Summary
Lymph scintigraphy and tumor scintigraphy aid in diagnosing head and neck cancers. Combined imaging improves localization accuracy and therapy planning for ENT malignancies.
Area of Science:
- Nuclear Medicine
- Oncology
- Head and Neck Surgery
Background:
- Head and neck cancers present diagnostic challenges.
- Accurate staging and localization are crucial for effective treatment planning.
Purpose of the Study:
- To evaluate the utility of lymph scintigraphy and tumor scintigraphy in patients with head and neck malignancies.
- To assess the combined diagnostic value of these imaging modalities.
Main Methods:
- 46 patients with head and neck tumors underwent lymph scintigraphy using 198Au colloid and tumor scintigraphy using 67Ga citrate.
- Procedures were performed individually and in combination.
Main Results:
- Lymph scintigraphy assessed cervical lymph system function and state, aiding in diagnosis and surgical treatment evaluation.
- 67Ga citrate scintigraphy confirmed tumor visualization, with higher uptake in lymphomas than carcinomas; a minimum tumor size of 1.5 cm was required.
- Tumor scintigraphy proved valuable for differential diagnosis, staging, and therapy monitoring, including early detection of residual disease and recurrence.
Conclusions:
- Both lymph and tumor scintigraphy expand diagnostic capabilities for head and neck tumors.
- Combined application offers advantages for precise localization and improved patient management.
