Surgical radiation therapy with vicryl-125I absorbable sutures

Area of Science:

• Oncology
• Medical Physics
• Surgical Technology

Background:

• Interstitial radiation therapy is a common cancer treatment.
• Current methods may involve lengthy procedures and significant radiation exposure.
• There is a need for more convenient and safer interstitial brachytherapy techniques.

Purpose of the Study:

• To evaluate the utility of absorbable Vicryl-125I sutures for interstitial radiation therapy.
• To assess the advantages of this method regarding patient and personnel safety and convenience.

Main Methods:

• Utilized absorbable Vicryl-125I sutures for interstitial implantation of Iodine-125 seeds.
• Employed minor surgical equipment for the implantation procedure.
• Calculated radiation dosage based on the properties of Iodine-125.

Main Results:

• Vicryl-125I sutures provide a long shelf life and a 60-day half-life for Iodine-125.
• Low energy (28 keV) allows patients to leave the hospital shortly after treatment.
• Seeds demonstrate good geometric and anatomic distribution, remaining in place post-implantation.
• Reduced radiation exposure for personnel due to low energy and quick implantation.
• No removal of sutures is necessary, further minimizing exposure time.

Conclusions:

• Absorbable Vicryl-125I sutures present a convenient, safe, and effective method for interstitial radiation therapy.
• This approach minimizes hospitalization and radiation exposure for both patients and medical staff.
• The technique simplifies implantation and dosage calculation, making it a practical option.
