Is IMRT effective for prostate cancer?
Conclusion: Treatment of localized prostate cancer using IMRT with a dose 78/82 Gy yielded an excellent 5-year tumour control with a risk of clinical relapse being less than 5%.
How long do side effects last after prostate radiation?
After completing external beam radiation therapy (EBRT), urinary and bowel side effects may persist for two to six weeks, but they will improve over time. You may need to continue some medications.
What is the most common acute side effect of radiation treatment?
The most common early side effects are fatigue (feeling tired) and skin changes. Other early side effects usually are related to the area being treated, such as hair loss and mouth problems when radiation treatment is given to this area.
What are the disadvantages of IMRT?
The biggest defect associated with IMRT is increase in total body irradiation. IMRT saves OARs from receiving high radiation dose but at the same time delivers lower dose to the less critical organs. This technique spread out the delivered dose to the whole body and increases the total body exposure.
What is the most successful prostate cancer treatment?
Radiation therapy is a good choice for many men with early-stage prostate cancer. It is also the best treatment for older men or those who have other health problems. There are different types of radiation therapy: External beam radiation.
How long does IMRT treatment take?
How long do IMRT sessions generally last? Most treatment sessions take between 10 and 30 minutes.
What should PSA be after radiation?
Recent studies have shown that for optimal results, PSA levels should be lower than 1 ng/ml, and even lower than 0.5 ng/ml. Levels that are above 1 or 2 ng/ml 12 to 18 months following completion of radiation treatments are very worrisome, because they indicate that the cancer may not have been eradicated.

Does radiation shorten your life?
“Rapidly dividing cells, such as cancer cells, are more affected by radiation therapy than normal cells. The body may respond to this damage with fibrosis or scarring, though this is generally a mild process and typically does not cause any long-term problems that substantially affect quality of life.”
Is IMRT a proton therapy?
Intensity-modulated radiation therapy (IMRT) is an advanced type of radiation therapy used to treat cancer and noncancerous tumors. IMRT uses advanced technology to manipulate photon and proton beams of radiation to conform to the shape of a tumor.
Where is the target margin for prostate cancer?
Planning Target Volume (PTV) 6mm margin around CTV 3mm posterior margin used for hypofractionated treated patients and seeded patients receiving supplemental EBRT Superior border at tips of the SV Inferior border above penile bulb prostate apex generally 1.2 cm above the penile bulb
How big is the PTV margin for prostate cancer?
•In 2008 gold fiducials routinely placed for all definitive prostate cancer IMRT. •During this time our PTV margins were maintained as 1 cm except at the prostate- rectal interface where a 6 mm margin used.
What are some common errors in prostate contouring?
Common Errors in Prostate Contouring • Overestimating the extent of the apex • Underestimating the extent of the base • Widening contours to include levator muscles or peri-prostatic tissues and ligaments Identification of the Prostatic Apex
