Configuration of services

Review question

What is the most effective configuration of services for referral, risk assessment and risk management for women at increased risk of ovarian cancer (including fertility, menopause and psychological support services)?

Introduction

Women with a familial risk of ovarian cancer are asked to manage a complex set of health needs. They need to understand their lifetime risk of ovarian cancer and decide upon interventions that can impact on their fertility, self-image, and menopause status. In addition, surgical interventions are not without their own set of risks. Services need to be established that can holistically support women with a familial risk of ovarian cancer through this process. However, the exact nature and composition and configuration is not fully known.

Herein we discuss the evidence base for these recommendations and outline how these services should be commissioned. Where there is a lack of evidence, we will also outline key research priorities.

Declarations of interest were recorded according to NICE’s conflicts of interest policy.

Effectiveness/ Service delivery evidence

Included studies

Eleven observational studies were included for this review. They compared a variety of service delivery models mainly against a standard service delivery, and mainly in women with ovarian cancer.

Three studies compared a mainstreaming cancer genetic testing/counselling/service with no mainstreaming cancer genetic service in women with ovarian cancer (Ip 2020, Yoon 2022) and in women with breast cancer (Scott 2020).

One study compared a streamlined pre-test genetic education and genetic testing service with a standard service delivery in women with ovarian cancer (Powell 2020).

Two studies compared a gynaecologic oncologist-initiated genetic testing service with a standard genetic testing service (Piedimonte 2020, Rumford 2020).

Three studies compared a model with the addition of an embedded genetic counsellor in the medical and/or gynaecologic oncology clinic with a standard service delivery (Rana 2021, Senter 2017, Warias 2021).

One study compared a reflex BRCA1/2 tumour testing with a no reflex BRCA1/2 tumour testing in women with ovarian cancer (McCuaig 2020).

One study compared a multidisciplinary one-stop follow-up clinic with a no multidisciplinary one-stop follow-up clinic in BRCA1/2 carriers (Pichert 2010).

The included studies are summarised in Table 2.

Summary of the evidence

Studies reported a variety of different configuration services for referral, risk assessment and management, therefore it is difficult to draw an overall conclusion. Effect estimates could not be calculated for all studies as not all of them reported relevant data, therefore some of the results reported here are based on the significance or non-significance of the findings reported in the studies.

Women with ovarian cancer
Mainstream germline genetic testing program versus cancer genetic service

Low quality evidence comparing mainstream genetic testing to the cancer genetic service was inconclusive in terms of time from blood collection to report/return to the treating oncologist. Although it was not reported whether there was a statistical difference between the mainstream genetic testing and the standard genetic service, it was reported that the average time from blood collection to report was 7 days longer with the mainstream genetic testing program than with the cancer genetic service.

Mainstreaming genetic counselling versus standard genetics referral pathway

Very low to moderate quality evidence indicated no important difference in terms of either psychosocial aspects within the cancer genetic counselling setting (a proxy for quality of life) or with the genetic counselling satisfaction among women participating in the mainstreaming genetic counselling as compared to the standard cancer referral pathway.

Streamlined pre-test genetic education and genetic panel testing versus standard counselling and testing

One study did not report whether time from diagnosis to genetic test result or to blood draw was significantly different between a streamlined pre-test genetic education and genetic panel testing service delivery model (where testing is provided by the managing gynaecologic oncologists) and the standard counselling and testing. However, it reported that the time from diagnosis to genetic test result (median 12 days shorter) and also to blood draw (median 7 days shorter) was shorter with the streamlined pre-test genetic education and genetic testing panel testing service as compared to the current counselling and testing.

Very low to low quality evidence showed no important difference in terms of patient satisfaction associated with the genetic testing, including, for example, uncertainty, positive experience, satisfaction with time for discussion and adequacy of information provided and others when compared the streamlined pre-test genetic education and genetic panel testing with the current counselling and testing. In terms of distress associated with genetic testing, there was no evidence of an important difference between the two services (low quality evidence).

