Pilot Study: Can Ultrasound Guided Biopsy be Used as an Alternative to Hysteroscopy?

October 4, 2024 updated by: Imperial College London

Pilot Study: Can Ultrasound Guided Biopsy be Used as an Alternative to Hysteroscopy in the Detection of Endometrial Cancer?

Aim: Assess accuracy of histological diagnosis using ultrasound guided biopsy for women with suspected endometrial cancer (as an alternative to hysteroscopy guided biopsy).

All women presenting to clinic with suspected endometrial cancer will have an internal ultrasound. If the endometrial lining is thickened an endometrial biopsy will be performed. This can sometimes be done in an outpatient clinic, or sometimes a hysteroscopy and biopsy is needed (on a different day). Hysteroscopy guided biopsy has the advantage of enabling the clinician to perform directed biopsies under vision.

Ultrasound guided biopsy is a ubiquitous procedure when used elsewhere in the body however it is not routinely used in this context. It does have the advantage of being easily performed on the same day as the first consultation. In this pilot study the diagnostic ability and tolerability of ultrasound guided biopsy of women with suspected cancer will be assessed as an alternative to hysteroscopy guided biopsy.

Detailed Description

Aims: Assess accuracy of histological diagnosis using ultrasound guided biopsy for women with suspected endometrial cancer (as an alternative to hysteroscopy guided biopsy).

Background:

Endometrial cancer is a tumour originating in the endometrium (womb lining); it is the most common gynaecological cancer in the UK. Although routine management for these women does vary, in general a screening test is performed, typically a pelvic (internal) ultrasound to assess the endometrium (womb lining). In cases where the endometrial thickness is above the threshold for investigation - an endometrial biopsy (sampling cells from the womb lining) is indicated. The biopsy can be taken blindly or under scan or hysteroscopic guidance. Hysteroscopy, the insertion of a small camera into the womb to visualise the womb lining allows direct visualization of the cavity. This usually occurs at a separate consultation in an outpatient setting or under general anaesthesia.

In theory an ultrasound-guided biopsy using a very fine Bettocchi forceps could be used instead of hysteroscopy- guided biopsies of the endometrium. The technique of ultrasound-guided biopsy is ubiquitous when used elsewhere in the body. It is frequently used to provide histological diagnosis of pelvic masses, (presumed ovarian origin), both abdominally (scanning of the tummy) and transvaginally (internally). Potentially ultrasound guided biopsies could be used as a cheaper, faster and less painful alternative to a hysteroscopy directed biopsies. This pilot study will be the first to assess the diagnostic ability of ultrasound guided biopsy in the assessment of women with suspected endometrial cancer.

The study:

All women will receive a pelvic (internal) ultrasound as per routine care. If the endometrium (womb lining) is thickened >4mm on ultrasound they will require an endometrial biopsy. Usually this will be a pipelle. In cases where the pipelle biopsy cannot be performed in clinic due to poor tolerance, insufficient material or focal lesions a hysteroscopy guided biopsy will be required (local or GA).

In this case, the patients will be offered an ultrasound (USS) guided biopsy in the first instance, this will be performed at the same time in clinic. The biopsy will be taken under scan guidance using a very fine forceps such as Bettochi forceps. These forceps are used routinely during hysteroscopy so whilst the instruments are common the application is novel. The biopsy results of this will be sent for standard histology. If the results are inadequate patients will be sent for standard hysteroscopy and biopsy. Patients will also be asked to assess tolerability of the procedure using a visual analogue score.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

All women presenting to rapid access gynaecology clinic with postmenopausal bleeding or intermenstrual bleeding or referred with a confirmed diagnosis of endometrial cancer.

Exclusion criteria:

Anyone lacking capacity. <18years old. Pregnant.

Other: Women needing endometrial biopsy
All women who would be offered hysteroscopy guided biopsy as standard of care will be offered ultrasound guided biopsy first.

For women needed a hysteroscopy guided biopsy as part of routine standard of care, women will now receive an ultrasound guided biopsy first

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants Whose Sample Was Successfully Analysed by Histological Diagnosis
Time Frame: 1.5 years
All samples taken using ultrasound guided biopsy were analysed by histology lab. If they had sufficient tissue to give a diagnosis (benign, pre-malignant or malignant) this was deemed successful. It is deemed successful if there was sufficient tissue to give a histological analysis. So overall there will be a percentage success rate (number of tissue samples sufficient/number of tissue samples taken). Each patient would have had one sample.
1.5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Patient Satisfaction of Ultrasound Guided Biopsy by Questionnaire
Time Frame: 1.5 years
Visual analogue score will be given to patients post procedure to assess tolerability of the procedure. The full score scale ranges from 0 to 10 that means from no pain (0) to worst pain they ever had (10).
