2. The moving-strip and open-field techniques are equally effective, but the latter is preferred.
3. No liver shielding is used. The limits the upper abdominal dose to 2,500 to 2,800 cGy in 100 to 120 cGY daily fractions.
4. Partial kidney shielding is used to keep the renal dose at 1,800 to 2,000 cGY.
5. The true pelvis is given a boost dose in 180 to 220 cGY fractions to a total dose of 4,500 to 5,000 cGY.
6. Use parallel-opposing portals, with beam energy sufficient to sure a dosage variation no greater than 5%.