Gynaecologic oncologist-initiated genetic testing model versus traditional genetics referral

Very low quality evidence showed a shorter time from diagnosis to genetic testing (median 114 days shorter) and a shorter delay between the testing and the result (median 20.5 days shorter) with the gynaecologic oncologist-initiated genetic testing model as compared to the traditional care model It is not clear whether there was a significant difference between the two models in terms of the above outcomes as it was not reported in the study.

In terms of time between blood sample acquisition and return of the result to the treating oncologist, it is not clear whether there was any significant difference between the two models as it was not reported. However, it was reported that the turnaround time was shorter (mean 127.6 days shorter) with the gynaecologic oncologist-initiated genetic testing model.

Embedded genetic counsellor in the medical and gynaecologic oncology clinic versus standard clinic

Low quality evidence showed a shorter time from initial consultation to genetic counselling or from referral to scheduling in genetics, and to completion of genetics consultation with an embedded genetic counsellor in the medical/gynaecologic oncology clinic or with a cancer genetic counsellor on-site in the gynaecologic oncology clinic as compared to standard care models. In terms of the proportion of patients seen for ovarian cancer treatment who received genetic testing within 3 months of their initial visit (a proxy for the time to treatment outcome), moderate quality evidence showed an important benefit of the service with an embedded genetic counsellor as compared to the standard service.

Genetics embedded model versus no genetic embedded model

One study reported a shorter time from referral to scheduling in genetics (mean 3.13 months) and to completion of genetics consultation (mean 0.85 months) with the genetics embedded model as compared to no genetics embedded model (moderate quality evidence).

Collaborative care model versus no collaborative care model

In terms of time from diagnosis to referral and also to first appointment, one study reported a shorter time with the collaborative care model involving the integration of genetic counsellors into tumour board round as compared to no collaborative care model (low quality evidence).

Reflex BRCA1/2 testing versus no reflex testing

Very low quality evidence from 1 study assessing the reflex BRCA1/2 tumour testing (where genetic testing of tumour tissue is initiated by a pathologist as part of surgical pathology review) reported a shorter time to referral for genetic counselling (median 26 days shorter) with the reflex tumour testing model as compared to the no reflex tumour testing model.

Women with breast cancer
Nurse-led mainstreaming cancer genetics (MCG) service verses pre-MCG service

Very low quality evidence from 1 study assessing a specialist, nurse-led mainstreaming cancer genetics service in women with a positive breast cancer diagnosis having a genetic test was inconclusive as it did not report whether there was a statistical difference between the specialist, nurse-led mainstreaming cancer genetic service and the usual service in terms of time from genetic testing to the test result.

BRCA1/2 carriers
Multidisciplinary one-stop follow-up clinic verses no one-stop clinic

In terms of the recruitment to trials, moderate quality evidence showed an important benefit of the multidisciplinary clinic as compared to no multidisciplinary clinic.

The committee’s discussion and interpretation of the evidence

The outcomes that matter most

Overall survival and quality of life were prioritised as critical outcomes by the committee because they indicate the impact of services on the long-term health and wellbeing of those at increased risk of ovarian cancer. Patient satisfaction was also a critical outcome as a way of comparing the relative acceptability of different service configurations.

Access to services was chosen an important outcome to capture the efficiency and convenience of different service models. Examples of access were local availability, waiting times for services, time to diagnosis or identification of a familial risk, time to treatment (risk reducing), and access to clinical trials.

The quality of the evidence

The quality of the evidence from the included studies was assessed with GRADE and was rated as mainly very low or low mainly due to serious risk of bias of individual studies and in some cases also due to imprecision of the estimate. Serious risk of bias was typically due to incomplete adjustment for confounders, so baseline differences between people seen in different service configurations could bias the results.

There was no evidence identified for overall survival and local availability. This meant that the committee used their experience and expertise to estimate the longer term impact of different service configurations.

