Sentinel lymph node mapping with indocyanine green using SPY-PHI in open radical hysterectomy or trachelectomy
To evaluate the detection rate of at least one sentinel lymph node (SLN) in patients with early cervical cancer who underwent open radical hysterectomy or trachelectomy using indocyanine green (ICG) with the SPY Portable Handler Imager (SPY-PHI) system. We retrospectively reviewed patients with cervical cancer FIGO 2018 stage IA1 with lymphovascular invasion up to stage IIIC1p who underwent SLN mapping and open radical hysterectomy or trachelectomy from March 2018 through August 2022 at The University of Texas MD Anderson Cancer Center. ICG was the only tracer used with the SPY-PHI system. Patient demographics, surgical approach, and tumor factors were analyzed. Overall detection, bilateral detection, and empty lymph node packet rates were determined. A total of 106 patients were included. Ninety-four (88.7%) patients underwent open radical hysterectomy and 12 (11.3%) open radical trachelectomy. Median age was 40 years (range, 23-71). Median body mass index was 28.8 kg/m SLN mapping using ICG with the SPY-PHI system in open radical hysterectomy or trachelectomy is reliable and results in high overall and bilateral detection rates in patients with early cervical cancer.
