Abstract:Conformal radiotherapy is a relatively new high‐precision treatment planning and delivery technique that requires much quality assurance, mostly during its implementation. Our study involved the eight centers participating in the French phase II dose escalation study with conformal radiotherapy for the cancer of the prostate. The dose escalation protocol consisted of five dose levels (66, 70, 74, 78, and 80 Gy ICRU prescription dose). The quality assurance topics examined are the following: (1) the target volu… Show more
“…Special attention was devoted to volume delineation, because it was the greatest factor of uncertainty in the escalation dose study (24). Analysis of the DVHs from the previous study permitted the definition of acceptable constraints.…”
