Show moreBackground In clinical practice and science, there is debate for which older adults the benefits of cardiovascular preventive medications (CPM) still outweigh the risks in older age. Therefore, we aimed to assess how various clinical characteristics influence the judgement of appropriateness of CPM in older adults. Method We assessed the appropriateness of CPM for adults >= 75 years with regard to clinical characteristics (cardiovascular variables, complexity of health problems, age, side effects and life expectancy) using the RAND/ University of California at Los Angeles Appropriateness Method. A multidisciplinary panel, including 11 medical professionals and 3 older representatives of the target population, received an up-to-date overview of the literature. Using 9-point Likert scales (1 = extremely inappropriate; 9 = extremely appropriate), they assessed the appropriateness of starting and stopping cholesterol lowering medication, antihypertensives and platelet aggregation inhibitors, for various theoretical clinical scenarios. There were two rating rounds, with one face-to-face discussion in between. The overall appropriateness judgments were based on the median panel ratings of the second round and level of disagreement. Results The panelists emphasized the importance of the individual context of the patient for appropriateness of CPM. They judged that in general, a history of atherosclerotic cardiovascular disease strongly adds to the appropriateness of CPM, while increasing complexity of health problems, presence of hindering or severe side effects, and life expectancy < 1 year all contribute to the inappropriateness of CPM. Age had only minor influence on the appropriateness judgments. The appropriateness judgments were different for the three types of CPM. The literature, time-to-benefit, remaining life expectancy, number needed to treat, and quality of life, were major themes in the panel discussions. The considerations to stop CPM were different from the considerations not to start CPM. Conclusion Next to the patients' individual context, which was considered decisive in the final decision to start or stop CPM, there were general trends of how clinical characteristics influenced the appropriateness, according to the multidisciplinary panel. The decision to stop, and not start CPM, appeared to be two distinct concepts. Results of this study may be used in efforts to support clinical decision making about CPM in older adults. Show less

Show moreBackground: Beyond first-line palliative systemic treatment can be beneficial to selected oesophagogastric cancer patients, but experience with its administration may be limited and vary among hospitals. In a population-based study, we analysed the association between hospital systemic treatment volume and administration of beyond first-line treatment in oesophagogastric adenocarcinoma, as well as the effect on overall survival (OS).Methods: Synchronous metastatic oesophagogastric adenocarcinoma patients (2010-2017) were selected from the Netherlands Cancer Registry. Hospitals were categorised in volumes quartiles. The association between hospital systemic treatment volume and the use of beyond first-line treatment was assessed using trend and multivariable logistic regression analyses. OS was compared between hospitals with high and low beyond first-line treatment administration and treatment strategies using Kaplan-Meier curves with log-rank test and multivariable Cox proportional hazard regression.Results: Beyond first-line treatment was administered in 606 of 2,466 patients who received first-line treatment, and increased from 20% to 31% between 2010 and 2017 (P < 0.001). The lowest hospital volumes were independently associated with lower beyond first-line treatment administration compared to the highest volume (OR 0.62, 95% CI 0.39-0.99; OR 0.67, 95% CI 0.48-0.95). Median OS was higher in all patients treated in hospitals with a high versus low beyond first-line treatment administration (7.9 versus 6.2 months, P < 0.001). Second-line paclitaxel/ramucirumab was administered most frequently and independently associated with longer OS compared to taxane monotherapy (HR 0.74, 95% CI 0.59-0.92).Conclusion: Higher hospital volume was associated with increased beyond first-line treatment administration in oesophagogastric adenocarcinoma. Second-line paclitaxel/ramucirumab resulted in longer survival compared to taxane monotherapy. (C) 2020 The Authors. Published by Elsevier Ltd. Show less

Show moreBackground Addition of trastuzumab to first-line palliative chemotherapy in gastroesophageal cancer patients with HER2 overexpression has shown to improve survival. Real-world data on HER2 assessment and administration of trastuzumab are lacking. The aim of this study was to assess HER2 testing, trastuzumab administration, and overall survival (OS) in a nationwide cohort of metastatic gastroesophageal cancer patients. Methods Data of patients with synchronous metastatic gastroesophageal adenocarcinoma diagnosed in 2010-2016 that received palliative systemic treatment (n = 2846) were collected from the Netherlands Cancer Registry and Dutch Pathology Registry. The ToGA trial criteria were used to determine HER2 overexpression. Proportions of HER2 tested patients were analyzed between hospital volume categories using Chi-square tests, and over time using trend analysis. OS was tested using the Kaplan Meier method with log rank test. Results HER2 assessment increased annually, from 18% in 2010 to 88% in 2016 (P < 0.01). Median OS increased from 6.9 (2010-2013) to 7.9 months (2014-2016;P < 0.05). Between the hospitals, the proportion of tested patients varied between 29-100%, and was higher in high-volume hospitals (P < 0.01). Overall, 77% of the HER2 positive patients received trastuzumab. Median OS was higher in patients with positive (8.8 months) and negative (7.4 months) HER2 status, compared to non-tested patients (5.6 months;P < 0.05). Conclusion Increased determination of HER2 and administration of trastuzumab have changed daily practice management of metastatic gastroesophageal cancer patients receiving palliative systemic therapy, and possibly contributed to their improved survival. Further increase in awareness of HER2 testing and trastuzumab administration may improve quality of care and patient outcomes. Show less