Benefits and harms

The committee noted that the variety of configurations of services reported in the evidence made it difficult to identify a single ideal service configuration, but they noted that certain features such as embedded specialisms within the team, mainstreaming of genetic counselling and teams that collaborated were associated with important benefits, that is better outcomes such as shorter waiting times for referral, and subsequently to genetic counselling and testing. The relatively small number of studies and uncertainties about the reported effects and the way the studies were conducted meant the recommendations were largely based on their knowledge and experience.

Commissioners and services providers in all settings

The committee explained that there are well-established referral mechanisms and pathways to clinical genetics. However, there is variation in the referral criteria, the minimum dataset accepted prior to referral, and also among clinicians in primary and secondary care regarding whether and how to make a referral. Therefore, the committee aimed to provide guidance that should help reduce this variation in practice.

They agreed, based on their experience, that commissioners and service providers should ensure that there are referral pathways from primary or secondary care for people at risk of having a pathogenic variant associated with ovarian cancer could be facilitated by clear referral criteria, an online referral form for referral, family history questionnaire filled out by the affected person, and standardised patient information leaflets (for example, a web page or paper form). For example, currently some genetic specialist services do not accept patients without a detailed family history, including a family history questionnaire streamlines the referral process. The committee also agreed that laying out specific referral criteria would help the referring clinician and standardise the process.

The committee acknowledged that healthcare professionals and the general public are not sufficiently aware of which groups may be at risk which may lead to people not coming forward who would be eligible for testing. They therefore recommended that awareness raising should also be under the remit of commissioners and service providers. They discussed various public awareness initiatives for other conditions that may also be applicable for ovarian cancer (such as those related to familial breast cancer) and also noted that it could feature in continuing education of healthcare professionals. The agreed that this may improve early identification of those at risk.

The committee discussed, based on their experience, that some people such as those with physical, cognitive or sensory disabilities, some diverse ethnic groups as well as men, trans people and non-binary people may be under referred to genetic services. They agreed to recommend that commissioners and service providers should be responsible for equality and inclusiveness training, and information provision for healthcare professionals in primary and secondary care to address this.

Primary care services

The committee agreed that primary care healthcare professionals have no capacity to seek out potential index cases, however, in cases where for example a family history is known or where they are from an at-risk population they can make a referral to genetic services (see also the discussion on other referral criteria in evidence review D). Based on their experience, the committee listed the main responsibilities of primary care healthcare professionals such as providing information and support and referral to genetic services and/or other specialist services.

Genetic services

The committee agreed to list the main responsibilities of genetic services including providing information and support, pathogenic variant risk assessment, genetic counselling and testing, cascade testing of relatives, discussion of potential management options and referral to the familial ovarian cancer multidisciplinary team, so people know what to expect when referred. This would mainly include genetic counselling and genetic testing of people at risk of having a pathogenic variant without a personal history of epithelial ovarian cancer. However, the committee specified that it should be within the remit of genetic services to provide genetic counselling and genetic testing to those diagnosed with rare non-epithelial ovarian cancers (ovarian Sertoli–Leydig cell tumour, small cell carcinoma of the ovary hypercalcaemic type, ovarian sex cord tumour with annular tubules, embryonal rhabdomyosarcoma of the ovary or ovarian gynandroblastoma) – for the discussion of the list of cancers see evidence review I.

Gynaecology oncology multidisciplinary team

Based on the evidence which showed some important benefits of genetic testing and counselling where the gynaecology oncology team takes responsibility, the committee agreed that mainstream genetic counselling and testing of women with a histopathological diagnosis of epithelial ovarian cancer should be carried out by their gynaecology oncology multidisciplinary team. They agreed that in general the evidence indicated that counselling provided within the gynaecology oncology multidisciplinary team would be more efficient and faster for women with ovarian cancer to access than referral to genetics services.

