Tracking Recurrent Cancer | Ask a Prostate Expert, Mark Scholz, MD

Another type of prostate issue is chronic prostatitis, or chronic pelvic pain syndrome. This condition causes pain in the lower back and groin area, and may cause urinary retention. Symptoms include leaking and discomfort. In severe cases, a catheter may be required to relieve the symptoms. If the problem is unresponsive to other treatments, your doctor may suggest a surgical procedure. If these do not work, your symptoms could progress and become chronic.

An acute bacterial infection can cause a burning sensation. Inflammation of the prostate can affect the bladder and result in discomfort and other symptoms. This is the most common urinary tract problem in men under 50, and the third most common in men over 65. The symptoms of acute bacterial prostatitis are similar to those of CPPS. Patients may experience a fever or chills as a result of the infection.

Closer To The Holy Grail

Currently PSMA PET/CT is not intended to be a screening tool. It is for those who have been diagnosed with prostate cancer and who either have a higher chance of it spreading or who have a recurrence and a rising PSA level after initial treatment. It is for men with suspected metastatic disease in their pelvis — for instance, in their lymph nodes, or outside of their pelvis in more distant lymph nodes, bones, or organs.”

“Our goal is to identify these sites early and to improve cure rates even though theyve had a relapse, so being able to see the disease is important knowledge, said Dr. Armstrong. Dr. Wong agreed. This advancement is much closer to the holy grail of precision and personalized medicine and will have a big impact on patient decision making and treatment options.

Do Ct Pelvic Scans Detect Cancer

While pelvic CT scans can detect a variety of issues, they can be especially useful for detecting cancer. In particular, doctors can use this technology to look for tumors in this part of your body, but they can also use these scans to monitor the growth of tumors, to see how treatments are working, and to guide treatments.

Increased Hope For The Future

The advent of improved cancer scanning with Axumin increases hope that other new types of scanning breakthroughs will be coming in the near future. For example, other types of PET scans, one in particular called PSMA, targets a specific molecule that is commonly present on the surface of prostate cancer cells. The potential advantage of PSMA extends beyond its usefulness for imaging it has a potential therapeutic application as well. PSMA ligands can be linked to more powerful radioactive substances that are strong enough to kill the cancer cells.

The prostate cancer community eagerly waited for scans to identify prostate cancers location in the body with the type of accuracy that these PET scans can achieve. These scans represent a remarkable breakthrough. Now that the FDA has approved this technology, insurance companies start exploring ways to offer coverage. Medicare was the first insurance company to cover it.

Abstract: Prostate cancer is one of the most common cancers in men worldwide, and primary prostate cancer is typically treated with surgery, radiation, androgen deprivation, or a combination of these therapeutic modalities. Despite technical advances, approximately 30% of men will experience biochemical recurrent within 10 years of definitive treatment. Upon detection of a rise in serum prostate specific antigen , there is great need to accurately stage these patients to help guide further therapy. As a result, there are considerable efforts underway to establish the role of positron emission tomography in the diagnostic algorithm of biochemically recurrent prostate cancer. This manuscript provides an overview of PET tracers used for the detection and localization of prostate cancer in the setting of biochemical recurrence with a focus on PET tracers that are currently being used in clinical practice in the United States.

What You Need To Know About The Prostate Pet Scan For Prostate Cancer Recurrence

A enlarged prostate can also cause blockages in the urethra. A blocked urethra can also damage the kidneys. A patient suffering from an enlargement of the prostate may have pain in his lower abdomen and genitals. If pain is present, a digital rectal examination will reveal hard areas. A doctor may prescribe surgery or perform an endoscopic procedure. If the enlarged prostate is not completely removed, it will shrink.

While the size of an enlarged prostate will influence the extent of urinary symptoms, men may experience a range of urinary symptoms. Some men have minimal or no symptoms at all. Some men will have a very enlarged prostate, whereas others will have a mild enlargement. Generally, the symptoms can stabilize over time. Some men may have an enlarged prostate but not notice it. If they have an enlarged colon, their physician can perform a TURP procedure.

A Different Way To Detect Metastases

Most men diagnosed with prostate cancer have localized disease, meaning the cancer appears to be confined to the prostate gland. However, certain factors have been linked to a higher risk of the cancer eventually spreading .

