BackgroundThe primary objective of this study was to elucidate the impact of sentinel lymph node (SLN) mapping and biopsy techniques on the clinical outcomes of women with early primary cervical cancer.MethodsAll consecutive women with clinically determined stage I-IIA cervical cancer who underwent lymph node assessment with either SLN mapping or conventional pelvic/para-aortic lymphadenectomy were reviewed.ResultsWomen in the SLN group (n=33) had fewer total dissected pelvic nodes (8.3±5.9 versus 17.4±7.7, p<0.001), less intraoperative blood loss (513±332mL versus 1228±1170mL, p<0.001), a shorter length of hospital stay (7.1±2.4 versus 10.2±6.1 days, p=0.004) and a trend toward a lower incidence of lymphocysts (3% versus 14%, p=0.090) than women in the conventional lymphadenectomy group (n=74). The rates of recurrence-free survival (3-year: 87.6% vs. 82.9%) and overall survival (3-year: 100% vs. 91.0%) did not differ between the SLN group and the conventional lymphadenectomy group (p=0.846 and p=0.254, respectively).ConclusionSLN biopsy does not seem to be associated with an inferior survival outcome compared with conventional lymphadenectomy in women with early primary cervical cancer. In addition, it is associated with less blood loss and a shorter length of hospital stay.Copyright © 2024, the Chinese Medical Association.
