Lymph node dissection (LND) in uterine leiomyosarcoma (ULMS) surgery did not improve disease-free or overall survival. This study found no significant survival benefit for patients undergoing LND compared to those who did not.

Area of Science:

  • Gynecologic Oncology
  • Surgical Oncology
  • Pathology

Background:

  • Uterine leiomyosarcoma (ULMS) is a rare uterine malignancy.
  • The role of lymph node dissection (LND) in the surgical management of ULMS remains controversial.
  • Assessing LND impact on survival outcomes is crucial for treatment optimization.

Purpose of the Study:

  • To evaluate the effect of lymph node dissection (LND) on disease-free survival (DFS) and overall survival (OS) in women with uterine leiomyosarcoma (ULMS).
  • To compare survival outcomes between ULMS patients who underwent LND and those who did not.

Main Methods:

  • A multicentric retrospective study (SARCUT) involving 390 ULMS patients across European countries.
  • Comparison of survival rates between patients with and without LND.

  • Matched-pair subanalysis of 116 patients (58 pairs) matched for key clinical and pathological variables.

    • Main Results:

    • In the overall cohort, 5-year DFS was significantly higher in the no-LND group (57.7%) versus the LND group (33.0%) (p=0.007).
    • No significant difference in 5-year overall survival (OS) was observed between the LND and no-LND groups in the overall cohort (64.3% vs. 64.6%).
    • The matched-pair subanalysis showed no statistically significant differences in either DFS or OS between the LND and no-LND groups.

    Conclusions:

    • Lymph node dissection (LND) in women diagnosed with uterine leiomyosarcoma (ULMS) does not appear to impact disease-free or overall survival.
    • The findings suggest that LND may not be beneficial for ULMS patients in terms of survival outcomes.
    • Further research may be warranted to confirm these findings in larger, prospective studies.
