Table 3.

The cumulative AD over all cycles that would have been reached using alternative treatment strategy A (4 cycles to all) or estimated using alternative dosimetric methods (B–I) given the same no. of cycles as per protocol. “nd” indicates that the AD was not determined by that method

*Patients treated in step 2 (renal BED to (40 ± 2) Gy)

Grey indicates values that are within the estimated confidence interval for method P (AD for P ± 2SD). B: Planar dosimetry first cycle only. C: Planar dosimetry all cycles. D: Hybrid dosimetry first cycle only. E: Hybrid dosimetry first cycle and one SPECT/CT at 24 h in the following cycles. F: One SPECT/CT at 24 h in each cycle. G: One SPECT/CT at 96 h in all cycles. H: One SPECT/CT at 96 h first cycle only. I: Planar dosimetry at 96 h in all cycles. “No. of cycles”: the number of cycles actually given, based on method P
