Surgical Excision Can Spread Tumor Cells to Sentinel Node

Dr. Tvedskov pointed out that this difference did not achieve significance because of the small number of patients. There was no significant difference in the likelihood of micrometastases in nonsentinel lymph nodes between the two groups.

"This indicates that isolated tumor cells in patients with earlier surgical excision are not related to nonsentinel node metastases, and are therefore without clinical significance," she said.

The investigators reported that they have no relevant financial relationships.
