About this study

This study evaluates a thyroid-function-preserving alternative to routine total thyroidectomy for bilateral papillary thyroid carcinoma (PTC). Eligible adults undergo remote-access gas-less axillo-breast endoscopic hemithyroidectomy with level VI dissection on the dominant side, followed by ultrasound-guided radiofrequency ablation (RFA) of a ≤7 mm contralateral focus during the same anesthesia. Outcomes include structural-recurrence-free survival, endocrine-function preservation, safety, and quality of life over 24 months.

Read the detailed description

Bilateral PTC traditionally prompts total thyroidectomy, exposing patients to lifelong thyroxine replacement and a 1 - 3 % risk of permanent hypocalcemia. Building on a pilot cohort of 11 patients treated from June 2018 to September 2024 that showed no structural recurrence, no permanent RLN palsy, and preserved endocrine function after a median 17-month follow-updraft_Proof_hi, we launch a multicenter registry to confirm oncologic adequacy and functional benefits. Intervention: endoscopic hemithyroidectomy (dominant lobe) via gas-less axillo-breast approach plus central-neck dissection; then contralateral lesion RFA with a 17-gauge 0.7-cm active-tip electrode at 40 W (moving-shot). Follow-up at 1, 6, 12, 18, and 24 months includes ultrasound, serum Tg, calcium, PTH, and QoL instruments. Long-term surveillance continues annually to five years.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Endoscopic Hemithyroidectomy with Central-Neck DissectionProcedure or surgery

    Gas-less axillo-breast approach (trans-axillary + peri-areolar), carbon-dioxide-free working space, removing dominant thyroid lobe plus level VI lymph nodes; intra-operative neuromonitoring used throughout.

  • Ultrasound-Guided Radiofrequency Ablation of Contralateral NoduleProcedure or surgery

    17-gauge internally-cooled electrode, 0.7 cm active tip, power 40 W; moving-shot technique under real-time ultrasound until hyperechoic halo fully covers ≤ 7 mm papillary microcarcinoma ≥ 2 mm from posterior capsule; same anesthesia session as surgery.

What is being measured

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

  1. Structural Recurrence-Free Survival

    Proportion of participants without local, regional, or distant structural recurrence confirmed by imaging ± cytopathology.

    Measured: 24 months

  2. Endocrine-Function Preservation

    Participants alive and free from lifelong levothyroxine therapy and permanent hypocalcemia (serum Ca ≥2.1 mmol/L without supplementation).

    Measured: 24 months

Secondary outcomes (4)
  1. Permanent RLN Palsy Incidence

    Laryngoscopy-confirmed vocal-fold mobility disorder persisting ≥6 months.

    Measured: 12 months

  2. Permanent Hypocalcemia Incidence

    Need for calcium/vit-D >6 months after surgery.

    Measured: 12 months

  3. Nodule Volume Reduction Rate

    Percentage reduction of ablated nodule volume on ultrasound.

    Measured: 12 months

  4. Procedure-Related Adverse Events

    Any CTCAE v5.0 Grade ≥3 event within 30 days.

    Measured: 30 days

Questions about this trial

What is this clinical trial studying?

A study testing Endoscopic Hemithyroidectomy with Central-Neck Dissection and Ultrasound-Guided Radiofrequency Ablation of Contralateral Nodule in people with Thyroid Neoplasms and Carcinoma, Papillary, run by Fujian Medical University at 1 site in China.

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 5 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 3 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Bo Wang Professor, MD (+13959123550, wangbo@fjmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Structural Recurrence-Free Survival (time frame: 24 months). The study lists 2 primary outcomes in all. 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 3 Jul 2025.
