Image fusion prostate biopsy

El prostate cancer It is the most common cancer in men and in most cases presents no symptoms until it is in very advanced stages, which is why early diagnosis is vital for its cure. Therefore, always striving for excellence,  ICUA at its facilities of the Clínica CEMTRO offers its patients a novel and revolutionary technique  for the diagnosis of prostate cancer, in order to offer its patients the best medical care and services.

This pioneering transperineal biopsy technique represents the latest in diagnostic imaging, combining 3-tesla magnetic resonance imaging with ultrasound. This fusion of diagnostic images increases the biopsy's accuracy, improving and refining tumor diagnosis. One of the challenges of early detection is distinguishing between cancers that may be problematic and those that will not. It has been shown that up to 40% of tumors detected and treated would never have caused the patient any problems had they been allowed to progress.

In addition, screening of prostate cancer This implies, If the results are abnormal, perform repeated biopsies, chemically castrate the patient, apply local radiotherapy, or remove the prostate, with the risk that these measures have of producing urinary incontinence, or impotence, or of generating a local infection or sepsis or other surgical complication that can be fatal.

Traditionally, when PSA (Prostate-Specific Antigen) levels were elevated in the blood or a digital rectal exam was suspicious, a transrectal prostate biopsy was performed to determine if prostate cancer was present, but this presented two major problems:

 Its low detection rate: If 5 out of 10 men who undergo a biopsy have a tumor, a transrectal biopsy only detects 2. Therefore, it was very common for patients experiencing progressive increases in PSA levels to have to undergo further biopsies. This system created a false sense of security in patients, delaying their diagnosis and reducing their chances of a cure.

– Risk of infections: When the biopsy is performed through the rectum, the biopsy needle could carry fecal bacteria to the prostate and trigger a prostate infection (prostatitis) or even other conditions. severe sepsis.

ADVANTAGES OF PROSTATE MAPPING

This diagnostic program is based on two technologies: the 3 Tesla Multiparametric Magnetic Resonance Imaging, which allows visualization of lesions suspicious for prostate cancer with high sensitivity and in a harmless manner (without radiation for the patient) and with a very high negative predictive value, which in many cases will allow avoiding an unnecessary biopsy; and the BIOPSEE image fusion system MRI-ECO that performs prostate mapping via transperineal route (through the skin and not through the rectum) on an outpatient basis, projecting the location of the tumor found in the MRI in three dimensions onto the three-dimensional ultrasound image, allowing the biopsy needle to be directed exactly to the site of the lesion.

The main advantages offered by this system are:

▪ Performing the biopsy transperineally (through the skin and not through the rectum) It reduces the rate of prostate infection or sepsis from 3% to 0,01%.

▪   If 5 out of 10 patients had a tumor, we would detect 4,5. which represents a detection rate more than double that of transrectal biopsy.

▪   Detects tumors previously located in the prostate (25% of tumors), very difficult to detect with transrectal biopsy.

▪ The patient also obtains the biopsy result the next dayThis reduces the stress associated with waiting for results, which is typically one week to 10 days.

▪ The improvement in diagnostic accuracy The information obtained by this program is fundamental, as it allows for a much more appropriate decision-making process regarding the treatment to follow, depending on the type of tumor the patient has.

▪   The probability of choosing the right treatment option for each patient is much higher.

This is a diagnostic strategy supported by multiple publications in scientific journals that is already being applied in leading centers of Germany, the United Kingdom and the USA
