Trial summary

Our objective is to determine if the combination of simple ultrasound features (IOTA simple rules) and a new biomarker (HE4) together with a common tumour marker (CA 125) can accurately predict ovarian cancer in women found to have a pelvic mass on ultrasound. Read more about this study

About this study

Official title: The Use of a New Biomarker, HE4, in Combination With Simple Ultrasound Rules in the Prediction of Malignancy in a Pelvic Mass Detected on Ultrasound

Our objective is to determine if the combination of simple ultrasound features (IOTA simple rules) and a new biomarker (HE4) together with a common tumour marker (CA 125) can accurately predict ovarian cancer in women found to have a pelvic mass on ultrasound. The investigators hypothesize that the use of two biomarkers (HE4 and CA 125) in a mathematical algorithm (Risk of Malignancy Algorithm, ROMA) can be used to predict malignancy in a pelvic mass which has indeterminate ultrasound features. This is a prospective cohort study involving women undergoing operation for a pelvic mass. 720 women scheduled to have an operation to remove a pelvic mass would be recruited from 3 hospitals (QMH, UCH and PYNEH). Pre-operatively, each woman will have an ultrasound assessment using the IOTA simple rules criteria and have blood taken for tumour markers HE4 and CA 125. In women where IOTA ultrasound rules are inconclusive, 2 strategies for prediction will be compared - calculation of risk by ROMA (Strategy A) vs referral for an expert ultrasound (Strategy B). These pre-operative risk predictions will be correlated with the final pathology found at the operations.

Main outcome measures include the sensitivity, specificity, positive and negative predictive powers for Strategy A compared to Strategy B. Sensitivity and specificity will be compared using the McNemar test. Area Under the ROC Curve (AUC) will be calculated and compared using the Delong method for the 2 strategies.

The investigators expect AUC of both strategies will be similar. This would suggest that ROMA can replace expert ultrasound in the pre-operative prediction of ovarian cancer.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. sensitivity, specificity and predictive powers

    The group of women with inconclusive IOTA assessment will undergo further assessment by both tumour markers assessment by ROMA (Strategy A) and expert ultrasound (Strategy B). The prediction of risk of malignancy (high or low) will be correlated with the final histopathology result from the surgery. The sensitivity, specificity and predictive powers for the 2 strategies will be compared.

    Measured: 3 months after last subject enrolled

Secondary outcomes (3)
  1. Best method for predicting malignancy in pelvic mass in HK

    The sensitivity, specificity and predictive powers for 4 different predicting methods - (i) IOTA simple rules followed by ROMA (if IOTA inconclusive), (ii) IOTA simple rules followed by expert ultrasound assessments (if IOTA inconclusive), (iii) ROMA, or (iv) RMI will be compared.

    Measured: 3 months after last subject enrolled

  2. Accuracy of these 4 different prediction methods in different hospital settings

    The sensitivity, specificity and predictive powers for these 4 different prediction methods for the 3 hospitals will be compared and factors influencing the accuracy will be explored.

    Measured: 3 months after last subject enrolled

  3. Performance of IOTA simple rules followed by ROMA (if IOTA inconclusive) in different histological subtypes

    Since the tumour markers assessed by ROMA may be more commonly raised in some subtypes (eg serous adenocarcinoma) compared to other subtypes (eg mucinous adenocarcinoma), it is possible that the performance of IOTA followed by ROMA may differ in different histological subtypes. The final histological subtypes will be obtained from the pathology reports from the surgery. The sensitivity and specificity of IOTA followed by ROMA will be compared amongst the different major histological subtypes.

    Measured: 3 months after last subject enrolled

Questions about this trial

What is this clinical trial studying?

An observational study of Pelvic Mass, run by The University of Hong Kong at 3 sites in Hong Kong.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 11 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

sensitivity, specificity and predictive powers (time frame: 3 months after last subject enrolled). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jun 2021.
