<unk>  (RILP) or<unk><unk>  lumbosacral<unk>  (RILSP) is nerve damage in the pelvis and lower spine area caused by therapeutic<unk>  treatments. RILP is a rare side effect of external beam<unk>  therapy and both interstitial and intracavity brachytherapy<unk>  implants. In general terms, such nerve damage may present in stages, earlier as demyelination and later as complications of chronic<unk>  fibrosis. RILP occurs as a result of<unk>  therapy administered to treat lymphoma or cancers within the abdomen or pelvic area such as cervical, ovarian, bladder, colon, kidney, pancreatic, prostate, testicular, colorectal, colon, rectal or anal cancer. The lumbosacral plexus area is radiosensitive and<unk><unk>  can occur after exposure to mean or maximum<unk>  levels of 50-60 Gray with a significant rate difference noted within that range.
