need to undergo further histological investigation if results of the cytological pap smear and/or HPV test are abnormal, with further examinations carried out either at a local center with the appropriate expertise or in a certified gynecological dysplasia clinic/unit ([Fig. 1]).
