Tumor-Absorbed Dose and Metabolic Tumor Response
| Baseline/outcome measure | Individual metastases (n = 113) | Sum of all metastases within liver (n = 30) |
| Mean tumor-absorbed dose ± SD | 51 ± 28 Gy (range, 7–174) | 57 ± 26 Gy (range, 18–109) |
| Median baseline TLG* | 177 (range, 28–5,891; IQR, 459) | 1350 (range, 181–5,891; IQR, 2,212) |
| Posttreatment TLG* at 1m FU | 115 (range, 0–7,111; IQR, 478) | 1,016 (range, 0–7,341; IQR, 2,786) |
| Metabolic response rate | 52/113 (46%) | 11/30 (37%) |
Tumor-absorbed dose and metabolic tumor response results on level of individual metastases (n = 113) and for sum of all metastases per liver (n = 30). Data are mean ± SD, with range in parentheses; median, with range and interquartile range (IQR) in parentheses; or n, with percentages in parentheses.
