Sentinel lymph node biopsy alone compared to systematic lymphadenectomy in patients with uterine carcinosarcoma

To assess survival among patients diagnosed with uterine carcinosarcoma (CS) who underwent sentinel lymph node (SLN) biopsy alone vs. systematic lymph node dissection (LND). We identified newly diagnosed CS patients who underwent primary surgical management from January 1996–December 2019. The SLN cohort underwent SLN biopsy alone with bilateral SLNs identified. The systematic LND cohort did not undergo SLN biopsy. Ninety-nine patients underwent SLN biopsy, and 100 patients underwent systematic LND. There was no difference by age, stage, body mass index, myoinvasion (
