Treatment results of AML in elderly patients are unsatisfactory. In an open label randomized phase II study, we investigated whether addition of the XPO1 inhibitor selinexor to intensive chemotherapy would improve outcome in this population. 102 AML patients > 65 years of age (median 69 (65–80)) were randomly assigned to standard chemotherapy (3 + 7) with or without oral selinexor 60 mg twice weekly (both arms n = 51), days 1–24. In the second cycle, cytarabine 1000 mg/m2 twice daily, days 1–6 with or without selinexor was given. CR/CRi rates were significantly higher in the control arm than in the investigational arm (80% (95% C.I. 69–91%) vs. 59% (45–72%; p = 0.018), respectively). At 18 months, event-free survival was 45% for the control arm versus 26% for the investigational arm (Cox-p = 0.012) and overall survival 58% vs. 33%, respectively (p = 0.009). AML and infectious complications accounted for an increased death rate in the investigational arm. Irrespective of treatment, MRD status after two cycles appeared to be correlated with survival. We conclude that the addition of selinexor to standard chemotherapy does negatively affect the therapeutic outcome of elderly AML patients.

Background: Most invasive procedures require the interruption of oral anticoagulation. In 2015, an international randomised trial demonstrated that perioperative bridging caused more harm than benefit in most anticoagulated patients with atrial fibrillation, leading to a more restrictive Dutch national guideline in April 2016. The objective of the present study was to analyse the integration of the 2016 Dutch guideline for perioperative antithrombotic management from after publication until update of hospital protocols. Methods: This is a retrospective cohort study of patients on vitamin K antagonists undergoing a surgical procedure between April 2016 and June 2017. Results: The proportion of high-risk patients with venous thromboembolism or atrial fibrillation receiving bridging therapy decreased from 91% and 77%, respectively at the start of the study to 33% in both groups in the last months. In high-risk patients with a mechanical heart valve, the bridging rate remained stable at 70-80% for 12 months and increased to 100% in the last 3 months. Protocol adherence for high-risk patients decreased from 80% to below 43%. The 30-day incidence of major bleeding was 4.1% (15.2% in bridged patients and 0.7% in non-bridged patients) and 10.3% for clinically relevant non-major bleeding (23.9% in bridged patients and 6.0% in non-bridged patients). The incidence of thrombo-embolism was 0.5%. Conclusion: New evidence from the Dutch national guideline on perioperative bridging was adopted by physicians before the local hospital protocol was updated. Low incidence of thromboembolism in non-bridged patients and high incidence of bleeding in bridged patients support a more restrictive bridging policy.

