What Can Be Expected After Treatment Using Focal Therapy

MRI-Guided Focal Laser Ablation Therapy for Prostate Cancer

Patients treated with focal therapy still need to be actively monitored afterwards. This includes watching for disease that may have gone undetected, has returned, is spreading, or is appearing for the first time. If follow-up tests show that some of the treated cancer still remains, additional ablation, surgery, or radiation may be needed.

Prostate Cancer Patients Are Paying Hefty Price For Controversial New Treatment

Men hoping to avoid some side effects of prostate cancer treatment are shelling out tens of thousands of dollars for a procedure whose long-term effects are unknown and insurers, including Medicare, wont pay for.

Proponents say high-intensity focused ultrasound can have fewer negative side effects than surgery or radiation, while giving some patients another option between actively watching their cancer and those more aggressive steps. Critics, however, say the procedure is being oversold, leading some patients to get a treatment they dont need.

Device makers are busy selling the $500,000-and-up machines to doctors around the country and offering training courses. Billboards advertising this new non-invasive treatment for prostate cancer are springing up, while treatment center websites promise a safer method with benefits such as no erectile dysfunction and no incontinence, although studies show those side effects can occur, but less often than with other types of more aggressive treatments. The treatment can range in cost from $15,000 to $25,000.

HIFU is the latest treatment to prompt concerns over whether there should be limits such as requiring tracking of results placed on expensive new technology while additional data is gathered.

In the U.S., advisory committees to the Food and Drug Administration twice turned down applications from manufacturers to market HIFU devices as a treatment for prostate cancer, citing not enough long-term evidence.

What Is Focal Therapy For Localized Prostate Cancer

Focal therapy is a treatment for prostate cancer of low to intermediate aggressiveness that is completely contained within the prostate.

For many years there have been two main approaches to managing localized prostate cancer. The first is active surveillance or watchful waiting. In cases of older men or low-risk patients, regular medical tests are conducted to make sure the cancer isnt spreading. No other action is taken because the cancer is stable or growing so slowly it wont cause problems right away. If tests show the cancer is spreading, treatments can begin. Of those men assigned to active surveillance, about one-third will eventually need to have surgery or radiation.

The second approach to treating localized prostate cancer has been the use of radiation or surgery. This is effective for removing any tumors present but is typically associated with side effects in the urinary, sexual, and bowel function. Two common side effects include loss of control over urinary functions and erectile dysfunction

Who Are Good Candidates For Focal Therapy

When focal therapy for prostate cancer first began to be used in about 2007, it was only as an alternative to active surveillance in very low-risk patients. Since then, the use of focal therapy has expanded to include those with favorable intermediate risk disease . The best candidates have a prostate gland of about 40cc in size or a tumor in the lower half of a larger gland, a single visible tumor on MRI, and the absence of cancer elsewhere in the gland .

In each case, the doctor will consider the patients general health and mental outlook, the size and location of the tumors present, and their chances of spreading more. Use of tests such as MRI, ultrasound, and biopsy can help decide if a patient will benefit more from focal therapy or from traditional treatments.

Different Types Of Focal Therapy

Focal Laser Ablation of Prostate Cancer: Numerical Simulation of ...
  • HIFU : HIFU focuses the energy of sound waves to create heat and destroy cancer cells. Just like a magnifying glass concentrating sun rays to burn a hole in the paper. During the procedure, an ultrasound probe is inserted into the patients rectum while the patient is asleep from anesthesia. Guided by MRI and ultrasound 3D-images, the physician finds the tumor, plus the area to be treated, and delivers the energy aimed at the diseased tissue in the prostate gland. HIFU is a noninvasive precision treatment that spares healthy tissue and lowers the chances of negative side effects associated with radical prostate surgery or radiation, such as impotence, incontinence and bowel function disturbance. UChicago Medicine is the first medical center in the Midwest to offer and perform this procedure with the newest Focal One advanced robotic HIFU technology. This fills a significant treatment void for men with localized prostate cancer who find themselves in between active surveillance and whole gland treatments such as radiation or surgery. The treatment has been used for years in both Europe and Asia.

Urologists Ariel Shalhav, MD, and Scott Eggener, MD, answer questions about new treatment options for prostate cancer, including focal therapy and HIFU, as well as specialized care programs for men diagnosed with advanced prostate cancer or at high risk for the disease.

Focal Laser Ablation: The Casit Approach

Focal laser ablation achieves oncologic control by inducing hyperthermic conditions throughout the target lesion. Successful treatment requires accurate guidance of the laser fiber to the target lesion as well as real-time monitoring. Both of these tasks can be achieved with magnetic resonance imaging, however, this method is time consuming and expensive. We are developing an alternative approach in which ultrasound and interstitial probes are used for laser fiber guidance and treatment monitoring respectively .

This project is a multi-disciplinary effort involving urologists, radiologists, pathologists, engineers and industry collaborators. The video below outlines our journey which started with the development of targeted biopsy for prostate cancer diagnosis.

All study patients were treated between 2013 and 2017, with a median patient age of 64 years.

Pre-treatment biopsy Gleason scores were 3 + 3 = 6 in 30.8% of patients 3 + 4 = 7 in 46.7% of patients and 4 + 3 = 7 in 22.5% of patients.

Most of the men had a pre-treatment clinical stage of cT1c. Nearly all of them had either one or two tumor sites on their gland.

