Summary
Papillary thyroid carcinoma frequently metastasizes to lymph nodes. Surgical treatment involves total thyroidectomy with lymphadenectomy, with ipsilateral dissection indicated for specific cases.
Area of Science:
- Endocrinology
- Oncology
- Surgical Pathology
Context:
- Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy.
- Increasing incidence of PTC necessitates effective diagnostic and treatment strategies.
- Lymphatic metastasis is a key feature of PTC progression.
Purpose:
- To diagnose patients with papillary thyroid carcinoma.
- To compare TNM staging with lymph node metastasis findings.
- To evaluate surgical outcomes and complications.
Summary:
- A retrospective study analyzed 1,353 patients (2005-2008), identifying 220 thyroid malignancies, including 180 PTC cases.
- TNM staging revealed varying tumor sizes, with multifocal PTC in 23.3% of cases.
- Lymphadenectomy revealed metastasis in 113 of 351 removed nodes, with low rates of permanent nerve paresis.
Impact:
- Establishes total thyroidectomy with cervicocentral lymphadenectomy as standard surgical care for PTC.
- Provides criteria for ipsilateral lymphadenectomy based on sonographic findings or tumor size (T2).
- Contributes to understanding PTC metastasis patterns and refining surgical management guidelines.