Introduction We previously reported the results of the phase III randomized HOVON-87/NMSG-18 study for Newly Diagnosed Multiple Myeloma patients not eligible for stem cell transplantation (nte-NDMM). The efficacy of melphalan, prednisolone and either thalidomide followed by thalidomide maintenance (MPT-T) versus lenalidomide followed by lenalidomide maintenance (MPR-R) was found to be comparable, being consistent across subgroups defined by age, cytogenetic risk and ISS [1]. As frailty is known to affect clinical outcome, we investigated the impact of frailty on outcome. Methods Frailty was assessed by a modification of the IMWG frailty score based on age, the Charlson Comorbidity Index (retrospectively retrieved from the list of comorbidities that were present at entry) and the WHO performance as a proxy for (instrumental) Activities of Daily Living ((i)ADL). To assess the effect of frailty on progression free survival (PFS) and OS, the logrank test was used, while the chi-squared test was used to evaluate the association of frailty with discontinuation rate and toxicity. Results All 637 eligible patients from the HOVON-87/NMSG-18 trial were included in the analysis. Median age was 73 years; 66% of patients were 80 years. A CCI of 0, 1, 2 and >=3 was found in 61, 20, 7 and 4% of patients respectively (8% unknown). The most common comorbidities were diabetes mellitus without end organ complications (12%) and myocardial infarction (6%). A WHO performance of 0, 1 and >= 2 was observed in 35, 47 and 16% respectively (3% unknown). Univariate analyses showed that older age (>80 years: HR 1.59 [95% CI 1.12-2.25]), a higher CCI (CCI >=2: HR 1.41 [95% CI 1.01-1.95]); and a poor WHO performance (WHO >=2: HR 2.05 [1.49-2.82]) were associated with an inferior OS. HR's were 1.07 [95% CI 0.82-1.40] and 1.27 [95% CI 0.98- 1.65] for age 76-80 years and WHO performance respectively. For age and the CCI the IMWG frailty score classification was used. For the WHO, scores were assigned based on the HR: WHO 0; 0 points, WHO 1; 1 point and WHO >=2; 2 points. Fit patients were defined as a proxy frailty score of 0, unfit as a score of 1 and frail as a score of >=2, comparable to the IMWG frailty score. Using this modified IMWG frailty score, 135 patients were fit (21%), 199 were unfit (31%) and 259 were frail (41%) (7% unknown). The median OS was found to be significantly different in fit versus unfit versus frail patients; 58, 55 and 46 months respectively (p=0.004). In contrast no significant difference in median PFS was found; 26, 20 and 21 months respectively (p=0.30). The inferior OS for the frail might be partly explained by higher discontinuation rate of induction therapy; 50%, versus 43% in unfit, and 34% in fit patients (p=0.011), being mainly due to excessive toxicity (25, 23 and 16% respectively). The cumulative incidence of treatment discontinuation on protocol (induction plus maintenance), corrected for death and progressive disease which were considered as competing risks, is depicted in figure 1B. Discontinuation rate at 2 years for fit, unfit, and frail patients were 48%, 48%, and 59% respectively (p=0.06). There were significantly more grade >=3 adverse events on protocol in frail and unfit patients (both 86%) as compared to fit patients (77%, p=0.039). Especially more grade >=3 infections were found in frail (28% versus 18% in unfit and 13% in fit). In contrast, frailty was not associated with hematological toxicity. Conclusion We here present a modified frailty score, using the WHO performance instead of the (i)ADL, combined with age and the CCI, that enables the identification of frail MM patients with an inferior OS, a higher discontinuation rate and a higher rate of grade >= 3 toxicity. This non-laborious modified frailty score can be easily implemented in clinical trials and allows to compare the outcome of frail patients in nte-NDMM trials, which will hopefully result in frailty-adapted therapy in clinical daily practice.

Our aim was to determine whether dexamethasone results in a better outcome than prednisolone. DESIGN AND METHODS: Adult patients with acute lymphoblastic leukemia or lymphoblastic lymphoma were randomized to receive, as part of their induction therapy on days 1-8 and 15-22, either dexamethasone 8 mg/m(2) or prednisolone 60 mg/m(2). Those who reached complete remission were given two courses of consolidation therapy with high-dose cytarabine and mitoxantrone and methotrexate and asparaginase. Subsequently patients younger than 50 years, with a suitable donor, were to undergo allogeneic stem cell transplantation, whereas the others were planned to receive either an autologous stem cell transplant or high-dose maintenance chemotherapy with prophylactic central nervous system irradiation. Randomization was done with a minimization technique. The primary endpoint was event-free survival and the analyses was conducted on an intention-to-treat basis. RESULTS: Between August 1995 and October 2003, 325 patients between 15 to 72 years of age were randomized to receive either dexamethasone (163 patients) or prednisolone (162 patients). After induction and the course of first consolidation therapy, 131 (80.4%) patients in the dexamethasone group and 124 (76.5%) in the prednisolone group achieved complete remission. No significant difference was observed between the two treatment groups with regards to 6-year event-free survival rates (+/-SE) which were 25.9% (3.6%) and 28.7% (3.5%) in the dexamethasone and prednisolone groups, respectively (P=0.82, hazard ratio 0.97; 95% confidence interval, 0.75-1.25). Disease-free survival after complete remission was also similar in the dexamethasone and prednisolone groups, the 6-year rates being 32.3% and 37.5%, respectively (hazard ratio 1.03; 95% confidence interval 0.76-1.40). The 6-year cumulative incidences of relapse were 49.8% and 53.5% (Gray's test: P=0.30) while the 6-year cumulative incidences of death were 18% and 9% (Gray's test: P=0.07). CONCLUSIONS: In the ALL-4 trial in adult patients with acute lymphoblastic leukemia or lymphoblastic lymphoma, treatment with dexamethasone did not show any advantage over treatment with prednisolone. 01 september 2010
