Fox Chase researchers improve accuracy of IMRT delivery in post-prostatectomy patients:NCI Cancer Center News
A new study led by researchers at Fox Chase Cancer Center has revealed that a portion of the prostate bed is located outside IMRT treatment margins in a significant percentage of post-prostatectomy patients, suggesting that they may be receiving too little treatment in the appropriate area and too much in surrounding structures during the course of their treatment. The most common technique of post-prostatectomy radiation is Intensity Modulated Radiation Therapy (IMRT), in which radiation beams closely conform to the area of interest while sparing normal adjacent healthy structures. To ensure its optimal effectiveness in post-prostatectomy patients, clinicians should precisely deliver the radiation beams to the prostate bed and avoid crucial structures such as the bladder and rectum.
Among the research institutions NCI funds across the United States, it currently designates 66 as Cancer Centers. Largely based in research universities, these facilities are home to many of the NCI-supported scientists who conduct a wide range of intense, laboratory research into cancer’s origins and development. The Cancer Centers Program also focuses on trans-disciplinary research, including population science and clinical research. The centers’ research results are often at the forefront of studies in the cancer field.
