ASO Author Reflections: The Clinical Relevance of Sentinel Nodes in Minor Lymph Node Fields Such as the Triangular Intermuscular Space in Patients with Melanoma

Summary: This study aimed to determine the clinical significance of sentinel nodes (SNs) in the triangular intermuscular space (TIS) in patients with melanoma. It found that 11% of patients with melanomas on their upper back had TIS SNs, and retrieval of these SNs was important for accurate staging and to minimize the risk of recurrence in the TIS.

Summary: This study confirms the increased accuracy of SPECT/CT for identifying SLN metastases, which appears to have a significant therapeutic benefit, although there is an increased risk of cancellation of the SNB procedure on the day of surgery.
