Norwegian Adenomyosis Study I (NAPPED I)

April 4, 2017 updated by: Tina Tellum, Oslo University Hospital

Norwegian Adenomyosis Study: Pathophysiology, Peristalsis, Expression Profiling and Diagnostics, Part I

Adenomyosis is characterized by the appearance of endometrial cells in the muscular layer of the uterus. It affects about 15-20% of the female population.

The symptoms of adenomyosis are heavy menstrual bleedings and painful menstruation (dysmenorrhea) and in addition chronic pelvic pain. Subfertility and infertility have been correlated with adenomyosis.

Parity, age and uterine abrasion increase the risk of adenomyosis. Hormonal factors such as local hyperestrogenism and elevated levels of prolactin have been identified, but autoimmune and mechanical factors are also hypothesized.

Regarding treatment, the most effective measure is hysterectomy. As this is a very drastic measure in younger women, levonogestrel-releasing intrauterine devices, Gonadotropin releasing hormone (GnRH)-analogues, Danazol, uterine embolization and endometrial ablation have been tried, but studies are few in number, retrospective, and have small sample sizes.

Adenomyosis has so far not been subject to extensive research efforts. The pathogenesis of adenomyosis remains still unclear, there are not many satisfying treatment options and diagnostics include mostly magnetic resonance imaging (MRI) and histology.

The investigators designed a series of 3 studies with a broad approach in understanding adenomyosis. This is part 1.

Detailed Description

Diagnosis of Adenomyosis with 3D and 2D transvaginal ultrasound. Prospective study of a consecutive series of 101 patients that are scheduled for hysterectomy and suffer from bleeding disorders, chronic pelvic pain, dysmenorrhea or dyspareunia. All patients will undergo transvaginal 2D- ultrasound, 3D-ultrasound and power doppler (PD)-ultrasound (TVU), magnetic resonance imaging of the pelvic organs (MRI) and hysterectomy.

We will investigate the specificity and sensitivity of 3D and 2D transvaginal ultrasound in the diagnosis of adenomyosis and compare data with MRI and histopathology, which is the gold standard by today. In addition, we will collect anamnestic information that might point to risk factors or connections to prior obstetrical complications and medicine use. In our study the pathologist will not be blinded to our ultrasound findings, and we want to investigate if this will raise the sensitivity of histology findings of adenomyosis.

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

21 years to 46 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Women referred to our clinic and volunteering to participate and that are registrated in Norway with a norwegian social security number.

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
Difference in sensitivity and specificity of 3D TVU and MRI; in percentage points (%)
Time Frame: within 4 weeks after 3D TVU
Sensitivity and specificity of 3D TVU in the diagnosis of adenomyosis compared to MRI.
within 4 weeks after 3D TVU

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
Positive and negative predictive value of 3D TVU in percent (%)
Time Frame: within 17 weeks after 3D TVU
Positive and negative predictive value of 3D TVU in diagnosis of adenomyosis. The histological examination is the end-point because it is still regarded to be the gold-standard in diagnosis of adenomyosis.
within 17 weeks after 3D TVU
Difference in sensitivity and specificity of 3D TVU and 2D TVU; in percentage points (%)
Time Frame: within 17 weeks after 3D TVU
The sensitivity and specificity of 3D TVU in the diagnosis of adenomyosis will also be compared to 2D TVU, in addition to MRI (see primary outcome measure).

Difference in max. thickness of junction zone, in millimeters (mm)
Time Frame: post ovulatory in any menstruational cycle prior to surgery, within 4 weeks after 3D TVU