Familial ovarian cancer multidisciplinary team

The committee discussed the management of people who carry a pathogenic variant and those who are above a risk threshold. The committee acknowledged the significant variation in practice in the way risk is managed for this population. To standardise practice and provide coordinated lifelong care for people at risk of familial ovarian cancer the committee agreed to list the responsibilities of the MDT and also a familial ovarian cancer multidisciplinary team approach consisting of members with expertise in clinical genetics, gynaecology and gynaecological oncology would be the most appropriate. This was also partly based on the evidence about the multidisciplinary management of people who are carriers of pathogenic variants, which showed better recruitment to clinical trials with a multidisciplinary one-stop follow-up clinic.

The committee agreed patients would require access to a range of different services during their lifetime which they do not currently always have direct access to. Psychology services may be needed if the person is distressed or is finding it impossible to reach a decision; fertility or menopause services would be needed when risk reducing surgery is being considered; breast and ovarian cancer services could be needed if cancer is suspected and colorectal services may be needed for people with Lynch syndrome They gave these as examples but did not rule out that others may be needed on a case by case basis. They therefore decided to recommend that there are agreed referral pathways to such specialist services through the familial ovarian cancer multidisciplinary team.

Cost effectiveness and resource use

There was no existing economic evidence identified for this review.

The committee noted the existence of variation in the referral criteria, the minimum dataset accepted prior to referral, and also practices among clinicians in primary and secondary care regarding whether and how to make a referral. Therefore, the recommendation in this area should help reduce such variation in practice. There was some discussion about family history questionnaires and it was noted that patients are generally responsible for their completion. It was agreed that an online referral form to specialist services could be completed within minutes, for example by GPs.

This recommendation may also result in an increased number of people accessing genetic services, potentially creating additional pressure on existing services. However, the committee explained that the costs associated with genetic testing and counselling are low compared with the potential benefits. Identifying people with pathogenic variants could significantly reduce their risk of cancer and associated costs.

There are various training programmes on equality and inclusiveness issues available for NHS staff. The recommendation for this will not require services to set up new training, create new information resources nor is it expected to require additional resources to implement.

The committee discussed primary care and genetic services’ responsibilities for people at risk of familial ovarian cancer. This recommendation represents current practice and will not require additional resources to implement. Similarly, the committee explained that people diagnosed with epithelial ovarian cancer would be under the care of gynaecology oncology multidisciplinary team who would be initiating genetic counselling and testing which is current practice across services. Reducing these variations will also help to ensure that people have equal access to genetic testing.

The committee discussed familial ovarian cancer multidisciplinary teams’ composition, roles and responsibilities. These teams may not exist in every cancer centre and recommendations on this may represent a change in practice for some services. Most cancer services are expected to have access to psychological services, menopause services etc. This recommendation is about ensuring that multidisciplinary teams have links to existing specialist services and do not require establishment of new services.

The committee noted that support services should have the capacity to meet the referrals from ovarian cancer services. However, the committee highlighted that some services have staff shortages, which may impact the implementation of this recommendation. It was also acknowledged that due to the more streamlined organisation of services for people with familial ovarian cancer, more people might access support services earlier, potentially creating additional pressure on the services. Nevertheless, the committee agreed that under resourcing of services should not prevent them making recommendations on access to such services.

There was further discussion about how these multidisciplinary teams are set up. They explained that while access to specialists is essential and the overall care is coordinated by them, physical co-location of these specialists in a single clinic is not required. The committee was of a view that setting up familial ovarian cancer multidisciplinary teams, in cases where they are currently lacking, is unlikely to require significant resources. They noted that any additional costs associated with setting up these teams would be outweighed by the benefits they offer, including coordinated and timely access to appropriate care, such as risk-reducing surgery. These teams can effectively reduce individuals’ cancer risk and associated care costs.

Other factors the committee took into account

The committee discussed that there were some configuration of service models which were not included in this review because they were not comparative. They mentioned the mainstream genetic testing pathway in which testing was undertaken by the trained cancer team with cascade testing to relatives performed by the genetics team (George et al. 2016). This testing pathway showed that the mainstream BRCA testing required fewer appointments, fewer referrals to genetics teams and was quicker overall. However, this study did not impact the recommendations.
