Incomplete version for whole pelvic irradiation complying with RTOG0418
'A Phase II Study of Intensity Modulated Radiation Therapy (IMRT) to the Pelvis +/- Chemotherapy for Post-operative Patients with either Endometrial or Cervical Carcinoma '
Do not use this template in such prescribed dose, because some portion of bowel (especially small intestine) will be irradiate too high dose.
This trial shows several dose constraint. I try to make a plan complying with these constraint, but I cannot clear.
The prescription dose is the isodose which encompasses at least 97% of the vaginal PTV
and nodal PTV. No more than 20% of any PTV will receive > 110% of its prescribed dose.
This prototype: 91.7%. of PTV is encompassed by prescribed dose.
This prototype: 26% of PTV recieve >110%
No more than 1% of any PTV will receive < 93% of its prescribed dose.
This prototype: 1.13% receive < 93%
No more than 1% or1 cc (whichever is smaller) of the tissue outside the PTVs
will receive > 110% of the dose prescribed to the primary PTV.
Small bowel < 30% to receive >= 40 Gy, minor deviation 30% to 40 Gy
This prototype: 20%
Rectum < 60% to receive >= 30 Gy, minor deviation 35% to 50 Gy
This prototype: 69%
Bladder < 35% to receive >= 45 Gy, minor deviation 35% to 50 Gy
This prototype: 70%
