    Objective: Due to new treatment options, survival rates in multiple myeloma (MM) are improving. Consequently, maintaining work and income is becoming more important for patients and society. Therefore, we aimed to explore the change in income and employment in patients with MM. Methods: Data from the Netherlands Cancer Registry of MM patients diagnosed between 2012 and 2017 were merged with socioeconomic data from Statistics Netherlands. Descriptive statistics were used to analyse total income, income from employment, and accumulated income before and after diagnosis. Results: Income from employment decreased by 45% in MM patients, between 1 year before and 4 years after diagnosis Four years after diagnosis, 35% of the patients were still employed, with an accumulated 5-year productivity loss of €121 million. Higher income loss from employment and job loss was observed in female patients, patients with more extensive disease, or those not treated with autologous stem cell transplant.Conclusion: Loss of (income from) employment among patients with MM was high, causing financial burden on the patient and society. With improving survival in MM, more research and awareness are needed to better assess the importance of income and work for MM patients and society.</p

    A population-based study of transformed marginal zone lymphoma:identifying outcome-related characteristics

    Histological transformation of marginal zone lymphoma (tMZL) into diffuse large B-cell lymphoma is associated with poor outcomes. Clinical characteristics associated with transformation risk and outcome after transformation are largely unknown due to scarcity of data. In this population-based study, competing risk analyses were performed to elucidate clinical characteristics associated with developing transformation among 1793 MZL patients using the Netherlands Cancer Registry. Cox regression analyses were performed to elucidate clinical characteristics associated with risk of relapse and mortality after transformation. Transformation occurred in 75 (4%) out of 1793 MZL patients. Elevated LDH and nodal MZL subtype at MZL diagnosis were associated with an increased risk, and radiotherapy with a reduced risk of developing tMZL. Most tMZL patients received R-(mini)CHOP (n = 53, 71%). Age &gt;60 years and (immuno)chemotherapy before transformation were associated with an increased risk of relapse and mortality after transformation. Two-year progression-free survival (PFS) and overall survival (OS) were 66% (95% CI 52-77%) and 75% (95% CI 62-85%) for R-(mini)CHOP-treated tMZL patients, as compared to a PFS and OS both of 41% (95% CI 19-63%) for patients treated otherwise. Our study offers comprehensive insights into characteristics associated with transformation and survival after transformation, thereby optimizing guidelines and patient counseling.</p

    Impact of rituximab biosimilars on overall survival in diffuse large B-cell lymphoma:a Dutch population-based study

    In 2017, the European Medicines Agency approved rituximab biosimilars (R-biosimilars) for treatment of diffuse large B-cell lymphoma (DLBCL). Thereafter, the Netherlands was one of the first countries to implement R-biosimilars, given lower costs compared with rituximab originator (R-originator). This study's objective was to investigate whether overall survival (OS) of patients with DLBCL receiving R-biosimilars is similar to patients treated with R-originator. DLBCL patients ≥18 years, diagnosed between 2014 and 2018, who received at least 1 cycle of rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) were identified in the Netherlands Cancer Registry. Patients were categorized into R-originator or R-biosimilars groups based on data from a central repository of the Dutch medicinal drug market. The primary end point was 3-year OS, defined as the time between diagnosis and all-cause death. By the end of 2018, 91% of purchased rituximab were biosimilars. In total, 4429 patients were identified with 876 in the R-biosimilars group and 3553 in the R-originator group. Patients in the R-biosimilars group less frequently received .6 cycles of R-CHOP compared with patients treated with R-originator (24% vs 30%, P 5 .003). The 3-year OS did not differ between patients treated with R-originator or R-biosimilars (73% vs 73%, P = .855). This was confirmed with a multivariable Cox regression analysis accounting for sex, age, International Prognostic Index score, and number of R-CHOP cycles. In conclusion, the 3-year OS is similar for patients treated with CHOP in combination with R-originator or R-biosimilars and, therefore, favors the use of R-biosimilars in DLBCL treatment management
