Summary
Sentinel node biopsy accurately evaluates lymph node status in tongue carcinoma patients with clinically negative neck (cN0). Both lymphoscintigraphy and methylene blue dye mapping are effective, with combined methods offering the best detection.
Area of Science:
- Oncology
- Surgical Pathology
- Nuclear Medicine
Context:
- Accurate assessment of lymph node status in clinically negative neck (cN0) tongue carcinoma is challenging due to lack of reliable clinical and biochemical markers.
- Current treatment strategies for cN0 neck in tongue carcinoma involve some degree of uncertainty.
- Sentinel node biopsy offers a potential for personalized management of the cN0 neck in tongue carcinoma.
Purpose:
- To evaluate the accuracy of sentinel node biopsy in determining lymph node status for cN0 tongue carcinoma.
- To identify the optimal sentinel node localization technique for this patient group.
Summary:
- Sentinel nodes were successfully detected in all 24 tongue carcinoma cases using both lymphoscintigraphy and methylene blue dye mapping.
- Metastasis was confirmed in sentinel nodes of 4 cases; no non-sentinel nodes showed metastasis when sentinel nodes were negative.
- Detection rates were 3.5 nodes/case for lymphoscintigraphy, 2.7 for methylene blue dye, and 2.2 for combined methods.
Impact:
- Sentinel node biopsy provides an accurate method for assessing cervical lymph node status in cN0 tongue carcinoma.
- Both lymphoscintigraphy and methylene blue dye mapping are viable techniques, with their combination proving most efficient and practical for sentinel node detection.
