Experimental Radiation or Other Nonsurgical Procedures
Investigators are testing radiation treatments that use a combination of neutrons and protons (mixed-beam) or proton beams rather than the standard proton radiation therapy. Intensity-modulated radiation therapy is a promising technique that delivers different doses to multiple target areas using images of specific regions.
High-Intensity Focused Ultrasound (HIFU). Studies are reporting promise results with an intensive ultrasound procedure called transrectal high-intensity focused ultrasound (HIFU). It allows for very precise minimally invasive removal of tissue in local prostate cancers. It may eventually prove to be an alternative to radiation therapy. More research, with long-term follow up, is needed.
Radiofrequency. Radiofrequency is being used to heat and destroy the prostate. Early studies suggest that this is a promising approach.
