- Background: Gastroenteropancreatic neuroendocrine carcinomas (GEP-NEC) are generally characterized by synchronous metastases, high aggressiveness and a dismal prognosis. Current international guidelines do not recommend surgical treatment of liver metastases, however the existing data are scarce. The aim of this study was to evaluate the results of curatively intended resection/radiofrequency ablation (RFA) of liver metastases in patients with metastatic GEP-NEC. Methods: 32 patients with a diagnosis of high-grade gastroenteropancreatic neuroendocrine neoplasm (Ki-67 > 20%) and with intended curative resection/RFA of liver metastases, were identified among 840 patients from two Nordic GEP-NEC registries. Tumor morphology (well vs poor differentiation) was reassessed. Overall survival (OS) and progression-free survival (PFS) was assessed by Kaplan Meier analyses for the entire cohort and for subgroups. Results: Median OS after resection/RFA of liver metastases was 35.9 months (95% -CI: 20.6-51.3) with a five-year OS of 43%. The median PFS was 8.4 months (95% -CI: 3.9-13). Four patients (13%) were disease -free after 5 years. Two patients had well -differentiated morphology (NET G3) and 20 patients (63%) had Ki-67 >= 55%. A Ki-67 < 55% and receiving adjuvant chemotherapy were statistically significant factors of improved OS after liver resection/RFA. Conclusion: This study shows a long median and long term survival after liver surgery/RFA for these selected metastatic GEP-NEC patients, particularly for the group with a Ki-67 in the relatively lower G3 range. Our findings indicate a possible role for surgical treatment of liver metastases in the management of this patient population.

- In amyotrophic lateral sclerosis (ALS) cognitive impairment may occur. This could detrimentally influence communication between patient and health-care professionals and make clinical assessment difficult. Given the short life expectancy after diagnosis, it is crucial to accurately identify ALS patients early. Although suitable cognitive screening tools for patients with ALS are available, they have not been evaluated in a Norwegian population. Interpretation of scores for available tests and practical application of scoring is also not well established. The protocol described here involves two related studies that aim to improve the quality of ALS clinical testing instruments used in the Norwegian population. The first is a validation study that evaluates the psychometric properties of the ECAS-Norwegian. The second is a prospective cohort study that evaluates the ECAS-Norwegian as a tool to predict early changes in ability to work, drive a car and the need for advanced therapy. Study 1 is a multicenter study using international quality criteria. Patients with ALS, healthy control subjects, and control subjects with dementia will be included. Primary outcome is ECAS-Norwegian scores. In study 2, patients with ALS will be included. ECAS-Norwegian compared to Clinical Dementia Rating score and Montreal Cognitive Assessment scores will be used as a prognostic tool for working, driving, and initiating advanced life-prolonging therapy. Before clinical implementation, the ECAS-Norwegian needs to be evaluated and validated. Successful validation and implementation of the ECAS-Norwegian may provide early identification of cognitive impairment in ALS, leading to more proactive, individualized treatment.
