Preview- It would appear that, the more precise setup of hypofractionated radiotherapy (i.e., radiation oncology) for prostate cancer patients is feasible with the implanted fiducial marker matching compared with the pelvic bony matching. Radiotherapy is the use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external (i.e., externus)-beam radiation therapy), or it may come from radioactive (i.e., radio-) material placed in the body near cancer cells (internal radiation therapy). Systemic radiotherapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that travels in the blood to tissues throughout the body. Also called irradiation and radiation therapy. Prostate cancer, cancer that forms in tissues of the prostate (a gland (i.e., glandula) in the male (i.e., masculine) reproductive system (i.e., genital system) found below the bladder and in front of the rectum). Prostate cancer usually occurs in older men. Pelvic, having to do with the pelvis (the lower (i.e., inferior, or lower tube (i.e., tuba)rcle) part of the abdomen (i.e., venter) located between the hip (i.e., hip bone, or hip joint) bones). Prostate is a gland in the male reproductive system. The prostate surrounds the part of the urethra (the tube that empties the bladder) just below the bladder, and produces a fluid that forms part of the semen (i.e., seed, or seminal fluid).
