What is Brachytherapy: Purpose, Procedure, Results, Preparation & Costs in India

Cancer treatment is a journey, and navigating the options can feel overwhelming. At Ayu, we believe in empowering you with the knowledge you need to make informed decisions about your health. This guide focuses on brachytherapy, a type of internal radiation therapy, offering a clear understanding of the procedure, its benefits, and what to expect in the Indian context.

What is Brachytherapy? A Targeted Approach to Cancer Treatment

Brachytherapy, also known as internal radiation therapy, is a precise cancer treatment where radioactive sources are placed directly inside or near a tumor. Imagine tiny seeds, pellets, wires, or capsules, each containing radioactive material, being strategically positioned to target cancer cells with a high dose of radiation while sparing surrounding healthy tissues. This localized approach allows for effective tumor control with potentially fewer side effects compared to external beam radiation therapy (EBRT), where radiation is delivered from outside the body.

Why is Brachytherapy Performed? Targeting Cancer with Precision

Brachytherapy is a versatile treatment option used for a variety of cancers and even some non-cancerous conditions. Here's a closer look at why doctors might recommend it:

• Treating Various Cancers: Brachytherapy is effective in treating cancers of the cervix, prostate, breast, skin, lung, head and neck, and even gum cancer. Its localized approach makes it particularly suitable for tumors in these areas.
• Essential for Cervical Cancer: For women with locally advanced cervical cancer, brachytherapy is often a vital component of their treatment plan. It plays a crucial role in achieving optimal outcomes and improving survival rates.
• Combined Treatment Approach: Brachytherapy is often used in conjunction with other cancer treatments like surgery and EBRT. It can be used after surgery to eliminate any remaining cancer cells, or alongside EBRT to deliver a more comprehensive and targeted approach. This combined strategy maximizes the chances of successful cancer control.

Who Needs Brachytherapy? Determining if it's Right for You

Whether brachytherapy is the right treatment option for you depends on several factors, including the type, location, and stage of your cancer, as well as your overall health. Your doctor will carefully evaluate your individual situation to determine if brachytherapy is a suitable and effective treatment strategy.

Here are some general scenarios where brachytherapy might be considered:

• Localized Tumors: If your cancer is confined to a specific area and hasn't spread to distant organs, brachytherapy might be an excellent option.
• Combination Therapy: If you're already undergoing other cancer treatments, like surgery or EBRT, brachytherapy might be added to your treatment plan to enhance its effectiveness.
• Recurrent Cancer: In some cases, brachytherapy can be used to treat cancer that has returned after initial treatment.

Preparation for Brachytherapy: Your Guide to Getting Ready (with India-Specific Tips)

Preparing for brachytherapy involves several steps to ensure the procedure is safe and effective. Here's a breakdown of what you can expect, with some considerations specific to the Indian context:

1. Consultation with a Radiation Oncologist: This is the first and most crucial step. You'll meet with a radiation oncologist, a doctor specializing in treating cancer with radiation therapy. They will review your medical history, conduct a physical exam, and order necessary imaging tests, such as CT scans, MRIs, or X-rays, to understand your condition thoroughly. They will explain the brachytherapy procedure in detail and answer any questions you may have.

2. Medical History Review: Be prepared to provide your doctor with a complete medical history, including any past illnesses, surgeries, allergies, and medications you are currently taking. This information is essential for ensuring your safety during the procedure. Don't hesitate to bring your medical records from previous treatments or consultations.

3. Patient Counseling and Informed Consent: Your doctor will thoroughly explain the brachytherapy procedure, including its potential benefits and risks. It's essential to ask questions and express any concerns you may have. Before the procedure, you'll be asked to sign an informed consent form, indicating that you understand the procedure and its potential consequences. Take your time reading the consent form and ensure you are comfortable with the information.

