Recombinant TSH-stimulated, radioguided differentiated thyroid carcinoma surgery

Area of Science:

• Oncology
• Nuclear Medicine
• Surgical Oncology

Background:

• Differentiated thyroid carcinoma (DTC) can metastasize, posing treatment challenges.
• Locating occult metastatic foci in patients with negative diagnostic scans is difficult.
• Total thyroidectomy is a common treatment for DTC.

Observation:

• A 25-year-old female with DTC post-thyroidectomy had negative diagnostic iodine-131 (131I) body scans.
• A post-therapy 131I scan revealed metastatic foci.
• Radioguided surgery was performed without further hormonal manipulation.

Findings:

• Metastatic foci were successfully localized in the central neck compartment using radioguided surgery.
• Pathology confirmed 2 of 12 lymph nodes and a small focus in the fat were positive for metastasis.
• This represents a novel combination of provocative imaging, radioiodine therapy, and radioguided surgery.

Implications:

• This approach may offer a curative option for patients with image-negative metastatic DTC.
• Radioguided surgery can enhance the detection and resection of subtle metastatic disease.
• Further research is warranted to validate this combined strategy in a larger cohort.
