Potential improvement in the results of irradiation for prostate carcinoma using improved dose distribution

摘要: Results for radiation treatment of prostate carcinoma indicate that nearly one-third Stage C patients fail locally. This number will likely increase as occult failures are discovered by monitoring serum specific antigen levels. Thus, there is need techniques would the local control prostatic carcinoma. Using cross-sectional imaging and 3-dimensional planning, dose distributions photon irradiation can be created conform more closely to shape seminal vesicles, sparing additional portions bladder rectum. A escalation trial underway investigate whether these lead increased without unacceptable increases in rectal complications. While zero probably an unattainable goal, reduction failure cancer overall cure rate this disease.
