18 Oct Discover the Benefits and Applications of Brachytherapy in Cancer Treatment
The landscape of cancer treatment has been constantly evolving, with new techniques and technologies developed to enhance patient outcomes and minimize side effects. Among the many advances in radiation therapy, brachytherapy has emerged as an innovative and highly effective treatment option for various types of cancer.
In this educational blog, we will delve into brachytherapy: what it is, its benefits, and its applications in cancer treatment. Brachytherapy is a type of internal radiation therapy that involves placing radioactive material directly into or near a tumor. This approach enables the delivery of high doses of radiation to cancer cells while minimizing damage to surrounding healthy tissue, reducing side effects, and improving patient outcomes. Brachytherapy is utilized to treat various cancer types, including prostate, breast, cervical, and skin cancer, as well as certain gynecological and head and neck cancers.
In the upcoming sections, we will examine the two main types of brachytherapy—low-dose-rate (LDR) and high-dose-rate (HDR)—as well as the process, risks, and recovery associated with this advanced radiation therapy technique. Furthermore, real-world applications and case studies will illustrate the practical effectiveness of brachytherapy in cancer treatment and how it is fundamentally changing the face of radiation oncology at CenterPoint Radiation Oncology in Beverly Hills, CA.
1. Understanding Brachytherapy: Low-Dose-Rate and High-Dose-Rate
Brachytherapy is a specialized form of radiation therapy that involves placing radioactive sources close to or directly within a tumor. By providing a targeted and concentrated dose of radiation, brachytherapy minimizes the exposure of healthy surrounding tissue, resulting in fewer side effects and improved clinical outcomes. There are two main types of brachytherapy—low-dose-rate (LDR) and high-dose-rate (HDR):
a) Low-Dose-Rate (LDR) Brachytherapy: In LDR brachytherapy, small radioactive seeds or pellets are permanently implanted within or adjacent to the tumor site. These seeds release radiation gradually over weeks or months, slowly treating the tumor from the inside out. LDR brachytherapy is often used for prostate cancer, where it has been proven effective in ensuring local control and preserving the patient’s quality of life.
b) High-Dose-Rate (HDR) Brachytherapy: HDR brachytherapy involves temporarily placing a highly radioactive source within a tumor or a customized applicator for a few minutes per session. These sessions typically occur over several days or weeks, during which the patient receives multiple treatments. HDR brachytherapy is commonly used in the treatment of gynecological cancers, such as cervical and endometrial cancer, breast cancer, and certain head and neck cancers.
2. The Brachytherapy Process: Planning, Procedure, and Recovery
The brachytherapy process consists of three main phases – planning, procedure, and recovery:
a) Planning: The first stage in brachytherapy involves the development of a comprehensive treatment plan. This consists of imaging tests, such as CT scans, MRI, or ultrasound, to determine the exact location, size, and shape of the tumor. This information is used to design a customized treatment plan, which outlines the optimal placement, type, and dosage of the radioactive sources to be used.
b) Procedure: The brachytherapy procedure is typically performed by a radiation oncologist or a trained specialist, who places the radioactive material using specialized needles, catheters, or other devices. Depending on the type of brachytherapy (LDR or HDR) and the specific cancer being treated, the radioactive material may be implanted permanently or temporarily. The method of insertion and the duration of treatment can vary based on the patient’s individual needs and the tumor’s characteristics.
c) Recovery: While many patients can resume their daily activities shortly after treatment, some might experience mild discomfort or fatigue for a few days. In general, the side effects of brachytherapy are usually fewer and less severe than those experienced with external beam radiation therapy. Our medical team will closely monitor the patient’s progress and help manage any side effects or concerns that may arise.
3. Risks and Complications of Brachytherapy
As with any medical procedure, brachytherapy carries some potential risks and complications. These may include:
a) Infection: Although the risk is low, there is a possibility of infection at the site of the radiation source placement.
b) Tissue irritation: Temporary swelling, redness, or tenderness may develop around the treatment site, which typically subsides within a few days or weeks.
c) Urinary or bowel symptoms: In some cases, the treatment may cause temporary or long-term urinary or bowel symptoms, including pain, frequency, or urgency of urination; constipation; or diarrhea.
d) Radiation exposure: While brachytherapy has the advantage of limiting radiation exposure to healthy tissues, there is still a small risk of radiation-related side effects or long-term complications.
Our medical team will inform you about these risks and how to manage them, providing the necessary precautions and guidelines to ensure a safe and effective treatment.
4. The Role of Brachytherapy in Comprehensive Cancer Care
The integration of brachytherapy in cancer care offers numerous advantages for patients, including highly targeted treatment with fewer side effects and reduced exposure to healthy tissues. Brachytherapy may also be combined with other treatments, such as surgery, chemotherapy, or external radiation therapy, to enhance comprehensive cancer care and optimize patient outcomes.
In some cases, brachytherapy may also serve as an alternative treatment for those who may not be candidates for surgery or have contraindications to traditional radiation therapy. By providing flexible and personalized treatment options, brachytherapy widens the scope of patient care and reinforces the commitment of CenterPoint Radiation Oncology to meet the diverse needs of all cancer patients.
