Radioactive Seed Localization for Non-Breast Tissue Excision.

Area of Science:

• Oncology
• Surgical Innovation
• Medical Imaging

Background:

• Lymph nodes are frequent sites for cancer recurrence.
• Distinguishing lymphatic tissue from surrounding tissues during surgery is challenging.
• Radioactive seed localization (RSL) is a technique used in breast surgery to tag tissue for intraoperative identification.

Purpose of the Study:

• To evaluate the efficacy and applicability of RSL in non-breast cancer surgeries.
• To assess the use of RSL for localizing and excising non-palpable lymph nodes and masses in diverse cancer types.

Main Methods:

• Retrospective case series of 42 non-breast cancer patients who underwent RSL.
• Analysis of pathology results to determine tissue findings (benign, malignant, other).
• Inclusion criteria focused on patients undergoing RSL for non-breast related indications.

Main Results:

• Pathology revealed benign findings in 47.62% of patients, toxoplasma in 2.38%, non-necrotizing granulomatous disease in 4.76%, and malignancy in 45.24%.
• Two patients had non-lymphatic tissue (abdominal wall, lumbar region) successfully localized and excised using RSL.
• The technique proved effective in identifying and removing non-palpable lesions.

Conclusions:

• Radioactive seed localization is a versatile and effective method for localizing and excising non-palpable lymph nodes and masses in non-breast cancer cases.
• RSL demonstrates broad utility beyond breast surgery, aiding in accurate tissue identification and removal.
• The study supports the expanded application of RSL in oncologic surgery for various cancer types.
