Background:
Sentinel lymph node (SLN) biopsy may identify patients who may need completion lymphadenectomy and adjuvant therapy.
Methods:
Univariate and multivariate analysis were conducted for SLN status in a prospective cohort of 1,041 patients. A biopsy was recommended for melanoma greater than or equal to 1 mm thick or greater than or equal to .75 mm with poor prognostic features.
Results:
For sentinel node status, mitotic rate is very significant in univariate analysis. In multivariate analysis, Breslow, lymphovascular invasion, and primary site were significant. Breslow thickness greater than or equal to 2 mm and SLN with macroscopic burden greater than or equal to 2 mm are the only statistically significant variables predicting the non-SLN status in multivariate analysis.
Conclusions:
The data confirm the importance of Breslow, lymphovascular invasion, and body site for SLN status. The cutoff of 2 mm for tumor load in SLN appears to be a simple technique to find the high-risk patients with further lymph node disease.
