Papillary thyroid carcinoma: modified radical neck dissection improves prognosis

Area of Science:

• Oncology
• Surgical Oncology
• Endocrine Surgery

Background:

• Papillary thyroid cancer (PTC) is the most common thyroid malignancy.
• Neck dissection is a critical component in the surgical management of PTC.
• The extent of neck dissection, particularly modified radical neck dissection (MRND), requires careful consideration for optimal patient outcomes.

Purpose of the Study:

• To evaluate the survival benefit of modified radical neck dissection (MRND) in specific patient subsets with papillary thyroid cancer.
• To identify risk factors influencing outcomes in patients undergoing surgical treatment for papillary thyroid cancer.

Main Methods:

• Retrospective cohort study of 2966 patients treated between 1946 and 1991.
• Analysis included patients with primary tumors ≥1 cm undergoing curative treatment.
• Surgical approaches included MRND (72.1%), partial node excision (8.5%), and no node excision (19.4%).

Main Results:

• Univariate and multivariate analyses identified significant risk factors: sex, age, primary tumor size, extrathyroidal invasion, and nodal metastasis.
• A subset of patients demonstrated a survival advantage with MRND.
• Key predictors of outcome included age, tumor characteristics, and presence of metastasis.

Conclusions:

• Modified radical neck dissection (MRND) offers survival benefits for select papillary thyroid cancer patients.
• Patients with nodal metastasis, extrathyroidal tumor invasion, and women over 60 years old are identified as beneficiaries of MRND.
• These findings support tailored surgical approaches in managing papillary thyroid cancer based on individual risk factors.
