4D Brachytherapy for Prostate Cancer

What is 4D Brachytherapy?

4D Brachytherapy represents the latest advancement in prostate cancer treatment. This innovative technique is performed in a single session, allowing patients to receive a complete and effective treatment in one procedure.

One of the most significant differences of 4D Brachytherapy is its real-time control over the placement of “seeds” (tiny radioactive implants that deliver radiation directly to the tumor) with even greater precision. This exceptional accuracy is achieved by combining ultrasound and MRI (Magnetic Resonance Imaging) data, which are processed through specialized software and adjusted during the procedure.

In addition to enhancing treatment effectiveness, this approach further reduces the already low side effects associated with conventional brachytherapy. The procedure duration is also significantly shorter, approximately 45 minutes, which means less anesthesia time and faster recovery.

What Does the 4D Brachytherapy Procedure Involve?

4D Brachytherapy is an advanced and highly precise treatment for prostate cancer. At the Prostate Institute, the procedure follows a structured sequence to ensure maximum efficacy and safety.

Before 4D Brachytherapy

Before treatment, the focus is on thoroughly understanding the characteristics of the tumor and the prostate, including its size and shape, to guarantee the highest level of precision in planning. It is also essential to provide patients with clear information so that they are fully prepared for the procedure.

In the first phase, detailed imaging tests such as ultrasound and Magnetic Resonance Imaging (MRI) are performed to map the prostate and the tumor, defining their volume and morphology. This information is crucial for designing a treatment plan that is specifically adapted to each patient's needs.

An innovative software system is used to calculate with high precision the exact number of radioactive seeds required and their precise positioning. This detailed planning ensures that the radiation is directed at the tumor while reducing exposure to the surrounding healthy tissues.

Before the intervention, all necessary tests are carried out to ensure that everything is ready and that the patient feels safe and well-informed. This is the appropriate time to clarify any doubts about the procedure and to discuss additional concerns, such as dietary recommendations, preparation for the days leading up to the treatment, and expectations regarding the post-procedure recovery process.

During and After 4D Brachytherapy

The procedure lasts approximately 45 minutes and is performed under anesthesia, ensuring that the patient experiences no discomfort. During this time, radioactive seeds are implanted into the prostate using real-time imaging technology, guaranteeing absolute precision.

Thanks to the advanced technology used in 4D Brachytherapy, it is possible, during the procedure, to adjust the planned seed placement using MRI and ultrasound, if necessary, to ensure that radiation is delivered exactly where it is needed.

At the end of the procedure, a final confirmation is performed to ensure that everything is as planned, guaranteeing the maximum effectiveness of the treatment, which is completed in a single session.

4D Brachytherapy is a minimally invasive treatment, meaning that the patient can return home the same day or the following day, with simple instructions and care recommendations for the first few days of recovery.

After the treatment, follow-up consultations are scheduled with the physician to monitor the results and address any concerns the patient may have.

These consultations are essential for supporting patients in managing any potential symptoms, alleviating fears, providing reassurance, and ensuring their overall well-being.

What Is the Post-Treatment Process for 4D Brachytherapy?

The post-treatment phase of 4D Brachytherapy is characterized by rapid recovery and minimal side effects. However, some temporary effects may occur, including:

Urgency to urinate;
Increased urinary frequency;
Burning sensation or discomfort during urination.

These symptoms are generally acute manifestations and tend to resolve within a short period.

Studies show that after treatment:

Less than 1% of patients develop stress urinary incontinence;
Approximately 83-90% retain erectile function, a significantly higher rate compared to other treatments.

The medical team at the Prostate Institute ensures close follow-up after the procedure, providing comprehensive support to make patients feel comfortable and well-assisted throughout every stage of their recovery.
