Pelvic lymph node dissection (PLND) in cervical cancer patients did not remove all MRI-detected lymph nodes, with 14% left behind. Further research is needed to assess MRI

Area of Science:

  • Gynecologic Oncology
  • Radiology
  • Surgical Pathology

Background:

  • Pelvic lymphadenectomy is the standard for diagnosing and treating lymphatic metastases in gynecologic cancers.
  • Accurate lymph node staging is crucial for effective cervical cancer treatment.

Purpose of the Study:

  • To determine if all lymph nodes identified by MRI were removed during systematic pelvic lymph node dissection (PLND) in cervical cancer patients.

Main Methods:

  • 21 cervical cancer patients underwent pre- and post-surgical MRI.
  • All patients had histopathologically confirmed negative lymph nodes for metastasis.

Main Results:

  • Presurgical MRI detected an average of 10 pelvic lymph nodes per patient.

Published on: December 30, 2025

  • Post-surgery MRI revealed an average of 1 unremoved lymph node per patient (14% of total detected nodes).
  • Surgery removed significantly more nodes (average 21) than detected by MRI, with half of remaining nodes in the obturator region.

    • Conclusions:

    • A significant percentage (14%) of MRI-detected lymph nodes were not removed during PLND.
    • The utility of pre-surgical MRI for pathological lymph node detection requires further investigation.