Currently, in the United States and many other countries, most men diagnosed with high-risk localized prostate cancer undergo additional testing to see if there is evidence of metastatic cancer. For many years, that has been done with a conventional CT scan and a bone scan , the latter because prostate cancer often spreads to the bones.

But both imaging technologies have limitations. Neither is particularly good at finding individual prostate cancer cells, and thus can miss very small tumors. And bone scans can detect bone damage or abnormalities that were caused by something other than cancer , resulting in false-positive findings that can lead to unnecessary additional testing.

So, researchers have been developing and testing other imaging agents that can find prostate cancer cells specifically in the body, Dr. Shankar explained.

As their name implies, PET-CT scans combine a CT scan with a PET scan, another type of nuclear imaging test that requires patients to receive intravenous injections of a radioactive tracer that can be detected on the scan.

Redefining Prostate Cancer Recurrence With Psma Pet Imaging

The presence of metastatic prostate cancer, which was once determined based on conventional imaging, is now being challenged with the introduction of PSMA PET scans and earlier detection of metastatic disease that had previously been considered subclinical. In a sub-analysis of the OSPREY trial , 58% of patients were upstaged from M0 by conventional imaging to M1 by PSMA PETCT . As non-regional lymph nodes, bone or visceral metastases are revealed without conventional imaging correlates, it suggests metastatic disease based on imaging techniques exists on a continuum on which a patient transitions from BCR to metastatic disease . Risk stratifying BCR patients with terminology such as: BCR with negative conventional imaging and negative PSMA PETCT imaging, BCR with positive PSMA PETCT and negative conventional imaging, or BCR with positive PSMA PETCT and positive conventional imaging, will aid the clinician in counseling the patient and developing a therapeutic strategy. It remains unclear if non-specific abnormalities on CT will be overcalled given findings on PSMA PET imaging.

PSMA PET and Functional Imaging – 2021 Prostate Cancer Patient Conference

The conventional imaging methods typically used for prostate cancer patents, including CT, MRI, and bone scan, have limitations when it comes to disease detection, according to Steve Huang, MD, Nuclear Medicine Department, Cleveland Clinic.

Compared with other imaging options, PSMA PET scan has greater sensitivity and can detect metastases sooner, allowing clinicians to better serve patients and make treatment decisions earlier, he says. PSMA PET scan makes it possible to see a smaller volume of cells, which allows oncologists to localize the disease and determine the best approach to treatment.

PSMA, or prostate-specific membrane antigen, is a protein on the surface of many prostate cells and it has been shown that radiotracers tagged to PSMA can identify early, low-volume sites of lymph node or distant metastases of prostate cancer, explains Dr. Tendulkar.

The first PSMA-targeted PET imaging drug for prostate cancerGallium 68 PSMA-11 was approved by the FDA in 2020 for patients with suspected prostate cancer recurrence and metastasis. This approval was based on phase III clinical trials that demonstrated a significant increase in accuracy for the detection of prostate cancer compared with standard imaging modalities. In 2021, a second FDA approval followed for Pylarify for the same indication.

How Is Prostate Cancer Treated

There are many treatment options for cancer limited to the prostate gland. You and your doctor should carefully consider each option. Weigh the benefits and risk as they relate to the aggressiveness and/or stage of the cancer as well as your age, overall health, and personal preferences. Standard treatments include:

  • Surgery : The surgeon makes an incision in the lower abdomen or through the perineum and removes the prostate. If they cannot remove the entire tumor, you may need radiation therapy. You will need to keep a urinary catheter in place for several weeks after the procedure. Possible side effects can include incontinence and impotence. Some surgeons may use three small incisions to do robot-assisted prostatectomy. This may result in a shorter hospital stay and quicker recovery. This procedure may be preferable for some patients, but not for all.
  • External beam therapy : a method for delivering a beam of high-energy x-rays or proton beams to the location of the tumor. The radiation beam is generated outside the patient and is targeted at the tumor site. These radiation beams can destroy the cancer cells, and conformal treatment plans allow the surrounding normal tissues to be spared. See the External Beam Therapy page for more information.
  • Active surveillance: No treatment, with careful observation and medical monitoring.

