Summary
This summary is machine-generated.

Cervical lymph node dissection is recommended for papillary thyroid cancer (PTC) patients with tumors 1 cm or larger due to high metastasis rates. Nearly half of PTC cases show cervical metastasis, particularly with increased tumor size and high-risk factors.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Endocrine Surgery

Background:

  • Controversy exists regarding the necessity of cervical lymph node dissection in papillary thyroid cancer (PTC) surgical treatment.
  • Understanding appropriate indications for this procedure is crucial for optimizing patient outcomes.

Purpose of the Study:

  • To investigate the indications for cervical lymph node dissection in PTC surgery.
  • To analyze metastasis rates in relation to tumor size and lymph node involvement.

Main Methods:

  • Retrospective analysis of clinical and pathological data from 2108 PTC patients treated between 2015 and 2018.
  • Comparison of outcomes between patients undergoing total thyroidectomy with central lymph node dissection versus those with additional cervical lymph node dissection.

Main Results:

  • Overall average metastasis rate was 57.23%, with 48.97% for papillary thyroid microcarcinoma (PTMC).
  • Central and lateral cervical lymph node metastasis occurred in 74.44% of cases.
  • Tumors ≥1 cm showed a significantly higher cervical metastasis rate (56%), increasing with tumor diameter.

Conclusions:

  • Papillary thyroid cancer exhibits a high metastasis rate (>50%), with nearly half involving cervical lymph nodes.
  • Cervical lymph node dissection is indicated for PTC patients with tumors 1 cm or greater, especially those with high-risk factors.
