Regional lymph node metastases in well-differentiated thyroid carcinoma

Area of Science:

• Oncology
• Surgical Oncology
• Head and Neck Surgery

Background:

• Thyroid cancer frequently involves regional lymph nodes, impacting prognosis.
• Accurate assessment of lymph node metastasis is crucial for treatment planning.

Purpose of the Study:

• To evaluate the incidence of regional lymph node metastasis in thyroid cancer patients.
• To determine the optimal surgical approach for lymph node dissection in thyroid cancer.

Main Methods:

• Retrospective analysis of 171 thyroid cancer patients undergoing thyroidectomy and lymph node dissection.
• Assessment of lymph node metastasis in central and lateral cervical compartments.

Main Results:

• Regional lymph node metastasis rates were 57% for minimal and 84% for ordinary thyroid cancer.
• High rates of metastasis were observed in both central and lateral jugular compartments.
• Bilateral metastases were frequent in patients with extensive disease, isthmus involvement, or clinically detected contralateral nodal disease.

Conclusions:

• Modified radical neck dissection in the ipsilateral neck is recommended for thyroid cancer patients with high metastasis rates.
• Bilateral modified radical neck dissection is advised for patients with widespread bilateral nodal involvement.
