Cryoablation for Recurrent Prostate Cancer
Prostate and Prostate Cancer
The prostate gland is an organ found only in men, located beneath the bladder.
Prostate cancer is a condition in which malignant cells originate from the tissues of the prostate, proliferating irregularly and excessively, leading to an increase in the size of the cellular components of the prostate gland.
Prostate cancer is the second most common cancer in men after lung cancer. It can exhibit slow growth, with a prolonged period before clinical symptoms appear. In other cases, the tumor may grow rapidly, allowing it to invade other tissues. In such instances, the time between the onset of the disease and its progression is very short.
Symptoms and Signs of Prostate Cancer
Prostate cancer often presents with symptoms related to urinary issues or abdominal pain. These symptoms can overlap with those of common conditions such as infections or benign prostatic hyperplasia.
Warning Signs:
Frequent urination
Weak urine flow
Inability to urinate
Urinary incontinence
Intermittent and weak urine flow
Presence of blood in urine
Prostate Cancer Treatment Methods:
Prostate cancer treatment involves various methods, and the most suitable option is chosen based on the patient’s condition and the progression of the cancer.
Surgery
– Hormone Therapy
– Radiation Therapy
Chemotherapy
– Cryotherapy
– Biological Treatment
Recurrence of Prostate Cancer
In cases where cancerous cells are not completely eradicated or destroyed during the initial treatment, conditions for the growth and proliferation of malignant cancer cells may arise. This does not necessarily mean that the treatment was incomplete or incorrect; rather, recurrence of malignancy is often common in the treatment of cancer. Cancer recurrence may manifest as secondary cancer (metastasis), where cancerous cells begin to grow and multiply in another organ of the body.
Intervention Clinics
The interventional clinics at pardis noor comprehensive imaging centers, utilizing advanced equipment and a specialized team, provide minimally invasive medical services with high precision and safety.
Treatment of Recurrent Cancer
In the treatment of cancer recurrence, the same previous methods are applied. However, a very new treatment has recently been introduced for patients experiencing recurrent prostate cancer.
Cryoablation is a technique for destroying cells through a cooling or freezing system. This method lowers the temperature of cancerous cells to a specific degree, causing the destruction of the cancer cells. This technique offers numerous advantages in the treatment of recurrent cancer.
Method of Performing the Procedure
Under the guidance of imaging equipment, a cryo needle is inserted into the tissue at the site of tumor recurrence. Once the needle is connected to the cryogenic generator, the tumor tissue is cooled to a temperature of -140 degrees Celsius. This significant drop in temperature leads to the destruction of cancer cells.
It is worth mentioning that this procedure does not require hospitalization or anesthesia and is performed on an outpatient basis. The procedure is generally painless and, in some cases, may involve very minimal discomfort.
Surgical Outcomes
Performing this procedure, whether as part of the initial treatment for cancer or in cases of cancer recurrence, can yield highly effective results in controlling and treating the disease. It is particularly recommended when the patient is not suitable for anesthesia or surgery.

Frequently Asked Questions
How is cryoablation performed in recurrent prostate cancer?
In this method, specialized needles are used to apply extreme cold to the cancerous tissue of the prostate, freezing and destroying tumor cells. This procedure is typically performed under imaging guidance.
Which patients are candidates for this method?
Cryoablation is primarily used for patients who have experienced a local recurrence of the disease following previous treatments such as surgery or radiotherapy, and where the lesion is confined to the prostate.
What is the advantage of this method compared to undergoing surgery again?
This technique is considered a minimally invasive method, offering a shorter recovery period and fewer complications compared to repeat surgery, while also providing localized disease control.
