    • Objective: To evaluate the oncological outcome for patients with colorectal liver metastases (CRLM) randomized to associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) or 2-stage hepatectomy (TSH). Background: TSH with portal vein occlusion is an established method for patients with CRLM and a low volume of the future liver remnant (FLR). ALPPS is a less established method. The oncological outcome of these methods has not been previously compared in a randomized controlled trial. Methods: One hundred patients with CRLM and standardized FLR (sFLR) <30% were included and randomized to resection by ALPPS or TSH, with the option of rescue ALPPS in the TSH group, if the criteria for volume increase was not met. The first radiological follow-up was performed approximately 4 weeks postoperatively and then after 4, 8, 12, 18, and 24 months. At all the follow-ups, the remaining/recurrent tumor was noted. After the first follow-up, chemotherapy was administered, if indicated. Results: The resection rate, according to the intention-to-treat principle, was 92% (44 patients) for patients randomized to ALPPS compared with 80% (39 patients) for patients randomized to TSH (P = 0.091), including rescue ALPPS. At the first postoperative follow-up, 37 patients randomized to ALPPS were assessed as tumor free in the liver, and also 28 patients randomized to TSH (P = 0.028). The estimated median survival for patients randomized to ALPPS was 46 months compared with 26 months for patients randomized to TSH (P = 0.028). Conclusions: ALPPS seems to improve survival in patients with CRLM and sFLR <30% compared with TSH.

  • Skin sensitization in silico protocol
  • 2020
  • Ingår i: Regulatory toxicology and pharmacology. - : Elsevier BV. - 0273-2300 .- 1096-0295. ; 116
  • Tidskriftsartikel (refereegranskat)abstract
    • The assessment of skin sensitization has evolved over the past few years to include in vitro assessments of key events along the adverse outcome pathway and opportunistically capitalize on the strengths of in silico methods to support a weight of evidence assessment without conducing a test in animals. While in silico methods vary greatly in their purpose and format; there is a need to standardize the underlying principles on which such models are developed and to make transparent the implications for the uncertainty in the overall assessment. In this contribution, the relationship between skin sensitization relevant effects, mechanisms, and endpoints are built into a hazard assessment framework. Based on the relevance of the mechanisms and effects as well as the strengths and limitations of the experimental systems used to identify them, rules and principles are defined for deriving skin sensitization in silico assessments. Further, the assignments of reliability and confidence scores that reflect the overall strength of the assessment are discussed. This skin sensitization protocol supports the implementation and acceptance of in silico approaches for the prediction of skin sensitization.
