Radical or simple hysterectomy with bilateral pelvic and/or aortic lymphadenectomy was performed after SLN mapping.Results Overall, 81 women (64 women with endometrial cancer and 17 women with cervical cancer) underwent surgery, including SLN mapping. Sixty-five patients (80%) underwent minimally invasive surgery. The overall detection rate was 84% (34 of 38) and 100% (43 of 43) for MB and ICG, respectively (P = 0.041). Bilateral SLN detection was higher in the ICG group than in the MB group (88% vs 50; P = 0.002). Eleven patients (13.5%) were found to have positive nodes with at least 1 positive SLN. The sensitivity and negative predictive value of SLN were 100%.Conclusions Real-time florescence mapping with ICG shows better overall detection rate and bilateral mapping than MB alone. In our pilot study, the differences are statistically significant. The higher number of bilateral mapping of ICG may increase the quality of life and recovery of women by reducing the need for complete lymphadenectomy.
