A Comprehensive Guide to Brachytherapy Treatment

“Brachytherapy”, also called “Internal radiation therapy”, represents an advanced approach within the realm of radiation therapy, a cornerstone of cancer treatment. Unlike conventional external beam radiation therapy, which emanates radiation from a machine outside the body, brachytherapy involves placing radioactive particles or sources directly inside or adjacent to the tumor site.

By doing so, brachytherapy delivers a targeted, high dose of radiation precisely to the tumor, while minimizing exposure to surrounding healthy tissues. This focused delivery allows for the administration of high radiation doses to specific areas of the body, enhancing treatment efficacy.

This therapy finds application in the treatment of various cancers, including cervical, prostate, breast, skin, lung, head and neck, and gum cancer, among others. Particularly, it is a widely utilized procedure for prostate cancer treatment, offering an alternative to surgery for gum cancer patients who may be unfit or do not require surgical intervention. One of the notable advantages of brachytherapy lies in its efficiency, as treatment completion often requires fewer sessions compared to conventional radiotherapy techniques. Moreover, many patients undergo brachytherapy on an outpatient basis, further enhancing its accessibility and convenience. Overall, brachytherapy is well-tolerated by patients, with fewer side effects reported, making it a valuable therapeutic option in the fight against cancer.

Types of Brachytherapy

There are two types of brachytherapy treatment:

Temporary brachytherapy: In this method, highly radioactive particles are placed in a catheter or slender tube for a specific amount of time and then withdrawn. Temporary brachytherapy can be administered at either a low-dose rate (LDR) or a high-dose rate (HDR).

Permanent brachytherapy: In this method, a radioactive seed or pellet is implanted in or near the tumor and left there permanently. After several months, the radioactivity level of the implanted seed eventually diminishes to nothing.

Before undergoing brachytherapy, patients may experience various signs and symptoms related to their specific type of cancer. These symptoms can vary depending on the location and stage of the cancer. However, some common signs and symptoms that may prompt the consideration of brachytherapy include:

Presence of a tumor or abnormal growth
Changes in bowel or bladder habits
Abnormal bleeding
Difficulty swallowing or breathing
Skin changes
Unexplained weight loss or fatigue

Preparation for brachytherapy involves several diagnostic procedures, including:

Pre-treatment ultrasound,
MRI,
CT scans,
Blood tests,
An electrocardiogram (EKG), and chest X-rays.

In addition, Bowel preparation may be necessary. Your physician will provide specific instructions tailored to your individual needs to ensure optimal readiness for the brachytherapy procedure.

Following brachytherapy, Doctors may advise follow-up scans or Physical examination to assess the effectiveness of the treatment and it is crucial to evaluate and determine whether the therapy has achieved its outcome.

patients might experience some side effects such as fatigue, discomfort, and urinary or bowel changes, which may subside within a few weeks. It's common for individuals to resume their normal activities gradually, although strenuous activities may need to be avoided for a short period. Patients are closely monitored by healthcare professionals to manage any side effects and ensure a smooth recovery process. In the long term, regular follow-up appointments and monitoring are essential to assess treatment efficacy and address any lingering side effects or concerns.