This is an admirable mix of patients, suggested Eggener. “I give Dr Walser credit that two thirds of the patients he has treated have Gleason score seven or higher cancers, because most clinicians would agree that it should not be used routinely on people with lower grade cancers,” he said

The median PSA level of patients prior to treatment was 6.05 ng/mL and decreased to 3.25 ng/mL at 12 months post-treatment .

Tumor diameter above the median was the lone statistically significant predictor for a post-treatment positive MRI and thus the need for biopsy and the possibility of a confirmed recurrence.

Walser said that the patients in this study were overall highly educated and affluent. They tended to be white-collar professionals such as engineers and doctors who search online for alternative treatments to prostatectomy. Other alternative treatments including high intensity ultrasound and microwave ablation also appeal to this type of patient, he said.

Currently, FLA is not reimbursed by insurance or Medicare. Walser’s patients come via his Internet marketing or are self-referred.

Mri For Recurrent Prostate Cancer

With the limitations of US and CT imaging, MRI has been shown to be quite useful in the detection and staging of recurrent prostate tumors.959697MRI provides superior soft-tissue contrast resolution, high spatial resolution, multiplanar imaging capabilities, and a large FOV. The use of integrated endorectal and pelvic phased-array coils or the state-of-the-art multichannel phased array coil has led to improved visualization of the prostatic fossa. Although PI-RADS version 2.1 interpretation and reporting methods do not apply to posttreatment prostate cancer imaging, the technical standards of a high-quality mpMRI of the prostate in pretreatment setting governed by PI-RADS can be employed for posttreatment evaluation. The characteristic mpMRI findings of locally recurrent tumor include a hyperenhancing soft-tissue nodule in the prostatectomy fossa, which also exhibits isointensity to muscle on T1WI, mild hyperintensity on T2WI, and restricted diffusion. The use of mpMRI for recurrent prostate cancer continues to evolve and has potential to evaluate both local recurrence and distant bony and nodal metastases.98Functional information from MR spectroscopic imaging and DWI may complement morphologic MRI by reflecting tissue biochemistry and Brownian motion of water molecules, respectively. These functional imaging techniques may be used to supplement conventional MR imaging in diagnostic clinical studies.

The Mri Focal Laser Ablation Procedure

The following illustrations show the steps involved in MRI Focal Laser Ablation:

  • Pre-procedure MRI confirms placement of applicator in the target tissue.
  • The thin laser fiber is then placed into the tumor through the rectum, under MRI guidance.The laser is activated to begin heating of the tumor. Using MR images and special software allows the physician to see the tissue heating during laser irradiation, and to control how much energy is delivered.
  • During the procedure the MRI is also used to monitor temperature-sensitive changes in the prostate tissue. This unique feature allows the physician to see the tissue heating while applying the laser energy. At the same time, the destruction of tissue and tumor is confirmed. Typically the laser procedure takes about 1 hour.
  • Results are confirmed with MR images. The laser applicator is removed. The entire procedure, including preparation time, lasts approximately 1.5 to 2 hours.

    Other Factors Affecting Prostate Cancer Treatment Cost

    Apart from the type of surgery or treatment and the choice of technology, the following are some of the factors that affect the overall prostate cancer treatment cost:

    Type of Hospital

    There are several hospitals around the world that provide world-class medical treatment to patients. The greater the number and quality of services offered by the hospital, the expensive is the treatment at the hospital.

    Therefore, the total cost of prostate cancer treatment that you have to pay actually depends on the level of services that you expect from the hospital. To be able to receive five-star services from the hospital, you must be willing to pay lavishly for it.

    Experience of the Surgeon

    Expertise and skills of the treating doctor matter a lot when it comes to successful treatment of any cancer type. It takes a lot of patience, courage, and knowledge to treat a cancer patient and this is the reason why the most experienced surgeons tend to charge a greater fee for their services.

    However, that does not mean that all the experienced and qualified surgeons charge fees that an average patient cannot afford. There are many highly educated and skilled doctors for prostate cancer treatment that offer their services with an equal compassion at a reasonable rate. Therefore, one must try to find a credible doctor with required credential who charges a fee that a patient can afford.

    What Is The Outlook For Patients Who Receive Focal Therapy

    Focal Therapy for Prostate Cancer | Prostate Cancer Staging Guide

    While the use of focal therapy for localized prostate cancer appears to be a promising development in a number of ways, it is still considered investigational and not yet part of standard therapy. There are a number of reasons for this, as follows:

    • The criteria for selecting ideal candidates havent been fully agreed on. This is an important question because mistakenly using focal therapy in place of a more traditional treatment could allow a cancer to go under-treated.
    • The criteria for defining an index lesion still need to be agreed on.
    • The idea that the index lesion determines how the cancer will develop hasnt yet been proven.
    • The factors that define treatment success or failure, and the triggers for re-treatment still need to be determined.
    • The long-term effectiveness of focal therapy is unknown.
    • It isnt clear that all side effects are eliminated by using focal therapy.
    • Focal therapy doesnt allow for firsthand pathologic and biologic study of cancerous tissue, as can be done when using surgical treatment.
    • Focal therapy sometimes leaves behind untreated cancer, which could possibly raise the risk of more serious problems in the future.
    • The overall cost to the healthcare system may be greater for focal therapy than for standard treatments.
