Summary
SPECT-CT imaging improved sentinel lymph node detection in melanoma patients, identifying the node in 100% of cases. This technique offers clinically relevant findings, especially for melanoma on the trunk or head and neck.
Area of Science:
- Oncology
- Nuclear Medicine
- Diagnostic Imaging
Background:
- Prognosis of cutaneous melanoma is significantly impacted by lymph node metastasis.
- Sentinel lymph node biopsy (SLNB) is an innovative oncological approach.
- Accurate sentinel node identification is crucial for melanoma staging and treatment.
Purpose of the Study:
- To evaluate the contribution of SPECT-CT imaging in locating sentinel nodes for melanoma patients.
- To assess the added value of SPECT-CT compared to conventional imaging techniques.
Main Methods:
- A study involving 18 melanoma patients (10 female, 8 male) aged 14-83.
- Sentinel node search utilized dynamic scintigraphy, planar imaging, and SPECT-CT.
- Data collected from March 2007 to October 2008 at San Carlos University Hospital.
Main Results:
- Conventional imaging located sentinel nodes in 88.88% (16/18) of patients.
- SPECT-CT successfully identified sentinel nodes in 100% (18/18) of patients.
- Clinically relevant findings were detected by SPECT-CT in 33.33% (6/18) of cases.
Conclusions:
- SPECT-CT imaging provides crucial clinical information for sentinel node assessment in melanoma.
- The technique is particularly valuable for melanoma cases on the trunk and head/neck regions.
- SPECT-CT enhances the diagnostic accuracy of sentinel lymph node biopsy in melanoma management.
