Screening and Treatment Options for Prostate Cancer


According to the American Cancer Society, about 1 out of 7 men will be diagnosed with prostate cancer during his lifetime. Prostate cancer remains the most common cancer diagnosed in men, and the second most common cause of cancer death in men. There has been a good deal of controversy lately about screening for prostate cancer, specifically related to prostate specific antigen, or PSA. Most of the controversy arises from two trends which have recently been recognized: (1) a rise in the incidence of complications related to prostate biopsy and (2) the overtreatment of indolent, non-aggressive prostate cancers. Because of these trends, some providers believe there is no benefit to screening for prostate cancer.

However, research shows that since the advent of PSA screening in the late 1980’s, the mortality rate from prostate cancer has decreased by nearly 50%. In addition, the proportion of prostate cancer cases which were metastatic (spread outside the prostate) at the time of diagnosis has decreased dramatically since PSA screening has been available. For this reason, the American Urologic Association recommends PSA testing every 1-2 years in all men between the ages of 55 and 69. Most providers will also check PSA earlier in men with a family history and in African Americans, both populations who are at increased risk of prostate cancer.

If a true PSA elevation is found, the next step is usually a prostate biopsy. This test is typically performed in the office under local anesthesia (numbing medication), using an ultrasound (sonogram) probe through the rectum. The tissue samples taken are then examined by a pathologist under a microscope. In 5-7 days the diagnosis can be made and the urologist will be able to discuss the results.

If prostate cancer is diagnosed, the treatment options will depend upon the risk category (low, intermediate, high) and whether the cancer is contained within the prostate (localized) or not. Most patients have the option to undergo surgery or radiation, both of which have experienced recent technologic advancements. The robot-assisted radical nerve-sparing prostatectomy is the most cutting edge approach to surgical removal of the prostate. This procedure uses the da Vinci surgical system, which utilizes the latest in robotic technology to provide better visualization, smaller incisions, less blood loss, and a shorter recovery period. This approach has virtually eliminated certain complications, and facilitates better nerve-sparing, improving sexual function after surgery. This surgery option is considered for most young and healthy prostate cancer patients.

For patients considering radiation, the newest technique is Cyberknife. This form of radiation also uses robotic technology, this time to better delineate the structures around the prostate (bladder, rectum), which helps to cut back on radiation side effects. The main advantage of radiation treatment is that it avoids anesthesia and thus is accessible to older patients who may not be able to tolerate anesthesia. The biggest advantages of surgery are the ability to physically remove and analyze the cancer, the ability to remove lymph nodes, and the option to safely give radiation after surgery when necessary.

An important response to the concerns of overtreatment has been increased utilization of active surveillance for prostate cancer. Active surveillance, which has been rapidly growing in popularity over the last decade, consists of observing non-aggressive cancers rather than removing or radiating them. It is important to distinguish this approach from pure observation, in that active surveillance leaves open the door for definitive treatment with surgery or radiation, if that becomes necessary. There are multiple ways to implement active surveillance, but most will consist of PSA, rectal exam, and repeat biopsy at varying intervals.

There have been many new advances in prostate cancer diagnosis and management over the last several years. Prostate MRI has been perfected to the point that it is now considered an important tool in diagnosis and workup of prostate cancer. With the advent of a 3 Tesla (or 3T) machine, an improvement over the previous 1.5T, prostate cancer can now be visualized before the biopsy, for better accuracy and more meaningful diagnosis during biopsy. In addition, many surgeons will use MRI images to assist their surgical technique, allowing them to spare nerves when possible and take more tissue when required.

In addition to MRI, there are multiple new laboratory tests which can help predict prognosis and help select which treatments are likely to be most successful for patients. Some tests can extract DNA from blood or urine to determine a patient’s likelihood that a prostate biopsy will be positive. This can be helpful if the PSA is found to be elevated, but the patient does not want to rush into biopsy. Some tests will further analyze the tissue removed at biopsy, to help determine whether a patient will be best served by surgery, radiation, or just active surveillance.

While the diagnosis of prostate cancer can be a scary and solemn time in a man’s life, recent clinical and technologic advances have made this a promising era in treatment and diagnosis. With proper screening, selection, and treatment, we will hopefully welcome a time when prostate cancer is truly a thing of the past.
