R-miniCHOP versus R-CHOP in elderly patients with diffuse large B-cell lymphoma: A propensity matched population-based study.

For elderly frail patients with diffuse large B-cell lymphoma (DLBCL), an attenuated chemo-immunotherapy strategy of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-miniCHOP) was introduced as a treatment option as from 2014 onward in the Netherlands. Although R-miniCHOP is more tolerable, reduction of chemotherapy could negatively affect survival compared to R-CHOP. The aim of this analysis was to assess survival of patients treated with R-miniCHOP compared to R-CHOP. DLBCL patients ≥65 years, newly diagnosed in 2014-2020, who received ≥1 cycle of R-miniCHOP or R-CHOP were identified in the Netherlands Cancer Registry, with survival follow-up through 2022. Patients were propensity-score-matched for baseline characteristics. Main endpoints were progression-free survival (PFS), overall survival (OS), and relative survival (RS). The use of R-miniCHOP in DLBCL increased from 2% in 2014 to 15% in 2020. In total, 384 patients treated with R-miniCHOP and 384 patients treated with R-CHOP were included for comparison (median age; 81 years, stage 3-4; 68%). The median number of R-(mini)CHOP cycles was 6 (range, 1-8). The 2-year PFS, OS and RS were inferior for patients treated with R-miniCHOP compared to R-CHOP (PFS 51% vs. 68%, p < .01; OS 60% vs. 75%, p < .01; RS 69% vs. 86%, p < .01). In multivariable analysis, patients treated with R-miniCHOP had higher risk of all-cause mortality compared to patients treated with R-CHOP (HR 1.73; 95%CI, 1.39-2.17). R-miniCHOP is effective for most elderly patients. Although survival is inferior compared to R-CHOP, the use of R-miniCHOP as initial treatment is increasing. Therefore, fitness needs to be carefully weighed in treatment selection.

Sofosbuvir and Simeprevir for the Treatment of Recurrent Hepatitis C with Fibrosing Cholestatic Hepatitis after Liver Transplantation.

Fibrosing cholestatic hepatitis (FCH) is an aggressive form of hepatitis C virus (HCV) recurrence after orthotopic liver transplantation (OLT), which frequently results in graft failure and death. Treatment of FCH remains challenging, and the optimal antiviral therapy is yet to be determined. Between November 2013 and early 2015, 62 patients with HCV cirrhosis underwent OLT at our transplant center, of whom, 5 patients developed recurrence HCV in the form of severe FCH and were treated with sofosbuvir and simeprevir (SOF-SMV) for 24 weeks. All patients achieved significant improvement of HCV viral load and had undetectable viral PCR at 6-8 week of treatment. The HCV RNA remained undetectable throughout treatment course. The first two patients achieved SVR at week 12 after completion of the treatment. There were significant histologic and biomarkers improvements after initiation of the treatment. One patient developed refractory pruritus and acute pancreatitis. The second, fourth and fifth patients had very benign treatment courses with no side effects recorded. The third patient was starting the treatment with multiple comorbid conditions. His course was complicated with hepatic artery thrombosis, and later developed sepsis and renal failure. Therefore, it seems that the combination of SOF-SMV is an efficacious oral regimen in OLT recipient with recurrent hepatitis C and FCH. However, safety profile needs to be carefully evaluated.

Healthcare utilisation in patients with breast cancer or non-Hodgkin lymphoma who experienced febrile neutropenia in the Netherlands: a retrospective matched control study using the PHARMO database.

