STAGE-MTC Trial Thyroid Lobectomy With Ipsilateral Central Neck Dissection

2026年5月27日 更新者：Jonsson Comprehensive Cancer Center

STAGE-MTC Trial Thyroid Lobectomy With Ipsilateral Central Neck Dissection for the Treatment of Sporadic Medullary Thyroid Cancer, STAGE-MTC Trial

This clinical trial studies how well thyroid lobectomy with ipsilateral central neck dissection works to treat medullary thyroid cancer (MTC) in patients without a germline RET mutation (sporadic). Currently, sporadic and germline RET (rearranged during transfection) mutation positive MTCs that are limited to the thyroid are managed in the same way, complete surgical removal of the entire thyroid gland (total thyroidectomy) with surgical removal of lymph nodes and other tissues on both sides of the neck (bilateral central neck dissection). Total thyroidectomy and bilateral central neck dissection carry a high risk of complications, and total thyroidectomy requires patients to take lifelong thyroid hormone replacement therapy, which can impact quality of life. Research has shown that patients with sporadic MTC do not have a high risk of developing MTC in the remaining normal thyroid tissue and that they may be able to be managed differently than patients with germline RET mutations. Thyroid lobectomy with ipsilateral central neck dissection is a surgical procedure which removes only the lobe of the thyroid gland that is affected by cancer as well as the lymph nodes and other tissues from the affected side of the neck. Thyroid lobectomy with ipsilateral central neck dissection may be a safer, more tolerable, and/or more effective way to treat sporadic MTC.

詳細な説明

PRIMARY OBJECTIVE:

I. To determine the number of patients that have no biochemical evidence of persistent medullary thyroid cancer following thyroid lobectomy and ipsilateral prophylactic central neck dissection alone versus number of patients with biochemical evidence of persistent MTC that requires completion thyroidectomy.

SECONDARY OBJECTIVES:

I. Determine the short-term oncologic treatment outcomes of a novel staged approach to sporadic medullary thyroid cancer, defined by response to therapy category (excellent, biochemical incomplete, structural incomplete).

II. Determine the prevalence of undetected foci of medullary thyroid cancer in contralateral thyroid lobe and contralateral lymph nodes.

OUTLINE:

Patients undergo thyroid lobectomy with unilateral central neck dissection on study. Patients then undergo blood sample collection for calcitonin and carcinoembryonic antigen (CEA) monitoring with neck ultrasound and/or gallium-68 (Ga-68) or fludeoxyglucose F-18 (FDG) positron emission tomography (PET)/computed tomography (CT) at 3 and 6 month follow-ups. Patients with no biochemical or imaging evidence of persistent disease undergo routine cancer surveillance. Patients with either of the following: 1) Elevated or rising calcitonin and/or CEA plus imaging suggestive of residual disease in the contralateral thyroid lobe or contralateral cervical lymph nodes, or 2) Elevated or rising calcitonin and/or CEA with negative imaging for an alternate source, consistent with biochemical evidence of residual disease in the remaining thyroid lobe, may undergo completion thyroidectomy and/or contralateral neck dissection during follow up. Patients also undergo additional blood sample collection, neck ultrasound, and/or Ga-68 or FDG PET/CT throughout the study.

After completion of study intervention, patients are followed up at day 14 and months 3, 6, 12, 18, and 24.

Exclusion Criteria:

  • Indication for total thyroidectomy unrelated to medullary thyroid cancer:

Exact 95% confidence intervals will be provided. Exploratory subgroup analyses (e.g., stratified by baseline calcitonin level, tumor size, or nodal status) may be conducted to generate hypotheses but will not be powered for formal inference.

メジャーの説明
時間枠
Short-term oncologic outcomes
時間枠：At 12 months
Short-term oncologic outcomes will be categorized according to the American Thyroid Association ATA) "response to therapy" framework, adapted for medullary thyroid carcinoma. Categories will include: Excellent response: Normal calcitonin and CEA with no structural evidence of disease on imaging; Biochemical incomplete response: Abnormal calcitonin and/or CEA without structural evidence of disease; Structural incomplete response: Evidence of structural disease on imaging, regardless of biochemical status. Will be summarized descriptively. Exact 95% confidence intervals will be reported. Comparisons to baseline disease features (e.g., initial calcitonin levels, tumor size, lymph node involvement) may be explored but will be considered hypothesis-generating only.
At 12 months
Prevalence of occult contralateral disease
時間枠：Perioperative/Periprocedural
Among patients who undergo completion thyroidectomy and/or contralateral neck dissection, will assess the prevalence of previously undetected foci of medullary thyroid cancer in the contralateral thyroid lobe and contralateral cervical lymph nodes. Pathologic findings will be reported as proportions with corresponding exact 95% confidence intervals.
