Survival continues to increase in chronic lymphocytic leukaemia: a population-based analysis among 20Â 468 patients diagnosed in the Netherlands between 1989 and 2016
Possible hampered effectiveness of second-line treatment with rituximab-containing chemotherapy without signs of rituximab resistance: a population-based study among patients with chronic lymphocytic leukemia
Rituximab-containing chemotherapy remains a viable frontline treatment option for patients with chronic lymphocytic leukemia (CLL) in the era of novel agents. However, its effectiveness in the second-line setting—in relation to previous rituximab exposure in first-line—has hardly been evaluated in a population-based setting. Therefore, in this comprehensive, population-based study, we assessed the impact of first-line treatment with rituximab-containing chemotherapy on the effectiveness of second-line treatment with rituximab-containing chemot

Proteomic markers with prognostic impact on outcome of chronic lymphocytic leukemia patients under chemo-immunotherapy: results from the HOVON 109 study
Despite recent identification of several prognostic markers, there is still a need for new prognostic parameters able to predict clinical outcome in chronic lymphocytic leukemia (CLL) patients. Here, we aimed to validate the prognostic ability of known (proteomic) markers measured pretreatment and to search for new proteomic markers that might be related to treatment response in CLL. To this end, baseline serum samples of 51 CLL patients treated with chemo-immunotherapy were analyzed for 360 proteomic markers, using Olink technology. Median event-free survival (EFS) was 23 months (range: 1.25–60.9). Patients with high levels of sCD23 (>11.27, p = 0.026), sCD27 (>11.03, p = 0.04), SPINT1 (>1.6, p = 0.001), and LY9 (>8.22, p = 0.0003) had a shorter EFS than those with marker levels below the median. The effect of sCD23 on EFS differed between immunoglobulin heavy chain variable gene-mutated and unmutated patients, with the shortest EFS for unmutated CLL patients with sCD23 levels above the median. Taken together, our results validate the prognostic impact of sCD23 and highlight SPINT1 and LY9 as possible promising markers for treatment response in CLL patients
Relative survival reaches a plateau in hairy cell leukemia: A population-based analysis in The Netherlands
Diagnosis, treatment and supportive management of chronic lymphocytic leukemia:recommendations of the Dutch HOVON CLL working group
Management of patients with chronic lymphocytic leukemia (CLL) is changing due to considerable advances in the therapeutic armamentarium, and new therapies will possibly continue to emerge in the near future. Therefore, the CLL working group of the Dutch-Belgium Haemato-Oncology Cooperative Group for Adults in the Netherlands (HOVON) necessitated revising the Dutch CLL guidelines. The current guideline is based on the expert opinion of the HOVON CLL working group members and focusses on well-designed clinical trials taking into account efficacy with special emphasis on toxicity, treatment duration and treatment intensity. This article provides recommendations on diagnosis, treatment strategies in front-line and relapsed setting and provides supportive care measurements during novel-based therapies as well as for infectious CLL-related complications. The recommendations presented here are intended to provide guidance for the management of CLL patients in the Netherlands, and take into account the availability of treatment strategies at the time of this publication
