A new method to reduce rectal radiation injury in prostate cancer patients involves the use of an absorbable spacer placed between the prostate and rectum. MRI showing hydrogel spacer pushing the rectum away from the prostate during radiotherapy. Such spacers are commercially available in some regions and are undergoing clinical trials in ...

In the Nigro protocol, the patient receives 30 Gy (3000 rads) of radiation over a three-week period, as well as continuous administration of fluorouracil for the first four days and on days 20–31, with bolus mitomycin ...
Radiation enteropathy is a syndrome that may develop following abdominal or pelvic radiation therapy for cancer. [ 1 ] [ 2 ] Many affected people are cancer survivors who had treatment for cervical cancer or prostate cancer .
Body sites in which brachytherapy can be used to treat cancer. Brachytherapy is commonly used to treat cancers of the cervix, prostate, breast, and skin.

Drainage catheter placement: Placement of tubes to drain pathologic fluid collections (e.g., abscess, pleural effusion). This may be achieved by percutaneous, trans-rectal, or trans-vaginal approach. Exchange or repositioning of indwelling catheters is achieved over a guidewire under image guidance.
The commonly used number of radiation sessions can be cut by half in mastectomy patients who need the treatment before breast reconstruction, according to a study reported at a large meeting of ...
