Official Description

Brachytherapy isodose plan; simple (calculation made from single plane, 1 to 4 sources/ribbon application, remote afterloading brachytherapy, 1 to 8 sources)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Brachytherapy isodose planning is a specialized procedure used in the treatment of cancer, where radioactive material is strategically placed within or near a tumor to deliver targeted radiation therapy. This method allows for a concentrated dose of radiation to be administered directly to the cancerous tissue while minimizing exposure to surrounding healthy tissues. The term "isodose plan" refers to the calculation and mapping of radiation dose distribution within the treatment area, ensuring that the intended dose reaches the tumor effectively. In this specific procedure, the planning is categorized as "simple," which indicates that the calculations are made from a single plane and involve a limited number of sources. The procedure can utilize one to four sources or a ribbon application, and it is applicable in remote afterloading brachytherapy techniques, where the radioactive sources are loaded into the applicator after it has been placed in the patient. This approach can involve between one to eight sources, allowing for flexibility in treatment planning based on the individual patient's needs and the characteristics of the tumor being treated.

1. Indications

The brachytherapy isodose plan (CPT® Code 77326) is indicated for patients undergoing treatment for various types of cancer where localized radiation therapy is beneficial. The following conditions may warrant the use of this procedure:

  • Cancer Treatment The procedure is primarily indicated for patients diagnosed with cancer, where the goal is to deliver targeted radiation therapy directly to the tumor site.
  • Localized Tumors It is particularly suitable for tumors that are localized and can be effectively treated with brachytherapy, allowing for high doses of radiation to be administered with precision.
  • Remote Afterloading Brachytherapy This technique is indicated when remote afterloading is employed, which enhances safety and precision in the delivery of radioactive sources.

2. Procedure

The procedure for creating a brachytherapy isodose plan involves several key steps that ensure accurate treatment delivery. Each step is crucial for the successful implementation of the brachytherapy technique.

  • Step 1: Patient Assessment The initial step involves a thorough assessment of the patient, including imaging studies to determine the size, location, and characteristics of the tumor. This information is essential for planning the treatment effectively.
  • Step 2: Selection of Sources Based on the assessment, the physician selects the appropriate radioactive sources for the treatment. The plan may involve one to four sources or a ribbon application, depending on the tumor's requirements and the desired dose distribution.
  • Step 3: Isodose Calculation The physician then performs isodose calculations from a single plane, which involves determining the distribution of radiation dose around the tumor. This calculation is critical to ensure that the tumor receives the intended dose while minimizing exposure to surrounding healthy tissues.
  • Step 4: Treatment Planning After the calculations are completed, the physician develops a comprehensive treatment plan that outlines the placement of the radioactive sources and the expected dose distribution. This plan is essential for guiding the actual treatment procedure.
  • Step 5: Documentation Finally, all aspects of the isodose plan, including calculations, source selection, and treatment planning, are documented thoroughly to ensure compliance and facilitate future reference.

3. Post-Procedure

Post-procedure care following the brachytherapy isodose plan involves monitoring the patient for any immediate side effects related to the treatment. Patients may require follow-up imaging to assess the effectiveness of the treatment and to monitor for any potential complications. Additionally, the healthcare team will provide instructions regarding any necessary precautions related to radiation safety, especially if the patient has received a high dose of radiation. Regular follow-up appointments will be scheduled to evaluate the patient's response to treatment and to make any necessary adjustments to the ongoing care plan.
