Clinical Study of Biokinetic Model of Iodine-131 in Total(Near) Thyroidectomy Patients.

February 22, 2022 updated by: Far Eastern Memorial Hospital

Thyroid cancer patients who have undergone total thyroidectomy, postoperative iodine 131 treatment to ablation residual thyroid tissue, is the current clinical practice. The effective half-life of the iodine 131 in the human body and in vivo exposure dose can be assessed by the in vivo kinetic model published by ICRP, but this model is based on standard healthy people and can not be corrected for patients undergoing total thyroidectomy.

In this study, the investigators will use the actual clinical data to revise the biokinetic model of iodine-131 in patients with total thyroidectomy.

Detailed Description

Methods Patients:All patients undergoing thyroidectomy and are about to be treated with iodine 131 30mCi will be invited to join the study. Exclusion with gastrointestinal surgery.

Preparation:The patient of this study, their medication and diet and other matters needing attention, are in accordance with the original to accept iodine -131 30mCi treatment of the standard treatment.

Imaging Protocol:After oral administration of iodine 131, patients must undergo whole body scan, for 1 hour, 4 hours, 24 hours, 48 hours, 72 hours, 168 hours, respectively. Image collection will use GE Infinia Hawkeye 4 SPECT / CT with high energy general purpose collimator. The imaging parameters use the original I-131 whole body scan protocol.

Expected results:Image data is further analyzed by MATLAB software to obtain iodine 131 in the body of individual organs of the biological half-life and path strength percentage. This analysis can revise the iodine -131 biokinetic model of patients with total thyroidectomy, providing more accurate calculations and subsequent studies.

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.

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
The I-131 distributed among the internal organs after the dose administration can be thoroughly analyzed according to a revised MATLAB program.
Time Frame: After oral administration of iodine 131, patients must undergo whole body scan, for 1 hour, 4 hours, 24 hours, 48 hours, 72 hours, 168 hours, respectively.
Image data is further analyzed by MATLAB software

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
