Your Isotope Choice Makes a Difference

Not all brachytherapy radioisotopes are the same. Compared to alternative brachytherapy seeds, Cesium-131 offers the highest energy and shortest half-life.

Paladium-103

Introduced 2004

17 Day Half Life (18)

20.8 Kev

58 Days for 90% Dose

Detectable in the body for 170 Days

Cesium-131

Introduced 2004

9.7 Day Half-Life

The amount of time for the radiation to half. A shorter half life means quicker to PSA baseline. (8, 12, 13)

30.4 Kev

The energy levelย of the isotope. Higher energy leads to greater coverage of the infected organ.

33 Days for 90% Dose

Faster dose delivery rate.

Detectable in the body
for 97 Days

Iodine-125

Introduced 1965

60 Day Half Life (18)

28.5 Kev

204ย Days for 90% Dose

Detectable in the body for 600ย Days

For my patients, I use Cesium-131 instead of Iodine because most of the effective isotope life is spent in 4-5 wks, compared to the 60-day half-life of Iodine,โ€ he said. โ€œIodine will still be putting out a pretty good dose of radiation 8 or 9 months later. My patients have a shorter duration of acute uropathic complaints because of that.

  2. Cesium-131 Instructions for Use
  1. Cesium-131 brachytherapy seeds are indicated for the treatment of malignant disease (e.g., head and neck, eye, brain, breast, prostate, etc.) and may be used in surface, interstitial, and intracavitary applications for tumors with known radiosensitivity. The seeds may be used as a primary treatment or in conjunction with other treatment modalities, such as external beam radiation therapy, chemotherapy or as treatment for residual disease after excision of primary tumors. Contraindications: As with other brachytherapy sources, treatment of tumors in generally poor condition (e.g., ulcerated) is not recommended with Cesium-131 brachytherapy seeds due to the potential for source migration. Prior to use, please reference the Cesium-131 Instructions for more information on indications, contraindications, warnings, all precautions, and adverse events.

    Caution: Federal law restricts this device to sale by or on the order of a physician.