4. Physical Preparation: Depending on the location of the tumor being treated, you may need to undergo specific physical preparations. For example, if you're undergoing brachytherapy for cervical cancer, you may need to prepare your skin and perineum through shaving and antiseptic vaginal douches. Bowel preparation may also be necessary to ensure the rectum and sigmoid colon are empty. Your doctor will provide detailed instructions on how to prepare.

   • India-Specific Tip: In India, it's common for patients to seek advice from their family physician (family doctor) before undergoing any medical procedure. Consider discussing the brachytherapy plan with your family physician to get their perspective and address any additional concerns.

5. Management of Co-morbidities: If you have any existing health conditions, such as diabetes or heart disease, your doctor will carefully manage them to minimize the risk of complications during and after the procedure.

6. Prevention of Venous Thromboembolism: In some cases, your doctor may prescribe low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH) to prevent postoperative venous thromboembolism (blood clots) in high-risk patients.

7. Fasting: You may be asked to fast for a few hours before the procedure, especially if you will be receiving anesthesia. Your doctor will provide specific instructions regarding fasting.

8. Arrange for Transportation and Support: Since you may be feeling tired or experiencing some discomfort after the procedure, it's important to arrange for transportation to and from the hospital. Having a family member or friend accompany you can provide emotional support and assistance.

   • India-Specific Tip: Consider the travel time to the hospital and plan accordingly, especially if you live in a congested city. Public transportation can be unreliable, so it's often best to arrange for a private car or taxi.

The Brachytherapy Procedure: A Step-by-Step Explanation

The brachytherapy procedure involves placing radioactive material directly inside or near the tumor. The specific steps involved will vary depending on the type of cancer being treated and the type of brachytherapy being used. Here's a general overview of what you can expect:

1. Anesthesia: Brachytherapy is typically performed under anesthesia, either general or spinal, to ensure your comfort and minimize movement during the procedure. The type of anesthesia used will depend on the location of the tumor and the type of brachytherapy being performed.

2. Placement of Applicators: The first step is to place applicators, which are hollow tubes or needles, into or near the tumor. The placement of these applicators is guided by imaging techniques, such as CT scans, MRI, or X-rays, to ensure they are positioned accurately.

3. Types of Brachytherapy: There are different types of brachytherapy, each with its own unique characteristics:

   • Low-Dose Rate (LDR) Brachytherapy: In LDR brachytherapy, tiny radioactive sources, often called seeds, are placed inside or near the tumor and release radiation slowly over days or weeks. These seeds may be left permanently in the body, where they gradually become inactive over time. LDR brachytherapy is commonly used for prostate, gynecologic, and head and neck cancers.

   • High-Dose Rate (HDR) Brachytherapy: In HDR brachytherapy, a small, highly radioactive source is temporarily placed inside or near the tumor for a short period, ranging from a few seconds to 20 minutes. This is done through the previously placed tubes or applicators. After each treatment session, the radiation source is removed, and no radioactivity remains in the body. HDR brachytherapy is commonly used for cervical, breast, prostate, and lung cancers.

   • Pulsed-Dose Rate (PDR) Brachytherapy: PDR brachytherapy involves delivering short pulses of radiation, typically once an hour, to simulate the overall rate and effectiveness of LDR treatment.

4. Image Guidance: Imaging techniques, such as orthogonal radiographs, CT scans, or MRI, are used for treatment planning and to guide the placement of applicators. MRI-based brachytherapy is considered the preferred method when available, as it can improve outcomes.

5. Radiation Delivery: Once the applicators are in place and the treatment plan is finalized, the radioactive source is delivered to the tumor. The duration of the radiation delivery will depend on the type of brachytherapy being used and the prescribed dose.

6. Applicator Removal (for HDR and PDR): After the radiation delivery is complete, the applicators are removed. There is no radioactivity remaining in the body after the applicators are removed.

7. Recovery: After the procedure, you will be monitored for any complications. You may experience some discomfort or pain at the treatment site, which can be managed with pain medication. The length of your recovery will depend on the type of brachytherapy you received and the location of the tumor.
