• 1 other identifier: HREBA.CC-25-0488
• Study Type: observational
• Target: 85
• Locations: 0 countries
• Sites: N/A

Brief Summary

The purpose of this study is to learn whether having Thyroid GuidePx® test results available before treatment may help patients with papillary thyroid cancer and doctors make better-informed treatment decisions.

Conditions

Papillary Thyroid Cancer; Papillary Thyroid Carcinoma

Outcome Measures

Primary Outcomes (1)

• Decision impact

  Decision impact is defined as any change in treatment decision based on the Thyroid GuidePx® test results, including changes in surgical approach, reduction of unnecessary treatments, and addition of recommended treatments. Decision impact is measured using study-specific clinician and patient questionnaires administered before and after test results are available. Clinician decision impact is assessed by comparing treatments considered prior to testing with treatments recommended after review of test results, as well as clinician agreement with the statement "The test helped to make a treatment decision" rated on a 5-point Likert scale. Patient decision impact is assessed by patient report of whether the test helped them make a treatment-related decision (Yes/No) and the degree to which the test contributed to their care. A copy of the questionnaires can be uploaded as required (study document upload is currently disabled).
