Three-dimensional conformal radiation therapy in locally advanced carcinoma of the prostate: Preliminary results of a phase I dose-escalation study

Primary Radiation Therapy in the Treatment of Localized Prostatic Cancer

“…The Stanford University material now includes over 900 patients, the majority being early stage (Tl-T2) cases, and over 15 years' follow-up (1 I). These original results have been confirmed in many other series (12)(13)(14)(15)(16)(17)(18)(19)(20).…”

Dose Delivery Accuracy of Therapeutic Photon and Electron Beams at Low Monitor Unit Settings

“…Segmental and hyperfractionated radiotherapy are usually delivered with < 50 MU settings [5,13]. The conformal therapy makes use of multiple multileaf collimated (MLC) beams of varying intensities delivered with automatic computer controls [14][15][16]. Sometimes the number of MU per field might vary as low as 10 MU depending on the location of the target and the neighboring normal structures [1,8,17,18,25].…”

Conformal Radiotherapy for Prostate Cancer&Longer Duration of Acute Genitourinary Toxicity in Patients with Prior History of Invasive Urological Procedure

“…The 'high-dose volume' of critical structures (rectum and bladder), covered by 90% isodose, can be reduced by more than 40% in comparison with conventional techniques (1). Several retrospective studies showed, that the dosimetric advantages of 3D-CRT were associated with acute morbidity reduction (2)(3)(4).…”
