Summary
Sentinel node (SN) biopsy accurately stages early oral cancer. This technique identifies micrometastases, potentially avoiding unnecessary neck dissections and their complications.
Area of Science:
- Oncology
- Surgical Oncology
- Head and Neck Cancer Research
Background:
- Accurate staging of oral cancer is crucial for effective treatment planning.
- Sentinel node biopsy (SNB) is an evolving technique for staging nodal metastasis.
- Identifying the sentinel node (SN) is key to SNB success.
Purpose of the Study:
- To evaluate the efficacy of sentinel node biopsy in staging early-stage oral cancer (T1-T2N0).
- To assess the combined use of lymphoscintigraphy, blue dye, and gamma-ray probe for SN identification.
Main Methods:
- Forty-one patients with T1-T2N0 oral cancer underwent lymphoscintigraphy and SN biopsy.
- SNs were identified using blue dye and a gamma-ray probe.
- Patients subsequently underwent modified radical neck dissection for comparison.
Main Results:
- Sentinel nodes were successfully identified in 39 out of 41 patients.
- SN biopsy correctly predicted the pathological status in 35 patients.
- Micrometastases were detected in the SNs of four patients, with no other positive nodes found.
Conclusions:
- Sentinel node biopsy is a valuable and accurate staging method for T1-T2 oral cancer with clinically negative necks.
- This technique can help avoid unnecessary radical neck dissections, preserving function and reducing morbidity.
- The combined approach of lymphoscintigraphy, blue dye, and gamma-ray probe enhances SN identification efficacy.
