RESUMEN

OBJECTIVES: Sentinel lymph node detection (SLND) has not yet displaced lymphadenectomy, but it is a desired supplementary technique in cervical cancer surgery. The aim of our study was to identify the sources of SLND failure while performing the procedure by injecting blue dye (BD) into the cervix in cases of early-stage cervical cancer (ECC). MATERIAL AND METHODS: We analyzed 27 consecutive ECC patients (FIGO IA2-IB1) who underwent hysterectomy with SLND and systematic lymphadenectomy between October 2011 and June 2014. The main inclusion criterion was at least unilateral SLND by BD. Predictors of either unilateral or bilateral staining were identified using multinomial logit models and a decision tree. RESULTS: Overall, bilateral staining was achieved in nine patients (33%). Among the factors analyzed, BMI > 23.5 kg/m2 was the only factor negatively affecting the quality of SLND using BD (p < 0.02) in the univariable multinomial logit model. All patients with BMI < 23.5 kg/m2 and depth of invasion ≥ 15 mm had unilateral mapping. CONCLUSIONS: Both obese and overweight patients are unlikely to achieve optimal SLN staining with BD alone. Although some possible reasons are discussed, we believe that further studies are needed to clarify the specific limitations of other dyes currently in use.