Advanced treatment options may avoid or minimize some of the side effects associated with standard therapies. These options include:

What Is A Pet Scan And Why Is It Used For Prostate Cancer

New GE Discovery IQ PET Scanner

  • What is a PET scan? A PET Scan, short for Positron Emission Tomography Scan, is an imaging technique that uses radioactive tracers to clearly image targeted areas in the body. It is primarily used in the diagnosis, initial staging and treatment strategy, to assess the effectiveness of therapy and for restaging, or the evaluation for recurrent disease after treatment.
  • Why is a PET scan used for prostate cancer? PET scanning is used for prostate cancer because of its superior ability to target and capture images of prostate cancer on a cellular level. This allows for more accurate staging and restaging in the overall prostate cancer treatment strategy. With new radiotracers being developed and studied, PET scanning continues to lead the way in what will be possible for imaging during treatment of prostate cancer.

PET scanning has revolutionized the way prostate cancer is imaged because of its ability to target cancer on a cellular and molecular level. PET Scanning uses a radioactive tracer that is absorbed and visualized in cancerous cells related to the prostate. This makes a PET scan a better choice than more conventional imaging modalities that only evaluate an anatomical snapshot of abnormalities rather than the functional aspects of a PET scan.

Positron emission tomography/computed tomography is widely used in prostate cancer to evaluate the localized tumor burden and detect symptomatic metastatic lesions early. 18F-FDG is the most used tracer for oncologic imaging, but it has limitations in detecting early-stage prostate cancer. 68Ga-PSMA is a new tracer that has high specificity and sensibility in detecting local and metastatic tumors. But with the progression of prostate cancer, the enhancement of glucose metabolism in progressive prostate cancer provides a chance for 18F-FDG. This review focuses on PET/CT in the detection and prognosis of prostate cancer, summarizing the literature on 18F-FDG and 68Ga-PSMA in prostate cancer and highlighting that 18F-FDG has advantages in detecting local recurrence, visceral and lymph node metastases compared to 68Ga-PSMA in partial progressive prostate cancer and castration-resistant prostate cancer patients. We emphasize 18F-FDG PET/CT can compensate for the weakness of 68Ga-PSMA PET/CT in progressive prostate cancer.

PSMA PET scans are now FDA-approved and ongoing studies continue to suggest that it will be an even more valuable imaging tool used for both staging and restaging prostate cancer in the near future. The specifics of PSMA will hopefully allow for even more accurate imaging and the earliest possible detection when performing PET scans for prostate cancer.

When Is A PSMA PET Scan Used For Prostate Cancer?

Now FDA approved, we are currently performing PSMA PET Scans at our facility for the following purposes.

  • Staging: Patients with a first-time diagnosis of prostate cancer benefit from using a PSMA PET scan because of its superior ability to detect cancer spread offering the best possible future treatment options.
  • Restaging: Patients with suspected biochemically recurrent prostate cancer, meaning patients with elevated PSA levels after definitive therapy, benefit from using PSMA PET scans because of its ability to precisely locate recurrent prostate cancer and detect cancer spread. For both of these reasons, PSMA PET scans offer the best treatment options for recurrent prostate cancer.

Positron Emission Tomography Scan

A PET scan is similar to a bone scan, in that a slightly radioactive substance is injected into the blood, which can then be detected with a special camera. But PET scans use different tracers that collect mainly in cancer cells. The most common tracer for standard PET scans is FDG, which is a type of sugar. Unfortunately, this type of PET scan isnt very useful in finding prostate cancer cells in the body.

However, newer tracers, such as fluciclovine F18, sodium fluoride F18, and choline C11, have been found to be better at detecting prostate cancer cells.

Other newer tracers, such as Ga 68 PSMA-11 and 18F-DCFPyl , attach to prostate-specific membrane antigen , a protein that is often found in large amounts on prostate cancer cells. Tests using these types of tracers are sometimes referred to as PSMA PET scans.

These newer types of PET scans are most often used if its not clear if prostate cancer has spread. For example, one of these tests might be done if the results of a bone scan arent clear, or if a man has a rising PSA level after initial treatment but its not clear where the cancer is in the body.

The pictures from a PET scan arent as detailed as MRI or CT scan images, but they can often show areas of cancer anywhere in the body. Some machines can do a PET scan and either an MRI or a CT scan at the same time, which can give more detail about areas that show up on the PET scan.
