Article Synopsis
  • Sentinel lymph node biopsy (SLNB) is crucial for staging in primary cutaneous melanoma, but its influence on outcomes in metastatic melanoma patients without adjuvant therapy was investigated.
  • The study analyzed data from 2,581 patients with advanced melanoma, comparing those who had SLNB before progression to those treated only with wide local excision (WLE).
  • Results showed longer melanoma-specific survival (MSS) in the SLNB group, but it was not an independent predictor of better outcomes in advanced melanoma cases.

Objective: To examine stage-specific trends in the incidence and survival of cutaneous melanoma in the Netherlands between 2003 and 2018, as well as the uptake of the sentinel lymph node biopsy (SLNB) and novel drugs during that period.

Methods: Data were obtained from the nationwide population-based Netherlands Cancer Registry for all patients diagnosed with invasive primary cutaneous melanoma (n = 60,267). We presented age-standardized incidence rates, the proportion of patients with an SLNB, the proportion of patients who received a novel drug (for their primary diagnosis) and one- and five-year relative survival rates.

The aim of this study was to provide insight into real-world healthcare costs of patients initially diagnosed with localized or regionally advanced melanoma in three Dutch hospitals between 2003 and 2011. Patients were stratified according to their stage at diagnosis and recurrence status. Costs were calculated by applying unit costs to individual patient resource use and reported for the full disease course, the initial treatment episode, and treatment episodes for disease recurrence (stratified by type of recurrence).

Importance: Although the number of treatments for elderly patients with non-transplant-eligible (NTE) multiple myeloma (MM) has increased substantially, evidence is lacking on the clinical effectiveness and cost-effectiveness of novel treatment sequences.

Objective: To determine the optimal sequence of treatment for patients with NTE MM from the perspective of the patient, physician, and society.

Design, Setting, And Participants: Using data from a Dutch observational registry, this economic evaluation combined evidence from network meta-analyses in a patient-level simulation model and modeled time-to-event and types of events from a hospital perspective with a lifetime horizon.

Opportunities for surgical treatment in metastatic melanoma patients have re-emerged due to the development of novel systemic therapeutics over the past decade. The aim of this study is to present data on outcomes of surgery in patients with unresectable stage IIIC and IV melanoma, who have previously been treated with immunotherapy or targeted therapy. Data was extracted from the Dutch Melanoma Treatment Registry (DMTR) on 154 patients obtaining disease control to systemic therapy and undergoing subsequent surgery.

Decision making for patients with multiple myeloma (MM) not transplant eligible (NTE) is complicated by a lack of head-to-head comparisons of standards of care, the increase in the choice of treatment modalities, and the promising results that are rapidly evolving from studies with novel regimens. To support evidence-based decision making, we performed a network meta-analysis for NTE MM patients that synthesizes direct and indirect evidence and enables a comparison of all treatments. Relevant randomized clinical trials were identified by a systematic literature review in EMBASE®, MEDLINE®, MEDLINE®-in-Process and the Cochrane Central Register of Controlled Trials for January 1999 to March 2016.

There is little evidence on the costs associated with the route of administration of oncology drugs. We investigated time and resource use for hospitals and patients and compared healthcare and societal costs for intravenous (IV) and subcutaneous (SC) administration of trastuzumab and rituximab. Data for the preparation and administration of both drugs were collected at the hospital pharmacy and at the oncology day care unit.

The aim of this population-based study was to identify the factors associated with clinical outcomes in vemurafenib-treated patients and to evaluate outcomes across subgroups of patients with different risk profiles. Data were retrieved from the Dutch Melanoma Treatment Registry. Time to next treatment (TTNT) and overall survival (OS) of all metastatic melanoma patients who received vemurafenib between 2012 and 2015 were assessed using Kaplan-Meier estimates.

Phase III trials with ipilimumab showed an improved survival in patients with metastatic melanoma. We evaluated the use and safety of ipilimumab, and the survival of all patients with metastatic cutaneous melanoma (N=807) receiving ipilimumab in real-world clinical practice in The Netherlands using data from the Dutch Melanoma Treatment Registry. Patients who were registered between July 2012 and July 2015 were included and analyzed according to their treatment status: treatment-naive (N=344) versus previously-treated (N=463).

Background: In an ageing population, it is inevitable to improve the management of care for community-dwelling elderly with incontinence. A previous study showed that implementation of the Optimum Continence Service Specification (OCSS) for urinary incontinence in community-dwelling elderly with four or more chronic diseases results in a reduction of urinary incontinence, an improved quality of life, and lower healthcare and lower societal costs. The aim of this study was to explore future consequences of the OCSS strategy of various healthcare policy scenarios in an ageing population.

Purpose Since 2000, many new treatment options have become available for relapsed and/or refractory multiple myeloma (R/R MM) after a long period in which dexamethasone and melphalan had been the standard treatment. Direct comparisons of these novel treatments, however, are lacking. This makes it extremely difficult to evaluate the relative added value of each new treatment.

Decision makers increasingly request evidence on the real-world cost effectiveness of a new treatment. There is, however, a lack of practical guidance on how to conduct an economic evaluation based on registry data and how this evidence can be used in actual decision making. This paper explains the required steps on how to perform a sound economic evaluation using examples from an economic evaluation conducted with real-world data from the Dutch Population based HAematological Registry for Observational Studies.

Policymakers more often request outcomes research for expensive therapies to help resolve uncertainty of their health benefits and budget impact at reimbursement. Given the limitations of observational data, we assessed its usefulness in evaluating clinical outcomes for bortezomib in advanced multiple myeloma patients. Data were retrospectively collected from patients included in the pivotal Assessment of Proteasome Inhibition for Extending Remissions trial (APEX; n=333) and two groups of daily practice patients treated with bortezomib following progression from upfront therapy (n=201): real-world patients treated as of May 2009 (RW-1; n=72) and June 2012 (RW-2; n=129).
