IMRT Treatment Process

We want you to be as knowledgeable about the process as possible, so we’ve outlined the typical treatment process.  If you have any questions or would like more information, we encourage you to call us to schedule a consultation.

Consultation
At your first visit, you’ll meet with radiation oncologist, Dr. Michael Selva, who will review your medical history and pathology reports, conduct a physical exam and take plenty of time (usually an hour and a half) to answer your questions. If you are ready to move forward with treatment, our team will help you set an appointment for positioning.

Positioning
At this appointment, your medical team will determine the exact position you should be in for treatment. To help you maintain your position during all of your visits, we’ll create a custom mold of your body that you’ll rest in each time you receive treatment. (A prostate cancer patient, for instance, will have a molded “pillow” that holds his torso in the proper position.) In addition to using the mold, your position will be meticulously documented with lasers.

Once your treatment position has been established, the medical team will conduct a CT scan to gather data needed to create your personal treatment plan.

Positioning typically only takes an hour to complete.

Treatment Planning
Using the information from the positioning and imaging sessions, the radiation oncologist, medical physicist, and dosimetrist (a person specially trained to calculate and plan radiation doses) work together to design the best IMRT treatment plan you. This process usually takes 3 days.

Plan Verification
Once your custom treatment plan is ready, the physicist performs a simulation treatment on a “phantom patient.” After that, you’ll return for a final planning appointment. Your medical team will use imaging technology to verify that the treatment plan they’ve created matches your anatomy and fine tune your position if necessary.

Treatment Delivery
Treatment can start as soon as your plan is finalized. Our team will work with you to select a regular treatment time the fits your schedule. Treatment visits usually take a total of 30 minutes; most of this time is used for undressing, dressing and positioning.

The actual delivery of radiation lasts only a moment or two. The number of treatment sessions required varies based on the type of cancer you have and the schedule your medical team recommends.

For prostate cancer patients, treatments are usually given once a day, 5 days a week for 9 weeks for a total of 45 treatments.

Monitoring & Follow-Up Care
Once a week, you’ll meet with your nurse and Dr. Selva. They’ll monitor your weight, vital signs and symptoms, guiding you through any difficulties you may encounter. At the conclusion of your treatments, you’ll meet with Dr. Selva to review the treatment’s effectiveness and discuss your long-term prognosis. After these visits, patients usually return to their referring physician for routine cancer monitoring.

What is IMRT?

IMRT (Intensity Modulated Radiation Therapy) is the most precise method of external beam radiation therapy currently available. It has been studied extensively and is the standard of care for many types of cancers.

IMRT uses a computer-controlled radiation delivery machine called a linear accelerator to deliver precise radiation doses to the tumor. The technology allows your medial team to create a treatment plan that delivers different levels of radiation doses to different parts of the treatment area (thus, it’s intensity modulated). This approach minimizes damage to healthy tissue that surrounds the tumor without compromising the therapy delivered to the tumor.

What is IGRT?

IGRT (Image Guided Radiation Therapy) is an enhancement to IMRT that uses real-time technology to detect movements of your organs during treatment. The information is fed back to the computer-controlled linear accelerator, which makes corresponding adjustments to track the radiation’s delivery with the movement of your organs, allowing you continue receiving a precise dose of radiation to the tumor while avoiding radiating healthy tissue. At our center, all IMRT treatments incorporate the use of the IGRT technology.

Frequently Asked Questions


What are your hours of operation?
Our business hours are Monday – Friday, 8 am – 5 pm; however, when the number of patients needing treatment is high, we sometimes operate from 6:30 am – 6 pm.

Can I work during treatment?
Many patients work while receiving treatments. You can expect to have some fatigue, ranging from mild to severe, during treatment. We encourage you to maintain the work and activity schedule that’s comfortable for you.

Can I choose my treatment time?
Yes, we’re happy to set daily treatment times that fit your work or personal schedule. Plan for treatments to take 30 minutes, door to door.

What types of cancer do you treat?
We treat all types of cancers for which radiation therapy is a recommended treatment option. This includes prostate cancer, breast cancer, gynecological cancers, head/neck cancers, lung cancer, bone cancer, rectal cancer and several others.

What type of treatment technology do you use?
We have two treatment vaults equipped to deliver IMRT (Intensity Modulated Radiation Therapy) and IGRT (Image Guided Radiation Therapy), both which are types of external beam radiation therapy that offer highly accurate tumor targeting.

In addition, we provide Radium-223-Chloride (Xofigo) therapy, a form of treatment that works by injecting radioactive isotope intravenously, and Quadramet, a treatment for pain associated with bone cancer.

How can I get a second opinion from your center?
Whether you’ve been presented with multiple treatment options (such as surgery or radiation therapy) or you’re choosing from among a few radiation oncologists or cancer centers, a second opinion can empower you with the confidence you need. Dr. Selva can review your medical records and meet with you to provide a second opinion on your case. To schedule a second opinion appointment, ask your primary physician to refer you to Dr. Michael Selva, or call us directly and we’ll initiate the process. Rest assured, when you are confronting cancer, most doctors understand and appreciate you taking a proactive role in your treatment by investigating all of your options.

How is your center affiliated with Urology San Antonio?
The Reyna Cancer Center is owned and operated by Urology San Antonio. Patients from inside and outside of the urology practice receive treatment at the center.
