Percutaneous interstitial brachytherapy for adrenal metastasis: technical report

Area of Science:

• Interventional Radiology
• Oncology
• Radiation Oncology

Background:

• Adrenal metastasis presents a significant clinical challenge.
• Existing treatments for adrenal metastasis may have limitations.

Observation:

• A novel interstitial brachytherapy technique was adapted from radiofrequency ablation.
• The procedure was performed on an outpatient basis under local anesthesia and CT guidance.
• Treatment plans prioritized tumor eradication while preserving adjacent organs.

Findings:

• Two patients with adrenal metastasis (uterine cervical cancer, malignant melanoma) were successfully treated.
• The procedure took 2.5 hours with no immediate or delayed complications.
• FDG PET-CT scans showed no uptake post-treatment, indicating tumor eradication.
• No adrenal tumor recurrence was observed for over six months in both cases.

Implications:

• This interventional brachytherapy shows promise as a safe and effective treatment for adrenal metastasis.
• Outpatient brachytherapy offers a potentially less invasive option for managing adrenal tumors.
• Further studies are warranted to confirm the long-term efficacy and applicability of this technique.
