Precision oncology for intrahepatic cholangiocarcinoma in clinical practice.

BACKGROUND: Advanced cholangiocarcinoma has a poor prognosis. Molecular targeted approaches have been proposed for patients after progression under first-line chemotherapy treatment. Here, molecular profiling of intrahepatic cholangiocarcinoma in combination with a comprehensive umbrella concept was applied in a real-world setting. METHODS: In total, 101 patients received molecular profiling and matched treatment based on interdisciplinary tumour board decisions in a tertiary care setting. Parallel DNA and RNA sequencing of formalin-fixed paraffin-embedded tumour tissue was performed using large panels. RESULTS: Genetic alterations were detected in 77% of patients and included gene fusions in 21 patients. The latter recurrently involved the FGFR2 and the NRG1 gene loci. The most commonly altered genes were BAP1, ARID1A, FGFR2, IDH1, CDKN2A, CDKN2B, PIK3CA, TP53, ATM, IDH2, BRAF, SMARCA4 and FGFR3. Molecular targets were detected in 59% of patients. Of these, 32% received targeted therapy. The most relevant reason for not initiating therapy was the deterioration of performance status. Patients receiving a molecular-matched therapy showed a significantly higher survival probability compared to patients receiving conventional chemotherapy only (HR: 2.059, 95% CI: 0.9817-4.320, P < 0.01). CONCLUSIONS: Molecular profiling can be successfully translated into clinical treatment of intrahepatic cholangiocarcinoma patients and is associated with prolonged survival of patients receiving a molecular-matched treatment.

Refusing the information paradigm: informed consent, medical research, and patient participation.

This article challenges the assumption that patient autonomy can best be assured by providing proper information through formalized procedures such as informed consent. We suggest that to understand and consider laypeople's ways of knowing and decision making, one has to move beyond the information paradigm and take into account a much broader context. Concretely, we investigate informed consent in connection with donating skin tissue remaining from medically indicated surgery. We use interviews with patients and observation protocols to analyse patients' perceptions and ways of making sense of informed consent beyond its bioethical ideal. Patients situate themselves in a larger system of solidarity, enroll in an overall positive image of science as a linear process of innovation oriented towards output, and simultaneously take a pragmatic stance towards hospital routines as a necessary passage point towards receiving good treatment. Because informed consent is one of the central articulations between the biomedical system and society, we conclude by reflecting on the consequences of our findings on a socio-political level.
