Tumour volumetry in the right lobe in patients who did and did not undergo portal vein embolization (PVE)
| PVE (n = 109) | No PVE (n = 11) | P-value | |
|---|---|---|---|
| Tumour volume, cm3, median (range) | |||
| First CT scana | 21.2 (4.5–76.4) | 10.6 (3.2–14.8) | 0.080 |
| Second CT scan | 34.8 (11.5–112) | 6.6 (2.0–9.9) | < 0.001 |
| P-valueb | < 0.001 | 0.002 | |
| Change in tumour volume, % (range) | 33.4 (− 0.5 to 168.0) | − 34.8 (− 40.7 to − 26.1) | < 0.001a |
a
Tumour volumes calculated from first and second CT scans (with embolization during interval time for study group only).
b
Difference between pre- and post-embolization values.
CT, computed tomography.
