Multifocality, especially with three or more foci, predicts central lymph node metastasis in papillary thyroid microcarcinoma. This finding aids in identifying high-risk patients for prophylactic central neck lymph node dissection.
Area of Science:
- Endocrinology
- Oncology
- Surgical Pathology
Background:
- Papillary thyroid microcarcinoma (PTMC) risk stratification is crucial.
- Identifying predictors for central lymph node metastasis (CLNM) is essential for treatment planning.
Purpose of the Study:
- To evaluate multifocality as a predictive factor for CLNM in PTMC.
- To identify patients at high risk for CLNM.
Main Methods:
- Retrospective analysis of PTMC patients undergoing thyroidectomy and lymph node dissection.
- Multivariate analysis to determine independent predictors of CLNM.
Main Results:
- Multifocality, age, sex, tumor size, extrathyroidal extension, and nodular goiter were associated with CLNM.
- Multifocality independently predicted CLNM.
- Odds ratio for CLNM was 2.978 for patients with ≥3 tumor foci (P<0.001).
Conclusions:
- Multifocality with ≥3 foci is an independent predictor of CLNM in PTMC.
- Assessment of multifocality is recommended for selecting patients for prophylactic central neck lymph node dissection.
- Patients with multifocality may benefit from more radical treatment approaches.

Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

The papillary layer is made of loose, areolar connective tissue, which means the collagen...
