Cancer brachytherapy is a form of radiation therapy used in the treatment of cancer.

During brachytherapy, radioactive seeds or sources are inserted into the tumor or into the body cavity close to the tumor.

These sources emit radiation, which damages the DNA of cancer cells, preventing them from growing and dividing.

The radiation is delivered locally, allowing for precise targeting of the tumor while minimizing damage to surrounding healthy tissues.

Brachytherapy can be used to treat various types of cancer, including prostate cancer, cervical cancer, breast cancer, and skin cancer, among others.

It may be used alone or in combination with other treatments such as surgery, chemotherapy, or external beam radiation therapy, depending on the specific characteristics of the cancer and the individual patient.

Here are some common types as below:

  • Interstitial Brachytherapy
  • Intracavitary Brachytherapy
  • Intraluminal Brachytherapy
  • Surface Brachytherapy
  • High-Dose Rate (HDR) Brachytherapy
  • Low-Dose Rate (LDR) Brachytherapy

Following are the procedure steps:

Patient Evaluation:

  • The process begins with a thorough evaluation of the patient's medical history, physical examination, and diagnostic imaging (such as CT scans, MRI, or PET scans).
  • The oncology team will assess the type, stage, and location of the cancer to determine if brachytherapy is an appropriate treatment option.

    • Treatment Planning:

    • Once the decision is made to proceed with brachytherapy, the patient undergoes treatment planning.
    • This involves imaging studies to precisely locate the tumor and surrounding healthy tissues.
    • Sophisticated computer software is used to develop a customized treatment plan that optimizes radiation delivery to the tumor while minimizing exposure to nearby organs and tissues.

      • Implantation of Radioactive Sources:

      • Depending on the type of brachytherapy and the location of the tumor, the procedure may be performed in an operating room, radiation oncology suite, or specialized brachytherapy facility.
  • During the procedure, the patient may receive anesthesia or sedation to ensure comfort.
  • For interstitial brachytherapy, needles, catheters, or applicators are inserted into the tumor or surrounding tissue under imaging guidance.
  • For intracavitary or intraluminal brachytherapy, specialized applicators or catheters are inserted into the body cavity close to the tumor.
  • Radioactive sources, either temporarily or permanently, are placed into the implanted devices or applicators according to the treatment plan.
  • The sources emit radiation, delivering the prescribed dose directly to the tumor.

    • Monitoring and Follow-Up:

    • After the radioactive sources are implanted, the patient is closely monitored to ensure proper positioning and radiation delivery.
    • Depending on the type of brachytherapy, the duration of treatment may vary from minutes (for high-dose rate brachytherapy) to days or weeks (for low-dose rate brachytherapy).
    • During the treatment period, patients may stay in the hospital or receive outpatient care, depending on the specific circumstances.
    • Following the completion of treatment, patients undergo regular follow-up appointments with their oncology team to monitor their progress, manage side effects, and assess treatment response.
