Abstract
OBJECTIVE: We report the long-term results of the SENTI-ENDO study evaluating the impact of sentinel lymph node (SLN) biopsy on management and survival in patients with early stages of endometrial cancer (EC). METHODS: Patients with FIGO stage I-II EC underwent pelvic SLN biopsy after cervical dual injection (technetium and patent blue) and systematic pelvic node dissection. This study is a secondary endpoint reporting the long-term recurrence free survival (RFS) and the impact of the SLN procedure on adjuvant therapies. RESULTS: The median follow-up was 50 months (range: 3-77 months). Eighteen of the 125 patients (14.4%) experienced a recurrence. The 50-month recurrence-free survival (RFS) was 84.7% with no difference between patients with and without detected SLN (p = 0.09). Among patients with detected SLN (111), no difference in RFS was observed between those with and without positive SLN (p = 0.5). In the whole population, adjuvant therapy was performed in low-, intermediate- and high-risk groups in 31 of 64 patients (48.4%), 28 of 37 patients (75.7%) and 14 of 17 patients (82.3%), respectively (p = 0.0001). For the 111 patients with detected SLN, EBRT was performed in 27 of the 89 with negative SLN and in 11 of the 14 with positive SLN (p = 0.001). Chemotherapy was performed more frequently in patients with positive SLN (6/12, 50%) than in patients with negative SLN (7/56, 12.5%) (p = 0.009). CONCLUSIONS: Our results support the impact of SLN biopsy on surgical management and indications for adjuvant therapies. Further studies are required to assess the clinical impact of the SLN biopsy in early stage EC.
