- Study Purpose The DRAGON 1 trial aims to assess training, implementation, safety and feasibility of combined portal- and hepatic-vein embolization (PVE/HVE) to accelerate future liver remnant (FLR) hypertrophy in patients with borderline resectable colorectal cancer liver metastases. Methods The DRAGON 1 trial is a worldwide multicenter prospective single arm trial. The primary endpoint is a composite of the safety of PVE/HVE, 90-day mortality, and one year accrual monitoring of each participating center. Secondary endpoints include: feasibility of resection, the used PVE and HVE techniques, FLR-hypertrophy, liver function (subset of centers), overall survival, and disease-free survival. All complications after the PVE/HVE procedure are documented. Liver volumes will be measured at week 1 and if applicable at week 3 and 6 after PVE/HVE and follow-up visits will be held at 1, 3, 6, and 12 months after the resection. Results Not applicable. Conclusion DRAGON 1 is a prospective trial to assess the safety and feasibility of PVE/HVE. Participating study centers will be trained, and procedures standardized using Work Instructions (WI) to prepare for the DRAGON 2 randomized controlled trial. Outcomes should reveal the accrual potential of centers, safety profile of combined PVE/HVE and the effect of FLR-hypertrophy induction by PVE/HVE in patients with CRLM and a small FLR.

- Background: Associated liver partition and portal vein ligation in staged hepatectomy (ALPPS) is an alternative resection method to portal vein embolization (PVE) in patients with small future liver remnants (FLR) but has been associated with early tumor recurrences. Methods: Twenty-four patients with colorectal liver metastases (CRLM) patients from the randomized multicenter LIGRO trial comparing outcome of ALPPS (n = 13) vs PVE (n = 11) were included in the study. Mutational analyses of the KRAS, NRAS, BRAF, PIC3CA and TP53 genes of the metastases were performed in 21 patients and correlated to early tumor recurrence. Results: Within 12 months, 13 patients experienced recurrences (6 in TSH group and 7 in ALPPS group). Nine of 13 patients with recurrences had mutations in the TP53 gene, while 3 of 8 patients without recurrence carried the same mutation. Only sporadic cases of the other mutations studied were identified. Conclusions: ALPPS did not appear to be associated with higher rate of rapid recurrences than PVE following radical resection of colorectal liver metastases. Mutations in genes associated with negative oncologic outcome after surgical resection most likely play a role for tumor recurrences in these patients.

- A prototype of the Transition Radiation Tracker (TRT) for the ATLAS experiment at the CERN LHC has been built and tested at the CERN SPS. Detailed studies of the drift-time measurements, alignment technique, hit registration efficiency, track and momentum accuracy were performed. A coordinate measurement accuracy of 150 Pin for a single TRT drift tube and momentum resolution of 0.8% for 20 GeV pions in a 1.56 T magnetic field were achieved. The results obtained are in agreement with the expected tracking performance of the ATLAS TRT. (C) 2001 Published by Elsevier Science B.V.