Few data have been published on healthcare resource utilisation associated with chemotherapy-induced febrile neutropenia (FN) in Europe. Using the PHARMO record linkage system, we identified incident adult patients with a primary hospital discharge diagnosis of breast cancer (BC) or non-Hodgkin lymphoma (NHL) from 1998 to 2008. Patients who experienced FN were matched 1:2 non-FN reference patients. Of 1033 BC patients, 80 (8%) had FN and were matched with 160 reference patients; and of 486 NHL patients, 95 (20%) had FN and 89 were matched with 178 reference patients. Significantly more FN patients were hospitalised for any cause than reference patients: BC, 81% vs. 24% (OR 12.6; 95% CI 5.7-27.8); NHL, 82% vs. 44% (OR 6.7; 95% CI 3.3-13.9). Median length of all-cause hospitalisation stay was higher for FN patients: BC, 4.0 vs. 1.0 days; NHL, 8.5 vs. 1.8 days. The median (interquartile range) number of medication treatments was higher for FN patients: BC, 5.5 (4.0-7.5) vs. 2.0 (2.0-4.0); NHL, 8.0 (5.0-11.0) vs. 3.0 (2.0-4.0). In conclusion, FN in patients with BC or NHL had increased healthcare utilisation compared with non-FN patients; thus, efforts to reduce FN are warranted to reduce cost and improve outcomes.

Diverging trends in incidence and mortality, and improved survival of non-Hodgkin's lymphoma, in the Netherlands, 1989-2007.

BACKGROUND: We studied progress in the fight against non-Hodgkin's lymphoma (NHL) in the Netherlands by describing the changes in incidence, treatment, relative survival, and mortality during 1989-2007. PATIENTS AND METHODS: We included all adult patients with NHL [i.e. all mature B-, T-, and natural killer (NK) cell neoplasms, with the exception of plasma cell neoplasms], newly diagnosed in the period 1989-2007 and recorded in the Netherlands Cancer Registry (n=55 069). Regular mortality data were derived from Statistics Netherlands. Follow-up was completed up to 1 January 2009. Annual percentages of change in incidence, mortality, and relative survival were calculated. RESULTS: The incidence of indolent B-cell and T- and NK-cell neoplasms rose significantly (estimated annual percentage change=1.2% and 1.3%, respectively); incidence of aggressive B-cell neoplasms remained stable. Mortality due to NHL remained stable between 1989 and 2003, and has decreased since 2003. Five-year relative survival rates rose from 67% to 75%, and from 43% to 52%, respectively, for indolent and aggressive mature B-cell neoplasms, but 5-year survival remained stable at 48% for T- and NK-cell neoplasms. CONCLUSIONS: In the Netherlands, incidence of indolent mature B-cell and mature T- and NK-cell neoplasms has increased since 1989 but remained stable for aggressive neoplasms. Survival increased for all mature B-cell neoplasms, preceding a declining mortality and increased prevalence of NHL (17 597 on 1 January 2008).

Feasibility of concurrent cisplatin and extended field radiation therapy (EFRT) using intensity-modulated radiotherapy (IMRT) for carcinoma of the cervix.

OBJECTIVES: To assess the acute tolerance of delivering concurrent cisplatin and extended field radiotherapy (EFRT) using intensity-modulated radiotherapy technique (IMRT) for cancer of the cervix. METHODS: All patients receiving definitive treatment for cervical cancer were treated with EFRT using IMRT technique and concurrent cisplatin. The treatment volume included the cervix, uterus, parametria, presacral space, upper vagina, pelvic, common iliac, and paraaortic nodes to the top of L1. All regions received 45 Gy (25 fractions) with a simultaneous boost to involved nodes (55 Gy/25 fractions). Patients were assessed weekly for toxicity and response. RESULTS: Twenty-two consecutive patients underwent treatment. All patients completed the prescribed course of EFRT. Median treatment length was 39.5 days (range 36-53). Treatment breaks of 2 and 3 days were required for bone marrow toxicity in 2 patients. The final week of chemotherapy was held in 2 patients because of neutropenia. No patient suffered acute or subacute grade 3 or 4 GI or GU toxicity. CONCLUSION: In this clinical study, an IMRT technique was used to successfully deliver EFRT with concurrent chemosensitization for cervical cancer. The technique was associated with an acceptable acute toxicity without significant treatment protraction. This new role for IMRT merits further evaluation with larger patient numbers and longer follow-up.
