North Dallas Urologist Uses GPS to Deliver Prostate Cancer Radiation

Thursday, June 4th, 2009

With the help of sister company North Dallas Radiation Oncology Center, Dr. Mark Allen, MD of North Dallas Urology Associates brings a new technology to North Texas prostate cancer patients to help reduce the side effects of prostate cancer radiation therapy.  According to CBS 11 News Dallas, “North Dallas Radiation Oncology, in Plano, is one of the only Texas facilities using the Calypso 4D Localization System, otherwise known as GPS for the body.”  This technology allows the radiation to be directed specifically on the malignant tissue and prevents healthy tissue from accidental irradiation thus reducing long-term side effects.  For the entire article, video news coverage and patient testimonial, please visit the CBS News 11 website by clicking on the below link (be patient as the written article appears quickly but the video takes longer to download in the right margin).

New Machine Uses GPS To Deliver Cancer Radiation

Prostate Cancer Radiation Treatment | Organ Motion

Prostate motion documented in the daily report demonstrates motion of the prostate of greater than 1cm over 6 minutes.

Prostate motion documented in the daily report demonstrates motion of the prostate of greater than 1cm over 6 minutes.

If you are considering radiation treatment for your prostate cancer, it is important to know about organ motion.  Organ motion is prevalent, variable, and unpredictable during radiation therapy.  It presents challenges to delivering precise external beam radiation to the prostate.  A recent multi-institutional study showed that patients experienced organ motion during treatment fractions and the direction and degree of the motion is highly variable—from patient to patient and day to day.  The common methods used for target localization cannot provide continuous, real-time, objective guidance to clinicians managing patients receiving radiation therapy treatments.  The Calypso® 4D Localization System™ and Organ Motion is Prevalent, Variable, and Unpredictable implanted Beacon® electromagnetic transponders provide improvements with continuous, real-time tumor setup and monitoring without the use of additional ionizing radiation — GPS for the Body®.

Dr. Mark Allen of North Dallas Urology Associates is committed to providing leading edge treatment options to his patients and is pleased to offer the Calypso® 4D Localization System™ / GPS for the Body®.  Please visit click here to learn more information and schedule a consultation with Dr. Allen to see if you are a candidate for this highly effective prostate cancer radiation treatment.

Robotic Radical Prostatectomy | What To Expect

Monday, January 26th, 2009

If you are considering a da Vinci Prostatectomy to treat your prostate cancer, here is what you can expect from initial appointment to follow-up care.

1. Initial Appointment

Typically, your primary care physician will check your PSA levels in your blood workup during your routine check-up.  If your laboratory results show an “elevated PSA”, you will be referred to a urologist for further testing.

2. Laboratory Results

The exam likely consists of a standard digital rectal exam (DRE), in which Dr. Allen manually palpates the prostate by way of the rectum. Even if he detects nothing abnormal, he will schedule a biopsy to be certain there is no evidence of prostate cancer. The biopsy is performed by inserting a tubular structure in the rectum, from which projectile needles collect 5-6 “cores” of tissue from each side of the prostate. Although many patients tolerate the biopsy without medication, Dr. Allen may offer something to alleviate your discomfort and anxiety associated with the procedure.

3. Treatment Options

If you have an early diagnosis of prostate cancer, there is usually a range of treatment options. These may include conservative management, radiation therapy with external bream or brachytherapy, cryosurgery and prostatectomy – surgical removal of the prostate. The treatment options will depend on a number of factors, including the stage of the disease, and you age, health and personal preference.

If you choose to have a da Vinci® Prostatectomy – robotic prostate surgery – here is what you can expect:

4. Pre-Operative

You will have a physical examination and discuss the various types of anesthesia with your anesthesiologist. This visit is arranged by Dr. Allen and will likely occur the week before surgery. The evening before surgery, you will need to follow instructions for bowel preparation that Dr. Allen will provide.

5. Day of Surgery

Shortly before the operation, anesthesia is administered and you will sleep for the duration of the operation, which typically lasts 2-4 hours. The procedure begins when your abdomen is inflated with carbon dioxide gas, creating an operating space for the surgeon. Next, six small incisions, 1/4 to 1/2 inch in length, are made in your abdomen and ports are inserted to keep the incisions open.

During the procedure, Dr. Allen uses the da Vinci System’s laparoscopic surgical instruments and video camera, via the temporary ports, to direct the dissection of the prostate gland and adjacent tissue. If deemed appropriate, he tries to preserve the nerves attached to your prostate gland (nerve sparing). At the end of the surgery, the ports are removed from your abdomen and the remaining incisions are closed with sutures.

(For detailed information about this procedure, please set up a consultation with Dr. Allen.)

6. Post-Operative

After robotic prostatectomy surgery, you wake up very groggy and with a urinary catheter in place. You will likely spend one night in the hospital resting and recovering from the effects of the anesthesia. As the anesthesia wears off, there may be some discomfort, for which pain medication may be prescribed. During this time, the medical team gets you patient sitting, standing and eventually walking around, which is recommended throughout the recovery period. Because a catheter typically remains in place for approximately 7 days, Dr. Allen will review guidelines for use that will ease discomfort and ensure proper function of the catheter during this time.

7. Recovery Period

The first week post-operatively will likely be spent resting; however, frequent walks are encouraged. Depending on the your individual recovery needs, regular activities may resume as soon as soon as a few days after surgery; straining and heavy lifting is discouraged for the first four weeks post-operatively. Approximately one week after surgery, a post-operative follow-up is scheduled, at which time your bladder function may be assessed. This is done by filling the bladder with saline via the catheter, removing the catheter and then allowing you to void naturally. Some incontinence after surgery is normal and is typically managed with medication until bladder control resumes. Erectile dysfunction may also be a side effect of surgery. Like incontinence, this side effect may be discussed with the Dr. Allen and managed with medication until it lessens or completely resolves over time.

8. Follow-Up Care

After this treatment for prostate cancer, Dr. Allen will want to watch you carefully, checking to see if your cancer recurs or spreads further. Typically, Dr. Allen will outline a follow-up plan with you that includes regular visits, PSA blood tests and digital rectal exams, which will likely begin within a few months of finishing treatment. PSA tests are usually recommended about every 6 months for the first 5 years after treatment, and at least yearly after that.

Surgical side effects cut with robotics

ATLANTA, Georgia (CNN, Aug. 5 2008) — As 3D images illuminate the viewfinder, a joystick delicately maneuvers a pair of robotic arms. It may sound like a video game, but Dr. Nikhil Shah is actually performing cancer surgery.

In this case, the surgeon is removing a man’s prostate gland. Robotic surgery is a growing trend in treating prostate cancer. The number of cases have increased sevenfold in the past four years, from 10,000 in 2004 to a projected 70,000 in 2008, according to Intuitive Surgical Inc., the creators of the robotic device. The advantages of robotics — fewer side effects and quicker recovery times in many patients — have led to increased use for other surgeries, including hysterectomy, kidney cancer and some heart procedures.

“At first, men think we hook up a robot and then go get some coffee, but the reality is the robot arms are a tool that I control, just like a scalpel, ” said Shah, who has performed more than 600 robotic prostatectomies at St. Joseph Hospital in Atlanta, Georgia. . .
