RapidArc enables very fast therapy delivery, often in less than two minutes with just one revolution of the machine around the patient. It accomplishes this by shaping a highly focused treatment beam to target the tumor very precisely and to spare surrounding healthy tissue.
RapidArc (a form of volumetric modulated arc therapy (VMAT) implemented by Varian Medical Systems, Palo Alto, CA) and intensity modulated proton therapy (IMPT) are two most recent EBRT modalities that are used to treat prostate cancer. 1, 2 One of the

The radiation oncologist will thoroughly discuss side effects with patients prior to radiation therapy. If you have been diagnosed with prostate cancer, contact the Austin Center for Radiation Oncology to schedule a consultation with Dr. Richard Garza .
Radiation Therapy RapidArc®, the next technological advancement in radiation therapy, improves upon both IGRT and IMRT in that it delivers the same precise treatments in a shorter timeframe. This is possible because the technology delivers dose to the whole volume, rather than slice by slice.

16/6/2010· To report about initial clinical experience in radiation treatment of carcinoma of prostate with volumetric modulated arcs with the RapidArc (RA) technology. Forty-five patients with a median age of 72 ± 3, affected by prostate carcinoma (T1c: 22 patients, T2a-b: 17 patients, T3a-b: 6 patients. N0: 43 patients, N1-Nx: 2 patients, all M0), with initial PSA of 10.0 ± 3.0 ng/mL, were treated ...
9/9/2009· Biochemical failures (BF) of prostate cancer after external beam radiation therapy (RT) is not an unusual event and is observed in a substantial number of prostate cancer patients [1, 2]. CapSURE™ (Cancer of the Prostate Strategic Urologic Research Endeavor) data have demonstrated a biochemical failure rate following radiation therapy as high as 63% [ 3 ].

Prostate cancer is one of the most common cancers that affects men, with more than 240,000 cases diagnosed each year. Fortunately, it’s also very curable. In the past 25 years, the five-year survival rate for all stages has jumped from 69 percent to nearly 100
Since the prostate is one of the most common sites treated with IMRT, it’s no surprise that VMAT may soon supplant IMRT as a preferred method for delivering external-beam radiation therapy. A 2011 review of literature and clinical use found that several studies reported significant improvement in OAR (organs at risk) sparing with VMAT.
Once these values are determined, this study can act as a template to translate these measured errors to better understand the clinical impacts of the RapidArc errors for a prostate cancer group. It is likely that these results can be translated to other disease sites; however, another study …
The volumetric modulated arc therapy (VMAT) technique, in the form of RapidArc, is widely used to treat prostate cancer. The full-single arc (f-SA) technique in RapidArc planning for prostate cancer treatment provides efficient treatment, but it also delivers a higher radiation dose to the rectum.

The purpose of this study was to use various dosimetrical indices to determine the best intensitymodulated radiation therapy (IMRT) modality - for treating patients with prostate cancer. Ten patients with prostate cancer were included in this study. IMRT plans were designed to include different modalities, including the linac step and shoot, tomotherapy, RapidArc, and proton systems. Various ...
Since radiation therapy can encompass a larger area than surgery, more advanced or aggressive prostate cancers may be better conquered with radiation treatment for prostate cancer. Sometimes hormone therapy is used in conjunction with radiationin these cases to enhance the effect of the radiation.
RapidArc allows for a higher dose of radiation to be used to destroy cancer cells while sparing healthy tissue from damage. This technology is significantly faster than conventional radiation therapy and more targeted. Patients typically have fewer side effects from
RapidArc radiotherapy technology, produced by Varian Medical Systems, is an extremely fast and precise form of image-guided, intensity-modulated radiation therapy (IMRT). Image guidance improves tumor targeting. IMRT shapes the radiation dose so that it …
Martin O’Neill Cancer Center offers the most precise, leading-edge radiation delivery technologies available, including Volumetric Arc Therapy (VMAT) or RapidArc® Radiotherapy Technology. An advanced form of IMRT, VMAT/RapidArc delivers a precisely-sculpted three-dimensional radiation dose while the radiation source rotates around your body.
RapidArc technology, one of the latest innovations in radiation therapy for prostate cancer, is in use at Advanced Prostate Cancer Institute in Florida. The benefit of this advanced technology is that it allows doctors to deliver Intensity Modulated Radiation Therapy (IMRT) with precision and at a high speed.
1/9/2014· Purpose The aim of this study was to evaluate the feasibility and dose distribution of two different stereotactic body radiation therapy (SBRT) techniques, isocentric RapidArc (RA) and non-isocentric CyberKnife (CK), for the treatment of localized prostate cancer.
RapidArc VOLUMETRIC ARC THERAPY (VMAT) gives the Staten Island Radiation Oncology treating team the ability to deliver more tightly focused treatments to your cancer in a significantly shorter time. During a RapidArc™ VOLUMETRIC ARC THERAPY (VMAT) treatment the linear accelerator rotates around you and the radiation beams sweep in continuous uninterrupted arcs, tightly pin-pointed on the cancer.
intensity-modulated radiation therapy (IMRT) plans. To our knowledge, a dosimetric study comparing VMAT and proton planning for high-risk prostate cancer had yet to be performed. Recently, the VMAT has become a popular delivery option over IMRT for
RapidArc is an “IMRT Arc therapy” using a single rotation of the linac gantry to deliver a precise IMRT plan following IGRT and OBI targeting. This “volumetric arc,” often labeled VMAT, for Volumetric Arc Therapy, enhances both the delivery and the targeting of prostate cancer radiation.
Because the prostate is close to several vital structures, radiation therapy can disrupt normal urinary, bowel, and sexual functioning. Short-term Complications You may experience some temporary urinary symptoms, such as waking up in the night and needing to urinate, needing to urinate more often during the day, or urgency – needing to urinate right now, and not being able to hold it in for ...
