Abstract

BackgroundSentinel lymph node (SLN) biopsy is a staging technique for occult lymph node disease. SLN biopsy has been applied to select patients with sarcoma, although the clinical utility remains uncertain.MethodsA PubMed/MEDLINE literature search was performed, and SLN biopsy outcomes were analyzed using a Bayesian meta-analytic approach to obtain point and interval estimates of rates of interest.ResultsSixteen studies involving SLN biopsy in patients with sarcoma were identified. Of 114 patients reported, 14 patients had positive SLNs (crude estimate, 12%; meta-analysis estimate, 17%). The meta-analysis false-negative rate was 29% (95% credible interval, 5%–59%). Recurrence and death rates in the SLN-positive group were higher than in the SLN-negative group.ConclusionsThis investigation highlights the current role of SLN biopsy in select patients with sarcoma for tumor staging. Questions regarding the high false-negative rate and management of micrometastatic lymphatic disease in patients with sarcoma still exist.
