- We introduce and validate a new precision oncology framework for the systematic prioritization of drugs targeting mechanistic tumor dependencies in individual patients. Compounds are prioritized on the basis of their ability to invert the concerted activity of master regulator proteins that mechanistically regulate tumor cell state, as assessed from systematic drug perturbation assays. We validated the approach on a cohort of 212 gastroenteropancreatic neuroendocrine tumors (GEP-NETs), a rare malignancy originating in the pancreas and gastrointestinal tract. The analysis identified several master regulator proteins, including key regulators of neuroendocrine lineage progenitor state and immunoevasion, whose role as critical tumor dependencies was experimentally confirmed. Transcriptome analysis of GEP-NET-derived cells, perturbed with a library of 107 compounds, identified the HDAC class I inhibitor entinostat as a potent inhibitor of master regulator activity for 42% of metastatic GEP-NET patients, abrogating tumor growth in vivo. This approach may thus complement current efforts in precision oncology.

- Aims To investigate the role of guidelines in structuring the clinical care for adult patients with congenital heart disease (CHD), and to assess adherence to the guidelines in Europe. Methods and results A selected number of current guidelines were chosen pertaining to operative procedures, investigations, and the use of medication ('interventions'). The source for this analysis was the database of the Euro Heart Survey on adult CHD, which contains retrospectively collected data on 4110 patients followed-up for a median of 5.1 years. For each guideline investigated, patients were selected from the database for whom the particular guideline was relevant. The selected cases were classified according to two criteria: was there an indication for the particular intervention and did the intervention take place? In this manner, cases of 'undue treatment' and 'insufficient treatment' were identified. Adherence to guidelines was found to be good in the case of operative procedures and prophylactic drug treatment. However, regarding diagnostic procedures there had been adherence to guidelines in only slightly more than half of the cases. Conclusion Guidelines have an important role in the actual clinical care of adults with CHD. However, large outcome studies are needed to develop more precise guidelines.

- Aims To describe clinical and demographic characteristics at baseline of a European cohort of adults with congenital heart disease (CHD) and to assess mortality and morbidity in a 5 year follow-up period. Methods and results Data collected as part of the Euro Heart Survey on adult CHD was analysed. This entailed information transcribed from the files of 4110 patients diagnosed with one of eight congenital heart conditions ('defects'), who consecutively visited the outpatient clinics of one of the participating centres in 1998. The patients were included retrospectively and followed until the end of 2003 for a median follow-up of 5.1 years. Notwithstanding their overall relatively good functional class and low mortality over the follow-up period, a considerable proportion of the patients had a history of endocarditis, arrhythmias, or vascular events. There were major differences between the eight defects, both in morbidity and regarding specific characteristics. Outcomes were worst in cyanotic defects and in the Fontan circulation, but a considerable proportion of the other patients also suffer from cardiac symptoms. In particular, arrhythmias are common. Conclusion The spectrum of adult CHD in Europe emerging from this survey is one of a predominantly young population with substantial morbidity but relatively low mortality in a 5 year period.
